High-pitch sounds small for domestic dogs: abstract crossmodal correspondences between auditory pitch and visual size.

ABSTRACT: Humans possess intuitive associations linking certain non-redundant features of stimuli-e.g. high-pitched sounds with small object size (or similarly, low-pitched sounds with large object size). This phenomenon, known as crossmodal correspondence, has been identified in humans across multiple different senses. There is some evidence that non-human animals also form crossmodal correspondences, but the known examples are mostly limited to the associations between the pitch of vocalizations and the size of callers. To investigate whether domestic dogs, like humans, show abstract pitch-size association, we first trained dogs to approach and touch an object after hearing a sound emanating from it. Subsequently, we repeated the task but presented dogs with two objects differ
