A new study found that speech difficulties are linked with difficulties in learning to read when children first start school, but these effects are no longer apparent at 8 years of age.
Researchers confirmed that early language impairment that co-occurs with speech difficulties predicts poor literacy skills at both 5½ and 8 years of age. Having a family history of dyslexia had a small but significant effect on literacy at both ages, above and beyond the effects of speech and language.
"Speech difficulties can be a warning sign, but it is only when a child also has weak language skills that they are likely to lead to significant reading problems, especially if there is a family history of dyslexia," said Dr. Marianna Hayiou-Thomas, lead author of the Journal of Child Psychology and Psychiatry study.
