The Effect of Session Replication and the Duration of the Interval Between Sessions on Critical Flicker Frequency
Abstract
Critical flicker frequency (c.f.f.) may be defined as that frequency above which a pulsating light source is first experienced as a continuous stimulus of uniform brightness. Of the numerous c.f.f. experiments which appear in the literature, many of them being identified in the annotated bibliography compiled by Landis (9), most may be classified into one of two categories. There are those concerned with the application of c.f.f. as a criterion or a measure of: visual fatigue, drug affects, and so on. Then there are those experiments conducted to determine the important variables affecting c.f.f. such as stimulus intensity, wavelengths, and so on.Of these latter variables, one which has received considerable attention is the effect of repeated measurements on the same subjects. Because such factors as fatigue, motivation, attention, learning, etc. Interestingly operate within the subject for any given session, a subject' s c.f.f. threshold may significantly change from session to session. In investigating this problem, however, conflicting evidence has been found.
