Change in Field of regard-response time
time interval between target onset and response with field of regard setting
Time frame: Baseline, 4 weeks from baseline, 8 weeks from baseline
Change in Field of regard-success rate
percentage of correct responses (clicking the left or right mouse button in response to a blue or red target, respectively) with field of regard setting
Time frame: Baseline, 4 weeks from baseline, 8 weeks from baseline
Change in Field of regard-head movement
sum of all quantified head-rotations with field of regard setting
Time frame: Baseline, 4 weeks from baseline, 8 weeks from baseline
Field of view-response time
time interval between target onset and response with field of view setting
Time frame: Baseline, 4 weeks from baseline, 8 weeks from baseline
Field of view-success rate
percentage of correct responses (clicking the left or right mouse button in response to a blue or red target, respectively) with field of view setting
Time frame: Baseline, 4 weeks from baseline, 8 weeks from baseline
Line bisection test
Participants were asked to bisect the given lines by marking the centre of each line using their preferred or unaffected hand
Time frame: Baseline, 4 weeks from baseline, 8 weeks from baseline
Star cancellation test
The experimenter crossed out the two small, central stars of the sheet as an example, following which participants were asked to mark the remaining small stars.
