Conflict control reflects an individual’s goal-directed cognitive control and self-regulation behaviors, and the neurodevelopment related to conflict control is crucial for the development of cognitive and emotional abilities in children. The current study enrolled preadolescent children and adults, who completed the Simon and Stroop tasks in emotional and non-emotional contexts with simultaneous electrophysiological recordings. The behavioral findings showed that adults had faster response speed and better conflict control performance compared to children, and children’s reaction time could be affected by emotional information. During the neural processes of conflict detection and conflict resolution, children generally had longer N2 latency for the monitoring process on conflicts and devoted more neural efforts with larger P3 amplitudes to detect and execute resolution control on the conflicts than adults did. Moreover, it was currently found that participant’s performance speed and neural process speed of N2 and P3 latencies during conflict monitoring and resolution could be influenced by the interaction between the types of stimulus-stimulus and stimulus-response conflicts and the contexts of emotional context and non-emotional contexts. The current study elucidates the children’s neurodevelopment effects of cognitive control on varied types of conflicts in both emotional and non-emotional contexts.
