Research on functional changes across the adult lifespan has been dominated by studies related to cognitive processes. However, it has become evident that a more comprehensive approach to behavioral aging is needed. In particular, our understanding of age-related perceptual changes is limited. Visual motion perception is one of the most studied areas in perceptual aging and therefore, provides an excellent domain on the basis of which we can investigate the complexity of the aging process. We review the existing literature on how aging affects motion perception, including different processing stages, and consider links to cognitive and motor changes. We address the heterogeneity of results and emphasize the role of individual differences. Findings on age-related changes in motion perception ultimately illustrate the complexity of functional dynamics that can contribute to decline as well as stability during healthy aging. We thus propose that motion perception offers a conceptual framework for perceptual aging, encouraging a deliberate consideration of functional limits and resources emerging across the lifespan.
关于成年期全生命周期功能变化的研究一直以与认知过程相关的研究为主导。然而，显然需要一种更全面的行为衰老研究方法。特别是，我们对与年龄相关的感知变化的理解是有限的。视觉运动感知是感知衰老研究最多的领域之一，因此，它提供了一个很好的领域，在此基础上我们可以研究衰老过程的复杂性。我们回顾了关于衰老如何影响运动感知的现有文献，包括不同的处理阶段，并考虑了与认知和运动变化的联系。我们探讨了结果的异质性，并强调个体差异的作用。关于运动感知中与年龄相关变化的研究结果最终说明了功能动态的复杂性，这种复杂性可能导致健康衰老过程中的衰退以及稳定性。因此，我们提出运动感知为感知衰老提供了一个概念框架，鼓励人们慎重考虑一生中出现的功能限制和资源。
