Visual significance of pupillary response to an auditory task.
Subjects simultaneously performed visual and auditory detection tasks. Pupillary dilation accompanies increased cognitive load such as that caused by the auditory tasks. Errors in the visual task increased when the auditory task became more difficult. The increase was greater when the effects of pupillary dilation were blocked by an artificial pupil.
