儿童对物体运动速度的认知发展——4—10岁儿童比较匀速直线运动物体速度的实验(上)

THE DEVELOPMENT OF CHILDREN'S COGNITION OF VELOCITY OF MOVING OBJECTS(Ⅰ)

本研究的目的是探讨不同年龄儿重速度认知发展的水平和特点。被试为4—10岁儿童共140人。采用个别实验。主试让儿童比较等速匀速运动中四种不同实验条件下两个玩具汽车行驶的速度。每做完一个项目后,不管儿童回答是否正确都要求儿童说明理由。本文仅报告实验的一部分结果。部分实验结果表明:本研究的各个项目所测得的儿童能力彼此有一定程度的内部的一致性;同一儿童的许多反应之间大多是有一定的一致性的。

The purpose of this study is to explore the levels and characteristicsof the development of children’s cognition of velocity at different ages.The subjects were 140 children from four to ten years old. Individual testwas adopted. The subjects were asked to make comparison of the velocities of twotoycars simultaneously and uniformly moving at the same speed under fourexperimental conditions. After the child had finished each item of the experiment, theexperimenter demanded him to give the reason of his answer no matterwhether the answer was correct or not. In this paper, the experimentalresults are only partly reported. These results indicates that children’s abilities tested with theexperimental items have a fair inter-correlation between them, andreactions of the same child to different items show a definite inter-consistency.
