DRD4 and Anxiety: The DRD4 × maternal regulation × age three-way MANOVA for CCQ aggressiveness and CCQ anxiety revealed significant main effects for maternal regulation (F(2,82) = 3.18, p = 0.050, η2 = 0.071) and age (F(2,82) = 6.91, p = 0.002, η2 = 0.144), a marginal main effect for DRD4 (F(2,82) = 3.05, p = 0.053, η2 = 0.069), and a significant three-way interaction between DRD4, maternal regulation and age (F(2,82) = 5.19, p = 0.008, η2 = 0.075).
