Abstract: The distributions of handedness in the deaf is as marked as that of thepeople with hearing and the distributions of handedness in congenitally andacquired deafness are almost the same. It has been shown that earlyauditory experiences do not affect the distributions of handedness. Our re-sults also show that there is a close relationship between handedness andhand-using sign language. The right handers all use their right hands for theprimary movements of one-handed and two-handed sign language, but thecontrary is the case with the left handers.
