The Japanese and Caucasian Brief Affect Recognition Task (JACBART) has been proposed as a standardized method for measuring people's ability to accurately categorize briefly presented images of facial expressions. However, the factors that impact performance in this task are not entirely understood. The current study sought to explore the role of the forward mask's duration (i.e., fixed vs. variable) in brief affect categorization across expressions of the six basic emotions (i.e., anger, disgust, fear, happiness, sadness, and surprise) and three presentation times (i.e., 17, 67, and 500 ms). Current findings do not demonstrate evidence that a variable duration forward mask negatively impacts brief affect categorization. However, efficiency and necessity thresholds were observed to vary across the expressions of emotion. Further exploration of the temporal dynamics of facial affect categorization will therefore require a consideration of these differences.
日本人和高加索人的简短情感识别任务（JACBART）已被提议作为一种标准化方法，用于测量人们准确分类短暂呈现的面部表情图像的能力。然而，影响该任务表现的因素尚未完全明确。本研究旨在探讨前向掩蔽持续时间（即固定与可变）在六种基本情绪（即愤怒、厌恶、恐惧、快乐、悲伤和惊讶）的表情分类以及三种呈现时间（即17、67和500毫秒）下的简短情感分类中的作用。目前的研究结果并未证明可变持续时间的前向掩蔽会对简短情感分类产生负面影响。然而，观察到效率和必要性阈值在不同情绪表达之间存在差异。因此，进一步探索面部情感分类的时间动态将需要考虑这些差异。
