The Response of the Flicker Fusion Threshold
Flicker fusion threshold (F.F.T.) means the frequency with which successive flashes of light must occur to just appear to the eye free from flicker. A simple portable machine is described which will deliver flashes of light at any required interval. Patients with hypertension or anemia have a lower than normal F.F.T.; furthermore, administration of nitroglycerin, 0.4 mg. sublingually, or papave...
متن کاملTwo Visual Training Paradigms Associated with Enhanced Critical Flicker Fusion Threshold
Critical flicker fusion thresholds (CFFTs) describe when quick amplitude modulations of a light source become undetectable as the frequency of the modulation increases and are thought to underlie a number of visual processing skills, including reading. Here, we compare the impact of two vision-training approaches, one involving contrast sensitivity training and the other directional dot-motion ...
متن کاملFlicker noise near the percolation threshold
2014 An effective-medium theory, for the flicker (1/f) noise amplitude, is formulated for random resistor networks. Close to the percolation threshold pc, the magnitude of the noise is shown to diverge as (p pc)-03BA, with 03BA = 1 for both site and bond percolation models. The exponent 03BA is also calculated in the framework of two different renormalization group transformations. The possible...
متن کاملFlash Expansion Threshold in Whirligig Swarms
In the selfish herd hypothesis, prey animals move toward each other to avoid the likelihood of being selected by a predator. However, many grouped animals move away from each other the moment before a predator attacks. Very little is known about this phenomenon, called flash expansion, such as whether it is triggered by one individual or a threshold and how information is transferred between gr...
متن کاملThe effect of hypoxia on the critical flicker fusion threshold in pilots.
OBJECTIVES Human reactions to environmental changes have been the subject of numerous investigations related to pathophysiology, aviation psychology, aviation, and sports. The present study aimed at evaluating the perception of light stimulus via the Critical Flicker Fusion threshold (CFF) measurements among aviation pilots. MATERIALS AND METHODS The study was carried out under hypoxic condit...
