So there's no equivalent to block design on the RIAS, nor to what's missing on the WISC-IV. The only point of overlap is matrix reasoning to OIO, and even then it's not exactly the same, as one is more inductive and the other is more deductive reasoning. Taking ZS's observation into account, it may be that having the pattern to start from narrows down the pool of responses, making it easier for him to read the test designer on matrix reasoning. (A skill, btw, which my mother overtly instructed us to apply to the taking of standardized tests.)
