My daughter was tested for ADHD, visual perception, auditory perception and memory, in addition to another administration of IQ and achievement, the WISC IV and WIAT.
Some examples;
Her auditory sentence memory percentile rank was 79, while her word memory percentile rank was 45. Her word discrimination landed at the 1st percentile! Her compensation strategy for information presented via auditory means is to figure it our based on the context of the discussion/topic. _
This deficit matched her very low (unfamiliar) word and pseudo-word decoding skills which we have been warned will affect her reading comprehension. Her reading comprehension abilities have been greatly supported, to this point, by her very strong vocabulary skills. However, we are just recently seeing her reading comprehension percentile ranking decline as had been predicted. Although, this has occurred later than expected.
