Mumofthree, sorry to hear your DD had that experience. I hope it has not stood in the way for her. I wonder if some testers might see a 4 year old having an emotionally based lack of completion as a "spoiled" subtest and therefore administer a supplemental subtest to be used instead in score calculation. That would seem fair to me were I a test author as I don't think at that age they are meaning to test simple compliancy. Or maybe they are.

Ashley -- Just for future reference, the wisc iv guide I am reading mentions the matrix reasoning subtest specifically as more difficult to interpret if a child has color blindness. ie it sounds like there may be some aspects that depend on color recognition.
