幼儿时期是身心迅速发展的时期,潜力很大。人的大脑皮质是人类各种行为的最高调节器,也是人的心理活动的场所。据生理、心理学家研究,婴儿出生时,大脑皮质就有140亿个神经细胞,但体积小,互相分离,还不能形成条件反射。在出生到三岁期间,大脑皮质的神经细胞则成熟得十分迅速:细胞体积迅速增大,神经纤维迅速增长,特别是神经纤维的髓鞘化过程非常迅速,到三岁时已经有70%—80%的细胞完成 Early childhood is the rapid development of physical and mental period, great potential. Human cerebral cortex is the highest regulator of all kinds of human behavior, but also the place of human psychological activity. According to physiology, psychologists study, when a baby is born, the cerebral cortex has 140 billion nerve cells, but small in size, separated from each other, can not form the conditioned reflex. During the first trimester of life, neurons in the cerebral cortex matured very rapidly: the volume of the cells increased rapidly, the number of nerve fibers increased rapidly, and the myelination process of nerve fibers in particular was very rapid. By the age of three, 70% 80% of the cells are done
