Abstract

Cerebral lateralization of global-local processing of 70 left-handed and 70 right-handed students was compared using a computerized global-local task in a half-visual field paradigm. Analysis showed that left-handed individuals were slower than right-handed individuals in processing Globally Directed stimuli presented to the left visual field (right hemisphere). In addition, left-handed individuals showed smaller local superiority in the left hemisphere to the right-handed individuals. These findings are more consistent with Levy's prediction of spatial inferiority of left-handed individuals than Geschwind and Galaburda's or Annett's hypotheses.

摘要

使用半视野范式下的计算机化全局-局部任务，比较了70名左利手学生和70名右利手学生在全局-局部加工中的大脑半球偏侧化情况。分析表明，在处理呈现给左视野（右半球）的全局导向刺激时，左利手个体比右利手个体速度更慢。此外，与右利手个体相比，左利手个体在左半球表现出较小的局部优势效应。这些发现与利维关于左利手个体空间劣势的预测比与 Geschwind 和加拉布尔达的假设或安妮特的假设更为一致。
