通过呈现印记刺激来控制行为。

Science. 1960 Nov 11;132(3437):1395-6. doi: 10.1126/science.132.3437.1395.

When presentation of an imprinted stimulus is contingent upon an arbitrarily chosen response, the rate of emission of this response increases. This control of responding requires a moving imprinted stimulus and does not require a following response by the duck.

当印记刺激的呈现取决于一个任意选择的反应时，这个反应的发出速率会增加。这种对反应的控制需要一个移动的印记刺激，并且不需要鸭子随后做出反应。
