The Talking Cure: Why Early Language is the Most Urgent Issue in Early Years Today

The BERCOW Review, the 30 million word gap, and what every practitioner can do tomorrow

In 1995, two researchers at the University of Kansas published a study that would change how we think about early language development. Betty Hart and Todd Risley had spent years recording every word spoken to children in 42 families across different socioeconomic groups. What they found was staggering.

By age three, children from professional families had heard approximately 30 million more words than children from families on welfare. — Hart & Risley (1995)

Thirty million words. Not a small difference in input, but a chasm. And that gap, they found, predicted language skills, academic achievement and life outcomes in ways that persisted for years.

The BERCOW Review: A Sector in Crisis

BERCOW: Ten Years On (2018) The original BERCOW Review (2008) identified speech, language and communication needs (SLCN) as the most common form of special educational need in children. The ten-year follow-up found that the situation had worsened. More than 1 million children in England have SLCN. Early identification and intervention remain inadequate. And the children most likely to be affected are those from disadvantaged backgrounds — the very children for whom early years settings are most important. Bercow, J. (2018). Bercow: Ten Years On. Royal College of Speech and Language Therapists.

What the Research Tells Us About Language-Rich Environments

The good news — and there is good news — is that the research is equally clear about what makes a difference. Language development is not primarily genetic or fixed. It is profoundly influenced by the quality of the language environment a child inhabits.

Quantity and Quality of Talk (Weisleder & Fernald, 2013) Weisleder and Fernald found that it was not just the quantity of words children heard that predicted language development, but the quality of conversational interactions — specifically, child-directed speech in which the adult responded contingently to the child's own communication attempts. A child who is talked with — not just talked at — develops language significantly faster than a child who is merely exposed to language. Weisleder, A. & Fernald, A. (2013). Talking to Children Matters. Psychological Science, 24(11), 2143–2152.

Five Ways to Build a Talk-Rich Environment

•        Narrate everything — describe what you are doing, what the child is doing, what you can see, hear and smell. Use rich, varied vocabulary.

•        Follow the child's lead — respond to what the child is communicating, even if it is non-verbal. Expand their utterances: if they say 'dog', you say 'yes, a big brown dog'.

•        Pause and wait — give children time to respond. The research suggests practitioners often fill silences too quickly, depriving children of processing time.

•        Read together every day — not just the words on the page but the conversation around the book. Dialogic reading (Zevenbergen & Whitehurst, 2003) produces significantly greater language gains than simply reading aloud.

•        Audit your environment — are there quiet spaces where children can have one-to-one conversations? Or is the setting too noisy for language to flourish?

A Note on Disadvantage

The language gap is not inevitable. Research from settings that serve disadvantaged communities consistently shows that high-quality adult-child interaction can close, or significantly narrow, the gap. This is one of the most powerful things early years practitioners do. Not the resources, not the curriculum, not the paperwork. The conversation. The relationship. The words.

You are, quite literally, building children's brains with every interaction. That is not a metaphor. It is neuroscience.
