Perception Of Shared Visual Space: Establishing Common Ground In Real And Virtual Environments, Jonathan W. Kelly, Andrew C. Beall, Jack M. Loomis

Jonathan W. Kelly

When people have visual access to the same space, judgments of this shared visual space (shared vista) can facilitate communication and collaboration. This study establishes baseline performance on a shared vista task in real environments and draws comparisons with performance in visually immersive virtual environments. Participants indicated which parts of the scene were visible to an assistant or avatar (simulated person used in virtual environments) and which parts were occluded by a nearby building. Errors increased with increasing distance between the participant and the assistant out to 15 m, and error patterns were similar between real and virtual environments. This …

Psychophysiological Reactivity To Traumatic And Abandonment Scripts In Borderline Personality And Posttraumatic Stress Disorders: A Preliminary Report, Christian G. Schmahl, Bernet M. Elzinga, Ulrich W. Ebner, Timothy Simms, Charles A. Sanislow, Eric Vermetten, Thomas H. Mcglashan, J. Douglas Bremner

Charles A. Sanislow, Ph.D.

Borderline personality disorder (BPD) is a highly prevalent and disabling condition linked to early stressors including traumatic abuse and abandonment. While much work has addressed traumatic events in childhood, little is known about the biological sequelae of BPD including how this disorder may be differentiated from other stressrelated disorders such as posttraumatic stress disorder (PTSD). The purpose of this study was to investigate psychophysiological effects of different types of stressful reminders in BPD and in PTSD. Psychophysiological measures including heart rate, skin conductance responses, systolic and diastolic blood pressure in response to standardized neutral scripts, and personalized scripts of traumatic …

Judgments Of Exocentric Direction In Large-Scale Space, Jonathan W. Kelly, Jack M. Loomis, Andrew C. Beall

Jonathan W. Kelly

Judgments of exocentric direction are quite common, especially when judging where others are looking or pointing. To investigate these judgments in large-scale space, observers were shown two targets in a large open field and were asked to judge the exocentric direction specified by the targets. The targets ranged in egocentric distance from 5 to 20 m with target-to-target angular separations of 45 8 ,90 8 , and 135 8 . Observers judged exocentric direction using two methods: (i) by judging which point on a distant fence appeared collinear with the two targets, and (ii) by orienting their body in a …
