Evidence supporting individual variations in patterns of hemispheric involvement in the recognition of visuo-spatial and verbal stimuli among dextrals is reported. In Experiment 1, subjects' asymmetry scores on a task that was nonlateralized for the group as a whole were significantly correlated with their asymmetry scores on right-hemisphere-specialized tasks, including face recognition. In Experiment 2, subjects' asymmetry scores on a task that was nonlateralized for the group as a whole were significantly correlated with their asymmetry scores on a left-hemisphere-specialized word recognition task. These results suggest that individual dextrals' asymmetry scores on lateralized tasks are a joint function of a subject's underlying hemispheric specialization for that task and stable individual variations in asymmetric hemispheric reliance.
有证据表明，在右利手人群中，大脑半球参与视觉空间和言语刺激识别的模式存在个体差异。在实验1中，对于整个群体而言非单侧化任务的受试者不对称分数，与包括人脸识别在内的右半球专门任务的不对称分数显著相关。在实验2中，对于整个群体而言非单侧化任务的受试者不对称分数，与左半球专门单词识别任务的不对称分数显著相关。这些结果表明，个体右利手在单侧化任务上的不对称分数，是受试者对该任务潜在半球专门化以及不对称半球依赖中稳定个体差异的共同作用。
