Transaction Process ExamplesActive person- environment transaction

Person seeks out compatible environments and avoids incompatible ones

Aggressive person goes to bar where fights are frequent; introvert avoids social gatherings

Reactive person- environment transaction

Different people respond differently to the same situation

Extravert finds party enjoyable; introvert finds same party unbearable

Evocative person- environment transaction

Aspects of an individual’s personality leads to behavior that changes the situations he or she experiences

Conscientious person tells group “it’s time to get to work”; disagreeable person starts argument over minor matter

Personality Development

• Cohort effects: may contribute to age differences in cross-sectional studies

• Longitudinal studies– Similar findings to cross-sectional studies– People become more socially dominant,

agreeable, conscientious, and emotionally stable; and self-esteem (up to age 50) and ego development increase

– Confirms the maturity principle
