The brain forms certain deliberative decisions following normative principles related to how sensory observations are weighed and accumulated over time. Previously we showed that these can account for people adapt their the temporal dynamics of (Glaze et al., 2015). Here show this adaptability extends accounting correlations in observations, which have a dramatic impact on weight evidence provided by those observations. We tested online human participants novel visual-discrimination task with pairwise-correlated With minimal training, adapted uncued, trial-by-trial changes produced based an approximately weighting accumulation evidence. results highlight robustness our brain’s ability process respect not just physical features but also they provide given decision.
