Evolutionary approach to investigations of cognitive systems is analyzed. Modeling of cognitive evolution (a study of evolution of animal cognitive features) is considered. Backgrounds of models of cognitive evolution that are developed in the area of research “Adaptive behavior” are outlined. Our initial models of cognitive evolution investigations are described. The sketch program for future ...

This paper presents the approach that we adopted to design a cooperative environment to assist the technological innovation process in an extended firm. This approach involved two main steps. The first step consisted of obtaining a description of the requirements and a cognitive model of the collaborative work carried out by the members of the project. This was used to build a cooperation space...

This chapter presents a comprehensive set of spectrum occupancy models specifically envisaged for the analysis, design and simulation of cognitive radio systems. The presented models have been proven to accurately capture and reproduce the statistical properties of spectrum occupancy patterns in real systems. The chapter begins with the description of various time-dimension modeling approaches ...

Human cognitive modeling techniques and related software tools have been widely used by researchers and practitioners to evaluate the effectiveness of user interface (UI) designs and related human performance. However, they are rarely used in the cyber security field despite the fact that human factors have been recognized as a key element for cyber security systems. For a cyber security system...

Making a realistic update of a user model based on evidence in the environment is not an easy task, unless a great deal of time with a large variety of users is available. Creating general categories of users that behave in a certain way is important for any kind of user model. To obtain such a broad classification we need to understand general factors that influence user behavior. We describe ...

The Advanced Identity Representation (AIR) Project is a new interdisciplinary approach to the problem of designing identity technologies to enable imaginative selfrepresentations for users by implementing dynamic social identity models grounded in computing and cognitive science. AIR Project research develops models of social computational identity (e.g., characters, avatars, and social network...

The perception of semantic similarity derives from distinct processes of comparison and integration. A dual process model of conceptual combination claims that attributive combination (e.g., umbrella tree) entails comparison, while relational combination (e.g., pancake spatula) requires integration. The present research uses similarity as a test of this dual process model. Participants (N = 168...

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,...

This paper describes a model of learning stages called OCTR. Learning under OCTR advances gradually as the degree of social context increases. Furthermore, OCTR can also serve as a framework for describing the cognitive development and motivation of students, categorizing many existing teaching strategies, and better understanding how to introduce meta-cognition and attitude in systems for educ...

This study examines the impact of integrating worked examples into a Cognitive Tutor for genetics problem solving, and whether a genetics process modeling task can help prepare students for explaining worked examples and solving problems. Students participated in one of four conditions in which they engaged in either: (1) process modeling followed by interleaved worked examples and problem solv...
