Visual search and line orientation discrimination was studied in 67 brain-damaged and 15 control subjects, with the aim of demonstrating that hemi-inattention follows both left- and right-hemisphere damage even when confined to the frontal lobe. Both anterior and posterior lesions of either hemisphere caused inattention to the side contralateral to the lesion, this asymmetry being pronounced at the onset of search, especially in patients with anterior lesions. Hemi-inattention was associated with the overall inefficiency of line orientation discrimination and exploration as well as simple verbal performance in right-hemisphere-damaged patients, but tended to dissociate from these deficits in left hemisphere-damaged patients. Brain-damaged patients were inferior to the control subjects, and women inferior to men in the overall efficiency of exploration, but only women with right posterior lesions had a deficit in line orientation discrimination.
对67名脑损伤患者和15名对照受试者进行了视觉搜索和线条方向辨别研究，目的是证明即使局限于额叶，半侧忽视在左、右半球损伤后均会出现。任何一个半球的前部和后部病变都会导致对病变对侧的忽视，这种不对称在搜索开始时尤为明显，尤其是在前部病变的患者中。半侧忽视与右半球损伤患者的线条方向辨别和探索的整体效率低下以及简单言语表现有关，但在左半球损伤患者中，这种忽视往往与这些缺陷分离。脑损伤患者在探索的整体效率上低于对照受试者，女性低于男性，但只有右后部病变的女性在线条方向辨别上存在缺陷。
