Disorders in nonverbal communication of emotion have been documented in patients with right hemisphere pathology; lexical expression of emotion is virtually unstudied. In this preliminary investigation, emotionally laden slides were used to elicit discourse from right brain-damaged (RBD), left brain-damaged (LBD), and normal control (NC) subjects. New techniques were developed to examine the ability of these subjects to express emotion in words; formalistic and pragmatic analyses of the discourse were conducted. RBDs, relative to NCs and LBDs, were less successful in using words to convey emotion and produced words of lower emotional intensity. LBD aphasics, despite their linguistic deficits, were comparable to NCs in conveying emotional valence. The data tend to support the speculation that the right hemisphere is dominant for lexical expression of emotion. This study has implications for the neuropsychological investigation of language, emotion, and the brain.
情感的非言语交流障碍在右脑病变患者中已有记录；而情感的词汇表达几乎未被研究。在这项初步调查中，使用充满情感的幻灯片来引发右脑损伤（RBD）、左脑损伤（LBD）和正常对照（NC）受试者的话语。开发了新技术来检查这些受试者用言语表达情感的能力；对话语进行了形式主义和语用分析。与NC组和LBD组相比，RBD组在使用词汇传达情感方面不太成功，且所产生词汇的情感强度较低。LBD失语症患者尽管存在语言缺陷，但在传达情感效价方面与NC组相当。这些数据倾向于支持右脑在情感词汇表达中占主导地位的推测。这项研究对语言、情感和大脑的神经心理学研究具有启示意义。
