Extinction

If a stimulus is never reinforced, then the response will go away.

Generalization

A response can be generalized to other like stimuli. All spiders are scary.

Variations Within Classical Conditioning

After extinction, a response will suddenly reappear. Learn not to respond to CS.

Spontaneous Recovery

Page 22: Cat Video. Cat Roundup Learning  Learning  Lasting change in an organism’s behavior due to experience  Learning  Lasting change in an organism’s.

Generalization is a behavior that spreads from one situation to a similar one. (A baby will call Daddy “Dada.” When the baby sees any man, the baby calls out “Dada.”)

Discrimination is the reverse of generalization. Some stimuli have pleasant consequences and some do not. (A baby gradually learns that only one person responds with a smile when called “Dada.”)

Cognitive ProcessesCognitive Processes

Conditioning occurs best when the CS and UCS have just the sort of relationship that would lead a scientist to conclude that the CS causes the UCS. — even in classical conditioning, it is not only the simple stimulus-response association but also the thought that counts.

Mary Cover Jones used an early form of desensitization to prove that fears (phobias) could be unlearned.

Peter, a young boy, had an extreme fear of rabbits. Jones gave Peter his favorite food while slowly bringing the rabbit closer and closer. Eventually Peter no longer panicked around rabbits.

In shaping, successively closer versions of a desired response are reinforced (as in learning to play tennis).

In chaining, each part of a sequence is reinforced; the different parts are put together into a whole (as in learning the steps to a dance).

Operant Conditioning Processes

Primary Reinforcement is unlearned and usually necessary for survival. Food is the best example of a primary reinforcer.

Secondary Reinforcement is anything that comes to represent a primary reinforcer such as praise from a friend or a gold star on a homework assignment. Also called conditioned reinforcer.

Skinner’s emphasis on external control of behavior made him an influential, but controversial figure. Many psychologists criticized Skinner for underestimating the importance of cognitive and biological constraints.

Cognitive Approach

This approach emphasizes abstract and subtle learning that could not be achieved through conditioning or social learning alone.

Some learning is not intentional, but occurs almost accidentally—a situation called latent learning. Learning that occurs, but is not apparent until there is an incentive to demonstrate it

Expectancies are beliefs about our ability to perform an action and to get the desired reward. Expectancies affect learning.
