Personality is the combination of thoughts, emotions and behaviors that makes you unique. It's the way you view, understand and relate to the outside world, as well as how you see yourself. Personality forms during childhood, shaped through an interaction of two factors:
- Inherited tendencies, or your genes. These are aspects of your personality passed on to you by your parents, such as shyness or having a happy outlook. This is sometimes called your temperament. It's the "nature" part of the nature vs. nurture debate.
- Environment, or your life situations. This is the surroundings you grew up in, events that occurred, and relationships with family members and others. It includes such things as the type of parenting you had, whether loving or abusive. This is the "nurture" part of the nature vs. nurture debate.
Personality disorders are thought to be caused by a combination of these genetic and environmental influences. You may have a genetic vulnerability to developing a personality disorder and your life situation may trigger the actual development of a personality disorder.
