Critical life-coping skills often develop during unstructured playtime, or playing without specific direction, according to Peter Gray, professor of psychology at Boston University. For example, playing in the garden or at the neighbourhood park helps children develop relevant social skills and problem-solving abilities, such as taking turns on the swings or establishing rules of a game. Gray argues that “children today are less free than they have ever been” and it is taking a psychological toll, urging parents to promote less screen time and more free playtime.
