情绪面部表情的物理强度对感知强度和情绪类别解码准确性的影响进行了评估，愤怒，厌恶，悲伤和快乐的表情。两个男人和两个女人的面部表情构成的四种情绪被用作刺激。使用图形变形程序为每个姿势创建六个不同的表达强度水平。12名男性和12名女性对96种刺激中的每一种进行了评分，以感知潜在情绪的强度和所表达情绪的定性性质。结果表明，知觉强度与表情的物理强度呈线性关系。情绪类别解码的准确性在很大程度上与操纵的物理强度的表达愤怒，厌恶和悲伤的表达。仅就幸福表情而言，研究结果与分类判断过程一致。编码器的性别产生显着影响的两个依赖措施。这些影响仍然存在，即使在编码中可能存在的性别差异得到控制，这表明解码器的感知偏见。
The influence of the physical intensity of emotional facial expressions on perceived intensity and emotion category decoding accuracy was assessed for expressions of anger, disgust, sadness, and happiness. The facial expressions of two men and two women posing each of the four emotions were used as stimuli. Six different levels of intensity of expression were created for each pose using a graphics morphing program. Twelve men and 12 women rated each of the 96 stimuli for perceived intensity of the underlying emotion and for the qualitative nature of the emotion expressed. The results revealed that perceived intensity varied linearly with the manipulated physical intensity of the expression. Emotion category decoding accuracy varied largely linearly with the manipulated physical intensity of the expression for expressions of anger, disgust, and sadness. For the happiness expressions only, the findings were consistent with a categorical judgment process. Sex of encoder produced significant effects for both dependent measures. These effects remained even after possible gender differences in encoding were controlled for, suggesting a perceptual bias on the part of the decoders.
