A very nice summary of relevant scientific work is

Also, thinking fast and slow and other pop-sci books around decision making put a similar model forward. Personally, I am more focused on the active elements of consciousness and I try to use decision as the hermeneutics element rather than subject. Instead of looking at conscious beings like processors that model their environment and act upon that model, I am interested in the long term impact of decisions on behaviour and perception (i.e. my decisions impact the way I perceive the world.) Both models can co-exist. The article linked above has some very interesting links to much more researched models than my intuition.

Clarification: to reinforce my theory, I am wring about decisions when the author looks into emotions!
