4
Q

perceptual anticipation theory …

A

the perceptual anticipation their argues that visual perception and visual imagery depend on the same visual buffer

5
Q

imagery resembles perception: evidence of facilitation …

A

Participants were told to perceive or imagine a green or red horizontal grating

one eye was then presented with a green gating and the other a red grating

these two different stimuli presented caused binocular rivalry to occur…

the stimulus consciously perceived was more likely the one they had imagined

the degree of orientation had an effect

6
Q

evidence of interference

imagery resembles perception

A

dual task experiment

participants rated vividness of auditory or visual images

the secondary task was either visuo-spatial or to do with the phonological loop

the spatial task reduced the vividness of the visual imagery

clouting task (phonological) reduced the vividness of the auditory imagery

7
Q

evidence for mental imagery

A

Pavio sugastes there was dual coding in mental imagery

a code for visual representations and a code for verbal representations

  • recall better sets of concrete imageable words better than concrete non-imageable words
8
Q

mental rotation evidence

A

time taken to mentally rotate an image is the same as it would take to move it through space

when deciding whether two objects that are mirror images of each other are the same, the time to make the decision in related to the degree of rotation

9
Q

neuroimaging evidence that imagery and perception are similar

A

viewing an object and imaging one both activate the primary visual cortex

when imaging an object however there is greater activation in the posterior left cortex

10
Q

children’s and adults use of imagery

A

young children are more likely to reply on imagery as long term memory knowledge is lacking

11
Q

Kosslyn 1979, Adult and children’s imagery use

A

participants (5,14 and adults) had to make judgements about animal properties

there were two conditions,, first the participant had were asked to visualise the animal and then indenity properties and then in another they only identified properties

15
Q

Imagery and Social anxiety experiment

A

Hirsch et al 2003

asked participants to imagine themselves conversing with another person

then asked them to imagine a positive image of themselves conversing with another person

results of self-reported rating showed reduced distress in the positive imagery condition

16
Q

desensitisation treatment

A

imagining the feared object until their anxiety diminishes

17
Q

positive imagery training

A

can be used to treat depression, it uses a computerised program, training participants to produce positive imagery about the future in order til improve their mood
