Differences in acoustic memory effects between consonants and vowels have led to the assumption that transience of the acoustic signal may affect persistence in immediate memory [Crowder, J. Verb. Learn. Verb. Beh.10, 587–596 (1971); Crowder, J. Exp. Psychol.98, 14–24 (1973)]. The present study was undertaken to determine whether less transient consonants are more persistent than natural stop consonants. Stop stimuli with lengthened F2 and F3 transitions employed in a perceptual study reported on at the last meeting of this society were utilized. Data resulting from stimulus suffix and recency effect tests indicate that these stimuli give results characteristic of short‐transitioned stops. Thus, transience is not a factor in acoustic storage.
