1. How do developmental scientists study people?
The scientific method is utilized by most researchers to arrive at sound conclusions in either quantitative or qualitative research. The experiment and the case study are two forms of research often used.

There are many forms of data collection, including:

Observation

Performance Measures

Self-Reports

Cross-Sectional and Longitudinal studies are also used:

Cross-Sectional: usually compare various age groups

Longitudinal: study changes or continuity of participants over a span of time.

2. What ethical problems may arise in research with humans?
There are a variety of ethical problems that can arise in research with humans and animals alike.  These issues are addressed in the APA code for Ethics. Some of the issues addressed are:

Guaranteed confidentiality and privacy rights

Protection from harm (including loss of dignity)

Rights to informed consent

Avoidance of deception

1. What purposes do theories serve?

A theory is the most important part of any scientific research, Social Sciences included. Theories are used as the basis for understanding certain behaviors and the human mind.

It is an original idea that is used as the framework to provide explanations for collected data or observations.

A theory is also used to generate hypothesis, which can be tested by research or an experiment.

Theories can evolve over time as things are forever changing, and inspire further or future research.

2. What are two (2) theoretical issues on which developmental scientists differ?
Developmental Theories differ based on a couple of different issues:

1. Existence of the stages of development

2. Importance of the environment and genetics/heredity

3. Active and Passive character of development

With that being said, there are two main theoretical models/issues that theorists subscribe to:

Mechanistic Model of Development: Can be compared to that of a machine—organism is primarily reactive to nature and doesn’t serve as the source for it’s own development and acts. Only reacts to factors of the outside and surrounding environment and influences. Organisms are reactive and passive and there is no direction towards and ultimate goal.

Organismic Model: The biological organism. An organism is composed of interconnected and interrelated parts that form an organized, but complex, system. The organism is viewed as active rather than passive. Accordingly, the biological organism view change and movement from within one’s self as opposed to a response from environmental or outside factors.
