有四项研究报告了记忆广度的发展增长与操作速度或效率的发展增长之间的联系。在第一个，线性关系之间的增加，在字跨度和工作重复的速度增加。在第二，成人和6岁的奥尔兹等同的速度的单词重复，操纵单词熟悉度。在这些条件下，他们的词跨度不再不同。类似的发现，然后报告了一个测试的M空间称为计数跨度。首先，证明了计数跨度的增加与计数速度的增加之间的线性关系。接下来，通过强迫成年人用一种不熟悉的语言数数，成年人和6岁的奥尔兹在数数速度上是相等的。在这些条件下，它们的计数跨度不再不同。记忆广度的发展性增加并不是因为总加工空间的增加。相反，随着开发，基本操作变得更快、更有效，这表明它们需要更少的处理空间，因此有更多的空间可用于存储。
Four studies are reported which link developmental increases in memory span with developmental increases in operational speed or efficiency. In the first, a linear relationship is demonstrated between increases in word span and increases in speed of work repetition. In the second, adults and 6 yr olds are equated on speed of word repetition, by manipulating word familiarity. Their word spans are no longer different under these conditions. Similar findings are then reported for a test of M space called Counting Span. First, a linear relationship is demonstrated between increases in Counting Span and increases in speed of counting. Next, adults and 6 yr olds are equated on speed of counting, by forcing adults to count in an unfamiliar language. Their counting spans are no longer different under these conditions. Developmental increases in memory span do not result from increases in total processing space. Rather, with development, basic operations become faster and more efficient, indicating that they require less processing space, and that more space becomes available for storage as a result.
