Q

Learning

A

Relatively permanent change in behavior due to experience

6
Q

Behaviorism

A

View that psych

  1. Should be an objective science that
  2. Studies behavior w/o reference to mental processes

Most agree with 1 but not 2

7

11
Q

Increasing behaviors by presenting a positive stimuli

A

Increasing behaviors by stopping or reducing negative stimuli

Takes a way an unwanted stimulus

27
Q

Primary reinforcer

A

Innately reinforcing stimulus (such as one that satisfies a biological need)

28
Q

Conditioned reinforcers (secondary reinforcers)

A

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

29
Q

Continuous reinforcement

A

Reinforcing the desired response every time it occurs

30
Q

Partial (intermittent) reinforcement

A

Reinforcing a response only part of the time

Results in slower acquisition but creates resistance to extrinction

31
Q

Fixed-ratio schedule

A

Reinforcement schedule that reinforcers a response only after a specified number of responses

32
Q

Variable-ratio schedule

A

Reinforcement schedule that reinforces a response after an unpredictable number of responses

33
Q

Fixed-interval schedule

A

Reinforces a response only after a specified time has elapsed

34
Q

Variable-interval schedule

A

Reinforces a response at unpredictable time intervals

35
Q

Punishment

A

An event that decreases the behavior that it follows

36
Q

Cognitive map

A

Mental representation of the layout of one’s environment

37
Q

Latent learning

A

Learning that occurs but is not apparent until there is an incentive to demonstrate it

38
Q

Intrinsic motivation

A

Desire to perform a behavior for its own sake

39
Q

Extrinsic motivation

A

Desire to perform a behavior due to promised rewards or threats of punishment

40
Q

Observational learning

A

Learning by observing others

No shit.

41
Q

Modeling

A

Process of observing and imitating a specific behavior

42
Q

A

Frontal lobe neurons that fire when performing certain actions or when observing another doing so

43
Q

Prosocial behavior

A

Positive, constructive, helpful behavior

44
Q

Memory

A

Persistence of learning over time through the storage and retrieval of information

Q

Flashbulb memory

A

Clear memory of an emotionally significant moment or event

46
Q

Encoding

A

Processing of information into the memory system

47
Q

A

Relatively permanent and limitless storehouse of the memory system; knowledge, skills, and experiences
