what is file though formate
representations of the world in the brain
aphantasia
Zeman et al 2015
inability to visualize things in the mind
poorly understood condition
imageless thought
francis Galton 1880
some people have no visual imagination
Charles Bonnet syndorm
Complex hallucinations of things of nature
10-40% of those with partial or severe blindness experience complex hallucinations
They are understood to be not real and are only visual in nature.
dual coding theory
Allan Paivo memory of word association abstract-concrete bad same - good concrete better with images
dual coding diagram
verbal - logogens
non-verbal - imogens
connections in dual coding diagram
There are not 2 separate systems for verbal and non-verbal information – these need to be connected but with weaker connections than those in each system.
mental representations
Shepard & Metzler 1971
2 objects same but just rotated
more rotated = longer reaction time
takes longer to mentally rotate in the head
benefits of mental representation discovery
- Was a new way to articulate functions/ abilities that were not well described before. Eg. visualising if you can rearrange the furniture in your bedroom.
- Very clear data
- No individual variation in strategy.
- No hint of ‘other factors’ needed to explain the data
file format
are representations visually in separate system?
non-depicted and depicted
non-depicted
words relational clear synatx truth very clear abstract non-spatial
depicted
images not relational no clear syntax specific spatial seeing and imagining
There is a depictive file format
when memorizing images the response is proportional to the distance
animal - rabbit/elephant/fly
end of imagery debate
fMRI evidence =
Visualising a remembered pattern uses the same brain areas (visual cortex) as actually perceiving.
Further studies confirmed linguistic areas NOT active during visual imagery.
