Ask people who grew up in the 1960s or 1970s about their childhood, and many will describe long afternoons outside with friends and few adults around. It can sound like simple nostalgia. A Boston College psychologist says it was much more than that.
In short
- Peter Gray is a psychologist and research professor at Boston College.
- In 2023, he and two colleagues published a review of the evidence in The Journal of Pediatrics.
- They link the rise in children’s mental health problems to a decline in independent activity.
- Gray dates a key shift, the fear of letting kids outside alone, particularly from the 1980s.
What changed
Gray has spent years studying play. In an interview with NPR, he described “a continuous decline in children’s opportunities to play freely” over the past several decades.
The 2023 review he led puts it in its very title: “Decline in Independent Activity as a Cause of Decline in Children’s Mental Wellbeing: Summary of the Evidence.”
In the interview, Gray points to two causes. First, an idea took hold: “we began to develop the view that children develop best when they are guided and controlled by adults.” Then came a change in parenting: “beginning particularly in the 1980s, we developed a fear of allowing children to be outdoors unguarded by an adult.”
The numbers behind it
The review, written with David Lancy of Utah State University and David Bjorklund of Florida Atlantic University, gathers striking figures, as ScienceDaily summarized. The average U.S. school year grew by five weeks between 1950 and 2010. Homework, once rare in elementary school, is now common even in kindergarten. And by 2014, recess in elementary school averaged about 27 minutes a day, with some schools offering none at all.
The review also points to school pressure. The researchers suggest that the fear of academic failure may itself be a direct source of distress for children, on top of the lost free time.
Why that freedom mattered
For the researchers, time spent away from adult control isn’t wasted. Even risky play, like climbing high in a tree, can help children build self-confidence and reduce anxiety later on. “Research, as well as everyday observation, indicates that play is a direct source of children’s happiness,” Bjorklund said.
What worries them is how quietly it happened. The decline in independent activity, and with it children’s mental wellbeing, “has crept up on us gradually, over decades,” Bjorklund said. For people who grew up with that freedom, it’s a reminder that some childhood memories weren’t luck. It’s the kind of life lesson stories like the family that lived cut off in the Siberian forest also make us think about.
The limit
This is a review of existing research, not a single experiment, and it describes a broad trend rather than every family. Children’s mental health has other causes too. The researchers don’t say childhood was better in every way decades ago; they point to one specific loss, time to play and act independently. Psychology often hides in everyday habits, like cleaning the kitchen at night.
That’s the story.
