Learning

relatively permanent change in behavior that is brought by experience

Habituation

decrease in response to stimulus after repeated exposure. ignore things that have stopped providing new info

• dog salivation

• classical conditioning

classical conditioning

neutral stimulus produces involuntary response

neutral stimulus

stimulus that does not naturally produce an interested response before conditioning

unconditioned stimulus (USC)

stimulus that produces a natural response, does not need to learn

unconditioned response (UCR)

natural and automatic response (no training)

conditioned stimulus (CS)

before neutral stimulus paired w USC to form response

conditioned response (CR)

after conditioning, brought from CS

conditioned

learned

unconditioned

not learned

phobias

intense & irrational fears

true or false: racism may be sustained thru classical conditioning

true (exposure to certain news w minority groups w danger = development of negative attitudes)

extinction

old conditioned response decreases then disappears

spontaneous recovery

Reemergence of extinguished conditioned response after time w no conditioning (relapse)

stimulus generalization

conditioned stimulus with a similar stimulus produce same response (similarities)

stimulus discrimination

2 stimuli are different from eo, one brings response while the other does not (difference) - adaptive behavior

true or false: learners develop an understanding when an unconditioned stimuli is paired w CS

true

Operant conditioning

voluntary response is strengthened or weakened from response’s consequences (do more often, produce desirable outcome)

Law of effect

• thorndike

• individual would make direct connection between stimulus and response over time

reinforcement

• skinner

• stimulus increases probability of behavior being repeated

reinforcer

stimulus that increases the probability that behavior will repeat

primary reinforcer

secondary reinforcer
