Personality development is the relatively enduring pattern of the thoughts, feelings, and behaviors that distinguish individuals from one another.The dominant view in the field of personality psychology today holds that personality emerges early and continues to change in meaningful ways throughout the lifespan.

 

Adult personality traits are believed to have a basis in infant temperament, meaning that individual differences in disposition and behavior appear early in life, possibly even before language or conscious self-representation develop.The Five Factor Model of personality has been found to map onto dimensions of childhood temperament,[4] suggesting that individual differences in levels of the “big five” personality traits (neuroticism, extraversion, openness to experience, agreeableness, and conscientiousness) are present from young ages.
