On Agentic Behavioral Modeling
Treating AI models as cognitive hypotheses to explain behavior...
Researchers from leading European institutions have introduced agentic behavioral modeling (ABM), a formal framework that bridges theoretical neuroscience, decision theory, and AI. The paper, published on arXiv, treats artificial agents as latent, generative hypotheses about cognitive mechanisms and evaluates them based on statistical adequacy in explaining human behavioral data. The authors derive explicit conditional log-likelihoods for behavioral inference and validate model variants through parameter recovery simulations.
ABM is applied to two minimal laboratory paradigms: a binary perceptual contrast-discrimination task and a symmetric two-armed bandit learning task. The framework provides an agent-centric interpretation of the psychometric function, derives optimal policies, and mathematically proves the equivalence between Rescorla-Wagner learning and Bayesian inference in symmetric bandits. This work offers a practical foundation for applying ABM to cognitive behavioral science, enabling researchers to test AI-driven models against real human behavior.
