许多研究表明，衰老的特征是中央执行系统的衰退，而自动过程（特别是语音回路的操作）保持不变。根据解释，年龄差异应该是最小的，而他们应该是更重要的，在向后的言语数字广度。1,000名年龄从16岁到79岁的受试者样本被用来检验这一假设。结果表明，年龄对数字广度的前后差异没有显著影响。这些结果的理论意义进行了讨论。
A number of studies has suggested that aging is characterized by a decline in the central executive while the automatic processes (in particular operations by the phonological loop) remain intact. According to interpretation, age differences should be minimal in verbal forward digit span while they should be more important in backward verbal digit span. A sample of 1,000 subjects with ages ranging from 16 years to 79 years was used to test this hypothesis. The results show no significant effect of age on the difference between digit span forward and backward. The theoretical implications of these results are discussed.
