Segal, Nancy L.
Journal of Educational Psychology, v92 n3 p442-48 Sep 2000
Virtual twins are unrelated siblings of the same age who are reared together from early infancy (UST-SA). Study uses a sample of 90 UST-SA pairs to comparatively assess the similarity of IQ subtest profile correlations for UST-SAs and twin pairs. Findings support explanatory models of intelligence that include genetic factors, demonstrating that shared environments have modest effects on intellectual development.
