Subject: Re: perception of rise/fall times From: Stuart Rosen <stuart(at)PHONETICS.UCL.AC.UK> Date: Sat, 5 May 2001 18:40:04 +0100Spurred by the inquiry from Dennis Phillips (and because I have seen the history of this issue being gradually forgotten), I would like to point out that the results of Cutting & Rosner (P&P, 1974, 16: 564-570) were shown conclusively to arise from errors in the specification of the stimuli. Pluck and bows are *not* categorically perceived! For the details see: Rosen, S. M. & Howell, P. (1981) Plucks and bows are not categorically perceived, Perception and Psychophysics 30: 156-158. A review article discussing this issue with more background is also available: Rosen, S. & Howell, P. (1987) Auditory, articulatory and learning explanations of categorical perception in speech. In: Categorical Perception, ed. S. Harnad.
