The relationships between hemispheric function and components of the imagery process were examined in patients with unilateral right and left brain damage and in intact adult subjects. In the image generation condition, subjects were required to mentally generate Katakana letters corresponding to Hiragana letters displayed on a CRT. The results for the intact adults suggested a left hemisphere superiority, but the unilaterally brain-damaged subjects showed no hemispheric difference in this task. In the imagery operation task (transformation or lateral translation), subjects were asked to find a genuine Kanji among distractors (pseudo-Kanji) that were constructed from two Kanji radicals (themselves real Kanji) that were either displayed in reverse order or shifted apart. The results for both intact adults and patients with unilateral brain damage suggest the superiority of the right hemisphere.
研究了右脑和左脑单侧损伤患者以及正常成年受试者半球功能与意象过程各组成部分之间的关系。在图像生成条件下，要求受试者在脑海中生成与阴极射线管（CRT）上显示的平假名相对应的片假名。正常成年人的结果表明左半球优势，但单侧脑损伤受试者在该任务中未表现出半球差异。在意象操作任务（变换或横向平移）中，要求受试者在由两个汉字部首（本身为真正的汉字）以相反顺序显示或分开排列构成的干扰项（假汉字）中找出一个真正的汉字。正常成年人和单侧脑损伤患者的结果均表明右半球优势。
