Abstract
Examined the relationship among handedness, hair and eye color, and stuttering. A survey of 199 7-57 yr old stutterers asked questions about handedness, original hair color, gender, and age. 49 Ss had blond hair; 69 Ss had blue eyes. Results indicate that stutterers were more non-right-handed than nonstutterers. For this group of stutterers, disfluency severity was greater among those with blond hair and blue eyes. Stuttering severity was also related to gender, with a greater percentage of males being rated as severe, while a larger percentage of the females were identified as being very severe. It is suggested that the observed findings may be due to the influence of testosterone and hypopigmentation factors. (PsycINFO Database Record (c) 2002 APA, all rights reserved)
