最近的研究表明，情绪增强早期视力，但这一发现的普遍性仍然未知。情绪的好处是扩展到视觉的所有基本方面，还是范围有限？我们的研究结果表明，一个可怕的脸，与一个中性的脸相比，简短的介绍，提高了随后提出的低空间频率刺激的方向的敏感性，但降低了高空间频率刺激的方向敏感性。这是第一次证明情绪不仅会改善而且会损害低级视觉。选择性的低空间频率的好处是一致的想法，情绪增强大细胞处理。此外，我们认为高空间频率缺陷是由于大细胞和小细胞途径之间的抑制性相互作用造成的。我们的研究结果表明，情绪引起的权衡在视觉处理，而不是一个普遍的改善。这种权衡可能有利于感知维度，这些维度与生存相关，而牺牲了那些不太相关的维度。
Recent studies indicate that emotion enhances early vision, but the generality of this finding remains unknown. Do the benefits of emotion extend to all basic aspects of vision, or are they limited in scope? Our results show that the brief presentation of a fearful face, compared with a neutral face, enhances sensitivity for the orientation of subsequently presented low-spatial-frequency stimuli, but diminishes orientation sensitivity for high-spatial-frequency stimuli. This is the first demonstration that emotion not only improves but also impairs low-level vision. The selective low-spatial-frequency benefits are consistent with the idea that emotion enhances magnocellular processing. Additionally, we suggest that the high-spatial-frequency deficits are due to inhibitory interactions between magnocellular and parvocellular pathways. Our results suggest an emotion-induced trade-off in visual processing, rather than a general improvement. This trade-off may benefit perceptual dimensions that are relevant for survival at the expense of those that are less relevant.
