Step-by-step explanation:
The four paradigms, or main schools of thought, discussed in the lecture that study personality are Behaviorism, Humanism, Biological Approaches, and Trait Theorists.
Behaviorism is a perspective that sees human behavior as determined by a combination of genetics and environment. Humanism emphasizes personal control, intentionality, and the potential for good that is innate to all humans. Biological approaches focus on the biological factors that influence personality, such as genetics and brain processes. Trait theorists study and classify personality traits and individual differences.
