理性适应的信息理论原则预测，失语症患者通过更多地依赖相对未受损的非语言知识进行交流来适应他们的语言障碍。通过评估与年龄匹配的神经型对照组相比，左半球中风所致慢性失语症成人在动词提取过程中更多地依赖概念信息而不是词汇信息的程度，对这一预测进行了研究。启动动词命名任务检查的促进程度，每个参与者组收到的概念事件相关或词汇搭配线索，相比无关的基线线索。结果提供的证据表明，成年失语症患者的概念线索相比，控制放大促进，而健康的控制收到更大的促进词汇线索。这表明，适应替代和相对未受损的信息可能有助于成功的失语症的词提取。模型的合理适应和临床神经康复的影响进行了讨论。
The information theoretic principle of rational adaptation predicts that individuals with aphasia adapt to their language impairments by relying more heavily on comparatively unimpaired non-linguistic knowledge to communicate. This prediction was examined by assessing the extent to which adults with chronic aphasia due to left-hemisphere stroke rely more on conceptual rather than lexical information during verb retrieval, as compared to age-matched neurotypical controls. A primed verb naming task examined the degree of facilitation each participant group received from either conceptual event-related or lexical collocate cues, compared to unrelated baseline cues. The results provide evidence that adults with aphasia received amplified facilitation from conceptual cues compared to controls, whereas healthy controls received greater facilitation from lexical cues. This indicates that adaptation to alternative and relatively unimpaired information may facilitate successful word retrieval in aphasia. Implications for models of rational adaptation and clinical neurorehabilitation are discussed.
