Orrelations in between head cues and also a competitor's behaviour, skeptics have concluded that all these experiments endure from a `logical problem' that renders them unable to empirically distinguish representations of directly observable cues from a genuine representation of `seeing'7?0. In an attempt to overcome this difficulty, researchers have attempted to create designs that control for others' gaze. Within a landmark study, Emery and Clayton4 showed that scrub-jays recache food right after becoming watched at caching. The style controlled for occurrent gaze cues inside the test by blocking visual access to the competitor during recaching. However, it 1326631 did not handle for any memory of previous gaze cues, because the competitor was present through the initial caching episode--and so even this sophisticated design can be explained by appeal to representations of previously observed gaze cues alone7,8. Recently, Schmelz et al.11,12 showed that chimpanzees predict others' preferences inside a back-and-forth foraging game even after they never ever saw their competitors' gaze ?at the stimuli used in the test, and Ostojic et al.13,14 discovered that Eurasian jays can predict the meals preferences of their mates only if they see what they have been prefed, even when denied prior visual access to the partners' response to prefeeding within this context. Even though these lines of analysis each control for behavioural cues in sophisticated methods, they concentrate on attributions of preferences rather than sight. Hence, it still remains an open query irrespective of whether any nonhuman animal can attribute the idea `seeing' without the need of relying on behavioural cues. Like Hostal Jq Madrid 1 Tripadvisor scrub-jays15, ravens also cache food items spontaneously and they're highly sensitive towards the presence of conspecifics that might pilfer caches16. In certain, ravens reduce the likelihood of revealing cache places to competitors by (i) lowering the time to finish caches, (ii) utilizing obstacles as visual barriers for 16574785 caching outside the view of competitors, (iii) delaying caching until competitors have left and (iv) staying away from currently made caches as long as competitors are around17,18. Across all these research, even so, an additional raven was visible throughout the test, once again raising the skeptical refrain that ravens could possibly represent only gaze cues10. Suggestively, on the other hand, Stulp et al.19 and Shaw and Clayton20,21 have recently shown that jays can infer the presence of unseen conspecifics on the basis of auditory cues. These findings point the way towards the experimental design reported here, which aims to finally overcome the line-of-gaze interpretation by controlling for each (i) gaze cues in the test, by relying only on sounds to indicate the presence of a feasible competitor and (ii) memories of gaze cues previously observed within the training, by denying the subjects prior access to any competitor's gaze in contexts resembling the test. Specifically, we ask if ravens can transfer understanding from their own encounter in a novel context--using peepholes to appear into an adjacent room--to a caching situation in which they could hear but not see a conspecific in that area. The experiment was conducted in two rooms separated by a wooden wall. The wall had two functional windows that allowed visual access from 1 room into the other. Both windows could possibly be closed with covers. Moreover, every window had a peepholeNATURE COMMUNICATIONS | DOI: 10.1038/ncommsKdrilled into its cover, which could be independently opened or closed (Supplementary Fig. 1).
