Normative decision rules in changing environments.

ABSTRACT: Models based on normative principles have played a major role in our understanding of how the brain forms decisions. However, these models have typically been derived for simple, stable conditions, and their relevance to decisions formed under more naturalistic, dynamic conditions is unclear. We previously derived a normative decision model in which evidence accumulation is adapted to fluctuations in the evidence-generating process that occur during a single decision (Glaze et al., 2015), but the evolution of commitment rules (e.g., thresholds on the accumulated evidence) under dynamic conditions is not fully understood. Here we derive a normative model for decisions based on changing contexts, which we define as changes in evidence quality or reward, over the course of a single decision.
