In follow-up psychological examinations of two groups of premature same-sex twins in preschool and school age (18 pairs with dissimilar and 15 pairs with similar birth weight), intelligence, visual and auditory perception, and drive, were evaluated.

The twins with lower birth weight usually attained lower IQs than their cotwins with higher birth weight, and nearly as a rule had poorer IQs of Verbal and Performance Scales. They also more often were hyperactive and had concentration difficulties. There were no differences in visual and auditory perception.
