In the present experiments, the 2-action method was used to determine whether pigeons could learn to imitate a conditional discrimination. Demonstrator pigeons (Columba livia) stepped on a treadle in the presence of 1 light and pecked at the treadle in the presence of another light. Demonstration did not seem to affect acquisition of the conditional discrimination (Experiment 1) but did facilitate its reversal of the conditional discrimination (Experiments 2 and 3). The results suggest that pigeons are not only able to learn a specific behavior by observing another pigeon, but they can also learn under which circumstances to perform that behavior. The results have implications for proposed mechanisms of imitation in animals.
在当前的实验中,采用双动作法来确定鸽子是否能够学会模仿条件辨别。示范鸽(家鸽)在一种光出现时踩踏板,在另一种光出现时啄踏板。示范似乎并不影响条件辨别学习(实验1),但确实促进了条件辨别逆转(实验2和3)。结果表明,鸽子不仅能够通过观察另一只鸽子来学习特定行为,还能学会在何种情况下执行该行为。这些结果对动物模仿的潜在机制具有启示意义。
