  • Title: Hemispheric lateralization for speech perception in stutterers.
    Author: Dorman MF, Porter RJ.
    Journal: Cortex; 1975 Jun; 11(2):181-5. PubMed ID: 1149477.
    Abstract:
    Sixteen adult, right-handed, moderate-to-severe atutterers (12 males, 4 females) and 20 nonstuttering controls (10 males, 10 females) were given a dichotic nonsense-syllable test to determine hemispheric lateralization for speech. Both male and female stutterers evidenced right-ear advantages in syllable identification similar in magnitude to those found for normals. These data confirm other reports of no difference in cerebral speech lateralization for stutterers and nonstutterers and, therefore, lend no support to theories that relate stuttering to abnormalities in cerebral lateralization. Acknowledgments. This study was conducted while the authors were at the University of Connecticut, Storrs. The assistance of Dr. R. L. Webster, the staff of the Institute for Behavioral Research, and the Departments of Psychology and Linguistics at the University of Connecticut is gratefully acknowledged.
