Abstract In a replication of a study by R. D. Kent (1973), Ss (the present authors) imitated synthetic stimuli from [u]^[i] and [i]^[ae] continua at 3 temporal delays. Acoustic analysis of the response vowels revealed similar patterns across delays. Both Ss showed clear evidence of nonlinearities in the stimulusesponse mapping and of preferred response formant frequencies, although strictly categorical responses were generally absent. It is suggested that vowel imitation responses reflect the joint influences of perceptual and articulatory factors.
