Using Large Language Model agents to simulate human game behaviors offers valuable insights for human social psychology in anthropomorphic AI research. While current models rely on static personality traits, real-world evidence shows personality evolves through environmental feedback. Recent work introduced dynamic personality traits but lacked natural selection processes and direct psychological metrics, failing to accurately capture authentic dynamic personality variations. To address these limitations, we propose an enhanced framework within the Prisoner’s Dilemma, a socially significant scenario. By using game payoffs as environmental feedback, we drive adaptive personality evolution and analyze correlations between personality metrics and behavior. Our framework reveals new behavioral patterns of agents and evaluates personality-behavior relationships, advancing agent-based social simulations and human-AI symbiosis research.

Large language models (LLMs) have advanced document-level relation extraction (DocRE), but DocRE is more complex than sentence-level relation extraction (SentRE), facing challenges like diverse relation types, coreference resolution and long-distance dependencies. Traditional pipeline methods, which detect relations before generating triplets, often propagate errors and harm performance. Meanwhile, fine-tuning methods require extensive human-annotated data, and in-context learning (ICL) underperforms compared to supervised approaches. We propose an iterative reflection framework for DocRE, inspired by human non-linear reading cognition. The framework leverages explicit and implicit relations between triplets to provide feedback for LLMs refinement. Explicit feedback uses logical rules-based reasoning, while implicit feedback reconstructs triplets into documents for comparison. This dual-process iteration mimics human semantic cognition, enabling dynamic optimization through self-generated supervision. For the first time, this achieves zero-shot performance comparable to fully supervised models. Experiments show our method surpasses existing LLM-based approaches and matches state-of-the-art BERT-based methods.
