A Model for Visual Attention.

Abstract

A model for shifts of human visual attention was developed and tested. The model predicts confusion in the preceived order of visually-presented items (RSVP paradigm) following a shift of visual attention to the location in which those items are presented. The model was confirmed over a range of presentation rates, and two types of visual characters (numerals and outline shapes). The function describing the attention shift does not vary as the spatial distance over which attention may be moved is varied, nor does it vary if the eyes shift or remain fixed when attention moves, so that the effect of attention seems rather to open a gate into short-term visual memory (independent of visual space), than to 'move' attention across visual space. This is compatible with the current model.
