快速检测和优先处理我们周围相关信息的能力对于我们与环境互动的方式至关重要。选择性注意力是实现这一目的的关键机制,可以提高许多视觉任务的表现。对突发信息的反射性注意有助于发现阻碍性威胁或危险,这可能是情绪调节选择性注意影响感知的原因。例如,突然出现一张恐惧的脸会增强外源性(非自愿的,刺激驱动的)注意力对表现的影响。特质焦虑等内部状态也可以调节注意力对早期视觉处理的影响。然而,注意力不仅能提高表现,它还能改变视觉信息呈现给我们的方式,例如通过增强感知的对比度。在这里,我们表明,情绪增强了外源性注意的效果,性能和感知对比。此外,我们发现特质焦虑介导这些影响,在焦虑的观察者中,注意力和情绪的影响更大。最后,表现和外观的变化相互关联,可能反映了共同的注意力调节。总而言之,我们的研究结果表明,情绪和焦虑与选择性注意相互作用,真正改变了我们的看法。
The ability to swiftly detect and prioritize the processing of relevant information around us is critical for the way we interact with our environment. Selective attention is a key mechanism that serves this purpose, improving performance in numerous visual tasks. Reflexively attending to sudden information helps detect impeding threat or danger, a possible reason why emotion modulates the way selective attention affects perception. For instance, the sudden appearance of a fearful face potentiates the effects of exogenous (involuntary, stimulus-driven) attention on performance. Internal states such as trait anxiety can also modulate the impact of attention on early visual processing. However, attention does not only improve performance; it also alters the way visual information appears to us, e.g. by enhancing perceived contrast. Here we show that emotion potentiates the effects of exogenous attention on both performance and perceived contrast. Moreover, we found that trait anxiety mediates these effects, with stronger influences of attention and emotion in anxious observers. Finally, changes in performance and appearance correlated with each other, likely reflecting common attentional modulations. Altogether, our findings show that emotion and anxiety interact with selective attention to truly alter how we see.
