Description of the executive function indices obtained from the random number generation test.

Working Memory Updating
Redundancy	Index reflecting the unbalance of response alternative frequencies in a sequence of generated numbers based on the theoretical frequencies of each digit
Coupon	Index of the mean number of responses given before all the alternative responses are used
Mean Repetition Gap	Index of the average quantity of digits between successive occurrences of the same number calculated for all digits throughout the whole sequence
Inhibition
Turning Point Index	Index of the similarity between the real frequencies of changes between ascending and descending series of numbers and their theoretical frequency in random responses
Runs	Index of variability of the number of digits in successive ascending or descending runs
Adjacency	Index of the relative frequency of pairs of adjacent ascending or descending numbers
