Participants learned the meaning of novel objects by listening to two complementary definitions while watching videos of the new object, in a single‐language context (all in Spanish) or a mixed‐language context (one definition in Basque, one in Spanish). Then, participants were asked to assess the degree of functional relatedness between novel and familiar objects in two conditions: identical (both definitions overlap) or related (single definition overlap). Relatedness ratings differed significantly between conditions, but they were highly similar across language contexts. Furthermore, items in the identical condition elicited a P300‐like event‐related potential component, while related items elicited a wave of lesser amplitude. Critically, the amplitude differences between conditions did not differ between language contexts. No interaction was found with proficiency level across participants. In line with previous findings, we show no measurable impact of mixing languages during the establishment of a link between novel objects and existing conceptual representations in bilinguals.

流利的巴斯克语-西班牙语双语者在混合语言和单语言上下文中对新对象的相似概念映射

参与者在单语言环境（全部为西班牙语）或混合语言环境（巴斯克语为一种定义，西班牙语为一种）中观看新对象的视频时，通过听两个补充定义来了解新颖对象的含义。然后，要求参与者在以下两种情况下评估新颖对象和熟悉对象之间的功能相关性程度：相同（两个定义重叠）或相关（单个定义重叠）。不同条件之间的相关性评分存在显着差异，但它们在语言环境中非常相似。此外，在相同条件下的物品会引发类似P300的事件相关电位分量，而相关物品会引起较小幅度的波动。至关重要的是，条件之间的幅度差异在语言环境之间没有差异。没有发现参与者之间的熟练程度之间存在互动。与以前的发现一致，我们发现在新颖对象与双语中现有概念表示之间的链接建立过程中，混合语言没有任何可测量的影响。
