Interesting; can you elaborate? Also could you clarify what you mean by changes that are "not always visual"? How would non-visual information exist in a purely visual medium?
If I were a researcher, my contrived test of this would be to simply have people recreate drawings of "static" objects, and have others recreate drawings of objects implied to be in motion.
Other non-visual information would be emotions. The shape of eyes and mouth lines are highly critical to passing emotion. I suspect that people's interpretation of emotion directly impacts how strong the emotional representation of those parts of the face would be drawn. For example if a test subject is told to draw the face of a model in front of them, but they are told the person is experiencing an emotion, I hypothesize that the group of people who are told the person is happy would more frequently bias their interpretation of the eyes, eyebrows, and corners of the mouth towards a "happy" representation than those who are told the person is experiencing great inner turmoil.
To be clear though, I'm not saying we only draw based on non-visual information. I'm saying the sum total of all vectors has an influence on the drawing. Colors, in my opinion, have as much of an impact as edges. And it would be interesting to compare the drawings of a person with less common color sensitivities to more common color sensitivities.
