One of my favorite labs we completed in Biology 151 was when we played different games to test our response time. When performing this tests, I often would click too early or too late. I never seemed to be able to click fast enough.

During this game, I didn't understand the thought process I used to complete this game, however, I now know that I used the information processing model. The model starts with a stimulus (input). In the game, the stimulus was the sheep beginning to move. The next step was stimulus identification, which occurred when I realized the sheep was moving. Next, is the response selection. Since the game only has one response (clicking once), this step was rather fast. Then there was response programming. I had to retrieve the motor program for finger movement in order to click. The last step was the movement (output). I finally clicked the screen in order to stop the sheep.

Each stage of the process was affected by the step before it. If I messed up the response program, then I would have a slower response time. This is most likely one of the reasons I failed to click fast enough in order to stop the sheep.

One of the best ways to learn how to play an instrument is by getting feedback after each set of notes. I went through this experience when learning how to play the cello and piano. The majority of the time those who are playing an instrument receive augmented feedback. As you see in the example video, a scene from Whiplash, the drummer thinks he is performing really well until the professor says the he needs to redo a section of the notes. After he restarts the section each time, the professor was giving the student augmented feedback. Augmented feedback can enhance skill acquisition by increasing the level of performance at a faster rate than if they person didn't receive augmented feedback.

Those who have been playing an instrument for multiple years, they use intrinsic feedback to improve their performance. For example, when they play a note or strand of notes off key, they are able to tell because they can hear the difference in the sound between the notes.

In the world of athletic training, being able to do a sideline concussion test is important. Included in the concussion evaluation is testing the athlete's memory. To be specific, the athletic trainer is testing the athlete's short term memory (looking for retrograde amnesia). One way to test this is by giving the athlete five words to remember in the beginning of the exam. You have them repeat them back to you immediately. Then every five to ten minutes, you ask them to repeat the words back to you. If they are unable to recall the words, it is one positive sign of a concussion. Since you are having the athlete memorize five words for a longer period of time, they get transferred from short-term to long-term memory.

There are two reasons as to why concussed athletes are unable to recall a certain memory. The first reason is trace decay, which means that as time continues on, the harder it is to recall information. Secondly, there is retroactive interference involved, which is interfering activity occurs during retention. For those are are concussed, they have intracranial swelling of the brain which can interfere with a person's memory.

I Spy was a common game played as a child. There were specific books for I Spy and you could also play it during long car rides. Little did we know as children, that when were were looking for the object in question, we were using visual search.

Visual search is the process of directing visual attention to locate relevant environmental cues. People use visual clues in order to help them with visual searching. Visual cues use feature integration theory and movement filtering. For example, when you are " I Spying" for something green, you automatically look outside to the trees because the color is a unique feature of the object. People also tend to bring their attention to objects that move. The trees are another example if you were in a car because they look like they are moving.

Experts in the task perform more efficient visual searches. Thus, if you did a lot of I Spy games as a child, you are probably better at spotting a certain object in a pile.

In the video, a little boy was creative with cooking dinner. Instead of running back and forth from the kitchen to the living room the boy decided to bring the kitchen to the living room. From personal experience, I know that when I am trying to cook while watching TV, I always end up burning the food.

When two tasks are performed there a four possible outcomes. The first would be that task A and task B can be performed equally well. One task could suffer in performance, while the other task remains unaffected or both tasks could suffer. Lastly, one task could be prevented while the other task continues on.

In the case of the video, both tasks seem to be performed equally well. This is able to occur because one task must be autonomic and doesn't require attention. The kid in the video is automatically watching TV, while cooking dinner for his family. Cooking is more detailed and has specific directions which is why his attention is focused on that.

The kids are cooking. Dinner while watching TV. Lol
