Who are some famous African Sculpture artists and what is their most famous works?

Have there been studies pertaining to the differences in visual perception and spatial recognition (colors, shapes, perspective) between visual artists (drawing, painting sculpture, photography) and those without these "gifts"?

• I am interested in how artists who create their art in visual mediums may differ from "non-artists" in terms of how they perceive the world visually. In my discussions with artists, it seems (anecdotally) that the way they perceive colors, shapes and the relationships between these is different from "the rest of us". Where I may see a green wall, an artist may perceive many shades of green, gray, and other colors  across the surface. If I draw a face, I may draw outlines of the major features where an artist may focus on the contrast and shading between features. Is this a learned behavior, i.e. something that can be obtained through attention to detail and awareness of certain "rules" of art and creating visual representations of seen or imagined objects or scenes, or is this something that is part of the inherent wiring of one's brain and not an ability that can be obtained if you do not already posess it?

• Answer:

  It is something you develop through looking and studying. The more you know the content and context of an artwork, thru studying the art history, you can develop those qualities. We are all artists.
