ITD task performance does not share the same inter-individual efficiency factor as temporal-structure tasks.

Evidence

Despite a relatively large number of participants and greater range of threshold values in the TIME task, however, we failed to find a correlation between the ITD and TIME tasks for the low-frequency stimulus. The thresholds for the HUGGINS task showed a significant positive correlation with those for the TIME task (r = 0.50, p = 0.004), but not with those for the ITD task (r = 0.11, p = 0.553). This suggests that the performances of the TIME and HUGGINS tasks capture inter-individual variation of the efficiency of temporal-structure processing, but that of the ITD task is determined primarily by other factors. — Dijk, Pim van, Physiology, Psychoacoustics and…, 1081
