最近的证据表明，工作记忆受到 负面情绪状态及其伴随的皮质醇释放。 本项目将研究积极和消极的影响， 情绪和皮质醇反应对信息处理的影响。 中 完全在受试者内设计，参与者将在三个测试 在紧张的一天，他们将在完成一系列心理任务之前， 在一个旨在引起皮质醇释放的压力源之后， 情绪;在一个积极的情绪日，任务将在 在看了一部能产生积极情绪的电影后， 响应;在第三天，任务将在 对情绪或皮质醇影响最小的休息时间。 任务将测量工作记忆和感觉辨别力， 被认为受情绪和皮质醇不同影响的过程 分泌物 为了全面检查应激激素的活动， 任务，皮质醇将在重复的唾液样本中进行测量 在整个实验过程中。 心理任务表现将 作为因变量，特别注意 皮质醇水平、报告的情绪和表现之间的关联 在任务上。 这项研究可能对理解 伴随情绪障碍的认知改变， 抑郁症

Recent evidence suggests that working memory is strongly influenced by negative emotional states and their accompanying cortisol release. This project will examine the influence of positive and negative emotions and cortisol responses on information processing. In a completely within-subjects design, participants will be tested on three days: On a stress day, they will complete a set of mental tasks prior to and following a stressor designed to elicit cortisol release and negative moods; on a positive mood day, the tasks will be performed before and after a film known to produce positive emotions with no cortisol response; on the third day, tasks will be administered before and after a rest period having minimal effects on either moods or cortisol. Tasks will measure working memory and sensory discrimination, two processes thought to be affected differentially by emotions and cortisol secretion. To fully examine the activity of stress hormones during the tasks, cortisol will be measured in repeated saliva samples taken throughout the experimental sessions. Mental task performance will serve as the dependent variable with special attention paid to associations between cortisol levels, reported moods and performance on the tasks. This research may have implications for understanding cognitive alterations accompanying emotional disorders such as depressive illness.
