Background: Understanding factors that contribute to successful cognitive aging has become increasingly important as a growing portion of the population lives to very old age. Our research has focused on different patterns of cognitive aging by using electrophysiologic and behavioral measures. Previously, we demonstrated (e.g., NeuroImage, 2008; 39(1)) that cognitively high-functioning younger-...

BACKGROUND Cognitive impairment is an established feature of schizophrenia. However, little is known about its relationship to the structural and functional brain abnormalities that characterise the disorder. Aims To identify structural and/or functional brain abnormalities associated with schizophrenic cognitive impairment. METHOD We carried out structural magnetic resonance imaging (MRI) an...

In this study, the authors investigated the relationship between the cognitive status of normal adults and age-related changes in attention to novel and target events. Old, middle-age, and young subjects, divided into cognitively high and cognitively average performing groups, viewed repetitive standard stimuli, infrequent target stimuli, and unique novel visual stimuli. Subjects controlled vie...

COMMUNICATIONS OF THE ACM March 1999/Vol. 42, No. 3 71 The first approach focuses on forms of communication, requirements for consistent collaboration, planning of coordinated behaviors to achieve collaborative goals, extensions to logics of action and belief for multiple agents, and types of emergent phenomena when many agents interact, for instance, taking routing decisions on a telecommunica...

English and Italian differ a great deal in their respective repertoires of spatial particles (an important subset of which are prepositions), an area which seems to be quite problematic in foreign language learning. Most current EFL textbooks and didactic grammars tend to provide partial and idiosyncratic cross-linguistic descriptions of such items, while the majority of dictionaries’ accounts ...

We built Smart Home applications for the Cognitively Impaired population. We have chosen to work with an existing framework, OSGi, which allows us to develop specific applications more quickly. We use a combination of traditional testing and formal verification to insure these applications will cause no harm to the cognitively impaired users of our systems. This paper will focus on our results ...

A prominent model suggests that individuals to the right of the political spectrum are more cognitively rigid and less tolerant of ambiguity than individuals to the left. On the basis of this model, we predicted that a psychological mechanism linked to the resolution of visual ambiguity--perceptual bias--would be linked to political attitude. Perceptual bias causes western individuals to favour...

Information Visualization is concerned with the art and technology of designing and implementing highly interactive, computer supported tools for knowledge discovery in large non-spatial databases. Information Visualization displays, also known as information spaces or graphic spatializations, differ from ordinary data visualization and geovisualization in that they may be explored as if they r...
