Syllabus: How Do We Adapt as We Grow Older?
Connect goals and resources through selection, optimization, and compensation. Compare this broad developmental use of compensation with the narrower neural definition, and notice the role of assistance and cultural resources.
A question to consider. How could someone preserve participation in a valued activity without preserving exactly the same performance, method, or level of independence?
Why this reading
Development can involve choosing goals, improving the means to pursue them, and finding alternatives when those means change. Baltes places these processes within a larger argument about biological capacities and cultural resources across life.
Before you read
Ontogeny means an individual's development. Selection concerns goals; optimization concerns means; compensation concerns alternative means when losses or constraints arise. The framework distinguishes growth, maintenance, and regulation of loss. What counts as a gain depends on the criterion used.
Read for
- Reconstruct the argument linking biological limits and the need for cultural resources.
- Distinguish selection, optimization, and compensation in the examples without assuming that every adjustment is deliberate.
- Examine how support from others can change the resources available for pursuing a goal.
Consider afterwards
- Someone keeps participating in a valued activity by changing its pace and using assistance. Which parts of the framework apply, and what evidence would show whether the adjustment serves that person's goals?
Editorial context
This theoretical article connects evolutionary claims, lifespan observations, and a general adaptation framework. Its illustrations are not experimental tests of the whole account. Historical estimates and age boundaries are not current individual forecasts. The argument invites scrutiny of both its biological premises and the values used to judge gains and losses; requiring assistance does not establish failure to develop.
