A formalized representation of a class of phenomena (e.g., complex systems) that is simplified by ignoring certain details. It derives from a theory and can become a kind of mini-theory when it characterizes a process and serves to guide and develop the theory further. In science, a model can be either descriptive or predictive. A predictive model in mathematics or statistics is an equation or set of rules making it possible to predict the dependent variable or the output of a system (e.g., Newton’s equations for his laws of motion). A descriptive model aids in understanding the underlying processes or behavior of a system (e.g., the model of working memory). A model may be used as the basis of simulation or for the purposes of drawing analogies. Analogical models allow the functioning of a new system to be understood by comparing it with that of a familiar system, and as such can serve as an important aid in promoting interdisciplinary research.
