ADHD Pupil Size Dataset

Data are organized in a Matlab® structure array called Pupil_dataset, which contains one index per session recorded. The structure contains five fields:<br> <i>Subject</i>. An integer identifying a given participant.<br>Age. Participant age (in years), at the moment of performing the task.<br><i>Group</i>. Experimental group: ‘off-ADHD’, ‘on-ADHD’ and ‘Ctrl’, indicating off-medication ADHD participant, on-medication ADHD participant, and control participant, respectively.<br><i>Task_data</i>. Table array containing all the raw data from that participant and session. The data are arranged in four columns: ‘Time’, provides the timestamps in milliseconds. ‘Diameter’, contains the pupil diameter, in arbitrary units. ‘Position’, contains the x- and y-coordinates of the gaze positions, in pixels, relative to the screen size in pixels (1920 x 1080). ‘Events’, contains the relevant task and behavioral events.<br> <i>Task_epoch.</i> Table array containing processed pupil data, with one epoch per trial. Rows are trials and columns are events and data. ‘Trial’ column simply indexes the trial. ‘Load’ codes the memoranda types, indicating one-dot (1) or two-dot (2). ‘Distractor’ codes the distractor types. ‘CorrResponse’ contains the information about the correct response the participant was expected to give. ‘Perform’ corresponds to the participant’s performance, which could be either correct (1) or incorrect (0). ‘RTime’ contains the reaction time in milliseconds. ‘Pupil’ contains two vectors, containing the session timestamps and the the pupil in z-score units. The data in Task_epoch corresponds to the data used in Wainstein et al (2017). <br> <i>WISC</i>. This field consists of a table array with the WISC data. Each column corresponds to a subtest within WISC and the entries contain the associated scores.<br>
