三个实验研究了快乐面孔的识别速度优势。结果重复了早期的发现，表明积极（快乐）的面部表情比消极（厌恶或悲伤）的面部表情更快地被识别（实验1和2）。此外，结果表明，这种效果是明显的，即使当积极和消极的面孔之间的低层次的物理差异控制使用示意性的面孔（实验2），该效果是不归因于一个工件所产生的促进识别的一个特征，在快乐的面孔（上翘的嘴角线，实验3）。总之，这些结果表明，快乐的面孔优势可能反映了情感积极和消极信号的识别和分类的更高层次的不对称性。
Three experiments examined the recognition speed advantage for happy faces. The results replicated earlier findings by showing that positive (happy) facial expressions were recognized faster than negative (disgusted or sad) facial expressions (Experiments 1 and 2). In addition, the results showed that this effect was evident even when low-level physical differences between positive and negative faces were controlled by using schematic faces (Experiment 2), and that the effect was not attributable to an artifact arising from facilitated recognition of a single feature in the happy faces (up-turned mouth line, Experiment 3). Together, these results suggest that the happy face advantage may reflect a higher-level asymmetry in the recognition and categorization of emotionally positive and negative signals.
