In this study we examined the potential of technology-enhanced educational programs for young children lagging behind in emergent literacy skills. Differential effects of technology-enhanced educational programs for poor performers were tested in a randomized controlled trial. Our previous study showed that children with a dopamine-related genetic polymorphism – DRD4 7-repeat – are more susceptible to their learning environment than children without this polymorphism, serving as a proxy for the dopamine-system related genetic pathway. In the current study, we aimed to replicate and extend these results in a sample of 583 kindergarteners from 136 schools. As predicted by the genetic differential susceptibility theory, carriers of the DRD4 7-repeat allele profited significantly from Living Books ( d = 0.75), whereas non-carriers did not benefit ( d = 0.02). Living Letters did not show a Gene × Environment interaction. We discuss why carriers of DRD4 7-repeat allele particularly benefit from Living Books . [ABSTRACT FROM AUTHOR]
