The main effect of response portion was non-significant for the averaged-peak amplitudes ( F (1,55) = 0.244, p = 0.624), but marginally significant for the latencies ( F (1,55) = 3.77, p = 0.057), reflecting the fact that the averaged-peak latencies were slightly longer for the steady-state than for the transition portion (Fig. 3a , bottom right panel).
At the lower noise level, however, where the latency changes could be evaluated for all frequency bands, there was a marginally significant tendency for the latency changes to increase towards higher-frequency bands, such that, in the highest band, the change was both significant and comparable in size with the corresponding broadband latency change (note, however, that, as the amplitude of the highest frequency band was strongly reduced, even at the lower noise level, its latency change cannot have contributed substantially to the corresponding broadband latency change).
Unlike the latencies of the broadband response, which had shown highly significant main effects of noise condition at both noise levels (see above), the derived-band latencies showed no main effect of noise condition at either noise level (both p ≥ 0.105).
