What is Personality?

Personality refers to the individual differences in characteristic patterns of thinking, feeling, and behaving. It encompasses a range of traits that can influence how we interact with the world. Psychologists have developed various theories to explain personality, including:

  • Trait Theory

Understanding personality has practical applications in various fields, including:

  • Education
  • Workplace Dynamics
