These tests confuse me. I consistently get in the lower 1 percentile in verbal memory. I've done the test 4 times. I never get better than the lowest percentile but my executive function test has gone as low as 2 percentile to as high as 97th percentile. Someone told me this is due to fatigue. At work though, I can't seem to multi-task suggesting I should have a very low executive function test. But sometimes it's quite high. In school, I did extremely well in memory courses (organic chemistry, life sciences) and yet my verbal memory is extremely low. I know my memory for some stuff is bad because at work I can't remember people's names, histories, drug names, etc. I'm quite bad and it shows. Maybe these tests are useless?
I'm wondering if these tests are normed off age... That is, your particular percentile is determined by your particular age group. This would be important because older testers would be expected to have lower verbal memory as memory declines with age and if they weren't stratified by age, then someone older would have unusually low scores.
This part of the intro suggests that they do, though: "You are asked your age only to allow scoring of the test by the computer."
However, it seems there's a noticeable difference in verbal memory scores, so far, between younger and older testers. So, they might not.
Also, this test only tests relatively immediate verbal memory and "sort of delayed" memory. Real "delayed memory"(I.e., more than 2 hours, the kind tested by school tests) is something different and Wechsler uses a delay of at least an hour for his tests, so the delayed memory part of this test might not be indicative of your delayed memory in "real life". Also, the kind of memory used during school tests is not only verbal memory, but also semantic memory and visual memory which aren't specifically tested here.
