Development of Anticipatory Orienting Strategies During Locomotor Tasks in Children

摘要: Abstract GRASSO, R., C. ASSAIANTE, P. PREVOST AND A. BERTHOZ. Development of anticipatory orienting strategies during locomotor tasks in children. NEUROSCI BIOBEHAV REV 22 (4) 533–539, 1998.—Some basic problems related to the development goal-directed locomotion humans are reviewed here. A preliminary study is presented which was aimed at investigating emergence head Eight children ranging from 3.5 8 years had walk along a 90° right corner trajectory reach goal, both light and darkness. The instantaneous orientation space head, trunk, hips left foot antero/posterior axes computed by means an ELITE four-TV camera, 100 Hz system. results showed that predictive movements can occur also youngest starts rotate toward goal before point reached. In children, peak rotation coincides with while adults attained before. walking speed largely decreased suggest feedforward control appears very early gait becomes increasingly important afterwards.
