目的：本研究的目的是系统地检查与语义特征分析相关的结果，语义特征分析是失语症中单词提取缺陷的既定治疗方法。属性的实验设计和刺激被操纵，以评估语义相关和不相关的项目的广义命名。此外，本研究旨在探讨生产的语义信息的变化。方法：语义特征分析的背景下，应用多基线设计与5人慢性失语症。实验项目的语义类别成员资格，命名尝试的次数，并提供项目名称进行控制。收购，推广和维护的影响进行了测量，在探针的命名性能。生产的语义信息也测量实验项目和话语tasks.Results：治疗与系统的增加命名的训练项目的5名参与者中的4。积极推广到未经训练的样本的训练类别被发现重复曝光的项目，但不是有限的曝光项目。轻微增加生产的语义contentsobserved.Conclusion：重复尝试命名未处理的项目似乎在泛化中发挥作用。提供未训练项目的名称可能增强了2名参与者的一般反应。
Purpose: The purpose of this investigation was to systematically examine outcomes associated with Semantic feature analysis, which is an established treatment for word-retrieval deficits in aphasia. Attributes of the experimental design and stimuli were manipulated to evaluate generalized naming of semantically related and unrelated items. In addition, the study was designed to examine changes in production of semantic information.Method: Semantic feature analysis was applied in the context of multiple-baseline designs with 5 persons with chronic aphasia. Experimental items were controlled for semantic category membership, number of naming attempts, and provision of item names. Acquisition, generalization, and maintenance effects were measured in probes of naming performance. Production of semantic information was also measured in response to experimental items and in discourse tasks.Results: Treatment was associated with systematic increases in naming of trained items for 4 of the 5 participants. Positive generalization to untrained exemplars of trained categories was found for repeatedly exposed items but not for limited-exposure items. Slight increases in production of semantic content were observed.Conclusion: Repeated attempts to name untreated items appeared to play a role in generalization. Provision of the names of untrained items may have enhanced generalized responding for 2 participants.
