A correlational link between two aging-sensitive auditory tasks can dissolve once age is controlled.
Evidence
It should be noted, however, that the positive correlation found for the TIME and HUGGINS tasks was due predominantly to the consistent age effect in the both tasks (see Fig. 1 ). When the effects of age were partialled out, the correlation coefficient was not significantly different from zero (r = − 0.24, p = 0.191), implying that the positive correlation was due to underlying non-temporal factors that are sensitive to aging. A candidate for such a factor is frequency selectivity. It has been argued that (intermediately) resolved frequency components of the SSMC could contribute to the performance of the TIME task (Micheyl et al. 2010 ). Peripheral frequency resolution could influence the representation of interaural correlation across a frequency axis, which is the basis for the Huggins pitch. — Dijk, Pim van, Physiology, Psychoacoustics and…, 1082 (

It has been reported that sensitivities to the temporal structure and intensity of stimuli decline with age (e.g., Hopkins and Moore 2011 ). A population including young and elderly listeners would therefore exhibit a large variability of thresholds in the monaural tasks, which would lead to improved sensitivity of the correlation analyses and provide further insights as to the roles of monaural processing in ITD or ILD discrimination. — Dijk, Pim van, Physiology, Psychoacoustics and…, 1027 (
