HCL | Example dataset from that contains binocular eye data from two participants from a simple contingency learning task (the data are from Beesley, Nguyen, Pearson, & Le Pelley, 2015). In this task there are two stimuli that appear simultaneously on each trial (to the left and right of the screen). Participants look at these cues and then make a decision by selecting an "outcome response" button. Data was recorded with a Tobii TX300 sampling at 300Hz. Participant sat approximately 60 cm from the screen. The screen resolution was 1920 x 1080.
