This study examined how the source (an AI vs. a human) and veracity (true vs. false) of information affect memory recall over time. The experiment was based on a two-session design where participants were first presented with 2 videos from an AI or human source. After each video they were shown 16 statements  related to each video and one by one labeled which were true and false. Next they completed a cued recall task where they filled in missing words from the true and false statements. 51 participants were analyzed and divided into three delay groups (1, 2, or 5 days) to assess memory decay. It was predicted that participants would remember human presented and true statements better than AI presented and false ones. Results showed significant main effects of both source and veracity: participants recalled more human-generated and true statements than AI-generated and false ones. The findings also revealed a significant main effect of time: a memory decline between session 1 and session 2. However, the interaction between source, veracity and time was not significant. These findings suggest that source and veracity impact memory and forgetting follows a general decline over time. On a broader scale, this raises concerns about the potential risks of both misinformation and Artificial Intelligence, particularly in education, media platforms, and memory-based decision-making. Further research is needed to draw conclusions about how AI-generated misinformation may affect memory.
