As network emojis play an increasingly important role in modern communications, the question of how semantic processing of emojis is performed in the context arises. By comparing the N400 and P600 effects of emojis and words in contextually incongruent conditions, we investigated the neural basis of semantic processing of emojis. We found that incongruent words elicited robust N400 and P600 effects, while emojis only generated a more conspicuous and sustained N400 effect. This suggests that emojis may have more difficult semantic retrieval versus words in the context, with potentially inefficient semantic integration. These data suggest that the semantic processing of network emojis in context is not the same as words and the meaning of emojis is more difficult to process at sentence level.
随着网络表情符号在现代通信中扮演着越来越重要的角色，关于表情符号在语境中的语义处理方式的问题也随之产生。我们通过比较语境不相符条件下表情符号和单词的 N400 和 P600 效应，研究了表情符号语义处理的神经基础。我们发现，不相符的单词会引起强烈的 N400 和 P600 效应，而表情符号只产生更明显和持续的 N400 效应。这表明，与语境中的单词相比，表情符号在语义检索方面可能更具挑战性，并且语义整合效率可能较低。这些数据表明，网络表情符号在语境中的语义处理方式与单词不同，表情符号的含义在句子层面上更难处理。
