The purpose of this study was to investigate communicative effectiveness in aphasia. Five patients with Broca's aphasia and five neurologically normal subjects participated in referential communication and spontaneous conversation tasks. Performance on the referential tasks was used to derive measures of communication success, learning, and efficiency. A representative sample of utterances from the referential tasks and 100 utterances from the spontaneous conversation task also were analyzed to determine the frequency of operationally defined errors in speech, lexical access, grammar, content, discourse, and use. Results suggest that patients with Broca's aphasia retain communicative effectiveness in the presence of significant speech and language deficits and experimentally imposed constraints on the use of visual and gestural communication modalities.
本研究的目的是调查失语症患者的沟通有效性。五名布罗卡失语症患者和五名神经功能正常的受试者参与了指称性沟通和自发对话任务。指称性任务的表现被用于得出沟通成功率、学习能力和效率的测量指标。还对指称性任务中话语的代表性样本以及自发对话任务中的100条话语进行了分析，以确定语音、词汇提取、语法、内容、语篇和使用方面操作性定义错误的频率。结果表明，布罗卡失语症患者在存在明显的言语和语言缺陷以及实验性施加的视觉和手势交流方式使用限制的情况下，仍能保持沟通有效性。
