Eight experiments examined the effects of placing a sequential organization cue (the frequency proximity between successive tones) into competition with various binaural cues. The sequential organization of an alternating pair of monaural pure tones (A and B) was found to oppose the effect of a contralateral noise burst (synchronous with B) to delateralize B's perceived position and to distort its perceived purity. Similarly, the sequential organization of a monaural tone with the same-ear component of a dichotic tone was found to often oppose the perceptual integration of the components of the dichotic tone. These findings were interpreted as suggesting that sequential cues compete with certain binaural cues during lateralization and dichotic integration decisions. However, sequential cues were found not to influence the fusion of identical sinusoids presented at opposite ears. Thus, binaural fusion appeared to occur independently of sequential organization processes. These findings were discussed in terms of levels and mechanisms of processing, and of ecological demands.
