Klein su: Academic achievement Psychology of adoptees Cognitive development Intelligence levels sug: subj: Academic achievement Psychology of adoptees Cognitive development Intelligence levels ab: This meta-analysis of 62 studies (N = 17,767 adopted children) examined whether the cognitive development of adopted children different from that of (a) children who remained in institutional care or in the birth family and (b) their current (environmental) nonadopted siblings or peers. Adopted children scored higher on IQ tests than their nonadopted siblings or peers who stayed behind, and their school performance was better. Adopted children did not differ from their nonadopted environmental peers or siblings in IQ, but their school performance and language abilities lagged behind, and more adopted children developed learning problems. Taken together, the meta-analyses document the positive impact of adoption of the children's cognitive development and their remarkably normal cognitive competence but delayed school performance.
