Governing Mental-State Inference: Source-Neutral Regulatory Triggers and Tiered Obligations

Aug 01, 2026

This study addresses the fragmented regulatory landscape governing psychological state inference from diverse data sources—such as neural signals, text, or behavior—which is prone to circumvention and risks reifying unreliable inferences as psychological facts. The paper proposes a data-source-neutral regulatory framework that structures obligations across three distinct phases: elicitation, attribution, and use. It innovatively identifies two independent harm pathways and introduces a “seven-question, two-stage” assessment protocol to presumptively prohibit high-risk practices. Drawing on selective critical review, conceptual engineering, and functional comparison, the framework establishes a three-tiered, dynamic obligation-allocation mechanism. Regulatory stringency is calibrated according to factors including invasiveness, embodiment, and closed-loop capability, ensuring adaptability across both neural and non-neural psychological inference contexts.

Current large language models often suppress emotional expression due to preference alignment strategies, hindering their ability to exhibit human-like intelligence. This work proposes a self-rewarding reinforcement learning framework that operates without human-annotated feedback, leveraging a scoring-criterion-based self-reward mechanism combined with Group Relative Policy Optimization (GRPO) to systematically enhance the model’s capacities for emotional expression, intention communication, and self-awareness. Experimental results demonstrate that the approach significantly improves model robustness in scenarios involving flattery induction and ambiguous contexts. Although a slight performance degradation is observed on factual question-answering tasks, this study provides the first empirical validation of the feasibility of self-driven emotionally intelligent systems.
