In two experiments a name and a face (each male or female) were simultaneously flashed to either the same or opposite visual fields (left or right), for matching congruent (same sex) or incongruent (opposite sex), to test the predictions of various models of hemispheric specialization. While overall best performance occurred with a face in the left visual field (LVF) and a name in the right visual field (RVF), and worst with the opposite configuration, the general pattern of results was incompatible with either a direct access model or an activational/attentional account. The results were, however, most compatible with the predictions of a semispecialized hemispheres account, whereby cerebral asymmetries are seen as relative rather than absolute, either hemisphere being capable of processing either kind of material (verbal or visuospatial), but to different levels of efficiency. However, despite the fact that the stimulus materials had previously been shown to produce stable and consistent lateral asymmetries in the predicted directions when presented in isolation, in the composite, integrative matching task the position of the name seemed to be the major determinant of the resultant asymmetries. It would seem therefore that when such stimuli are to be cross matched, either left hemisphere (language) processes somehow dominate right hemisphere (visuospatial) processing (though not in the way that would be predicted by a simple activational/attentional account) or the left hemisphere's greater capacity predominates.
在两项实验中，一个名字和一张面孔（均为男性或女性）同时闪现到相同或相对的视野（左或右），以匹配一致（同性）或不一致（异性），从而测试各种半球特化模型的预测。虽然总体上最佳表现出现在面孔在左视野（LVF）而名字在右视野（RVF）时，而相反配置时表现最差，但结果的总体模式与直接访问模型或激活/注意理论均不相符。然而，结果与半特化半球理论的预测最为相符，根据该理论，大脑不对称被视为相对而非绝对的，任何一个半球都能够处理任何一种材料（语言或视觉空间），但效率水平不同。然而，尽管之前已表明，当单独呈现刺激材料时，它们会在预测方向上产生稳定且一致的侧向不对称，但在复合的、整合性的匹配任务中，名字的位置似乎是产生不对称的主要决定因素。因此，似乎当要对这类刺激进行交叉匹配时，要么左半球（语言）加工以某种方式主导右半球（视觉空间）加工（尽管并非以简单的激活/注意理论所预测的方式），要么左半球更强的能力占主导。
