Incentivizing physical activity using token reinforcement with preschool children.

We combined several single-subject designs to assess the effects of contingent and noncontingent token reinforcement on moderate-to-vigorous physical activity (MVPA) exhibited by 4 preschool-aged children. Higher overall levels and longer bouts of MVPA reliably occurred when tokens were delivered contingent on MVPA for 3 of the 4 children when compared to baseline (no token) and for 2 of the 4 children when compared to noncontingent-token conditions. The present study demonstrated that the delivery of tokens contingent on MVPA can increase and maintain MVPA exhibited by preschool-aged children, resulting in more MVPA than in baseline conditions and conditions in which tokens are awarded without respect to MVPA.

Adult attention and interaction can increase moderate-to-vigorous physical activity in young children.

Evidence suggests that physical inactivity is prevalent among young children. To combat this, one recommendation for caregivers is to become actively involved in their child's physical activities. However, this general recommendation does not specify how or when a parent should become involved.
