Researchers have found that dogs adapt their communicative strategies to their environment and that owner behavior influences communicative effort and success.
Given the remarkable sensitivity of dogs to human vocalizations, gestures and gazes, researchers have suggested that 30.000 years of domestication and co-evolution with humans may have caused dogs to develop similar principles of communication — a theory known as the domestication hypothesis.
On this basis, researchers designed an experiment that would examine the factors influencing the form, effort and success of dog-human interactions in a hidden-object task. Using 30 dog-owner pairs, researchers focused on a communicative behavior called showing, in which dogs gather the attention of a communicative partner and direct it to an external source.
While the owner waited in another room, an experimenter in view of a participating dog hid the dogs` favorite toy in one of four boxes. When the owner entered the room, the dog had to show its owner where the toy had been hidden. If the owner successfully located the toy, the pair were allowed to play as a reward. Participants were tested in two conditions: a close setup which required more precise showing and a distant setup which allowed for showing in a general direction.
The findings indicate that a crucial factor influencing the effort and accuracy of dogs’ showing is the behavior of the dog’s owner. Owners who encouraged their dog to show where the toy was hidden increased their dog’s showing effort but generally decreased their showing accuracy. Bottom line: the current study indicates for the first time that owners can influence their dog’s showing accuracy and success.
