Reasoning:
General Information

The cognitive test battery in BASE contains 14 tests measuring five intellectual abilities (perceptual speed, reasoning, memory, knowledge fluency). At the 5th measurement point 8 out of the original 14 tests were included in the assessment.

Reasoning was measured by the following three tests:
a) Figural Analogies (16 items, computerized version). Some of the items were adapted from a German version of the Lorge-Thorndike Intelligence tests for children (Heller, Gaedike, & Weinläder, 1976; cf. Thorndike, Hagen, & Lorge, 1954-68).
b) Letter Series (16 items, Thurstone, 1958). Participants had to complete series of five letters (e.g., c e g i k ?) by choosing the correct of five answer alternatives.
c) Practical Problems: 12 items containing everyday problems. Some of them were adapted from the ETS Basic Skills Test (Educational Testing Service, 1977).
The test scores for (a), (b), and (c) correspond to the number of correct answers. Time constraints are low.

For more detailed information about the procedures, see Lindenberger, Mayr, & Kliegl, (1993), Lindenberger & Baltes, 1997 or the "Intelligenz und Kognition" documentation at the Max Planck Institute for Human Development.
