Intensity and Critical Frequency for Visual Flicker
Using the rotating striped cylinder device previously employed for determination of the flicker response function with lower animals, corresponding measurements have been made with human observers. The curves based upon the relation between critical flash frequency and critical intensity for the signalling of the recognition of flicker have the properties of human flicker fusion data as obtaine...
متن کاملCritical Intensity and Flash Duration for Response to Flicker: with Anax Larvae
Determinations of the flicker response curve (F - log I(m)) with larvae of Anax junius (dragonfly) for various ratios t(L)/t(D) of light time to dark time in a flash cycle provide relations between t(L)/t(D) and the parameters of the probability integral fundamentally describing the F - log I function, including the variability of I. These relations are quantitatively of the same form as those ...
متن کاملViagra slows the visual response to flicker
As an undesirable side effect, sildenafil citrate (Viagra) partially inhibits the phosphodiesterase PDE6 [1], which plays an essential role in phototransduction (reviewed in [2,3]). PDE6 not only activates the visual transduction cascade, but also controls the time over which the visual response is integrated, thereby helping to maintain the size of the visual response within an optimal range a...
متن کاملthe differential effects of debate and media analysis as relate to enhancing efl learners critical thinking ability and writing performances
critical thinking ability has an important role in education. accordingly, scholars around the world are searching for new ways for teaching and improving students critical thinking ability. in line with the studies in efl contexts supporting the positive relationship between critical thinking and writing performances, this study investigated the differential effects of halverson’s critical thi...
15 صفحه اولOn the Variability of Critical Illumination for Flicker Fusion and Intensity Discrimination
From the data of experiments with bees in which threshold response is employed as a means of recognizing visual discrimination between stripes of equal width alternately illuminated by intensities I(1) and I(2), it is shown that the detectable increment of intensity DeltaI, where DeltaI = I(2) - I(1), is directly proportional to sigma(I2) (I(1) being fixed). From tests of visual acuity, where I...
