Embodied Attention in Toddlers

描述（由申请人提供）：视觉世界是混乱的许多目标和许多分心。学习需要选择并稳定对其中一些信息的注意力。这项拟议中的研究检验了这样一种观点，即对于幼儿来说，有效的视觉注意力从根本上说是一种涉及外部身体动作的感觉运动过程。拟议的研究解决了目前对感觉运动行为如何支持有效视觉注意力的理解中的差距，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力，并且在这些相同的发育障碍中存在非典型感觉运动模式的共同发病率。拟议的实验测量多个感觉和运动流：头和手的运动，眼睛注视方向，以及第一人称的以头为中心的视图，因为12到24个月大的儿童对物体进行动作和学习。这些研究将对视觉注意力的动态、儿童自身的行为如何帮助维持和稳定视觉注意力以及这些过程在学习物体中的作用进行精细描述。

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.
