PurposeWe调查从理论上动机的角度来看，什么信息区分足够的人与aphasia.Method21名成年人失语症随之而来的单左半球中风的对象提供的描述不足的描述9生活和9非生活对象。对响应的准确性进行评分（即，充分性），并记录所提供的语义特征信息的类型和数量。主效应和相互作用，确定使用重复测量方差分析，与重大发现跟进与计划comparison.ResultsDifferences正确和不正确的描述之间的差异被确定为两个功能类型和功能的独特性为生活和非生活项目，特别是突出了两个领域描述中区别特征的重要性。结论这些发现增加了相对较少的研究失语症成人语义特征加工的文献。这是一个关键的差距时，考虑到优势的语义为基础的治疗中风失语症的词检索障碍。我们的研究结果提供了初步支持的概念，语义引导治疗中风失语症的词检索障碍可能是面向增加语义迂回的特异性，以增加语义自我提示，并改善信息交流的对话伙伴。
PurposeWe investigated from a theoretically motivated perspective what information differentiated sufficient from insufficient descriptions of objects provided by persons with aphasia.MethodTwenty-one adults with aphasia consequent to single left-hemisphere stroke verbally described 9 living and 9 nonliving objects. Responses were scored for accuracy (i.e., sufficiency) and tallied for type and quantity of semantic feature information provided. Main effects and interactions were identified using repeated measures analyses of variance, with significant findings followed up with planned comparisons.ResultsDifferences between correct and incorrect descriptions were identified with respect to both feature type and feature distinctiveness for living and nonliving items, in particular highlighting the importance of distinctive features in descriptions of both domains.ConclusionsThese findings add to the relatively small body of literature investigating semantic feature processing in adults with aphasia. This is a critical gap to close when considered in light of the preponderance of semantically based treatments for word-retrieval impairment in stroke-aphasia. Our findings provide preliminary support for the notion that semantically guided treatments for word-retrieval impairment in stroke-aphasia may be geared toward increasing specificity of semantic circumlocution to increase semantic self-cueing and to improve communication of information to conversation partners.
