I believe most schools of personality theory assume that core sense of self becomes ingrained by the ages of 4 or 5. That’d include the introversion/extroversion ‘nature’; which is probably complex shades of grey, rather than simple black and white.
However, there are ‘nurture’ issues that can arise during life that could influence a more naturally extroverted personality to act/behave in a very introverted manner (and vice-versa).
Typically, these could include emotional damages or physiological factors, leading to a sense of isolation, dislocation or social withdrawal – which aren’t inherent personality, or healthy, but rather a result of trauma or illness.
An emotionally healthy personality recognizes the amount of personal space it requires, AT A GIVEN TIME, to maintain a balanced equilibrium – both socializing and seeking solitude as necessary to maintain a personal contentment and happiness in life.
In contrast, an emotionally unhealthy personality can polarize too heavily on either socializing or solitude as a misguided coping mechanism that will fail to bring contentment and happiness.
In the worst cases, this can lead to an unhealthy cycle, whereby the individual constantly chases the wrong solution to resolve the unhappiness and discontent that the same solution builds within them.
