We tested domestic dogs (N = 16) in a Guesser–Knower task in which they chose between possible locations for hidden food indicated by human informants. In four experiments, the perceptual access of the Guesser and Knower to the hidden food baiting was manipulated. When informants had differing perceptual access to the baiting, dogs preferred the location indicated by the Knower from the start of testing (Experiment 1), even when baiting was done by a third experimenter (Experiments 2–3… 
Dogs demonstrate perspective taking based on geometrical gaze following in a Guesser–Knower task
TLDR
With 16 dogs, this work replicated the main results of Maginnity and Grace, and extended this finding with a further, critical control for behaviour-reading: two informants showed identical looking behaviour, but due to their different position in the room, only one had the opportunity to see where the food was hidden by a third person.
Metacognition in canids: A comparison of dogs (Canis familiaris) and dingoes (Canis dingo).
TLDR
Evidence is found that both dogs and dingoes sought out information and were more likely do so when they did not already know where the treat was hidden, the first evidence of similar behavior in a nondomesticated canid.
What’s the point? Domestic dogs’ sensitivity to the accuracy of human informants
TLDR
Dogs excel at understanding human social-communicative gestures like points and can distinguish between human informants who vary in characteristics such as knowledge or familiarity, which suggests that like children, dogs may be able to use informants’ past accuracy when choosing between information sources.
Dogs do not demonstrate a human-like bias to defer to communicative cues
TLDR
Findings provide clear evidence that dogs do not demonstrate a human-like bias to defer to communicative cues, and dogs may be more likely to critically evaluate information presented via Communicative cues than either physical or non-communicative cues.
Do You Know What I See ? Visual Perspective Taking in Nonhuman Animals
TLDR
This paper reviews some of the prominent experimental paradigms and research findings on visual perspective taking in various nonhuman species, such as the begging task, the guesser-knower task, and competitive paradigm, and suggests that future research should aim to overcome the challenges of this area of study.
Dogs follow human misleading suggestions more often when the informant has a false belief
TLDR
Evidence that pet dogs distinguish between TB and FB scenarios is provided, suggesting that the mechanisms underlying sensitivity to others' beliefs have not evolved uniquely in the primate lineage.
Horses with sustained attention follow the pointing of a human who knows where food is hidden
TLDR
Horses that sustained high attention levels could evaluate the credibility of the information and followed the pointing of an informant who knew where food was hidden, suggesting that horses are highly sensitive to the attentional state and pointing gestures of humans, and that they perceive pointing as a communicative cue.
Belief Contagion : Susceptibility to Others ’ Beliefs in Canis familiaris By
TLDR
Analysis of theory of mind in dogs using a searching time paradigm as part of a novel false belief task suggests automatic belief representation and contagion may be an aspect of core knowledge unique to humans.
Intuitive probabilistic inference in capuchin monkeys
TLDR
The first investigation of probabilistic inference in a monkey species (capuchins; Sapajus spp.) revealed that at least some capuchins were able to make Probabilistic inferences via reasoning about proportions as opposed to simpler quantity heuristics.

Inferences about guessing and knowing by chimpanzees (Pan troglodytes).
TLDR
The visual perspective-taking ability of 4 chimpanzees (Pan troglodytes) was investigated and results are consistent with the hypothesis that chimpanzees are capable of modeling the visual perspectives of others.
Use of experimenter-given cues in dogs
TLDR
It is suggested that the phenomenon of dogs responding to cues given by humans is better analysed as a case of interspecific communication than in terms of discrimination learning.
Understanding of the relationship between seeing and knowing by tufted capuchin monkeys (Cebus apella)
TLDR
It is suggested that capuchin monkeys can learn to recognize the relationship between seeing and knowing.
Do rhesus monkeys (Macaca mulatta) attribute knowledge and ignorance to others
TLDR
None of the macaques provided any evidence that they realized the different states of knowledge possessed by the guesser and knower, consistent with the hypothesis that rhesus macaques are incapable of making inferences about the mental states of others.
Are readers of our face readers of our minds? Dogs (Canis familiaris) show situation-dependent recognition of human’s attention
TLDR
It is concluded that dogs are able to rely on the same set of human facial cues for detection of attention, which form the behavioral basis of understanding attention in humans.
A nonverbal test of knowledge attribution: a comparative study on dogs and children
TLDR
Even the subtle distinction made by the children can be interpreted without a casual understanding of knowledge-formation in others in a playful, nonverbal task in which a human Helper’s knowledge state regarding the whereabouts of a hidden toy and a stick was systematically manipulated.
Cues to food location that domestic dogs (Canis familiaris) of different ages do and do not use
TLDR
The results suggest the possibility that domestic dogs have evolved an adaptive specialization for using human-produced directional cues in a goal-directed (especially foraging) context.
Behaviour of domestic pigs in a visual perspective taking task
Animals with visual perspective taking abilities should differ in their responses to individuals that do and individuals that do not have visual access to some critical event. We investigated whether
A comparative study of the use of visual communicative signals in interactions between dogs (Canis familiaris) and humans and cats (Felis catus) and humans.
TLDR
The results suggest that individual familiarization with pointing gestures ensures high-level performance in the presence of such gestures; however, species-specific differences could cause differences in signaling toward the human.
Comprehension of human communicative signs in pet dogs (Canis familiaris).
TLDR
The hypothesis is that dogs spend more time in close contact with humans than apes do, and as a result dogs are probably more experienced in the recognition of human gestures.
