参与者判断7种面部表情（中性，快乐，愤怒，悲伤，惊讶，恐惧和厌恶）中的哪一种被一组280张脸所显示，这些脸对应于卡罗林斯卡定向情感面孔数据库中的20名女性和20名男性模型（Lundqvist，Flykt & Ohman，1998）。每个人的脸在自由观看条件下（63名参与者），也为25，50，100，250和500毫秒（160名参与者），检查识别阈值。识别准确性，错误类型和反应时间的措施，获得每个表达式。一般来说，快乐的面孔比其他面孔更准确、更早、更快地被识别出来，而对恐惧面孔的判断是最不准确、最晚、最慢的。关于识别准确度、错误和反应时间的每个面部和表情的标准可以从www.psychonomic.org/archive/下载。
Participants judged which of seven facial expressions (neutrality, happiness, anger, sadness, surprise, fear, and disgust) were displayed by a set of 280 faces corresponding to 20 female and 20 male models of the Karolinska Directed Emotional Faces database (Lundqvist, Flykt & Ohman, 1998). Each face was presented under free-viewing conditions (to 63 participants) and also for 25, 50, 100, 250, and 500 msec (to 160 participants), to examine identification thresholds. Measures of identification accuracy, types of errors, and reaction times were obtained for each expression. In general, happy faces were identified more accurately, earlier, and faster than other faces, whereas judgments of fearful faces were the least accurate, the latest, and the slowest. Norms for each face and expression regarding level of identification accuracy, errors, and reaction times may be downloaded from www.psychonomic.org/archive/.
