1

initiation: average of the z scores corresponding to the completion time (corrected for the error rate in each test) in the Trail Making test A and Stroop naming and reading subtests;

2

inhibition: errors in the interference subtest - errors in the naming subtest of the Stroop test;

3

flexibility: average of the z scores corresponding to perseveration in the Card Sorting and Trail Making test B;

4

generation: average of the z scores corresponding to the two fluency tests;

5

deduction: average of the z scores corresponding to categories achieved in the Card Sorting test and errors in the Brixton test;

6

coordination: the z scores corresponding to the mu dual task index;

7

planning: the z scores corresponding to the six elements task (Godefroy et al., 2010).
