Visual, manual, and postural coordination in the development of prehension

Using a dynamic reaching paradigm and recording technologies, the aim of this study is to describe the real-time cascade of postural, exploratory, and performatory movements that comprise typical manual actions, and to understand how these sequential and simultaneous components unfold over development. The study uses computerized video analysis, head-mounted eye tracking, high resolution motion tracking, and a motorized chair apparatus to study how infants coordinate body posture, eye movements and performatory reach-to-grasp movements under various conditions of ongoing movement. Infant data are compared to a sample of healthy young adults.
