Neglect patients often present with a rightward shift of the direction straight-ahead of body midline. We investigated whether directions ahead of other body parts were similarly shifted or were differentially affected. Right brain-damaged patients, with and without neglect, and normal subjects had to indicate by manual pointings, the directions straight-ahead of the navel, the nose, the left and right shoulders. In neglect patients, constant errors varied across directions with a decrease in magnitude from left to right, suggesting a compression of body projection in extracorporeal space. Moreover, the projection of the left hemibody was smaller than the right in all subjects, with and without neglect. This unexpected finding is discussed with regard to other spatial asymmetries observed in normal subjects.
忽视症患者常常表现出身体中线正前方方向的右移。我们研究了身体其他部位前方的方向是否也有类似的偏移，或者是否受到不同的影响。有忽视症和无忽视症的右脑损伤患者以及正常受试者必须通过手动指示来表明肚脐、鼻子、左右肩膀正前方的方向。在忽视症患者中，恒定误差随方向而变化，从左到右幅度减小，这表明体外空间中身体投射存在压缩。此外，无论有无忽视症，所有受试者左半侧身体的投射都比右半侧小。针对在正常受试者中观察到的其他空间不对称性，对这一意外发现进行了讨论。
