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）：本提案中提出的问题代表了一种思考婴儿期运动转换的新方法。这些实验不是关注婴儿如何应对开始接触事物所固有的复杂的身体任务，而是探索他们这样做的原因：首先是什么吸引婴儿对物体采取行动？我研究了三种可能的动机来源：对象驱动、他人驱动和自我驱动。实验调查了所有三个来源的影响，并进一步研究了自我驱动因素的作用，假设婴儿自己对物体的行为（首先是意外产生的物体，后来是有意产生的物体）的反馈对于在适当的时间过渡到触及至关重要。这种反馈具有强化作用，有助于吸引婴儿与物体进行更多互动。测试该模型需要使用粘性手套，这是 P.I. 发明的一种装置。研究婴儿期到伸手的过渡。总体而言，该提案在运动发育研究方面开辟了新天地，并提供了一个新的视角，研究人员可以通过该视角了解婴儿期的运动转变。它还将提供明确的干预计划，帮助有视觉或运动障碍的婴儿比其他情况更早地开始接触物体。公共健康相关性：拟议的研究通过测试三种可能的想法来调查婴儿为什么开始伸手去拿物体的问题：婴儿对物体感到好奇，他们想模仿其他人，和/或他们从自己行为的后果中学习。如果我们了解是什么促使正常发育的婴儿伸手去拿物体，我们就可以设计干预措施来帮助非典型发育的婴儿比其他情况更早地开始伸手。婴儿越早对物体产生兴趣并开始自己伸手去拿物体，他们对物质世界的了解就越多。
