Previous studies investigating hemispheric organization for processing concrete and abstract nouns have provided conflicting results. Using manual reaction time tasks some studies have shown that the right hemisphere is capable of analyzing concrete words but not abstract. Others, however, have inferred that the left hemisphere is the sole analyzer of both types of lexicon. The present study tested these issues further by measuring vocal reaction times of normal subjects to unilaterally presented concrete and abstract items. Results were consistent with a model of functional localization which suggests that the minor hemisphere is capable of differentially processing both types of lexicon in the presence of a dominant left hemisphere.
以往关于大脑半球处理具体名词和抽象名词的组织方式的研究得出了相互矛盾的结果。一些使用手动反应时任务的研究表明，右半球能够分析具体词汇，但不能分析抽象词汇。然而，其他研究则推断左半球是这两种词汇类型的唯一分析器。本研究通过测量正常受试者对单侧呈现的具体和抽象词汇的语音反应时，进一步检验了这些问题。结果与功能定位模型一致，该模型表明，在左半球占主导的情况下，次要半球能够对这两种词汇类型进行差异处理。
