| description | The ability of metaphor comprehension reflects the cognitive status of elders. This study explored the ability of Chinese aMCI patients to access metaphorical meaning based on linguistic models of metaphor processing. ERPs were recorded from 30 aMCI patients and 30 control participants when judging the meaningfulness of literal sentences, conventional metaphors, novel metaphors, and anomalous expressions. The lower accuracy of the aMCI group revealed an impairment in metaphoric comprehension ability, but this difference was not reflected in ERPs data. In all participants, anomalous endings to sentences evoked the most negative N400 amplitude, whereas conventional metaphors evoked the smallest N400 amplitude. The LPC amplitude might be masked by a metaphor rebound effect when processing novel metaphors, which was consistent with the Graded Salience Model that novel metaphors needed further semantic integration. The results suggest that the aMCI patients may suffer an impairment in metaphorical meaning recognition, which the declined working memory may cause. |
