在有意编码和提取条件下，存在与年龄相关的联想加工障碍的强有力证据，但附带联想加工的状况尚不清楚。在两个实验中，我们研究了年龄对快速反应学习的影响，即附带学习的刺激反应联想，当学习的反应变得不适合新任务时，它会导致启动减少。实验1表明，在两个年龄组中，任务特定决策线索的反转对启动的敏感性相同。外分类任务和实验2中的线索倒置消除了对该任务的联想版本的启动，因此，在老化过程中似乎保留了编码刺激及其初始任务特异性反应之间的关联的能力。提供了一个重要的例子，说明老年人的联想处理形式没有受到损害，
Strong evidence exists for an age related impairment in associative processing under intentional encoding and retrieval conditions but the status of incidental associative processing has been less clear In 2 experiments we examined the effects of age on rapid response learning the incidentally learned stimulus response association that results in a reduction in priming when a learned response becomes inappropriate for a new task Specifically we tested whether priming was equivalently sensitive in both age groups to reversal of the task specific decision cue Experiment 1 showed that cue inversion reduced priming in both age groups with a speeded inside/outside classification task and in Experiment 2 cue inversion eliminated priming on an associative version of this task Thus the ability to encode an association between a stimulus and its initial task specific response appears to be preserved in aging These findings provide an important example of a form of associative processing that is unimpaired in older adults
