Q

What is elaboration in encoding mean?

A

a linking in stimulus to other information at the time of encoding.

Example is phobias are often caused by classical conditioning, and you apply that idea to your own fear by doing that you are engaging in elaboration.

Q

What did theorists originally believe about STM?

A

that the loss of info from STM was due purely to time-related decay of memory traces, but follow up research showed that interference from competing material also contributes to it.

Q

What is the third component in working memory?

also coordinates the actions of the other modules.

Q

What is the fourth component in working memory?

A

is the episodic buffer, a temporary limited capacity store that allows the various components of working memory to integrate between information and that serves as an interfere between working memory and long-term memory.

Q

What did Penfield’s research show about flashbulb memory?

A

are not as durable or accurate as we once thought.

30
Q

How many categories are their in the knowledge represented and organized in memory?

A
  1. clustering and conceptual hierarchies
  2. schemes
  3. semantic networks
  4. connections networks and parallel distributed processing (PDP) models
31
Q

What is clustering?

A

the tendency to remember similar or related items in groups.

remembered in bunches that belonged in the same category

32
Q

What is conceptual hierarchies?

A

a multilevel classification system based on common properties among items.

such as minerals then metals/stones and remembering them based on those two categories.

33
Q

What is schemas?

A

an organized cluster of knowledge about a particular object or event abstracted from previous experience with the object or event.

34
Q

What is a semantic network?

A

consists of nodes representing concepts, joined together by pathways that link related concepts.

35
Q

What is spreading activation?

A

theorists called remembering like words like butter for the word bread makes bread easier to remember.

36
Q

What is connectionist models of memory?

A

instead of how computers process memory connectionist models of memory take their inspiration from how neural networks appear to handle information.

37
Q

What is parallel distributed processing?

A

that is simultaneous processing of the same information that is spread across networks of neurons.

38
Q

What does connectionist or parallel distributed processing models assume?

A

that cognitive processes depend on patterns of activation in highly interconnected computational (relating to) networks that resemble neural networks.

39
Q

What are the four ways to retrieval?

A
  1. using cues
  2. reinstating the context of an event
  3. reconstructing memories
  4. source monitoring
40
Q

What is the tip-of-the-tongue phenomenon?

A

the temporary, inability to remember something you know, accompanied by a feeling that its just out of reach is a common experience that is typically triggered by a name that one can’t quite recall.

memories can often be jogged with retrieval cues - stimuli that help gain access to memories

41
Q

What is the misinformation effect researched by Elizabeth Loftus (1979,1992,2005)?

A

occurs when people in the research recall of an event they witnessed is altered by introducing misleading post-event information.

42
Q

What is source monitoring?

A

the process of making inference about the origins of memories.

43
Q

What is source monitoring error?

A

occurs when a memory derived from one source is misattributed to another source

44
Q

Who was the first person to conduct scientific studies on forgetting?

A

Herman Ebbinghaus

45
Q

What is nonsense syllables?

A

consonant-vowel-consonant arrangements that do not correspond to words.

46
Q

What is a forgetting curve?

A

graphs retention and forgetting over time.

47
Q

What does retention refer to?

A

the proportion of material retained(remembered)

48
Q

What is a retention interval?

A

the length of time between the presentation of materials to be remembered and the measurement of forgetting

49
Q

What is a recall measure of retention?

A

requires subjects to reproduce information on their own without any cues.

50
Q

What is a recognition measure of retention?

A

requires subjects to select previously learned information form an array of options.

51
Q

What is a relearning?

A

a measure of retention requires a subject to memorize information a second time to determine how much time or how many practice trials are saved by having learned it before.

52
Q

What are the reasons why we forget?

A
  1. ineffective encoding
  2. decay
  3. interference
  4. retrieval failure
  5. motivated forgetting
53
Q

What is a type of ineffective encoding?

A

you can’t really forget something you never learned, this is called pseudo forgetting, usually due to lack of attention.

54
Q

What is decay theory?

A

proposes that forgetting occurs because memory traces fade with time.

55
Q

What is interference theory?

A

proposes that people forget information because of competition from other material.

56
Q

What are the two different kinds of interference?

A
  1. retroactive

2. proactive

57
Q

What is retroactive interference?

A

occurs when new information impairs the retention of previously learned information

58
Q

What is proactive interference?

A

occurs when previously learned information interferes with the retention of new information.

59
Q

What is encoding specificity principle?

A

states that the value of a retrieval cue depends on how well it corresponds to the memory code.

60
Q

What is motivated forgetting?

A

It is when someone doesn’t want to remember

Freud’s term was repression

61
Q

What does repression mean?

A

to keeping distressing thoughts and feelings buried in the unconscious

62
Q

What is retrograde amnesia?

A

a person loses memory for events prior to the amnesia

63
Q

What is anterograde amnesia?

A

a person shows memory deficits for events subsequent to the onset of the amnesia

64
Q

What has studies of amnesia and other research suggest play a major role in memory?

A

the hippocampus and broader medical temporal lobe system

65
Q

These areas may play a crucial role in?

A

consolidation of memories

66
Q

What are the 2 proposed memory systems?

A
  1. declarative memory

2. nondeclarative memory

67
Q

What does declarative memory handle?

A

recall of factual information such as names, dates and events.

68
Q

What does nondeclarative memory handle?

A

recall of actions, skills, and operations. such as riding a bike or typing.

69
Q

What is semantic versus episodic memory?

A

semantic memory system contains general knowledge that is not temporally dated. and episodic memory system handles temporally dated recollections of personal experiences

70
Q

What is prospective versus retrospective memory ?

A

Prospective memory involves remembering to perform actions in the future and retrospective memory involves remembering events from the past or previously learned information.

71
Q

What is hindsight bias?

A

the tendency to reshape one’s interpretation of the past to fit with known outcomes.
