Are there practical applications of cognitive psychology? How is it possible to study the inner workings of the mind when we can’t really see the mind directly? What was the cognitive revolution?

All Rights Reserved.

Skinner interested in determining the relationship between stimuli and response Operant conditioning – Shape behavior by rewards or punishments – Rewarded behavior more likely to be repeated – Punished behavior that less likely to be repeated Behaviorism approach was dominant from the 1940s through the 1960s Goldstein, Cognitive Psychology: Connecting Mind, Research, and Everyday Experience, 5 th Edition. © 2023 Cengage.

Writing out the answers before checking your work will help you determine whether you know the material (and can reproduce it for an exam) or just recognize the material! 1. Describe Tolman’s experiment. 2. What would behaviorists predict would happen? 3. What did happen?

Tolman put rats in a four-armed maze, where they learned to turn right for food. He then placed them in the opposite arm to see where they went to get food. 2. What would behaviorists predict would happen? Behaviorists would predict that the rat would turn right because they learned that right turns = food. 3. What did happen? The rats went left to the arm that had food, indicating they had formed a cognitive map of the maze.
