#Difficulties on digit span wais professional
Professional tests (I was not given exact scores): Here are some more results since you seem interested: If you know any good tests for short term memory online I'm willing to try. And I kept shuffling the order of things for backwards and sequencing tests. Of course I failed at this, since the numbers never even entered my short term memory.
I can clearly remember losing my focus and thinking "Should I cluster the numbers in groups of 2? 3? Or is that cheating?" while the psychologist was listing the digits. To be honest I believe this might be a due to a flaw in WAIS III, since ADHD affects focus and auditory input, and the digit span tasks were based on auditory input. Your results are fascinating to me, given such high intellectual abilities despite the working memory just a little above average. :) In my opinion, these are the most reliable tests right after WAIS. So this is not a solid confirmation that working memory is strongly correlated with timed matrix reasoning tasks.īut if nothing else, the study at least showed that Reven's tests are very reliable and have an excellent ability to accurately discriminate those in the >95th percentile. Although here we are talking about only 6 people out of 200 who managed to achieve such a high score on Raven’s tests. A study I conducted on a sample of about 200 randomly selected people found that among those who scored high on Raven's 2/Raven's APM set II, the average digit span task was 8.2 digits successfully recalled. Performance validity assessment processing speed psychometrics working memory.That's interesting. Overall, results indicated that embedded WAIS-IV WMI and PSI are useful embedded PVTs in conditions in which cognitive impairment is not expected however, these embedded PVTs demonstrated questionable utility among patients with cognitive impairment due to poor sensitivity, if adequate specificity is maintained, suggesting limited efficacy among patients with cognitive impairment due to risk of false-positive classification. Further, notably reduced sensitivities of 16-28% (≥91% specificity) were found for the remaining significant indices. In contrast, for patients with cognitive impairment, Digit Span, Arithmetic, WMI, and Coding were nonsignificant, and AUCs of.66-.67. When the sample was subdivided by cognitive impairment status, AUCs of.68-.87 and 36-56% sensitivity (≥87% specificity) for detecting invalidity at cut-scores that maximized accuracy were found among those without cognitive impairment. Among the patients with valid performance, 54% were cognitively impaired, whereas 46% were cognitively unimpaired.Īmong the overall sample, performance on WMI, PSI, and 3/4 constituent subtests (i.e., Digit Span, Symbol Search, Coding) was significantly worse among the invalid group compared to the valid group ( η p 2 =.06-.16) with areas under the curve (AUCs) of.67-.76 and 24-32% sensitivity (≥88% specificity) for identifying invalid performance at cut-scores that maximized accuracy. The sample was composed of 85 patients with valid neuropsychological performance and 25 with invalid performance based on multiple independent criterion PVTs. This cross-sectional study examined data from a mixed clinical neuropsychiatric sample of 110 patients referred for outpatient evaluation. This cross-sectional study examined multiple performance validity tests (PVTs) embedded in the Wechsler Adult Intelligence Scale-IV (WAIS-IV) Working Memory (WMI) and Processing Speed (PSI) Indices for detecting invalid test performance. Validity indicators embedded within standard neuropsychological tests have received increasing attention as more efficient measures for sampling performance validity throughout an evaluation.
