Much controversy surrounds the language production abilities of traumatically head-injured adults. In this study, the narrative skills of head-injured and normal adults are examined and compared on the amount, rate, and distribution of information in a picture description task. The head-injured adults, all of whom were at least six months postinjury, were found to be similar to the normals in the amount of pertinent content expressed, narrative length, and rate of speech in the given narrative task; however, they were found to be significantly slower in the rate of information imparted. This decreased efficiency of communication was related to the head-injured adults' lengthier and slower verbal outputs. They required relatively more words and time to convey the essential information. Finally, several clinical implications are raised concerning the use of narrative tasks in head-injured rehabilitation.
外伤性脑损伤成年患者的语言表达能力存在诸多争议。在本研究中，通过图片描述任务中的信息数量、速度和分布，对脑损伤成年患者和正常成年患者的叙事技巧进行了检查和比较。所有脑损伤成年患者均在受伤至少六个月后接受测试，结果发现，在给定的叙事任务中，他们在表达的相关内容数量、叙事长度和语速方面与正常人相似；然而，他们传递信息的速度明显较慢。这种沟通效率的降低与脑损伤成年患者冗长且缓慢的语言输出有关。他们需要相对更多的词汇和时间来传达关键信息。最后，针对叙事任务在脑损伤康复中的应用提出了一些临床意义。
