The first purpose of the present research was to investigate the mechanism of interhemispheric integration. The previous model suggested that the benefits of bihemispheric processing was enhanced as the processing load of the task was higher. The present results demonstrated that the benefits of bihemispheric processing was reduced in the condition where the processing load between the hemispheres in the across-hemisphere condition was imbalanced even when the task complexity was relatively higher. These results suggested that the imbalance of the processing load between the hemispheres would hamper each hemisphere to work in parallel.The second purpose of the present research was to examine the effects of visual familiarity of words on interhemispheric lexical processing. Word or pseudoword was briefly presented in a left, right or bilateral visual-field. Previous findings suggested that a bilateral gain, in which the performance in a bilateral visual-fields condition was superior to … More that in a unilateral visual-field condition, showed up in the word condition, not in the pseudoword condition. The present results demonstrated that such a word-specific bilateral gain was obtained only in the visually familiar condition, not in the visually unfamiliar condition. These results suggested that the visual familiarity for a word had an influence on the interhemispheric lexical processing.The third purpose of the present research was to investigate the interhemispheric interaction using a flanker paradigm. A pair of Kanji color-word and colored simple figure (distracter) was briefly presented in a unilateral visual-field or divided bilateral visual-fields. The subjects were asked to identify the ink color of Kanji color-word. The results showed that when the ink color of color-word was incompatible with that of a distracter, the Stroop-like interference was obtained. Furthermore, the degree of the interference was attenuated in the bilateral visual-field condition, compared with the unilateral visual-field condition. Less

本研究的第一个目的是探讨大脑半球间整合的机制。先前的模型表明，随着任务的加工负荷的增加，双半球加工的益处得到增强。本研究结果表明，在跨半球条件下，即使任务的复杂性相对较高，当两半球之间的加工负荷不平衡时，双半球加工的益处也会降低。这些结果表明，两半球之间的加工负荷不平衡会阻碍两半球的平行工作。本研究的第二个目的是探讨词汇的视觉熟悉性对两半球间词汇加工的影响。词或假词在左、右或双侧视野中短暂呈现。以前的研究结果表明，双侧增益，其中在双侧视野条件下的性能优于上级 ...更多信息 在单侧视野条件下，出现在单词条件下，而不是伪单词条件下。目前的研究结果表明，这样的词特异性双边增益只在视觉熟悉的条件下，而不是在视觉不熟悉的条件下获得。本研究的第三个目的是采用侧面范式探讨两半球间的相互作用。一对汉字色词和彩色简单图形（干扰项）在单侧视野或双侧视野中短暂呈现。被试被要求识别汉字颜色词的墨水颜色。结果表明，当色词的墨水颜色与干扰项的墨水颜色不一致时，会产生类Stroop干扰。此外，与单侧视野条件相比，双侧视野条件下的干扰程度有所减弱。少
