Classical and operant continue
Generalization
Responding (salivation) to a new tone that is slightly different. Adaptive function:
Animal responds to similar tones in rustling leaves or would be eaten. Doesn’t
have to be identical.
Discrimination
Loss of generalization. Learn to respond to only one tone. Afraid of German
Shepard's only not wiener dogs.
Extinction processes or new conditioning can help change unwanted
responses to stimuli.
Exposure therapy or systematic desensitization therapy combat
psychological disorders using classical conditioning principles.
Recovery:
Former drug users crave the drug when...
They are in the environment in which they took drugs.
They associate with people with whom they took drugs.
These contexts act as CSs and trigger cravings for the drug (CR).
Little Albert Experiments
John Watson applied the principles of classical conditioning to humans.
Watson believed that human emotions and behaviors are merely a
bundle of conditioned responses (conditioned emotional reactions or
CERs).
Watson and a colleague, Raynor, conditioned a baby to associate
white rats (CS) with a loud noise (US) and fear them (CR).
Lil A showed stimulus generalization, but positive emotions could
also become associated.
