“…In the current study, linear regression analysis in controls showed a decrease of CFF by 0.66 Hz per life decade and a decrease by 1.25 Hz per life decade in cirrhotic patients without MHE. This observation is in accordance with those observed in previous studies [35,36]. The concept that aging influences the functions of specialized visual system is further supported by the data that showed significant delay in the latencies of the first major negative and of the first major positive deflection of the visual evoked responses with advancing age [37].…”

“…The concept that aging influences the functions of specialized visual system is further supported by the data that showed significant delay in the latencies of the first major negative and of the first major positive deflection of the visual evoked responses with advancing age [37]. Aging causes morphologic changes in the optics of the eye and the cellular elements of the retina and the afferent visual system [35,[38][39][40]. The cause of the decrease of CFF may lie in peripheral factors (optics of the eye or the retina) or central factors (optic nerves or optic pathways or both).…”

“…It has been reported, not only in vision, although the preponderance of the literature concerns that modality, but also in hearing and touch (Coltheart, 1980). Visual persistence lasts longer in older subjects (Amberson, Atkeson, Pollack, & Malatesta, 1979;Brozek & Keys, 1945;Kline & Birren, 1975;Kline & Szafran, 1975;McFarland, Warren, & Karis, 1958;Misiack, 1951). Mundy-Castle (1953) found that the EEG response to photic stimuli is prolonged as age increases.…”

The psychophysical responses to vibration of two age groups (22 or 25 and 66 years) were compared for two tasks using suprathreshold levels of vibrotactile stimulation. At a vibration frequency of 25 Hz, the two age groups gave similar curves of subjective magnitude determined by the method of absolute magnitude estimation. At 250 Hz, the curve of the older group showed no recruitment over low levels of intensity. Instead, their magnitude estimates were depressed over the entire range of intensities. Sensory persistence, measured by a matching procedure, was more marked in the older group.The effect of aging upon the absolute detection threshold for vibration has been reported in a number of publications (

“…This study also indicates that, by puberty, intelligence may begin to playa role, and that CFF should begin to decline beyond the age of 12 as the cognitive function of taking into account traces of stimuli interferes with perception of the dark interval. A study by Misiak (1951) also lends support to these notions. There was a nonsignificant increase in CFF between his 7-11 and 12-16 year-old groups.…”

The dark-interval threshold as a function of age

1968

The threshold for the dark interval between two flaslles was illl'estigated ill 100 elementary school children, age 6-IU. It was foulld that Ille threshold decreased with chrollological age, 'a findillg altribllted to physiological agillg of Ille I'isual receptor system producillg diminished persistence of tile illitial stimulus.Pollack (\ 968) has put forth a two-process theory to ex plain age changrs in visual perception_ One of these processes. nondevelopmental in nature. involves a progressive loss in receptor sensitivity due to physiological aging_ The other process is "developmental" in that age changes are related to central cognitive functions and abilities which are hierarchically organized. Within the framework of this theory, those phenomena which show non developmental age changes (Type I) are not correlated with intellectual ability. but appear to be related directly to receptor efficiency and various stimulus variables such as intensity, duration, contrast, and orientation. Those phenomena showing developmental age changes (Type II) are correlated with intellectual ability and do not depend as much upon classical stimulus variation. Presentation of such phenomena usually involves a sequence of discrete stimulus events, registered by the S as traces, which are then centrally compared and contrasted.It is assumed that in making judgments about two stimuli presented in rapid succession, the individual early in life makes use of the physical persistence of the initial stimulus to make what is virtually a simultaneous comparison. As this stimulus persistence weakens as a function of aging in the receptor system, comparison comes to be based upon the higher-order cognitive function of comparing the trace of the vanished initial stimulus ...,ith the second stimulus. This transition was demonstrated by Pollack (1966) in a study dealing with apparent movement. The temporal range of apparent movement decreased between the ages of 6 and 9, but increased again beyond the age of 9. Correlation with IQ was nonsignificant for the 6-to 9-year-olds, but positive and significant for the 10-and Il-year-olds. The pattern of results obtained in this experiment was very similar to that obtained in an earlier study by Pollack (1960), concerning the frequency of occurrence of figural aftereffects following brief inspection.The present experiment was designed to test further the hypothesis that stimulus persistence declines with age. The dark-interval threshold (Din can be thought of as a simplified version of the critical flicker frequency (CFF), in which two flashes of light are presented in quick temporal succession with a varying interflash interval. The S is simply asked to report whether he can detect a dark interval between the flashes. At the present time, data on the DIT are very scarce. In general, results from studies of CFF have shown a decrease in CFF (poorer performance) beyond the age of 14. Cross (1963) performed a study of CFF with an age range of 6 to 12 years. She found a significant increase in CFF (bet...
