A substantial amount of research has demonstrated the deleterious effects of chronic stress on memory. However, much less is known about protective factors. In the current study we test the role of maternal responsiveness in buffering the effects of childhood allostatic load on subsequent adolescent working memory. Allostatic load is a marker of cumulative stress on the body that is caused by mobilization of multiple physiological systems in response to chronic environmental demands. Results of the study suggest that allostatic load negatively affects working memory, but that this effect is significantly attenuated in children with responsive mothers.
大量研究表明，慢性压力对记忆有不良影响。然而，关于保护因素知之甚少。在当前的研究中，我们测试了母亲反应能力在缓冲童年期适应负荷对随后青少年工作记忆的影响中的作用。适应负荷是身体累积压力的标志，是由多个生理系统对慢性环境需求的动员引起的。研究结果表明，适应负荷对工作记忆有负面影响，但在有反应能力的母亲的孩子中，这种影响显著减弱。
