Forward masking and gap detection measure the same resolution differently

Evidence

The results from Hawkins and Stevens (1950) illustrate a small, but robust, effect of signal frequency. However, we can better observe the relationship between the frequency of maskers and the frequencies of the signals when experiments are conducted under variable frequency conditions. — Jennifer Lentz, Psychoacoustics- Perception of Normal…, 461 (#expands, via linked claim)

For each participant, several suppressor levels were presented, and the level producing the greatest amount of suppression was used for analysis. The suppressor was an average of 4 dB below the off-frequency masker threshold obtained in Experiment 1 [SD = 1.60]. For younger adults, suppressors were presented at an average of 74.50 dB SPL [SD = 5.22] for low-side suppression and 74.23 dB SPL [SD = 4.00] for high-side suppression. For older adults, suppressors were presented at an average of 67.60 dB SPL [SD = 2.12] for low-side suppression and 75.20 dB SPL [SD = 3.68] for high-side suppression. — Dijk, Pim van, Physiology, Psychoacoustics and…, 940 (#qualifies, via linked claim)

  • XREF: connects to: Forward masking persists up to 200 ms after the masker ends; Forward masking avoids the nonlinear effects that only arise from simultaneity.; Temporal ordering thresholds exceed gap detection thresholds by requiring memory (+3 more)
