The Human Computer Interaction community is beginning to wrestle with the challenges of effective interaction design for groups collaborating in 3 dimensional virtual worlds. Understanding of the requirements and design processes necessary to support these new technologies is still emerging. While the gaming community has developed heuristics for game(More)
Online learning in K-12 and higher education has been growing rapidly, and open source software has the potential to improve the quality of e-learning. This chapter describes how FOSS enables turning e-learning from a potentially restrictive and narrow framing of the education experience to an emergent and social experience. The chapter will identify(More)
This paper describes a preliminary study which attempted to apply learning analytics methods to usage data generated by students with autism spectrum disorders using iSocial, a collaborative, three-dimensional virtual learning environment. Drawing from similar methods in the area of learning and content management systems, the work presented in this paper(More)
BACKGROUND Major depressive disorder has been associated with abnormal resting-state functional connectivity (FC), especially in cognitive processing and emotional regulation networks. Although studies have found abnormal FC in regions of the default mode network (DMN), no study has investigated the FC of specific regions within the anterior DMN based on(More)
INTRODUCTION Use of electroconvulsive therapy (ECT) is limited by cognitive disturbance. Focal electrically-administered seizure therapy (FEAST) is designed to initiate focal seizures in the prefrontal cortex. To date, no studies have documented the effects of FEAST on regional cerebral blood flow (rCBF). METHODS A 72 year old depressed man underwent(More)

Eliminating the controllability of a noxious stimulus may induce a learned helplessness (LH) that resembles aspects of depression and post-traumatic stress disorder (PTSD). This study examined whether repetitive transcranial magnetic stimulation (rTMS) of the left dorsolateral prefrontal cortex (DLPFC) promotes resilience in an aversive stimulus model of(More)
