[QUOTE="Marguerite, post: 150006, member: 1991"] Thanks for the distinction - I didn't see the reference to how recent it was. My concern was primarily to do with IQ testing and the perhaps too great a reliance placed on the results, as well as the problems from having IQ tests done too close together. We've been told there should be at least two years between tests. But again, that's IQ tests. If you examine the sub-scores and want more information than they can give you, you can always have supplementary testing done within that time-frame, to go into more detail. Sub-sub tests, if you will. We did that with difficult child 1 when he scored so low in one sub-test that we wanted to know why. Another psychologist looked purely at that area of concern and said he had another four or five tests he could do, each examining a portion of that area. It's like having a blood test where a doctor is looking at a smear of your blood on a microscope slide. A half-hour IQ test is like holding the microscope slide up to the light and trying to see with the naked eye, enough detail to make any kind of diagnosis. Perhaps, at a stretch, you could say, "the slide looks a bit pale, you might be anaemic," but frankly, you just can't see enough to be sure. Or for a more appropriate test, one which goes for a number of hours, it's like the doctor putting the slide under a microscope at 300x and then using a counting grid to say, "You have W number of red blood cells and T number of white blood cells, therefore you are not anaemic, but the white count is slightly elevated which indicates a possible infection." Or for the really specialised tests which only look at one particular area - the doctor hands the slide over to a haematologist, who examines it more closely and says, "of the white cells here, your monocytes (one kind of white cell) are showing abnormalities which are indicative of a particular form of leukemia." Or the specialist could look in even more detail at even higher magnification (under an electron microscope, for example) and say, "when we really look into the fine detail of your monocytes, I can discern some defects in cell membrane function which could account for the abnormalities we've noticed at lower magnification." Of course,while he's looking at a single monocyte under the electron microscope, he's not looking at anything else. The capacity for detailed examination is there in everything. But you should only look if there is a need. To look with that degree of detail, at everything, takes too long. You should only zoom in on the areas of concern. In difficult child 3's case, the psychologist discovered a problem for difficult child 3 in transferring information from one point to another. While part of that problem relates to difficult child 3's poor short-term memory, another part COULD be fixed - difficult child 3's vision. With reading glasses plus special prisms to make his eyes work a bit harder, difficult child 3's information transfer rate improved. As smallworld mentioned, there are other test procedures which also should give you valuable information. Her psychological state is also important, because the smartest child in the world won't do well if she is deeply depressed or lacks motivation. Marg [/QUOTE]
