在双语者母语不同的地区，评估双语儿童的语言发展是具有挑战性的。词汇发展量表常被用作研究双语儿童语言能力的起点。人们发现，非单词重复(NWR)在检测变异方面具有很大的信息量。本研究有助于更广泛的研究目标，记录双语者的语言技能。在19名母语不同的讲意大利语的双语儿童中，计算了在类意大利语NWR上的表现与接受性词汇得分(意大利语pPVT-R)、累计接触意大利语、首次接触意大利语的年龄、当前意大利语接触、母亲教育、父母关心的问题和幼儿时期词汇(MB-CDI)之间的相关性。NWR的表现与pPVT-R和父母的担忧有关，但与母亲的教育和语言暴露措施无关。NWR得分和pPVT-R得分与幼儿时期意大利语词汇量(MB-CDI)均无相关性。我们将我们的研究结果与其他人的研究结果结合起来，讨论了对双语儿童实施NWR的利弊，以及更广泛地说，如何进行早期的双语语言评估。
Assessing language development in bilingual children is challenging in geographical areas where bilinguals have different native languages. Lexical development measures are often used as a starting point to study linguistic abilities in bilingual children. Non-word repetition (NWR) has been found to be very informative in detecting variation. The present study contributes to the broader research aim of documenting bilinguals' language skills. In a sample of 19 Italian-speaking bilingual children with different native languages, correlations among performance on an Italian-like NWR and receptive vocabulary score (Italian PPVT-R), cumulative exposure, age of first exposure to Italian, current Italian exposure, maternal education, parental concerns and vocabulary in toddlerhood (MB-CDI) were calculated. NWR performances correlated with PPVT-R and parental concerns, but not with maternal education and language exposure measures. Neither NWR scores nor PPVT-R scores were related to Italian vocabulary size in toddlerhood (MB-CDI). We integrate our results with those of others and discuss the advantages and disadvantages of administering NWR to bilingual children, and more generally how to perform early bilingual language assessments.
