基于代理模型的生成式AI在创意写作中的影响

Generative artificial intelligence (GenAI) is being rapidly adopted in education. Its effects on creativity unfold at both individual and collective levels. We develop an agent-based model that represents students’ creative outputs in a two-dimensional idea space to examine how GenAI assistance in creative writing shapes individual creativity and classroom-level idea diversity. Simulations show that GenAI increases individual creativity, with disproportionately larger gains for less creative students, while reducing collective diversity through idea homogenization. Critically, the model reveal
