Abstract

Changes in pupil size offer a rich, continuous, and integrated neurophysiological readout of attention and cognition. I here briefly reintroduce examples of a vast, forgotten literature, full of inspiring ideas, which described attentional modulations of pupil size decades earlier than often assumed. I outline parallels between these early studies and recent developments in pupillometry.
