[en] Patients suffering from left unilateral neglect fail to perceive or respond to stimuli presented within the contralesional space. Neglect is generally considered as involving an attentional bias towards the ipsilateral side. Recently, it has been suggested that revisiting and perseveration behaviors in visual search tasks shown in parietal neglect could be related to impairment in visuo-spatial working memory (Husain et al., 2001; Wojciulik et al., 2001). The aim of the present study was to investigate which aspect of visuo-spatial working memory is involved in unilateral neglect. Indeed, different source of evidence support the idea that visuo-spatial working memory involves at least two separate cognitive subsystems: the visual cache and the inner scribe (Logie, 1995; Pickering et al., 2001). We assessed thirteen right-damaged patients suffering from left neglect on two experimental task involving either spatial (Corsi test) or visual (Span test) working memory. Results show that visual and/or spatial working memory can be impaired in spatial neglect. This double dissociation provides neuropsychological support for the separation of visuo-spatial working memory into two subcomponents. The clinical and anatomical implications of this finding are discussed.
