Parent-infant interactions highlight the role of parental input, considering both the quality, infant-directed speech, and quantity of interactions, adult words and communicative turns, in these interactions. However, communication is bidirectional, yet little is known about the infant's role in these interactions. This study (n = 35 4-month-old infants) explores how infant-directed speech, the number of adult words and turn-taking (both measured by the LENA system) are correlated with infants' temperament. Our findings reveal that, while mothers use the typical characteristics of infant-directed speech, they are not correlated with the infant's temperament. However, we observe more adult-infant turn-taking in both introverted infants (with lower Surgency scores) and infants with lower attention regulation (with lower Regulatory/Orienting scores). The number of adult words was not correlated with infants' temperament. We suggest that infants with an introverted temperament prefer quieter exchanges that may lead to more turns and that infants with lower attention regulation might create more opportunities for interactions due to their lower level of self-regulation. These findings suggest that infants' temperament is associated with how adults talk with infants (communicative turns) rather than how adults talk to infants (infant-directed speech, number of adult words). Our results underscore the infant's role in parent-infant communication.
亲子互动凸显了父母投入的作用，这体现在互动的质量（即面向婴儿的言语）以及互动的数量（即成人话语和交流轮次）上。然而，交流是双向的，而对于婴儿在这些互动中的作用却知之甚少。本研究（n = 35名4个月大的婴儿）探讨了面向婴儿的言语、成人话语数量和轮流对话（均通过语言环境分析系统测量）与婴儿气质之间的关联。我们的研究结果表明，虽然母亲使用了面向婴儿言语的典型特征，但这些特征与婴儿的气质并无关联。然而，我们观察到，在性格内向的婴儿（外向性得分较低）和注意力调节能力较低的婴儿（调节/定向得分较低）中，成人与婴儿之间的轮流对话更多。成人话语的数量与婴儿的气质没有关联。我们认为，性格内向的婴儿更喜欢更安静的交流方式，这可能会导致更多的轮流对话，而注意力调节能力较低的婴儿可能由于其较低的自我调节水平而创造更多的互动机会。这些研究结果表明，婴儿的气质与成人和婴儿交谈的方式（交流轮次）有关，而不是与成人对婴儿说话的方式（面向婴儿的言语、成人话语数量）有关。我们的研究结果强调了婴儿在亲子交流中的作用。
