Several historical trends are enumerated that preceded contemporary discuss
ions concerning the development of personality dimensions, personality type
s, and the person as a self-organising goal-oriented agent. For description
of personality across the life course, the big-five personality dimensions
are related to similar dimensions in temperament. For a proper understandi
ng of the person as an active agent in personality development, a model for
personality functioning is proposed that integrates elements of descriptiv
e research on personality and temperament with theoretical views on persona
lity and temperament functioning, that is, Block and Block's (1980) views o
n the curvilinear relation between ego-control and ego-resiliency and Rothb
art's (1989) ideas on the distinction between reactivity and self-regulatio
n. Typological personality studies are related to this model for personalit
y functioning. Finally, personality development across the life course is r
elated to the development of four developmental domains (i.e., interpersona
l, achievement, self-concept, and creative domains).
