In this article we report patterns of task-to-task vagal tone change across multiple language and play tasks as well as associations between these patterns of task-to-task vagal tone change and language and play performance in 20-month-old girls and boys. Although initially different in vagal tone suppression during solitary play, girls and boys exhibited similar group patterns of vagal reengagement during successive language and play tasks with their mothers and with an experimenter. In terms of individual differences, vagal suppression during solitary play and vagal reengagement during social interactive tasks predicted language and play performance. Gender differences emerged in patterns of predictive relations: Task-to-task vagal changes predicted primarily play performance in girls and language performance in boys. These findings expose the effects of social context on directional changes in task-to-task vagal tone and speak to the functional role of appropriate vagal regulation in young children's language and play performance.
在本文中，我们报告了20个月大的女孩和男孩在多种语言和游戏任务中任务间迷走神经张力变化的模式，以及这些任务间迷走神经张力变化模式与语言和游戏表现之间的关联。尽管在独自玩耍时迷走神经张力抑制最初有所不同，但在与母亲和实验者进行的连续语言和游戏任务中，女孩和男孩表现出相似的迷走神经重新参与的群体模式。就个体差异而言，独自玩耍时的迷走神经抑制和社交互动任务中的迷走神经重新参与预测了语言和游戏表现。预测关系模式中出现了性别差异：任务间迷走神经变化主要预测女孩的游戏表现和男孩的语言表现。这些发现揭示了社会背景对任务间迷走神经张力方向变化的影响，并说明了适当的迷走神经调节在幼儿语言和游戏表现中的功能作用。
