If you make a mistake, then the next sequence will be one number shorter. Usually, the trials are presented twice. To make it more interesting, gradually increase the Span, which starts out at 8, and change to Fast test speed. Previously established cutoff scores of 6 and 7 yielded a lower than acceptable specificity rate (6 = 85%; 7 = 77%), which corresponded to a false positive rate of 1422% respectively. The TOMM is a 50-item visual recognition task, which consists of two learning trials and an optional retention trial. In the nineteenth century, Herman Ebbinghaus (18501909; 1885/1964 cited in Richardson, 2007) was the first cognitive scientist to show how span could be used as an experimental paradigm to investigate memory and learning. However, more studies will need to be conducted to establish these cutoff scores with a greater level of confidence, as our sample size for each individual IQ group was quite small. Still, these cutoff scores (6, 7) have not been validated in adults with epilepsy. 2012;2012:829743. doi:10.1155/2012/829743.

Then, using previously established cutoff scores of 6 and 7 for RDS and <45 for Trial 2 of the TOMM, failure rates for both RDS and TOMM were established. The principal measure of chunking in the present experiment was a well- established one that reflects error probabilities associated with the learning of structured (chunkable) number sequences. This subtest mea- Further, when comparing rates of failures on the Test of Memory Malingering (TOMM; Tombaugh, 1996) and RDS, this cutoff score generated a 71% specificity value.

Gottfried Leibniz First and foremost digit span, along with reaction time, may be viewed as one of the two original paradigms used by experimental psychologists to investigate cognition. Ideally, PVTs should demonstrate strong sensitivity and specificity (Greve & Bianchini, 2004). This latter limitation is particularly important as epilepsy rarely occurs in isolation, and other conditions, such as psychiatric disorders, are known to impact performance on PVTs.
