“…As much as genetic confounding needs to be considered when estimating environmental effects, 'environmental confounding' needs to be taken into account when estimating genetic effects (Krapohl et al, 2017;Young et al, 2018). Third, our findings show that environments are part of the pathway from genotype to phenotype (Kandler & Zapko-Willmes, 2017;Scarr & McCartney, 1983). Specifically, we found that genetic influences on children's educational attainment partly manifested through parenting; an environmentally mediated genetic effect.…”

This study tested implications of new genetic discoveries for understanding the association between parental investment and children's educational attainment. A novel design matched genetic data from 860 British mothers and their children with home-visit measures of parenting: the E-Risk Study. Three findings emerged. First, both mothers' and children's educationassociated genetics, summarized in a genome-wide polygenic score, predicted parenting --a gene-environment correlation. Second, accounting for genetic influences slightly reduced associations between parenting and children's attainment --indicating some genetic confounding. Third, mothers' genetics influenced children's attainment over and above genetic mother-to-child transmission, via cognitively-stimulating parenting --an environmentallymediated effect. Findings imply that, when interpreting parents' effects on children,

“…Yet a number of theoretical perspectives (e.g. Bouchard, 1997;Kandler & Zapko-Willmes, 2017;Scarr & McCartney, 1983) emphasize that genetic influences might lead people to certain environments, which in turn shape development. These sorts of systematic experiences may play an outsized role in generating associations.…”

Identifying causal relations from correlational data is a fundamental challenge in personality psychology. In most cases, random assignment is not feasible, leaving observational studies as the primary methodological tool. Here, we document several techniques from behaviour genetics that attempt to demonstrate causality. Although no one method is conclusive at ruling out all possible confounds, combining techniques can triangulate on causal relations. Behaviour genetic tools leverage information gained by sampling pairs of individuals with assumed genetic and environmental relatedness or by measuring genetic variants in unrelated individuals. These designs can find evidence consistent with causality, while simultaneously providing strong controls against common confounds. We conclude by discussing several potential problems that may limit the utility of these techniques when applied to personality. Ultimately, genetically informative designs can aid in drawing causal conclusions from correlational studies. Copyright

“…Gene-environment correlations can account for several fundamental findings of behavioral genetic studies (Kandler and Zapko-Willmes, 2017), as well as provide alternative explanations for mainstream developmental psychology findings (Barbaro et al, 2017a;Barnes et al, 2014). Geneenvironment correlation refers to the association between heritable phenotypic characteristics and nonrandom exposure to environmental experiences that are associated with that same phenotypic characteristic (Plomin et al, 1977).…”

“…Geneenvironment correlation refers to the association between heritable phenotypic characteristics and nonrandom exposure to environmental experiences that are associated with that same phenotypic characteristic (Plomin et al, 1977). In other words, genotypes are expressed in the environment (or outside the organism) via manifest behavior and psychological traits (Kandler and Zapko-Willmes, 2017). This is not to say that behavior is genetically determined, but rather it is to say that environmental experiences are not random and are prompted by an individual's genotype.…”

“…The importance of active gene-environment correlation increases with age as individual decision making and environmental control also increase. The implications of this change in the dominant type of gene-environment correlation throughout development can, in part, explain the increase in heritability estimates of a myriad of traits (most notably, intelligence) over development (Kandler and Zapko-Willmes, 2017;Plomin et al, 2016).…”
