	abstract = {Attention processes are the gateway to information acquisition and serve as a necessary foundation for higher-level cognitive functioning. The Virtual Reality Cognitive Performance Assessment Test (VRCPAT) focuses upon refined analysis of neurocognitive testing using a virtual environment to assess attentional processing and recall of targets delivered within the context of a virtual city and a virtual driving simulation. The 15 minute VRCPAT Attention Module and a 1.5 hour neuropsychological assessment were conducted with a sample of 12 healthy adults, between the ages of 21 and 36, that included equivalent distributions of men and women from ethnically diverse populations. No subjects had history of psychiatric or neurologic conditions. To examine scenario differences, one-way ANOVAs were performed, comparing attentional performance in simple stimulus presentations (Mean = 43.63; SD = 8.91) versus complex stimulus presentations (Mean = 34.63; SD = 6.86). The results indicated that the increase in stimulus complexity caused a significant decrease in performance on attentional tasks (F = 5.12; p = 0.04). To examine scenario differences, we compared attentional performance in low intensity (Mean = 40.01; SD = 4.06) versus high intensity (Mean = 9.25; SD = 3.70) presentations. The results indicated that the increase in stimulus intensity caused a significant decrease in performance on attentional tasks (t = 9.83; p = 0.01). Findings suggest that the increase in stimulus complexity and stimulus intensity within a virtual environment can manipulate performance on attentional tasks.},
