Simultaneous bilingual children sometimes display crosslinguistic influence (CLI), widely attested in the domain of morphosyntax. It remains less clear whether CLI affects bilinguals’ event construal, what motivates its occurrence and directionality, and how developmentally persistent it is. The present study tested predictions generated by the structural overlap hypothesis and the co-activation account in the motion event domain. 96 English–French bilingual children of two age groups and 96 age-matched monolingual English and French controls were asked to describe animated videos displaying voluntary motion events. Semantic encoding in main verbs showed bidirectional CLI. Unidirectional CLI affected French path encoding in the verbal periphery and was predicted by the presence of boundary-crossing, despite the absence of structural overlap. Furthermore, CLI increased developmentally in the French data. It is argued that these findings reflect highly dynamic co-activation patterns sensitive to the requirements of the task and to language-specific challenges in the online production process.

如何（不）跨越边界：同时双语儿童事件解释中的跨语言影响

同时双语的儿童有时会表现出跨语言影响（CLI），这在形态句法领域得到了广泛的证明。尚不清楚 CLI 是否会影响双语者的事件解释，是什么促使其发生和方向性，以及它在发展上的持久性。本研究测试了由结构重叠假设和运动事件域中的共激活帐户生成的预测。两个年龄组的 96 名英法双语儿童和 96 名年龄匹配的单语英语和法语对照被要求描述显示自愿运动事件的动画视频。主要动词中的语义编码显示出双向 CLI。单向 CLI 影响了语言外围的法语路径编码，并且可以通过边界交叉的存在来预测，尽管没有结构重叠。此外，CLI 在法国数据中的发展性增加。有人认为，这些发现反映了对任务要求和在线生产过程中特定于语言的挑战敏感的高度动态的共同激活模式。
