Drug Medical Information
AGE AND BEHAVIOR: PROCESSING SENSE INFORMATION - SEQUENTIAL INTEGRATION - CLICK FUSION
CFF thresholds are measures of the perceptual fusing of discrete visual stimuli. The young perceive these inputs as discrete more readily than do the aged—their perceptions are more in keeping with objective reality. An auditory analogue of this visual fusion was seen in studies utilizing sound clicks (Weiss and Birren, reported by Weiss, 1959; and Weiss, 1963). Two sound clicks were presented in rapid order to both ears of a subject, who tried to determine whether it sounded to him as two clicks or a fused one click. The difference between a young age group and an over-65-year age group was not great, but tended to a pattern similar to that of CFF: Fusion of the two clicks came about more readily for the old. Again, the young perceived objective reality better than did the old. The subjects also were given a train of clicks, 1 to 10 in number, and these were varied in the rate of delivery. "On the whole, older subjects reported significantly fewer clicks than younger subjects" (Weiss, 1959). It was as if the persistence of the stimulus trace of the earlier part of the train of clicks fused with later parts to make differentiation more difficult. Weiss (1963) later compared young men to each of two groups of men over 65 years, differing in their states of health. One group of the older men was what is typically called "normal" healthy and the other group was of men of extraordinary health—no sign of disease whatsoever. The comparisons were of the time between clicks in which fusion was perceived. The young and extraordinary elderly groups were not different from each other, but the young and "normal" healthy groups were different in accord with the stimulus persistence model: The old perceived fusion with more time between clicks. Perhaps it is the combination of age and ill health that makes for stimulus persistence. *183\220\8*
