Grouping influences in unilateral visual neglect.
Effects of grouping on unilateral neglect were investigated in 8 neurological patients with right hemisphere damage. It is well documented that arranging items to form a group spanning the midline decreases the magnitude of neglect. In the present study we examined how clusters of groups within the left or right visual field affect neglect and whether isolated groups within the neglected field ...
متن کاملUnilateral visual neglect overcome by cues implicit in stimulus arrays.
The case of a man with a right hemisphere lesion and with evidence of left-sided visuospatial neglect is reported. On a variety of verbal and nonverbal tasks his performance was significantly modified by information implicit in stimulus configurations. Neglect deficits were present on tests involving spatially distinct or meaningless stimulus arrays but almost absent when stimuli were continuou...
متن کاملThe imbalance of oculomotor capture in unilateral visual neglect.
Visual neglect has been associated with an imbalance in the level of activity in the saccadic system: activity in the contralesional field is suppressed, which makes target selection unlikely. We recorded eye movements of a patient with hemispatial neglect and a group of healthy participants during an oculomotor distractor paradigm. Results showed that the interfering effects of a distractor we...
متن کاملThe contribution of spatial remapping impairments to unilateral visual neglect.
Left visual neglect following right hemisphere damage is a heterogeneous phenomenon, in which several underlying impairments have been identified. Despite recent advances in understanding the neural and cognitive bases of these impairments, current theories of neglect, particularly those that emphasise attentional deficits, do not explain a number of phenomena, including: 'Ipsilesional' neglect...
متن کاملAssessment of unilateral neglect.
U nilateral neglect (ULN) (or “neglect”) is a common behavioral syndrome in patients following stroke. The reported incidence of ULN varies widely from 10%1 to 82%2 following right-hemisphere stroke and from 15%3 to 65%2 following left-hemisphere stroke. Reasons for the variability in the published rates of occurrence of ULN after stroke include subject selection criteria, lesion site, and the ...
