The Kohs Block Design Task is one of the most well understood and well described neuropsychological tests of visual spatial reasoning, used widely for intelligence testing, with early sensitivity to brain injury. Comprehensive models of cognitive subprocesses entailed in its execution have been developed. Task variables critical to various aspects of execution have also been identified. As one of the most well understood and characterized neuropsychological tests it is an excellent candidate for application in functional neuroimaging. We report a realistic 3D virtual version of the task for fMRI based on computer game interface design methods.
