1. Reflections on Two Major Development issues

2. Continuity & stages
Adults life does not progress through the fixed, predictable series of steps Erikson envisioned.
The human brain does not experience growth spurts during childhood and puberty that correspond roughly to Piaget’s stages.
Stage theories contribute a developmental perspective on the whole life span, by suggesting how people of one age think and act differently when they arrive at a later age.

3. Stability & change
The first two years of life provide a poor basis for a person’s eventual traits
Although delinquent children have elevated rates of work problems, substance abuse, and crime many troubled children have blossomed unto mature, successful adults
As people grow older, personality does stabilize
