Philip Zelazo, a professor in the Institute of Child Development, was featured in an article in Vox that discussed whether 16-year-olds should be allowed to vote. The article highlighted Zelazo’s research on executive function skills, which according to Zelazo, are “the brain-based attentional skills required for goal-directed problem solving [like voting].” Zelazo’s research suggests that the executive function skills used when voting are almost fully developed by age 15.
