本研究的重点是年龄和社会经济地位对认知挑战性任务应激反应的差异。具体来说，我们评估了皮质醇的人体内轨迹，皮质醇是肾上腺在面对压力源时释放的一种类固醇激素，在暴露于具有认知挑战性的任务之前、期间和之后。我们通过同时检查生理反应的年龄和SES差异来扩展当前的文献。研究结果表明，年龄和社会经济地位在反应性中都起着重要作用，因此，社会经济地位较高的老年人对认知压力源的生理反应最强烈。讨论了这些发现对认知衰老研究的意义。
The present study focused on age and SES differences in stress reactivity in response to cognitively challenging tasks. Specifically, we assessed within-person trajectories of cortisol, a steroid hormone released by the adrenal gland in response to stressors, before, during, and after exposure to cognitively challenging tasks. We extend the current literature by simultaneously examining age and SES differences in physiological reactivity. Findings suggest that age and SES both play an important role in reactivity, such that it was the older adults with higher SES who were the most physiologically reactive to cognitive stressors. Implications of these findings for cognitive aging research are discussed.
