It is how a person responds to stimulation. Extroverts require a lot of stimulation to feel alive. Introverts require a small amount of stimulation to feel alive. Otherwise, too much stimulation affect them negatively.
According to studies by psychologists Hans Eysenck, introverts require less stimulation from the world in order to be awake and alert than extroverts do. Extrovert’s brains run on an energy spending nervous system, whereas introverts’ brains run on an energy-conserving nervous system.
Introverts prefer to use “acetylcholine” or in simple terms the parasympathetic side of the nervous system, which is nicknamed the ‘throttle down’ or ‘rest-and-digest’ side. When we engage the parasympathetic side, our body conserves energy, and we withdraw from the outer environment. Our muscle relaxes; energy is stored; food is metabolized; pupils constrict to limit incoming light, and our heart rate and blood pressure lower.
Extroverts prefer to use “Dopamine” or simpler terms the sympathetic side, known as the ‘full throttle’ or ‘flight, flight, or freeze’ system.
Introverts’ brains aren’t as strongly rewarded for gambling or taking risks as extroverts’ brains are. Extroverts’ brains responded with more pleasure to positive gambling results according to scientists. Introverts feel less excitement from surprise or risk.
The Introvert’s brain treats interactions with people at the same intensity level that it treats encounters with inanimate objects. Introverts usually have an active dialogue with themselves and most of the time walk around with many thoughts in their minds.
Solitude allows introverts to recharge. It is a state or situation of being alone, frees your mind from distractions and no outside voices could influence your ideas.
When it comes to workplace culture, Introverts prefer close space offices and tasks that do not require much interaction with other people. Open space offices and open collaborations mean more stimulation.
Leadership roles are usually offered to extroverted employees. Extrovert leaders perform better with passive terms. Introvert leaders perform better with proactive teams. Cooperation between introverts and extroverts is not impossible. Small or even complicated problems can be solved when the balance between solitude and cooperation is found.
Introversion and Shyness
Shyness and Introversion are commonly perceived as the same. These two are quite alike, but they are actually different. You can be Shy and an introvert at the same time, on the other hand, you can also be Shy and extroverted.
Shy: Fear of negative social judgment
Introvert: Preference for environments with low stimulation.
