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.
