“…Moreover, we found that dogs’ looking time was not modulated by ostensive cues. In contrast to infants tested in a previous study (Yoon et al, 2008; but see Silverstein et al, 2019), dogs noticed kind changes in both ostensive and nonostensive contexts and failed to notice location changes in either context. Thus, dogs’ ability to encode kind-relevant information may not be modulated by ostensive cues in the same way that infants’ ability is.…”

“…This pattern of results was true regardless of whether dogs learned about objects ostensively or nonostensively. These findings contrast with those of human infants who selectively noticed kind-relevant changes in ostensive contexts, suggesting that these infants expected ostensively communicated information to generalize (Yoon et al, 2008; but see Silverstein et al, 2019). The findings of the current looking time studies add to existing behavioral work with dogs (Topál et al, 2009), suggesting that dogs do not expect ostensive communication to generalize in the same way as human infants.…”

“…Most notably, the researchers controlled for the amount of time the ostensive and nonostensive cues were presented, which was not done in the original Yoon et al (2008) study in which ostensive cues were presented for a longer amount of time. Silverstein et al (2019) failed to find any evidence that infants were more sensitive to kind changes in the ostensive condition and location changes in the nonostensive condition. Instead, they found that infants were more likely to notice kind changes across both ostensive and nonostensive contexts.…”

“…However, these results should be interpreted with some caution, given that a group of researchers recently failed to replicate the original study by Yoon et al (2008;Silverstein et al, 2019). In two experiments, Silverstein et al (2019) used a method similar to that of Yoon et al (2008) study with a few exceptions. Most notably, the researchers controlled for the amount of time the ostensive and nonostensive cues were presented, which was not done in the original Yoon et al (2008) study in which ostensive cues were presented for a longer amount of time.…”

Our human capacity to efficiently learn from other individuals is unparalleled in any nonhuman species. Some scholars argue that our propensity to learn socially is supported by an early-emerging expectation that communicative cues will convey generic information ). In the current 2 studies, we examine whether this expectation about generic information is unique to humans by testing a species that readily attends to human cues-dogs. Specifically, we adapted a violation of expectation paradigm previously used with human infants to examine whether communicative cues lead dogs to selectively encode generic, kind-relevant information about objects (e.g., shape). Prior work has demonstrated that human infants are more likely to notice unexpected changes in kind-relevant information in communicative contexts (i.e., when an agent points to the object; Yoon et al., 2008). In contrast, across 2 studies (N = 136), dogs were no more likely to notice kind-relevant changes in communicative contexts than noncommunicative contexts. These findings suggest that although dogs attend to human communicative cues, such cues do not shape the way that dogs encode objects. More broadly, this finding lends support to the claim that our early-emerging generic expectation crucially supports our human capacity to efficiently learn from one another.
