From my poster presentation at Toward a science of Consciousness Conference
The poster is very large and is available as PNG (6.1m) or PDF (573k)
and here is a graphic model showing how the functon of awareness is a special case of representation: PNG or PDF.
Below is a presentation of notes and argument for how representation making is the key problem of consciousness and how representation making may be instantiated in a computational system.
The section "#02 Awareness and representation illustrated" is mostly contained on the left half of the poster
