60名正常的右撇子（30名从左到右和30名从右到左的阅读者）和两名左侧单侧忽视患者，他们具有相反的阅读习惯，进行了被动的线平分任务。为了研究扫描方向对操作的影响，受试者必须停止从左到右或相反方向移动的标记。结果表明，对于所有被试来说，主观中间的位置取决于线的扫描方向。从左到右扫描时，出现了一个小的偏移，而当标记从右向左移动时，出现了一个小的偏移。这些结果强调了扫描方向在空间组织中的作用，并就单侧忽视的解释性假设进行了讨论。(C)1998 Elsevier Science B.V.保留所有权利。
Sixty normal dextrals (30 left-to-right and 30 right-to-left readers) and two left unilateral neglect patient with opposite reading habits performed a passive line bisection task. In order to study the effect of scanning direction on performance, subjects had to stop a mark moving on the to-be-bisected line either from the left to the right or in the opposite direction. Results showed that the position of the subjective middle was dependent upon the scanning direction of the line for all the subjects. A leftward deviation appeared for left to right scanning, whereas a rightward shift occurred when the mark moved from the right to the left. These results emphasize the role of scanning direction in space organization and are discussed with respect to the explanatory hypotheses of unilateral neglect. (C) 1998 Elsevier Science B.V.
