Pupillometric Measurement of Cognitive Workload in Processing Numerical Visual Displays

Abstract

The momentary workload that is imposed by a cognitive task upon the limited capacity human information-processing system appears to be accurately reflected in the momentary level of central nervous system activation. The utility of pupillometric methods of workload assessment is tested in an experiment involving the perception of four-digit visual displays of varying degrees of clarity. Pupillary dilations accurately reflect the cognitive load imposed by these displays, even in the absence of encoding errors.
