A preliminary study on the Noh mask test for analysis of recognition of facial expression was performed. The present study was conducted on 15 normal subjects (mean age: 32 years, SD 9.7 years) as the first step to test for the differences between psychiatric patients and normal subjects. Stimuli were created by photographs of 15 Noh masks at different vertical angles. Subjects were given 12 tasks (12 emotion items), and each task consisted of 15 trials (15 Noh mask images). In each trial, the subject viewed a colour monitor, and was shown an emotion item, followed by a Noh mask image. The subject pressed either the yes or no key to indicate whether the Noh mask image expressed the emotion item. The subject's response and reaction time to each Noh mask image showed no deviation, although the subject's response and reaction time to each emotion item showed some deviation. As the vertical angle of the Noh mask changed, normal subjects recognized all emotion items except the 'uncanny' expression. Factor analysis of the 15 Noh mask images produced three factors, and the analysis of 12 emotion items produced five factors. Thus, the Noh mask test was simplified to nine images and nine items. Further developments of the Noh mask test may include the evaluation of the dysfunction of perception on delicate facial expression in psychiatric patients.
开展了一项关于能剧面具测试以分析面部表情识别的初步研究。本研究以15名正常受试者（平均年龄：32岁，标准差9.7岁）为对象，作为测试精神科患者与正常受试者之间差异的第一步。刺激物由15个不同垂直角度的能剧面具照片制成。受试者被给予12项任务（12种情感项目），每项任务由15次试验（15张能剧面具图像）组成。在每次试验中，受试者观看彩色显示器，先展示一个情感项目，然后是一张能剧面具图像。受试者按下“是”或“否”键来表明能剧面具图像是否表达了该情感项目。尽管受试者对每个情感项目的反应和反应时间存在一些偏差，但对每张能剧面具图像的反应和反应时间没有偏差。随着能剧面具垂直角度的变化，正常受试者能识别除“离奇”表情外的所有情感项目。对15张能剧面具图像的因子分析产生了三个因子，对12种情感项目的分析产生了五个因子。因此，能剧面具测试被简化为九张图像和九个项目。能剧面具测试的进一步发展可能包括评估精神科患者对微妙面部表情的感知功能障碍。
