Temporal factors in visual perception as related to aging

Age-dependent magnitude and time course of early light adaptation

“…The subject with the anomalous results was 47 years old, whereas all the others were in their 20s. Since there is a growing body of evidence documenting losses in temporal response properties of the aging visual system (Eriksen, Hamlin, & Breitmeyer, 1970;Kline & Orme-Rogers, 1978;Kline & Schieber, 1981;Pollack, 1978;Walsh, 1976), we postulated that the ELA function would also manifest age-dependent changes. This report describes a study designed to test this hypothesis.…”

Age-related changes in visual lobe shape characteristics and their relationship to visual search performance

“…Many researchers investigated visual lobe size and measured its dimensions on the horizontal and vertical axes (Bellamy and Courtney 1981; (Lesch et al 2011) and have a longer processing time for visual information (Eriksen, Hamlin, and Breitmeyer 1970;Scialfa and Joffe 1997). As a result, as age increases, visual search performance deteriorats significantly (Allen et al 1992;Andersen et al 2010;Batsakes and Fisk 2000;Busey et al 2010), particularly when the target has no salient features that are different from distracting stimuli (Madden, Gottlob, and Allen 1999).…”

Visual Masking: A Reliable Measure for the Assessment of Cognitive Dysfunction in the Elderly?

“…Critical target duration for the perception of the unmasked letters was first determined for each subject. Criterion was 80% (20 out of 24) correct answers (Eriksen et al, 1970). The initial target duration of 10 ms was increased in steps of 5 ms until the criterion was reached.…”

“…In fact, using psychophysical methodologies such as visual masking or visible persistence (for reviews see Breitmeyer, 1984;Di Lollo, Arnett, & Kruk, 1982), consistent age-related differences in the rate of visual information processing have been found (Coyne, 1981;Cramer, Kietzmann, & van Laer, 1982;Di Lollo et al, 1982;Eriksen, Hamlin, & Breitmeyer, 1970;Till & Franklin, 1981;Walsh, Till, & Williams, 1978). In addition, large differences in performance in visual masking tasks have also been reported between healthy elderly subjects and patients with various degrees of Alzheimer's disease (Coyne, Liss, & Geckler, 1984;Schlotterer, Moscovitch, & Crapper-McLachlan, 1983).…”
