Links between DRD4, executive attention, and alphabetic skills in a nonclinical sample

Abstract excerpt

BACKGROUND: The dopamine D4 receptor gene (DRD4) has been linked to attention deficit hyperactivity disorder (ADHD) and reading disorders. In this study, we examined whether diminished anticipatory dopamine cell firing - typical of the long variant of the DRD4 allele - is related to emergent and advanced alphabetic skills, and whether executive attention is a mediator between this allele and alphabetic skills....
