Further considerations in the neuropsychology of art
Introduction A natural observational setting for neuropsychology and neuroscience is afforded in the artist's studio. Artists often produce on their own volition, their productions reflecting the mind in the brain outside carefully controlled conditions of a scientific laboratory. Yet no specific neuropsychological tests have been designed to assess art following brain damage in artists. This is largely due to the fact that only a few of the equivalents of "words" and "grammar" in art are known, and relatively few such artists can constitute the standardization sample. The alphabetical primitives in visual art consist of forms, shapes, and patterns represented with various angles, perspective lines, convergence, vanishing points, overlap, grayscale gradations, canonical views, disembedding, texture, medium, colors, shadows, and edges. These examples do not all have ready interpretations within existing neuropsychological tools or models. In addition, the significance of the whole composition lies in the culture in which the art is produced and is experienced. A method for separating this from alphabetical art primitives remains to be worked out.
