The correct answer is: Personality is significantly shaped by the reinforcements and consequences outside of the organism.
The main idea of the behavioral perspective on personality is that human behavior is shaped by diverse consequences or reinforcements, which may be administered by someone else like parents, friends, teachers, etc. or just naturally happen in the environment; in both cases they will affect the individual's behavior; therefore, since each person has its own history of contingencies, each person will develope a unique range of behaviors as well.
