Expertise and Deliberate Practice
Deliberate practice (DP) is a fairly popular topic when it comes to discussing expertise in sports and other professions. So what is DP?
Ericsson (2008) originally constructed the definition of DP to have the following components:
Individual active engagement
Training crafted by a coach, teacher, or similar
Dedicated to the improvement of a particular action
Integration of immediate feedback
Space for problem-solving and evaluation
Repetition of the action to cultivate the action

Definition of Expertise with Age
Expertise in sports is a complex process and, when talked about, can elicit many different thoughts, comments, and feelings. So what happens when we bring age into the picture? What happens to the definition of expertise? What happens when we consider physiological constraints, psychological processes, and the experience of aging?

Expertise, Mental Practice and Nature or Nurture
Hebb (1949) wrote that expertise “is a product of 100% nature and 100% nurture.” Interesting statement to make and fun to think about. What about the nature versus nurture argument can we use to learn about sport expertise?
