“…We found that as spatial frequency increased from .4 cycle per degree of visual angle (c/d), persistence also increased (our results have been replicated by Bowling, Lovegrove, & Mapperson, 1979). Similarly, persistence increases if the target is a single bar of decreasing width (Meyer & Maguire, 1979). These results are consistent with results showing that reaction time increases with increasing spatial frequency (Breitmeyer, 1975;Vassilev & Mitov, 1976) and that critical duration (ontime-luminance reciprocity at threshold) likewise increases with increasing spatial frequency (Breitmeyer & Ganz, 1977;Legge, 1978).…”

Two experiments investigated the properties of visual persistence as functions of spatial frequency, stimulus duration, and pattern-specific adaptation. In Experiment 1, increasing the duration of high spatial-frequency gratings from 50 to 500 msec decreased the duration of visual persistence produced by that grating to an asymptotic level. However, low-frequency gratings produced a constant estimate of visual persistence independent of presentation time. Also, spatial-frequency specific adaptation reduced the persistence of the high-frequency gratings to this asymptotic level, but the lower frequency persistence estimates already at this level were unaffected (Experiment 2). These findings are related to possible temporal properties of the sustained and transient visual systems.

“…Visual persistence has been shown to be sensitive to spatial-frequency specific adaptation Meyer & Maguire, 1979). The effect of such adaptation is to shorten the persistence of the target grating relative to appropriate controls.…”

“…In the present experiment, this would mean that the accelerating frame sequence increased the subjects' attention to the words, which led , in turn, to increases in perceived duration and memory. This explanation complements Meyer and Maguire's (1979) finding that the visual persistence of sine-wave gratings increases as a function of spatial frequency. The present results suggest that visual persistence is positively related to temporal frequency as well.…”

This experiment explored the relationship between perceived time and memory. One hundred and forty-four subjects viewed a list of 30 words under one of three conditions. The conditions were designed to induce differences in the perceived duration of the words by varying the number of incidental stimuli during the period just before each word was visible. After viewing the list, all subjects estimated the duration of each word, the number of words, and the duration of the list. Following this, subjects attempted to recognize the words among 50 distractors. It was found that increases in memory accompanied increases in perceived duration. The results were consistent with the hypothesis that changes in time perception and memory are mediated by changes in attention.

“…Over the range of spatial frequencies tested, no change in visual persistence was noted for sine-or square-wave stimuli for either subject. This is not surprising, since in previous studies it has been reported that large increases in persistence usually occur at higher spatial frequencies (Badcock & Lovegrove, 1981;Meyer & Maguire, 1979). More importantly, no difference in persistence between sine-and square-wave stimuli was noted at any spatial frequency for either subject.…”

“…This is understandable, since the third harmonic component is the most visible spatial component in this waveform. Increased persistence with spatial components above 7.5 cpd (the third harmonic of the 2.5-cpd missing fundamental waveform) is well documented (Badcock & Lovegrove, 1981;Meyer & Maguire, 1979).…”
