Overview

Characteristics

• The comprehensive, intensive examination of a heterogeneous, locally representative sample of 516 old people whose long-term progress is traced across 7 further measurement sessions
• A focus on the very old (70 to over 100)
• A broad-based multidisciplinary approach whose goal is to generate a reference data set spanning a broad range of different functional areas
• The investigation of changes associated with aging and death in the very old

Theoretical Orientations

• Differential aging
• Continuity vs. discontinuity
• Plasticity and reserve capacity (range and limits)
• Aging as a systemic phenomenon

Prototypical Questions

1. Are individual age differences predictable on the basis of life history data?
2. How large are age differences within domains, and which direction do they take?
3. How are the transdisciplinary relationships across different domains?
4. How do characteristics, processes, links between them change in the course of aging?

Note that the fourth question can only be answered with longitudinal data following individuals as they age.

BASE Data: Usage by external scientists

The data from all occasions of measurement are collected in a well-documented central database. Information about access to their documentation and the application process for usage of BASE data can be found here. more
