This study investigated emoji semantic processing by measuring changes in event-related electroencephalogram (EEG) power. The last segment of experimental sentences was designed as either words or emojis consistent or inconsistent with the sentential context. The results showed that incongruent emojis led to a conspicuous increase of theta power (4-7 Hz), while incongruent words induced a decrease. Furthermore, the theta power increase was observed at midfrontal, occipital and bilateral temporal lobes with emojis. This suggests a higher working memory load for monitoring errors, difficulty of form recognition and concept retrieval in emoji semantic processing. It implies different neuro-cognitive processes involved in the semantic processing of emojis and words.
本研究通过测量事件相关脑电图（EEG）功率的变化来研究 emoji 的语义处理。实验句子的最后一个片段设计为与句子语境一致或不一致的单词或表情符号。结果表明，不一致的表情符号导致θ波（4-7 Hz）明显增加，而不一致的单词则导致θ波减少。此外，用表情符号时，θ波的增加出现在额中、枕部和双侧颞叶。这表明在 emoji 语义处理中，监控错误、形式识别和概念检索的工作记忆负荷更高。这表明 emoji 和单词的语义处理涉及不同的神经认知过程。
