Decisions can arise in different ways, such as from a gut feeling, doing what worked last time, or planful deliberation. Different decision-making systems are dissociable behaviorally, map onto distinct brain systems, and have different computational demands. For instance, "model-free" decision strategies use prediction errors to estimate scalar action values from previous experience, while "model-based" strategies leverage internal forward models to generate and evaluate potentially rich… CONTINUE READING
