Stage model of lifespan development - psych notes

Schaie’s   (1977- 78) stage model of lifespan development:

1.  Acquisitive Stage :  Children and adolescents acquire information for own sake.

2.  Achieving Stage:     Late teens and twenties, use knowledge to be competent and independent.

3.  Responsible Stage:  Late 30’s to early 60’s – Knowledge to accomplish goals, solve practical problems associated with their work and family responsibilities.

4.  Executive Stage:  30’s and 40’s – achieving and responsible stages overlap and are custodians of social life.

5.  Re-integrative Stage:  Older adults – concentration on what has personal meaning.
