关于一般认知能力（g）的遗传学，比心理学中的任何其他特征都要了解得多。最近关于遗传的研究结果包括以下三个例子：（1）遗传性在整个生命周期中增加;（2）认知测试中表现的遗传性与测试对agfactor的加载密切相关;（3）遗传对学业成就的影响与遗传对认知能力的影响大致重叠。遗传学研究的这一部分致力于研究正常范围内个体差异的病因学。关于分布高端的遗传学知之甚少。在认知能力的正常范围内发现遗传性并不意味着高能力也是遗传的。然而，第一项针对高智商儿童的双胞胎研究使用了一种新技术，分析了极端群体与其他群体之间的平均差异，表明高智商与正常范围内的个体差异一样具有遗传性。我们目前正在进行一项分子遗传学研究，试图确定有助于高能力的特定基因。
More is known aboul the genetics of general cognitive ability (g) than any other trait in psychology. Recent findings on the genetics ofginclude the following three examples: (1) heritability increases throughout the lifespan; (2) heritabilities of performance in cognitive tests are strongly correlated with the tests' loadings on agfactor; and (3) genetic effects on scholastic achievement largely overlap with genetic effects on cognitive ability. This body of genetic research addresses the aetiology of individual differences in the normal range. Much less is known about the genetics of the high end of the distribution. Finding heritability in the normal range of cognitive ability does not imply that high ability is also genetic in origin. However, the first twin study of high IQ children, which uses a new technique that analyses the average difference between extreme groups and the rest of the population, suggests that high IQ is as heritable as individual differences in the normal range. We are currently engaged in a molecular genetic study that attempts to identify specific genes that contribute to high ability.
