The Dynamic Trust-based Resources (DyTR) system applies a dynamic notion of trust to ad hoc network resources. DyTR continuously assesses the trustworthiness of entities over time based on system events and controls network resources according to current levels of trust. For dynamic trust assessment, DyTR utilizes a socio-cognitive model of trust, a formal model of the essential concepts and ch...

AKIRA is an open-source framework for agent-based cognitive and socio-cognitive modeling and simulation. In this introductory paper we explain the underlying theoretical assumptions that lead to its central features, e.g. hybridism of the components, access to a common pool of resources, homeostasis of the system. In order to show the potentiality of AKIRA for cognitive modeling, we provide and...

Designing and supporting learning interactions that are genuinely engaging, meaningful and conceptually stimulating within online learning contexts remains a significant challenge in contemporary education. One currently popular approach which aims to address some key aspects of this problem, and motivational issues in particular, involves articulating interaction as a game. This Chapter, whils...

Decades of research have proven that many misconceptions of scientific notions are difficult to uproot even after intensive instructional interventions. In this paper we examine the role of argumentation and of explanation development in dyadic dialogues and their relation to consequential individual conceptual change. Two quantitative dialogue coding schemes were developed with different granu...

This paper proposes a formal approach of constructing shared mental models between computational improvisational agents (improv agents) and human interactors based on our socio-cognitive studies of human improvisers. Creating shared mental models helps improv agents co-create stories with each other and interactors in real-time interactive narrative experiences. The approach described here allo...

In recent years many corporations have become active on social networking sites (SNS). However, our understanding about how and why community members use corporate pages on SNS has not kept pace. In our study, we test a socio-cognitive model of brand page usage to investigate users’ incentives to consume and interact with corporations on Facebook. In order to do so, we conducted an online surve...

'Organisation' as a linguistic construct. " As the idea of an ultimate foundation for moral and political beliefs has become increasingly implausible, theorists have turned to 'discourse' to provide a basis on which to defend the legitimacy of social and political practices. The turn to discourse, which includes but is not limited to communicative ethics, is in part a move from a substantive to...

DyTR is an approach to trust that goes beyond traditional authentication-based techniques, in which the trustworthiness of entities in a system adapts over time based on system events. Using a socio-cognitive model of trust, DyTR provides an adaptive trustassessment methodology that allocates resources dynamically to an initial level of credentials, continually assesses trust, and adaptively al...

The paper aims at presenting an agent-based modeling exercise to illustrate how small differences in the cognitive properties of agents can generate very different macro social properties. We argue that it is not necessary to assume highly complicated cognitive architectures to introduce cognitive properties that matter for computational social science purposes. Our model is based on different ...
