Personality
These traits are shown at different times and in different situations.  Understanding someone’s personality may allow you to predict their behavior in many situations.  Predictability makes it possible to explain and understand behavior.  A person's personality can often suggest their internal thoughts, feelings, and behaviors.  Intrapersonal functioning is a term used to describe the stable processes that underlie these thoughts, feelings, and behaviors. Gordon Allport defined personality as a "dynamic organization inside a person, of psychophysical systems that create the person's characteristic patterns of behavior, thoughts and feelings."
