Neuropsychological research indicates that the left hemisphere plays a dominant role in verbal production and processing, while the right hemisphere plays a dominant role in nonverbal production and processing. This study sought to examine the effects of such differential hemispheric specialization on personality and social competency. Ten left hemisphere damaged (LHD) stroke patients, 11 right hemisphere damaged (RHD) stroke patients, and 7 neurologically normal (NHD) patients were videotaped while engaging in social interaction with their spouse and an interviewer. Segments of the interactions were independently coded by two observers. Patients and spouses were rated with respect to their level of social competency and the extent to which they were characterized by 10 personality adjectives (e.g., outgoing, warm). Ratings for the personality items were summed to create an aggregate score. Analysis of these scores revealed both LHD and RHD patients to have lower (i.e., more negative) mean scores than NHD patients, suggesting that stroke patients as a whole were seen as socially impaired. Analysis of the socially competent item revealed particular LHD deficits; LHD patients were seen as less socially competent than both RHD and NHD patients. Spouses of LHD, RHD, and NHD patients, in contrast, did not differ in observer-rated social behavior.
神经心理学研究表明，左半球在言语产生和加工中起主导作用，而右半球在非言语产生和加工中起主导作用。本研究旨在考察这种半球功能差异对人格和社会能力的影响。对10名左半球损伤（LHD）的中风患者、11名右半球损伤（RHD）的中风患者和7名神经功能正常（NHD）的患者进行录像，记录他们与配偶及一名访谈者的社交互动。互动片段由两名观察者独立编码。对患者及其配偶的社会能力水平以及他们在10个个性形容词（如外向、热情）方面的特征程度进行评分。将个性项目的评分相加得出总分。对这些分数的分析显示，LHD和RHD患者的平均得分均低于NHD患者（即得分更低），这表明中风患者总体上被认为存在社交障碍。对社交能力项目的分析揭示了LHD患者的特定缺陷；LHD患者被认为社交能力低于RHD患者和NHD患者。相比之下，LHD、RHD和NHD患者的配偶在观察者评定的社交行为方面没有差异。
