• Abstract: Human interactions are deeply rooted in the interplay of thoughts, beliefs, and desires made possible by Theory of Mind (ToM): our cognitive ability to understand the mental states of ourselves and others. Although ToM may come naturally to us, emulating it presents a challenge to even the most advanced Large Language Models (LLMs). Recent improvements to LLMs' reasoning capabilities from simple yet effective prompting techniques such as Chain-of-Thought have seen limited applicability to ToM. In this paper, we turn to the prominent cognitive science theory "Simulation Theory" to bridge this gap. We introduce SimToM, a novel two-stage prompting framework inspired by Simulation Theory's notion of perspective-taking. To implement this idea on current ToM benchmarks, SimToM first filters context based on what the character in question knows before answering a question about their mental state. Our approach, which requires no additional training and minimal prompt-tuning, shows substantial improvement over existing methods, and our analysis reveals the importance of perspective-taking to Theory-of-Mind capabilities. Our findings suggest perspective-taking as a promising direction for future research into improving LLMs' ToM capabilities.

  Large Language Models (LLMs) have recently shown a promise and emergence of Theory of Mind (ToM) ability. We propose a novel concept, taxonomy, and framework, the ToM reasoning with Zero, Finite, and Infinite Belief History. We have evaluated six LLMs with this game and found their performance on Zero Belief History is consistently better than on Finite Belief History.

  We propose Counterfactual Inception, a novel method that implants counterfactual thinking into Large Multi-modal Models. We aim for the models to engage with and generate responses that span a wider contextual scene understanding. Comprehensive analyses across various LMMs, including both open-source and proprietary models, corroborate that counterfactual thinking significantly reduces hallucination.

  Large Language Models (LLMs) have generated considerable interest and debate regarding their potential emergence of Theory of Mind (ToM) Several recent inquiries reveal a lack of robust ToM in these models and pose a pressing demand to develop new benchmarks. We taxonomize machine ToM into 7 mental state categories and delineate existing benchmarks to identify under-explored aspects of ToM.
