Document Summary
Developmental changes in mean levels of personality traits. Based on 90 different studies that show the patterns of developmental change in personality across the life course [roberts et al] Average levels of conscientiousness, emotional stability, and the assertive aspects of extraversion tend to increase during adolescence, during young adulthood, and during early middle age. Average levels of the sociable and lively aspects of extraversion showed a slight decrease during young adulthood and another decrease toward the end of middle age. Openness to experience showed some moderate increases between adolescence and young adulthood, and then remained stable throughout adulthood before showing a decline during late middle age. Most people can be said to develop deeper maturity as they grow older. Why do these developmental changes occur: changes are due to biological processes of maturation. Important events and the changes in social roles that most people experience during their lives tend to have an influence on their personalities.
