Comparison of hand preference in trainable mentally handicapped and nonhandicapped children

Hand preference was compared in 22 trainable mentally handicapped and 22 nonhandicapped children (Mage 78.00 mo.). Significant differences were found, showing the nonhandicapped group had a stronger preference when presented 10 hand-choice items from The Harris Tests of Lateral Dominance. In addition, stronger lefthandedness characterized the handicapped group, supporting previous research.
