Infant predictors of preschool and adult IQ: A study of infant twins and their parents.

The aim of this article is twofold. First, the usefulness of the midparent-midtwin design as a proxy for a longitudinal study was assessed. This design should prove effective in determining which of a nmber of infant measures are predictive of later IQ and thus are likely candidates for infant intelligence measures. Second, a true longitudinal study was conducted to examine the predictability of our infants measures in chidhood. Intelligence measures of the twins at ages 1, 2, and 3 years were collected. In this way, we could determine whether the infant variables that predicted midparent IQ help us as predictors of infants' IQ scores.
