ABSTRACTCommunication during play fighting can be crucial in facilitating and sustaining contact. As juvenile rats play mostly in the dark, visual signals are unlikely to fulfill this function. However, during play, rats have a variety of ultrasonic calls that are emitted and there is growing evidence that some of these calls may provide a means of communication. Particular calls are associated with particular actions and in the present paper we show that specific calls by one rat changes the probability of the actions taken by another. We have found that some calls appear to act as a means of sustaining the animals’ playful mood and so facilitate the occurrence of play, some calls ensure that the interaction remains playful and so avoid escalation to aggression, and some appear to promote reciprocal exchanges and so ensure that playful contact continues. |
