Q

Variable - Ratio (VR) schedule

A

Reinforce behavior after a varying number of performances, but such that the average number of performances to receive a reward is relatively constant
- Reward after 2 button presses, then 8, 6, 4
- Best for learning new behaviors

26
Q

Automatic Processing

A

Info gained without effort
- Unintentional
- Passively absorbed

27
Q

Elaborative encoding

A

Encode by linking to knowledge in memory

28
Q

Semantic encoding

A

Encode by meaningful context
- Strongest form

29
Q

Self-reference Effect

A

Recall info best when we put it into the context of our own lives

30
Q

Maintenance Rehearsal

A

Repetition of a piece of info to keep it within working memory or store

31
Q

Method of loci

A

Associating each item in a list with a location along a route through a building that has already been memorized
- carton of eggs on doorstep, butter in living room

32
Q

Peg-word system

A

Associated numbers with items that rhyme with or resemble the numbers
- One and sun, three ans tree

33
Q

Chunking (clustering)

A

Taking individual elements of a large list and grouping them together into groups of elements with related meaning

34
Q

Sensory Memory

A

Preserves info in its original sensory form
- Iconic (visual stimuli)
- Echoic (auditory stimuli)

35
Q

Short-term memory

A

Fades quickly without rehearsal
- Memory capacity: 7 + or - 2 rule

36
Q

Working Memory

A

Enables us to keep info in consciousness simultaneously and to manipulate that info

37
Q

Long-term Memory

A

Essentially limitless warehouse for knowledge that we are then able to recall on demand

38
Q

Elaborative rehearsal

A

Association of the info to knowledge already stored in long-term memory

39
Q

A

Skills, habits, and conditioned responses

40
Q

Procedural memory

A

Unconscious memory of the skills required to complete procedural tasks

41
Q

Priming

A

Presentation of one stimuls affects perception of a second

Q

Explicit memory (declarative)

A

Memories that require conscious recall

43
Q

Episodic memory

A

Collection of life experiences

44
Q

Semantic memory

A

Ideas, concepts, or facts that we know, but are not tied to specific life experiences

A

Process of demonstrating that something has been learned and retained

46
Q

Recall

A

retrieval and statement of previously learned info

47
Q

Spacing effect

A

Longer the amount of time between sessions of relearning, the greater the retention over time

48
Q

A

concepts are linked together based on similar meaning

49
Q

Context effect

A

Memory is aided by being in the physical location where encoding took place

50
Q

Source monitoring

A

Involves determining the origin of memories, and whether they are factual or fictional

51
Q

State-dependent memory

A

Performing better when in the same mental state as when info was learned

52
Q

Serial position effect

A

Item’s position in a list of affects particpant’s ability to recall

53
Q

Primacy/recency

A

Tendency to remember early and late items in a list

Amnesia

A

Significant loss of memorized info

55

Source amnesia

A

Inability to remember where, when, or how one has obtained knowledge

56
Q

A

Degenerative brain disorder thought to be linked to a loss of acetylcholine in neurons that link to the hippocampus

57
Q

Korsakoff’s syndrome

A

Memory loss caused by thiamine deficiency

58
Q

Confabulation

A

Process of creating vivid, but fabricated memories

59
Q

Agnosia

A

Inability to recognize objects, people, or sounds

60
Q

Interference

A

Retrieval error caused by the existence of other, usually similar, information

61
Q

Proactive interference

A

Old info interferes with new learning

62
Q

Retroactive interference

A

New info causes forgetting of old info

63
Q

A

Theory of memory recall in which cognitive processes affect the act of remembering

64
Q

Intrusion errors

A

False memories that have included a false detail into a particular memory

65
Q

Neuroplasticity

A

Change in neural connections caused by learning or a response to injury

66
Q

67
Q
