The Virtual Reality Paced Auditory Serial Addition Test (VR PASAT) was invented by Dr. Parsons to provide a virtual environment-based serial addition task that includes an aurally mediated alternative to visually mediated assessments of attentional processing.

There are two versions of the VR PASAT: 1) City Walk-Through; and 2) City Learning and Navigation Task. Both versions offer a virtual reality-based simulation with both high and low threat zones. The City Walk-Through represents a straightforward PASAT delivered over the COM. The City Learning and Navigation Task assesses the impact of threatening stimuli presented while subjects learn to navigate a three dimensional virtual environment.
