之前的研究表明，言语记忆广度，即人们能够记住并立即重复的单词的数量，与他们发音的最快速度有关。这种关系反过来又被归因于信息处理的总体或全球速度，这种速度因个体而异，并随年龄而变化。然而，本文所描述的实验表明，快速发音和从短时记忆中提取单词这两个加工的速度与记忆广度有关，但彼此之间不相关。记忆广度取决于大脑中的处理速度，而不仅仅是整体速度。此外，随着年龄变化的比率变量与个体不同的比率变量之间似乎只有部分重叠。
Previous research indicates that verbal memory span, the number of words people can remember and immediately repeat, is related to the fastest rate at which they can pronounce the words. This relation, in turn, has been attributed to a general or global rate of information processing that differs among individuals and changes with age. However, the experiments described in this article showed that the rates of 2 processes (rapid articulation and the retrieval of words from short-term memory) are related to memory span but not to each other. Memory span depends on a profile of processing rates in the brain, not only a global rate. Moreover, there appears to be only a partial overlap between the rate variables that change with age and those that differ among individuals.
