The mere-exposure effect, in which repeated stimuli are liked more than novel stimuli, is a well-known effect. However, little research has studied adult age differences in mere-exposure effects, despite possible applications in helping older adults transition to new living environments. Here, we report four experiments assessing mere-exposure to neutral-face stimuli in groups of older and younger adult participants tested online. In each experiment, repeated face exposure did not increase liking within either age group; rather, Bayesian evidence favored the null hypothesis of no effect. Older adults reported higher overall liking ratings relative to younger adults, and both groups preferred younger faces, though this tendency was stronger in the younger group. Further exploratory analysis considering factors such as gender or race of the faces and participants did not reveal any consistent results for the mere-exposure effect. We discuss these findings in relation to other recent studies reporting mixed evidence for mere-exposure effects. (PsycInfo Database Record (c) 2022 APA, all rights reserved).
单纯曝光效应是指重复出现的刺激比新颖的刺激更受欢迎，这是一种众所周知的效应。然而，尽管单纯曝光效应在帮助老年人适应新的生活环境方面可能有应用，但很少有研究探讨成人年龄差异对单纯曝光效应的影响。在这里，我们报告了四项实验，评估了在在线测试的老年和年轻成年参与者群体中对中性面孔刺激的单纯曝光。在每项实验中，重复的面孔暴露并没有增加两个年龄组的喜好程度；相反，贝叶斯证据支持没有影响的零假设。与年轻成年人相比，老年人的总体喜好程度更高，并且两个群体都更喜欢年轻的面孔，尽管这种趋势在年轻群体中更强。进一步考虑面孔和参与者的性别或种族等因素的探索性分析，并没有为单纯曝光效应提供任何一致的结果。我们将这些发现与其他最近报告单纯曝光效应证据不一的研究联系起来进行讨论。（PsycInfo 数据库记录（c）2022 APA，保留所有权利）。
