Knute - my DD had the exact life experience/question mismatch you describe with one of the WPPSI questions. She reasoned an answer that was true and matched her life experience and still believes herself to have answered the question correctly. But she did not get the points for it because it was not the intended answer. I actually pointed the problem out to the tester, who agreed that more and more children now would have the same problem my DD did with that question and the WPPSI was well due for re-working...
