The modafinil group performed better on several tasks, such as the "digit span" test, in which subjects are asked to repeat increasingly longer strings of numbers forward, then backward.

Working memory was assessed using the digit span test backward from WAIS.
Children's attention skills were tested with the digit span test while teachers rated their behavior.
Attention was assessed using the digit span test forward from the Wechsler adult intelligence scale (WAIS) (Wechsler 2003).
We further show a correlation with amount of practice within the group of professionals as well as a correlation with a forward digit span test.
Additionally digit span test (DST), disability measured by the HD-activity of daily living-score (HD-ADL) and depression according to the Beck Depression Inventory were evaluated.
Data were suggestive of positive associations between serum concentration of lithium and working memory and attention as shown by the main effects in the regressions for lithium (digit span test backward [β = 0.29, p = 0.039, Fig. 1c]; digit span test forward [β = 0.24, p = 0.087]).
Daily patient assessments using the MMSE, DRS-R-98, and Digit Span test [assessment of attention, range 0 (no attention) to 42 (good attention)] were used to enable the DSM-IV and CAM diagnoses and assess delirium severity [23].
This was shown by significant main effects in the regressions for valproate (digit span test backward [β = −0.28, p = 0.043]; CVLT subscore short delay free recall [β = −0.30, p = 0.043]) (Fig. 1a, b).
Working memory function was measured using the Digit Span test of the Wechsler Adult Intelligence Scale [25].
