However, the exact underlying mechanisms, such as sensory dominance possibly caused by imprecise priors and/or increased sensory precision, remain elusive. The “Bayesian brain” framework offers refined methods to investigate these mechanisms. This study utilized both model-free (frequentist statistics) and model-based (hierarchical Drift Diffusion Modeling) …
