Auditory⁻Visual Matching of Conspecifics and Non-Conspecifics by Dogs and Human Infants.

ABSTRACT: We tested whether dogs and 14⁻16-month-old infants are able to integrate intersensory information when presented with conspecific and heterospecific faces and vocalisations. The looking behaviour of dogs and infants was recorded with a non-invasive eye-tracking technique while they were concurrently presented with a dog and a female human portrait accompanied with acoustic stimuli of female human speech and a dog's bark. Dogs showed evidence of both con- and heterospecific intermodal matching, while infants' looking preferences indicated effective auditory⁻visual matching only when presented with the audio and visual stimuli of the non-conspecifics. The results of the present study provided further evidence that domestic dogs and human infants have similar socio-cognitive skills and highli
