Processing interaction between two dimensions of nonphonetic auditory signals.

Abstract
In 1974 Wood proposed a hybrid serial-parallel model to account for the within-stimulus interactions between the acoustic cue of "pitch" and the phonetic cure of "place." Three of the five experiments in this paper replicate the Wood findings with analogous, clearly nonphonetic stimuli and thus refute Wood's implicit assumption of the involvement of any uniquely phonetic processes as factors in his results. The experiments in this paper demonstrate that the patterns of interaction found by Wood are independent of the experience of the subjects, the order of cue presentation, and whether the cues are presented simultaneously or sequentially. We conclude that the given patterns of interaction are general characteristics of the auditory system. These characteristics probably are not related to backward or forward "recognition" masking but may be a function of several other general factors.
