Emotions can color people's attitudes toward unrelated objects in the environment. Existing evidence suggests that such emotional coloring is particularly strong when emotion-triggering information escapes conscious awareness. But is emotional reactivity stronger after nonconscious emotional provocation than after conscious emotional provocation, or does conscious processing specifically change the association between emotional reactivity and evaluations of unrelated objects? In this study, we independently indexed emotional reactivity and coloring as a function of emotional-stimulus awareness to disentangle these accounts. Specifically, we recorded skin-conductance responses to spiders and fearful faces, along with subsequent preferences for novel neutral faces during visually aware and unaware states. Fearful faces increased skin-conductance responses comparably in both stimulus-aware and stimulus-unaware conditions. Yet only when visual awareness was precluded did skin-conductance responses to fearful faces predict decreased likability of neutral faces. These findings suggest a regulatory role for conscious awareness in breaking otherwise automatic associations between physiological reactivity and evaluative emotional responses.
情绪会影响人们对环境中无关事物的态度。现有证据表明,当引发情绪的信息未被意识察觉时,这种情绪影响尤为强烈。但是,无意识情绪激发后的情绪反应性是否比有意识情绪激发后的更强,或者有意识加工是否会特别改变情绪反应性与无关事物评价之间的关联?在本研究中,我们将情绪反应性和情绪影响作为情绪刺激意识的函数进行独立测量,以厘清这些问题。具体而言,我们记录了对蜘蛛和恐惧面孔的皮肤电反应,以及随后在视觉觉察和未觉察状态下对新奇中性面孔的偏好。恐惧面孔在刺激觉察和刺激未觉察条件下均同等程度地增加了皮肤电反应。然而,只有当视觉觉察被排除时,对恐惧面孔的皮肤电反应才会预测中性面孔的喜爱度降低。这些发现表明,意识觉察在打破生理反应性与评价性情绪反应之间原本的自动关联方面具有调节作用。
