Aerobic Fitness And Cognitive Development: Event-Related Brain Potential And Task Performance Indices Of Executive Control In Preadolescent Children, Jason R. Themanson, Charles H. Hillman, Sarah M. Buck, Matthew B. Pontifex, Darla M. Castelli

Jason R. Themanson, Ph.D

The relationship between aerobic fitness and executive control was assessed in 38 higher- and lower-fit children (M_age = 9.4 years), grouped according to their performance on a field test of aerobic capacity. Participants performed a flanker task requiring variable amounts of executive control while event-related brain potential responses and task performance were assessed. Results indicated that higher-fit children performed more accurately across conditions of the flanker task and following commission errors when compared to lower-fit children, whereas no group differences were observed for reaction time. Neuroelectric data indicated that P3 amplitude was larger for higher- compared to lower-fit children …
