Abstract

The recently proposed association between semantic paralexias and right hemispheric reading processes was investigated in normals with a tachistoscopic half-field reading experiment. With extremely brief lateralized exposure of nouns, permitting only 25% of correct reading, semantic paralexias were induced. These semantic substitutions occurred three times more often to LVF (right hemisphere) than to RVF (left hemisphere) presentations, whereas other errors were observed with similar frequency to both visual fields. We concluded that semantic paralexias, as they are observed in patients, occur in normals induced by reduced reading time and are the product of right hemispheric reading processes.

摘要

通过速示半视野阅读实验，对正常人群进行研究，以探讨近期提出的语义性错读与右半球阅读过程之间的关联。在对名词进行极短暂的单侧呈现时，仅允许25%的正确阅读，从而诱发了语义性错读。这些语义替代现象在左视野（右半球）呈现时出现的频率比在右视野（左半球）呈现时高两倍，而其他错误在两个视野中出现的频率相似。我们得出结论，正如在患者中观察到的那样，语义性错读在正常人群中可由缩短的阅读时间诱发，并且是右半球阅读过程的产物。
