Behaviorism is a psychological perspective that explains the science of behavior by studying only observable behavior (eText).  It is a theory of psychology that claims all behaviors are learned through conditioning.

# data[].attributes.attachment_link.readable_text
Behaviorism is a theory of learning based on the idea that all behaviors are acquired through conditioning, and conditioning occurs through interaction with the environment. Behaviorists believe that our actions are shaped by environmental stimuli.

In simple terms, according to this school of thought, also known as behavioral psychology, behavior can be studied in a systematic and observable manner regardless of internal mental states. Behavioral theory also says that only observable behavior should be studied, as cognition, emotions, and mood are far too subjective.

Strict behaviorists believe that any person-regardless of genetic background, personality traits, and internal thoughts- can be trained to perform any task, within the limits of their physical capabilities. It only requires the right conditioning.

History of Behaviorism

Behaviorism was formally established with the 1913 publication of John B. Watson's classic paper, "Psychology as the Behaviorist Views It." It is best summed up by the following quote from Watson, who is often considered the father of behaviorism:

"Give me a dozen healthy infants, well-formed, and my own specified world to bring them up in and I'll guarantee to take any one at random and train him to become any type of specialist I might select-doctor, lawyer, artist, merchant-chief and, yes, even beggar-man and thief, regardless of his talents, penchants, tendencies, abilities, vocations, and race of his ancestors."

From about 1920 through the mid-1950s, behaviorism became the dominant school of thought in psychology. Some suggest that the popularity of behavioral psychology grew out of the desire to establish psychology as an objective and measurable science.

During that time, researchers were interested in creating theories that could be clearly described and empirically measured, but also used to make contributions that might have an influence on the fabric of everyday human lives.

Types of Behaviorism

There are two main types of behaviorism used to describe how behavior is formed.

Methodological Behaviorism

Methodological behaviorism states that observable behavior should be studied scientifically and that mental states and cognitive processes don't add to the understanding of behavior. Methodological behaviorism aligns with Watson's ideologies and approach.

Radical Behaviorism

Radical behaviorism is rooted in the theory that behavior can be understood by looking at one's past and present environment and the reinforcements within it, thereby influencing behavior either positively or negatively. This behavioral approach was created by the psychologist B.F. Skinner.

Classical Conditioning

Classical conditioning is a technique frequently used in behavioral training in which a neutral stimulus is paired with a naturally occurring stimulus. Eventually, the neutral stimulus comes to evoke the same response as the naturally occurring stimulus, even without the naturally occurring stimulus presenting itself.

Throughout the course of three distinct phases of classical conditioning, the associated stimulus becomes known as the conditioned stimulus and the learned behavior is known as the conditioned response.

Learning Through Association

The classical conditioning process works by developing an association between an environmental stimulus and a naturally occurring stimulus.

In physiologist Ivan Pavlov's classic experiments, dogs associated the presentation of food (something that naturally and automatically triggers a salivation response) at first with the sound of a bell, then with the sight of a lab assistant's white coat. Eventually, the lab coat alone elicited a salivation response from the dogs.

Factors That Impact Conditioning

During the first part of the classical conditioning process, known as acquisition, a response is established and strengthened. Factors such as the prominence of the stimuli and the timing of the presentation can play an important role in how quickly an association is formed.

When an association disappears, this is known as extinction. It causes the behavior to weaken gradually or vanish. Factors such as the strength of the original response can play a role in how quickly extinction occurs. The longer a response has been conditioned, for example, the longer it may take for it to become extinct.

Operant Conditioning

Operant conditioning, sometimes referred to as instrumental conditioning, is a method of learning that occurs through reinforcement and punishment. Through operant conditioning, an association is made between a behavior and a consequence for that behavior.

This behavioral approach says that when a desirable result follows an action, the behavior becomes more likely to happen again in the future. Conversely, responses followed by adverse outcomes become less likely to reoccur.

Consequences Affect Learning

Behaviorist B.F. Skinner described operant conditioning as the process in which learning can occur through reinforcement and punishment. More specifically: By forming an association between a certain behavior and the consequences of that behavior, you learn.

For example, if a parent rewards their child with praise every time they pick up their toys, the desired behavior is consistently reinforced and the child will become more likely to clean up messes.

Timing Plays a Role

The process of operant conditioning seems fairly straightforward-simply observe a behavior, then offer a reward or punishment. However, Skinner discovered that the timing of these rewards and punishments has an important influence on how quickly a new behavior is acquired and the strength of the corresponding response.

This makes reinforcement schedules important in operant conditioning. These can involve either continuous or partial reinforcement.

Continuous reinforcement involves rewarding every single instance of a behavior. It is often used at the beginning of the operant conditioning process. Then, as the behavior is learned, the schedule might switch to one of partial reinforcement.

Partial reinforcement involves offering a reward after a number of responses or after a period of time has elapsed. Sometimes, partial reinforcement occurs on a consistent or fixed schedule. In other instances, a variable and unpredictable number of responses or amount of time must occur before the reinforcement is delivered.

Uses for Behaviorism

The behaviorist perspective has a few different uses, including some related to education and mental health.

Behaviorism can be used to help students learn, such as by influencing lesson design. For instance, some teachers use consistent encouragement to help students learn (operant conditioning) while others focus more on creating a stimulating environment to increase engagement (classical conditioning).

One of the greatest strengths of behavioral psychology is the ability to clearly observe and measure behaviors. Because behaviorism is based on observable behaviors, it is often easier to quantify and collect data when conducting research.

Mental Health

Behavioral therapy was born from behaviorism and originally used in the treatment of autism and schizophrenia. This type of therapy involves helping people change problematic thoughts and behaviors, thereby improving mental health.

Effective therapeutic techniques such as intensive behavioral intervention, behavior analysis, token economies, and discrete trial training are all rooted in behaviorism. These approaches are often very useful in changing maladaptive or harmful behaviors in both children and adults.

Impact of Behaviorism

Several thinkers influenced behavioral psychology.Among these are Edward Thorndike, a pioneering psychologist who described the law of effect, and Clark Hull, who proposed the drive theory of learning.

There are a number of therapeutic techniques rooted in behavioral psychology. Though behavioral psychology assumed more of a background position after 1950, its principles still remain important.

Even today, behavior analysis is often used as a therapeutic technique to help children with autism and developmental delays acquire new skills. It frequently involves processes such as shaping (rewarding closer approximations to the desired behavior) and chaining (breaking a task down into smaller parts, then teaching and chaining the subsequent steps together).

Criticisms of Behaviorism

Many critics argue that behaviorism is a one-dimensional approach to understanding human behavior. They suggest that behavioral theories do not account for free will or internal influences such as moods, thoughts, and feelings.

Freud, for example, felt that behaviorism failed by not accounting for the unconscious mind's thoughts, feelings, and desires, which influence people's actions. Other thinkers, such as Carl Rogers and other humanistic psychologists, believed that behaviorism was too rigid and limited, failing to take into consideration personal agency.

More recently, biological psychology has emphasized the role the brain and genetics play in determining and influencing human actions. The cognitive approach to psychology focuses on mental processes such as thinking, decision-making, language, and problem-solving. In both cases, behaviorism neglects these processes and influences in favor of studying only observable behaviors.

Behavioral psychology also does not account for other types of learning that occur without the use of reinforcement and punishment. Moreover, people and animals can adapt their behavior when new information is introduced, even if that behavior was established through reinforcement.

A Word From Verywell

While the behavioral approach might not be the dominant force that it once was, it has still had a major impact on our understanding of human psychology. The conditioning process alone has been used to understand many different types of behaviors, ranging from how people learn to how language develops.

But perhaps the greatest contributions of behavioral psychology lie in its practical applications. Its techniques can play a powerful role in modifying problematic behavior and encouraging more positive, helpful responses. Outside of psychology, parents, teachers, animal trainers, and many others make use of basic behavioral principles to help teach new behaviors and discourage unwanted ones.

Frequently Asked Questions

John B. Watson is known as the founder of behaviorism. Though others had similar ideas in the early 1900s, when behavioral theory began, some suggest that Watson is credited as behavioral psychology's founder due to being "an attractive, strong, scientifically accomplished, and forceful speaker and an engaging writer" who was willing to share this behavioral approach when other psychologists were less likely to speak up.

How is behaviorism used in education?

Behaviorism can be used to help elicit positive behaviors or responses in students, such as by using reinforcement. Teachers with a behavioral approach often use "skill and drill" exercises to reinforce correct responses through consistent repetition, for instance.

Other ways reinforcement-based behaviorism can be used in education include praising students for getting the right answer and providing prizes for those who do well. Using tests to measure performance enables teachers to measure observable behaviors and is, therefore, another behavioral approach.

What makes behaviorism different from psychoanalysis?

Behaviorism says that behavior is a result of environment, the environment being an external stimulus. Psychoanalysis is the opposite of this, in that it is rooted in the belief that behavior is a result of an internal stimulus. Psychoanalytic theory is based on behaviors being motivated by one's unconscious mind, thus resulting in actions that are consistent with their unknown wishes and desires.

What is cognitive behaviorism?

Whereas strict behaviorism has no room for cognitive influences, cognitive behaviorism operates on the assumption that behavior is impacted by thoughts and emotions. Cognitive behavioral therapy (CBT), for instance, attempts to change negative behaviors by changing the destructive thought patterns behind them.

The first psychological work on behaviorism was carried out by Russian psychologist Ivan Pavlov.  Pavlov worked with dogs, attempting to study the possibility of learned behavior, or conditioned reflexes.  When he gave dogs food, they salivated.  He then started pairing their meals with the ringing of bells.  Eventually, the dogs simply salivated at the sound of the bells, even with no food present.  This was one of the classic conditioning experiments.  John B. Watson studied Pavlov’s work and created his own psychological perspective known as behaviorism.  Watson did not support the study of the consciousness because he believed it was impossible to statistically measure.  Accordingly, he shifted his focus to observable behavior only because data was quantifiable.  His work pondered on the question, “Is it possible to control behavior?”   B.F. Skinner was a later behaviorist in the early 20th century that carried on the work of Watson and her legacy was rooted in her experiments in the “Skinner box.”

# data[].attributes.attachment_link.readable_text
Behavioral Psychology

Early work in the field of behavior was conducted by the Russian physiologist Ivan Pavlov (1849-1936). Pavlov studied a form of learning behavior called a conditioned reflex, in which an animal or human produced a reflex (unconscious) response to a stimulus and, over time, was conditioned to produce the response to a different stimulus that the experimenter associated with the original stimulus. The reflex Pavlov worked with was salivation in response to the presence of food. The salivation reflex could be elicited using a second stimulus, such as a specific sound, that was presented in association with the initial food stimulus several times. Once the response to the second stimulus was "learned," the food stimulus could be omitted. Pavlov's "classical conditioning" is only one form of learning behavior studied by behaviorists.

John B. Watson (1878-1958) was an influential American psychologist whose most famous work occurred during the early 20th century at Johns Hopkins University. While Wundt and James were concerned with understanding conscious experience, Watson thought that the study of consciousness was flawed. Because he believed that objective analysis of the mind was impossible, Watson preferred to focus directly on observable behavior and try to bring that behavior under control. Watson was a major proponent of shifting the focus of psychology from the mind to behavior, and this approach of observing and controlling behavior came to be known as behaviorism. A major object of study by behaviorists was learned behavior and its interaction with inborn qualities of the organism. Behaviorism commonly used animals in experiments under the assumption that what was learned using animal models could, to some degree, be applied to human behavior. Indeed, Tolman (1938) stated, "I believe that everything important in psychology (except ... such matters as involve society and words) can be investigated in essence through the continued experimental and theoretical analysis of the determiners of rat behavior at a choice-point in a maze."

Behaviorism dominated experimental psychology for several decades, and its influence can still be felt today (Thorne & Henley, 2005). Behaviorism is largely responsible for establishing psychology as a scientific discipline through its objective methods and especially experimentation. In addition, it is used in behavioral and cognitive-behavioral therapy. Behavior modification is commonly used in classroom settings. Behaviorism has also led to research on environmental influences on human behavior.

B. F. Skinner (1904-1990) was an American psychologist. Like Watson, Skinner was a behaviorist, and he concentrated on how behavior was affected by its consequences. Therefore, Skinner spoke of reinforcement and punishment as major factors in driving behavior. As a part of his research, Skinner developed a chamber that allowed the careful study of the principles of modifying behavior through reinforcement and punishment. This device, known as an operant conditioning chamber (or more familiarly, a Skinner box), has remained a crucial resource for researchers studying behavior (Thorne & Henley, 2005).

The Skinner box is a chamber that isolates the subject from the external environment and has a behavior indicator such as a lever or a button. When the animal pushes the button or lever, the box is able to deliver a positive reinforcement of the behavior (such as food) or a punishment (such as a noise) or a token conditioner (such as a light) that is correlated with either the positive reinforcement or punishment.

Skinner's focus on positive and negative reinforcement of learned behaviors had a lasting influence in psychology that has waned somewhat since the growth of research in cognitive psychology. Despite this, conditioned learning is still used in human behavioral modification. Skinner's two widely read and controversial popular science books about the value of operant conditioning for creating happier lives remain as thought-provoking arguments for his approach (Greengrass, 2004).

During the early 20th century, American psychology was dominated by behaviorism and psychoanalysis. However, some psychologists were uncomfortable with what they viewed as limited perspectives being so influential to the field. They objected to the pessimism and determinism (all actions driven by the unconscious) of Freud. They also disliked the reductionism, or simplifying nature, of behaviorism. Behaviorism is also deterministic at its core, because it sees human behavior as entirely determined by a combination of genetics and environment. Some psychologists began to form their own ideas that emphasized personal control, intentionality, and a true predisposition for "good" as important for our self-concept and our behavior. Thus, humanism emerged.

Maslow, Rogers, and Humanism

Humanism is a perspective within psychology that emphasizes the potential for good that is innate to all humans. Two of the most well-known proponents of humanistic psychology are Abraham Maslow and Carl Rogers (O'Hara, n.d.). Abraham Maslow (1908-1970) was an American psychologist who is best known for proposing a hierarchy of human needs in motivating behavior. Although this concept will be discussed in more detail in a later section, a brief overview will be provided here.

Maslow asserted that so long as basic needs necessary for survival were met (e.g., food, water, shelter), higher-level needs (e.g., social needs) would begin to motivate behavior. According to Maslow, the highest-level needs relate to self-actualization, a process by which we achieve our full potential. Obviously, the focus on the positive aspects of human nature that are characteristic of the humanistic perspective is evident (Thorne & Henley, 2005).

Humanistic psychologists rejected, on principle, the research approach based on reductionist experimentation in the tradition of the physical and biological sciences, because it missed the "whole" human being. Beginning with Maslow and Rogers, there was an insistence on a humanistic research program. This program has been largely qualitative (not measurement-based), but there exist a number of quantitative research strains within humanistic psychology, including research on happiness, self-concept, meditation, and the outcomes of humanistic psychotherapy (Friedman, 2008).

Carl Rogers (1902-1987) was also an American psychologist who, like Maslow, emphasized the potential for good that exists within all people. Rogers used a therapeutic technique known as client-centered therapy in helping his clients deal with problematic issues that resulted in their seeking psychotherapy. Unlike a psychoanalytic approach in which the therapist plays an important role in interpreting what conscious behavior reveals about the unconscious mind, client-centered therapy involves the patient taking a lead role in the therapy session. Rogers believed that a therapist needed to display three features to maximize the effectiveness of this particular approach: unconditional positive regard, genuineness, and empathy. Unconditional positive regard refers to the fact that the therapist accepts their client for who they are, no matter what he or she might say. Provided these factors, Rogers believed that people were more than capable of dealing with and working through their own issues (Thorne & Henley, 2005).

Humanism has been influential to psychology as a whole. Both Maslow and Rogers are well-known names among students of psychology (you will read more about both men later in this text), and their ideas have influenced many scholars. Furthermore, Rogers' client-centered approach to therapy is still commonly used in psychotherapeutic settings today (O'hara, n.d.).

The general assumptions of a behaviorist perspective are as follows:
1. All behavior is learned from external sources
-Behaviorists assume that behavior is not inherited, it is learned.  People are conditioned to do certain actions in a scenario based on past experiences with that same scenario.  For this reason, behaviorists believe that they can study how we learn it and even control people’s behavior.
2. Psychology is a science.
-This assumption means that psychology needs data, just as all other sciences do.  This is why behaviorists regard some branches of psychology, which focus on unconsciousness, flawed.  There is no way to have consisten, quantifiable data that way.  External behavior, on the other hand, is quite quantifiable.
3. Humans and animals exhibit similar conditioning.
-Many of the experiments and data that behaviorists have amassed over the years has come from animals.  This basic assumption simply qualifies that data in regards to its agreement with the human subject.
4. All behavior can be described as a response to a stimulus.
-This simple assumption qualifies the attempt to control behavior using stimuli.

Strengths:
1. Behaviorism centers its work on observable, quantifiable data, in the form of behavior.
-This makes it impossible for others to question the legitimacy of the experiments, a feat which some other perspectives cannot claim for themselves.
2. Behavioral experiments are universal and repeatable.
-This form of experimentation does not differ person to person, or animal to animal.  All behavior of any organism is learned.  This means that any experiment can be repeated with any person and should yield the same result.  Other psychological perspectives may find difficulty in finding consistency between people.
3. Useful for conditioning behavior in the real world.
-Behaviorism has been proven to be useful in therapy, schooling, parenting, child care, animal control, and many other real-world situations.  Behavior is learning how to be controlled, when need be, thanks to the work of behavioral psychologists.

Weaknesses:
1.  Behaviorism dos not factor in biology.
-Behaviorism solely focuses on the observable, external realities.  However, biological factors can account for certain behavior.  This may vary person to person, which is yet another problem.
2. Behaviorism does not explore the hidden, unconscious mind.  Watson founded behaviorism because he scorned Freud and Wundt for focusing too much on the mind.  Despite coming up with a brilliant perspective, there will always be mysteries left to explore about our minds.  It is important to delve into this unknown. In this sense, behaviorism is a bit one-dimensional.
3. Learned behavior is not always conditioned, and it can reverse just as quickly as it was learned.
-Almost all of behavioral experiments have involved reinforcement, punishment, and observable conditioning.  Sometimes, behavior is instinct.  Additionally, learned behavior can become “un-learned” very quickly, showing that although behavioral conditioning can be fallible.

Behavioral theory also says that only observable behavior should be studied, as cognition, emotions, and mood are far too subjective.

Strict behaviorists believe that any person-regardless of genetic background, personality traits, and internal thoughts- can be trained to perform any task, within the limits of their physical capabilities. It only requires the right conditioning.

History of Behaviorism

Behaviorism was formally established with the 1913 publication of John B. Watson's classic paper, "Psychology as the Behaviorist Views It." It is best summed up by the following quote from Watson, who is often considered the father of behaviorism:

"Give me a dozen healthy infants, well-formed, and my own specified world to bring them up in and I'll guarantee to take any one at random and train him to become any type of specialist I might select-doctor, lawyer, artist, merchant-chief and, yes, even beggar-man and thief, regardless of his talents, penchants, tendencies, abilities, vocations, and race of his ancestors."

From about 1920 through the mid-1950s, behaviorism became the dominant school of thought in psychology. Some suggest that the popularity of behavioral psychology grew out of the desire to establish psychology as an objective and measurable science.

During that time, researchers were interested in creating theories that could be clearly described and empirically measured, but also used to make contributions that might have an influence on the fabric of everyday human lives.

Types of Behaviorism

There are two main types of behaviorism used to describe how behavior is formed.

Methodological Behaviorism

Methodological behaviorism states that observable behavior should be studied scientifically and that mental states and cognitive processes don't add to the understanding of behavior. Methodological behaviorism aligns with Watson's ideologies and approach.

Radical Behaviorism

Radical behaviorism is rooted in the theory that behavior can be understood by looking at one's past and present environment and the reinforcements within it, thereby influencing behavior either positively or negatively. This behavioral approach was created by the psychologist B.F. Skinner.

Classical Conditioning

Classical conditioning is a technique frequently used in behavioral training in which a neutral stimulus is paired with a naturally occurring stimulus. Eventually, the neutral stimulus comes to evoke the same response as the naturally occurring stimulus, even without the naturally occurring stimulus presenting itself.

Throughout the course of three distinct phases of classical conditioning, the associated stimulus becomes known as the conditioned stimulus and the learned behavior is known as the conditioned response.

Learning Through Association

The classical conditioning process works by developing an association between an environmental stimulus and a naturally occurring stimulus.

In physiologist Ivan Pavlov's classic experiments, dogs associated the presentation of food (something that naturally and automatically triggers a salivation response) at first with the sound of a bell, then with the sight of a lab assistant's white coat. Eventually, the lab coat alone elicited a salivation response from the dogs.

Factors That Impact Conditioning

During the first part of the classical conditioning process, known as acquisition, a response is established and strengthened. Factors such as the prominence of the stimuli and the timing of the presentation can play an important role in how quickly an association is formed.

When an association disappears, this is known as extinction. It causes the behavior to weaken gradually or vanish. Factors such as the strength of the original response can play a role in how quickly extinction occurs. The longer a response has been conditioned, for example, the longer it may take for it to become extinct.

Operant Conditioning

Operant conditioning, sometimes referred to as instrumental conditioning, is a method of learning that occurs through reinforcement and punishment. Through operant conditioning, an association is made between a behavior and a consequence for that behavior.

This behavioral approach says that when a desirable result follows an action, the behavior becomes more likely to happen again in the future. Conversely, responses followed by adverse outcomes become less likely to reoccur.

Consequences Affect Learning

Behaviorist B.F. Skinner described operant conditioning as the process in which learning can occur through reinforcement and punishment. More specifically: By forming an association between a certain behavior and the consequences of that behavior, you learn.

For example, if a parent rewards their child with praise every time they pick up their toys, the desired behavior is consistently reinforced and the child will become more likely to clean up messes.

Timing Plays a Role

The process of operant conditioning seems fairly straightforward-simply observe a behavior, then offer a reward or punishment. However, Skinner discovered that the timing of these rewards and punishments has an important influence on how quickly a new behavior is acquired and the strength of the corresponding response.

This makes reinforcement schedules important in operant conditioning. These can involve either continuous or partial reinforcement.

Continuous reinforcement involves rewarding every single instance of a behavior. It is often used at the beginning of the operant conditioning process. Then, as the behavior is learned, the schedule might switch to one of partial reinforcement.

Partial reinforcement involves offering a reward after a number of responses or after a period of time has elapsed. Sometimes, partial reinforcement occurs on a consistent or fixed schedule. In other instances, a variable and unpredictable number of responses or amount of time must occur before the reinforcement is delivered.

Uses for Behaviorism

The behaviorist perspective has a few different uses, including some related to education and mental health.

Behaviorism can be used to help students learn, such as by influencing lesson design. For instance, some teachers use consistent encouragement to help students learn (operant conditioning) while others focus more on creating a stimulating environment to increase engagement (classical conditioning).

One of the greatest strengths of behavioral psychology is the ability to clearly observe and measure behaviors. Because behaviorism is based on observable behaviors, it is often easier to quantify and collect data when conducting research.

Mental Health

Behavioral therapy was born from behaviorism and originally used in the treatment of autism and schizophrenia. This type of therapy involves helping people change problematic thoughts and behaviors, thereby improving mental health.

Effective therapeutic techniques such as intensive behavioral intervention, behavior analysis, token economies, and discrete trial training are all rooted in behaviorism. These approaches are often very useful in changing maladaptive or harmful behaviors in both children and adults.

Impact of Behaviorism

Several thinkers influenced behavioral psychology.Among these are Edward Thorndike, a pioneering psychologist who described the law of effect, and Clark Hull, who proposed the drive theory of learning.

There are a number of therapeutic techniques rooted in behavioral psychology. Though behavioral psychology assumed more of a background position after 1950, its principles still remain important.

Even today, behavior analysis is often used as a therapeutic technique to help children with autism and developmental delays acquire new skills. It frequently involves processes such as shaping (rewarding closer approximations to the desired behavior) and chaining (breaking a task down into smaller parts, then teaching and chaining the subsequent steps together).

Criticisms of Behaviorism

Many critics argue that behaviorism is a one-dimensional approach to understanding human behavior. They suggest that behavioral theories do not account for free will or internal influences such as moods, thoughts, and feelings.

Freud, for example, felt that behaviorism failed by not accounting for the unconscious mind's thoughts, feelings, and desires, which influence people's actions. Other thinkers, such as Carl Rogers and other humanistic psychologists, believed that behaviorism was too rigid and limited, failing to take into consideration personal agency.

More recently, biological psychology has emphasized the role the brain and genetics play in determining and influencing human actions. The cognitive approach to psychology focuses on mental processes such as thinking, decision-making, language, and problem-solving. In both cases, behaviorism neglects these processes and influences in favor of studying only observable behaviors.

Behavioral psychology also does not account for other types of learning that occur without the use of reinforcement and punishment. Moreover, people and animals can adapt their behavior when new information is introduced, even if that behavior was established through reinforcement.

A Word From Verywell

While the behavioral approach might not be the dominant force that it once was, it has still had a major impact on our understanding of human psychology. The conditioning process alone has been used to understand many different types of behaviors, ranging from how people learn to how language develops.

But perhaps the greatest contributions of behavioral psychology lie in its practical applications. Its techniques can play a powerful role in modifying problematic behavior and encouraging more positive, helpful responses. Outside of psychology, parents, teachers, animal trainers, and many others make use of basic behavioral principles to help teach new behaviors and discourage unwanted ones.

John B. Watson is known as the founder of behaviorism. Though others had similar ideas in the early 1900s, when behavioral theory began, some suggest that Watson is credited as behavioral psychology's founder due to being "an attractive, strong, scientifically accomplished, and forceful speaker and an engaging writer" who was willing to share this behavioral approach when other psychologists were less likely to speak up.

# data[].attributes.body
1. Learning strategies differ from person to person
-People learn in many different way.  People may be auditory, visual, or kinesthetic learners, to name a few.  Thus, when behavioral psychologists attempt to control behavior by making it “learned,” results may vary from person to person because everyone learns differently.
2. Does not account for cognitive activity
-Thoughts, motivation, and cognition are all factors that affect one’s behavior.  However, behaviorism ignores the influences of these phenomena and solely focus on the outcome that they all produce.
3. Does not account for the social dimensions of learned behavior
-Behavior in people is affected by social situations.  This is obvious, as we are social creatures.  However, behaviorism usually ignores this becase it is hard to quantify.  A subject’s personality and social persona are not focused on in behaviorism.

# data[].attributes.attachment_link.readable_text
Behavior theory or behaviorism generally refers to a line of educational and psychological theories tracing back to psychologist B.F. Skinner, who broke learning down to fixed processes that generate measurable results. Skinner's theories, and the scholarship which built on them, had natural applications in teaching, child development and many social sciences. However, many disciplines have moved way from behavioral theory as their go-to philosophy to describe learning and socialization in and outside of the classroom.

Learning Strategies

One limit to behavioral theories is that people learn in different ways. Recent scholarship suggests that human development is far more complex than once imagined. Albert Bandura, a psychologist at Stanford University, states that numerous factors, ranging from genetics to life experience, shape each individual's optimal learning methods. This means that although two or more people may end up making the same choice on a mathematics test, the factors involved in making that choice could be radically different from one person to the next. Thus, training methods based on behaviorism may work for some students, but fail for others.

Cognitive Abilities

In situations where there is a common challenge and observable result, such as mathematics or vocabulary memorization test, a behavioralist approach will certainly help students achieve a positive result. For example, memorizing multiplication tables will lead to positive results on math tests and quizzes. However, students will encounter many other challenges where success is more difficult to measure. Today, scholars largely agree that learning is both behavioral and cognitive, meaning that it is not only important for students to complete tasks, but also to understand and interpret those tasks.

Open-Ended Challenges

For some challenges, learning methods can benefit from behavioral theories. Skills such as typing and elementary reading and writing will almost certainly improve with repeated training to eliminate errors and develop consistent competence. However, ask students to write a journal about their thoughts on "Charlotte's Web" or "The Adventures of Huckleberry Finn," and behavioral approaches begin to break down. Each student will have a slightly different feeling about the book, and none are necessarily wrong. The challenge is cognitive rather than behavioral. The student must not only be able to read and write properly, but also understand the text and develop a unique idea about it.

Continuing Education

When it comes to more nuanced challenges such as writing and analysis, recent scholarship embraces cognitive approaches rather than behavioral theories. According to Linda Flower, who works to develop new theories about learning and writing at Carnegie Mellon University, task-based approaches fail to consider how students overcome challenges. For example, behavioral theories do not account for how a student's individual memories and experience relate to how they interpret a book or approach a challenge they've never been trained to deal with.

What Are Main Limitations of Behavioral Theories?

# data[].attributes.attachment_link.description
Behavior theory or behaviorism generally refers to a line of educational and psychological theories tracing back to psychologist B.F. Skinner, who broke learning down to fixed processes that generate measurable results. Skinner's theories, and the scholarship which built on them, had natural applications in teaching, child development and many social sciences.

How Does Behaviorism Compare to Other Perspectives?

# data[].attributes.body
Behaviorism’s relations to the other perspectives of psychology:

Behaviorism was an approach to psychology that was founded in response to Sigmund Freud’s psychodynamic approach, which solely focused on the internal, covert actions of the mind and which stressed the importance of the unconscious.  Behaviorists thought that this idea was flawed, as it could not be tested reliably, since data was not necessarily empirical.  Behaviorism seems to pretty much be the opposite of psychoanalysis, as it focuses on observable, overt behaviors that behaviorists claimed are learned from the environment around us.  The cognitive perspective, while not dealing with the unconscious or the covert actions of the mind, focuses on the internal mental processes of people that can be “viewed” and recorded with brain scans and tests.  Again, behaviorism differs from this because behaviorism does not go inside the body.  For the same reason, behaviorism does not relate to the biological perspective, which deals with the biology of the body and mind.  In relation to the humanistic approach, which emphasizes the free will and drive to self-actualization of oneself, behaviorism contains some loose ties to it.  While humanism seems pretty subjective and without evidence, one can argue that the basic principles of it, such as free will, tie into decision making and how we determine our behavior.  The sociocultural psychological perspective can be tied into behaviorism, as part of it deals with the differences in behavior between cultures and the reasons for the discrepancies.  The evolutionary psychological perspective usually deals with the mental processes that are passed on universally, but evolution at its core can deal with the behaviors that allow organisms to survive and reproduce.

Looking at the comparisons between behaviorism and the other perspectives, I would say it is most similar to humanism and socioculturalism, and most different from the biological, cognitive, and psychodynamic approaches.  Behaviorism is very unique, especially in its solely external approach, as well as its perception about learned behavior.

Psychologists today do not believe there is one "right" way to study the way people think or behave. There are, however, various schools of thought that evolved throughout the development of psychology that continue to shape the way psychologists investigate human behavior. For example, some psychologists might attribute a certain behavior to biological factors such as genetics while another psychologist might consider early childhood experiences to be a more likely explanation for the behavior. Because psychologists might emphasize various points within psychology in their research and analysis of behavior, there are different viewpoints in psychology. These schools of thought are known as approaches, or perspectives.

Link to Learning: Review the five main psychological perspectives found HERE.

The Psychodynamic Perspective

Psychodynamic theory is an approach to psychology that studies the psychological forces underlying human behavior, feelings, and emotions, and how they may relate to early childhood experience. This theory is especially interested in the dynamic relations between conscious and unconscious motivation, and asserts that behavior is the product of underlying conflicts over which people often have little awareness.

Psychodynamic theory was born in 1874 with the works of German scientist Ernst von Brucke, who supposed that all living organisms are energy systems governed by the principle of the conservation of energy. During the same year, medical student Sigmund Freud adopted this new "dynamic" physiology and expanded it to create the original concept of "psychodynamics," in which he suggested that psychological processes are flows of psychosexual energy (libido) in a complex brain. Freud also coined the term "psychoanalysis." Later, these theories were developed further by Carl Jung, Alfred Adler, Melanie Klein, and others. By the mid-1940s and into the 1950s, the general application of the "psychodynamic theory" had been well established.

The Role of the Unconscious

Freud's theory of psychoanalysis holds two major assumptions: (1) that much of mental life is unconscious (i.e., outside of awareness), and (2) that past experiences, especially in early childhood, shape how a person feels and behaves throughout life. The concept of the unconscious was central: Freud postulated a cycle in which ideas are repressed but continue to operate unconsciously in the mind, and then reappear in consciousness under certain circumstances. Much of Freud's theory was based on his investigations of patients suffering from "hysteria" and neurosis. Hysteria was an ancient diagnosis that was primarily used for women with a wide variety of symptoms, including physical symptoms and emotional disturbances with no apparent physical cause. The history of the term can be traced to ancient Greece, where the idea emerged that a woman's uterus could float around her body and cause a variety of disturbances. Freud theorized instead that many of his patients' problems arose from the unconscious mind. In Freud's view, the unconscious mind was a repository of feelings and urges of which we have no awareness.

The treatment of a patient referred to as Anna O. is regarded as marking the beginning of psychoanalysis. Freud worked together with Austrian physician Josef Breuer to treat Anna O.'s "hysteria," which Freud implied was a result of the resentment she felt over her father's real and physical illness that later led to his death. Today many researchers believe that her illness was not psychological, as Freud suggested, but either neurological or organic.

The Id, Ego, and Superego

Freud's structural model of personality divides the personality into three parts-the id, the ego, and the superego. The id is the unconscious part that is the cauldron of raw drives, such as for sex or aggression. The ego, which has conscious and unconscious elements, is the rational and reasonable part of personality. Its role is to maintain contact with the outside world to keep the individual in touch with society, and to do this it mediates between the conflicting tendencies of the id and the superego. The superego is a person's conscience, which develops early in life and is learned from parents, teachers, and others. Like the ego, the superego has conscious and unconscious elements. When all three parts of the personality are in dynamic equilibrium, the individual is thought to be mentally healthy. However, if the ego is unable to mediate between the id and the superego, an imbalance is believed to occur in the form of psychological distress.

Psychosexual Theory of Development

Freud's theories also placed a great deal of emphasis on sexual development. Freud believed that each of us must pass through a series of stages during childhood, and that if we lack proper nurturing during a particular stage, we may become stuck or fixated in that stage. Freud's psychosexual model of development includes five stages: oral, anal, phallic, latency, and genital. According to Freud, children's pleasure-seeking urges are focused on a different area of the body, called an erogenous zone, at each of these five stages. Psychologists today dispute that Freud's psychosexual stages provide a legitimate explanation for how personality develops, but what we can take away from Freud's theory is that personality is shaped, in some part, by experiences we have in childhood.

Jungian Psychodynamics

Carl Jung was a Swiss psychotherapist who expanded upon Freud's theories at the turn of the 20th century. A central concept of Jung's analytical psychology is individuation: the psychological process of integrating opposites, including the conscious with the unconscious, while still maintaining their relative autonomy. Jung focused less on infantile development and conflict between the id and superego and instead focused more on integration between different parts of the person. Jung created some of the best-known psychological concepts, including the archetype, the collective unconscious, the complex, and synchronicity.

Psychodynamics Today

At present, psychodynamics is an evolving multidisciplinary field that analyzes and studies human thought processes, response patterns, and influences. Research in this field focuses on areas such as:

understanding and anticipating the range of conscious and unconscious responses to specific sensory inputs, such as images, colors, textures, sounds, etc.;

utilizing the communicative nature of movement and primal physiological gestures to affect and study specific mind-body states; and

examining the capacity of the mind and senses to directly affect physiological response and biological change.

Psychodynamic therapy, in which patients become increasingly aware of dynamic conflicts and tensions that are manifesting as a symptom or challenge in their lives, is an approach to therapy that is still commonly used today.

The Behavioral Perspective

Behaviorism is an approach to psychology that emerged in the early 20th century as a reaction to the psychoanalytic theory of the time. Psychoanalytic theory often had difficulty making predictions that could be tested using rigorous experimental methods. The behaviorist school of thought maintains that behaviors can be described scientifically without recourse either to internal physiological events or to hypothetical constructs such as thoughts and beliefs. Rather than focusing on underlying conflicts, behaviorism focuses on observable, overt behaviors that are learned from the environment.

Its application to the treatment of mental problems is known as behavior modification. Learning is seen as behavior change molded by experience; it is accomplished largely through either classical or operant conditioning (described below).

The primary developments in behaviorism came from the work of Ivan Pavlov, John B. Watson, Edward Lee Thorndike, and B. F. Skinner.

Ivan Pavlov and Classical Conditioning

The Russian physiologist Ivan Pavlov was widely known for describing the phenomenon now known as classical conditioning. In his famous 1890s experiment, he trained his dogs to salivate on command by associating the ringing of a bell with the delivery of food. As Pavlov's work became known in the West, particularly through the writings of John B. Watson, the idea of conditioning as an automatic form of learning became a key concept in the development of behaviorism.

Watson's "Little Albert" Experiment

John B. Watson was an American psychologist who is best known for his controversial "Little Albert" experiment. In this experiment, he used classical conditioning to teach a nine-month-old boy to be afraid of a white toy rat by associating the rat with a sudden loud noise. This study demonstrated how emotions could become conditioned responses.

Thorndike's Law of Effect

Edward Lee Thorndike was an American psychologist whose work on animal behavior and the learning process led to the "law of effect." The law of effect states that responses that create a satisfying effect are more likely to occur again, while responses that produce a discomforting effect become less likely to occur.

Skinner's Operant Conditioning

"Operant conditioning," a term coined by psychologist B. F. Skinner, describes a form of learning in which a voluntary response is strengthened or weakened depending on its association with either positive or negative consequences. The strengthening of a response occurs through reinforcement. Skinner described two types of reinforcement: positive reinforcement, which is the introduction of a positive consequence such as food, pleasurable activities, or attention from others, and negative reinforcement, which is the removal of a negative consequence such as pain or a loud noise. Skinner saw human behavior as shaped by trial and error through reinforcement and punishment, without any reference to inner conflicts or perceptions. In his theory, mental disorders represented maladaptive behaviors that were learned and could be unlearned through behavior modification.

Behaviorism Today

In the second half of the 20th century, behaviorism was expanded through advances in cognitive theories. While behaviorism and cognitive schools of psychological thought may not agree theoretically, they have complemented each other in practical therapeutic applications like cognitive-behavioral therapy (CBT), which has been used widely in the treatment of many different mental disorders, such as phobias, PTSD, and addiction.

Some behavior therapies employ Skinner's theories of operant conditioning: by not reinforcing certain behaviors, these behaviors can be extinguished. Skinner's radical behaviorism advanced a "triple contingency" model, which explored the links between the environment, behavior, and the mind. This later gave rise to applied behavior analysis (ABA), in which operant conditioning techniques are used to reinforce positive behaviors and punish unwanted behaviors. This approach to treatment has been an effective tool to help children on the autism spectrum; however, it is considered controversial by many who see it as attempting to change or "normalize" autistic behaviors (Lovaas, 1987, 2003; Sallows & Graupner, 2005; Wolf & Risley, 1967).

The Cognitive Perspective

Cognitive psychology is the school of psychology that examines internal mental processes such as problem solving, memory, and language. "Cognition" refers to thinking and memory processes, and "cognitive development" refers to long-term changes in these processes. Much of the work derived from cognitive psychology has been integrated into various other modern disciplines of psychological study, including social psychology, personality psychology, abnormal psychology, developmental psychology, educational psychology, and behavioral economics.

Cognitive psychology is radically different from previous psychological approaches in that it is characterized by both of the following:

1. It accepts the use of the scientific method and generally rejects introspection as a valid method of investigation, unlike phenomenological methods such as Freudian psychoanalysis.

2. It explicitly acknowledges the existence of internal mental states (such as belief, desire, and motivation), unlike behaviorist psychology.

Cognitive theory contends that solutions to problems take the form of algorithms, heuristics, or insights. Major areas of research in cognitive psychology include perception, memory, categorization, knowledge representation, numerical cognition, language, and thinking.

History of Cognitive Psychology

Cognitive psychology is one of the more recent additions to psychological research. Though there are examples of cognitive approaches from earlier researchers, cognitive psychology really developed as a subfield within psychology in the late 1950s and early 1960s. The development of the field was heavily influenced by contemporary advancements in technology and computer science.

Early Roots

In 1958, Donald Broadbent integrated concepts from human-performance research and the recently developed information theory in his book Perception and Communication, which paved the way for the information-processing model of cognition. Ulric Neisser is credited with formally having coined the term "cognitive psychology" in his book of the same name, published in 1967. The perspective had its foundations in the Gestalt psychology of Max Wertheimer, Wolfgang Köhler, and Kurt Koffka, and in the work of Jean Piaget, who studied intellectual development in children.

Although no one person is entirely responsible for starting the cognitive revolution, Noam Chomsky was very influential in the early days of this movement. Chomsky (1928-), an American linguist, was dissatisfied with the influence that behaviorism had had on psychology. He believed that psychology's focus on behavior was short-sighted and that the field had to reincorporate mental functioning into its purview if it were to offer any meaningful contributions to understanding behavior (Miller, 2003).

Jean Piaget's Theory of Cognitive Development

Instead of approaching development from a psychoanalytic or psychosocial perspective, Piaget focused on children's cognitive growth. He is most widely known for his stage theory of cognitive development, which outlines how children become able to think logically and scientifically over time. As they progress to a new stage, there is a distinct shift in how they think and reason.

The Humanistic Perspective

Humanistic psychology is a psychological perspective that rose to prominence in the mid-20th century, drawing on the philosophies of existentialism and phenomenology, as well as Eastern philosophy. It adopts a holistic approach to human existence through investigations of concepts such as meaning, values, freedom, tragedy, personal responsibility, human potential, spirituality, and self-actualization.

Basic Principles of the Humanistic Perspective

The humanistic perspective is a holistic psychological perspective that attributes human characteristics and actions to free will and an innate drive for self-actualization. This approach focuses on maximum human potential and achievement rather than psychoses and symptoms of disorder. It emphasizes that people are inherently good and pays special attention to personal experiences and creativity. This perspective has led to advances in positive, educational, and industrial psychology, and has been applauded for its successful application to psychotherapy and social issues. Despite its great influence, humanistic psychology has also been criticized for its subjectivity and lack of evidence.

Developments in Humanistic Psychology

In the late 1950s, a group of psychologists convened in Detroit, Michigan, to discuss their interest in a psychology that focused on uniquely human issues, such as the self, self-actualization, health, hope, love, creativity, nature, being, becoming, individuality, and meaning. These preliminary meetings eventually culminated in the description of humanistic psychology as a recognizable "third force" in psychology, along with behaviorism and psychoanalysis. Humanism's major theorists were Abraham Maslow, Carl Rogers, Rollo May, and Clark Moustakas; it was also influenced by psychoanalytic theorists, including Wilhelm Reich, who discussed an essentially good, healthy core self, and Carl Gustav Jung, who emphasized the concept of archetypes.

Maslow's Hierarchy of Needs

Abraham Maslow (1908-1970) is considered the founder of humanistic psychology, and is noted for his conceptualization of a hierarchy of human needs. He believed that every person has a strong desire to realize his or her full potential-or to reach what he called "self-actualization." Unlike many of his predecessors, Maslow studied mentally healthy individuals instead of people with serious psychological issues. Through his research he coined the term "peak experiences," which he defined as "high points" in which people feel at harmony with themselves and their surroundings. Self-actualized people, he believed, have more of these peak experiences throughout a given day than others.

To explain his theories, Maslow created a visual, which he termed the "hierarchy of needs." This pyramid depicts various levels of physical and psychological needs that a person progresses through during their lifetime. At the bottom of the pyramid are the basic physiological needs of a human being, such as food and water. The next level is safety, which includes shelter and needs paramount to physical survival. The third level, love and belonging, is the psychological need to share oneself with others. The fourth level, esteem, focuses on success, status, and accomplishments. The top of the pyramid is self-actualization, in which a person is believed to have reached a state of harmony and understanding. Individuals progress from lower to higher stages throughout their lives, and cannot reach higher stages without first meeting the lower needs that come before them.

Rogers' Person-Centered Therapy

Carl Rogers (1902-1987) is best known for his person-centered approach, in which the relationship between therapist and client is used to help the patient reach a state of realization, so that they can then help themselves. His non-directive approach focuses more on the present than the past and centers on clients' capacity for self-direction and understanding of their own development. The therapist encourages the patient to express their feelings and does not suggest how the person might wish to change. Instead, the therapist uses the skills of active listening and mirroring to help patients explore and understand their feelings for themselves.

Rogers is also known for practicing "unconditional positive regard," which is defined as accepting a person in their entirety with no negative judgment of their essential worth. He believed that those raised in an environment of unconditional positive regard have the opportunity to fully actualize themselves, while those raised in an environment of conditional positive regard only feel worthy if they match conditions that have been laid down by others.

May's Existentialism

Rollo May (1909-1994) was the best known American existential psychologist, and differed from other humanistic psychologists by showing a sharper awareness of the tragic dimensions of human existence. May was influenced by American humanism, and emphasized the importance of human choice.

Advantages and Disadvantages

Humanistic psychology is holistic in nature: it takes whole persons into account rather than their separate traits or processes. In this way, people are not reduced to one particular attribute or set of characteristics, but instead are appreciated for the complex beings that they are. Humanistic psychology allows for a personality concept that is dynamic and fluid and accounts for much of the change a person experiences over a lifetime. It stresses the importance of free will and personal responsibility for decision-making; this view gives the conscious human being some necessary autonomy and frees them from deterministic principles. Perhaps most importantly, the humanistic perspective emphasizes the need to strive for positive goals and explains human potential in a way that other theories cannot.

However, critics have taken issue with many of the early tenets of humanism, such as its lack of empirical evidence (as was the case with most early psychological approaches). Because of the inherent subjective nature of the humanistic approach, psychologists worry that this perspective does not identify enough constant variables in order to be researched with consistency and accuracy. Psychologists also worry that such an extreme focus on the subjective experience of the individual does little to explain or appreciate the impact of external societal factors on personality development. In addition, The major tenet of humanistic personality psychology-namely, that people are innately good and intuitively seek positive goals-does not account for the presence of deviance in the world within normal, functioning personalities.

The Socio-Cultural Perspective

Sociocultural factors are the larger-scale forces within cultures and societies that affect the thoughts, feelings, and behaviors of individuals. These include forces such as attitudes, child-rearing practices, discrimination and prejudice, ethnic and racial identity, gender roles and norms, family and kinship structures, power dynamics, regional differences, religious beliefs and practices, rituals, and taboos. Several subfields within psychology seek to examine these sociocultural factors that influence human mental states and behavior; among these are social psychology, cultural psychology, and cultural-historical psychology.

Cultural Psychology

Cultural psychology is the study of how psychological and behavioral tendencies are rooted and embedded within culture. The main tenet of cultural psychology is that mind and culture are inseparable and mutually constitutive, meaning that people are shaped by their culture and their culture is also shaped by them.

A major goal of cultural psychology is to expand the number and variation of cultures that contribute to basic psychological theories, so that these theories become more relevant to the predictions, descriptions, and explanations of all human behaviors-not just Western ones. Populations that are Western, educated, and industrialized tend to be overrepresented in psychological research, yet findings from this research tend to be labeled "universal" and inaccurately applied to other cultures. The evidence that social values, logical reasoning, and basic cognitive and motivational processes vary across populations has become increasingly difficult to ignore. By studying only a narrow range of culture within human populations, psychologists fail to account for a substantial amount of diversity.

Cultural psychology is often confused with cross-cultural psychology; however, it is distinct in that cross-cultural psychologists generally use culture as a means of testing the universality of psychological processes, rather than determining how local cultural practices shape psychological processes. So while a cross-cultural psychologist might ask whether Jean Piaget's stages of development are universal across a variety of cultures, a cultural psychologist would be interested in how the social practices of a particular set of cultures shape the development of cognitive processes in different ways.

Vygotsky and Cultural-Historical Psychology

Cultural-historical psychology is a psychological theory formed by Lev Vygotsky in the late 1920s and further developed by his students and followers in Eastern Europe and worldwide. This theory focuses on how aspects of culture, such as values, beliefs, customs, and skills, are transmitted from one generation to the next. According to Vygotsky, social interaction-especially involvement with knowledgeable community or family members-helps children to acquire the thought processes and behaviors specific to their culture and/or society. The growth that children experience as a result of these interactions differs greatly between cultures; this variance allows children to become competent in tasks that are considered important or necessary in their particular society.

Social Psychology

Social psychology is the scientific study of how people's thoughts, feelings, and behaviors are influenced by the actual, imagined, or implied presence of others. This subfield of psychology is concerned with the way such feelings, thoughts, beliefs, intentions, and goals are constructed, and how these psychological factors, in turn, influence our interactions with others.

Focus of Social Psychology

Social psychology typically explains human behavior as a result of the interaction of mental states and immediate social situations. Social psychologists, therefore, examine the factors that lead us to behave in a given way in the presence of others, as well as the conditions under which certain behaviors, actions, and feelings occur. They focus on how people construe or interpret situations and how these interpretations influence their thoughts, feelings, and behaviors (Ross & Nisbett, 1991). Thus, social psychology studies individuals in a social context and how situational variables interact to influence behavior.

Social psychologists assert that an individual's thoughts, feelings, and behaviors are very much influenced by social situations. Essentially, people will change their behavior to align with the social situation at hand. If we are in a new situation or are unsure how to behave, we will take our cues from other individuals.

The field of social psychology studies topics at both the intrapersonal level (pertaining to the individual), such as emotions and attitudes, and the interpersonal level (pertaining to groups), such as aggression and attraction. The field is also concerned with common cognitive biases-such as the fundamental attribution error, the actor-observer bias, the self-serving bias, and the just-world hypothesis-that influence our behavior and our perceptions of events.

History of Social Psychology

The discipline of social psychology began in the United States in the early 20th century. The first published study in this area was an experiment in 1898 by Norman Triplett on the phenomenon of social facilitation. During the 1930s, Gestalt psychologists such as Kurt Lewin were instrumental in developing the field as something separate from the behavioral and psychoanalytic schools that were dominant during that time.

During World War II, social psychologists studied the concepts of persuasion and propaganda for the U.S. military. After the war, researchers became interested in a variety of social problems including gender issues, racial prejudice, cognitive dissonance, bystander intervention, aggression, and obedience to authority. During the years immediately following World War II there was frequent collaboration between psychologists and sociologists; however, the two disciplines have become increasingly specialized and isolated from each other in recent years, with sociologists focusing more on macro-level variables (such as social structure).

The Biological Perspective

Biopsychology-also known as biological psychology or psychobiology-is the application of the principles of biology to the study of mental processes and behavior. The fields of behavioral neuroscience, cognitive neuroscience, and neuropsychology are all subfields of biological psychology.

Overview of Biopsychology

Biopsychologists are interested in measuring biological, physiological, and/or genetic variables and attempting to relate them to psychological or behavioral variables. Because all behavior is controlled by the central nervous system, biopsychologists seek to understand how the brain functions in order to understand behavior. Key areas of focus include sensation and perception, motivated behavior (such as hunger, thirst, and sex), control of movement, learning and memory, sleep and biological rhythms, and emotion. As technical sophistication leads to advancements in research methods, more advanced topics, such as language, reasoning, decision-making, and consciousness, are now being studied.

Behavioral neuroscience has a strong history of contributing to the understanding of medical disorders, including those that fall into the realm of clinical psychology. Neuropsychologists are often employed as scientists to advance scientific or medical knowledge, and neuropsychology is particularly concerned with understanding brain injuries in an attempt to learn about normal psychological functioning. Neuroimaging tools, such as functional magnetic resonance imaging (fMRI) scans, are often used to observe which areas of the brain are active during particular tasks in order to help psychologists understand the link between brain and behavior.

History

Biopsychology as a scientific discipline emerged from a variety of scientific and philosophical traditions in the 18th and 19th centuries. Philosophers like Rene Descartes proposed physical models to explain animal and human behavior. Descartes suggested, for example, that the pineal gland, a midline unpaired structure in the brain of many organisms, was the point of contact between mind and body. In The Principles of Psychology (1890), William James argued that the scientific study of psychology should be grounded in an understanding of biology. The emergence of both psychology and behavioral neuroscience as legitimate sciences can be traced to the emergence of physiology during the 18th and 19th centuries; however, it was not until 1914 that the term "psychobiology" was first used in its modern sense by Knight Dunlap in An Outline of Psychobiology.
