Variability of Practice As an Interface Between Motor and Cognitive Development
International journal of sport and exercise psychology(2016)
Abstract
In this commentary, we highlight intriguing commonalities between the research areas of exercise and cognition and motor skill development and learning. While these two research domains have developed on separate tracks, the focus on variability of practice is central to both. We adopt a joint sport science and neuroscience approach to identify the characteristics of designed motor learning experiences that can impact brain plasticity and cognitive development. Novelty, diversity, effort, and successfulness seem essential ingredients to render learning experiences meaningful to this aim. All these characteristics belong to the construct of variability as it is conceived in the informational and ecological approaches to motor skill learning. To transition theory into practice, we discuss how variability of practice can impact cognitive and particularly executive function development. In this context, we address the role of flexibility training to support key transitions in the development of cognitive control, looking at the relation between repetition and change in physical activity in terms of trade-offs between costs and benefits of stability and flexibility. We conclude by reframing variability of practice into emerging models of embodied cognition, highlighting the potential of the proposed intersection of chronic exercise and cognition, cognitive development, and motor learning evidence to unwrap a new venue for sport sciences and quality physical education.
