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
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.

Watson & Raynor with Little Albert
Watson took a a baby named Albert and conditioned him to be afraid of white furry objects using Pavlov’s techniques.
Conditioned fear experiments such as Albert’s experience would never occur
today because of the existing ethical
standards.
Conditional Training: Albert and Peter
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.
Schedules of Reinforcement

Immediate Reinforcers To our detriment, small but immediate
reinforcements are sometimes more alluring than big, but delayed reinforcements
Continuous Reinforcement reinforcing the desired response each time it occurs
Learning occurs rapidly, but rapid extinction. This is the best way master behavior.
Partial (Intermittent) Reinforcement reinforcing a response only part of the time results in slower acquisition greater resistance to extinction Hope springs

Updating Skinner’s Understanding
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.
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.
