Personality changes during critical periods

Introversion later came to mean shyness,while an extrovert was someone outgoing.Today, an introvert is someone who finds alone time restorative,an extrovert draws energy from social interaction,and an ambivert falls somewhere between these two extremes.The notion of an innate, unchanging personality forms the basis of all these tests.But research increasingly suggests that personality shifts during key periods like our school years,or when we start working.Though certain features of a person behavior may remain relatively stable over time,others are malleable, moulded by our upbringing, life experiences, and age.
