Medium- and long-term effects of types of placement of the offspring of lower class families have been studied. The progeny of 28 mothers was reconstituted. The subjects were divided into three groups: 35 children abandoned and adopted early in privileged environments (A), 46 'biological mother-reared' children remaining in their disadvantaged social environments (B) and 21 children raised in institutions or foster homes (C). Analyses focused on IQ, scholastic performance and behaviour. Results show that the social environment has important effects: the differences between the three groups are very significant. For A and B groups tested in the schools, comparisons were made with the classmates. For the C group the effects of long-term emotional deprivation are superimposed on the effects of the social environment.
对下层阶级家庭子女安置类型的中长期影响进行了研究。对28位母亲的后代进行了重组。研究对象被分为三组：35名在优越环境中被早早遗弃并收养的儿童（A组），46名留在弱势社会环境中的“由亲生母亲抚养”的儿童（B组），以及21名在机构或寄养家庭中长大的儿童（C组）。分析集中在智商、学业成绩和行为方面。结果表明，社会环境有重要影响：三组之间的差异非常显著。对于在学校接受测试的A组和B组，与同学进行了比较。对于C组，长期情感剥夺的影响叠加在社会环境的影响之上。
