Excerpt
The development of intellectual competence in childhood and
adolescence follows a fairly uniform path, with new stages of competence
and differentiation of functioning occurring within a relatively
narrow age band. By contrast, there are widely divergent individual
trajectories over the life course of adult intelligence. However,
over the 50-year course of the SLS (Schaie 1996, 2005),

conclusions on a number of core questions:
