A Neural Theory of Visual Attention: Bridging Cognition and Neurophysiology.

by Bundesen, Claus; Habekost, Thomas; Kyllingsbæk, Soren

from Psychological Review. 2005 Apr Vol 112(2) 291-328

A neural theory of visual attention (NTVA) is presented. NTVA is a neural interpretation of C. Bundesen’s (1990) theory of visual attention (TVA). In NTVA, visual processing capacity is distributed across stimuli by dynamic remapping of receptive fields of cortical cells such that more processing resources (cells) are devoted to behaviorally important objects than to less important ones.

By use of the same basic equations used in TVA, NTVA accounts for a wide range of known attentional effects in human performance (reaction times and error rates) and a wide range of effects observed in firing rates of single cells in the primate visual system. NTVA provides a mathematical framework to unify the 2 fields of research–formulas bridging cognition and neurophysiology. (PsycINFO Database Record (c) 2005 APA, all rights reserved)
