En psykologitext: "...there are two specific kinds of communication in the cognitive system: the propositional system, which functions through symbolic signals, and the non-propositional system, which functions through signals which do not denote anything, like hormones. Emotions are based on non-propositional communications, or “emotion signals”, which have important cognitive functions because they help the ac-tivation and development of these goals and, plans both in setting the whole system suddenly into a particular mode, and in maintaining it flexibly in that mode.
