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

Baseline reserve capacity in perceptual speed was assessed by repeating a computerized 32-item version of the Identical Pictures Test from the ETS three times (Ekstrom, French, Harman, & Derman, 1976; see also BASE Cognitive Test Battery).For each item a target geometrical figure was presented on the top half of the screen and five response alternatives in the lower half. Participants had to touch the picture in the bottom row that was identical to the target as fast as possible. For more detailed information about this test and its administration, see Lindenberger et al. (1993) or the "Intelligenz und Kognition" documentation at the Max Planck Institute for Human Development. The performance changes after test repetition (cognitive plasticity scores) provide estimate of participants' baseline reserve capacity.
