I am not sure about the "comprehension" subtest but I remember one of the pictures one being bad. I think the person testing looks at a bunch of pics together (maybe three, not sure) and has to say what they all have in common or something. Anyway, my son came out and said there was a picture of what appeared to be a keyboard but it had no monitor and, like a printer, paper was coming out of it. It was obviously a typewriter something a 6 year old would have never seen (at least not where we are). Also he described an iron - he recognized as a monopoly piece but had no idea it was an "iron" that it gets hot and one irons clothes with it. When I was a kid my mom ironed every Thursday while watching her soaps. Yeah. I have no idea where our iron is and we have never had an ironing board. I don't think people really do that anymore... I know of no one who irons regularly. I am sure many many many kids in this day and age have not seen I real iron in use. And that was just the two I remember. I remember there more!
