DLF thresholds reflect temporal fine structure processing, not frequency selectivity

Evidence

The results showed that the SNHL listeners had reduced frequency selectivity, but intact temporal resolution ability, while the ANSD listeners had degraded temporal resolution ability, but intact frequency selectivity. In comparison with the SNHL listeners, the ANSD listeners had severely degraded ability to process the FS cues and thus their ability to perceive lexical tone mainly depended on the ability to use the E cues. These results suggested that, in comparison with the detrimental impact of the reduced frequency selectivity, the impaired temporal resolution may lead to more degraded FS processing in pitch perception. — Dijk, Pim van, Physiology, Psychoacoustics and…, 3377 (#corroborates, via linked claim)

For the low-frequency stimulus, the listeners were required to detect a common upward frequency shift (Δf Hz) imposed on the individual components of the SSMC with the spectral envelope remaining unchanged (Moore and Sek 2009 ). It was assumed that the listeners based their judgments on pitch changes, reflecting the temporal fine structure encoded as the pattern of neural phase locking. — Dijk, Pim van, Physiology, Psychoacoustics and…, 1043 (#corroborates, via linked claim)
