虚拟双胞胎（Virtual Twins，简称VT）是一种从婴儿期起就一起长大的同龄无血缘关系的兄弟姐妹，他们复制了孪生关系，但没有遗传上的亲缘关系。2005年，一份来自正在进行的富勒顿虚拟双胞胎研究的报告发现，智商组内相关系数为0.26（p<0.01，n=113对），组内差异为13.22。该研究中VT的平均年龄为8.10岁（SD=8.56，范围：4.01-54.84岁）。有机会重新测试成员的43 VT对，1.70-8.96年后，他们的时间1评估，允许额外的分析遗传和环境的影响下的一般智力发展。VT IQ相关性降低，配对内差异增加，这与遗传和/或非共享环境影响增加以及共享环境对整个儿童期一般智力发育的影响减少一致。
Virtual twins (VTs) are same-age unrelated siblings reared together from infancy who replicate twinship, but without the genetic relatedness. A 2005 report from the ongoing Fullerton Virtual Twin Study found an IQ intraclass correlation of .26 (p<.01, n=113 pairs) and a within-pair difference of 13.22 IQ points. The average age of VTs in that study was 8.10 years (SD=8.56, range: 4.01–54.84 years). An opportunity to retest members of 43 VT pairs, 1.70–8.96 years after their time 1 assessment, allowed additional analyses of genetic and environmental influences underlying general intellectual development. A decrease in the VT IQ correlation and an increase in the within-pair difference were indicated, consistent with increasing genetic and/or non-shared environmental influences and decreasing shared environmental influence on general intellectual development throughout childhood.
