Personality formation refers to the development of an individual's characteristic patterns of thinking, feeling, and behaving. This process is influenced by a combination of genetic factors, environmental experiences, and social interactions. Key theories, such as those proposed by Sigmund Freud and Carl Jung, emphasize the role of early childhood experiences and unconscious motivations in shaping personality. Additionally, personality can be shaped by cultural influences, family dynamics, and life events. The Big Five personality traits—openness, conscientiousness, extraversion, agreeableness, and neuroticism—are commonly used to describe and assess personality. Understanding these factors helps in recognizing the complexity of human behavior and individual differences.
