This study examines the effect of emotional content on the verbal pragmatic aspects of discourse production in right-brain-damaged (RBD), left-brain-damaged (LBD), and normal control (NC) right-handed adults. Subject groups were matched for gender, age, education, and occupation; brain-damaged groups did not differ on months post CVA onset and lesion location. Subjects were screened to ensure that they demonstrated adequate cognitive and visual perceptual skills to participate in the study. Pictorial stimuli were used to elicit discourse that contained emotional and nonemotional (procedural, visuospatial) content. Trained raters evaluated each discourse for appropriateness on seven verbal pragmatic features (e.g., conciseness, quantity, relevancy). Across all three conditions, the brain-damaged groups were impaired relative to NCs. In the nonemotional conditions, LBDs were particularly impaired in pragmatics, whereas in the emotional condition, RBDs demonstrated pragmatic deficits. Emotional content appeared to facilitate pragmatic performance among LBD aphasics and to suppress pragmatic performance among RBDs.
本研究考察了情感内容对右脑损伤（RBD）、左脑损伤（LBD）及正常对照（NC）的右利手成年个体话语产出的言语语用方面的影响。研究对象按性别、年龄、教育程度和职业进行匹配；脑损伤组在中风发作后的月份数和损伤位置方面无差异。对研究对象进行筛查，以确保他们具备足够的认知和视觉感知技能来参与研究。使用图片刺激来引发包含情感和非情感（程序性、视觉空间）内容的话语。经过训练的评分者根据七个言语语用特征（如简洁性、信息量、相关性）对每段话语的恰当性进行评估。在所有三种情况下，脑损伤组相对于正常对照组都存在损伤。在非情感情况下，左脑损伤者在语用方面尤其受损，而在情感情况下，右脑损伤者表现出语用缺陷。情感内容似乎促进了左脑损伤失语症患者的语用表现，并抑制了右脑损伤者的语用表现。
