噪声环境下的语音理解研究表明，多语言经历可能在过滤言语干扰方面具有优势，这一效应在出生后习得两种或多种语言的儿童（Filippi, Morris, Richardson, a ., 2015）和第二语言学习者成人（Filippi, Leech, Thomas, a ., 2012）中都可以观察到。对这一优势的一种可能的解释是，多语言思维被“训练”来控制非使用语言的干扰。这种持续的努力可能支持对成功选择、处理和解释复杂语言信息所必需的认知资源的优化。本研究旨在通过纳入非言语干扰条件来扩展这一研究路线。209名发育正常的儿童（132名英语单语者和77名来自不同语言背景的多语者）在存在言语和非言语干扰的情况下进行了句子解释任务。在我们的数据中，我们没有发现可靠的群体差异的证据。相反，研究结果表明，背景认知能力和社会经济地位是成功控制干扰的最佳指标，无论参与者是双语还是单语。这些发现是根据以前的研究进行讨论的，更广泛地说，是根据目前关于双语优势的辩论。
Research on speech comprehension in noise indicates that a multilinguistic experience may confer advantages in filtering out verbal interference, an effect observed both in children acquiring two or more languages since birth (Filippi, Morris, Richardson, a al., 2015) and in second language learner adults (Filippi, Leech, Thomas, a al., 2012). A possible interpretation for this advantage is that the multilingual mind is "trained" to control interference from the language not in use. This constant effort may support optimization of cognitive resources that are necessary for successfully selecting, processing and interpreting complex linguistic information. The present study aimed to extend this line of research by including a non-verbal interference condition. 209 typically developing children (132 English monolinguals and 77 multilinguals from different linguistic backgrounds) carried out a sentence interpretation task in the presence of verbal and non-verbal interference. We found no evidence for a reliable group difference in our data. Instead, findings indicated that background cognitive ability and socioeconomic status were the best indicators of successful control of interference, irrespective of whether participants were bilingual or monolingual. These findings are discussed in the light of previous research and, more widely, on the account of the current debate on the bilingual advantage.
