富勒顿虚拟双胞胎研究自1991年以来一直在评估一个不寻常的同胞的行为。虚拟双胞胎（Virtual Twins，简称VT）是指从婴儿期起就在一起长大的同龄、不相关的兄弟姐妹。他们复制了双胞胎的养育情况，但没有遗传联系，从而能够直接评估共同的环境对行为的影响。基于142个VT对（7.87岁，SD=8.22）的增加样本，提供了IQ数据的更新分析。组内相关系数为0.28（智商）和0.11（分测验），表明环境对智力的影响不大。从双胞胎，同胞，同伴和姐妹（TAPS）项目，研究虚拟双胞胎和其他亲属关系的调查结果进行说明。
The Fullerton Virtual Twin Study has been assessing the behaviors of an unusual sibship since 1991. 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 (7.87years, 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.
