Q

Procedural memory

A

Knowledge of skills- once you know how to do you wont think about the steps to do it anymore

40
Q

Supporting evidence for separate components of LTM

A

Clive Wearing- only remember skills such as piano but couldn’t remember being able to- episodic
HM- hippocampus removed- could learn new skills but not create new memories- procedural uneffected- cerebellum was undamaged
- different stores interact with one another

41

Creation of procedural memories

42

A

Controls learning and memory

43

A

Spatial and verbal

46

Supports the idea that we do not have to rehearse everything with the verbal rehearsal

47
Q

Weaknesses of wmm?

Baddeley experiment is experimental and doesn’t show how memory works with real life tasks
Functions of central executive are hard to test and vague
Only focuses upon the STM

48

Baddeley (1996) aim?

A

To find out if the LTM encodes acoustically or semantically

49
Q

IV of baddeley 1966?

A

1)acoustically similar or dissimilar word list
2)semantically similar or dissimilar wordlist
3)performance before 20 min delay and performance after

50
Q

How are IV 1 and 2 tested in Baddeley 1966? IV3?

A

Independent group design- IV 3 repeated measures

51
Q

DV of Baddeley 1966?

A

Score on a recall test of 10 words being recalled in the same order

52
Q

Why are Baddeley’s experiments significant?

A

. Shows how scientific research can be improved
. Supports cognitive approach
. Use of extracting extraneous variables
. Importance of experimental designs as it uses 2 types

53
Q

What was different about Baddeley’s first two attempt?

A

He realized the STM was helping the LTM as two stores were working together so he added the interference task and instead used a tape recording

54
Q

Sample of Baddeley 1966

A

Men and women from Baddeley’s Uni
Volunteers
72 ppts
15- acoustically similar
16- semantically similar

55
Q

How many trials in Baddeley?

A

4

56
Q

How many words were presented and for how long?

A

10 words on a slideshow- 3 seconds

57
Q

What happened between each trial in Baddeley?

A

Ppts get a 15 min interference task of writing down 8 numbers 3 times

58
Q

What did ppts have to remember in baddeley?

A

Word order as words were on signs around the room

59
Q

What was the final trial of baddeley?

A

An unexpected surprise trial- 5

60
Q

Acoustically similar?

A

Similar sound

61
Q

Semantically similar?

A

Similar meaning

62
Q

How did ppts manage with acoustically similar words?

A

Ppts found the words confusing at first but began to catch up. Control group overtakes- LTM is not confused by acoustic similarities

63
Q

Semantically similar results?

A

Confusing and the experimental group lags behind and never catches up, even to the acoustic. Little forgetting takes place but scores were lower

64
Q

conclusion of baddeley?

A

LTM encodes semantically
STM encodes acoustically

65
Q

Reliability of baddeley

A

Experiment was done correctly to ensure for reliable and and true results to apply to everyday memory. Correction of the previous 2 experiments

66
Q

Application of baddeley

A

In everyday life people are unlikely to revise word orders

67
Q

Validity of baddeley

A

Lab setting with words in an order I unreal to everyday life

68
Q

Ethicality of baddeley

A

Extremely ethical however caused doubts to people’s memory abilities

69
Q

Generalisability of baddeley

A

Study was done for both genders however there was only 15 ppts making it limited per group. All taken from a uni

70
Q

Schema inconsistent-

A

Not as easy to relate to life

71
Q

Schema consistent

A

More close relation to life

72
Q

What does Fredrick Bartlett focus on (1932)

A

Memory errors and mis-remembering

73
Q

What is memory recall based upon?

A

What we expect based on pre- existing knowledge than what actually happened

74
Q

What was Barttlets war of the ghost story study?

A

20 ppts asked to repeat the story after intervals after eating he story twice up to 2 years after

75
Q

Bartlett conclusion

A

memory is reconstructive. It is rarely accurate and prone to distortion and simplification

76
Q

What happened when ppts repeated bartletts story?

A

Odd details left out, story was shortened, items transformed into familiar details

77
Q

Contemporary study of cognitive?

A

Steyvers and hemmer (2012)

78

See how semantic memory was used to reconstruct episodic recall

Recall of naturalistic scenes and prior knowledge can contribute to curate recall in episodic memory tasks
