You need to name those parameters in a sentence only because it's linear, in a graph they can correspond to unnamed nodes. Abstractions can have structure, and their applicability can depend on how their structure matches the current scene. If you retain in a scene graph only relations you mention, that'd be your abstraction.
I'm not sure if you mean a graph in the sense of nodes and edges, or in a visual sense.
If the former, any implementation requires that the edges identify or link somehow to the appropriate nodes -- so how is this done in humans and what experiments reveal it? If the later, the location in space of the node in the abstract graph is effectively it's identity -- are you suggesting that human abstraction is always visual, and if so what experimental evidence is there?
I don't mean to include or exclude your theory of abstraction, but the question is whether you know of experiments that shed light on this area.
