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).
