Abstract

Abstract In motor skill performance and retention the complexity of knowledge of results should interact with the child's processing rate. This rate has been demonstrated to increase with age. Two experiments were designed to assess this hypothesis. In Experiment 1, 30 7-year-old and 30 10-year-old boys were randomly assigned within age level to three knowledge of results (KR) conditions: no KR, general KR, and precise KR. Performance was assessed on a vertical positioning task at two angles, 60° and 100°, for 10 performance trials. The preciseness of KR interacted with age and the degree of the angle, indicating that at the more difficult angle (60°) preciseness may have been detrimental to the performance of the 7-year-olds but beneficial to the 10-year-olds. At the easier angle (100°), precise KR improved performance for both age groups. In Experiment 2, 27 second-grade and 27 fourth-grade children were randomly assigned within age groups to the same three levels of KR preciseness. A horizontal curvili...

结果的精确知识和运动表现:与年龄的关系

在运动技能表现和记忆中，知识结果的复杂性与儿童的加工速度有关。这一比率已被证明随着年龄的增长而增加。设计了两个实验来评估这一假设。在实验1中，30名7岁和30名10岁的男孩被随机分配到三种结果知识(KR)条件下:无KR、一般KR和精确KR。在10个表现试验中，评估了在60°和100°两个角度的垂直定位任务中的表现。KR的精确度与年龄和角度的程度相互作用，表明在难度较大的角度(60°)下，精确度可能对7岁儿童的表现不利，而对10岁儿童的表现有利。在更容易的角度(100°)，精确的KR提高了两个年龄组的表现。在实验2中，27名二年级和27名四年级儿童被随机分配到相同的三个KR精确度水平的年龄组中。一条水平曲线……
