highly significantp = 0.0006
The Treatment*MAOA interaction was not significant across all delays, but RMANOVA across the shorter delays (2,4,8,16 s), completed by all but one subject, showed a highly significant interaction (F(1,23) = 9.27, p = 0.0006) and a significant fluoxetine effect in the hi-MAOA subgroup (post hoc comparison, p = 0.0003).
