An interaction between semantic memory and prosody contributes to phonological working memory functioning

语义记忆对言语短期记忆的影响已经得到了广泛的认识，而言语短期记忆的评价通常是根据记忆中语音的准确性来进行的。单词回忆实验表明，语义变量的实验操作也会影响超分段音系（日语的音高重音）的回忆准确性，而语义对短期记忆任务的影响又会受到音高重音操作的影响。这些结果表明，在短期记忆中，音高重音和语义之间有很强的相互作用。相比之下，音高重音操作（即重音典典性）和音素序列操作（即语音定向频率）在日语非词序列记忆任务中显示出非常有限的相互作用。这些数据表明，语音工作记忆中音素序列的保留受到超音段音素知识的影响，而语义记忆可以调解两者之间的联系。

It has been widely recognized that semantic memory contributes to verbal short-term memory performance, which is usually assessed in terms of the accuracy of segmental phonology in recall. Word recall experiments showed that recall accuracy in suprasegmental phonology (pitch accent in Japanese) was also affected by experimental manipulations of semantic variables and that the effect of semantics on short-term memory tasks was, in turn, influenced by manipulations of pitch accents. These results suggest a strong interaction between pitch accent and semantics in short-term memory. In contrast, pitch accent manipulation (i.e., accent typicality) and phoneme sequence manipulation (i.e., phonotactic frequency) showed a very limited interaction in Japanese nonword serial recall tasks. These data suggest that the retention of phoneme sequences in phonological working memory is influenced by knowledge about suprasegmental phonology when semantic memory can mediate a link between them.
