> Those "spatial reasoning" questions look a lot like the IQ test I took as a kid When we took my boy for a WISC (children's IQ test) when he was ten, as part of a larger neuropsych test, he had enormous trouble with the spatial reasoning parts. The funny thing was that the test wouldn't score, as he was getting less than 5% on some of sections and more than 95% on others. This is a pattern that is apparently unlikely enough that the test assumes you aren't taking it seriously and gives up. So his IQ result was effectively "NaN". Based on that and other parts of the neuropsych, he was informally diagnosed with Non-Verbal Learning Disability (informally because NVLD isn't currently in the DSM). While the IQ test was useless for him, thankfully the diagnosis was enough to get him into a school who understood his learning style and he went from completely failing out of school in sixth grade to now just getting accepted to a highly competitive college in NYC.
