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.)

  • Default testing mode for consistant presentation and comaparable results
  • Highly customizable custom mode for specialized uses
  • Digits forward and backward
  • Presents stimuli in auditory, visual, or audiovisual format
  • Multiple sequence generation algorithms that prevent "easy" sequences
  • Generates stimuli for human presentation
  • Saves results or stimuli to text file
  • Prints results or stimuli
  • May uses log and config files to store settings and back-up data
  • Fractional score based on a linear model of where accuracy drops below 50%
