摘要我们提出了一个病人的短期记忆障碍的情况下。BO具有缩短的跨度（2至3个项目），在自由回忆中没有近因效应，并且在Brown-Peterson任务中快速遗忘，使她成为短期言语记忆功能受损的患者。她在听觉或书面单词列表的回忆中没有表现出语音相似性或单词长度的影响，但在从端回忆条件下存在一些近因效应，并且在未填充的情况下比在填充的情况下在布朗-彼得森任务中表现得更好。这种表演模式被解释为与STM发音排练过程的主要干扰一致可能还有语音存储的一些损伤（使用Baddeley 1986年的术语）。她的失语症--言语失用症--也与发音排练的障碍相一致。BO显示保留的能力，从打印中提取音位，包括应用亚词汇字素音素对应的能力，从而ind.
Abstract We present a case of a patient with a disorder of short-term memory. BO has a reduced span (2 to 3 items), no recency effect in free recall, and rapid forgetting in Brown-Peterson tasks, establishing her as a patient with impaired short-term verbal memory functions. She shows no effect of either phonological similarity or word length in recall of auditory or written word lists, but some recency effect under recall-from-end conditions and better performance on Brown-Peterson tasks in an unfilled than in a filled condition. This pattern of performance is interpreted as being consistent with a primary disturbance of the articulatory rehearsal processes of S.T.M. and possibly some impairment of the phonological store (using Baddeley's 1986 terminology). Her aphasic disturbance—apraxia of speech—is also consistent with a disturbance of articulatory rehearsal. BO shows a retained ability to extract phonology from print, including an ability to apply sublexical grapheme-phoneme correspondences, thus ind...
