Personality is a term that describes traits a person shows consistently at different times and in different situations. If we understand a person's personality we may be able 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."
