Active Videogames to Promote Traditional Active Play: Increasing the Reinforcing Value of Active Play Among...

Exercise reinforcement predicts physical activity of children. Repeated exposures of physical activity may increase physical activity reinforcement (incentive sensitization). Active videogame (AVG) play produces light-to-moderate-intensity physical activity. Ideally, AVG play would transition to nonscreen-based active play through incentive sensitization of traditional active play (TAP), providing AVG does not increase sedentary videogame (SVG) reinforcement. Greater autonomy increases motivation toward traditional physical activity, but whether autonomy enhances incentive sensitization has not been studied. To determine whether autonomy over AVG play promotes incentive sensitization of TAP or SVG. Inactive children (ages 8-12; 5th-97th body mass index percentile) were provided with AVG and SVG for 6 weeks and assigned to either a high autonomy (n = 25) or low autonomy (n = 24) group, differentiated by AVG choice and more freedom over amount of play. Both groups played AVG 3 days per week. SVG were played ad libitum. Participants completed an operant responding task to measure the relative reinforcing value (RRV) of AVG versus SVG (RRV_{AVG vs. SVG}) and AVG versus TAP (RRV_{AVG vs. TAP}) at baseline, 6 weeks, and 10 weeks. RRV_{AVG vs. SVG} increased over time (P = 0.056) but did not differ by autonomy or autonomy × time (P = 0.184). RRV_{AVG vs. TAP} decreased over time (P = 0.033) but did not differ by autonomy or autonomy × time (P = 0.73). AVG play does not increase motivation toward SVG and increases motivation to play AVG relative to TAP. Providing higher autonomy did not promote incentive sensitization of play.
