Researchers are increasingly aware of the advantages of combining eye tracking with EEG and other neurophysiological recording techniques such as fNIRS. In this advanced workshop, you will learn how to set up SR Research EyeLink systems to interface with a range of EEG/fNIRS systems, using both TTL signalling and more advanced integration (for EGI systems). The workshop will also cover how to co-register eye tracking and EEG data using Fieldtrip software.
Combining eye tracking and EEG can have several advantages. For certain EEG scenarios, eye movements (not just blinks) can introduce large artefacts into recordings, causing issues for subsequent analysis. In these scenarios, it is important to have reliable eye tracking data in order to be able to discard relevant trials/portions of data. Eye tracking can also be used to limit what is shown to participants and when it is shown, for example only presenting targets when participants are fixating centrally, or making peripheral targets disappear if gaze leaves the central target. Eye Tracking can also provide useful secondary information concerning cognitive workload and engagement.
More recently, researchers have begun to explore concepts such as 'fixation related potentials' in tasks including reading and visual search. In this workshop, we will discuss the range of scenarios in which combining eye tracking with EEG can be advantageous, and outline strategies for synchronisation and data co-registration.
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. For the last session, you will also need Fieldtrip (a matlab toolbox) installed in order to follow along.

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.

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:
