Behavior requires an actor. Two experiments using complex conditional action discriminations examined whether pigeons privilege information related to the digital actor who is engaged in behavior. In Experiment 1, each of two video displays contained a digital model, one an actor engaged in one of two behaviors (Indian dance or martial arts) and one a neutrally posed bystander. To correctly classify the display, the pigeons needed to conditionally process the action in conjunction with distinctive physical features of the actor or the bystander. Four actor-conditional pigeons learned to correctly discriminate the actions based on the identity of the actors, whereas four bystander-conditional birds failed to learn. Experiment 2 established that this failure was not due to the latter group's inability to spatially integrate information across the distance between the two models. Potentially, the colocalization of the relevant model identity and the action was critical due to a fundamental configural or integral representation of these properties. These findings contribute to our understanding of the evolution of action recognition, the recognition of social behavior, and forms of observational learning by animals.

鸽子比旁观者行为配置更容易处理参与者的行为配置。

行为需要演员。使用复杂的条件动作判别进行的两个实验检查了鸽子是否与从事行为的数字演员有关的特权信息。在实验1中，两个视频显示中的每一个都包含一个数字模型，一个是从事两种行为（印度舞蹈或武术）之一的演员，一个是中立的旁观者。为了正确地对显示进行分类，鸽子需要结合演员或旁观者的独特身体特征，有条件地对动作进行处理。四只以角色为条件的鸽子学会了根据角色的身份正确地区分行为，而四只以旁观者为条件的鸽子则没有学习。实验2确认此失败不是由于后一组 无法跨两个模型之间的距离在空间上整合信息。由于这些属性的基本配置或整体表示，潜在的相关模型标识和操作的共本地化至关重要。这些发现有助于我们理解动作识别的演变，对社会行为的认识以及动物的观察学习形式。
