A Cognitive Model of New Data on Human Problem Solving Essay -- Psycho

A cognitive Model of New info on human Problem SolvingI. Project Descriptioncognitive modeling is the creation of models which resemble and explain the way in which gentleman do things. What makes them so interesting to me is the process though which cognitive scientists go in order to create these models. cognitive scientists often use a generative possibility in creating such models. A generative surmise is a theory that explains a set of empirical observations by genuinely generating them (as opposed to just summarizing them or characterizing them with equations or logic). Thus, a generative theory has to be executable, like a computer program or a recipe.The system on which Im basing my work is named Cascade (VenLehn, Jones & chi, 1991). Cascade was primitively developed to explain the cognitive mechanisms involved in the self-explanation effect (Chi et al., 1989 Fergusson-Hessler & de Jong, 1990 Pirolli & Bielaczyc, 1989). Simplifying a bit, the effect shows that people l earn more effectively by canvas exercisings when they are careful to explain to themselves as many steps of the font as they can. Students who do not carefully explain worked out example steps do not perform as well on subsequent chores. Cascade models the potential learnedness mechanisms that cause this effect.I at once wish to apply the Cascade model to a new trouble domain and a new set of psychological data. Originally, Cascade was compose to solve problems in Newtonian physics, the domain used in Chi et al.s study. Since Cascade was first created additional psychological research has been done in other problem domains. Due to the versatility of Cascade, applying the Cascade model to other problem domains would be beneficial.
