Overshoot effect for short tones played soon after a noise masker. (A) Schematic shows the stimulus configuration. The duration of the noise masker was held constant at 200 ms, whereas the duration of a 4 kHz or 16kHz tone was either 6.5 ms (as shown) or 12.5 ms. Two exemplar psychometric functions from monkey E shows the horizontal dynamic range shift as a result of noise with 0 ms onset asynchrony (the onsets of noise and tone overlapped) and a negative asynchrony of 50 ms (the signal onset was delayed by 50 ms after the noise onset). (B) Tone detection thresholds are plotted as a function of the onset asynchrony for monkey D (red) and monkey E (gray). The amplitude of the noise used was either 10 (monkey D) or 30 (monkey E) SPL. Threshold functions are shown for 6.5 ms signals (open symbols) and 12.5 ms signals (filled).
