This study evaluated whether a theory-based intervention in physical education (PE) designed to train selfcontrol may positively impact children's quick-temperedness and disruptiveness and whether changes in executive functions (EFs) may be a correlate or antecedent of such effects. One hundred and sixteen children aged 8-9 years participated in a 2-year intervention and completed three assessments at baseline, 6-and 18-month follow-ups in quick-temperedness and disruptiveness, hot and cool EFs. After the intervention, children in the intervention group showed lower quick-temperedness and disruptiveness and improvement in hot EF. Changes over the intervention period were moderately associated and showed marginal evidence of causal ordering, suggesting that designed PE may benefit self-control through a possible linkage to hot EF improvement.Self-control plays an important role in healthy personal and social development, as it represents a key to health, wealth, safety, and success in multiple life domains (Moffitt et al., 2011). For this reason, the development and study of interventions to improve self-control as early as childhood is viewed as a priority not only in basic research on the self but also in applied research with practical value for educators, parents, and coaches involved in school-, family-, and community-based interventions (Berkman, Graham, & Fisher, 2012). There are two main approaches to fostering self-control (Beames, Schofield, & Denson, 2018): one through training-specific cognitive functions (i.e., cognitive approach) and the other through training behavioral and socioemotional self-regulation processes that rely on self-control resources (i.e., energetic approach; Figure 1).
Fostering Self-Control Through Executive Function TrainingExecutive function (EF) is an umbrella term comprising a set of higher-level cognitive control processes which enable one to self-direct behavior toward a goal, adapt it to novel situations breaking out of habitual thoughts and actions, flexibly plan, and make decisions (Diamond, 2013).
