Q

Q

classical conditioning

A

occurs when a neutral stimulus paired with a previously meaningful stimulus, eventually takes on some meaning itself

Q

spontaneous recovery

A

original response disappears on its own, but then is elicited again by the previous CS at later time

21
Q

second-order conditioning

A

a previous CS is used as the US; changing the CS and reconditioning

22
Q

contiguity approach

A

Pavlov and Watson believed that the pairing of the neutral and natural stimuli occurred because they were paired in time

23
Q

contingency approach

A

Robert Rescorla believes that the CS and US get paired because the CS comes to predict the US

24
Q

operant conditioning

A

an organism’s learning to make a response in order to obtain a reward or avoid punishment
pioneered by BF Skinner

25
Q

thorndike’s law of effect

A

states that a behavior is more likely to recur if reinforced

26
Q

shaping

A

conditioning, differential reinforcement of successive approximations

27
Q

primary reinforcement

A

you don’t have to learn to like it, you already now you like it and it reinforces behavior (i.e. food)

28
Q

secondary reinforcement

A

learned reinforcers, you learn its benefits (i.e. money)

29
Q

positive reinforcement

A

reward or event that increases the likelihood that a particular type of response will be repeated (i.e. candy)

30
Q

negative reinforcement

A

the removal of an aversive event to encourage behavior (i.e. seatbelt sign beeper)

31
Q

omission training

A

seeks to decrease the frequency of behavior by withholding the reward until the desired behavior is demonstrated

32
Q

schedule of reinforcement

A

the frequency with which an organism receives reinforcement for a given type of response

33
Q

continuous reinforcement schedule

A

every correct response that is emitted results in a reward, producing rapid learning, but also rapid extinction

34
Q

partial reinforcement schedule

A

schedule of reinforcement where not all responses are reinforced

35
Q

fixed-ratio schedule

A

the reward always occurs after a fixed number of responses, produce strong learning, but learning extinction happens quickly

36
Q

variable-ratio schedule

A

ratio of responses to reinforcement is variable and unpredictable, reinforcement can come at any time (i.e. slot machines)

37
Q

fixed-interval schedule

A

reinforcement is presented as a function of fixed periods of time, as long as there is at least one response (i.e. salary)

38
Q

variable-interval schedule

A

reinforcement is presented at differing time intervals, as long as there is at least one response

39
Q

reinforcement vs. punishment

A

reinforcement increases behavior and punishment decreases it

40
Q

positive punishment

A

involves the application, or pairing of a negative stimulus with the behavior (i.e. do 20 pushups for talking back)

41
Q

negative punishment

A

involves the removal of a reinforcing stimulus after the behavior has occurred (i.e. losing tv privileges)

42
Q

escape

A

type of operant learning, an individual learns how to get away from an aversive stimulus by engaging in a particular behavior (i.e. if a child doesn’t want to do something and has a tantrum, if they get what they want they will still keep using tantrums)

43
Q

avoidance

A

occurs when a person performs a behavior to ensure an aversive stimulus is not presented (i.e. the child doesn’t want to eat what’s for dinner so they pretend they’re sick to get soda and crackers)

44
Q

learned helplessness

A

occurs when consistent efforts fail to bring rewards; if the situation persists, the subject will stop trying

45
Q

social learning/observational learning

A

learning based on observing the behavior of others as well as the consequences of that behavior

46
Q

Albert Bandura’s Bobo Doll Experiment

A

the children followed what they saw, how the adults played with the doll the children did the same
conclusion: four conditions must be met for observational learning to occur: the learner must pay attention to the behavior in question, there must be retention of the observed behavior, there must be a motivation for the learner to produce the behavior at a latter time, and the potential for reproduction of the behavior must exist

47
Q

social and emotional learning

A

programs designed to help develop empathy and conflict resolution in students

48
Q

garcia effect

A

John Garcia demonstrated that animals that eat a food that results in nausea induced by a drug or radiation will not eat that food if they ever encounter it again
