“…A longer viewing distance of 6 m (obtained by viewing using a mirror) was adopted to avoid floor effects, as was seen in younger participants in our pilot work with shorter distances, and as reported previously ( Kuo, Atchison, & Schmid, 2018 ). At 6 m, one pixel subtends a visual angle of 0.2 min of arc, providing a stimulus size of 3° of diameter, similar to that used previously by one of our research groups ( Lacherez, Au, & Wood, 2014 ; Lacherez, Turner, Lester, Burns, & Wood, 2014 ). Participants wore their optimum refraction for the 6-m working distance, using large aperture trial lenses in a trial frame.…”

The perception of motion is considered critical for performing everyday tasks, such as locomotion and driving, and relies on different levels of visual processing. However, it is unclear whether healthy aging differentially affects motion processing at specific levels of processing, or whether performance at central and peripheral spatial eccentricities is altered to the same extent. The aim of this study was to explore the effects of aging on hierarchically different components of motion processing: the minimum displacement of dots to perceive motion (D min ), the minimum contrast and speed to determine the direction of motion, spatial surround suppression of motion, global motion coherence (translational and radial), and biological motion. We measured motion perception in both central vision and at 15° eccentricity, comparing performance in 20 older (60–79 years) and 20 younger (19–34 years) adults. Older adults had significantly elevated thresholds, relative to younger adults, for motion contrast, speed, D min , and biological motion. The differences between younger and older participants were of similar magnitude in central and peripheral vision, except for surround suppression of motion, which was weaker in central vision for the older group, but stronger in the periphery. Our findings demonstrate that the effects of aging are not uniform across all motion tasks. Whereas the performance of some tasks in the periphery can be predicted from the results in central vision, the effects of age on surround suppression of motion shows markedly different characteristics between central and peripheral vision.

“…Older adults have been shown to be less sensitive to changes in vehicle velocities (Scialfa, Guzy, Leibowitz, Garvey, & Tyrrell, 1991) and to have difficulties judging vehicle trajectories (DeLucia & Mather, 2006). In addition, they often fail to identify moving hazards in driving scenes (Lacherez, Turner, Lester, Burns, & Wood, 2014) and miss upcoming collision events (Andersen, Cisneros, Saidpour, & Atchley, 2000;Andersen & Enriquez, 2006;Bian, Guindon, & Andersen, 2013). There is correlational evidence that reduced motion sensitivity might contribute to these difficulties (Conlon et al, 2015;Conlon & Herkes, 2008;Wilkins et al, 2013).…”

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.

“…The normal aging process degrades both auditory and visual temporal perception, contributing to the difficulties older adults encounter with everyday tasks. For example, age-related impairments in speech comprehension and driving performance are associated with temporal processing deficits within audition ( Gordon-Salant and Fitzgibbons, 1993 ; Füllgrabe et al, 2014 ; Babkoff and Fostick, 2017 ) and vision ( Wood, 2002 ; Conlon and Herkes, 2008 ; Lacherez et al, 2014 ), respectively. However, many tasks stimulate both audition and vision.…”

Within each sensory modality, age-related deficits in temporal perception contribute to the difficulties older adults experience when performing everyday tasks. Since perceptual experience is inherently multisensory, older adults also face the added challenge of appropriately integrating or segregating the auditory and visual cues present in our dynamic environment into coherent representations of distinct objects. As such, many studies have investigated how older adults perform when integrating temporal information across audition and vision. This review covers both direct judgments about temporal information (the sound-induced flash illusion, temporal order, perceived synchrony, and temporal rate discrimination) and judgments regarding stimuli containing temporal information (the audiovisual bounce effect and speech perception). Although an age-related increase in integration has been demonstrated on a variety of tasks, research specifically investigating the ability of older adults to integrate temporal auditory and visual cues has produced disparate results. In this short review, we explore what factors could underlie these divergent findings. We conclude that both task-specific differences and age-related sensory loss play a role in the reported disparity in age-related effects on the integration of auditory and visual temporal information.
