Language gap widens among preschoolers

9 November 2010

A new study shows one in five Australian preschoolers have poor language skills, with those from disadvantaged families the most likely to lag behind their peers.

The study by the Murdoch Childrens Research Institute, Melbourne, found 20 per cent of children had difficulty either using or understanding spoken language at the age of four.

"Children with poor language skills often face serious difficulties at school and it is a concern to see the number of children starting school without the critical skills needed to learn to read and write," co-author Professor Melissa Wake said.

"Language skills are the foundation for achievement throughout the school years and language problems can impact significantly on academic attainment and later employment opportunities."

Children who came from low socio-economic backgrounds, and whose mothers were poorly educated and had low vocabulary levels, were most at risk.

"Social disadvantage did not play a role in predicting language outcomes when these children were toddlers but the gap widened as they reached preschool, possibly through children's cumulative exposure to less-rich language environments," Professor Wake said.

"The findings are concerning but also present an opportunity for intervention during the preschool years. Early interventions should be targeted and aim to enrich the home language environment by encouraging parents to spend time talking and reading to their children. Early referrals to health professionals such as speech pathologists are also vital."

Other risk factors included coming from a non-English speaking background and having a family history of speech and language difficulties. Children who were late talkers at the age of two were more likely to continue experiencing language difficulties at the age of four.

The findings, published online this week by American journal Pediatrics, form part of a longitudinal study of 1900 Victorian children from the age of eight months to help researchers better understand the earliest predictors of language impairment in children. Children are now being followed up at the age of seven.
