Q

Results of Baddeley and Hitch’s research into interference

A

The greater number of intervening games played, the lower tje percentage of team names recalled correctly

31
Q

What theory do the results of Baddeley and Hitch’s research into interference support?

A

The interference theory as the players who played more games forgot the most amount of games

32
Q

Positive evaluation of proactive and retroactive interference: research

A

Supports explanations for forgetting

33
Q

Positive evaluation of proactive and retroactive interference: Howe’s research

A

Lab experiment meaning conditions are controlled so extraneous variables won’t effect the findings

34
Q

Positive evaluation of proactive and retroactive interference: Baddeley and Hitch’s research

A

Natural experiment shows interference can be an explanation for forgetting as the ecological validity is high

35
Q

Negative evaluation of proactive and retroactive interference: Howe’s research

A

Lab experiment meaning results may lack ecological validity which will not be representative of how we forget in everyday life

36
Q

Negative evaluation of proactive and retroactive interference: Baddeley and Hitch’s research

A

Natural experiment means extraneous variables cannot be controlled so results may not be highly reliable

37
Q

Why are cues needed for retrieval of some information?

A

Because the information is present in the LTM but cannot be retrieved without cue

38
Q

Example of use of cues (teacher)

A

Teacher who can’t remember someone’s name will ask for the first letter of it (cue) in order to remember it

39
Q

Two types of cues

A

External cues
Internal cues

40
Q

Where are external cues? With example

A

In the environment such as a smell

41
Q

What are internal cues? With example

A

Cues inside of us like an emotion or mental state

42
Q

Who carried out a study into context-dependent forgetting?

A

Godden and Baddeley

43
Q

What did Godden and Baddeley investigate in their study of context-dependent forgetting?

A

The effect of the environment on recall

44
Q

Where did Godden and Baddeley’s study of context-dependent forgetting take place?

A

Scotland

45
Q

What participants were used in Godden and Baddeley’s study of context-dependent forgetting?

A

18 divers from a diving club

46
Q

What were the divers asked to learn in Godden and Baddeley’s study of context-dependent forgetting?

A

Lists of 36 unrelated words of two or three syllables

47
Q

4 conditions in Godden and Baddeley’s study of context-dependent forgetting

A

Learn on beach recall on beach
Learn on beach recall underwater
Learn underwater recall on beach
Learn underwater recall underwater

48
Q

Mean recall score for participants who leant and recalled on beach in Godden and Baddeley’s study of context-dependent forgetting

A

13.5/36

49
Q

Mean recall score of participants who leant on the beach and recalled underwater in Godden and Baddeley’s study of context-dependent forgetting

A

8.6/36

50
Q

Mean recall score who participants who learnt underwater and recalled on the beach in Godden and Baddeley’s study of context-dependent forgetting

A

8.5/36

51
Q

Mean recall score for participants who learnt underwater and recalled underwater in Godden and Baddeley’s study of context-dependent forgetting

A

11.4/36

52
Q

What did results of Godden and Baddeley’s study of context-dependent forgetting show?

A

Context acted as a cue to recall as participants recalled more words when they learnt and recalled words in same environment

53
Q

What theory does Godden and Baddeley’s study of context-dependent forgetting support?

A

Theory of context acting as a recall cue

54
Q

When were the recall results the worst in Godden and Baddeley’s study of context-dependent forgetting?

A

When there was a change in context

55
Q

Why do findings of Godden and Baddeley’s study of context-dependent forgetting have to be treated with caution?

A

Because they don’t tell us how other people (people who aren’t divers) respond

56
Q

Research method used in Godden and Baddeley’s study of context-dependent forgetting

A

Field experiment

57
Q

Experimental design in Godden and Baddeley’s study of context-dependent forgetting

A

Independent groups

58
Q

Extraneous variables in Godden and Baddeley’s study of context-dependent forgetting

A

Possible rough weather may distress divers when they were underwater which would take their focus away fro cue/word list

59
Q

What did Abernathy find about the influence of contextual cues in a study into exam results?

A

Found that students performed better in tests if they took place in same room as they learnt the informstion

60
Q

When does state-dependent forgetting occur?

A

When your mood or physiological state during recall is different from your mood or physiological state when you were learning

61
Q

Who carried out research into state-dependent forgetting?

A

Goodwin

62
Q

Participants of Goodwin’s study into state-dependent forgetting

A

48 male medical students
