Abstract excerpt
OBJECTIVE: Applying a probabilistic learning task we examined the influence of functional polymorphisms of the serotonin transporter gene (5-HTTLPR) and the D2 dopamine receptor gene (DRD2/ANKK1) on error and feedback processing by measuring electrocortical event-related potentials (ERPs) in 10- to 12-year-old children. METHODS: Three pairwise group comparisons were conducted on four distinguishable ERP...
