I. Basics

With the increased application of eye tracking in infant research the measure of pupillometry has become more and more popular. What can pupil size tell us? How is it measured? What are potential problems when designing and running a pupillometry study? These issues are covered in part I

II. Oscillations

Auditory stimuli that occur regularly in time are known to cause neural and motor entrainment – i.e. the synchronization of neural and motor activity to the temporal regularities in the auditory signal. The second part of the workshop will show that also human pupils entrain to rhythmic stimuli. It will demonstrate how to measure pupillary entrainment and how it can be used to investigate rhythm perception in adults and infants.
