Abstract

Ten-month-old infants search for a hidden object persistently at its initial hiding place even after observing it being hidden at another location. Recent evidence suggests that communicative cues from the experimenter contribute to the emergence of this perseverative search error. Here we replicate these results with dogs, who also commit more search errors in ostensive-communicative (in 75% of the total trials) than in non-communicative (39%) or non-social (17%) hiding contexts. However, comparative investigations suggest that communicative signals serve different functions for dogs and infants, while human-reared wolves do not show dog-like context-dependent differences of search errors. We propose that shared sensitivity to human communicative signals stems from convergent social evolution of the Homo and the Canis genera.
