Hand Preference And Motor Functioning In Children With Autism

J Autism Dev Disord 2001 Jun;31(3):265-77
Hauck JA, Dewey D.
University of Calgary, Alberta, Canada.

This study examined three theories that have been proposed to
explain
the high rates of ambiguous hand preference in young children with
autism.
Twenty children with autism were matched with 20 children with
developmental
delays and 20 normally developing children. The groups were compared on
measures of hand preference and motor skills.
Results indicated that the lack of development of a hand
preference in
children with autism was not a direct function of their cognitive
delay, as
the children with developmental delays showed a dissimilar pattern of
hand
preference. The lack of a definite hand preference in the children with
autism was also not due to a lack of motor skill development, as the
children with developmental delays displayed similar levels of gross
and
fine motor skills without the accompanying lack of a definite hand
preference.
The finding that children with autism with a definite hand
preference
displayed better performance on motor, language, and cognitive tasks
than
children with autism who did not display a definite hand preference,
however, provided support for the bilateral brain dysfunction
hypothesis.
