The 3-down one-up adaptive rule tracks 79.4 percent correct thresholds
Evidence
Thresholds were estimated using an adaptive psychophysical procedure employing 60 trials. The signal contrast level was reduced after three consecutive correct responses and increased after a single incorrect response. Initially the contrast was varied in a step size of 2 dB, which was reduced to 0.5 dB after three reversals in the adaptive track (Levitt 1971 ). — Dijk, Pim van, Physiology, Psychoacoustics and…, 1847
