在这项研究中，我们探讨了语义痴呆患者短期言语记忆三个不同方面的能力。正如预期的那样，通过立即连续回忆单词列表来评估，这两名患者对词汇语义项目信息的记忆力很差。相比之下，他们对语音信息的短期记忆得到了保留，这可以通过立即连续回忆非单词列表的正常表现来证明，非单词语音频率效应正常或增加，并且在延迟探测识别任务中对语音诱饵的敏感性增加。此外，患者似乎对列表中单词的顺序有很好的记忆力。这些数据进一步支持了以下观点：语言知识是言语 STM 能力的主要决定因素，但它们也强调了项目和顺序回忆所涉及的过程的必要区别，正如最近的 STM 模型所提出的那样。
In this study, we explored capacities for three different aspects of short-term verbal memory in patients with semantic dementia. As expected, the two patients had poor recall for lexico-semantic item information, as assessed by immediate serial recall of word lists. In contrast, their short-term memory for phonological information was preserved, as evidenced by normal performance for immediate serial recall of nonword lists, with normal or increased nonword phonotactic-frequency effects, and increased sensitivity to phonological lures in a delayed probe recognition task. Furthermore, the patients appeared to have excellent memory for the serial order of the words in a list. These data provide further support for the proposal that language knowledge is a major determining factor of verbal STM capacity, but they also highlight the necessary distinction of processes involved in item and order recall, as proposed by recent models of STM.
