| Description: |
International audience ; This paper explores the brain correlates of conversational feedback (FB) in human-human and human-agent interactions, focusing on its impact on discourse and processing at semantic and communicative levels. The study investigates how FB, produced either congruously or incongruously, influences brain activity (EEG) during interactions between a doctor (the main speaker) and a patient (the recipient). The results reveal that FB is not processed at the semantic level, as there was no significant N400 component (which typically indicates semantic processing) to incongruous FB in either human-human or human-agent interactions. Instead, a P600 component was observed, particularly in human-human interactions, indicating that incongruous FB is processed through a repair strategy at the communicative/pragmatic level.Additionally, the study identifies a P200 component in human-agent interactions, which is stronger for congruous FB, indicating high predictability in agent-produced feedback. This effect was not observed in human-human interactions, where variability in feedback was higher. The findings highlight that FB's processing is more linked to predictability and repair strategies than to semantic content. The study also suggests that variability in feedback, particularly in human-human interactions, should be addressed in future research on feedback. |
