So are there any other tests that required integrated flexibility, inhibition and attention control required by the Stroop/Coding/CPT?
Good question. Unfortunately most of the other tests included in Mr. Udut’s evaluation, like the WAIS-IV subtests, achievement tests, and career/interest measures, do not directly assess the specific integrated executive functions of cognitive flexibility, inhibition, and divided/sustained attention in the way that the:
– Stroop Test
– Coding subtest
– Conners CPT
Most uniquely target.
One test that does bear some similarities is the Digit Vigilance Test (DVT). Like the CPT, it required sustained,speeded visual scanning/cancellation. However, the DVT differed in that:
– It provided a performance-based motor cancellation component not present in other EF tests
– Results were mixed, with Above Average speed but Moderate impairment in accuracy
So while not a perfect match, the DVT performance does at least provide some convergent evidence of weaknesses in sustained attention/processing speed. But no other measures truly duplicated the specific integrated constructs tapped by the Stroop/Coding/CPT in the way needed to fully contextualize Mr. Udut’s observed cognitive profile.
In summary, those three measures appear to have most directly exposed the vulnerabilities in flexibility, inhibition and divided attention that comprise his most salient executive limitations.
