The research objective was to evaluate cerebral blood flow velocity's (BFV) sensitivity to performance changes in a multitasking setting and to examine resulting constraints on multitasking. The research used a Transcranial Doppler Sonography (TCD) unit and multitask environment simulation. The tasks represented the diverse nature of the future military environment and included visual tracking, auditory monitoring, and more complex cognitive tasks requiring mental manipulations and memory. Participants completed four tasks simultaneously but with varying priority. BFV and multitask performance were measured. Results showed that BFV changed during training and paralleled a performance change. BFV was not sensitive to changes in task load during multitasking. We did show behavioral consequences to multitasking, specifically when transitioning between tasks. The data suggest that BFV may not be the most direct neurophysiological method for measuring complex cognitive performance; however, the use of this type of portable and relatively low-cost methodology should be pursued further.

This paper describes a study on the sense of presence and task performance in a virtual environment as affected by copresence (one subject working alone versus two subjects working as partners), level of control (control of movement and control of navigation through the virtual environment), and head tracking. Twenty subjects navigated through six versions of a virtual environment and were asked to identify changes in locations of objects within the environment. After each trial, subjects completed a questionnaire designed to assess their level of presence within the virtual environment. Results indicated that collaboration did not increase the sense of presence in the virtual environment, but did improve the quality of the experience in the virtual environment. Level of control did not affect the sense of presence, but subjects did prefer to control both movement and navigation. Head tracking did not affect the sense of presence, but did contribute to the spatial realism of the virtual environment. Task performance was affected by the presence of another individual, by head tracking, and by level of control, with subjects performing significantly more poorly when they were both alone and without control and head tracking. In addition, a factor analysis indicated that questions designed to assess the subjects' experience in the virtual environment could be grouped into three factors: (1) presence in the virtual environment, (2) quality of the virtual environment, and (3) task difficulty.
