Computational theory of mind summary
the mind is what the brain does. It is a computer designed by natural selection. Brain engages in computation. Turing computation (?)
CTM objections (fail bc CTM doesn’t claim brain functions exactly like a laptop)
Emotionality of people. Computers crash. Parallel and distributed processes. Metaphor like steam train
CTM importance
Physicalist. Mechanisable. Reducible
How to study brain algorithms
physically fMRI Survey people Observe input output relations Consider ideal algorithms first
Evaluations of physical methods fMRI and EEG
low resolution. where ≠ how
Survey people evaluation
poor self knowledge. vague
Observe input output relations evaluation
useful eg. Baby watching folding screen proving object permanence
Consider ideal algorithms first evaluation
can be effective eg. Shape skeletons very efficient. “tap the shape anywhere” proved we are sensitive to them
Example of algorithm study methods combined
Shape rotation study. Participants self-reported rotating. Input output study show degree of rotation proportional to time taken
