Identifying Informative Environments for Cognition Parameter Inference via Bayesian Experimental Design
Bayesian inverse planning, cognitive modeling, experimental design
Introduces amortized Bayesian Experimental Design (BED) to select optimal experimental environments for cognitive parameter inference Validates approach on Mouselab-MDP paradigm, showing near-equivalent performance to exact Monte Carlo BED at lower computational cost Finds no universally optimal environment—trade-offs exist between information gain, posterior recoverability, and efficiency
Emphasizes computational efficiency and theoretical principledness; minimizes domain-specific limitations, absence of human-subject validation beyond Mouselab-MDP, and lack of comparison to non-Bayesian or heuristic design approaches.
Foundational methodological contribution enabling more rigorous, efficient, and objective-aware cognitive science.
New AI method selects best experiments for studying human cognition, cutting computation time while preserving accuracy.
No human behavioral outcomes reported from BED-designed experiments; No discussion of implementation barriers for labs without Bayesian computation infrastructure; No benchmark against existing environment-selection heuristics used in practice
It combines credibility signals from formal Bayesian framing, benchmarking against an 'exact' gold standard, and empirical validation on a recognized paradigm—but makes the advance feel broader and more immediately applicable than the evidence supports, since generalizability, human behavioral impact, and comparative baselines remain unaddressed.
Amortized Bayesian experimental design closely matches the environment rankings of exact Monte Carlo BED while substantially reducing computational cost.
Experiments on the Mouselab-MDP process-tracing paradigm show that amortized BED closely matches the environment rankings of exact Monte Carlo BED while substantially reducing computational cost.
