Perinatal and medical information, growth, and the social background of 258 children who, in a prospective study, had superior intelligence at 7 years of age were reviewed. The subjects were divided into three categories on the basis of the results of psychological evaluation at age 7. Comparisons were made between those with superior (intelligence quotient greater than or equal to 120), average (IQ between 80 and 119), and low intelligence (IQ less than or equal to 79). A favorable parental social and educational background was the best correlate of superior intelligence in the children. Larger head size from 1 year of age was an early finding associated with superior intelligence. Greater height and weight, from 4 years of age were later findings. Correlations between psychological performance at ages 4 and 7 years were statistically significant. Perinatal factors and medical complications did not affect the intellectual status of children with superior intelligence.

Effects of prenatal hormone exposure versus pregnancy complications on sex-dimorphic behavior

et al. 1984

View full text Add to dashboard Cite

The existing literature on human subjects indicates demasculinization as an effect of prenatal exposure to various exogenous sex hormones, except for 19-nor progestogens. For the samples described in Ehrhardt et al. (1984), the current study examines whether the demasculinization can be explained by pregnancy complications. Corresponding covariates were constructed. In order to permit parametric analysis, the primary rating scales used previously were factor-analyzed and aggregated to form cluster scales where feasible. The factor analysis also demonstrated the existence of a general factor of sex-dimorphic behavior. Subsequent case-control comparisons by t test and by analysis of covariance for the general-factor and cluster scales showed that pregnancy complications do not explain the modest demasculinization effects of prenatal hormone exposure observed in females. A few paradoxical results emerged in males, likely to be due to chance.
