The pupil has long been seen as a unique window into the mind, and researchers are increasingly interested in analysing pupil size data recorded by video-based eye trackers in order to gain insights into cognitive and emotional processes during task performance. This advanced workshop will outline the theoretical rationale for pupillometry, and the key methodological issues that need to be considered by EyeLink users when recording and analysing pupil data.
Pupillometry can potentially reveal important insights concerning cognitive processes and emotional responses during task performance. However, in order to generate meaningful pupillometry data from video-based eye trackers, there are a number of important methodological issues that need to be understood. These include the pupil foreshortening effect, the importance of baseline pupil size measurements, and controlling for a range of non-cognitive influences on pupil size, such as luminance changes. In this advanced workshop, you will learn how to carry out effective pupillometry research using SR Research EyeLink eye trackers.
The course will focus on providing hands on, practical advice, and will cover the recording, analysing and reporting of pupillometry data, using worked examples and example data sets. Two EyeLink 1000 Plus systems will be available.
Please note that you will need to bring a laptop that has the latest version of Experiment Builder and Data Viewer installed. Temporary USB license keys will be provided for people who are not able to bring their own.
Why Study this Course?
- Understand the potential (and limitations) of pupillometry as a research tool.
- Discover the range of methodological issues that need to be taken into consideration in pupillometry research.
- Learn how to convert EyeLink pupil data to mm.
- Learn how to use Experiment Builder to create a basic pupillometry task.
- Gain hands on experience in using Data Viewer to analyse and interpret pupillometry data, using trial, sample and time series (binning) reports.

Dr Sam Hutton
Dr Sam Hutton has extensive experience of using EyeLink systems, both for his own research (with over 50 published papers) and more recently, in his role as consultant for SR Research. His eye tracking research interests include basic oculomotor function in people with neurological and psychiatric disorders , the relationship between attention / memory and eye movements, pupilometry and eye movements during reading. He has trained hundreds of researchers, and conducted workshops across the world. He has a detailed understanding of all aspects of eye tracking research, and a wealth of practical experience to share.
Dr Gustav Kuhn
Dr Gustav Kuhn is a Reader in the Psychology Department at Goldsmiths, University of London and director of the MAGIC lab (Mind Attention and General Illusory Cognition). He has extensive experience in eye tracking research, and much of his research has focused on measuring eye movements during naturalistic interactions and exploring how magicians misdirect people’s attention.

- Discovered how to produce and interpret a range of Data Viewer reports containing pupil data.
About the department
Our Department of Psychology runs a range of exciting undergraduate and postgraduate programmes, as well as being a thriving centre of excellence in research. There are four main research centres within the department, including:
The Centre for Cognition and Neuroscience – which investigates cognition and its underlying neurobiological mechanisms.
The Centre for Development and Educational Science – which conducts scientific research into the development of cognitive, perceptual, social and emotional processes from infancy into childhood and adolescence.
The Centre for Forensic and Clinical Science – a dynamic hub for research, specialist teaching and consultancy within the area of forensic and clinical psychology.
The Centre for the Science of the Creative and Performing Arts – which investigates the cognitive and neural bases of music, dance and visual arts.
This course has been developed in collaboration with SR Research. Since its inception 25 years ago, SR Research has been exclusively dedicated to supporting and responding to the needs of the eye-movement research community. There are a number of Eye Tracking courses available including:
