训练有素的评委（66 名大学生）区分受试者的面部表情，包括真正的疼痛（手浸在冰水中）、掩盖的疼痛、摆出姿势的疼痛或无疼痛。法官接受面部动作训练（基于面部动作编码系统）加上有限的反馈训练、仅反馈训练或不训练。所有法官，无论是否接受过培训，在检测表现出低疼痛耐受性的受试者的真实疼痛方面都比高耐受性受试者更准确。相对于没有训练，反馈训练提高了识别姿势疼痛和真实疼痛的准确性，而面部动作训练加反馈则提高了识别姿势疼痛的准确性。结果表明，可以向法官提供有关面部运动的信息，以区分真实的疼痛表现和扭曲的疼痛表现。
Trained judges (66 college students) distinguished facial expressions of subjects in genuine pain (hand in ice water), masked pain, posed pain, or no pain. Judges were given facial movement training (based on Facial Action Coding System) plus limited feedback training, feedback only training, or no training. All judges, regardless of training, were more accurate in detecting genuine pain in subjects demonstrating low pain tolerance than in subjects with high tolerance. Relative to no training, feedback training enhanced accuracy in identifying posed and genuine pain, whereas facial action training plus feedback enhanced accuracy in identifying posed pain. Results suggest judges can be provided with information about facial movements to distinguish between genuine and distorted pain displays.
