The current study explored bilingual parent and child code-switching patterns over time. Concurrent and predictive models of code-switching behaviour on executive function outcomes were also examined in a sample of 29 French-English bilinguals at 36 (Wave 1) and 61 (Wave 2) months of age. We investigated whether code-switching typology in a single-language context predicted executive function performance at each wave independently, and whether growth in code-switching frequency across waves predicted executive function performance at Wave 2. At both waves, parents and children participated in two free play sessions (in English and French), followed by a battery of executive function tasks administered in the dominant language. Results indicate more frequent code-switching from the non-dominant to the dominant language in children, and that children code-switch to fill lexical gaps. Results also suggest that less frequent code-switching in a single-language context is associated with better inhibitory control skills during the preschool period.
本研究探讨了双语家长与孩子随时间变化的语码转换模式。同时，还在一个由29名36个月（第1波）和61个月（第2波）大的法英双语儿童组成的样本中，考察了语码转换行为对执行功能结果的共时模型和预测模型。我们研究了在单一语言环境中的语码转换类型是否能独立预测每一波的执行功能表现，以及跨波次语码转换频率的增长是否能预测第2波的执行功能表现。在两个波次中，家长和孩子都参与了两场自由玩耍环节（分别用英语和法语），随后是一系列用优势语言进行的执行功能任务。结果表明，儿童从非优势语言到优势语言的语码转换更频繁，并且儿童进行语码转换是为了填补词汇空白。结果还表明，在单一语言环境中语码转换频率较低与学龄前更好的抑制控制能力相关。
