The purpose of this study was to propose a new way of representing the structure of expectancy-value attitude and to investigate the implications of its representation. Expectancyvalue attitude was represented as a cognitive network of vertically and horizontally interconnected judgements about product attributes, using a structural equation modeling methodology. Results suggested that a struct...

In the networked world of today, global virtual teams (GVT) are becoming a common form of work structure. The geographic dispersion in GVT has led to members' high reliance on electronic communication media for collaboration and task performance. With advancements in ICT, the range of media to choose from has increased considerably. This complicates the process of selection and usage of media t...

Cognitive processing applies to a single human being, yet most key social processes are organized in collectives, and connecting them is not a simple task. I review the basic ways in which social and behavioral scientists have tried to link the individual with the system, illustrating the progress that has been made in this endeavor. We are closer than we ever have been to producing a behaviora...

To build a data-integration system, the application designer must specify a mediated schema and supply the descriptions of data sources. A source description contains a source schema that describes the content of the source, and a mapping between the corresponding elements of the source schema and the mediated schema. Manually constructing these mappings is both labor-intensive and error-prone,...

A crucial feature of intelligent agents is their being proactive not only reactive, their anticipatory representations i.e., their ability to deal with the future by mental representations or specific forms of learning. For guiding and orienting the action a representation of the future and more precisely a representation of future effects and of intermediate results of the action is needed. Ha...

Our previous research demonstrated how a cognitive architecture can inform the design of instructions. This abstract describes continuing research into instructional representations in both human instruction and cognitive architectures. In our past study (Taatgen et. al, submitted), two different forms of instructions were devised. These were dubbed “list-style” and “operator-style.” As the nam...

This paper describes some functionalities and features of the Maryland Virtual Patient (MVP) environment. MVP models the process of disease progression, diagnosis and treatment in virtual patients who are endowed with a “body,” a simulation of their physiological and pathological processes, and a “mind,” a set of capabilities of perception, reasoning and action that allow the virtual patient to...

The emerging research interest on neural oscillation in neuroscience has resulted in an ever-increasing number of studies on various cognitive and neuro-developmental phenomena. There is, now, evidence linking brain physiological descriptions with certain phenotypes in normal and atypical behavior, involving neural oscillation. Case studies include brain disorders, such as autism and schizophre...

In this paper, we present two necessary and sufficient theoretical notions that have to be taken into account for an ITS to dynamically build relevant student models: non-monotonicity, and hypothetical reasoning. These notions issue from the following empirical observations: the student’s cognitive state evolves in time, he/she may have contradictions in mind, and to diagnose his/her knowledge ...
