Demographic trends indicate an increasing elderly population accompanied by an increase in the prevalence of individuals with Alzheimer's disease (AD). These trends are likely to result in increasing numbers of elderly individuals who wander away from home or care facilities. There is limited research on the efficacy of systems for alerting the public about missing elderly individuals, such as Silver Alerts (SA). Previous research on SAs was limited to alerts featuring White senior citizens. The present study is the first to extend SA research to Black senior citizens. A sample of college students ( = 210) viewed a mock SA along with a short video of a "missing" couple and later attempted to recognize the two individuals from a series of photos. The male and female targets were shown in the SA either together or separately and with or without glasses, and participants were shown photos with and without glasses. The results indicated no effect of whether the couple was shown together or separately, but participants were more likely to recognize the missing male without glasses when he had been shown without glasses in the SA. The female target was recognized more often when wearing glasses than when not wearing glasses, irrespective of how she had been shown in the SA. The results suggest that the appearance of the target at encoding and at recognition may affect ability to identify the target, but that such effects may depend on individual characteristics.

人口趋势表明老年人口在增加，同时阿尔茨海默病（AD）患者的患病率也在上升。这些趋势可能导致离家出走或从护理机构走失的老年人数量增加。关于向公众通报失踪老年人的系统（如银色警报[SA]）的有效性的研究有限。先前关于银色警报的研究仅限于以白人老年人为特征的警报。本研究首次将银色警报研究扩展到黑人老年人。一组大学生（n = 210）观看了一个模拟银色警报以及一段“失踪”夫妇的短视频，随后试图从一系列照片中认出这两个人。男性和女性目标在银色警报中要么一起出现，要么分开出现，并且戴着或不戴眼镜，而给参与者展示的照片也有戴眼镜和不戴眼镜的情况。结果表明，这对夫妇是一起展示还是分开展示没有影响，但当失踪男性在银色警报中未戴眼镜展示时，参与者更有可能认出不戴眼镜的他。无论女性目标在银色警报中是如何展示的，当她戴眼镜时比不戴眼镜时被认出的次数更多。结果表明，目标在编码和识别时的外貌可能会影响识别目标的能力，但这种影响可能取决于个体特征。
