Hand preference, prematurity and developmental outcome at school age.
Neuropsychologia, 30 (5):
483--494 (May 1992)Abstract
Information was obtained on the hand preference of 88 premature and 80 matched full-term children at 7-8 years old. These children were also evaluated for neurologic status, IQ, attention-deficit hyperactivity disorder, and learning disabilities. Although the difference on hand preference was not significant, 12\% more of the premature children than the full-term children were left- or mixed-handed. Results showed that, among premature children, there is an association between non-right-handedness and cognitive and behavioral deficits and that left-handed children show relative clumsiness with the non-preferred hand.
