Explain K. Warner Schaie's perspective on stages of development and discuss how it differs from Jean Piaget's approach.

What will be an ideal response?


A good answer would include the following key points:
- Developmental psychologist K. Warner Schaie focuses on how information is used during adulthood, rather than on changes in the acquisition of new information, as in Piaget's approach. The principle difference is an emphasis on the utility of information rather than the accumulation of information.
- Schaie proposed that adults' thinking follows a set pattern of stages:
- The acquisitive stage-the period before adulthood when information is gathered for future use
- The achieving stage-when young adults apply intelligence to long-term goals regarding family, careers, and contributions to society
- The responsible stage-when middle-aged adults are mainly concerned with their spouses, families, and careers
- The executive stage-further into middle adulthood, when many (but not all) people take a broader perspective, becoming concerned about the larger world
- The reintegrative stage-the period of late adulthood during which people focus on tasks that have personal meaning.
