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

24
Reinforcer
Any event that strengthens the behavior it follows
25
Positive reinforcement
Increasing behaviors by presenting a positive stimuli
26
Negative reinforcement
Increasing behaviors by stopping or reducing negative stimuli Takes a way an unwanted stimulus
27
Primary reinforcer
Innately reinforcing stimulus (such as one that satisfies a biological need)
28
Conditioned reinforcers (secondary reinforcers)
Stimulus that gains its reinforcing power through its association with a primary reinforcer
29
Continuous reinforcement
Reinforcing the desired response every time it occurs
30
Partial (intermittent) reinforcement
Reinforcing a response only part of the time Results in slower acquisition but creates resistance to extrinction
31
Fixed-ratio schedule
Reinforcement schedule that reinforcers a response only after a specified number of responses
32
Variable-ratio schedule
Reinforcement schedule that reinforces a response after an unpredictable number of responses
33
Fixed-interval schedule
Reinforces a response only after a specified time has elapsed
34
Variable-interval schedule
Reinforces a response at unpredictable time intervals
35
Punishment
An event that decreases the behavior that it follows
36
Cognitive map
Mental representation of the layout of one's environment
37
Latent learning
Learning that occurs but is not apparent until there is an incentive to demonstrate it
38
Intrinsic motivation
Desire to perform a behavior for its own sake
39
Extrinsic motivation
Desire to perform a behavior due to promised rewards or threats of punishment
40
Observational learning
Learning by observing others No shit.
41
Modeling
Process of observing and imitating a specific behavior
42
Mirror neurons
Frontal lobe neurons that fire when performing certain actions or when observing another doing so
43
Prosocial behavior
Positive, constructive, helpful behavior
44
Memory
Persistence of learning over time through the storage and retrieval of information
45
Flashbulb memory
Clear memory of an emotionally significant moment or event
46
Encoding
Processing of information into the memory system
47
Storage
Retention of encoded information over time
48
Retrieval
Process of getting information out of memory storage
49
Sensory memory
Immediate, very brief recording of sensory information in the memory system
50
Short-term memory
Activated memory that holds a few items briefly (a few seconds)
51
Long-term memory
Relatively permanent and limitless storehouse of the memory system; knowledge, skills, and experiences
52
Working memory
Newer understanding of short-term memory that involves conscious, active processing of incoming auditory and visual-spatial info, and of information retrieved from long-term memory
53
Rehearsal
Conscious repetition of info
54
Spacing effect
Tendency for distributed study or practice to yield better long-term retention than is achieved through massed study or practice
55
Serial position effect
Our tendency to recall best the last and first items in a list
56
Visual encoding
Encoding of picture images
57
Acoustic encoding
Encoding of sound
58
Semantic encoding
Encoding of meaning
59
Imagery
Mental pictures; powerful aid in effortful processing

Chunking
(Often automatically) organizing items into familiar, manageable units
63

73
Relearning
Memory measure that assesses the amount of time saved when learning material for a second time
