A circle-monitor for computerised assessment of visual neglect in peripersonal space.

<h4>Unlabelled</h4>Current assessment of visual neglect involves paper-and-pencil tests or computer-based tasks. Both have been criticised because of their lack of ecological validity as target stimuli can only be presented in a restricted visual range. This study examined the user-frien...
