Behavioral decision weights track cochlear fine-structure depth independent of spontaneous emissions

Evidence

The correlation between the relative decision weight and the level difference between tones near fine-structure maxima and tones near minima is statistically significant (r2 = 0.48, p = 0.000014). This outcome suggests that the association between decision weights and OAEs does not depend on detection of SOAEs. — Dijk, Pim van, Physiology, Psychoacoustics and…, 5786

• XREF: Connects to the broader literature linking otoacoustic emission microstructure to loudness perception and perceptual decision-making; this is strong evidence that physical cochlear fine structure directly shapes perceptual weighting.
