The Science of Make-Believe: What Your Kid's Wild Imagination Is Actually Building

My kids converted our living room into a fully operational hospital for stuffed animals last Tuesday. There was a surgical suite behind the couch, a recovery ward on the hardwood floor (two bath towels, very sterile), and a billing department that charged Monopoly money at rates that would make an actual hospital blush. The stuffed giraffe with the wobbly neck was apparently the most critical case. They had been at it for forty-five minutes while I tried to answer emails two feet away. Eventually I gave up and just watched.

Imagine watching that scene with the research on play in mind. We can see children inventing characters and negotiating a story. We cannot watch their brains change or infer a clinical benefit from a game, however elaborate the stuffed-animal hospital becomes.

Because here's what we consistently get backwards about creative activities: we treat them as the reward for finishing the real stuff, when the evidence suggests they might actually be the real stuff.

What Imaginative Play Is Actually Training

Research on school programs and reading can help us think about children's learning. It cannot tell us exactly what a particular living-room game is doing to a child's brain.

A randomized study of public Montessori preschool found advantages in several measured skills at the end of kindergarten, including executive function and theory of mind, the ability to understand another person's perspective (Lillard et al., 2025). It evaluated a school model with many components, not pretend play by itself. We cannot attribute the results to one feature or promise that a home activity will reproduce them.

Children inventing a stuffed-animal hospital are practicing a story together. That is something to enjoy without needing to measure a cognitive gain.

The Surprising Science of Reading Aloud

If imaginative play is one lane of creative development, shared reading aloud is another. And the data here is frankly more striking than I expected.

A 2025 study published in the journal Intelligence by Batini and colleagues ran three independent cluster-randomized controlled trials in Italian elementary and middle schools. Treatment schools replaced one hour of standard language instruction per day with teacher-led reading aloud sessions over four months. Children in the reading-aloud condition showed significantly stronger development on two measures of general intelligence compared to controls, across all three independent trials (Batini, 2025). The results were consistent enough that the Tuscany regional government introduced one hour per day of reading aloud in public schools.

These results concern a sustained, teacher-led school program. They do not establish how much an individual child will benefit from an occasional bedtime story.

Shared reading can involve voices, suspense, questions, and imagined characters. Those are ways to enjoy a story together. This study does not establish that any one of them caused the measured changes.

Worth noting: the Batini (2025) effects held across elementary and middle school. If your eight-year-old still wants you to read to them, that is not regression. That is a good use of everyone's time.

Moving, Making, and Mental Health

There is a third dimension of creative development we under-discuss: the body.

Dance, drama, active physical play, and the particular brand of running-around-while-narrating-an-elaborate-story-to-yourself that seven-year-olds specialize in -- these movement-based creative activities show up in the mental health literature in ways that deserve more attention.

A review of physical activity in typically developing children and adolescents found possible mental health benefits, with low-quality evidence and important methodological limitations (Fu et al., 2025). It did not establish that every form of imaginative play produces the same effects, and it excluded children with diagnosed psychiatric disorders.

A child stomping around the backyard pretending to be a dinosaur can be enjoying movement and make-believe. We do not need to call it therapy to make room for it.

What This Actually Looks Like on a Wednesday

None of this means you need to enroll your child in six enrichment programs or start building elaborate art stations at 6:45 a.m. (I have tried this. The children were unimpressed.)

What the research supports is more accessible than that.

Keep reading together if you both enjoy it. The Batini study included elementary and middle school pupils. Your older child does not need to outgrow shared stories, but home reading need not become a performance target.

Make room for an absorbing game when you can. A long stretch of stuffed-animal hospital can be worthwhile simply because your child enjoys it. There is no minute-for-minute formula for brain development.

Do not separate movement from creativity. Dance, outdoor imaginative play, and physically expressive dramatic scenarios all count. You do not need an art room or a music teacher. You need some floor space and some tolerance for enthusiastic noise.

Try simple materials. Blocks, playdough, and cardboard boxes can invite invention. This is a practical suggestion, not a claim that a box reproduces the effects of a Montessori classroom.

The Part I Keep Coming Back To

Consider a child with ADHD who finds some structured tasks difficult but becomes absorbed in an imaginative game. That is a useful observation to share with their care team, not proof that ADHD has disappeared or that the game is treating it.

Attention can look different across activities. A compelling story does not tell us, on its own, what will help with schoolwork, daily routines, or another setting.

Pretend play is not a treatment for ADHD. If you are navigating that diagnosis, ask your child's pediatrician or treating clinician how enjoyable activities can fit alongside appropriate support.

There is room for creativity in an ordinary day without turning every game into a brain intervention. The studies discussed here examine different activities, settings, and outcomes; they do not establish a single mechanism that makes pretend play therapeutic. Your child is allowed to play simply because play is worthwhile.

The stuffed giraffe surgery in my living room is, technically, developmentally appropriate.

I'm counting it.
