The current study investigated the effects of presentation time and fixation to expression-specific diagnostic features on emotion discrimination performance, in a backward masking task. While no differences were found when stimuli were presented for 16.67 ms, differences between facial emotions emerged beyond the happy-superiority effect at presentation times as early as 50 ms. Happy expressions were best discriminated, followed by neutral and disgusted, then surprised, and finally fearful expressions presented for 50 and 100 ms. While performance was not improved by the use of expression-specific diagnostic facial features, performance increased with presentation time for all emotions. Results support the idea of an integration of facial features (holistic processing) varying as a function of emotion and presentation time.
在一项后向掩蔽任务中，当前研究调查了呈现时间和对特定表情诊断特征的注视对情绪辨别表现的影响。当刺激呈现16.67毫秒时未发现差异，但早在50毫秒的呈现时间，面部情绪之间的差异就超出了快乐优势效应。快乐表情最容易被辨别，其次是中性和厌恶表情，然后是惊讶表情，最后是呈现50毫秒和100毫秒的恐惧表情。虽然使用特定表情的诊断性面部特征并没有提高表现，但所有情绪的表现都随着呈现时间的增加而提高。结果支持了面部特征整合（整体加工）随情绪和呈现时间而变化的观点。
