应激对记忆影响的脑科学研究及其教育启示

摘要/Abstract

摘要： 大量脑科学的研究揭示,应激对与海马相关的陈述性记忆的调节主要通过应激激素,尤其是糖皮质激素的分泌而发生作用,而影响的方向取决于一些调节变量,包括糖皮质激素升高的水平以及记忆的不同阶段等。研究发现基底外侧杏仁核是糖皮质激素对记忆不同阶段产生差异性影响的关键部位。因此,在教育过程中,既要科学地认识应激对记忆的消极影响,又要有效利用应激对记忆产生的调节作用,来提高学生的学习效率。

Abstract: Considerable data obtained form brain science research demonstrated that the impact of stress on hippocampal-dependent declarative memory was modulated through stress hormones, especially the Glucocorticoid. The direction of this effect, however, depends on many factors, such as the elevated glucocorticoid levels and the different phases of memory. There are differences in the effects of stress on the different phases of memory are dependent on the integrity of the basolateral amygdala. Therefore, educators should have scientific knowledge of the impairing effects of stress on memory and make good use of its beneficial effects to improve the students′ learning efficiency.
