The unconscious processing seems to be simpler than the conscious one. It includes a whole range of neural processing from the automatic reflex of some simple animals such as the E. coli to automatic actions taken by human. Actually conscious and unconscious processing is similar; they are different versions of the same thing, presumably using at least some of the same neural equipments. The consciously performed actions of the beginner are a stumbling version of the more unconscious actions of the skilled performer. Conscious and unconscious forms blend into each other; there is no hard dividing line. Conscious processing can be summarized as the combination of unconscious processing with feeling or thought - sometimes more, sometimes less, depending on the level of detail or complexity. The brain is constantly trying to automate processes, thereby dispelling them from consciousness; in this way, its work will be completed faster, more effectively and at a lower metabolic level. Consciousness, on the other hand, is slow, subject to error and expensive.
The figure presents a modern view of the conscious. It divides the conscious and subconscious thought into four divisions (controllers). While the Pavlovian controller is the brain's autopilot, the other three control systems (see more detail in the diagrams, and
brain components) combine both kind of thought to achieve the best possible outcome depending on the level of uncertainty about the situation you are in. In this model, subconscious and conscious thoughts are more like equal partners than competitors. The two work together to evaluate all the available information whether consciously or subconsciously perceived. Our behaviour is often driven by more than one of the four controllers. This is especially true when we are learning something new where the balance between ignorance and experience changes. Importantly, the subconscious isn't the dumb cousin of the conscious, but rather a cousin with different skills.
