我们报告了一项调查的短期记忆STM损伤的15名失语症患者的语言配置文件不同的相对参与词汇语义和语音过程。基于短时记忆依赖于语言加工的内在能力这一假设，重复广度的变化应与词汇语义和语音障碍相关：具体而言，当词汇语义加工受损时，语音能力为广度表现提供了主要支持;当语音加工受损时，应该增加对词汇语义信息的依赖。支持这一假设的相关措施的语义和语音能力的影响imagertium和频率的重复性能，并与串行位置的影响，在一个词和字符串内的音素检索。的数据进行了讨论的语言处理的交互式激活模型的框架内。
We report an investigation of the short-term memory STM impairments of 15 aphasic subjects whose language profiles varied with respect to the relative involvement of lexical-semantic and phonological processes. On the hypothesis that STM is dependent on capacities intrinsic to language processing, repetition span should vary in conjunction with lexical-semantic and phonological impairment: Specifically, when lexical-semantic processing is impaired, phonological abilities provide primary support to span performance; when phonological processing is impaired, there should be increased reliance on lexical-semantic information. Support for this hypothesis was provided by correlating measures of semantic and phonological abilities with effects of imageability and frequency on repetition performance, and with serial position effects in retrieval of phonemes within a word and words within a string. The data are discussed within the framework of an interactive activation model of language processing.
