Parents modulate their speech and their actions during infant-directed interactions, and these modulations facilitate infants' language and action learning, respectively. But do these behaviors and their benefits cross these modality boundaries? We investigated mothers' infant-directed speech and actions while they demonstrated the action-effects of 4 novel objects to their 14-month-old infants. Mothers ( = 35) spent the majority of the time either speaking or demonstrating the to-be-learned actions to their infant while hardly talking and acting at the same time. Moreover, mothers' infant-directed speech predicted infants' action learning success beyond the effect of infant-directed actions. Thus, mothers' speech modulations during naturalistic interactions do more than support infants' language learning; they also facilitate infants' action learning, presumably by directing and maintaining infants' attention toward the to-be learned actions.

父母在与婴儿互动时会调整他们的语言和行为，这些调整分别促进了婴儿的语言和行为学习。但是这些行为及其益处是否会跨越这些模式的界限呢？我们观察了母亲在向 14 个月大的婴儿展示 4 种新物体的动作效果时，对婴儿的指令性言语和动作。母亲（=35）大部分时间都在对婴儿说话或演示要学习的动作，几乎不在同一时间说话和动作。此外，母亲对婴儿的指令性言语对婴儿的动作学习成功的预测作用超过了对婴儿指令性动作的预测作用。因此，母亲在自然互动中调整言语不仅有助于婴儿的语言学习；它们还促进了婴儿的动作学习，可能是通过引导和保持婴儿对要学习的动作的注意力。（心理学信息数据库记录（c）2020 APA，保留所有权利）。
