Primary Outcome Measures

Name	Time	Method
<p>Main study parameters are related to (timing of) gaze behaviour during several<br /><br>reaching and object manipulation tasks such as proportions of task duration<br /><br>with gaze focused on task-relevant objects (TRO gaze), on task-relevant body<br /><br>parts (TRB gaze), and on task-irrelevant objects (TIO gaze) (expressed in<br /><br>percentages of total task duration).</p><br>

Secondary Outcome Measures

Name	Time	Method
<p>To explore whether, and how, visuomotor behaviour of stroke survivors differs<br /><br>from healthy controls<br /><br>To explore whether, and how, visuomotor behaviour of stroke survivors differs<br /><br>between participants with left- and right hemisphere strokes</p><br>
