Cats seem to grasp the laws of physics

Do cats understand physics? This study suggests they do!

Thirty domestic cats were videotaped while an experimenter shook a container. In some cases this action went along with a rattling sound. In others it did not, to simulate that the vessel was empty. After the shaking phase, the container was turned over, either with an object dropping down or not.

Two experimental conditions were congruent with physical laws, where shaking was accompanied by a (no) sound and an (no) object to fall out of the container. The other two conditions were incongruent to the laws of physics. Either a rattling sound was followed by no object dropping out of the container or no sound while shaking led to a falling object.

The cats looked longer at the containers which were shaken together with a noise. This suggests that cats used a physical law to infer the existence (or absence) of objects based on whether they heard a rattle (or not). This helped them predict whether an object would appear (or not) once the container was overturned.

Researchers suggest that species’ surroundings influence their ability to find out information based on what they hear. The ecology of cats’ natural hunting style may therefore also favor the ability for inference on the basis of sounds. Takagi explains that hunting cats often need to infer the location or the distance of their prey from sounds alone because they stake out places of poor visibility. Further research is needed to find out exactly what cats see in their mind’s eye when they pick up noises, and if they can extract information such as quantity and size from what they hear.
