(1) Irrelevant between-signal variation in the fundamental frequency of complex tones was introduced into discrimination tests of relevant within-signal frequency differences. (2) Correspondingly, irrelevant within-signal variation in the fundamental frequency of complex tones was introduced into discrimination tests of relevant between-signal frequency differences. The effect of (2) was substantially larger than that of (1), suggesting the relative primary of within-signal processing over between-signal processing for the fundamental frequency of complex tones.
