Personality development is the development of the organized pattern of behaviors and attitudes that makes a person distinctive. Personality development occurs by the ongoing interaction of temperament , character, and environment.
Personality is what makes a person a unique person, and it is recognizable soon after birth. A child's personality has several components: temperament, environment, and character. Temperament is the set of genetically determined traits that determine the child's approach to the world and how the child learns about the world. There are no genes that specify personality traits, but some genes do control the development of the nervous system, which in turn controls behavior.
A second component of personality comes from adaptive patterns related to a child's specific environment. Most psychologists agree that these two factors—temperament and environment—influence the development of a person's personality the most. Temperament, with its dependence on genetic factors, is sometimes referred to as "nature," while the environmental factors are called "nurture."
While there is still controversy as to which factor ranks higher in affecting personality development, all experts agree that high-quality parenting plays a critical role in the development of a child's personality. When parents understand how their child responds to certain situations, they can anticipate issues that might be problematic for their child. They can prepare the child for the situation or in some cases they may avoid a potentially difficult situation altogether. Parents who know how to adapt their parenting approach to the particular temperament of their child can best provide guidance and ensure the successful development of their child's personality.
Finally, the third component of personality is character—the set of emotional, cognitive, and behavioral patterns learned from experience that determines how a person thinks, feels, and behaves. A person's character continues to evolve throughout life, although much depends on inborn traits and early experiences. Character is also dependent on a person's moral development .
In 1956, psychiatrist Erik Erikson provided an insightful description as to how personality develops based on his extensive experience in psychotherapy with children and adolescents from low, upper, and middle-class backgrounds. According to Erikson, the socialization process of an individual consists of eight phases, each one accompanied by a "psychosocial crisis" that must be solved if the person is to manage the next and subsequent phases satisfactorily. The stages significantly influence personality development, with five of them occurring during infancy, childhood, and adolescence .
