![]() This allows a more precise calculation of score, although it is not as prevalent in the literature.Īfter completing the test (which takes 7-8 minutes), you will get a score and the option for further testing. A variation suggested by Woods (2011) increases more quickly and will step up for each correct answer and step down (instead of stopping) for two errors. The traditional version as implemented in the Wechsler IQ test gives you two chances at each step and stops when you fail twice for the same span size. I also implemented an option to administer the test using different protocols. Prior research done on letters finds most people have a shorter (worse) letter span than digit span. This accesses memory differently and tests different working memory components.Īlthough digit span is the best known test, I also implemented options to use letters, colors and names as alternatives. After testing this 'forward span', you then are tested on 'backward span' which is a harder test where you have to say the sequence backwards. Memory span asks you to repeat back sequences that the tester says out loud, increasing the sequence length with each success to see the most you can do. Digit span is a very well standardized test used extensively in situations like mental status testing or IQ testing.
