The interplay of stress and processing of self-relevant information

压力是由潜在的有害情况引起的，包括生理，情绪和行为反应。应激反应受几个参数的调节。对于压力处理来说，最重要的是确定压力源对身体和感知自我是重要的。威胁自我，例如通过增加社会评价元素，增强压力反应。有趣的是，通过单独激活自我也可以发现类似的效果：在压力情境中的视觉自我展示对压力反应产生了与威胁性社会评估小组相同的影响。我们最近可以证明，自我相似（变形）的面部肖像的呈现增强了在食欲和性欲刺激中发现的积极情绪效应。因此，我们假设自我相似性会增强和调节情绪/压力效应。惊吓和压力实验被用来研究自我相似性的认知机制，自我相似性是否与情感过程相互作用，以及它们是否与单纯的熟悉性效应分离。

Stress is elicited by potentially harmful situations, and consists of physiological, emotional and behavioral responses. Stress responses are modulated by several parameters. Most important for stress processing is that the stressor is identified to be significant for the physical and perceived self. Threatening the self, e.g. by adding a socially evaluating element, enhances stress reactivity. Interestingly, a similar effect can also be found by sole activation of the self: visual self-display during a stressful situation exerted the same effect on stress reactivity as a threatening social evaluation panel. We could recently show that the presentation of self-resembling (morphed) face portraits enhanced positive emotional effects found during appetitive, erotic stimulation. Thus, we postulate that self-resemblance will enhance and modulate emotional/stress effects. Startle and stress experiments are proposed to study the cognitive mechanisms of self-resemblance, whether selfresemblance interacts with affective processes, and whether they are separable from mere familiarity effects.
