Right unilateral spatial neglect (USN) was investigated on three left brain-damaged patients suffering from the right homonymous hemianopsia and hemiplegia. A test battery consisted of visuo-constructive praxis; 1) putting blocks into a box, 2) bisecting a horizontal line, 3) figure drawing, 4) drawing of a dial plate and 5) copying drawing. The investigation revealed that USN of left brain-damaged patients resulted from 1) generally impaired mental function, 2) right unilateral sensory deprivation and 3) right hemiplegia. It was guessed that, as for a patient with right homonymous hemianopsia and hemiplegia, his attention would be attracted toward the left hand, and then he would be apt to neglect the right side. Right USN was not so prominent compared with the left one of right hemispheric lesion. However, it is suggested that if clinicians examine carefully the visuo-constructive function in addition to aphasia on left brain-damaged patients, right USN appears greater in some cases.
对三名患有右侧同向性偏盲和偏瘫的左脑损伤患者进行了右侧单侧空间忽视（USN）的研究。一套测试包括视觉构建实践：1）将积木放入盒子中；2）平分一条水平线；3）图形绘制；4）表盘绘制；5）临摹绘图。调查显示，左脑损伤患者的USN是由以下原因导致的：1）一般精神功能受损；2）右侧单侧感觉剥夺；3）右侧偏瘫。据推测，对于患有右侧同向性偏盲和偏瘫的患者，其注意力会被吸引到左手，然后容易忽视右侧。与右侧半球病变患者的左侧USN相比，右侧USN并不那么突出。然而，建议临床医生在检查左脑损伤患者时，除了失语症外，仔细检查视觉构建功能，在某些情况下，右侧USN会更明显。
