Pupil Diameter Versus Task Layout.

Abstract

Using pupil size as an indirect measure of mental activity, this experiment investigated a spatially compatible and non-compatible forced choice task. It was found subjects could process a higher presentation rate in the compatible layout than in the non-compatible layout without going into an overload condition. Also, when subjects were already in a pupil constricted condition (overloaded) in a non-compatible arrangement, it was found the constriction could be significantly reduced by switching to a compatible arrangement.
