Q

what is the sensory store in the multi-store model and what are the two types of information it takes in?

A

it is a store of sensory information. iconic memory is for visual information and the echoic is for auditory information.

Q

what is the phonological similarity effect (Conrad, 1964)?

A

Recall is 25% worse with a phonologically similar list compared with dissimilar list. this suggests speech based rehearsal processes within the phonological loop.

26
Q

what is the primary visual cortex for

A

Sight

27
Q

what is consciousness level

A

scale of awareness from zero contents to fully aware

28
Q

what is consciousness content

A

moment to moment here and now

29
Q

who is responsible for the study into context dependent remembering

A

Godden and Baddeley (1975)

30
Q

what are the results of Godden and Baddeley (1975)

A

lists of words learned underwater are remembered better underwater and vise versa

31
Q

what was the study done by Loftus and Palmer (1974)

A

participants watched videos of car crashes. and were asked ‘how fast were the cars going when they ‘smashed’ ‘crashed’ ‘bumped’ into each other. it was found that depending on what word was used the speeds were different. recollection of the aftermath was affected as well

32
Q

what is proactive interference

A

Old memories interfere with ability to remember new memories

33
Q

what is retroactive interference

A

new memories interfere with the ability to remember old memories

34
Q

what are the three main processes in language production

A

conceptualisation, formulation and articulation.

35
Q

what did Gestalt psychologists suggest

A

they suggested that perception does not happen by breaking down into parts but by considering the whole experience

36
Q

what does Gestalt mean in German

A

Whole

37
Q

what are the laws of perception in Gestald psychology?

A 
law of proximity
law of similarity
law of closure
law of good continuation
law of common fate
law of pragnanz (law of simplicity)
38
Q

what are the two main theories in object recognition

A

image based models and structural based models

39
Q

what is the image based models theory in object recognition?

A

specific views of objects are ‘stored’ and recognition performance is based on generalisations from these

40
Q

what is the recognition by component theory

A

objects are represented using basic shape units called Geons

41
Q

what are Geons in object recognition

A

Geons are defined by variations in a small number of basic parameters called Non-accidental properties

42
Q

what is the most recognisable view in 3d object categorisation

A

the canonical view

43
Q

in the experiment by Palmer, Rosch and Chase (1981) what did they find

A

the rating of the view of an object from best to worst correlated with the reaction time to recognise it

44
Q

why is the canonical view the best view

A 
frequency hypothesis (it is the view we see most in our life)
maximal information hypothesis (it provides the most amount of information)
45
Q

what is the Featural hypothesis of face recognition

A

the Featural hypothesis suggests that faces are primarily remembered due to their facial features.

46
Q

what is the Configural hypothesis of face recognition

A

the Configural hypothesis places the importance into the relationship between the spacing of facial features.

47
Q

what is the Holisitc hypothesis of facial recognition

A

the Holisistic hypothesis takes the face as a perceptual whole where both featural and configural information are required for accurate recognition

48
Q

how does fMRI scans provide support for faces being special

A

one area of the brain activates for faces and another activates for objects

49
Q

what is agnosia

A

refers to the inability to recognise people or objects even when basic sensory modalities are intact

50
Q

what are the two visual processing streams

A

Dorsal system (involved in object localisation) and the ventrical system (involved in object identification)

51
Q

what are the two classes of illusions

A

Bottom-up (physiological) and Top-down (cognitive)

52
Q

what is serial and what is parallel information flow

A

Serial is piecemeal processing, bottleneck and sequential. Parallel is bulk processing and consecutive

53
Q

what are the key points of the case study of HM

A

Became an amnesiac due to a bilateral removal in the hippocampal zone to try and fix epilepsy.
Can remember child memories
Memory generally poor for events after operations

54
Q

what are the key points of the case study of Clive Wearing

A

british music conductor. Herpes virus attached CNS damaging the hippocamous.
Acute and long-lasting case of anterograde and retrograde amnesia, meaning that he lacks both the ability to form new memories and to recall some aspects of his past memories.
Has no knowledge of ever learning music but can still play the piano

55
Q

what is Korsakoff syndrome

A

Alcohol related problem in metabolizing the vitamin thiamine, which leads to brain damage in areas of the hippocampus and diencephalon, resulting in loss of episodic memory

56
Q

what are the problems with using patients with Korsakoff syndrome for studying amnesia

A

there is a gradual onset. there is widespread brain damage. it is inconsistent in what parts of the brain are affected.

57
Q

what is retrograde amnesia

A

inability to remember events/information before the critical incident..

58
Q

what is antegrade amnesia

A

inability to remember events/information after the critical incident.

59
Q

what is implicit memory

A

memory that cannot be consciously recalled

60
Q

what is explicit memory

A

memory that can be consciously recalled
