Q

What experiment found a 80% recall of nonsense trigrams after a 3 second interference task and 10% after 18 Seconds? What does this suggest?

A

Peterson & Peterson (1970)
That duration of STM is limited and that longer delay led to less recall as there was no chance for maintenance rehearsal.

32
Q

What is the visuospatial sketchpad?

A

Deals with and holds visual and spatial information

33
Q

What study supports Visuo-spatial sketchpad?

A

Brookes 1968 (Letter K Study)
When answering by pointing, slower due to same component/ interference

34
Q

Which study contradicts Visuo-Spatial Sketchpad?

A

Liebermen (1980)
Argues blind people have excellent spatial awareness despite having never recieved visual information

35
Q

How does the phonological loop work?

A

Holds auditory information and is rehearsed through the articulatory process

36
Q

What study supports the phonological loop?

A

Baddeley (1975)
Pts could recall more short words than long words which shows capacity is set by how long it takes to say words, not number of words

37
Q

What is the purpose of the episodic buffer?

A

To fill gap in model and acts as general storage
Brings memories together into single episodes

38
Q

What supports the theory of the episodic buffer?

A

Brain scans, appears to be in both hemispheres but particularly in hippocampus,showing memories are being transformed into ‘episodes’

39
Q

What is a weakness of the episodic buffer?

A

Little information and not understood fully

40
Q

Give 3 strengths of the working memory model

A

Naturalistic research to support (KF)
Lab research to support
Practical Applications

41
Q

Give 3 weaknesses to the working memory model

A

Contradictory evidence (Lieberman 1980)
Theoretical flaws (Oversimplified)
Lacks ecological validity

42
Q

Give similarities between MSM and Working model of memory

A

Rehearsal is important to process info
STM has limited capacity
Link between STM and LTM

43
Q

Give differences between MSM and Working model of memory

A

MSM believes STM is simple storage buffer whereas WMM believes STM is storage and workspace
MSM suggests STM is unitary whereas WMM suggests STM is more than one store

44
Q

Give three types of LTM

A

Procedural
Semantic
Episodic

45
Q

What is Semantic Memory?

A

Responsible for factual information
e.g london is the capital of England

46
Q

What is procedural memory?

A

Responsible for motor skills
e.g swimming

47
Q

What is episodic memory?

A

Responsible for remembering events
e.g 18th Birthday

48
Q

How are Procedural and Semantic Memory similar and different?

A

Procedural in cerebellum whereas semantic in Hippocampus
Procedural does not involve conscious thought, Semantic does
Both types of Long Term Memory

49
Q

How are Procedural Memory and Episodic Memory Similar and Different?

A

Procedural = unconscious whereas episodic = conscious
Knowing how vs knowing that
Have to Learn Both

50
Q

How are episodic and Semantic Memory Similar and Different?

A

Both involve conscious thought
Semanic = factual whereas episodic = experiences

51
Q

What is retroactive retrieval failure? Give examples

A

New memories interfering with old memories

Using older version of phone
Playing guitar again after learning piano
Unable to remember old password after changing to new one

52
Q

What is proactive retrieval failure? Give examples

A

Using a new phone
Remembering a friends new number after learning old
Changing routes when driving

53
Q

Give research supporting Pro/retro active interference

A

Baddeley & Hitch (1977)
Rugby players who played more games had more problems remembering games than those who missed due to injury

54
Q

Give Strengths of Retro/Proactive Interference

A

Ecological Validity
Practical Applications
Research to support (Baddeley&Hitch rugby union)

55
Q

Give weaknesses of retro/proactive Interference

A
