Contributions of motor skill development and physical activity to the ontogeny of executive function skills in early childhood

Because of executive function (EF) skills' importance for social, emotional, and academic success, there is strong interest in supporting their development in early childhood. Efforts to increase the duration and/or intensity of children's physical activity have been proposed as one promising approach. However, this proposal has been a source of debate, and too few studies have been conducted with young children to support recommendations in early childhood. Here, we provide a critical review of relevant studies. A recurring idea is that children's fine and gross motor development represents a sequence of goal-directed activities that serve to engage and practice their EF skills. The development of children's motor skills appears more strongly associated with EF skill development in early childhood than the frequency, duration, or intensity of their physical activity. We integrate these ideas into the larger literature and consider implications for research and practice.
