| Abstract | Six normally hearing 19-27 yr olds were presented nonspeech stimuli which varied according to intensity and rise time. Subjects were required to identify stimuli by one of these dimensions. Identification time for the dimension of rise time increased when there was irrelevant variation in intensity; however, identification of intensity was unaffected by irrelevant variation in rise time. When the 2 dimensions varied redundantly, identification time decreased. This pattern of results is remarkably similar to that obtained by C. C.Wood (see PA, Vol 53:194) when stimuli were varied along a linguistic and a nonlinguistic dimension. It is suggested that the mechanisms underlying the auditory-phonetic transformation cannot be accounted for solely in terms of a nonlinguistic-linguistic distinction. This transformation may be based on acoustic properties alone, on the coding of sounds within a hierarchically organized system, or on the interaction of acoustic properties with such a system. |
