This study investigated the impact of right cerebral hemisphere damage on the capacity to take shared responsibility for the development of an intentional structure in conversation. Intentions are important determiners of both discourse structure and utterance meaning in context. Right-hemisphere damaged (RHD) individuals have been reported to have difficulty in the use of prosody as well as performing and appreciating the process of discourse tailoring which is dependent on recognizing speakers intentions. Audio taped samples of naturalistic conversations between RHD individuals and normal speakers were analysed. Text-level discourse processing analyses involved measures of global discourse structure and self-monitoring accuracy. Prosodic analyses included fundamental frequency (F0) resetting, pause durations and inter-turn intervals. The results revealed that speakers with right cerebral hemisphere damage do not, first, use prosody to alert listeners to changes in discourse structure, and, second, assume equal responsibility for the development and maintenance discourse structure.
本研究调查了右脑半球损伤对在对话中为构建意图结构承担共同责任的能力的影响。意图是语境中话语结构和话语意义的重要决定因素。据报道，右脑损伤（RHD）个体在韵律运用方面存在困难，并且在进行和理解依赖于识别说话者意图的话语调整过程方面也有困难。对RHD个体与正常说话者之间的自然对话录音样本进行了分析。文本层面的话语处理分析涉及全局话语结构和自我监测准确性的测量。韵律分析包括基频（F0）重置、停顿时长和轮次间隔。结果显示，右脑半球损伤的说话者，其一，不会利用韵律向听众提示话语结构的变化；其二，在话语结构的构建和维持中承担的责任并不相同。
