4.9 Introduction to Personality Theories

What is personality?

Personality refers to an individual's characteristic, relatively stable patterns of thinking, feeling, and behaving across time and situations. Psychologists have developed multiple theoretical approaches to explain how personality forms and why people differ, including psychoanalytic, humanistic, trait, social-cognitive, and biological perspectives.

Freud's psychoanalytic view

Sigmund Freud's psychoanalytic theory proposed personality arises from unconscious conflicts among the id (primitive desires), ego (rational mediator), and superego (moral conscience). Freud emphasized early childhood experiences, defense mechanisms, and psychosexual stages as shaping adult personality — though this theory is largely untestable and criticized for lacking scientific rigor.

Humanistic perspective

Humanistic theorists like Carl Rogers and Abraham Maslow rejected Freud's focus on conflict, instead emphasizing free will, growth, and self-actualization. Rogers highlighted the importance of unconditional positive regard and a healthy self-concept, arguing people thrive when their real self and ideal self align.
