The Pupil as Marker of Cognitive Processes

  • Wolfgang EinhäuserEmail author
Part of the Cognitive Science and Technology book series (CSAT)


Of all peripheral measures of (neuro-)physiological activity, pupil size is probably the easiest to access. Far beyond its well-known reaction to light incident on the eye, pupil size is a rich marker of many cognitive processes. Since the turn of the millennium, the increasing availability of video-based eyetracking devices has led to a renaissance of pupillometry as research technique in the cognitive neurosciences. The chapter reviews recent developments in this field. How do emotional and cognitive factors, attention and memory, influence pupil size? What is the role of the pupil in social interactions and which applications of pupillometry are currently envisioned? How can pupillometry be combined with other techniques? And what are the limits, pitfalls and caveats when using the pupil as marker of cognitive processes?
