Okay, so if I just show you the percentage errors in a large developmental study we did, this is in a study ranging from age seven to adulthood, and what you're going to see is the percentage errors in the adult group in both conditions, so the gray is the director condition, and you see that our intelligent adults are making errors about 50 percent of the time, whereas they make far fewer errors
这个就是在我们较大规模的研究中 得出的犯错比率， 这是从七岁到成年的一个研究， 你们接下来会看到的就是成人组 在两种条件下的错误比率， 灰色的就是有引导员的情况， 你会发现我们聪明的成年人的错误率约是50% 但是他们在没有引导员在场的情况下。
