We could, in principle, define normative models in terms of the behavioral steps involved in making a good judgment or decision. For example, we could define the normative model for subtraction problems in terms of the steps of subtracting digits, regrouping, etc.But, as just illustrated, most normative models in JDM do not do this and are thus not computational, in the sense of being specified as procedures.rescriptive models are designs for improvement. If normative models fall in the domain of philosophy (broadly defined) and descriptive models in the domain of empirical psychological science, then prescriptive models are in the domain of engineering (again, broadly defined).
The optimality model is a tool used to evaluate the effects of costs and benefits on animal behavior in the natural world. This evaluation allows researchers to make predictions about an animalâs optimal behavior. Optimality modeling is the modeling aspect of optimization theory. It allows for the visualization of the costs and benefits that influence the outcome of a decision and contributes to an understanding of animal adaptations.
