Abstract
Electroencephalo-graphic records from right and left motor and occipital areas of 20 adult stutterers and 20 adult non-stutterers taken during silence and during speech were compared for evidence of unilateral and bilateral blocking of the a rhythm. The only statistically significant differences were as follows: an intergroup differentiation showing more bilateral blocking of the [alpha] rhythm in the occipital areas during speech of stutterers than of non-stutterers; an intragroup difference showing more bilateral blocking in stutterers during speech than during silence; and an interhemisphere difference during silence showing more blocking of the rhythm in the left occipital area of stutterers and in the right occipital area of non-stutterers. While the interhemisphere differences during silence seem to point to some physiological difference between stutterers and non-stutterers the investigation did not disclose the nature of this physiological difference.This publication has 4 references indexed in Scilit:
