The association of cognitive abilities with language disorder in 8-year-old children: A population-based clinical sample.

Background: Despite accumulated evidence that language development depends on basic cognitive processes, the balance in contributions of verbal and non-verbal cognitive skills to language abilities is still underexplored. Little is known about which cognitive measures best predict the degree of severity in children with language disorder (LD).

Aims: To examine the association between verbal and non-verbal cognitive abilities with language abilities in typically developing and language impaired 8-year-old children, as well as which cognitive abilities are most effective in distinguishing LD severity levels.

Preschool Speech Intelligibility and 8-Year Literacy: A Moderated Mediation Analysis.

Purpose The aims of this study were (a) to examine the relationship between speech intelligibility at the age of 5 years and literacy skills at the age of 8 years, (b) to explore the possible mediating or moderating role of broader language skills at 5 years in the relationship of interest, and (c) to assess whether the potential risk factors (child gender; maternal education levels; and family history of speech, language, reading, and writing difficulties) influence the relationship between speech intelligibility and literacy in terms of moderated mediation effects. Method We used mother-reported questionnaire data on 16,184 children participating in the population-based, prospective Norwegian Mother, Father and Child Cohort Study as well as conducted linear regression analyses using the PROCESS macro in SPSS. In addition, logistic regression was conducted to make predictions about risk.

Predicting Literacy Skills at 8 Years From Preschool Language Trajectories: A Population-Based Cohort Study.

Purpose This article explored the predictive values of three main language delay (LD) trajectories (i.e., persistent, late onset, and transient) across 3-5 years on poor literacy at 8 years.
