Three experiments were conducted to investigate the verbal performance of the right cerebral hemisphere in right-handed individuals with normal intact brains. A manual reaction time (RT) measure was used to assess the relative efficiency of lateral stimulus-response pathways (e.g., left visual field-right hemisphere-left hand) in processing linguistic information. Experiment 1 showed that the right and left hemispheres were equally efficient at recognizing concrete object nouns in a lexical decision task. The RT data also suggested that abstract nouns may be recognized only by the left hemisphere. Experiments 2 and 3 demonstrated the right hemisphere's ability to detect semantic relationships between concrete nouns and their superordinate categories. The findings were discussed in terms of their consistency with data from split-brain research and their implications for models of the functional organization of language skills in the normal brain. It was proposed that the right hemisphere in the intact brain can play a functional role in processing language.
进行了三项实验，以研究大脑正常完整的右利手个体右脑半球的言语表现。采用手动反应时（RT）测量法，评估在处理语言信息时，外侧刺激-反应通路（例如，左视野-右脑半球-左手）的相对效率。实验1表明，在词汇判断任务中，右脑半球和左脑半球在识别具体物体名词方面效率相当。反应时数据还表明，抽象名词可能仅由左脑半球识别。实验2和实验3证明了右脑半球检测具体名词与其上级类别之间语义关系的能力。根据这些发现与裂脑研究数据的一致性及其对正常大脑语言技能功能组织模型的意义进行了讨论。有人提出，完整大脑中的右脑半球在语言处理中可以发挥功能作用。
