Distributed teams can carry out critical tasks with appropriate decision support technologies. The architecture and detailed design of a Web-based GDSS, called TeamSpirit, are discussed to address the challenges of building a Web-based GDSS. A series of empirical studies are reported to assess the effectiveness of TeamSpirit in supporting distributed group problem solving when in-person facilit...

In this paper we explore the extension of 2D pointing facilitation techniques to 3D object selection. We discuss what problems must be faced when adapting such techniques to 3D interaction on VR applications, and we propose two strategies to adapt the expanding targets approach to the 3D realm, either by dynamically scaling potential targets or by using depth-sorting to guarantee that potential...

Execution of tasks in which information rapidly changes its relevance employs both excitatory and inhibitory top-down control. This assertion is derived from empirical data and computational cognitive modeling of a screen-based Stroop task. Empirical data showing both within-trial (interference and facilitation) and between-trial (negative priming) effects are presented. A computational cogniti...

This paper explores the potential learning benefits of 3D Learning Environments (3DLEs). It presents definitions of key terms and analyses the learner-computer interactions facilitated by 3DLEs, in order to identifj! the unique characteristics of such environments It is argued that the most important potential contribution of 3DLEs to conceptual understanding is through facilitation of spatial ...

Abstract We examined the effect of word stress position on bilingual auditory cognate processing. Turkish–Dutch early bilinguals who are dominant in their L2 (Dutch) performed an lexical decision task Turkish or Dutch. While Dutch has variable stress, with a tendency for penultimate is mostly predictable and usually falls ultimate syllable. Our tasks included two-syllable cognates both language...

Collinear facilitation of contrast detection of achromatic stimuli has been studied over the past decade by different groups. We measured collinear facilitation of chromatic contrast detection under equal-luminance (photometric quantity) and under isoluminance (minimum motion technique) conditions, as two different controls. The facilitation was tested for chromatic contrast detection of a fove...

Although facilitation and leadership behaviors are thought to be critical to the success of virtual teams, little research has been done to examine the impact of facilitation behaviors on virtual teams. In order to fill this knowledge gap, this study empirically examines the impact of external facilitation behaviors on virtual team interactions and outcomes. Contrary to common belief, our findi...

Distributed group facilitation techniques are becoming a necessity because many of the face-toface facilitation techniques are no longer suitable in a distributed environment. Although the concept of distributed group facilitation has been proposed a decade ago, few distributed facilitation techniques have been successfully employed in the real world. We propose a new method of automating distr...

BACKGROUND Facilitation is a powerful approach to support practice change. The purpose of this study is to better understand the facilitation roles exercised by both external facilitators and interprofessional facilitation teams to foster the implementation of change. Building on Dogherty et al.'s taxonomy of facilitation activities, this study uses an organizational development lens to identif...

introduction: preparation of neuromuscular system prior to performing motor skills affects the learning of motor skills. the present study was conducted to investigate the effects of proprioceptive neuromuscular facilitation (pnf) on limb coordination and accuracy in dart throwing skill. methods: thirty two male students were randomly selected as study sample. based on the pretest scores, the p...
