At some point in my life, at a young age or as a resident in a nursing home, the question of who I am will arise. It is a convoluted set of thoughts and feelings that a person goes through before finding an answer. Some people may even experience cognitive dissonance when trying to explain different stages of life, while others will be comfortable reacting instantly with minimal cognition. By going through this process and defining “who am I” and the individual is more confronted with the perception of others. Where does this lead, when presented with the opinion of others, and on what is it based? The response from outside sources is primarily based on the perspective regarding an individual's personality. A person's distinctive characteristics and qualities are one way of defining personality. According to Feist and Feist (2009), personality is described as a set of relatively permanent traits and unique characteristics that provide both consistency and individuality to a person's behavior. These traits are the precursor to behavior according to individuality and consistent behavior throughout life. Although a person can claim that traits are a genetic predisposition to certain characteristics, the models in which these are characterized are different. Every person's anatomy, intelligence and temperament are different and everyone has a unique personality, different from their parents, grandparents and any other individual on this planet. Personality theorists may disagree, however. Theorists in this branch of psychology have not agreed on a specific definition of personality, because one theory is the beginning of another. Nevertheless, the different theoretical approaches...... middle of article......theories of nature and nurture as precursors of personality can enable an individual to achieve a clear perspective of its evolution. However, in the study of personality, it is very important to understand the different theoretical approaches in its field. It is important for the same reason that no two people are the same, nor are personalities; and for the same reason why personality theorists differ in describing the concept and nature of humanity.
