چکیده انگلیسی
Visuospatial attentional asymmetry has been investigated by the line bisection task in patients with schizophrenia, however, those studies are in small number and the results are controversial. The present study aimed to investigate hemispatial neglect in patients with schizophrenia (n=30), their healthy siblings (n=30) and healthy individuals (n=24) by a computerized version of the line bisection task. Deviation from the midline for both hemispaces (mean bisection error-MBE) were calculated and the effects of both hand and line length were controlled. Repeated measures ANOVA yielded a significant hemispace effect for the MBE scores, but no group or groupÃhemispace interaction effect, i.e., all three groups were inclined to a leftward bias in the left and a rightward bias in the right hemispace. MBEs were significantly different from “zero” only for the right hemispace in siblings and for the left hemispace in controls. Negative symptoms were significantly correlated with the bisection errors in the right hemispace. The results of the present study do not support aberrant hemispheric asymmetry, but bigger bisection errors in schizophrenia.
