Does parental education have a moderating effect on the genetic and environmental influences of general cognitive ability in early adulthood?
Hereditary influences account for a substantial proportion of the variance in many cognitive abilities. However, there is increasing recognition that the relative importance of genetic and environmental influences may vary across different socioeconomic levels. The overall goal of the present study was to examine whether parental education has a moderating effect on genetic and environmental in...
متن کاملCommunity Influences on Cognitive Ability
Although the environment determines important individual differences in cognitive ability, most home environment variables that correlate with children's intelligence are more strongly associated with the pleiotropic effects of genes than with causal pathways of environmental transmission. Here, we demonstrate that community variables, a hitherto understudied set of constructs in research on co...

متن کاملGenetic influences on 'environmental' factors.
Childhood environment, social environment and behavior, leisure time activities and life events have been hypothesized to contribute to individual differences in cognitive abilities and physical and emotional well-being. These factors are often labeled 'environmental', suggesting they shape but not reflect individual differences in behavior. The aim of this study is to test the hypothesis that ...
متن کاملGenetic influences on four measures of executive functions and their covariation with general cognitive ability: the Older Australian Twins Study.
"Executive functions" (EF) is a multidimensional construct which encompasses many higher-order cognitive control operations, and is considered a potential mediator of age-associated changes in other cognitive domains. Here we examine the heritability of four measures of EF, and the genetic influences on their covariation with general cognitive abilities (GCA) from the Older Australian Twins Stu...
