The research explaining the human emotional aspect of the sociability is linked to the urge of looking for safety and the level of acceptance. It is worth noting, however, that the brain and nervous systems operate in bi-directional interconnectivity with circuits found in the body and emptiness. Such circuits were thought to be connected to the hypothalamus along with other brain regions controlling the evaluation of such parameters as safety. In other words, safety is about predictability of results while acceptance is about predictability of support from the surrounding people. All these factors are interrelated, which in turn makes feel secure and accepted, and these two emotions are important for happiness and self-satisfaction.
