Test | Description | Adaptation of |
---|---|---|
Memory span I: Digit span, unsorted (‘Zahlen merken – unsortiert’) | Rows of single-digit numbers are presented (each 1 second); the numbers must be reproduced immediately afterwards | WAIS-IV [35], task Digit Span |
Memory span II: Digit span, ascending (‘Zahlen merken – aufsteigend’) | Like Memory span I; numbers must be reproduced in ascending order | WAIS-IV [35], task Digit Span |
Processing speed I: Number Comparison (‘Zahlen vergleichen’) | Comparison of two single-digit numbers separated by a horizontal line (participants should react if same number) | Pattern Comparison\Letter Comparison [36] |
Processing speed II: Symbol count (‘Symbole zählen’) | Counting a target symbol in a pool as fast as possible | SKT [37], task ‘counting symbols’ |
Processing speed III: Numerical stroop task (‘numerischer Stroop-Test’) | Two single-digit numbers are presented in different sizes (congruent/incongruent mixed); number with higher value must be clicked as fast as possible | |
Short term memory I: Free recall (‘Wortliste – Erinnern’) | 12 objects have to be named; afterwards shown for 1 minute; some tests later, the objects must be remembered | SKT [37], task ‘delayed recall’ |
Short term memory II: Cued recall (‘Wortliste – erkennen’) | The objects from Short term memory I must be selected from a selection of 16 objects | SKT [37], task ‘recognition recall’ |
Logical reasoning: Matrices Test (‘Matrizentest’) | In a (2×2 or 3×3) matrix of symbols, the bottom right symbol is missing; the composition rule has to be understood, and the correct symbol must be selected | Raven Standard Progressive Matrices [40] |
