We report three studies of visual search in a patient with left neglect after a right parietal infarct. Manipulations whereby the patient's attention is explicitly drawn to the spatial extent of the page on which the stimuli for cancellation are displayed have little or no effect on the number of targets cancelled. The results are consistent with a "zoom lens" model of attentional deployment. "Neglect" on search tasks seems to reflect a systematic bias that emerges when global attention is constricted to permit analysis of local features.
我们报告了三项针对一名右侧顶叶梗死致左侧忽视患者视觉搜索的研究。通过操纵使患者的注意力明确指向显示用于划消刺激的页面空间范围，对划消的目标数量几乎没有影响。这些结果与注意力分配的“变焦透镜”模型一致。搜索任务中的“忽视”似乎反映了一种系统性偏差，当全局注意力受限以允许对局部特征进行分析时就会出现这种偏差。
