人们通常认为，尽管在正常衰老过程中外显学习有所下降，但内隐学习却相对保留。在这里，我们总结了我们小组的研究，这些研究使我们认为某些形式的内隐学习确实会随着成年年龄的增长而下降。特别是，我们提出，在整个成年人的一生中，概率顺序关系的内隐学习会出现与年龄相关的下降，并且它们至少部分反映了与年龄相关的纹状体功能障碍。我们首先回顾支持这种与年龄相关的衰退的行为证据，然后回顾支持这种纹状体功能障碍假说的患者群体、遗传学和神经影像学证据。
It is often held that although explicit learning declines in the course of normal aging, implicit learning is relatively preserved. Here we summarize research from our group which leads us to argue that some forms of implicit learning do decline with adult age. In particular, we propose that there are age-related declines in implicit learning of probabilistic sequential relationships that occur across the adult lifespan, and that they reflect, at least in part, age-related striatal dysfunction. We first review behavioral evidence supporting this age-related decline and then evidence from patient groups, genetics, and neuroimaging supporting this striatal dysfunction hypothesis.
