Abstract

We examined the effects of emotional response, with different levels of valence and arousal, on the temporal resolution of visual processing by using photos of various facial expressions. As an index of the temporal resolution of visual processing, we measured the minimum lengths of the noticeable durations for desaturated photographs using the method of constant stimuli by switching colorful facial expression photographs to desaturated versions of the same photographs. Experiments 1 and 2 used facial photographs that evoke various degrees of arousal and valence. Those photographs were prepared not only in an upright orientation but also in an inverted orientation to reduce emotional response without changing the photographs' image properties. Results showed that the minimum duration to notice monochrome photographs for anger, fear, and joy was shorter than that for a neutral face when viewing upright face photographs but not when viewing inverted face photographs. For Experiment 3, we used facial expression photographs to evoke various degrees of arousal. Results showed that the temporal resolution of visual processing increased with the degree of arousal. These results suggest that the arousal of emotional responses evoked by viewing facial expressions might increase the temporal resolution of visual processing.

观看面部表情图片所引起的情绪反应会导致更高的时间分辨率。
我们使用各种面部表情的照片,研究了不同情绪反应的价值和唤醒水平对视觉处理时间分辨率的影响。作为视觉处理时间分辨率的一个指标,我们使用恒定刺激法,通过将彩色面部表情照片切换为相同照片的去饱和版本,测量了去饱和照片的显著持续时间的最小长度。实验 1 和 2 使用了能唤起不同程度的兴奋和情绪的面部照片。为了在不改变照片图像属性的情况下减少情绪反应,这些照片不仅以直立的方向拍摄,还以倒置的方向拍摄。结果表明,在观看直立脸部照片时,注意到愤怒、恐惧和喜悦的单色照片的最短持续时间比注意到中性脸部照片的最短持续时间要短,但在观看倒置脸部照片时则不然。在实验 3 中,我们使用面部表情照片来诱发不同程度的兴奋。结果显示,视觉处理的时间分辨率随着唤醒程度的增加而增加。这些结果表明,观看面部表情所唤起的情绪反应可能会提高视觉处理的时间分辨率。
