From Stateless to Situated: Building a Psychological World for LLM-Based Agents

arXiv cs.AI · 6 hours ago

Researchers propose LEKIA 2.0, an LLM architecture that separates cognitive and executive layers to maintain temporal awareness and user boundaries across multiple conversation turns in emotional support scenarios. The system achieved approximately 31% absolute improvement over prompt-only baselines in completing deep intervention loops. This external situational structure enables LLM-based emotional support systems to track user state and consent boundaries consistently throughout ongoing interactions rather than treating each response independently.
