背景唐氏综合症（DS）患者的听觉短期记忆跨度比非语言心理年龄（MA）短得多。本研究通过使用斯坦福-比奈的句子记忆子测试评估了巴德利模型的主张，即言语短期记忆缺陷可能是由于较慢的语速（因此在 2 秒被动存储中排练的材料较少）引起的。之前的研究表明，对于 DS 和语言匹配的参与者，数字广度回忆的说话速度与考官的慢速（每秒一个音节）相当。 方法 将 30 名 DS 个体与两个对照组（非语言 MA 匹配和平均话语长度 (MLU) 匹配）的句子跨度和最长逐字回忆句子的语速进行比较。句子刺激以正常的语速呈现。结果 DS 组的句子记忆广度比 MA 匹配组更短，并且比 MLU 匹配对照组更快而不是更慢的语速（每秒音节数）。结论 语言产生水平在 DS 组句子记忆广度差异中占了很大一部分。因此，语言表达能力，而不是说话速度，可以预测言语记忆广度的变化。
BackgroundIndividuals with Down's syndrome (DS) have an auditory short‐term memory span disproportionately shorter than the non‐verbal mental age (MA). This study evaluated the Baddeley model's claim that verbal short‐term memory deficits might arise from slower speaking rates (and thus less material rehearsed in a 2 s passive store) by using the sentence memory subtest of the Stanford‐Binet. Previous work had shown digit span recall speaking rate to be comparable to the examiner's slow rate (one syllable per second) for both DS and language‐matched participants.MethodThirty individuals with DS were compared to two control groups [non‐verbal MA‐matched and mean length of utterance (MLU)‐matched] on the sentence span and speaking rate for the longest verbatim recalled sentence. Sentence stimuli were presented at a normal speaking rate.ResultsThe DS group had shorter sentence memory span than the MA‐matched group and a faster, rather than slower, speaking rate (syllables per second) than the MLU‐matched controls.ConclusionsLanguage production level accounted for a substantial portion of the variance in the sentence memory span in the DS group. Thus, language production skill, rather than speaking rate, predicts variability in verbal memory span.
