Emotions are not consciously controlled. The part of the brain that deals with emotions is the limbic system. It’s thought that this part of the brain evolved fairly early-on in human history, making it quite primitive. This explains why an emotional response is often quite straightforward, but very powerful: you want to cry, or run away, or shout. It’s because these responses are based around the need to survive.
Emotions are strongly linked to memory and experience. If something bad has previously happened, it affects your emotional response to the same stimulus is likely to be strong.
Children feel emotion but can’t necessarily reason. Emotions are also closely linked to values: an emotional response could tell you that one of your key values has been challenged. Understanding this link to memory and values gives you the key to managing your emotional response. Your emotional responses don’t necessarily have much to do with the current situation, or to reason, but you can overcome them with reason and by being aware of your reactions.
