Eye Tracking: Neuropsychiatric Research
From decreased volitional saccade amplitude in Parkinson’s disease, to abnormal scan paths when looking at faces in patients with schizophrenia, researchers have used eye tracking technology to better understand the neurophysiological and neurocognitive bases of a wide range of neurological, psychiatric and psychological disorders. In this advanced EyeLink Workshop, participants will discover the wide range of eye tracking techniques that have been used to explore oculomotor dysfunction in neuropsychiatric research.
The course will focus on providing hands on, practical advice on maximising eye tracker data quality, using Experiment Builder to create a range of tasks assessing basic oculomotor function (pro, anti, predictive and remembered saccade tasks, fixation stability, smooth pursuit), and using Data Viewer to process and interpret the data from such tasks. It is important that participants bring a laptop that has the latest versions of Experiment Builder / Data Viewer installed. Temporary Experiment Builder / Data Viewer software license keys will be provided for people who are not able to bring their own. For the last session, attendees will need Fieldtrip (and matlab) installed if they want to follow along.

Schedule
09:00 - 09:30: Registration / Welcome
09:30 - 10:30: Participant set up and Calibration for neuropsychiatric research. This practical session will cover setting up and calibrating participants using the EyeLink 1000 Plus. The session will include advice on how to maximise and measure data quality, and how to approach calibration for a range of patients.
10:30 - 11:00: Tea / Coffee Break
11:00 - 12:30: Background– A primer on the basics of oculomotor control – the neural mechanisms underlying saccades, fixation and smooth pursuit, and a quick over view of research into oculomotor abnormalities in neuropsychiatric populations.
12:30 - 13:30: Lunch
13:30 - 15:00: Implementing a range of saccade tasks in Experiment Builder, and analysing the resulting data using Data Viewer and Excel
15:00 – 15:30: Tea / Coffee Break
15:30 - 17:00: Implementing smooth pursuit tasks using Experiment Builder and analysing pursuit and Data Viewer and Excel
