In trying to understand where to focus my research, it looks like it's going to be around the area of phosphenes, and what comes after phosphenes, some type of compound phosphenes, or phosphene maps.
I am convinced that somewhere along the developmental path of cognition in humans, there is an area that displays evidence of protoglyphs. I think it is after phosphene expression and before mandala expression. What I call protoglyphs may very well turn out to be phosphene maps.
Here's a proposed order for graphical cognitive development:
1. Phosphene expression (age 2)
2. Unintentional abstraction- phosphene maps (age 2-3)
3. Shape execution -- mandala first, then squares, triangles (age 3-4)
4. Shapes in settings
5. Cartoons in Settings (on the way to the figurative) (age 5-8)
6. Literal, figurative 'life-like' representations in a setting (age 8-?)
7. Deliberate abstraction in drawings and intellect (age 11+)
The idea here is that first, objects are learned, and then the objects are shown in a setting with relationships. First, phosphenes are expressed, and then phosphenes in settings with positions that represent relationships. This dynamic parallels the development of human children, even now, in that first the letters of the alphabet are learned, then words, then sentences. First, the components, and then rules to arrange the components.
The area I intend to focus on is the early paleolithic art of non-representational patterns. After reading an article published by Bednarik (R. G. Bednarik, The Earliest Evidence of Paleoart, Rock Art Research, 2003, Vol. 20, No. 2, pp 89-135), my first thought were that these patterns may represent:
1. Maps of Land/Areas - for shared discussion with others
2. Counting/Record-keeping - perhaps of large animals killed, or victories (notches in a belt)
3. Ownership - identification/clan symbols
Another assumption that I'm making is that learning must come before graphical expression is possible. In other words, something must be known and understood before it can be expressed. What this means cognitively, is that the knowledge, or knowing, was already in place for paleolithic humans, before it was expressed. The advantage of something written down or drawn is that it is unambiguous. How often do we hear, even today, "Put it in writing." Verbal knowledge can be easily misunderstood, and then mistranslated. The game of Chinese Whispers is a great example of how a simple phrase can unintentionally evolve and change as it is communicated from one human to the next.
Something else to think about when the meaning of phosphene maps is interpreted. Humans long ago had the same basic needs that we have today. Food, shelter, community...(a quick look at A. Maslow's hierarchy of needs can perhaps give us an indication of the 'first concerns' of paleolithic people). Issues of land occupation, record-keeping or counting of victories achieved, and ownership are all key parts of life today, just as I think they probably were 42,000 years ago.
