What this trial measures

  • Behavioral response (button press)Through study completion, an average of two weeks

    Participants will be required to report the orientation of a line (horizontal or vertical) within the target via a speeded button press. The specific values of color, shape, and motion will vary randomly from trial to trial. Participants will complete separate sessions with each session directing participants to search for a different target feature dimension.

  • Gaze positionThrough study completion, an average of two weeks

    The investigators will use the measured gaze position in (x,y) coordinates to verify stable fixation throughout the experiment. The data will be used to establish gaze fixation and/or track where participants look as they perform the visual search task. Trials with poor fixation performance may be excluded from further analyses.
