Child Cognitive Development
How Imagination Supports a Child’s Development (What Science Really Says)

Quick answer: Imagination helps a child’s development by letting them picture things that aren’t in front of them: a new idea, another person’s feelings, or “what would happen if.” That one skill feeds problem solving, language, planning, and empathy. Pretend play, stories, and imaginary friends are the everyday ways kids exercise it.
Key Takeaways
- Imagination isn’t just fantasy. It’s a thinking tool kids use to plan, solve problems, and understand others.
- 65% of children up to age 7 have had an imaginary friend. It’s normal and often healthy.
- In one study, a 5-week pretend-play program boosted preschoolers’ executive function.
- Pretending to be a hero helped young kids stick with a boring task longer.
- Honest note: research says pretend play is one good route to growth, not the only one.

What is imagination in child development?
Imagination is the ability to make pictures and ideas in your mind that aren’t right there in front of you. For kids, it means a stick becomes a sword, a box becomes a spaceship, and “what if?” becomes a game.
That might sound like pure fun. It is fun. But it’s also serious brain work.
When your child pretends a block is a phone, they’re holding two ideas at once: “this is a block” and “this is a phone.” That’s called symbolic thinking. It’s the same skill they’ll later use to understand that letters stand for sounds and numbers stand for amounts. It’s a big part of cognitive development, the growth of how kids think.
How does imagination support cognitive development?
Imagination supports cognitive development by letting kids test ideas in their heads before trying them for real. It builds problem solving, planning, language, and the ability to see things from someone else’s view.
- Problem solving: “If the bridge falls, how could we make it stronger?” Kids picture fixes before they try them.
- Planning and self-control: Pretend games have roles and rules. “You’re the shopkeeper, so you have to wait for me to pay.”
- Language: Kids narrate, bargain, and tell stories while they pretend.
- Empathy: Playing “doctor” or “mom” means stepping into someone else’s shoes.
- Flexible thinking: When the story changes, kids have to change with it.

Does pretend play really make kids smarter?
Pretend play helps, but the honest answer is that research hasn’t proven it’s the only or most important path. It’s one strong route among several, like reading, talking, and other kinds of play.
I want to be straight with you here, because a lot of articles overstate it. A big 2013 review by Angeline Lillard and colleagues looked at decades of studies. Their take-away: the evidence doesn’t support strong claims that pretend play is uniquely crucial. For some skills, like reasoning, pretend play seems to be one of many routes that lead to the same place. The authors called for more and better research.
So what does the newer research show? Some encouraging results:
Pretend play and executive function
In a 2016 study by Thibodeau and colleagues, 110 children aged 3 to 5 were randomly put into three groups. One group did a 5-week fantastical pretend-play program. One did play that wasn’t imaginative. One did their usual routine. Only the pretend-play group improved in executive functions, the brain’s “management” skills. The kids who got most into the fantasy gained the most.
The “Batman effect”
This one makes me smile. In a 2017 study in Child Development, 180 children aged 4 and 6 were asked to do a dull task for 10 minutes, with a fun video game close by as a temptation. Kids who pretended to be a character, like Batman, spent the most time on the task.
“When your child says ‘I’m a superhero,’ they may be borrowing that hero’s strength to do hard things.”
| What research suggests | What’s still unclear |
|---|---|
| Fantasy play can boost executive function in preschoolers (Thibodeau, 2016). | Whether pretend play is better than other good activities. |
| Pretending to be a hero can help kids keep going (White, 2017). | How long these effects last. |
| Imaginary friends are common and linked to social understanding (Taylor, 2004). | Whether imaginary friends cause better social skills. |
| Pretend play is one of many routes to good reasoning (Lillard, 2013). | Pretend play’s exact role in creativity and IQ. |
Pro Tip: Facing a tough task like cleaning up? Ask, “What would a superhero do right now?” or “Can Captain Tidy help?” Borrowing a character can make hard jobs easier for little ones.
Are imaginary friends normal?
Yes, imaginary friends are very normal. Most kids have one at some point, and they’re often linked with good social understanding.
A study by Marjorie Taylor and colleagues (2004) followed children from preschool into school age. It found that 65% of children up to age 7 had an imaginary companion at some point. School-age kids played with imaginary friends and pretended to be characters just as much as preschoolers did. And kids who didn’t pretend to be characters scored lower on understanding emotions.
So if your child sets a place at the table for “Mr. Tiggles,” relax. You can even ask Mr. Tiggles how his day was.

How does imagination change as kids grow?
Imagination starts with simple pretend in toddlers, blooms into rich make-believe in the preschool years, and turns into stories, inventions, and “what if” thinking in school-age kids.
| Age | How imagination shows up | How to feed it |
|---|---|---|
| Toddlers (1 to 3) | Copying you: “talking” on a toy phone, feeding a doll. | Join in. “Is baby hungry? What should we cook?” |
| Preschoolers (3 to 5) | Dress-up, playing roles, imaginary friends, made-up stories. | A dress-up box, puppets, and “and then what happened?” |
| School-age (6 to 12) | Made-up worlds, comics, building inventions, “what if” questions. | Notebooks, building kits, storytelling games, plays. |

Is my child lying or just imagining?
Young kids often mix make-believe and real life, and that’s usually imagination, not lying. In play, the line between pretend and real is part of the fun.
If your 4-year-old says a dragon spilled the juice, try this: smile, and say, “Wow, that dragon made a mess! Let’s clean it up together.” You keep the story alive and still teach responsibility. Save serious talks about truth for when it really matters, and keep them calm.
How can parents encourage imagination at home?
You encourage imagination by giving kids open-ended stuff, unhurried time, and a willing play partner. Here are 7 easy ways.
- Keep a dress-up box. Old hats, scarves, bags, and shoes are enough.
- Save the cardboard boxes. A big box can be a car, a castle, or a rocket in the same afternoon.
- Tell “pass-along” stories. You say one sentence, your child says the next. See where it goes.
- Ask “what if” questions. “What if dogs could talk? What would ours say?”
- Read, then change the ending. “What if the wolf was nice?”
- Play the role you’re given. If you’re told to be the baby dragon, be the best baby dragon ever.
- Let boredom happen. Empty time is where imagination fills in the gaps.
When kids imagine fixes to pretend problems, they’re practicing real problem solving. Our guide on how children develop problem-solving skills shows how that grows.
Pro Tip: Don’t direct the pretend game. Ask questions instead: “Where is our ship going?” “Who lives on that planet?” Your child does the imagining. You just keep the door open.
Do autistic children have imagination?
Yes. The old idea that autistic children “lack imagination” isn’t accurate. Many autistic kids have rich inner worlds, though their pretend play may look different or be less social.
A 2023 study by Davis and colleagues in the journal Autism asked parents of autistic children aged 5 to 12 about imaginary friends. Almost half said their child had one. Autistic kids with imaginary friends showed a better understanding of others’ minds and stronger social skills than those without. The researchers concluded that, when it comes to imaginary friends, autistic children’s play is similar to other children’s.
Your child may pretend through a favorite topic, through lining up a world of toy animals, or through drawing and building rather than role-play. Follow their lead and join in the way they like to play.

A gentle note: This article isn’t meant to diagnose anything. Every child imagines in their own way and at their own pace. If your child shows little or no pretend play compared with other kids their age, seems confused about what’s real in a way that scares or upsets them, or you have other worries about their development, talk with your pediatrician or a child psychologist.
FAQ: Imagination and cognitive development
Q: At what age do kids have an imagination?
A: Simple pretend, like feeding a doll or talking on a toy phone, often shows up in the toddler years. Imagination really blossoms between about ages 3 and 5, and it keeps growing through school age.
Q: Does imagination increase IQ?
A: There’s no solid proof that imagination raises IQ. A major 2013 review found the evidence on pretend play and intelligence inconsistent. Imagination does help with skills like planning, self-control, and understanding others.
Q: What are the four types of imagination?
A: There’s no single, agreed-on list of four types. For parents, it’s more useful to think about how kids imagine: pretend play, storytelling, imaginary friends, and inventing or building new things.
Q: Are imaginary friends a sign of a problem?
A: Usually not. About 65% of children up to age 7 have had one. They’re common, normal, and often linked with good social understanding.
Q: What is the relationship between imagination and cognitive development?
A: Imagination is a thinking skill. It lets kids hold ideas in mind, test “what if,” and see other points of view, which all feed problem solving, language, and reasoning.
The bottom line
When your child turns the couch into a pirate ship, they’re doing real mental work: planning, talking, solving problems, and stepping into other shoes. Give them boxes, time, and a willing crew member. That’s you.
Imagination is just one piece of the thinking puzzle. See how it fits with memory, language, and attention in our guide to the main areas of cognitive development.
