It is now clear that this is not so. Babies will learn to behave in ways that produce re suits in the world with no reward except the successful outcome. Papousek began his studies by using milk in normal way to "reward' the babies and so teach them to carry out some simple movements, such as turning the head to one side or the other. Then he noticed that a baby who had enough to drink would refuse the milk but would still go on making the learned response with clear signs of pleasure. So he began to study the children's responses in situations where no milk was provided. He quickly found that children as young as four months would learn to turn their heads to right or left if the movement "switched on' a display of lights and indeed that they were capable of learning quite complex turns to bring about this result, for instance, two left or two right, or even to make as many as three turns to one side. Papousek's light display was placed directly in front of the babies and he made the interesting observation that sometimes they would not turn back to watch the lights closely al though they would "smile and bubble when the display came on. Papousek concluded that it was not primarily the sight of the lights which pleased them, it was the success they were achieving in solving the problem, in mastering the skill, and that there exists a fundamental human urge to make sense of the world and bring it under intentional control. According to the author, babies learn to do things which ______. A．will satisfy their curiosity B．will meet their physical needs C．are directly related to pleasure D．will bring them a feeling of success

So I was【66】by what's being called "the largest meta-analysis ever conducted on the association between parenting styles and delinquency (犯罪，尤指青少年). " The meta. analysis, in the Journal of Abnormal Child Psychology, looked at 161 published and unpublished studies【67】the question, and found that how well parents【68】their children, whether they expressed rejection or hostility, and a number of other【69】indeed had an effect. What's particularly interesting is the【70】of the effect. An association can be statistically significant without being【71】significant; that is, there can be true cause-and-effect, but a tiny effect. Not so in this case.【72】kids for good behavior. had an effect size of 11%, for instance; not huge, but not tiny (it means that 11% of the difference between kids' levels of delinquency is due to whether their parents rewarded them for good behavior, something that reduces delinquency). Being authoritative also【73】delinquency, again with an effect size of 11%,【74】being authoritarian (独裁) increased delinquency, with an effect size of 12%. Put the two together and being authoritarian as opposed to authoritative【75】for a swing of 23%. Physical【76】and verbal aggression also were associated with more delinquency. The "parents don't matter" school might【77】that little delinquents-to-be bring out the worst in parents, who turn authoritarian. It is the kids'【78】tendencies that cause later delinquency, according to this argument, not how parents【79】. The【80】with this claim is the many studies showing that whether you are an authoritarian or an authoritative parent "is most often determined before your first kid is even born, and is highly【81】upon your own experience of discipline.., and your general political/personality orientation," as clinical psychologist Nestor Lopez-Duran wrote.
