A biologically inspired cognitive architecture is described which uses navigation maps (i.e., spatial locations of objects) as its main data elements. The are also used to represent higher-level concepts well direct operations perform on other maps. Incoming sensory information mapped local then in turn matched with the closest multisensory maps, and onto a best-matched map. Enhancements feedba...

Cognitive impairment is consistently reported in children treated for brain tumors, particularly in the categories of processing speed, memory, and attention. Although tumor site, hydrocephalus, chemotherapy, and cranial radiation therapy (CRT) are all associated with poorer function, CRT predicts the greatest deficits. There is a particularly high correlation between CRT and slowed information...

Graffiti and ‘maker’ cultures use technology in ways that reveal specific effects of the urban environment. Researchers have paid little attention to how these cognitive artifacts – artificial devices designed to serve a representational function – are invented, acquired, or transmitted across individuals or generations, especially in groups outside of accepted criterion. This paper investigate...

COGENT is a design environment for modelling cognitive processes and systems. It permits psychologists to construct and test information-processing models of cognition based on traditional box/arrow diagrams. COGENT provides a graphical model editor together with a set of standard types of cognitive module based on familiar theoretical constructs from psychological theory. Models are constructe...

Basic cognitive functions, such as the abilities to activate, represent, maintain, focus and process information, decline with age. A paradigm shift towards cross-level conceptions is needed in order to obtain an integrative understanding of cognitive aging phenomena that cuts across neural, information-processing, and behavioral levels. We review empirical data at these different levels, and c...
