我们研究了语义合理性和句法复杂性是否影响潜在失语症和失语症患者的即时句子回忆。迄今为止，尚未在这些类型的失语症中探索这些因素。与之前的句子回忆研究一样，我们测量了逐字回忆的准确性和独特的实时语音测量。结果表明，准确性并不能区分潜在失语症和神经典型对照之间的表现。然而，一些实时言语测量可以区分潜在失语症患者和神经正常对照者之间的表现。有一些证据（尽管并不普遍）表明语义的合理性和句法的复杂性影响了回忆表现。语义合理性和句法复杂性之间没有相互作用。潜在失语症患者准备反应的速度比对照组慢；失语症患者的速度也比潜伏组和对照组慢。看来，在潜在失语症和失语症中，以时间言语测量为索引的处理速度可能会受到不同程度的损害。然而，语义合理性和句法复杂性并没有显示出各组之间明确的表现模式。尽管缺乏交互作用，我们还是基于概念性短期记忆提出了一种解释，解释为什么语义上不可信的句子通常更错误，而且回忆起来也可能更慢。
We investigated whether semantic plausibility and syntactic complexity affect immediate sentence recall in people with latent and anomic aphasia. To date, these factors have not been explored in these types of aphasia. As with previous studies of sentence recall, we measured accuracy of verbatim recall and uniquely real-time speech measures. The results showed that accuracy did not distinguish performance between latent aphasia and neurotypical controls. However, some of the real-time speech measures distinguished performance between people with latent aphasia and neurotypical controls. There was some evidence, though not pervasive, that semantic plausibility and syntactic complexity influenced recall performance. There were no interactions between semantic plausibility and syntactic complexity. The speed of preparation of responses was slower in latent aphasia than controls; it was also slower in anomic aphasia than both latent and control groups. It appears that processing speed as indexed by temporal speech measures may be differentially compromised in latent and anomic aphasia. However, semantic plausibility and syntactic complexity did not show clear patterns of performance among the groups. Notwithstanding the absence of interactions, we advance an explanation based on conceptual short-term memory as to why semantically implausible sentences are typically more erroneous and possibly also slower in recall.
