The correct answer is Personality traits
“Personality” is a very easy concept for most people to understand: it's what you do, “you”. It is a set of characteristics that encompasses all the traits, qualities, defects and peculiarities that distinguish you from all others.
For psychology, however, the definition of personality is a little more elaborate than that. The concept understood by some researchers may not be identical to which classifies the personality as "the individual differences in the characteristic patterns of thought, sensation and behavior".
Any change in that definition can influence how a person's personality is identified and understood.
