Hyper-binding refers to the spontaneous formation of target-distractor associations in older adults, with consequences for subsequent memory. While hyper-binding reflects a loss of attentional and mnemonic selectivity in aging, a growing literature suggests that motivational states modulate cognitive performance in both younger and older adults. In the current study, healthy younger and older adults (N = 48 in both age groups) completed a face-name hyper-binding task with or without motivational incentives during incidental encoding. Results revealed a motivation-related decrease in hyper-binding in older adults, leading to a paradoxical motivation-related memory decrement in this age group. These findings suggest that reward motivation can counteract age-related deficits in inhibition and attentional selectivity, without necessarily boosting memory performance.

动机对老年人面部表情过度约束的影响。

过度结合是指老年人中靶标-干扰物协会的自发形成，对随后的记忆产生影响。虽然过度约束反映了衰老过程中注意力和记忆选择的丧失，但越来越多的文献表明，动机状态会调节年轻人和老年人的认知能力。在当前的研究中，健康的年轻人和老年人（两个年龄组均为N = 48）在偶然编码过程中完成了带有或不带有激励措施的面部表情超绑定任务。结果显示，老年人中与动机相关的过度约束力降低，导致该年龄组与动机相关的记忆减少。这些发现表明，奖励动机可以抵消与年龄相关的抑制和注意力选择性缺陷，而不必提高内存性能。（PsycInfo数据库记录（c）2020 APA，保留所有权利）。
