Papousek began his studies by using milk in the normal way to reward"the babies and so taught 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 childrens 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 31.
