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.
SR Research manufactures the EyeLink range of eye trackers – devices that have been the driving force behind the most innovative eye-tracking research of the last two decades. Renowned for their exceptional levels of accuracy and precision, combined with high sampling speeds, their eye trackers are used in top laboratories worldwide.
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.
