The levels of conversation model is used to explain how a conversation is constructed. The levels of conversation are:

– Low-level processes, which are all of the processes that are not cognitive, and that involve subconscious movements of bodily organs controlled by the central nervous system, such as moving the hand when writing.

– Linguistic levels, which range from phonology to syntax (the organization of sounds and the processes by which sentences are constructed).

– Semantic interpretation, which refers to the meaning of what has been said.

– Higher level processes, such as model construction (creating a model of the interlocutor and the situation).
