Eyetracking

 

We use eyetracking to investigate how the brain allocates attention and processes information during scene perception, reading, and visual search. We primarily use SR Research Eyelink 1000 and 1000+ eyetrackers set up for a variety of paradigms, including real-time saccade-contingent display changes to generate artificial scotomas (blind spots) and moving windows (tunnel vision).


Co-registered eyetracking and neuroimaging: We combine high-resolution eyetrackers with EEG/ERP systems at the Center for Mind and Brain and with a Siemens Trio 3T MRI scanner at the Imaging Research Center. This allows us to simultaneous collect and co-register eye movement and neuroimaging data.
