Visual hemispatial neglect, re-assessed.
Increased computer use in clinical settings offers an opportunity to develop new neuropsychological tests that exploit the control computers have over stimulus dimensions and timing. However, before adopting new tools, empirical validation is necessary. In the current study, our aims were twofold: to describe a computerized adaptive procedure with broad potential for neuropsychological investig...
متن کاملVisual information processing in hemispatial neglect.
Hemispatial neglect is a complex neuropsychological disorder characterized by a severe attentional deficit that produces a lack of awareness for information appearing in contralesional hemispace. Despite this lack of phenomenal awareness, recent studies suggest that a great deal of visual information processing does occur and can influence the performance of patients in certain tasks. The curre...
متن کاملHemispatial neglect.
The syndrome of hemispatial neglect is characterised by reduced awareness of stimuli on one side of space, even though there may be no sensory loss. Although it is extremely common, it has proven to be a challenging condition to understand, and to treat. New insights from detailed behavioural and anatomical studies in patients, as well as functional imaging in healthy individuals, have begun to...
متن کاملPreattentive and attentive visual search in individuals with hemispatial neglect.
Preattentive and attentive visual processing was examined in patients with hemispatial neglect, hemispatial neglect with hemianopia, and control participants. In the preattentive search task, targets possessed a unique feature that was not shared by distractors. In the attentive search task, targets lacked a feature that was present in the distractors. Preattentive search was normal in 3 neglec...
متن کاملPrism adaptation improves visual search in hemispatial neglect.
Visuomotor prism adaptation has been found to induce a lateral bias of spatial attention in chronic hemispatial neglect patients. Here, two experiments were conducted to explore the effects of 10 degrees prism adaptation on visual search tasks and standard visual inattention tests. Baselines and intervention effects were measured on separate days for all patients. The first experiment explored ...
