Administering the test forward and backward assesses short-term memory. When the backward version of the test is given, it also measures working memory. Another goal of this study is to examine the relationship between RDS and overall intellectual functioning, as prior work (Welsh et al., 2012) has shown that RDS is related to IQ in children with epilepsy.

Accordingly, the National Academy of Neuropsychology (Bush et al., 2005) and the American Academy of Clinical Neuropsychology (Heilbronner et al., 2009) have issued strong statements urging neuropsychologists to incorporate performance validity tests (PVTs) in every evaluation, regardless of the referral question (Schroeder, Twumasi-Ankrah, Baade, & Marshall, 2012; Sharland & Gfeller, 2007), as these instruments provide insight into whether an examinees scores are likely reflective of their actual level of cognitive functioning or the result of them not putting forth maximum effort (Constantinou, Bauer, Ashendorf, Fisher, & McCaffrey, 2005). Conversely, a cutoff score of 6 produced a more acceptable false positive rate (8%) and specificity rate (92%) for this IQ group. Reliable Digit Span (RDS) is a heavily researched symptom validity test with a recent literature review yielding more than 20 studies ranging in dates from 1994 to 2011. However, memory span can be expanded dramatically in one case to 80 digits by learning a sophisticated mnemonic system of recoding rules by which substrings of 5 to 10 digits are translated into one new chunk.

Additionally, general intellectual functioning, as measured by IQ, has been found to be compromised within this clinical population (Baxendale, McGrath, & Thompson, 2014). Findings also revealed that RDS scores were significantly positively correlated with measures of IQ, as well as with those related to attention. Speed does not matter. . The remaining had either normal neuroimaging or neuroimaging data was unavailable.

For example, if the proposed measure is a questionnaire, the score on the measure should indicate the . When recoding strategies were used to remember digit sequences, increased activation was observed in the lateral prefrontal and posterior parietal cortex. Marshall cuts the lead with a massive three-pointer, and Clark adds one for good measure. The average person can hold a set of about 7 digits in his/her working memory at any given time.

Prior to conducting failure rates for each IQ group, Pearson correlations were carried out to examine the extent to which RDS and TOMM scores were related to IQ and attention within our sample. Although only moderately sensitive, Digit Span scores are likely to have good utility in identifying noncredible performance in relatively high-functioning older children and adolescents. A common prefrontal-parietal network for mnemonic and mathematical recoding strategies within working memory. Bethesda, MD 20894, Web Policies Specifically, a cutoff score of 7 yielded an unacceptably high false positive rate (13%) for adults with epilepsy that had average IQ and above.
