ABSTRACT
E xecutive functions represent the farthest reaches of human nature. Whereas many neuropsychological skills of interest in rehabilitation (atten-tion, visual-spatial perception, ne-motor dexterity, memory, and perhaps even language) are shared with other mammalian species, Homo sapiens appears unique in possessing the mental tools that allow for consciousness and the dynamic shaping of environments. The neurological substrate for this executive regulation of complex cognition and social behavior is strongly, but not exclusively, that of the frontal lobes (Mayer & Schwartz, 1993).
