Negative relation between critical flicker fusion frequency and such parameters of visual perception as channel capacity of visual system and visual information processing may seem to be paradoxical because according to the canon of sensor physiology, the higher is the frequency characteristics of the communication channel, the higher its channel capacity [7].
Three separate procedures were conducted to test for treatment effects on visual function: responses to increasing light intensities (V-log I response curves), flicker fusion frequency, and spectral sensitivity.
However, a more recent study (Ostberg, Shahnavaz, & Stenberg, 1987) showed no difference in flicker fusion frequency for the different field scan directions.
Louise Dye consider the menstrual cycle as a biological rhythm and shows that, although cognitive functioning does not show a monthly pattern in women, visual sensitivity (as measured by critical flicker fusion threshold) does.
In the present study, the effect of these two drugs was examined on critical flicker fusion (CFF) which is the one of the most sensitive psychomotor functions test in evaluating cerebral cortical arousal with the objective that outcome of the study would be useful in clinical practice to assess safety of these drugs while handling complex tasks.
plebs eye was quantified using two methods: (1) response waveform dynamics, and (2) flicker fusion frequency.
(2008) reported a progressive increase in critical flicker fusion frequency following 10 day yoga training program.
In these classic studies, he established that the eyes of rapidly moving day-active species have better temporal resolution, as indicated by flicker fusion frequencies of 200-300 Hz, than the eyes of slower moving night-active forms, with flicker fusion frequencies of 10-20 Hz (Autrum, 1950, 1958; Autrum and Stocker, 1952).
The flicker fusion frequency was measured with 10 ms flashes in dark adapted crabs, as well as in crabs adapted to and tested in 11.65 [[micro]watts]/[cm.sup.2] fluorescent light.
