Bounded rationality and heterogeneity in economic dynamic models

Via Scoop.itBounded Rationality and Beyond

Economic theory has always faced the issue of how to model human behavior, in particular how to model individual decision making in an interactive framework. Assuming that an economic actor, e.g. an individual consumer or a firm, wants to make the decision in his best interest and that he is capable of making this judgment, the two approaches that are currently in use rely on different levels of the decision maker’s rationality. The approach of neoclassical economics, which we will refer to as rational, can be summarized using two requirements. First, the decision maker is assumed to be able to choose the alternative that maximizes utility or profit, given his beliefs about the economic environment and the actions of the other actors in the economy.

The cognitive neuroscience of creativity – Psychonomic Bulletin & Review, Volume 11, Number 6 – SpringerLink

Via Scoop.itBounded Rationality and Beyond

This article outlines a framework of creativity based on functional neuroanatomy. Recent advances in the field of cognitive neuroscience have identified distinct brain circuits that are involved in specific higher brain functions. To date, these findings have not been applied to research on creativity. It is proposed that there are four basic types of creative insights, each mediated by a distinctive neural circuit.

By definition, creative insights occur in consciousness. Given the view that the working memory buffer of the prefrontal cortex holds the content of consciousness, each of the four distinctive neural loops terminates there. When creativity is the result of deliberate control, as opposed to spontaneous generation, the prefrontal cortex also instigates the creative process. Both processing modes, deliberate and spontaneous, can guide neural computation in structures that contribute emotional content and in
structures that provide cognitive analysis, yielding the four basic types of creativity. Supportive evidence from psychological, cognitive, and neuroscientific studies is presented and integrated in this article. The new theoretical framework systematizes the interaction between knowledge and creative thinking, and how the nature of this relationship changes as a function of domain and age. Implications for the arts and sciences are briefly discussed.

ingentaconnect Declarative and Procedural Working Memory: Common Principles, Com…

Via Scoop.itBounded Rationality and Beyond

Working memory is often described as a system for simultaneous storage and processing. Much research – and most measures of working-memory capacity – focus on the storage component only, that is, people’s ability to recall or recognize items after short retention intervals. The mechanisms of processing information are studied in a separate research tradition, concerned with the selection and control of actions in simple choice situations, dual-task constellations, or task-switching setups. both research traditions investigate performance based on representations that are temporarily maintained in an active, highly accessible state, and constrained by capacity limits. In this article an integrated theoretical framework of declarative and procedural working memory is presented that relates the two domains of research to each other. Declarative working memory is proposed to hold representations available for processing (including recall and recognition), whereas procedural working memory holds representations that control processing (i. e., task sets, stimulus-response mappings, and executive control settings). The framework motivates two hypotheses: Declarative and procedural working memory have separate capacity limits, and they operate by analogous principles. The framework also suggests a new characterization of executive functions as the subset of processes governed by procedural working memory that has as its output a change in the conditions of operation of the working-memory system.
