The importance of understanding Model B comes from realizing that each function is based around an information element/aspect that correlates to a specific component of observed reality. Model B is not a deviation from Model A, but a form of Model A worked out to completion.
Bukalov defined it as a 16 component full spectrum model, in which he then started to coagulate the model using the concept of dimensionality. To understand Model B, one must understand exactly what each section of model A does, as understanding the process of information metabolism is required in order to understand the “in-out” scheming of Model B. So that is where I'll start, with model A.
Imagine an iceberg in the water. Half of the iceberg above, half of the iceberg below. What is above the water are the conscious functions, they are visible overt processes. What is below the water is the unconscious functions, hidden shadow processes that mirror the conscious processes. Then you have another dichotomy, the outside of the iceberg v.s the inside of the iceberg. The outside of the iceberg is the strong functions, are those that result sectors of the personality. The weak functions exist inside, they are the purpose sectors of the personality, herein lies the desires of the dominant functions. The important thing to understand about model A is it is based on information metabolism, meaning that all of the functions are interlinked, meaning they are apart of the same process on different levels of the psyche. You don't sweep your floor with your role function, you don't eat cake with your super-id functions. Model A is simply a way that information is categorized on different levels perception.
Ego functions(Valued, Strong, Conscious): This is the dominant process, the vent so to speak. This is how a person processes information, how they think, how the exist, how they interact with the world.
Super-Ego: (Devalued, Weak, Conscious): This is the conscious antithetical function to the ego. It serves as a conscious motivator for what not to do, balancing out the ego. This type of information is typically viewed with contempt, as the person is trying to eliminate it from their processes. The goal is to run out of this.
Super Id: (Valued, Weak, Unconscious): This is the unconscious motivator function. This is what the person wants to attain underneath, this functions represents completion of the Ego function, the full perspective.
Id: (Strong, Devalued, Unconscious): This is the unconscious base function. It always exists as a perfect mirror the ego function, as this is the pure primal function of the psyche. For example, if the ego function was designed around cleaning a room(hypothetical scenario), the Id functions would see all the messy aspects, it is the natural unconscious perspective.
