成语解释任务通常用于成人脑损伤的临床评估，成语加工在心理语言学文献中受到越来越多的关注。临床证据表明，患有单侧右半球损伤（RHD）的成年人对习惯表达和其他比喻形式所传达的非字面意义不敏感。然而，这种描述是来自他们对反映心理操作多个方面的任务的终端反应（离线测量），掩盖了表现不佳的根源。本研究采用在线词汇监测任务，考察了RHD、左半球受损和正常老化的成年人对熟悉习语的内隐知识。大脑受损的受试者在这项任务上的表现与正常对照组相似，尽管临床受试者在离线习语定义测量上的表现较差。这些结果表明，单侧脑损伤的成年人可以激活和检索熟悉的习语形式，他们的习语解释缺陷很可能反映了信息处理后期的损伤。此外，错误的成语定义的性能分析不支持习惯的RHD成人过分的文字反应器的特性。本文讨论了成语解释任务的性质和使用的临床意义。
Idiom interpretation tasks are routinely used in the clinical evaluation of adults with brain damage, and idiom processing has received increasing attention in the psycholinguistic literature. Clinical evidence suggests that adults with unilateral right-hemisphere damage (RHD) are insensitive to nonliteral meanings conveyed by idiomatic expressions and other figurative forms. However, this portrayal is derived from their terminal responses to tasks that reflect multiple aspects of mental operations (off-line measures), obscuring the source of poor performance. This study used an on-line word-monitoring task to assess RHD, left-hemisphere-damaged, and normally aging adults' implicit knowledge of familiar idiomatic expressions. Brain-damaged subjects performed similarly to normal controls on this task, even though the clinical subjects fared poorly by comparison on an off-line idiom definition measure. These results suggest that adults with unilateral brain damage can activate and retrieve familiar idiomatic forms, and that their idiom-interpretation deficits most likely reflect impairment at some later stage of information processing. Further, error analysis of idiom-definition performance did not support the customary characterization of RHD adults as excessively literal responders The paper discusses clinical implications of the nature and use of idiom interpretation tasks.
