Comparative Observational Report on Turn-Taking, Cognitive Stability, and Response Regulation in Large Language Models

This record documents a comparative observational study of multiple large language models (including GPT, Perplexity, GenSpark, Grok, and Gemini) under controlled interaction conditions. The report focuses on turn-taking behavior, response interruption, cognitive continuity, and stability during extended human interaction, both with and without structured cognitive frameworks. The objective is not to evaluate model performance metrics, but to document qualitative behavioral differences relevant to human safety, mental health contexts, and ethical AI deployment. This record is complementary to the institutional positioning of the TCF/TBF framework and does not disclose proprietary or methodological implementation details.
