Nexxo-training combines the use of the Nexxo touchscreen application (go/no-go and stop signal tasks) with procedural metacognitive strategies. The present paper reports a test of Nexxo's impact on children aged 6–7 and 8–9 years. We conducted a randomized active-controlled trial involving 108 typically-developing children: 1st grade (N = 61, M = 6.46 years, SD = 0.35) and 3rd grade (N = 47, M = 8.5 years, SD = 0.27), randomly assigned to: (1) experimental, (2) active-control, or (3) passive-control groups. A 2-month follow-up was carried out after the intervention. The 3rd grade experimental group displayed a significant reduction in attentional problems at follow-up compared to both control groups. Executive Function problems were also reduced at follow-up in the experimental group. Participants in this group improved in Supervision (self-monitoring) at post-intervention and follow-up compared to passive-controls. Although group effect was not significant at t1, it was significant at post measures in experimental group compared to passivecontrols. Nexxo-training revealed a trend-level improvement in attention and executive functions for children in the 3rd grade. Rossignoli-Palomeque, T., Pérez-Hernández, E., González-Marqués, J.
