About Me

Hi! I am a cognitive scientist interested in the nature and origins of the uniquely human mind and intelligence. My research draws insights and methods from philosophy, evolutionary theory, experimental psychology (cognitive, social, developmental, and computational), and artificial intelligence to investigate uniquely human agentic structures and behaviors and their significance in social coordination contexts. My recent research focuses on collaboration among humans (children and adults), AI agents (including RL- and LLM-based systems), and their interactions, with the goal of advancing more human-like and human-compatible AI systems.

I’m currently a postdoc collaborating with computational cognitive scientist Tao Gao at UCLA and with developmental psychologists Tamar Kushnir and Michael Tomasello at Duke University.

   This paper establishes the phenomenon of intentional commitment and discusses the social-cognitive mechanisms underlying it.

Cheng, S., Zhu, J., Zhou J., Shen, M., & Gao T. (2025). Spontaneous Coordination with Self-Commitment: How the Presence of Others Alters the Strength, Goal and Timing of Commitment. Cognition. [preprint-version]
   This paper explores a social origin of spontaneous intentional commitment. We propose a “social inner eye” hypothesis, assuming commitment in individual decision-making arises from an internalized self-presentation, transferring the audience of commitment from a real partner to an inner eye perspective. We demonstrate how social context influences the strength, content, and timing of individual commitment.
