| summary | The early discovery of neuronal representations in the brain, such as edge-sensitive cells in the visual cortex, has led to the view of the brain as an information-processing system. Thus the perception sciences community usually assumes that perception is a hierarchy of computations performed on increasingly abstract representations of the stimulus. Without these representations, achievement of perceptions of the kind one ordinarily experiences would be, presumably, impossible.
Nonetheless, some current counterflow theories argue for an alternative view in which perceptual processes detect invariants in the structure of the stimuli (e.g. physical or sensorimotor invariants). In this view, reminiscent of Gibson's ecological theory, perception is regarded as a non-representational system. In other words, perception would be a sort of (invariants) direct apprehension system.
An interesting issue is whether the debate between representationalists and neo-Gibsonians at the subpersonal level is linked to an analogous debate in the philosophy of perception, namely whether perception should be conceived as a representation of, or as a relation to, the world. One question is whether direct realism can be reconcilied with the view of the brain as a system manipulating representations.
These debates about the relevance of the notion of representation are reflected in many domains of cognitive sciences, namely in psychology (e.g. sensorimotor theory), analytical philosophy (e.g., direct realism), but also computational modeling, etc... The purpose of this workshop is to shed different lights on this problem, through interventions of speakers with pluridisciplinary backgrounds but similar interest in this fundamental aspect of perception research. |
