Naming of two semantically impaired aphasic patients was treated with the contextual repetition priming technique, which involves repeated repetition of names of pictures that are related semantically, phonologically, or are unrelated. Our previous studies using this technique have suggested that patients with impaired access to lexical-semantic representations benefit in the short-term from this treatment technique, but show no long-term improvement in naming. In contrast, patients with good access to semantics show short- and long-term benefits from this treatment. Here we report two studies of treatment for two individuals with aphasia affecting access to lexical semantics and anomia but spared access to input and output phonology and spared conceptual semantics. We predicted that they would show short-term facilitation from the contextual priming, but no long-term improvements in naming. The results confirmed the prediction. An account of this pattern is offered within the framework of an interactive activation model of word retrieval. Additionally, we discuss alternative techniques for addressing naming deficits when access to semantics is impaired.
两名语义受损失语症患者的命名采用情境重复启动技术进行治疗，该技术涉及对语义相关、语音相关或无关的图片名称进行重复。我们之前使用该技术的研究表明，词汇语义表征获取受损的患者在短期内会从这种治疗技术中受益，但在命名方面没有长期改善。相比之下，语义获取良好的患者在短期和长期内都能从这种治疗中受益。在这里，我们报告了两项针对两名失语症患者的治疗研究，这两名患者影响词汇语义获取和命名，但输入和输出语音以及概念语义未受影响。我们预测他们会在情境启动中表现出短期促进作用，但在命名方面不会有长期改善。结果证实了这一预测。在单词检索的交互式激活模型框架内对这种模式进行了解释。此外，我们还讨论了在语义获取受损时解决命名缺陷的替代技术。
