Title Bird song learning in an eavesdropping context Type Journal Article
Year 2007 Publication Animal Behaviour. Abbreviated Journal Anim. Behav.
Volume 73 Issue 6 Pages 929-935
Keywords eavesdropping; Melospiza melodia; passerine; social learning; song acoustics; song learning; song repertoire; song sparrow; vocal communication
Abstract (up) Bird song learning is a major model system for the study of learning with many parallels to human language development. In this experiment we examined a critical but poorly understood aspect of song learning: its social context. We compared how much young song sparrows, Melospiza melodia, learned from two kinds of adult `song tutors': one with whom the subject interacted vocally, and one whom the subject only overheard singing with another young bird. We found that although subjects learned from both song models, they learned more than twice as many songs from the overheard tutor. These results provide the first evidence that young birds choose their songs by eavesdropping on interactions, and in some cases may learn more by eavesdropping than by direct interaction.

Title Social referencing and cat–human communication Type Journal Article
Year 2015 Publication Animal Cognition Abbreviated Journal Anim. Cogn.
Volume 18 Issue 3 Pages 639-648
Keywords Social referencing; Cats; Gaze alternation; Social learning; Human–cat communication
Abstract (up) Cats’ (Felis catus) communicative behaviour towards humans was explored using a social referencing paradigm in the presence of a potentially frightening object. One group of cats observed their owner delivering a positive emotional message, whereas another group received a negative emotional message. The aim was to evaluate whether cats use the emotional information provided by their owners about a novel/unfamiliar object to guide their own behaviour towards it. We assessed the presence of social referencing, in terms of referential looking towards the owner (defined as looking to the owner immediately before or after looking at the object), the behavioural regulation based on the owner’s emotional (positive vs negative) message (vocal and facial), and the observational conditioning following the owner’s actions towards the object. Most cats (79 %) exhibited referential looking between the owner and the object, and also to some extent changed their behaviour in line with the emotional message given by the owner. Results are discussed in relation to social referencing in other species (dogs in particular) and cats’ social organization and domestication history.

Title Chimpanzees differentially produce novel vocalizations to capture the attention of a human Type Journal Article
Year 2007 Publication Animal Behaviour. Abbreviated Journal Anim. Behav.
Volume 73 Issue 2 Pages 281-286
Keywords acoustic signals; chimpanzee; cognition; Pan troglodytes; vocal communication
Abstract (up) Chimpanzees, Pan troglodytes, produce numerous species-atypical signals when raised in captivity. We examined contextual elements of the use of two of these vocal signals, the `raspberry' and the extended grunt. Our results demonstrate that these vocalizations are not elicited by the presence of food, but instead function as attention-getting signals. These findings reveal a heretofore underappreciated category of animal signals: attention-getting sounds produced in novel environmental circumstances. The invention and use of species-atypical signals, considered in relation to group differences in signalling repertoires in apes in their natural habitats, may index a generative capacity in these hominoid species without obvious corollary in other primate species.

Title Communication networks: social environments for receiving and signalling behaviour Type Journal Article
Year 2000 Publication Acta ethologica Abbreviated Journal Acta. Ethol.
Volume 2 Issue 2 Pages 71-81
Keywords Communication ? Network ? Eavesdropping ? Audiences ? Information
Abstract (up) Communication and social behaviour are inextricably linked, with communication mediating important social behaviours such as resource defence and mate attraction. However, the social environment in which communication occurs is often ignored in discussions of communication behaviour. We argue that networks of several individuals are the common social environment for communication behaviour. The consequences for receivers and signallers of communicating in a network environment are the main subjects of this review. Eavesdropping is a receiving behaviour that is only possible in the environment of a network and therefore we concentrate on this behaviour. The main effect of communication networks on signallers is to create competition with other signallers for receiver attention. We discuss the consequences of such competition. To conclude, we explore the role of signals and signalling interactions as sources of information that animals exploit to direct their behaviour.

Title Cooperation in primates: Critical analysis of behavioural criteria Type Journal Article
Year 1995 Publication Behavioural Processes Abbreviated Journal Behav. Process.
Volume 35 Issue 1-3 Pages 101-111
Keywords Cognition; Communication; Cooperation; Evolution; Primates
Abstract (up) Concerning hunting in chimpanzees, cooperation has generally been attributed to the behaviour of two or more individuals acting together to achieve a common goal (Boesch and Boesch, 1989). The common goal is often considered as the concrete result of a common action by two or several individuals. Although this result could be used as a criterion for cooperation, it could also be an outcome due to chance. We suggest that the goal, viewed as a concrete benefit shared by the partners, is not a requisite of cooperation but rather a possible consequence of a common action largely submitted to social constraints. Individuals engaged in a cooperative task in order to solve a problem have to exchange information to adjust to each other's behaviour. However, evidence of communication between partners during simultaneous cooperation is rare. An experiment in which two chimpanzees each had to simultaneously pull a handle to get a fruit was performed. We analysed not only the concrete result of the partners' activity but also what the individuals took into account before pulling a handle. We tried to specify what the chimpanzees learned by means of a series of logical propositions which we were able to confront the experimental results.

Title Response of female cuttlefish Sepia officinalis (Cephalopoda) to mirrors and conspecifics: evidence for signaling in female cuttlefish Type Journal Article
Year 2006 Publication Animal cognition Abbreviated Journal Anim. Cogn.
Volume 9 Issue 2 Pages 151-155
Keywords Analysis of Variance; *Animal Communication; Animals; Bias (Epidemiology); Female; Male; Pigmentation/*physiology; Recognition (Psychology)/*physiology; Sepia/*physiology; Visual Perception/*physiology
Abstract (up) Cuttlefish have a large repertoire of body patterns that are used for camouflage and interspecific signaling. Intraspecific signaling by male cuttlefish has been well documented but studies on signaling by females are lacking. We found that females displayed a newly described body pattern termed Splotch toward their mirror image and female conspecifics, but not to males, prey or inanimate objects. Female cuttlefish may use the Splotch body pattern as an intraspecific signal, possibly to reduce agonistic interactions. The ability of females to produce a consistent body pattern in response to conspecifics and mirrors suggests that they can recognize same-sex conspecifics using visual cues, despite the lack of sexual dimorphism visible to human observers.

Title The use of experimenter-given cues by South African fur seals (Arctocephalus pusillus) Type Journal Article
Year 2004 Publication Animal Cognition Abbreviated Journal Anim. Cogn.
Volume 7 Issue 4 Pages 224-230
Keywords Animal Communication; Animals; *Association Learning; *Cues; Female; Fur Seals/*psychology; *Gestures; Humans; *Imitative Behavior; Nonverbal Communication; Social Behavior; Species Specificity
Abstract (up) Dogs can use a variety of experimenter-given cues such as pointing, head direction, and eye direction to locate food hidden under one of several containers. Some authors have proposed that this is a result of the domestication process. In this study we tested four captive fur seals in a two alternative object choice task in which subjects had to use one of the following experimenter-given cues to locate the food: (1) the experimenter pointed and gazed at one of the objects, (2) the experimenter pointed at only one of the objects, (3) the experimenter gazed at only one of the objects, (4) the experimenter glanced at only one of the objects, (5) the experimenter pointed and gazed at one of the objects but was sitting closer to one object than to the other, (6) the experimenter pointed only with the index finger at one of the objects, (7) the experimenter presented a replica of one of the objects. The fur seals were able to use cues which involved a fully exposed arm or a head direction, but failed to use glance only, the index finger pointing and the object replica cues. The results showed that a domestication process was not necessary to develop receptive skills to cues given by an experimenter. Instead, we hypothesize that close interactions with humans prior to testing enabled fur seals to uses ome gestural cues without formal training. We also analyzed the behavior of the seals depending on the level of difficulty of the task. Behavioral signs of hesitation increased with task difficulty. This suggests that the fur seals were sensitive to task difficulty.

Title Domestic dogs (Canis familiaris) use a physical marker to locate hidden food Type Journal Article
Year 2006 Publication Animal Cognition Abbreviated Journal Anim. Cogn.
Volume 9 Issue 1 Pages 27-35
Keywords Animals; Cues; Dogs/*psychology; Female; Gestures; Humans; Male; *Nonverbal Communication; *Recognition (Psychology); Signal Detection (Psychology); Visual Perception
Abstract (up) Dogs can use the placement of an arbitrary marker to locate hidden food in an object-choice situation. We tested domestic dogs (Canis familiaris) in three studies aimed at pinning down the relative contributions of the human's hand and the marker itself. We baited one of two cups (outside of the dogs' view) and gave the dog a communicative cue to find the food. Study 1 systematically varied dogs' perceptual access to the marker placing event, so that dogs saw either the whole human, the hand only, the marker only, or nothing. Follow-up trials investigated the effect of removing the marker before the dog's choice. Dogs used the marker as a communicative cue even when it had been removed prior to the dog's choice and attached more importance to this cue than to the hand that placed it although the presence of the hand boosted performance when it appeared together with the marker. Study 2 directly contrasted the importance of the hand and the marker and revealed that the effect of the marker diminished if it had been associated with both cups. In contrast touching both cups with the hand had no effect on performance. Study 3 investigated whether the means of marker placement (intentional or accidental) had an effect on dogs' choices. Results showed that dogs did not differentiate intentional and accidental placing of the marker. These results suggest that dogs use the marker as a genuine communicative cue quite independently from the experimenter's actions.

Title Dogs respond appropriately to cues of humans' attentional focus Type Journal Article
Year 2004 Publication Behavioural Processes Abbreviated Journal Behav. Process.
Volume 66 Issue 2 Pages 161-172
Keywords Animals; *Attention; Bonding, Human-Pet; Communication; *Cues; Dogs; Humans; Recognition (Psychology)
Abstract (up) Dogs' ability to recognise cues of human visual attention was studied in different experiments. Study 1 was designed to test the dogs' responsiveness to their owner's tape-recorded verbal commands (Down!) while the Instructor (who was the owner of the dog) was facing either the dog or a human partner or none of them, or was visually separated from the dog. Results show that dogs were more ready to follow the command if the Instructor attended them during instruction compared to situations when the Instructor faced the human partner or was out of sight of the dog. Importantly, however, dogs showed intermediate performance when the Instructor was orienting into 'empty space' during the re-played verbal commands. This suggests that dogs are able to differentiate the focus of human attention. In Study 2 the same dogs were offered the possibility to beg for food from two unfamiliar humans whose visual attention (i.e. facing the dog or turning away) was systematically varied. The dogs' preference for choosing the attentive person shows that dogs are capable of using visual cues of attention to evaluate the human actors' responsiveness to solicit food-sharing. The dogs' ability to understand the communicatory nature of the situations is discussed in terms of their social cognitive skills and unique evolutionary history.

Title Making inferences about the location of hidden food: social dog, causal ape Type Journal Article
Year 2006 Publication Journal of comparative psychology Abbreviated Journal J Comp Psychol
Volume 120 Issue 1 Pages 38-47
Keywords Animals; Communication; Cues; Dogs; Exploratory Behavior; *Feeding Behavior; Female; *Food; Male; Pan paniscus; Pan troglodytes; *Visual Perception
Abstract (up) Domestic dogs (Canis familiaris) and great apes from the genus Pan were tested on a series of object choice tasks. In each task, the location of hidden food was indicated for subjects by some kind of communicative, behavioral, or physical cue. On the basis of differences in the ecologies of these 2 genera, as well as on previous research, the authors hypothesized that dogs should be especially skillful in using human communicative cues such as the pointing gesture, whereas apes should be especially skillful in using physical, causal cues such as food in a cup making noise when it is shaken. The overall pattern of performance by the 2 genera strongly supported this social-dog, causal-ape hypothesis. This result is discussed in terms of apes' adaptations for complex, extractive foraging and dogs' adaptations, during the domestication process, for cooperative communication with humans.
