The purpose of this study was to determine if discourse macrolevel processing abilities differed between children with severe traumatic brain injury (TBI) at least 2 years postinjury and typically developing children. Twenty-three children had sustained a severe TBI either before the age of 8 (n = 10) or after the age of 8 (n = 13). The remaining 32 children composed a control group of typically developing peers. The groups' summaries and interpretive lesson statements were analyzed according to reduction and transformation of narrative text information. Compared to the control group, the TBI group condensed the original text information to a similar extent. However, the TBI group produced significantly less transformed information during their summaries, especially those children who sustained early injuries. The TBI and control groups did not significantly differ in their production of interpretive lesson statements. In terms of related skills, discourse macrolevel summarization ability was significantly related to problem solving but not to lexical or sentence level language skills or memory. Children who sustain a severe TBI early in childhood are at an increased risk for persisting deficits in higher level discourse abilities, results that have implications for academic success and therapeutic practices.
本研究的目的是确定重度创伤性脑损伤(TBI)儿童在受伤至少两年后与正常发育儿童在语篇宏观层面处理能力上是否存在差异。23名儿童曾遭受重度TBI,其中8岁之前受伤的有10名,8岁之后受伤的有13名。其余32名儿童组成了一个由正常发育同龄人构成的对照组。根据叙事文本信息的缩减和转换对两组的总结及解释性课程陈述进行了分析。与对照组相比,TBI组对原文信息的浓缩程度相似。然而,TBI组在总结过程中产生的转换信息明显较少,尤其是那些早期受伤的儿童。TBI组和对照组在解释性课程陈述的生成方面没有显著差异。在相关技能方面,语篇宏观层面的总结能力与问题解决显著相关,但与词汇或句子层面的语言技能或记忆无关。儿童期早期遭受重度TBI的儿童在更高层次语篇能力方面持续存在缺陷的风险增加,这一结果对学业成就和治疗实践具有启示意义。
