项目摘要

DESCRIPTION (provided by applicant): The questions asked in this proposal represent a new way of thinking about motor transitions in infancy. Rather than focusing on how infants navigate the complicated physical tasks inherent to beginning to reach, these experiments explore why they do so: what entices infants to act on objects in the first place? I examine three possible sources of motivation: Object-driven, Other-driven, and Self-driven. Experiments investigate the influence of all three sources and go on to further investigate the role of self-driven factors, hypothesizing that feedback from infants' own actions on objects (first those produced accidentally, later those produced intentionally) is critically important for making the transition into reaching at the appropriate time. This feedback is reinforcing and helps draw infants into more interactions with objects. Testing this model involves the use of sticky mittens, a device invented by the P.I. to study the transition into reaching during infancy. Overall, this proposal breaks new ground in motor development research and offers a new lens through which researchers can understand motor transitions in infancy. It also will provide clear-cut plans for interventions that could help infants with visual or motor impairments begin reaching for objects earlier than they would otherwise. PUBLIC HEALTH RELEVANCE: The proposed research investigates the question of why infants begin reaching for objects by testing three possible ideas: infants are curious about objects, they want to imitate other people, and/or they learn from the consequences of their own actions. If we understand what motivates typically developing infants to reach for objects, we can design interventions to help atypically developing infants begin to reach earlier than they would otherwise. The earlier infants become interested in and begin reaching for objects on their own, the more they can learn about the physical world.

描述（由申请人提供）：此提案中提出的问题代表了一种关于婴儿期运动过渡的新方式。这些实验并没有专注于婴儿如何导航复杂的物理任务，而是探讨了为什么这样做：是什么诱使婴儿首先对物体作用？我检查了三种可能的动机来源：对象驱动，其他驱动和自动驱动。实验研究了所有三种来源的影响，并继续进一步研究自我驱动因素的作用，假设婴儿自己对物体的行为的反馈（首先是偶然产生的对象，后来有意产生的物体）对于使过渡到适当的时间至关重要。这种反馈正在加强，并有助于吸引婴儿与对象的更多相互作用。测试此模型涉及使用P.I.发明的粘性手套。研究婴儿期到达的过渡。总体而言，该建议在运动开发研究中打破了新的基础，并提供了一种新的镜头，研究人员可以通过该镜头了解婴儿期的运动过渡。它还将为干预措施提供明确的计划，这些计划可以帮助您的视觉障碍或运动障碍的婴儿早于其他时间就开始遇到物体。公共卫生相关性：拟议的研究调查了为什么婴儿通过测试三个可能的想法开始到达对象的问题：婴儿对物体感到好奇，他们想模仿他人，和/或他们从自己的行为的后果中学习。如果我们了解什么是什么促使通常发育婴儿到达物体的原因，我们可以设计干预措施，以帮助非典型发育的婴儿开始比以前更早地触及。较早的婴儿对自己感兴趣，并开始独自抓住物体，他们就越能了解物理世界。
