Conscious and Unconscious Parts of Language Generation
The thought process is not a fully conscious process. Some parts of it are conscious, while others are not. When we initially convert our thoughts into language, most words, phrases and sentences we use seem to emerge automatically. We become aware of them just before we speak them out. The reason for the same is that both VP and LB are involved in such conversion, where interactions or parts of the interactions that are processed by LB, i.e. preset interactions like repetitive, condition based and genetically programmed interactions, are not flagged as conscious, whereas rest of them are processed by VP, which are flagged as conscious (more under title How Interactions are Filtered).
Language and Hemispheric Lateralization
Based on the above, as most words and phrases used in everyday language and their usage rules and patterns are repetitive, and as repetitive interactions are processed by LB, they are processed in the left hemisphere (which is the basis of the observation that left hemisphere is dominant for production of language), which, as mentioned earlier, does not assign consciousness. As emphasis and intonation in speech are based on past data (i.e. past experiences) stored in the B-ROM database, they are processed in the right hemisphere (which is the basis of the observation that intonation and emphasis are processed in the right hemisphere), which assigns consciousness (more about lateralization on the mini-website brainduality.com).
Additional to (the intramural version of) intended communication like "go there", "pick up the cup", "I'll call you in the morning", intramural communication also contains attributes like trends, summaries, confidence levels, probability factors, emotion factors, etc. related to their respective parts of the interaction (if available), which I call "intramural attributes". Before verbalizing, such intramural attributes need to be processed with their respective parts, which enrich information about the interaction based on past interactions and also play a role in perception. The actual intended communication is only the end result of such processing.
When it is required for VP to deliberate on the content of intramural communication (e.g. to mull over) or if it becomes necessary to communicate such content externally, it does so by converting such end result of intramural attribute processing into extramural communication (explained in detail in Step 6b), which is analogous to the manager interpreting and conveying the conversation he is having with his owner to the manager of another company using the inter-company communication code he has learnt in the factory analogy.
As people only become aware of their thoughts just before verbalizing them (as explained earlier) and as the source of such communication is not known to them, it gives them the impression that thought processes are only associated with verbalization, unaware of the underlying intramural communication, as LB (which is not recognized as a functional component of mind by the current science) is a part of such communication, which does not assign consciousness. However, they are aware of the various effects LB produces, which are given different names like feeling, intuition, hunch, ESP, sixth sense, eureka moment, etc. (more under title Intuition, Hunch, etc.).
Intramural and Extramural Modes of Communication
Intramural mode of communication is suitable for both parallel and serial processing environment, but extramural mode of communication can only be run in serial processing environment.
As extramural communication is generated in VP, which is a serial processor, it is much slower than intramural communication, where VP communicates with LB, which is a parallel processor.
As a result of the optimizing aspect of the evolutionary process, intramural communication optimizes operations by offering maximum possible benefit of parallel processing to the interaction processing areas of the brain, even when half of them are limited by serial processing, whereas extramural communication optimizes goals by offering the flexibility of deliberation (explained in Step 6b) using past data and logical processing in a serial processing environment.
