• Resumen

  • We conducted a systematic review and meta-analysis on the association between nonword repetition (NWR) and language exposure in bilingual children and explored whether the association is influenced by other variables. We performed a blind literature review on ERIC and Google Scholar, a random-effects model meta-analysis and subgroup analyses to test potential moderators. Out of 822 screened articles, we identified 24 works including 1399 children. Significant associations were found using either cumulative or current exposure, language-like nonwords, phoneme NWR scoring, in children with typical language development. Nonsignificant associations were found in studies either using age of first exposure, on children older than six, with less than 50 participants, using NWR lists containing 16-24 nonwords or with participants having different native languages. Weak associations were found when considering whole-word scoring or gray literature. We highlight the contributions of different variables to NWR, and evidence to optimally design NWR for bilingual language assessment.
