This study examined hemispheric specialization for discourse reports of emotional and nonemotional experience in 16 right-brain-damaged (RBD), 16 left-brain-damaged (LBD), and 16 demographically-matched normal control (NC) right-handed adults. Patient groups did not differ on etiology, months post-CVA onset, and intrahemispheric lesion location. Subjects were requested to produce monologues about positive and negative emotional and nonemotional experiences. The lexical content of written transcriptions of these monologues was later rated for "emotionality" by naive judges. Overall, RBDs described experiences with less emotional intensity than did NCs and LBDs, providing support for right hemisphere involvement in lexical emotion. Although the RBDs in the current study demonstrated similar patterns of deficits in a prior study [9] on tasks involving lexical emotional perception, there were no significant relationships between the current measures of emotional expression and the previous measures of emotional perception. Finally, the expression and the perception data were examined with respect to intrahemispheric factors. Among the brain-damaged subjects, subcortical structures were more involved in reports of emotional experience, and cortical structures were more involved in the perception of emotion.
本研究调查了16名右脑损伤(RBD)、16名左脑损伤(LBD)以及16名人口统计学特征匹配的正常对照(NC)的右利手成年人在情感和非情感体验的话语报告中的半球特化情况。患者组在病因、中风发作后的月数以及半球内病变位置方面没有差异。要求受试者就积极和消极的情感及非情感体验进行独白。这些独白的书面转录本的词汇内容随后由外行评判员进行“情感性”评分。总体而言,右脑损伤患者描述的体验的情感强度低于正常对照和左脑损伤患者,这为右脑参与词汇情感表达提供了支持。尽管本研究中的右脑损伤患者在先前一项关于词汇情感感知任务的研究[9]中表现出类似的缺陷模式,但当前情感表达测量与先前情感感知测量之间没有显著关系。最后,针对半球内因素对表达和感知数据进行了检查。在脑损伤受试者中,皮层下结构更多地参与情感体验报告,而皮层结构更多地参与情感感知。
