been defined in various ways, including the level of embedding in a goal–subgoal hierarchy during problem-solving [6], the number of relations being simultaneously processed during reasoning [7], or the number of items held in working memory [8]. Reviews of RLPFC recruitment across multiple domains [2,9] show that activations are more frequent when the complexity of cognitive processing is high...

Knowledge sharing is a complex behavior. To show this complexity and ways of improving it, the intermediary role of attitudes, cognitive norms, and motivation seem to be important when considering the interaction between this complex behavior and personality traits. To show this relationship, a sample of 357 teachers from among all 570 high school teachers in Birjand was selected and then giv...

OBJECTIVES We examined the influence of postretirement leisure activity on longitudinal associations between work complexity in main lifetime occupation and trajectories of cognitive change before and after retirement. METHODS Information on complexity of work with data, people, and things, leisure activity participation in older adulthood, and four cognitive factors (verbal, spatial, memory,...

Title of Document: EFFECTS OF GROUP STATUS AND COGNITIVE APPRAISAL PRIME ON INTEGRATIVE COMPLEXITY IN A DECISION MAKING CONTEXT Katherine Lynn Van Allen, Doctor of Philosophy, 2009 Directed By: Professor Charles Stangor, Psychology Integrative complexity has been shown to influence information-processing and decision-making in different social situations. The present research assessed the effec...

Model complexity is key concern to any artificial learning system due its critical impact on generalization. However, EC research has only focused phenotype structural complexity for static problems. For sequential decision tasks, phenotypes that are very similar in structure, can produce radically different behaviors, and the trade-off between fitness and complexity in this context is not clea...

An increasing need for shared communication in disparate domains as well as the production of increasingly dynamic, large-scale systems has always been at the heart of the practice of systems engineering. As a branch of general systems theory, systems engineering was developed to address practical considerations posed by diverse organizations, environments and cultures within which systems are ...

Cognitive linguistics gives the most inclusive, consistent description of how language is organized, used and learned to date. Cognitive linguistics contains a great number of concepts that are useful to second language learners.  If-clauses in English, on the other hand, remain intriguing for foreign language learners to struggle with, due to their intrinsic intricacies. EFL grammar books are ...

ions provide powerful simplifications of a controller's working mental model. Changes in strategies, including the use of strategies taking advantage of a controller's ability to manipulate the operational environment, provide additional opportunities for cognitive complexity reduction.

Until quite recently, it was taken for granted in AI-and cognitive science more broadlythat activity resulted from the creation and execution of plans. In 1985, several researchers, including myself, independently realized that plans and planning are not necessary-or necessarily useful-in activity. Since this time, a number of alternatives have been proposed. In this issue of AI Magazine, Matth...
