Data for "Pigeons (Columba livia) process actor-action configurations more readily than bystander-action configurations"

Behavior require an actor. Two experiments using complex conditional action discriminations examined whether pigeons privilege information related to the performing digital actors. Each video display contained two digital models, an actor engaged in one of two behaviors (Indian dance or martial arts) and 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, while 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 co-localization of the relevant model identity and the action was critical due to a fundamental configural 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.
