非文字记忆广度的发展性增长与改进计算率（AR）和项目识别时间（IT）相关。在不同的理论解释中，AR反映了发音排练循环的效率，而IT反映了中央工作空间的可用性。在本研究中，IT和AR作为一个，两个和三个音节的口语单词的记忆广度的预测5岁，8岁和11岁的儿童进行了比较。结果表明，广度随年龄和词长的变化均呈线性函数关系，但广度与信息量之间不存在等价关系;当发音抑制阻止复述时，广度对词长的敏感性大大降低。这些研究结果表明，随着年龄和单词长度的跨度的变化是由于排练，而不是一个中央工作区的可用性。然而，抑制并没有减少跨度的年龄差异，这表明排练以外的发展过程也很重要。
Developmental increases in verbal memory span are correlated with improvements culation rate (AR) and item identification time (IT). In different theoretical accounts, AR reflects the efficiency of an articulatory rehearsal loop, while IT reflects the availability of a central workspace. In the present study, IT and AR were compared as predictors of memory span for spoken words of one, two and three syllables in children aged 5, 8 and 11. The results showed that a linear function described the variation of span with both age and word-length but there was no equivalent relationship between span and IT. The sensitivity of span to word-length was much reduced when rehearsal was prevented by articulatory suppression. These findings suggest that variation of span with age and word-length is attributable to rehearsal rather than the availability of a central workspace. However, suppression did not reduce age differences in span, showing that developmental processes other than rehearsal are also important.
