text: While a child is learning, for instance, a math program site, they could be trying to get in it but there are ads that pop up ,in paragrah 6 it states that "if you smile when a Web ad apperars on your screen, a similar ad might follow. But if you frown, the next ad will be different." If a child looks away from the computer at his/her friend to wait for he ad to be over that he/she doesn't want, and smiles while glancing down to the screen to see if the ad is over, the computer could take this as a happy signal for the ad. So then it will play another one that is similar to the ad that the child did not want.
