However, the preceding context effect are larger in children as they perform substantially worse compared to adults as Go trials increase (Durston et al. 2002). These findings suggest that overcoming increasingly difficult prepotent motor responses, as well as its underlying inhibitory control neural circuitry, continues to develop across adolescence. Furthermore, sex differences have been reported in response inhibition performance in children (Bezdjian et al. 2009) and brain activity in adolescents (Rubia et al. 2013), but sex differences in the preceding context effect and how it develops remain unknown. Here, we examine how age and sex influence overcoming prepotent responses of increasing difficulty in adolescents.
