Abstract

Two experiments utilizing different psychophysical methods provided comparable estimates of the discriminability of differences in the rate of flashing of an alerting signal. In Exp. 1, a contingent-uncertainty analysis resulted in an estimated Weber ratio of < 0.07. In Exp. 2, the method of constant stimuli produced a mean Weber ratio of 0.06. Discriminability of flash rate differences was comparable for red and amber targets and for targets of ∼ 1° and 5° of visual angle.
