N2 - Interactions and communication between individuals occur in a complex social environment in which senders and receivers are able to adjust their behaviour according to the context. Watching fights between others acts on a bystander’s motivation to engage in a fight and may make it behave more aggressively during subsequent disputes. This phenomenon is known as aggressive priming. The aim of our study was to investigate if this priming response follows a step function, i.e. appears only above a threshold level of aggression witnessed by a bystander. We found that bystanders behaved more aggressively in subsequent interactions when pre-exposed to an aggressive conspecific that was engaged in a fight whatever the level of aggression this fight reached. However, bystanders’ behaviour after pre-exposure was not correlated to the previously witnessed level of aggressiveness. These results suggest that individuals alter their behaviour in an aggressive social environment and indicate that priming effect follows a step function where aggression is triggered by an aggressive context. We discuss our results and the effect of pre-exposure on agonistic interactions in a communication network perspective.
