DESCRIPTION (provided by applicant): Bimanual coordination is important to adaptive human functioning; yet our understanding of its development and relation to developmental disorders is incomplete. This project will adopt a dynamic systems approach to examining bimanual competence in children between the ages of 15 and 27 months, a target group whose activity has previously been under-represented in the literature. The project's methodology will include a longitudinal study of an easily elicited rhythmic percussive behavior, drumming. Individual developmental trajectories will be mapped according to the principles and methods of developmental systems analysis. Additionally, introduction of auditory or human models will allow the investigator to determine whether reducing the self-regulatory requirements placed on the child increases the stability of bilateral rhythmic behavior at different points in the development of this skill. It is hypothesized that such reduction of the self-regulatory requirements will indeed increase stability of the drumming behavior at transitional points at which the behavior shifts from one point to another. Kinematic analysis will allow microgenetic as well as ontogenetic data to be reported at both the individual and aggregate level, in keeping with dynamic systems approaches to analysis. It is believed that this project will inaugurate a productive program of study that will allow in-depth examination of the motoric, cognitive, and contextual factors that contribute to bimanual competence in young children, as well as lead to potential early diagnostic and intervention applications for atypical developmental conditions. Additionally, it will provide research-training opportunities for several students who are under-represented minority women. It is important to understand the developmental pathways typically experienced by children with respect to bimanual skills, particularly during the first years of life. Children in this age range are undergoing rapid growth in skill development, and early childhood represents a critical point for diagnosis of developmental disorders prior to entry into school. Because bimanual competence is so integral to our daily activity as humans, and because investigators have discovered links between atypical bimanual coordination patterns and developmental disorders, it is believed that this project may ultimately lead to useful nonlinguistic early diagnostic and intervention tools for children at risk for developmental disorders.

描述（由申请人提供）：双手协调对适应性人类功能很重要;但我们对其发展及其与发育障碍的关系的理解是不完整的。本项目将采用动态系统的方法来研究15至27个月大的儿童的双手能力，这是一个目标群体，其活动在文献中的代表性不足。该项目的方法将包括一个纵向研究的一个很容易引起节奏的跳跃行为，击鼓。根据发展系统分析的原则和方法绘制个人发展轨迹。此外，引入听觉或人类模型将使研究者能够确定是否减少对儿童的自我调节要求，增加双侧节律行为在这种技能发展的不同点的稳定性。据推测，这种自我调节要求的减少确实会增加稳定性的击鼓行为在过渡点的行为从一个点转移到另一个。运动学分析将允许在个体和总体水平上报告微观遗传和个体遗传数据，以符合动态系统分析方法。据信，该项目将开创一个富有成效的研究计划，将允许深入研究有助于幼儿双手能力的运动，认知和背景因素，并导致潜在的早期诊断和干预应用于非典型发育条件。此外，它将为少数民族妇女人数不足的几名学生提供研究培训机会。重要的是要了解儿童在双手操作技能方面通常经历的发展途径，特别是在生命的最初几年。这一年龄段的儿童在技能发展方面正在迅速成长，幼儿期是入学前诊断发育障碍的一个关键点。由于双手能力是我们人类日常活动中不可或缺的一部分，而且研究人员已经发现了非典型双手协调模式与发育障碍之间的联系，因此相信该项目最终可能会为有发育障碍风险的儿童提供有用的非语言早期诊断和干预工具。
