Sensorimotor Dynamics of Parent-Child Interactions Build Word Learning Skills

描述(申请人提供)：日常社交活动，如与父母玩耍，是学习的环境，因为它是实时展开的。协调良好的儿童保育员 互动似乎可能带来更好的学习，而脱钩或不协调的互动可能会扰乱学习和发展。父母和孩子都在早期交流和单词学习中发挥着积极的作用，因为孩子们向他们的交流选择发出信号，并决定什么环境信息与他们自己的发展需要最相关，父母以敏感的方式对这些信号做出反应，并提供相关信息，以缓解儿童将语言符号与其所指对象匹配的挑战。这项研究的目的是为了更深入地了解早期社会协调的感觉运动基础，以及它在后来的语言学习和其他发展里程碑中的潜在关键作用。为了实现这一目标，本研究有三个关键部分：1)一组纵向和横断面实验将从儿童-父母玩具游戏中收集多个感觉运动数据，以发现儿童-父母社交互动早期发展变化的细粒度模式，这将为这些技能的发展起源提供新的证据；2)我们将儿童-父母互动中的感觉-运动动态与广泛使用的标准化、高度可靠的行为测量相联系，目的是了解儿童与社会伙伴的时时刻刻的社交互动如何建立普遍的词汇学习技能；3)我们将玩具游戏中的社会协调与父母的反应和个体在发展里程碑上的差异联系起来，这将为早期亲子互动在发展过程中的结果和长期作用提供更深入的见解。

DESCRIPTION (provided by applicant): Everyday social activities such as toy play with parents are the context for learning as it unfolds in real time. A well coordinated child-caregiver interaction seems likely to lead to better learning while a decoupled or non-coordinated interaction may disrupt learning and development. Both parent and child play an active role in early communication and word learning as children "signals" their choices of communication and also determine what environmental information is most relevant to their own developmental needs, and as parents react to those signals in a sensitive manner and provide relevant information to ease the challenge of children's matching linguistic symbols to their referents. The goal of the proposed research is to achieve a deeper understanding of the sensorimotor basis of early social coordination and its potentially critical roles in later language learning an other development milestones. Toward this goal, the proposed research has three key components: 1) a set of longitudinal and cross-sectional experiments will collect multiple streams of sensorimotor data from child-parent toy play to discover fine-grained patterns characteristic of early developmental changes in child-parent social interactions which will provide new evidence on the developmental origins of these skills; 2) we will link sensorimotor dynamics in child-parent interaction with standardized, highly reliable behavioral measures that have been widely used, with the goal to understand how children's moment-to-moment social interactions with social partners may build generalizable word learning skills; 3) we will link social coordination in toy play with parental responsiveness and individual differences in development milestones, which will provide deeper insights into the consequential and longer-term role of early parent-child interactions in developmental process.
