However, few systematic studies have been conducted on the differences in brain activation between human and artificial voices in newscasts. This paper aims to investigate the psychophysiological effects of the media in Chinese contexts when different agents (AI or human) broadcast different types (emotional\/neutral) of news. Comparing the electrophysiological data of the participants\u2019 EEG while listening to different newscast agents revealed that brain activity responses were greater when listening to a human newscast than to an AI voice newscast. And \u03b2 bands in left posterior temporal lobe were significantly different, suggesting that participants\u2019 brain were better at processing, comprehending auditory information, and storing working memory when listening to a human reporter than when listening to a voice generated by AI. Moreover, the ERP results and the interaction effect of content valence and agent voice demonstrated that the human voice generated greater cognitive effect, which may reflect participants\u2019 trust in the credibility and fluency of the human voice news. This study demonstrates the importance of further research into cognitive effects of AI journalism.<\/jats:p>","DOI":"10.3389\/fpsyg.2023.1243078","type":"journal-article","created":{"date-parts":[[2023,11,23]],"date-time":"2023-11-23T11:53:02Z","timestamp":1700740382000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":14,"title":["AI voices reduce cognitive activity?
