Pure-tone Weber functions slope downward across all tested frequencies

Evidence

Jesteadt et al.’s data look rather different from those of Miller, as the functions for pure tones are not horizontal lines, but rather they have negative slopes. Jesteadt et al. actually measured seven different tone frequencies, with the same results for all frequencies. From their data, along with those of Reisz, we conclude that: • Weber’s law did not hold for tones. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 822
