- Primary Outcome Measures
Name Time Method <p>Visual search of the participants<br /><br>-Search rate; the mean number of useful visual fixations and the mean fixation<br /><br>duration per trial. A fixation is defined as the period of time when the point<br /><br>of gaze remains stationary within 1.5 degrees of movement tolerance for a<br /><br>period equal to, or greater than 120ms or 6 video frames (Williams et al.,<br /><br>1994). We expect the following useful visual fixation points; ball,<br /><br>interception area (see lab setup).<br /><br>-Percentage viewing time; the amount of time participants spends on fixating to<br /><br>the various areas (ball, begin point, interception point) </p><br>
