Both intensity and frequency discrimination data were collected for the same four subjects using several psychophysical paradigms. No differences were observed that would indicate that frequency discrimination involves fundamentally different decision-making processes than intensity discrimination. In both cases, performance in a two-interval forced-choice task exceeded performance in a yes-no task by a factor greater than the generally predicted 2. Consistent individual differences were observed in frequency discrimination but not in intensity discrimination.
