What accounts for personality change across the lifespan? (4 perspectives)
- Biological-Essentialist- The basis of the FFM model; Personality is determined by genetic/biological factors; Research shows that genetics account for 40-60% of personality trait differences
- Contextualist- Personality arises through interaction with the environment
- Corresponsive Principle- People experience life events that reflect their personality traits; once these events occur, they further affect people’s personalities
ex: ambitious & confident people are attracted to demanding jobs & demanding jobs need dedication & drive leading to more ambition & confidence
Personality stability is influenced by the active choices that we make. It’s about an interaction between one’s personality & the experiences that people choose - Interactional- considers both the person and the environment in the development; idea that it’s both nature & nurture
