Q

What does HM’s case study suggest about the distinctness of memory systems?

A

As HM could create new long term procedural memories (mirror drawing task) but couldn’t remember doing so, suggests different LTM stores

Q

What is the Serial Position Effect?

A

The first items remembered (in a series) are remembered well as they are rehearsed and enter LTM, and the last items are remembered as they are held in WM. The central items are easest lost

25
Q

Define Retrieval

A

Re-accessing Information from the past, which has been encoded and stored

26
Q

How is memory theorised to be stored?

A

As a semantic network of spreading activation. The activation of a concept will prime other related concepts, with the most related concepts being primed first/ the most

27
Q

How can Chunking improve Encoding?

A

It combines items into small, meaningful untits, allowing more information to be stored at once

28
Q

How can Mnemonics enhance storage?

A

They combine information into a single word or phrase, and allow remembering through association

29
Q

How can Organisation enhance encoding?

A

By organising information semantically, eg with a visual hierarchy, information is encoded both semantically and visually

30
Q

What is the method of Loci?

A

Using a familiar (or well thought out space), information is associated with a physical location (or perception of one), so being in that location trigger the information

31
Q

What are the two types of rehearsal?

A

Shallow rehearsal and Elaborate Rehearsal

32
Q

What type of rehersal is shallow (maintanance)

A

Reading, or rereading information

33
Q

Give an example of elaborate rehearsal

A

Turning your revision notes into flashcards, a new format.

34
Q

What did Craig and Lockhart (1972) theorise about levels of processing?

A

Multiple levels, structural, phonemic and semantic

35
Q

Which type of processing is the most shallow? (Craig and Lockhart, 1972)?

A

Structural, Processing shapes as letters, letters as a combination to make a word?

36
Q

What level of processing is phonemic? (Craig and Lockhart, 1972)

A

The middle, Deeper. “Horse rhymes with course?”

37
Q

What is the deepest level of processing? (Crag and Lockhart, 1972)

A

Semantic, understanding of a meaning of a word for example

38
Q

What factors can influence the ease of retrieval of memory?

A

Nature of stimulus, as well as environmental. physiological and psychological factors

39
Q

What factors about the stimulus might influence retrieval?

A

Distinctiveness of event (or behaviour witnessed etc)

Also distinctive cues used to retrieve the memory

40
Q

How might environmental context affect memory?

A

if you are in a similar environment to where you learnt information

41
Q

What were the results of Goddon and Baddeley (1975)

A

Divers who learnt underwater performed better underwater and vice versa

42
Q

What is a flashbulb memory?

A

a memory of an event that happens a single time or rarely, yet is remembered clearly.

43
Q

What did Talacario and Rubin find in 2003?

A

They found that participants were more confident and remembered more details about 9/11 than typical college events

44
Q

How does the role of pre-existing knowledge affect retrieval of memory?

A

Prior knowledge allows for a pre-existing schema for information to slot in

45
Q

What is schema consistent information?

A

information that fits well into preconceived ideas, eg a bank robber having a gun

46
Q

What did Tuckey and Brewer (2003) find about schema inconsistent information?

A

when showing participants a bank robbery both the schema consistent and inconsistent information

47
Q

Why might memory failures occur with sensory memory?

A

memory is lost if attention is not paid

48
Q

Why might memories be lost from stm?

A

If the memory is not rehearsed

49
Q

What is Retroactive interference?

A

Where new information interferes with the old

50
Q

What is proactive interference?

A

Where old information interferes with the new

51
Q

What is tip-of-the-tongue phenomenon?

A

A temporary inability to recall information, can often recall similar sounds or meanings

52
Q

What is a lapse in attention?

A

A memory failure that normally happens while multitasking, the less ‘difficult’ task is often not encoded properly

53
Q

What is egocentric bias?

A

distortion of memory that makes you look better. E.g. remembering your A grades but not your D grades

54
Q

What is misattribution?

A

assigning a recollection or idea to the wrong source.

55
Q

Give an Example of Misattribution

A

witnessing an event, seeing a face later on, and incorrectly assigning the faces to the event

56
Q

What is consistency bias?

A

altering the past to fit the present

57
Q

What did Marcus (1986) find about consistency bias?

A

Asked to rate views on controversial issues in 1973. Asked in 1982 to rate again, then say what they said in 73
Their memories of their ratings were closer to the 82 ratings than they were to the originals

58
Q

What did Loftus and Palmer (1974) find about misleading information?

A

Loftus and Palmer(1974)
Smashed—40.5 mph, Hit—34mph
Was there glass? Smashed = yes, contacted = no

59
Q

What is infantile amnesia?

A

Children age 5-10 can often remember events from before they were 1. Why? Immature encoding areas of brain? Lack of language/self concept?

60
Q

What is alzheimers?

A

Progressive brain disease, impaired LTM and STM. Spreads from temporal lobe incl. hippocampus, to frontal lobe and other areas.

61
Q

What is change bias?

A

Exaggerating differences, consistent rating for relationships over the years, yet love has consistently ‘increased’

62
Q

What did Loftus find about false memories?

A

If people were told about a false memory of being lost in the mall, they began to remember it.
