Abstract : The purpose of the study is to investigate the effects of test and inducing field separations upon the foveal critical flicker frequency (c.f.f.), with increasing inducing luminance levels. Emphasis is placed on the determination of: (1) how, and at what inducing luminance levels, the maximal c.f.f. peaks shift; (2) changes in the magnitude of the c.f.f. maxima; (3) the rate at which changes in c.f.f. diminish. An analogy is made between the psychophysical results of the study and the findings of electrophysiological investigations concerning lateral inhibitory interaction within the retina.
