To perform automated digit span tests to evaluate on working memory function, especially in cognitive / neuro research. Hope to reduce practice effects and eliminate the need to use clinical assessments in research settings. Requires Java 7 or newer. Note that this is a research tool, and was not intended (and not evaluated) for clinical assessment.
FINAL VERSION: If you want more features, download the source and hack it yourself.
Ethics Note: Since this does not diagnose anything, label results as normal/abnormal, contain pre-made stimuli or anything from a published assessment, and neither tries to teach the task nor seems to do so (as some commercial products claim to do) I believe it is safe and acceptable in the public domain. (If this were not true, it wouldn't be here.)
Operating System: All 32-bit MS Windows (95/98/NT/2000/XP/Vista/7), POSIX (Linux,BSD,Solaris etc..), BSD, OS Independent
