Comparing Behavioral and Self-Report Measures of Embodied Agents’ Social Presence in Immersive Virtual Environments
7th Annual International Workshop on Presence, 2004Co-Authors: Jeremy N. Bailenson, Aleksandar Dimov, Eyal Aharoni, Rosanna E. Guadagno, Arthur C Beall, Jim BlascovichAbstract:Recent work 1, 2, 3 has argued that subjective questionnaires may be ineffective at measuring copresence towards agents and avatars in immersive virtual environments (IVEs). The current work directly compares self-report and behavioral measures of copresence. In two studies, we measured the interpersonal distance between participants and either an embodied tutoring agent or an unfamiliar embodied agent as they walked through an IVE. We found that participants yielded more personal space to embodied tutors compared to other embodied agents in both studies. However, self-report measures of copresence, likability, status, or interest did not reveal any differences between embodied tutors and strangers. These findings suggest that nonverbal behavior may be a more sensitive measure of the copresence and general influence of embodied agents than self-report measures. While alternative explanations for these findings certainly exist, there are clearly strong advantages of using behavioral measures to study copresence as a compliment to other measures. Given that a large portion of current research evaluating collaborative environments utilizes self-report measures only, the current findings are particularly notable.

using subjective measures to detect variations of intrinsic cognitive load within problems
Learning and Instruction, 2006Co-Authors: Paul AyresAbstract:Abstract Cognitive load theorists have frequently used subjective measures of cognitive load to test the effectiveness of instructional procedures. This study sought to broaden the applications of subjective measures by testing their ability to detect variations in intrinsic cognitive load within tasks. In two experiments students were asked to complete algebraic problems and provide a subjective measure of cognitive load for each computation completed. By keeping extraneous and germane cognitive load constant, it was argued that changes in intrinsic cognitive load (element interactivity) were measured. Results showed that subjective measures were highly reliable, varied significantly within problems and correlated highly with errors. Evidence was also found that the subjective measures were influenced by the expertise of the learner and procedural errors.
