A person with a defensive personality may feel as if they are being attacked and to cope with this they need to defend their choice of words and actions when dealing with others individuals. My younger sister, Carlee, has a defensive personality. We have the same mother, but different fathers. This made us grow in different situations. She moved around a lot, going from my father's house, to our mother's house, and to her father's house. He had no fixed place where he could call it “home”. Overall, Carlee is a good girl, she listens and doesn't argue too much. However, as brothers usually do, there are arguments between us. She will become overly defensive and extremely furious very easily. Overreacts to the smallest comments and actions. To discuss his defensive trait, I will discuss the psychological personality trait theories of Lawrence Kohlberg and Erik Erikson. Erickson, a psychologist who studies the psychological stages of development, proposed that personal development was directly influenced by social experiences. One of the main elements of his theory of staged development is the development of ego identity, or the conscious sense of self that develops through social interaction. Conflict at every stage is a central point of Erikson's theory. Each stage of development focuses on conflicts that must be successfully resolved to develop a particular psychological quality. In his theory, each stage builds on the previous stages, and therefore, the inability to master specific qualities will affect a person's future development. I believe that by associating the theories with my sister's behavior, this would occur in phase four. There were stressful times with his mother and father, and there... in the middle of the paper... n individual. The result can also be the same, even if there is variability between personalities. Both Kohlberg and Erikson have strong theories on how personalities are formed at an early age with a direct focus on parents. Overall, the role of adults, whether they are parents or not, plays a huge role in shaping our personalities as children. Adults need to understand that when they have children and the marriage breaks up, the focus needs to be on the children. We need to give children an image that informs them about the correct ways to behave and defend themselves from others. If Carlee had grown up in a different environment, in a stable home, she would have had a different personality. He wouldn't get angry as often and would understand better how to behave if he didn't agree with what others have to say.
