Researchers have developed a new framework for designing cognitive experiments to better infer underlying cognitive mechanisms. This Bayesian Experimental Design (BED) approach treats the experimental environment as a variable, aiming to identify the most informative settings for parameter inference. An exact Monte Carlo BED benchmark was established, alongside an amortized BED framework for efficient evaluation. Experiments on the Mouselab-MDP paradigm demonstrated that the amortized BED closely matches exact Monte Carlo rankings while significantly reducing computational costs. The study also revealed that no single environment is universally optimal, highlighting trade-offs between information gain, posterior recoverability, and efficiency. AI
