Abstract

This paper investigates the role of anthropomorphic design in Large Language Models (LLMs), particularly in the context of lifestyle behavior change coaching. This study examines how specific verbal social cues – namely small talk and self-referential social cues – affect user perceptions of anthropomorphism, trust, and eeriness. Findings from a 2x2 experiment show that self-referential social cues enhance perceptions of anthropomorphism, which in turn positively influence user trust. At the same time, the combined use self-referential social cues and small talk can have adverse effects, suggesting a potential uncanny valley effect in text-based interactions. These results highlight the nuanced role of verbal social cues in shaping user perceptions and provide insights for designing more effective and trustworthy LLM-based coaching systems.

At the same time, the combined use self-referential social cues and small talk can have adverse effects, suggesting a potential uncanny valley effect in text-based interactions.
