本研究考察了压力挑战对大学生情绪词加工的影响。应激诱导是通过竞争性的计算机任务实现的。在这种情况下，个人要么一再输给邦联，要么战胜邦联。心情，注意。在研究期间记录皮质醇和皮质醇。研究发现：(1)处于负性应激源条件下的受试者将注意力从负性词语上转移的速度比处于正性或中性词语的受试者更快；(2)注意力从负性词语上的转移与压力引起的情绪低落有关；(3)处于负性应激条件下的受试者在贝克抑郁量表上得分较高时，较慢地将注意力从所有刺激物上抽离；(4)在实验阶段，抑郁得分升高与皮质醇变化较低有关。在恢复期皮质醇水平较高。这些发现指出，信息处理策略是调节情绪的一种手段，认知和肾上腺皮质功能的非典型特征可能是抑郁症的假定风险标志。
The effects of a stressful challenge on the processing of emotional words were examined in college students. Stress induction was achieved using a competitive computer task. where the individual either repeatedly lost or won against a confederate. Mood, attention. and cortisol were recorded during the study. There were four findings: (I) Participants in the negative stressor condition were faster to shift attention away from negative words than positive or neutral words: (2) attentional shifts away from negative words were associated with stress-induced mood lowering; (3) participants in the negative stress condition with elevated scores on the Beck Depression Inventory were slow to disengage attention from all stimuli: and (4) elevated depression scores were associated with lower cortisol change from baseline during the experimental phase. and with higher cortisol levels during the recovery phase. These findings point to information-processing strategies as a means to regulate emotion, and to at atypical features of cognitive and adrenocortical function that may serve as putative risk markers of depression.
