视觉敏感度随着年龄的增长而下降，这可能会影响面部识别。然而，在基本的视觉处理和在介导面部识别的感觉和认知机制的老化之间的关系还没有得到很好的理解。人脸检测是人脸识别的基础步骤，主要依赖于感官信息。这项研究测量了年轻人（<40岁）、中年人（40-59岁）和老年人（>59岁）检测面部结构和对比度检测的能力。与年轻组相比，中年组的人脸检测和对比度检测性能中度下降，老年人的性能进一步下降。人脸检测与对比敏感度有很强的相关性，但与语言智商的相关性很弱。结果表明，人脸检测能力在衰老早期开始下降，并与时空视觉加工有关。
Visual sensitivity decreases with age, and this presumably has an impact on face recognition. However, the relationship between aging in basic visual processing and in the sensory and cognitive mechanisms mediating face recognition is not well understood. Face detection, a foundational step in recognizing faces, relies primarily on sensory information. This study measured the ability to detect facial configuration and contrast detection in young (<40 years), middle–aged (40–59 years), and elderly adults (>59 years). Performance on both face detection and contrast detection was moderately degraded in the middle-aged group compared with the young group and was further degraded in elderly adults. Face detection was correlated strongly with contrast sensitivities, but only weakly with verbal IQ. The results suggest that face detection ability begins to reduce in early aging, and is associated with spatiotemporal visual processing.
