如果让一个10岁以上的孩子,去抓一个缓慢飘动中的气球,他可以通过视觉来跟踪气球的飞行路线,并协调其手部的动作来对准移动中的气球。同时你也会发现,他在抓到气球之后,能马上回复身体的重心,而6岁左右的孩子是抓不到快速移动的球的,不过他会主动去追球,不管是跳开秋千去抓球还是对准目标把球踢回去,对他来说都很刺激。 If a child over the age of 10 grasps a slowly moving balloon, he can visually track the balloon’s flight path and coordinate the movement of his hand to align the moving balloon. At the same time, you will also find that he can immediately return to the center of gravity of the body after catching a balloon. However, a child around 6 years of age can not catch a fast-moving ball, but he will take the initiative to chase the ball. It’s exciting for him to catch the ball or to aim the ball back.
