Its capacity for creating, presenting, and manipulating dynamic three-dimensional (3D) objects and environments in a consistent manner enables the precise measurement of human interactive performance with these stimuli. VE spatial ability testing and training systems may provide ways to target cognitive processes beyond what exists with methods relying on 2D pencil and paper representations of 3D objects (or methods using actual real objects) that are typically found with traditional tools in this area. Traditional methods are often limited by poor depth, motion, and 3D cues needed for proper stimulus delivery. In addition they have limited capacity for the precise measurement of responses. VR offers the potential to address these variables in an ecologically valid manner (functional simulations) without the loss of experimental control common with naturalistic studies in this area relying on observational methods
