Dichotic right-ear advantages with 'bleats'.

Synthetic CVs competed against 'bleats' (second and third formant transitions, both kindly supplied to us by D. Pisoni and colleagues) alternately in the right and left ears of 10 subjects. Both right and left ears were suppressed by the presence of the bleat in the other ear, but the left ear suffered more interference than the right ear. The nonsemantic and unintelligible nature of the bleats, coupled with their ability to generate an REA when competing against CVs, heightens the importance of acoustic factors in the dichotic right-ear advantage for CVs. However, the results do not suggest that there are no other contributing factors to the REA, and should not be so construed.
