轻度精神发育迟滞的儿童进行了比较，CA匹配和言语年龄匹配的儿童没有精神发育迟滞的向前数字跨度任务。前向数字跨度通常被用作语音回路的测量（Baddeley，1986）。我们假设，智力相关的差异，向前数字广度在很大程度上是由于中央执行功能，而不是语音回路功能。结果表明，当中央执行功能的测量是协变时，非常显着的组间差异，向前数字广度减少到不显着。
Children with mild mental retardation were compared with CA-matched and verbal-age-matched children without mental retardation on a forward digit span task. Forward digit span is typically used as a measure of the phonological loop (Baddeley, 1986). We hypothesized that intelligence-related differences in forward digit span are largely due to central executive functioning rather than phonological loop functioning. Results showed that the highly significant group difference in forward digit span was reduced to nonsignificance when a measure of central executive functioning was covaried out.
