For the right VLPFC source, there were significant main effects of cultural group, F(1, 35) = 13.96, p < 0.001, ηp2=0.29 (Chinese M = 0.27, SE = 0.016; European M = 0.19, SE = 0.014), go/no-go condition, F(1, 35) = 197.52, p < 0.001, ηp2=0.90 (go M = 0.12, SE = 0.007; no-go M = 0.33, SE = 0.017), and interval, F(4, 140) = 21.08, p < 0.001, ηp2=0.38 (250–300 ms M = 0.19, SE = 0.011; 300–350 ms M = 0.23, SE = 0.012; 350–400 ms M = 0.24, SE = 0.011; 400–450 ms M = 0.23, SE = 0.010; 450–500 ms M = 0.24, SE = 0.010) with greater activation for Chinese children; no-go trials; and the interval of 250–300 ms vs. all others. These main effects were qualified by a Cultural group × Go/no-go condition interaction, F(1, 35) = 6.91, p < 0.05, ηp2=0.17, a Go/no-go condition × Interval interaction, F(4, 140) = 25.28, p < 0.001, ηp2=0.42, and a Cultural group × Go/no-go condition × Interval interaction, F(4, 132) = 3.10, p < 0.05, ηp2=0.09. Post hoc tests revealed that the difference between go and no-go trials (i.e., no-go > go) for this right VLPFC source was larger for Chinese-Canadian children than for European-Canadian children, that the difference between go and no-go trials was largest between 350 and 400 ms, and that the Cultural group × Go/no-go condition interaction was especially pronounced for the two intervals between 300 and 400 ms.
