Assessment of brain activities in immersive environments.

The primary goal of this study was to establish an objective baseline for subjects who participated in a study in an immersed environment created for the virtual reality therapy (VRT) situation. Since the effects of VRT on the subjects treated for neurosis have traditionally been measured by subjective measurements, there is a need to include objective measures. This will improve and validate the effectiveness of VRT. Fifteen college students participated in this study. Specifically, the researchers measured the activity of the subjects' brainwaves in response to the VRT using EEG technology. The preliminary data indicated that, in most cases, subjects had a decline in brain wave activity between what is deemed a normal / baseline brain activity and the brainwave activity recorded when they were when they were connected to the virtual reality equipment and under influence of an immersive scene. In rare instances, there were some subjects that showed extreme increases in brain activities. In addition, the data indicated that, in most cases, subjects are more relaxed while under the immersive influence with respect to brain activities than those that are not.

Virtual reality combats test anxiety: a case study report.

This pilot study is the first known in-depth case study of the effectiveness of virtual reality therapy (VRT) as a treatment for Test Anxiety (TA). The subject of the study was a 28-year-old male, whose anxiety and avoidance behavior was interfering with his normal academic activities. For treatment, he was placed in a virtual classroom and later in a virtual auditorium. The subject was exposed to six moderately increasing in difficulty level virtual situations. The subject rated each situation for discomfort. As a simple measure of anxiety, a modified version of the Subjective Units of Disturbance (SUD) scale was used every five minutes during exposure. This case study showed VRT to be an effective treatment method for reducing self-reported TA. Symptoms experienced by the subject during VRT sessions were just as real to the subject as actual test taking and general TA situations. They included increased heart rate, mild dizziness, and headaches. This case study of TA indicates that VRT may be used as an effective treatment method for reducing self-reported anxiety and improving the performance of subject(s) who suffer from TA.
