I posted earlier regarding my son's scores and low processing speed, but I have another question about how processing speed contributes to the FSIQ. His scores were as follows (percentiles):
Information: 91
Vocabulary: 99
Word reasoning: 95
Block design: 84
Matrix reasoning: 99
Picture concepts: 98
Coding: 16 (eek)
Composites:
Verbal: 99
Performance: 99
FSIQ: 98
Is the coding score not heavily weighted, or not included in the FSIQ here? I guess I was wondering how the FSIQ still ended up at the 98th percentile despite the really low coding score. I do know the WPPSI III has been superceded and so the overall scores may be inflated.
I don't know specifically how the scores are calculated, but on the WISC my ds scores a high FSIQ in spite of a large discrepancy in processing speed. The key is how rare the combination of the other high scores is (I think!).
