SGER: Self-Produced Locomotion and Perceptual/Emotional Development in Infancy

该项目是一项初步研究，将为一个更大的研究计划奠定基础，该计划涉及婴儿期自我产生的运动对空间，认知和情感发展的作用。 这项研究计划将需要一种“移动装置”（MD），帮助婴儿在成熟之前能够爬行。 初步研究将探索MD的可能设计，并评估婴儿使用这种设备所能达到的熟练程度。 主要目的是（1）量化在MD和随后的爬行中训练的婴儿自发运动的运动熟练度;（2）比较婴儿在需要和不需要肢体运动来推进的设备上的表现;以及（3）获得关于运动能力和运动类型之间关系的初步数据，以及空间，认知，另一方面是情绪的变化。 这项研究的结果，特别是随后的研究计划，应该增加我们对自我产生的运动在婴儿感知和与环境互动的能力发展中所发挥的重要作用的理解。

This project is a preliminary study that will lay the groundwork for a larger research program concerning the role of self-produced locomotion on spatial, cognitive, and emotional development in infancy. The research program will require a `mobility device` (MD) that assists infants in ambulating before they are maturationally able to crawl. The preliminary study will explore possible designs for the MD and assess the level of proficiency infants can attain with such a device. The major objectives are (1) to quantify the locomotor proficiency in the MD and in subsequent crawling of infants trained in self-produced locomotion; (2) to compare infants' performance on devices that do and do not require limb movements for propulsion; and (3) to obtain preliminary data on the relation between locomotor proficiency and type of locomotion on the one hand, and spatial, cognitive, and emotional changes on the other. The results of the study, and especially the subsequent research program, should add to our understanding of the important role played by self-generated movement in development of infants' ability to perceive and interact with their environments.
