Embodied Attention in Toddlers

描述(申请人提供)：视觉世界杂乱无章，有许多目标和许多令人分心的东西。学习只需要选择和稳定对其中一些信息的关注。这项拟议的研究检验了这样一种观点，即对于蹒跚学步的孩子来说，有效的视觉注意力从根本上说是一个涉及外部身体动作的感觉-运动过程。这项拟议的研究解决了目前对感觉-运动行为如何支持有效的视觉注意的理解上的差距，这是一个关键的差距，因为有证据表明许多发育障碍中存在非典型注意，以及这些发育障碍中非典型感觉-运动模式的共同发病率。拟议的实验测量了多个感觉和运动流：头部和手的运动，眼睛凝视的方向，以及12至24个月大的儿童作用于物体并学习物体时的第一人称头部中心视角。这些研究将详细描述视觉注意的动态，儿童自身的行为如何帮助维持和稳定视觉注意，以及这些过程在学习物体方面的作用。

DESCRIPTION (provided by applicant): The visual world is cluttered with many targets and many distractions. Learning requires selecting and stabilizing attention on just some of that information. The proposed research examines the idea that for toddlers, effective visual attention is fundamentally a sensory-motor process involving external bodily actions. The proposed research addresses a gap in current understanding of how sensory- motor behavior supports effective visual attention, a critical gap given the evidence implicating atypical attention in many developmental disorders and the well established co-morbidity of atypical sensory-motor patterns in these same developmental disorders The proposed experiments measure multiple sensory and motor streams: head and hand movements, eye-gaze direction, and the first- person head-centered view as 12 to 24 month old children act on and learn about objects. The studies will provide a fine-grained description of the dynamics of visual attention, of how children's own actions help to sustain and stabilize visual attention, and the role of these processes in learning about objects.
