To investigate differences between a group with mild traumatic brain injury (MTBI) and a control group relative to standard scores and error type during word retrieval in both naming and discourse tasks.
Ten participants with MTBI were age-, gender- and education-matched with 10 participants without injury. Pre-experimental tasks for the participants with MTBI included the Scales of Cognitive Ability for Traumatic Brain Injury and the Raven's Coloured Progressive Matrices and both groups received the Peabody Picture Vocabulary Test-III. Experimental tasks included the Test of Adolescent/Adult Word Finding and the Test of Word Finding in Discourse.
Few participants (three on each experimental task) demonstrated psychometrically-based word retrieval deficits (standard score < 85); however, a significant difference in performance for the TAWF as compared to the TWFD was observed between groups. More word finding errors occurred with confrontational naming than with discourse tasks for both groups, with latency as the primary error type.
Confrontational naming tasks may be more sensitive to subtle language difficulties occurring after MTBI. The study of adults with MTBI and their performance on semantically-based tasks offers important information for the advancement of therapeutic intervention and education.
研究轻度创伤性脑损伤（MTBI）组与对照组在命名和语篇任务中单词检索的标准分数和错误类型方面的差异。
10名MTBI参与者在年龄、性别和教育程度上与10名未受伤参与者相匹配。MTBI参与者的实验前任务包括创伤性脑损伤认知能力量表和瑞文彩色渐进矩阵测验，两组均接受皮博迪图片词汇测验第三版。实验任务包括青少年/成人单词查找测试和语篇中的单词查找测试。
很少有参与者（每个实验任务各有3名）表现出基于心理测量的单词检索缺陷（标准分数<85）；然而，两组之间观察到TAWF与TWFD在表现上存在显著差异。两组在对抗性命名中出现的单词查找错误都比在语篇任务中多，延迟是主要的错误类型。
对抗性命名任务可能对MTBI后出现的细微语言困难更敏感。对患有MTBI的成年人及其在基于语义的任务中的表现进行研究，为治疗干预和教育的发展提供了重要信息。
