Abstract
The spread of misinformation on social media has become a prevalent issue, and emerging AI technology further accerlates the generation of misinformation. In this study, we investigate how humans perceive AI-generated and human-written news differently and whether they can distinguish between the two. We conducted an experiment that asked participants to evaluate a news dataset consisting of 16 articles of different authenticity (True or Fake) and origin (Human or AI-generated). Physiological signals, including gaze and heart rate data were captured during the study for analysis. The goal was to predict how humans perceive human- and AI-generated news differently based on the collected physiological data. Various data analysis techniques were used to better understand physiological responses and news perceptions. The feasibility of predicting the origin of news, whether it is human- or AI-generated, and whether it is true or fake news based on the user data was assessed. Additionally, we explored how users' general personality and behavioral traits may relate to their ability to classify the news correctly.
