Pigeons process actor-action configurations more readily than bystander-action configurations.

Area of Science:

• Comparative Cognition
• Animal Behavior
• Action Recognition

Background:

• Behavior necessitates an actor, and understanding how animals process actor-behavior relationships is crucial.
• Previous research has explored observational learning and social cognition in animals, but the role of actor identity in action discrimination requires further investigation.

Purpose of the Study:

• To investigate whether pigeons prioritize information about a digital actor performing a behavior.
• To examine if pigeons can conditionally discriminate actions based on the identity of the digital actor versus a bystander.

Main Methods:

• Two experiments employed complex conditional action discrimination tasks using video displays of digital models.
• Pigeons were presented with two video displays, each featuring a digital model (actor or bystander) engaged in distinct behaviors (Indian dance or martial arts).
• Discrimination accuracy was assessed based on whether pigeons could link actions to the actor's identity.

Main Results:

• Pigeons trained to associate actions with the actor-model (actor-conditional) successfully learned the discrimination.
• Pigeons trained to associate actions with the bystander-model (bystander-conditional) failed to learn the discrimination.
• Experiment 2 ruled out spatial integration limitations as the cause for the bystander-conditional group's failure.

Conclusions:

• Pigeons privilege information linking behavior to a specific actor, suggesting a fundamental configural representation of actor identity and action.
• These findings advance our understanding of the evolution of action recognition and social behavior in animals.
• The results provide insights into the mechanisms of observational learning in non-human species.
