I think that my IQ test result from V 2016 indicate some definite form of NVLD, but it is quite atypical. WCST (Wisconsin Card Sorting Test) and a test associated with drawing 2D figures after looking at them at the paper from memory suggest:
- WCST - very poor executive functioning, results not better than 15th percentile, sometimes lower than 5th, one subscale ("learning of learning") was even below 1st percentile,
- on the test about drawing figures I made 4 errors when the norm is 0 or 1 error - it suggests poor visual memory which is consistent with the suspicion of NVLD.
Arguments against NVLD (based on Wechsler IQ test):
1. Arithmetic in gifted range (18, corresponding to IQ 141, about the 99,68 precentile).
2. Vocabulary more than 3 "large" points higher than Arithmetic (14, corresponding to IQ about 117 - 123).
3. Good result in Block Design (14, the highest in PIQ part).
4. Good (but not as good as result in BD) result in Coding (13).
5. Similarities lower than Block Design (13 vs 14).
Arguments for NVLD (based mostly on Weschler IQ test):
1. VIQ 22 points higher than PIQ (126 vs 104).
2. Perceptual Organization Index (POI) 25 points lower than Verbal Comprehension Index (100 vs 125).
3. Highest from: Information, Similarities, Vocabulary (Information, 17) 8 "large" points higher than lowest from: Block Design, Coding, Object Assembly (Object Assembly, 9) - it corresponds to about 40 IQ points.
4. Relatively low Digit Span (especially backwards!) - 11, the lowest among VIQ scores after Comprehension and Similarities (13).
5. Quite poor performance in Picture Arrangement (8, corresponding to IQ 89 (29th percentile)).
6. Quite poor performance in Picture Completion (only 9).
7. Difference between the highest VIQ subscale (Arithmetic) and the lowest PIQ scale (Picture Arrangement) is 10 "large" points, which is quite big difference (lower means IQ 89 and 23th percentile (only less than 1 from 4 persons have lower), higher means IQ 141 and about 99,68th percentile (only about 1 on 319 have higher), there are 52 points of difference (almost 3,5 standard deviations) and the quotient of 319 and 1/4 is very large (1276)).
8.The quotient of the frequencies of result about 99,68th percentile (319) - Arithmetic in Wechsler test and of result below 1st percentile (less than 0,01) - learning of learning in WCST is 31900 - it is very large number.
