Exploring language learning and early childhood education through research
It's Not Just Playing — Kids Have to Imagine the Impossible to Grow Their Minds
Not all play is equal. A randomized experiment with 110 preschoolers found that only fantastical pretend-play—dragons, trips to the moon—improved executive function, while ordinary play did not.
Can I Just Let My Kid Play Outside Instead of Studying? What 10,000 Children Suggest
Outdoor play can feel like the opposite of getting ready for school. A 2024 study of 10,682 preschoolers points the other way—though how you read it matters.
Will an Only Child Struggle to Read Others' Minds? Two Twists in the Research on Siblings and Mind-Reading
A study of 109 children aged 3–6 in Wuhan, China found that only first-borns — not all children with siblings — outperformed only-children on theory of mind. And the only-child gap closed after just two weeks of a short language-based intervention, suggesting it was never a fixed limitation.
What Your Hands Do During Read-Alouds May Shape Your Child's Vocabulary
Researchers observed 33 Head Start classrooms and coded the gestures teachers made while reading picture books to 306 four-year-olds. Classrooms where teachers used more meaning-focused gestures — like spreading their arms wide on “huge” — had children with higher end-of-year receptive vocabulary. The hand may open a second channel for kids who can’t yet catch every word.
"My Child Is the Only One Whose Speech Is Late" — A 17-Year Follow-Up of Those Children
Leslie Rescorla followed 26 children who were late talkers at age 2 all the way to age 17. Every one of them ended up in the average range for adolescent language and reading — though they sat slightly below their same-SES peers who had not been late.
Two Faces of a Child Who Controls a Parent — The One Who Commands, the One Who Caretakes
A Canadian study of 242 children compared two faces of “controlling attachment” — the demanding child and the caretaking child. Same root, different branches. The caretaking children had more internalizing problems and more loss in their family histories.
For an Anxious Child, Soothing Isn't the Answer — Training Only the Parents for 12 Weeks Matched CBT
A Yale RCT randomized 124 anxious children to either standard child-only CBT or a parent-only program (SPACE). After 12 weeks, training only the parents — without the child ever entering therapy — produced equivalent reductions in child anxiety.
Mothers and Fathers Talk About the Same Amount — but the Words Children Hear Are Different
Trinity College Dublin researchers analyzed 84 toddlers playing one-on-one with each parent. Mothers and fathers produced similar quantity and complexity of speech — but used different word sets, exposing children to a partly overlapping, partly different vocabulary menu.
The Age When Parents Want to Drop the Nap Is Exactly When the Nap Helps Most
A 2025 meta-analysis pooling 27 studies and 67 effect sizes found that naps boost declarative memory in early childhood — and the effect size is largest, surprisingly, in 3- to 5-year-olds, exactly the age when parents most often consider dropping the nap.
Four Sessions of a Board Game Reshaped Low-Income Preschoolers' Sense of Number
A simple linear-number board game played four times — about an hour total — produced large, durable gains across four numerical tasks for low-income preschoolers. A near-identical color version produced no change. The structure of the game, not the play, was the active ingredient.
