Abstract
In a study of 29 stutterers at the Univ. of Iowa, Ritzman was unable to replicate most of Palmer''s and Gillette''s studies. No significant differences were found for heart rate, but the study tended to confirm the previous findings that $ stutterers have less marked sinus arrhythmia than their controls. The author believes that such studies are of more value when interpreted as the physiol. consequences of stuttering than as studies of etiology.
