Human personality and its development are a complex and multifaceted concept. Its definition depends on who describes what drives people to behave and what it consists of. Personality differs from individual to individual. My personal theory of personality is called Interactive Personality Theory and includes four factors that interact with each other throughout an individual's life to create a flexible and adaptable personality. The basis of personality is the first genetic or hereditary factor on which the rest of the personality interacts and is based. The second personality factor is attachment to people, particularly to the primary caregiver early in life. The third interactive factor of personality is the effect of environmental and social influences on personality expression. Finally, the fourth personality factor is the ability over time to positively change one's personality and self-concept, to experience personality growth. Although personality is a complex and interactive system, it has a fundamental basis. The basis of each individual's personality is genetics or heredity. The DNA they acquire from both parents at conception is the fundamental element on which personality is built. The DNA that makes up the physical and mental structure of each person is not randomly selected through the physical act of conception. The Bible states that “for thou hast formed my inward parts; You knit me together in my mother's womb” (Psalm 139:13 New American Standard Bible). DNA allows individuals to have unique personalities and that's just the way it was meant to be. Heredity represents the stable portions of people's personalities throughout their lives as well as different temperaments... middle of paper... It also allows for the continued overall growth and adaptation of the personality throughout a human's life . This theory offers an optimistic approach that does not condemn personality to any single factor or influence. Works Cited Feist, J., Feist, G. J., & Roberts, T. (2013).
