Abstract
Previous research has shown that a signal which is one of two pure tones will be less detectable than a signal that is of constant, known frequency throughout. Similar results were obtained in the present study using pulse train signals with identical energy spectra but different pitches. This finding cannot be attributed to the “mistuned” critical-band mechanism postulated in the single-band [W. P. Tanner Jr. and R. Z. Norman, IRE Trans. Prof. Group Inf. Theory PGIT-4, 222–227 (1954)] and multiple-band [D. M. Green, J. Acoust. Soc. Am. 30, 904–911 (1958)] models of selective auditory attention. Our subjects performed as if they could selectively attend to phase, and/or periodicity pitch cues in order to optimize the detectability of anticipated signals.
