Humans communicate with each other through language, which enables us talk about things beyond time and space. Do non-human animals learn to associate human speech with specific objects in everyday life?

We examined whether cats matched familiar cats’ names and faces (Experiment 1) and human family members’ names and faces (Experiment 2). Cats were presented with a photo of the familiar cat’s face on a laptop monitor after hearing the same cat’s name or another cat’s name called by the subject cat’s owner (Experiment 1) or an experimenter (Experiment 2). Half of the trials were in a congruent condition where the name and face matched, and half were in an incongruent (mismatch) condition.

Results: One cat completed only the first trial before escaping from the room and climbing out of reach…1 showed that household cats paid attention to the monitor for longer in the incongruent condition, suggesting an expectancy violation effect; however, café cats did not. In 2, cats living in larger human families were found to look at the monitor for increasingly longer durations in the incongruent condition. Furthermore, this tendency was stronger among cats that had lived with their human family for a longer time, although we could not rule out an effect of age.

This study provides evidence that cats link a companion’s name and corresponding face without explicit training.
