The effect of typicality of category exemplars on naming was investigated using a single subject experimental design across participants and behaviors in 4 patients with fluent aphasia. Participants received a semantic feature treatment to improve naming of either typical or atypical items within semantic categories, while generalization was tested to untrained items of the category. The order of typicality and category trained was counterbalanced across participants. Results indicated that patients trained on naming of atypical exemplars demonstrated generalization to naming of intermediate and typical items. However, patients trained on typical items demonstrated no generalized naming effect to intermediate or atypical examples. Furthermore, analysis of errors indicated an evolution of errors throughout training, from those with no apparent relationship to the target to primarily semantic and phonemic paraphasias. Performance on standardized language tests also showed changes as a function of treatment. Theoretical and clinical implications regarding the impact of considering semantic complexity on rehabilitation of naming deficits in aphasia are discussed.
采用单一被试实验设计，对4名流利性失语症患者的类别样例典型性对命名的影响进行了跨参与者和行为的研究。参与者接受语义特征治疗，以改善语义类别中典型或非典型项目的命名，同时对该类别的未训练项目进行泛化测试。典型性和训练类别的顺序在参与者之间进行了平衡。结果表明，接受非典型样例命名训练的患者表现出对中间和典型项目命名的泛化。然而，接受典型项目训练的患者对中间或非典型示例没有表现出泛化命名效应。此外，错误分析表明，在整个训练过程中错误有所演变，从与目标没有明显关系的错误到主要是语义和音素性错语。标准化语言测试的表现也显示出随治疗而变化。讨论了考虑语义复杂性对失语症命名缺陷康复影响的理论和临床意义。
