ABAS and BASC also provide those functions but Vineland is for adults also. Wechsler IQ testing wouldn’t be valid due to his eye issues. He couldn’t do the Processing Speed Subscale items (symbol search and coding) in a manner which has been validated so he’d be artificially lower on his FSIQ score. Plus his linguistic issues could cause problems on digit span, so lower WM.
the Leiter would give a better estimate as it’s a nonverbal test of intelligence.
my guess is that Russell is average IQ tbh. Not actually as intelligent as Lucas Werner but still more functional due to not having bipolar or schizophrenia. Both, however, struggle with Dunning Kruger due to their narcissism so they end up having stunning displays of poor critical thinking. It’s not, for example, that Russell doesn’t understand how to read certain legal cases. The issue is that he thinks he is right from the get go so he reads the information and simply ignores parts that conflict by deciding those parts are inconsequential. Lucas does this alllll the time with research articles which often say the opposite.
both Russell and Lucas seem to have higher than average verbaL fluency IQs (lucas seems higher), but I’m guessing Russell and Lucas probably both struggle with perceptual reasoning. Look at how they wrote their respective love notes. Their spatial awareness and pattern finding seems low. Russell’s processing speed would be terrible but so is lucas’ due to meds. I think Working memory tasks are won by lucas again. His ability to recall (incorrect) but consistent numbers is pretty interesting. But WM declines with age and is impacted by psychotropics so lucas might be blunted there. As noted, Russell would be unintelligible for DS tasks and maybe even arithmetic.
I think given the higher Verbal performance, Russell would be able to score average or a bit above average on IQ testing (but not even a full SD above).
