There are two aspects of an individual's behavior that are central to the concept of personality- these are Consistency and Distinctiveness.
Behavioral personality theory, also known as behaviorism, is the study of human behavior that connects personality to one's environment.
A consistent person always behaves in the same way. He shows the same attitudes towards people or things or achieves the same level of success in something. Distinctiveness is the quality of being individual or easily distinguishable
Personality embraces moods, attitudes, and opinions and is most clearly expressed in interactions with other people. The Five Factor Model breaks personality down into five components: Agreeableness, Conscientiousness, Extraversion, Openness, and Stress Tolerance.
