The effect of a metronome on the speech of young stutterers: A comment on Greenberg's paper

Abstract

Greenberg's recent study and conclusion that "it is the presence of the metronome rather than the instructions to pace one's speech with it that is the important factor" are questioned on methodological grounds. The use of a single metronome rate renders the study invalid as a test of the servo model of speech control. Individual differences in the preferred metronome rate for rhythmic speaking are marked and must be taken into account if meaningful conclusions are to be drawn from the data. © 1971 Academic Press, Inc.
