As people get older, they show a relative preference to remember positive information over negative information. In two experiments, we tested whether the positivity of older adults' memory is affected by stereotype threat about age-related cognitive declines. We also tested whether highlighting a positive aging stereotype (older adults are wise) would inoculate older adults from stereotype threat's adverse effects.
In Experiments 1 and 2, we manipulated whether stereotypes about age-related cognitive decline were highlighted (stereotype threat) or mitigated (stereotype alleviation). In Experiment 2, we included a third condition (intervention + stereotype threat), which highlighted positive and negative aging stereotypes. Participants then saw emotionally evocative pictures and completed a memory test.
In both experiments, stereotype threat selectively reduced older adults' memory for positive pictures but did not affect their memory for negative pictures. This eliminated the positivity effect (i.e., the Age × Valence interaction; Experiment 1). Our positive stereotype intervention did not reduce stereotype threat's adverse effect (Experiment 2).
Our findings show that the positivity effect is more robust when testing situations minimize stereotype threat. They also suggest that health interventions designed to capitalize on the positivity effect should ensure that ageist stereotypes are mitigated in the environment.
随着年龄的增长,人们表现出相对偏好记住积极的信息而不是消极的信息。在两项实验中,我们测试了老年人记忆的积极性是否受到与年龄相关的认知衰退的刻板印象威胁的影响。我们还测试了强调积极的老龄化刻板印象(老年人是明智的)是否能使老年人免受刻板印象威胁的不利影响。
在实验 1 和 2 中,我们操纵了与年龄相关的认知衰退的刻板印象是否突出(刻板印象威胁)或减轻(刻板印象缓解)。在实验 2 中,我们包括了第三个条件(干预+刻板印象威胁),突出了积极和消极的老龄化刻板印象。然后,参与者观看情感唤起的图片并完成记忆测试。
在两项实验中,刻板印象威胁选择性地降低了老年人对积极图片的记忆,但对消极图片的记忆没有影响。这消除了积极性效应(即年龄×效价交互作用;实验 1)。我们的积极刻板印象干预并没有减少刻板印象威胁的不利影响(实验 2)。
我们的发现表明,当测试情境最小化刻板印象威胁时,积极性效应更加稳健。它们还表明,旨在利用积极性效应的健康干预措施应确保在环境中减轻年龄歧视的刻板印象。
