Questions on the nature of maturity

[Mourningfall]

What does it mean to mature in a psychological sense?

Is it to conform to societal standards of etiquette?
To abide by the moral alignments of our ancestors, by following guidelines set before birth?
To abide preset rules, laws, regulations, consitutions, legislations, codes and creeds?

Or is it simply the hormonal balance beyond adolescence?
Or perhaps it's the acquired ability to rationally judge whether or not an action is acceptable?

Do socioenvioronmental factors attribute to maturity?
If so, why so?

Does a persons perceived political correctness play a role in conscious gauging of maturity? how?
And why do humans strive to assimilate to political correctness? is it in hopes of acceptance? to be deemed mature?

Lastly, is it an inherent characteristic or is it a learned trait?

thoughts, speculations, theories or conjectures are all welcome.
