At Time 4, cognitive plasticity (Baltes, 1987; Kliegl & Baltes, 1987) in several domains was estimated by assessing performance changes after test repetitions. The "Cognitive Plasticity Test Battery" (compiled by Neher, M. M. Baltes, and Lindenberger) contained tests measuring three intellectual abilities (perceptual speed, reasoning, and memory).

Plasticity in reasoning was assessed by repeating the ADEPT Figural Relations Test, Subtest 3 (Matrices), Form A and B, two times (Plemons & Willis, 1975; Plemons, Willis, & Baltes, 1978). The 16 items consisted of geometrical figures and were presented in the format "A relates to B in the same way as C relates to ...?". Participants chose out of five geometrical figures that one, which showed an analogous relation. For more detailed information about this test and its administration, see "Documentation of the BASE assessment instruments at Time 4" at the Max Planck Institute for Human Development. The performance changes after test repetition (cognitive plasticity scores) provide estimates of participants' baseline reserve capacity.
