A patient with surgical section of the splenium and, probably, the posterior end of the truncus of the corpus callosum was studied 9-13 yr after the operation. His reading aloud, reading comprehension and word-matching abilities were moderately disturbed only in the left hemifield. These three disturbances were equally disturbed. The disturbances were not the result of visual disturbances such as tachistoscopic hemiamblyopia or tachistoscopic hemineglect since Landolt's ring matching was intact in the left hemifield as well as in the right. The disturbances were also not due to the disturbance of tachistoscopic word perception since the patient correctly performed same-different judgment of pairs of words in each hemifield. In his reading aloud and reading comprehension disturbances, ideogram words were less impaired than phonogram words, even when the number of letters in the words was the same. His picture naming ability was not disturbed in each hemifield.
对一名胼胝体压部以及可能还有胼胝体干后端接受手术切断的患者在术后9至13年进行了研究。他的大声朗读、阅读理解和单词匹配能力仅在左半视野受到中度干扰。这三种干扰程度相当。这些干扰并非由诸如速示半侧弱视或速示半侧忽视等视觉干扰导致，因为兰多尔特环匹配在左半视野和右半视野均完好无损。这些干扰也不是由于速示单词感知障碍所致，因为该患者在每个半视野中对单词对的异同判断都是正确的。在他的大声朗读和阅读理解干扰中，表意文字受到的损害比表音文字小，即使单词中的字母数量相同。他的图片命名能力在每个半视野中均未受到干扰。
