“…A fundamental assumption of binaural adaptation is that lateralization is dominated by onset ITD and ILD at high modulation rates, while post-onset information contributes little to subjects' perception. Correspondingly, TWFs measured in normal-hearing listeners for ITD and ILD carried by highrate acoustic click trains (e.g., 800 Hz, Brown and Stecker, 2010) or in bilateral CI users for high-rate electrical pulse trains (e.g., 600 Hz, van Hoesel, 2008a) generally show high weights at onset and uniformly low weights for individual post-onset clicks, although these and other recent studies of temporal weighting of ITD and ILD (e.g., Saberi and Antonio, 2003;Saberi et al, 2004;Stecker and Brown, 2010) also suggested reduced onset dominance for ILD relative to ITD-a finding in conflict with the notion of equal binaural adaptation for ITD and ILD . The nature of differences in the time courses of ITD versus ILD sensitivity, including the common finding of significant individual differences in sensitivity across listeners, remains an area of great interest to us and others at present (cf.…”
