Q

Incorrect introspection is a method of explaining________and proposes______

Q

Compare attention theory and sparse view theory of peripheral vision

A

Attention - we only SEE what we attend to

Sparse view - we see much less than we think we can see

Q

Attn and conc is important because _______-

A

They may be intrinsically linked

Attn may confound conc

21
Q

Bottom up attention is only active when activated by stimulus

A

FALSE - is always active

22
Q

Directing gaze involves _________

A

Top down attention

23
Q

As the hierarchy of the VF increases (V1 –> V5), receptive fields _____

A

INCREASE + neurons also get more specific

24
Q

The VF for V4 will have a smaller receptive field than V1 (T/F)

A

FALSE - v1 will have smaller RF + less specific neurons q

25
Q

Simple cells in the LGN will fire if ___________

A

the majority of input is EXCITATORY

26
Q

Rapid vision refers to________

A

categorising objects quickly and uncosnciously i.e. snake vs face

27
Q

our ability to store info in the STM without applying conscious effort refers to _________

A

Storage of primitive info

28
Q

the major argument for consciousness being separate from attention is that __________

A

they had different neural processes, before 1990s conc was NOT measurable whereas attn was OPERATIONALISABLE.

29
Q

methods to make the stimulus invisible

A

CFS, motion induced blindness, binocular rivalry, backward masking

30
Q

Binocular rivalry is an example of methodology ____attn and ______ conc

A

WITH attention, WITHOUT consciousness

31
Q

Methods to manipulate attn incl_______

A

dual taks paradigm, innattention blindness

32
Q

Top down attention tries to _______ the sitmulus and is _______ to measure than bottom up attention

A

KEEP SAME and is EASIER to measure bc can jsut ask to direct gaze elsewhere/ diff instructions

33
Q

Consicousness without attention is apparently visible during fragile memory, this refers to______

A

being able to recall some but not all stimuli + we are CONC but not AWARE –> need to attend to sitmulus retrospectively

34
Q

The dual task paradigm operates on the assumption that attention is ________

A

FINITE

35
Q

2 tasks can be completed in the dual paradigm if one ___________

A

does not require attention = all capacity can go to doing second, more demanding task

36
Q

How is dual task and inattention blindess differe?

A

DT - trying to do BOTH tasks

IB - only given ONE instruction

37
Q

Attentional blink is different to DT because

A

AB - looking at how attention shifts from 1—> stimulus

38
Q

Some features of self-consicousness are

A

1) reflexive
2) immune to error - always referring to self
3) is action oriented - has sense of agency
4) is prioritised - better access to info about SELF

39
Q

We do not have direct unprocessed access to the outer world because of _________

A

SENSORY VEIL

40
Q

Hidden causes are called so bc

A

‘hidden’ - we dont have access to them (sens veil)

‘cause’ cause a CHANGE to our sensory organs

41
Q

prediction errors occurs when ________

A

there is inconsistency between incoming info + ou MODELLED cause

42
Q

predictive coding states that perception and behaviour need to be studied ___________

A

TOGETHER bc have a bidirectional relationship

43
Q

what role does the SELF play in predictive processing?

A

SELF is a HIDDEN CAUSE bc influences action/perception/organs

44
Q

Modelled causes are not perfect, but incoming signals are (T/F)

A

FALSE

45
Q

We can minimise prediction error and adjust our modelled cause by_______

A

Perceptual inference - moderating our THOUGHTS to match outcome
ACTIVE inference - moderating outcome behaviourally to it matches thoughts

46
Q

self consciousness can be studied by

A

intentional binding, red dot mirror task

47
Q

failing the red dot task indicates a lack of self conscience

A

FALSE - it is sufficient to demonstrate this but is not NECESSARY, may just be bored

48
Q

Neuons representing peripheral vision have ____RF

A

BIGGER RF
