  • Computational psychiatry attempts to apply mathematical and computational techniques to help improve psychiatric care. Here, we consider formal valuation accounts of emotion. The flexibility of emotional responses and the nature of appraisals suggest the need for a model-based framework for emotions. Resource limitations make plain model-based valuation impossible, and require strategies to apportion cognitive resources adaptively. We argue that emotions can implement such approximations by restricting the range of behaviours and states considered. We consider the processes that guide the deployment of the emotional approximations, discerning between innate, model-free, heuristic and model-based controllers. A focus on complex model-based decisions reveals the necessity for strategies to deal with the complexity of the problems. Emotions may provide such approximations, and this framework may provide a principled approach to examining them.
