This study aims to examine how taboo content affects language learner psychology and language learning gains in a multi-modal learning environment by using facial expression analysis. 40 Muslim language learners were initially asked about their opinions on pork and watched a subtitled cooking video including pork visuals and their facial expressions were recorded. Before watching the video, only 20 of them were told it was lamb. The video was followed by a stimulated recall procedure, a cloze test and an output test. The results of the facial data analysis showed that Muslim learners were disgusted by the taboo content, which was in line with their opinions on pork taboo. However, this negative emotion did not significantly affect their test performance. Computer assisted facial expression analysis was also introduced as a biometric research technique for second language research.

禁忌内容对外语偶然词汇习得的影响：面部表情分析研究

本研究旨在通过面部表情分析来研究禁忌内容如何影响多模态学习环境中语言学习者的心理和语言学习收益。40 名穆斯林语言学习者最初被问及他们对猪肉的看法，并观看了带字幕的烹饪视频，包括猪肉的视觉效果和面部表情。在观看视频之前，只有 20 人被告知这是羊肉。视频之后是刺激回忆程序、完形填空测试和输出测试。面部数据分析结果显示，穆斯林学习者对禁忌内容感到厌恶，这与他们对猪肉禁忌的看法一致。然而，这种负面情绪并没有显着影响他们的测试表现。
