The interaction of rate of presentation, and number of transforms and possible responses was examined in connexion with the effect of cognitive load upon pupillary dilation. The task involved continuous processing of auditorily presented material. The two criteria of task difficulty both contributed to raising pupillary diameters, which were further increased at the moment of button‐press responding. That variations in level arousal were involved was further borne out by the tendency for certain regular changes to occur in pupillary dilation in the course of the processing tasks.
