Flicker Fusion Thresholds and Mental Arousal
Perceptual and Motor Skills, 1982 Investigated the finding of Busch and Wachholder that flicker fusion thresholds increase under conditions of mental activity and decrease during inactivity. Flicker fusion thresholds for each eye of 21 undergraduates were measured after 2-min. rests, then after the performance of a mathematical counting exercise, and then after another 2-min. rest. The

Flicker fusion thresholds in pregnancy
American Journal of Obstetrics and Gynecology, 1952Abstract 1. 1. A brief review of pertinent physiology in flicker phenomena is presented. 2. 2. The results of a study of 118 gravid women and 465 flicker fusion tests are presented and analyzed. 3. 3. A false-positive result is noted in 14 per cent and a false-negative in 3.3 per cent. 4. 4.

Phase Relations in Flicker Fusion
Journal of the Optical Society of America, 1962The luminance at which the flicker of a white test light was perceived was determined as a function of the phase angle between the light and pulsing white, green, yellow, red, and blue surround fields which were equated for brightness. It was found that the luminance thresholds for perceived flicker increased when the test light and the surround were ...

Science, 1959
Brown and Forsyth have recently performed a flicker-fusion experiment showing clearly that there is more to flicker than meets the eye. This report presents an analysis of their results which indicates the likelihood that at fusion threshold all but one of the Fourier components of their presentation are imperceptible.

Flicker waveform has been found to have a slight but specific effect upon fusion threshold. A depression of threshold amplitude of about 30 percent occurs if a second harmonic of near-threshold amplitude is added to the fundamental. The magnitude of the depression depends critically on the relative phase of the two components of the waveform.

The author reviews several phenomena occurring in sine wave flicker experiments, classifying them into low-frequency (below 10 cps) and highfrequency (above 20 cps) effects, and suggests that two different, kinds of mechanisms are needed to account for the behavior of amplitude sensitivity curves in these two frequency ranges.

The high-frequency temporal behavior of the human visual system has been shown to have some of the properties of a linear low-pass filter. For such a system it is appropriate to consider a repetitive stimulus as having separable Fourier harmonic components.
