Q

shaping

A

an operant conditioning procedure in which reinforcers guide behavior toward closer and closer approximations of the desired behavior

31
Q

discriminative stimulus

A

a stimulus that elicits a response after association with reinforcement

32
Q

positive reinforcement

A

increasing behaviors by presenting positive reinforcers

33
Q

positive reinforcers

A

any stimulus that when presented after a response strengthens the response

34
Q

negative reinforcement

A

increasing behaviors by stopping or reducing aversive stimuli

35
Q

negative reinforcer

A

any stimulus that when removed after a behavior, strengthens the behavior
-wearing seatbelt removes/ends loud beeping noise

36
Q

primary reinforcer

A

an innately reinforcing stimulus, such as one that satisfies a biological need

37
Q

conditioned/secondary reinforcer

A

a stimulus that gains its reinforcing power through its association with a primary reinforcer

38
Q

reinforcement schedule

A

a pattern that defines how often a desired response will be reinforced

39
Q

continuous reinforcement schedule

A

reinforcing the desired response every time it occurs

40
Q

partial (intermittent) reinforcement schedule

A

reinforcing a response only part of the time
-results in slower acquisition of response but has far greater resistance to extinction

41
Q

fixed-ratio schedule

A

reinforces a response after a specific number of responses

42
Q

variable-ratio schedule

A

reinforces a response after an unpredictable number of responses

43
Q

fixed interval schedule

A

reinforces a response only after a specified time has elapsed

44
Q

variable interval schedule

A

reinforces a response at unpredictable time intervals

45
Q

punishment

A

an event that tends to decrease behavior that it follows

46
Q

positive punishment

A

administers an aversive stimulus
-spraying water on a barking dog

47
Q

negative punishment

A

withdraw a rewarding stimulus
-taking away a misbehaving teen’s phone privileges

48
Q

biofeedback

A

a system for electronically recording, amplifying, and feeding back information regard a subtle physiological state such as blood pressure or muscle tension

49
Q

preparedness

A

a biological predisposition to learn associations such as between taste an nausea that have survival value

50
Q

John garcia

A

-challenged the idea that all associations can be learned well
-studied taste aversion

51
Q

instinctive drift

A

the tendency of learned behavior to gradually revert to biologically predisposed patterns

52
Q

taste aversion

A

-the learned behavior to avoid a food based on a negative experience
-can be learned over time or come from a single stimulus

53
Q

cognitive map

A

a mental representation of the layout of one’s environment

54
Q

insight

A

-a sudden realization of a problem’s solution
-contrasts with strategy based solutions

55
Q

latent learning

A

learning that occurs but is not apparent until there’s an incentive to demonstrate it

56
Q

there is more to learning than associating…

A

a response with a consequence, there’s also cognition

57
Q

A

a desire to perform a behavior to receive promised rewards or avoid threatened punishment

A

attempting to alleviate stress directly by changing the stressor or the way we interact with that stressor

60
Q

emotion focused coping

A

attempting to alleviate stress by avoiding or ignoring a stressor and attending to emotional need related to our stress reaction

61
Q

personal control

A

our sense of controlling our environment rather than feeling helpless

Q

learned helplessness

A

the hopelessness and passive resignation an animal/person learns when unable to avoid repeated aversive events
-when efforts consistently fail to bring rewards and if this persists, the subject will stop trying

63
Q

biological influences on classical conditioning

A

natural predispositions constrain what stimuli and responses can be easily associated

64
Q

biological influences on operant conditioning

A

-unnatural behaviors instinctively drift back toward natural ones
