Primary Outcome Measures

Name	Time	Method
<p>Task 1: The main parameter in task 1 is the Just Noticeable Difference (JND)<br /><br>for visual temporal order. The JND reflects the smallest time difference (in<br /><br>milliseconds) between the two visual stimuli (flashes) that participants need<br /><br>to perceive for a correct visual temporal order. The JND is calculated for each<br /><br>group and the two conditions of the task.</p><br>

Secondary Outcome Measures

Name	Time	Method
<p>Task 2: the percentage omissions (total number of omissions divided by total<br /><br>number of targets) reflects a subject's degree of neglect.</p><br>
