Hemispheric differences associated with Physical Identity Matching and Semantic Classification of Japanese characters (Kanji) were examined using visual event-related potentials and behavioural measures. Event-related potentials to the Kanji during matching tasks revealed hemispheric differences in the later components. Right hemisphere responses were larger than those or the left. The interaction of Types of Matches by Hemispheres was not significant. This interaction however was significant with the behavioural measure. On Semantic Classification Matching reaction times for right-visual-field Kanji were faster than those of the left field while no visual field difference was found for Physical Identity Matching. The sensitivity of both measures as indicators of laterality is discussed from the point of view of levels of processing.
使用视觉事件相关电位和行为测量方法，研究了与日文字符（汉字）的物理身份匹配和语义分类相关的半球差异。匹配任务期间对汉字的事件相关电位显示，后期成分存在半球差异。右半球的反应大于左半球。半球与匹配类型之间的交互作用不显著。然而，这种交互作用在行为测量中是显著的。在语义分类匹配中，右视野汉字的反应时间比左视野快，而在物理身份匹配中未发现视野差异。从加工水平的角度讨论了这两种测量作为偏侧性指标的敏感性。
