McCrae and Costa

McCrae and Costa are psychologists best known for developing the Five Factor Model of personality, also known as the Big Five. This model identifies five key traits that describe human personality: openness (creativity and curiosity), conscientiousness (dependability and organization), extraversion (sociability and outgoingness), agreeableness (compassion and cooperation), and neuroticism (emotional instability and anxiety). Their research helps to understand how these traits influence behavior, relationships, and overall well-being, providing a comprehensive framework for studying personality in various contexts, such as psychology, business, and education.
