Prior evidence has shown that a person's affective context influences attention to emotional stimuli. The present study investigated whether a crossmodal affective context that is induced by remembering an emotional sound modulates attention to visual emotional stimuli. One group of participants had to remember a positive, negative, or neutral sound during each trial of a dot probe paradigm. A second group of participants also had to encode the valence of the sound. The results revealed that attention was preferentially deployed to stimuli that were emotionally congruent to the affective context. However, this effect was only evident when participants had to encode the valence of the affective context. These findings suggest that a crossmodal affective context modulates the deployment of attention to emotional stimuli provided that the affective connotation of the context is task-relevant.
先前的证据表明，一个人的情感背景会影响对情绪刺激的注意力。本研究探讨了由回忆情绪声音引起的跨模态情感背景是否会调节对视觉情绪刺激的注意力。一组参与者在点探测范式的每次试验中必须记住积极、消极或中性的声音。第二组参与者还必须对声音的效价进行编码。结果表明，注意力优先投向与情感背景情绪一致的刺激。然而，只有当参与者必须对情感背景的效价进行编码时，才会出现这种影响。这些发现表明，跨模态情感背景会调节对情绪刺激的注意力分配，前提是背景的情感内涵与任务相关。
