当孩子说讨厌学习时,他的大脑正在发生什么
Jing Ji Guan Cha Wang· 2025-08-23 03:13
简简周说 当10岁的菲菲把作业本摔在地上时,她大脑中的情绪警报中心——杏仁核正过度激活,发出强烈的危险信号。这瞬间抑制了负责冷静思考与自我控制的大脑 指挥部——前额叶皮层的功能。这个时候,她很难做出家长所期待的明智行为。不是不想做到,而是做不到。所以,当孩子烦躁地喊出"我讨厌学习"时,不 是他"懒"或"不懂事",站在脑科学的角度,这是他的大脑在发出红色警报。理解这些科学真相,是帮助孩子的第一步。 1.为什么孩子一学习就烦躁 很多孩子都曾跟我说过,"我很想好好学,但不知道为什么,一看到学习的内容就觉得烦躁,看不下去。 曾经有个初三的男生,一到考试就肚子疼,甚至干呕。 脑成像显示,当他看到数学题时,他大脑中处理身体疼痛的区域(如前扣带回皮层、岛叶)竟然被激活了。 这从神经科学上证实,他的肚子疼、恶心,并不是装的,而是极度焦虑在身体上的真实表达。这种反应与大脑处理社会排斥和情感痛苦的神经网络被高度激 活有关。 神经科学领域的共识是,长期的压力激素(皮质醇)水平过高,还会损害海马体的健康——这是大脑中负责记忆编码的核心区域。 影像学研究证实,持续的高压状态与儿童及青少年海马体体积的缩小显著相关。 所以,当孩子持续在压 ...
