Task-Evoked Pupillary Responses and Cognitive Processing.

Abstract

The current status of the concept of processing resource in cognitive psychology is first presented. Difficulties with a purely behavioral theory of processing resources are then raised. Next the use of a physiological measure, task-evoked changes in pupillary diameter, as a reflection of general processing load is then proposed and the relevant research is reviewed. The measure is shown to yield consistant results across a range of qualitatively different mental tasks. Finally, a hierarchical physiological theory of processing resources is proposed. (Author)
