Abstract
CFF thresholds were obtained from 3 observers at each of 5 frequencies, 5 areas and 4 wavelengths of the stimulus, and the slopes of the log I-log A curves computed. The significance of the wavelength effect and of the interaction effect of frequency and wavelength upon these slopes indicates that wavelength is a determinant of the CFF threshold. The slopes for the red and blue stimuli were greater than those for the yellow and green at the higher frequencies.Keywords
