The Fullerton Virtual Twin Study has been assessing the behaviors of an unusual sibship since 1982. Virtual twins (VTs) are same-age, unrelated siblings reared together since infancy. They replicate the rearing situation of twins but without the genetic link, enabling direct assessment of shared environmental effects on behavior. An updated analysis of IQ data, based on an increased sample of 142 VT pairs (7.87 years, SD=8.22), is presented. Intraclass correlations of .28 (IQ) and .11 (subtest profile) indicated modest shared environmental influences on intelligence. Findings from the Twins, Adoptees, Peers and Siblings (TAPS) project that studies virtual twins and other kinships are described.
自1982年以来，富勒顿虚拟双胞胎研究一直在评估一个不同寻常的同胞群体的行为。虚拟双胞胎（VTs）是自幼一起抚养长大的同龄非亲属兄弟姐妹。他们复制了双胞胎的抚养环境，但没有基因联系，从而能够直接评估共享环境对行为的影响。本文基于142对虚拟双胞胎（7.87岁，标准差=8.22）的增加样本，对智商数据进行了更新分析。组内相关系数为0.28（智商）和0.11（子测试概况），表明共享环境对智力有适度影响。本文还描述了双胞胎、领养者、同伴和兄弟姐妹（TAPS）项目的研究结果，该项目研究虚拟双胞胎和其他亲属关系。
