dc.description.abstractSocial learning is of universal importance to animal life and communication is likely to foster it. How do animals recognise when others produce actions that lead to relevant new information? To address this, we exposed four chimpanzees to an arbitrary learning task, a two-choice visual discrimination paradigm presented on a touch screen that led to food rewards. In each trial, images were paired with one of four acoustic treatments: 1) relevant or 2) irrelevant chimpanzee calls (‘rough grunts’ to food; ‘pant grunts’ to a dominant conspecific), 3) a mechanical noise (hammer knocking sounds) 4) silence. As we were interested in the effect of food calls on learning speed as compared to control stimuli, each chimpanzee was tested with the food call treatment, and one of the three control stimuli (either the pant grunt, mechanical noise or silence condition). We found that learning was significantly enhanced in the contextually correct ‘rough grunt’ condition, suggesting that food calls may play a role in the cultural transmission of food preferences, by priming individuals about a learning opportunity. We discuss these findings and propose that, at least in chimpanzees, the enhancing effect of these vocalisations may be related to the way they affect receivers’ motivational/emotional and attentional systems.
