General intelligence is a construct consisting of different intellectual abilities. The cognitive test battery in BASE contains 14 tests measuring five intellectual abilities. At the 5th measurement point 8 out of the original 14 tests were included in the assessment.
In this documentation, each is described separately:
Knowledge, Perceptual Speed, Fluency, Memory, Reasoning.

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

Note:
According to the design, names for Time 1 have the prefix c1, names for Time 3 have the prefix c3,
names for Time 4 have the prefix c4, names for Time 5 have the prefix c5,
names for Time 6 have the prefix c6, and names for Time 7 have the prefix c7.
