The pattern‐transformation model of pitch perception [Wightman, J. Acoust. Soc. Am.54, 407–416 (1973)] can successfully predict the pitch of many types of complex‐tone stimuli. In addition, the model provides numerical estimates of pitch “strength.” In order to test these latter predictions we assumed that performance in a musical interval‐recognition paradigm [Houtsma and Goldstein, J. Acoust. Soc. Am.51, 520–529 (1972)] is a direct indicator of pitch strength; the better the performance, the stronger the pitch. Thus, Houtsma and Goldstein's data can be used to evaluate the pitch‐strength predictions of the model To do this, a set of stimuli was defined such that all stimuli in the set led to the same level of performance in the interval‐recognition paradigm; the stimuli lay on one of Houtsma and Goldstein's “constant‐performance contours.” Then pitch‐strength predictions were generated for these stimuli. If our assumption is valid, all the stimuli should have the same predicted pitch strength. Except for stimuli of low fundamental frequencies, the predictions follow this pattern. The failure with low‐fundamental stimuli seems to be a result of our initial assumption that spectral resolution (critical bandwidth) is a constant percentage of frequency (i. e., that the peripheral analyzer has constantQ). If the constantQassumption is relaxed, so that our assumed critical bandwidths agree more closely with available data, the performance of the model is much improved.
