Overview

Personality development represents the complex interplay between genetic predisposition and environmental factors that shape who we become as individuals. This dynamic process begins in early childhood and continues throughout the lifespan, influenced by both internal and external forces.

Foundational Theories

Psychodynamic Perspective

Sigmund Freud proposed that personality develops through psychosexual stages, while Erik Erikson expanded this into eight psychosocial stages spanning the entire lifetime. These stage theories emphasize how early experiences shape later personality outcomes.

Trait Theories

Modern understanding of personality development often centers on the Big Five personality traits:

• Openness to Experience
• Conscientiousness
• Extraversion
• Agreeableness
• Neuroticism

These traits show both stability and potential for change across the lifespan.
