Q

At what stage of sleep does systems-consolidation occur?

A

Short wave sleep (SWS)

45
Q

What are the stages of systems consolidation hypothesis (SCH)?

A

What kind of memories does SWS prefer?

A

Memories with relevance for future plans

47
Q

Explicit

Conscious

48
Q

Is there evidence for SWS playing a causal role in memory consolidation?

A

Yes

49

What is an example of dual processes of cognition

A

Explicit and implicit thinking

50
Q

How many studies are there to provide support for the role of sleep in systems consolidation?

A

2

51
Q

Atizena & Cantero (SCH Study 1)

What were participants required to do?

A

Exposure to either emotional/non emotional images

Half pps were sleep deprived, control slept at home

52
Q

Atizena & Cantero (SCH Study 1)

What were the findings?

A

EMOTIONAL images gained preference during encoding

Sleep deprivation = memory impairment

53
Q

Atizena & Cantero (SCH Study 1)

What happened in the test phase, after 1 week?

A

Pps asked to classify pics as ‘know’ or ‘remember’

More likely to ‘remember’ if they had slept normally

54
Q

Rasch (SCH study 2)

What were the participants require dot do?

A

Learned location of pairs of cards while exposed to scent of roses

Rasch (SCH study 2)

Rasch (SCH study 2)

What was the effect if the participants were exposed to the scent whilst awake?

A

No effect

57
Q

What is the multiple trace theory?

A

The idea that links with the hippocampus are maintained

58
Q

In the multiple trace theory, what is stored in the neocortex?

A

The facts of an episode are extracted and stored in the neocortex

59
Q

What is the main difference between the two-step model and the multiple trace theory?
