A successful procedure for studying imitative behavior in non-humans is the bidirectional control procedure in which observers are exposed to a demonstrator that responds by moving a manipulandum in one of two different directions (e.g., left vs. right). Imitative learning is demonstrated when observers make the response in the direction that they observed it being made. This procedure controls for socially mediated effects (the mere presence of a demonstrator), stimulus enhancement (attention drawn to a manipulandum by its movement), and if an appropriate control is included, emulation (learning how the environment works). Recent research with dogs has found that dogs may not demonstrate imitative learning when the demonstrator is human. In the present research, we found that when odors were controlled for, dogs imitated the direction of a screen-push demonstrated by another dog more than in a control condition in which they observed the screen move independently while another dog was present. Furthermore, we found that dogs would match the direction of screen-push demonstrated by a human and they were equally likely to match the direction in which the screen moved independently while a human was present.
一种用于研究非人类模仿行为的成功方法是双向控制程序,在该程序中,观察者会接触到一个示范者,示范者通过在两个不同方向之一(例如,向左或向右)移动一个操作柄来做出反应。当观察者朝着他们观察到示范者做出反应的方向做出反应时,就证明了模仿学习。该程序控制了社会介导效应(示范者的单纯存在)、刺激增强(操作柄的移动引起对它的注意),并且如果包含适当的对照,则控制了模仿(学习环境如何运作)。最近对狗的研究发现,当示范者是人类时,狗可能不会表现出模仿学习。在本研究中,我们发现当控制气味时,狗模仿另一只狗示范的推屏幕方向的次数比在对照条件下更多,在对照条件下,它们观察到屏幕在另一只狗在场时独立移动。此外,我们发现狗会匹配人类示范的推屏幕方向,并且它们同样有可能匹配在人类在场时屏幕独立移动的方向。
