Document Summary

Personality development: continuities, consistencies and stabilities in people over time and the ways in which people change over time. 3 most important forms of stability are rank order stability, mean level stability and personality coherence: rank order stability: maintenance of individual position within a group. Highly motivated uni students are still motivated 10 years from now mean level stability but if they change mean level change/shift: personality coherence: changes in the manifestation of the trait . Ex. the manifestation of disagreeableness may differ across the life span, ranging from temper tantrums in infancy to being argumentative and having a short temper in adulthood. Even though the behaviours are different at different ages, they express the same trait: maintaining the rank order in relation to others but changing the manifestations of the trait, ex. Acts have changes but the overall trait (ex. dominance) have remained.
