Critical Flicker Frequency and Intelligence*
Tests of verbal intellegence (Concept Mastery Test) and nonverbal intelligence (Raven's Advanced Progressive Matrices) showed nonsignificant zero-order correlations and a nonsignificant multiple correlation with critical flicker frequency (CFF), in 100 university students. Age-partialled correlations were even lower, and corrections for attenuation and restriction of range yielded unimpressive ...
متن کاملInfluence of flicker frequency on flicker-induced changes of retinal vessel diameter.
PURPOSE To investigate the effect of diffuse luminance flicker of different frequencies on retinal vessel diameter in the human eye. METHODS Nine healthy subjects participated in the study. A retinal vessel analyzer (RVA; Zeiss, Jena, Germany) was modified to allow for continuous measurement of vessel diameter during flicker stimulation. With this technique, the light used for measurement of ...
متن کاملIntensity 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 flicker frequency and centrally-acting drugs.
THE critical flicker frequency (cff) may be defined as the fastest rate at which a flickering source of light appears to be flickering as opposed to being steady. It has a number of determinants including the luminance, wave-length, wave-form, and light-dark ratio of the stimulating light, the area, position, and light-adapted state of the retina illuminated, the duration of exposure, and the s...
متن کاملFlicker fusion frequency in amblyopia ex anopsia.
Amblyopia ex anopsia is characterized by a defect in visual acuity of one eye, beginning in infancy, often with strabismus. The amblyopia disappears upon occlusion of the dominant eye in children, but not readily in adults. Peripheral acuity and sensation remain normal in field and threshold studies. It is believed that the origin of the amblyopia is in the macular projection of the visual cort...
