Individual differences in adolescent self-control: The role of gene-environment interplay

Self-control - the ability to alter unwanted impulses and behavior to bring them into agreement with goal-driven responses - is key during adolescence. It helps young people navigate through the myriad challenges they encounter while transitioning into adulthood. We review empirical milestones in our understanding of how individual differences in adolescent self-control exist and develop. We show how the use of molecular genetic measures allows us to move beyond nature versus nurture, and actually investigate how both nature and nurture explain individual differences in self-control. By highlighting the role of gene-environment correlations and geneenvironment interactions, this paper aims to enthuse fellow researchers, with or without a background in genetics, to apply genetically sensitive designs too.
