　　For some time past it has been widely accepted that babies and other creatures learn to do things because certain acts lead to "rewards"; and there is no reason to doubt that this is true. But it used also to be widely believed that effective rewards, at least in the early stages, had to be directly related to such basic physiological(生理的) "drives" as thirst or hunger. In other words, a baby would learn if he got food or drink or some sort of physical comfort, not otherwise.
% `, N4 F- K7 n- x0 T　　It is now clear that this is not so. Babies will learn to behave in ways that produce results with no reward except the successful outcome.
- v1 T" Y6 ^+ t7 Y0 b* E, n　　Papousek began his studies by using milk in the 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 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 although 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.

' g# `* s" Z2 ]1 p6 R0 k7 U% N- G& O　　There are various ways in which individual economic units can interact with one another. These basic ways may be described as the market system, the administered system, and the traditional system.
　　In a market system individual economic units are free to interact among each other in the marketplace. It is possible to buy goods from other economic units or sell goods to them. In a market, transactions may take place through barter or money exchange. In a barter economy, real goods such as automobiles, shoes, and rice are traded against each other. Obviously, finding somebody who wants to trade my old car in exchange for a sail-boat may not always be an easy task. Hence, the introduction of money as a medium of exchange eases transactions considerably. In the modern market economy ? goods and services are bought or sold for money.
　　An alternative to the market system is administrative control by some agency over all transactions. This agency will issue commands as to how much of each goods and service should be produced, and consumed by each economic unit. Central planning may be one way of running such an economy. The central plan, drawn up by the government, shows the amounts of each goods produced by the various firms and shared among different households for consumption. This is an example of complete planning of production, consumption, and exchange for the whole economy.
　　In a traditional society, production and consumption patterns are governed by tradition; every person's place within the economic system is fixed by fatherhood or motherhood, religion, and custom. Transactions take place on the basis of tradition, too.
