Study of the Influence of AI Powered Virtual Agent Design on the Illusion of Understanding in Middle School Students

This repository contains the data and materials for a between-groups experiment (N=119 middle school students, ages 11-13) investigating how the visual design of an AI-powered virtual agent (humanoid vs. abstract) influences the Illusion of Understanding. The study measured perceived anthropomorphism, multidimensional trust, perceived persuasion, self-assessed understanding (IOED protocol), and objective knowledge in a history education context (ancient Egyptian mummification).
