Webinar

Measuring pupil size with eye tracking

Best practices for data collection, preprocessing and analysis

Webinar information

Fluctuations in pupil size provide insights into diverse cognitive processes, such as interest, cognitive load, attention, and surprise. Guest speakers, Prof. Dr. Mariska Kret and Prof. Dr. Sylvain Sirois, experts in measuring pupil size with eye tracking, will provide a methodological walk-through of best practices for data collection and analysis. Their presentations will include practical examples from research with non-human primates, human adults, and infants.

Watch the webinar to learn:

  • Pupil size data collection, preprocessing and analysis using eye tracking

  • The PhysioData Toolbox demo for pupil size recordings

  • Correlating pupil responses to behavior and cognitive processes in humans and non-human primates

Speakers

  • Prof. Mariska Kret

    Prof. Dr. Mariska Kret

    Professor Cognitive Psychology, Leiden University

    Mariska Kret is a full professor of comparative psychology and affective neuroscience at Leiden University in the Netherlands. Prior to this appointment she was a guest staff member at Caltech and assistant professor at the University of Amsterdam. She holds a PhD in neuropsychology from Tilburg University and completed a postdoc at Kyoto University. Her research focuses on emotions, comparative cognition, and social neuroscience.

  • Tobii Anouschka Van Dijk

    Anouschka van Dijk

    PhD. candidate, Leiden University

    Anouschka van Dijk is a PhD student supervised by Prof. Kret. In her research she combines eye tracking and psychological methods in order to better understand emotion processing difficulties in people with autism and social anxiety disorder. She enjoys involving children in academia and has performed in several theatre shows to spike academic interest in the new generation.

  • Prof. Sylvain Sirois

    Prof. Dr. Sylvain Sirois

    Professor, Psychology Department, University of Quebec, Trois-Rivières

    Sylvain is a professor of psychology at Université du Québec. From a background in neural network models of learning and development, he ended up studying habituation and, eventually, actual infants. Eye tracking had become the gold standard in the field but, strangely, pupil dilation remained a distant memory of the late 1960s (unlike in other areas of psychology). With an eye tracker and some useful statistical tools, he became an advocate for a renewed interest in pupillometry in infant research.

  • Tobii Pro employee Dr. Marisa Bondi

    Dr. Marisa Biondi

    Senior Research Scientist and Funding and Support Manager, Tobii

    Dr. Biondi has a Ph.D. in Psychological & Brain Sciences from Texas A&M University and used fNIRS and eye tracking to study the functional organization of the developing human brain.
