先前的研究在比较大学生年龄段和老年人时，已经证明了在高阶序列的内隐学习方面存在与年龄相关的缺陷（例如，J. H. 霍华德和D. V. 霍华德，1997）。本研究考察了这些年龄缺陷是否始于中年。结果显示，与“较年轻”的中年人相比，“较年长”的中年人在模式敏感性方面存在可靠的与年龄相关的缺陷，并且通过速度和准确性两种测量方法，年龄都能可靠地预测对序列的敏感性。这些结果与T. A. 萨尔托斯（1996）认知老化的同时性机制所反映的一般性认知资源的年龄相关衰退是一致的。
Previous studies have demonstrated age-related deficits in implicit learning of higher order sequences in comparisons of college-age and elderly adults (e.g., J. H, Howard & D. V. Howard, 1997). This study examined whether these age deficits begin in middle age. Results showed a reliable age-related deficit in pattern sensitivity in "older" compared with "younger" middle-aged people, and age reliably predicted sensitivity to the sequence by using both speed and accuracy measures. The results are consistent with an age-related decline in a generic cognitive resource as reflected in T. A. Salthouse's (1996) simultaneity mechanism of cognitive aging.
