THE DEVELOPMENT OF HEADING PERCEPTION IN INFANCYRick O. GilmoreDepartment of PsychologyPennsylvania State UniversityUniversity Park, PA 16802When moving around the environment, animals generate a pattern of visualmotion called optic flow. Optic flow provides information about where andhow fast the observer is moving. This information is crucial for safelymoving through the environment. Despite its importance, very little isknown about how the ability to perceive optic flow develops early in life.This project will examine how young infants develop the ability todetermine which direction they are moving or heading through theenvironment. It will examine the role that changes in visual factors, suchas acuity or sensitivity to motion, play in the ability to perceive one'sheading. The project will examine how infants' emerging abilities to crawland walk shape their perceptual capacities. The project also will examinehow infants develop the ability to use visual information to maintainbalance and control posture. The results will provide new informationabout the development of a perceptual skill that is critical for maintainingbalance, avoiding collisions, and moving safely through the environment.In turn, the results will lay the groundwork for future research into theimpact of postnatal brain development on other aspects of perceptual andmotor development. Finally, this CAREER project will incorporate educationalactivities that will help to train a new generation of students in theemerging field of developmental

婴儿头部知觉的发展。Gilmore宾夕法尼亚州立大学心理学系University Park，PA 16802当动物在环境中移动时，会产生一种称为光流的视觉运动模式。 光流提供了观察者移动的位置和速度的信息。 这些信息对于在环境中安全移动至关重要。 尽管它很重要，但人们对感知光流的能力在生命早期是如何发展的知之甚少。本项目将研究幼儿是如何发展判断他们在环境中移动或前进方向的能力的。 它将研究视觉因素的变化，如敏锐度或对运动的敏感度，在感知一个人的头部能力中所起的作用。 该项目将研究婴儿爬行行走的新兴能力如何塑造他们的感知能力。 该项目还将研究婴儿如何发展利用视觉信息来保持平衡和控制姿势的能力。 这些结果将为感知技能的发展提供新的信息，感知技能对于保持平衡、避免碰撞以及在环境中安全移动至关重要。反过来，这些结果将为未来研究出生后大脑发育对感知和运动发育的其他方面的影响奠定基础。 最后，这个职业生涯项目将纳入教育活动，这将有助于培养新一代的学生在新兴领域的发展
