Interpersonal distance (IPD) is a simple social regulation metric which is altered in autism. We performed a stop-distance paradigm to evaluate IPD regulation in autism spectrum disorder (ASD) and control groups in a real versus a virtual environment mimicking in detail the real one. We found a bimodal pattern of IPDs only in ASD. Both groups…

Looking at human communication from the perspective of semiotics extends our view beyond verbal language to consider other sign systems and meaning-making resources. Those include gestures, body language, images, and sounds. From this perspective, the communicative process expands from individual mental processes of verbalizing to include features…

On an enactivist conception of cognition, the unit of explanation is not just the brain, not just the body, and not just the environment, but the body--brain--environment understood as a dynamically coupled structure or gestalt. On this view, referencing Viktor von Weizsäcker's metaphor of the gestalt circle (Gestaltkreis), the brain is not in the…

In this paper we examine the transferability of the Jigsaw and Fishbowl collaborative learning techniques to the Second Life platform. Our aim is to assess the applicability of Second Life for collaborative learning by developing virtual tools and metaphors and exploiting the representational richness of this novel medium. In order to enhance the…

The Internet usage has been increasing among persons in the worldwide. This situation highlights that the number of potential distance learners has been increasing in the Internet society. Besides, the terms and concepts of the Internet environments become to be spread out in this society like virtual reality. It is also possible to explain the…

This paper examines the effective deployment of conversational agents in virtual worlds from the perspective of researchers/practitioners in cognitive psychology, computing science, learning technologies and engineering. From a cognitive perspective, the major challenge lies in the coordination and management of the various channels of information…

Immersive collaborative virtual environments (CVEs) are simulations in which geographically separated individuals interact in a shared, three-dimensional, digital space using immersive virtual environment technology. Unlike videoconference technology, which transmits direct video streams, immersive CVEs accurately track movements of interactants…
