与非母语相比，双语者能够更好地感知母语中的噪音语音。这种好处被认为是由于更多地使用母语中的更高层次的语言背景。以前的研究表明，这是使用句子，并不允许我们确定哪种语言水平有助于这种背景下的好处。在这里，我们使用了一个新的范例，隔离的语义水平的讲话，在两种语言的双语。结果显示，在母语中，语义相关的目标词有利于感知以前提出的降级总理词相对于当一个语义无关的目标如下总理，这表明语义的具体贡献的母语上下文的好处。我们还发现，在非母语，有一个不利的语义coext的单词识别，这表明这种自上而下的，上下文信息的结果在语义干扰的第二语言。
Bilinguals are better able to perceive speech-in-noise in their native compared to their non-native language. This benefit is thought to be due to greater use of higher-level, linguistic context in the native language. Previous studies showing this have used sentences and do not allow us to determine which level of language contributes to this context benefit. Here, we used a new paradigm that isolates the SEMANTIC level of speech, in both languages of bilinguals. Results revealed that in the native language, a semantically related target word facilitates the perception of a previously presented degraded prime word relative to when a semantically unrelated target follows the prime, suggesting a specific contribution of semantics to the native language context benefit. We also found the reverse in the non-native language, where there was a disadvantage of semantic coext on word recognition, suggesting that such top–down, contextual information results in semantic interference in one’s second language.
