The children's test of nonword repetition: A test of phonological working memory

TLDR

The Children's Test of Nonword Repetition (CNRep) is a measure of phonological working memory. The study examines the psychological mechanisms linking nonword repetition to language development. Normative data for over 600 children aged 4–9 show that CNRep scores are strongly and specifically related to vocabulary, reading, and comprehensive language skills, outperforming auditory digit span as a predictor.

Abstract

Abstract This article presents findings from the Children's Test of Nonword Repetition (CNRep). Normative data based on its administration to over 600 children aged between four and nine years are reported. Close developmental links are established between CNRep scores and vocabulary, reading, and comprehensive skills in children during the early school years. The links between nonword repetition and language skills are shown to be consistently higher and more specific than those obtained between language skills and another simple verbal task with a significant phonological memory component, auditory digit span. The psychological mechanisms underpinning these distinctive developmental relationships between nonword repetition and language development are considered.
