Q

Day dreaming is the SAME as midn wandering (T/F)

Q

One way to categorise mind wandering is temporality, MOSTLY we think about ______

Q

Sleep is a loss of consciousness

Q

Deep sleep = no cosnciousness

23
Q

How are spontaneous experiences measured subjectively?

A

‘just ask’ - restrospectively ‘were you paying attention THEN’?
Self caught // probe caught

24
Q

advantage of retrospective inquiry of spontaneous experience is

A

Person can FINISH the task they’re doing without interference and then you ask –> ecologically valid

25
Q

Probe caught MW may be better than self-caught, WHY?

A

Sometimes we are not aware that we engage in MW = we will NOT report it immediately or restrospectively

26
Q

Serial experience sampling is________

A

way of studying sleep, waking up person consecutively

27
Q

When we consume alcohol, the amount of MW that you can self recall___________

A

Amount of MW that you CAN self-recall decreases

=become less self aware and is better detected by probe

28
Q

The major issue of ‘just ask’ methodology is_______

A

How OFTEN do we ask? Agreed that about 1min ish –

29
Q

We usually have good awareness of our own perforamnce in different states

A

FALSE - will day with/out alcoh is the SAME but objectively is worse

30
Q

Objective measures of mind wandering are______

A

Reaction time;
eye movements
other physiological measures

31
Q

‘dream catching’ is a process of

A

Waking people that are in the lightest part of sleep (just drifting off) and asking what they were dreaming about

32
Q

There is a way we can decode the contents and onset of dreaming (T/F)

A

TRUE - matching MRI brain waves with X objects / scenes = able to PREDICT what person was dreaming about

33
Q

The DISADVANTAGE of dream catching is_______

A

it requires a long time, + data is NOT transferrable to other people

34
Q

Ocular recording can infer alertness state from the _________

A

Pattern of movement in reading how they move from words

35
Q

MW can be inferred from a reading task when________

A

We see that fixation is skewed on separated words, is BIDIRECTIONAL,

36
Q

In a waking state we can make smooth pursuit eye movements, if conscious and asked to imagine following a fly smoothly in a figure 8, we will not be able to do so

A

TRUE - imagination of following object smoothly is not possible while awake

37
Q

How do we know we can trust dream reports?

A

Smooth pursuit = valid, shows that subject is in a state that is very similar to actually looking at a real target (opposed to an imagined one)

38
Q

Imagination and dreams are synonymous in their relationship to perception

A

WRONG - dreaming is much closer to actual perception than imagination

39
Q

REM sleep behaviours __________ remembered

A

ARE remembered, can recall dreams

40
Q

Sleep paralysis is when ___________ and was first described as _______sensation

A

You are AWAKE but can’t move, sensation of demon on your chest preventing you from moving

41
Q

MW can be manipulated by_______

A

changing DIFFICULTY
STRESS
MOTIVATION

42
Q

Increasing difficulty // stress will result in _______MW

A

MORE MW

43
Q

In a veyr easy task, you will have _______MW compared to a hard task

A

EASY- intentional mind wandering

HARD - unintentional mind wandering

44
Q

Sleeping can be maipulated by__________

A

Applying electrical stimulation to the PFC = incr awareness in dreaming
nutritional techniques

45
Q

According to IIT, the baseline of conc is

A

SWS - where the brain is ENTIRELY in sync rather than region dependent and discrimination of inf is disabled

46
Q

The major NT associated with sleep are __________

A

acetylcholine and norepipnepherine

47
Q

Acetyl choline is important for ______and is present in_________

A

learning, memory, WAKE/REM

48
Q

Norepinepherine is used for _______and present in _______

A

arousal, attention

ABSENT in sleep

49
Q

We are ‘conscious’ in REM and therefore the PFC is active

A

FALSE - PFC is inactive bc in deep sleep

50
Q

The amygdala is MOST active during

A

night - REM

51
Q

Dreaming often associated with _____ region

A

POSTERIOR region

52
Q

Which area has been implicated in causing dreams?

A

BRAINTSTEM turns on dreaming cortex

53
Q

MW is associated with __________amplitude of objective measures

A

REDUC AMP

54
Q

Local sleep is when _________ and may indicate that ______ are related

A

When one area of the brain falls asleep

May show that day dreaming / night dreaming share neural correlates

55
Q

Mind wandering is BEST characterised by_______

A

decoupling from the environment
