The peak in performance across different abilities across age groups on the Wechsler Abbreviated Scales of Intelligence – second edition

This paper describes the pattern of median performance on the sub-tests of the Wechsler Abbreviated Scales of Intelligence 2nd edition across age groups 6-90 years from the test standardisation (N=2300). The median raw-score for: (a) block design peaks at age 25; (b) matrix reasoning sub-test...
