Assessment of Psychophysical Methods for Measuring the Critical Flicker Fusion Frequency in Yes/No Tasks

The Critical Flicker Fusion (CFF) threshold is widely used to evaluate the limits of visual temporal processing and has important practical applications in the field of display technologies. In this study, we evaluate the suitability of a novel adaptive psychophysical procedure for measuring CFF thresholds in a YES/NO task. Our results indicate that while the adaptive staircase procedure has high repeatability and is of shorter
duration when compared to the more robust constant stimuli method, its accuracy is lower, giving thresholds that were significantly higher (p<0.01) by approximately 15Hz.
