Document Summary
Propositional format: discrete, digital symbols, e. g. dogs chase cats = 3 symbols; each part can be introduced into different sentences, words maintain their integrity when you mix them together, e. g. 010011010001: each 0 and 1 is its own discrete digital symbol, arbitrary relation between symbols and referents (what they represent, e. g. Pictorial format: rather than being digital, they tend to be analog representations, models of the world. So are representations in the brain more propositional or pictorial: chomsky"s theory of syntax proposes that at least some representations are propositional, a series of experiments in the 1970s and 1980s challenges this theory. How not to argue that imagery is pictorial. "my mental image of joe looks like a picture of joe. The invention of behavioural neuroscience - hermann von helmholtz (1850s) Cogs 2160: this seems to be evidence that the representations in the brain have a pictorial as opposed to a propositional format.
