Emotion perception of facial expressions involves two processes: quick approach-avoidance responses and subsequent sorting into emotional categories (i.e., happiness, anger), considering the context. Sorting of morphed ambiguous facial expressions is known to occur categorically, but the occurrence of approach-avoidance responses for morphed facial expressions is yet to be investigated. The present study used morphed angry and fearful facial expressions and measured approach-avoidance responses among Japanese university students (Experiment 1, n = 29). Similar experiments with linguistic load (Experiment 2, n = 28) and visual load (Experiment 3, n = 29) were conducted. The results indicated categorical perception in the sorting of facial expressions but no approach-avoidance response for morphed expressions. Furthermore, linguistic load affected the categorisation of facial expressions, but neither linguistic load nor visual load affected the approach-avoidance response. These results support the idea that the non-linguistic approach-avoidance response and the linguistic categorisation of facial expressions are two different processes. The nature of the emotional perception process is also discussed.
快速接近-回避反应，以及随后根据情境将其分类为情绪类别（即快乐、愤怒）。已知对变形的模糊面部表情进行分类是分类的，但对变形面部表情的接近-回避反应的发生仍有待研究。本研究使用变形的愤怒和恐惧面部表情，并在日本大学生中测量接近-回避反应（实验 1，n=29）。进行了具有语言负荷（实验 2，n=28）和视觉负荷（实验 3，n=29）的类似实验。结果表明，在面部表情的分类中存在分类感知，但对变形表情没有接近-回避反应。此外，语言负荷会影响面部表情的分类，但语言负荷和视觉负荷都不会影响接近-回避反应。这些结果支持这样一种观点，即非语言的接近-回避反应和面部表情的语言分类是两个不同的过程。还讨论了情绪感知过程的性质。
