| 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 | 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 | Triadic postconflict affiliation in captive chimpanzees: does consolation console? | Type | Journal Article | ||
| Year | 2007 | Publication | Animal Behaviour. | Abbreviated Journal | Anim. Behav. |
| Volume | 73 | Issue | 1 | Pages | 133-142 |
| Keywords | chimpanzee; consolation; Pan troglodytes; postconflict affiliation | ||||
| Abstract | Consolation is a triadic postconflict interaction between a conflict participant and an uninvolved third party. The term consolation implies stress alleviation. Consequently, consolation may be an effective mechanism to alleviate postconflict stress. However, this assumption has not been tested. We tested whether consolation alleviates postconflict stress in captive chimpanzees, Pan troglodytes. In addition, we examined whether consolation is a substitute postconflict interaction for reconciliation. We collected 643 postconflict-matched control pairs on aggressees and 576 on aggressors. Consolation occurred equally frequently with aggressees and aggressors. However, we found no evidence that consolation alleviated stress, regardless of the identity of the consoler. In addition, consolation was also directed to conflict participants with no evident postconflict stress. Furthermore, we found no evidence for consolation being a substitute for reconciliation. The occurrence of consolation did not depend on the occurrence of reconciliation and consolation was not more prevalent with the sex class that reconciled less often or had the highest postconflict stress levels. We conclude that consolation is a postconflict interaction in its own right, the function of which is not likely to be connected to stress alleviation of the consoled individual. We propose that the function of triadic postconflict affiliation, previously labelled as consolation, should be reassessed with regard to the third parties' reasons to affiliate with conflict opponents. | ||||

| Title | Social constraints determine what is learned in the chimpanzee | Type | Journal Article | ||
| Year | 1993 | Publication | Behavioural Processes | Abbreviated Journal | Behav. Process. |
| Volume | 28 | Issue | 3 | Pages | 173-179 |
| Keywords | Operant conditioning; Social influence; Individual strategy; Chimpanzee | ||||
| Abstract | A group of six chimpanzees was placed in a social learning situation, without training. The learning task was an operant conditioning situation; that is, a subject had to pull two handles simultaneously to cause a piece of fruit to fall into the cage. Only three individuals acquired the operant behaviour. For the operant individuals, social influences on the expression of the learning task were then examined; the dominant chimpanzee during feeding had an inhibiting effect when close to the operant subjects. Depending on the subject, social factors may influence not only the specific expression of what is learnt, but also the nature of what is learnt. Chimpanzees appear to experience situations differently: they develop an individual problem-solving strategy according to their social relationships even if the experimental procedure is the same for all. | ||||

| Title | An Experimental Evaluation Of The Consistency Of Competitive Ability And Agonistic Dominance In Different Social Contexts In Captive Bonobos | Type | Journal Article | ||
| Year | 1999 | Publication | Behaviour | Abbreviated Journal | Behaviour |
| Volume | 136 | Issue | 4 | Pages | 423-442 |
| Keywords | BONOBO PAN PANISCUS; RANK ORDERS; FEEDING SCORES; AGONISTIC RANKS; PEERING | ||||
| Abstract | Bonobos have been described as a relatively egalitarian and female dominant species. The exact nature and quality of their dominance relationships and the existence of female dominance are current topics of dispute. We investigated the consistency across social contexts, the stability in time, and the degree of expression of the competitive feeding ability and agonistic dominance in a captive group of bonobos. First, we examined whether the competitive feeding ranks and agonistic ranks differed in different dyadic contexts, triadic contexts and the whole group context. For some pairs of animals the dominance relationships with respect to competitive feeding altered with different group compositions. The agonistic dominance relationships changed accordingly. The competitive feeding ranks and agonistic ranks in the experiments correlated strongly with each other. The alpha position was occupied by a female, but not all females outranked all males. We suggest that females can profit from each others presence to gain inter-sexual dominance. Second, although the agonistic rank order in the whole group remained the same over at least five years, some dyadic competitive feeding ranks changed over time, resulting in a stronger female intersexual dominance. Third, the degree of expression of the behaviors used to quantify dyadic competitive and agonistic dominance was not high, in line with the popular 'egalitarian' epithet. Notwithstanding its low consistency across contexts, the dominance hierarchy in the whole group has a strong predictive value for other social relationships such as grooming. Given this strong effect of rank on other behaviours and given the strong dependency of rank on social context, the choice of the right party members may be a crucial factor in the fission-fusion processes of free-ranging bonobos. | ||||

| Title | Predicting the dynamics of animal behaviour in field populations | Type | Journal Article | ||
| Year | 2007 | Publication | Animal Behaviour. | Abbreviated Journal | Anim. Behav. |
| Volume | 74 | Issue | 1 | Pages | 103-110 |
| Keywords | colony occupancy; differential equation; dynamic modelling; glaucous-winged gull; habitat ecology; Larus glaucescens; mathematical modelling; sleep; territory attendance | ||||
| Abstract | Many species show considerable variation in behaviour among individuals. We show that some behaviours are largely deterministic and predictable with mathematical models. We propose a general differential equation model of behaviour in field populations and use the methodology to explain and predict the dynamics of sleep and colony attendance in seabirds as a function of environmental factors. Our model explained over half the variability in the data to which it was fitted, and it predicted the dynamics of an independent data set. Differential equation models may provide new approaches to the study of behaviour in animals and humans. | ||||

| Title | Personality in the behaviour of great apes: temporal stability, cross-situational consistency and coherence in response | Type | Journal Article | ||
| Year | 2008 | Publication | Animal Behaviour. | Abbreviated Journal | Anim. Behav. |
| Volume | 75 | Issue | 1 | Pages | 99-112 |
| Keywords | behaviour prediction; bonobo; bottom-up approach; chimpanzee; gorilla; individual differences; orang-utan; personality; traits | ||||
| Abstract | Using a multidisciplinary approach, the present study complements ethological behaviour measurements with basic theoretical concepts, methods and approaches of the personality psychological trait paradigm. Its adoptability and usefulness for animal studies are tested exemplarily on a sample of 20 zoo-housed great apes (five of each of the following species): bonobos, Pan paniscus; chimpanzees, Pan troglodytes verus; gorillas, Gorilla gorilla gorilla; and orang-utans, Pongo pygmaeus abelii. Data on 76 single trait-relevant behaviours were recorded in a series of 14 laboratory-based situations and in two different group situations. Data collection was repeated completely after a break of 2 weeks within a 60-day period. All behaviour records were sufficiently reliable. Individual- and variable-oriented analyses showed high/substantial temporal stability on different levels of aggregation. Distinctive and stable individual situational and response profiles clarified the importance of situations and of multiple trait-relevant behaviours. The present study calls for a closer collaboration between behavioural biologists and personality psychologists to tap the full potential of animal personality research. | ||||

| Title | Sharing the motivation to play: the use of signals in adult bonobos | Type | Journal Article | ||
| Year | 2008 | Publication | Animal Behaviour. | Abbreviated Journal | Anim. Behav. |
| Volume | 75 | Issue | 3 | Pages | 887-896 |
| Keywords | bonobo; full play face; Pan paniscus; play face; playful propensity; ritualization; social play; social tolerance; solitary play; visual communication | ||||
| Abstract | Gestures and facial displays are involved in regulating many aspects of mammal social life such as aggression, dominance-subordinate relationships, appeasement and play. Playful activity is an interesting behaviour for examining the role of signals as intentional communication systems. When animals play they perform patterns that are used in other serious contexts. To avoid miscommunication, many species have evolved signals to maintain a playful mood. Bonobos, Pan paniscus, with their flexible social relationships and playful propensity, may represent a good model species to test some hypotheses on adult play signalling. I analysed the potential roles of facial play expressions and solitary play in soliciting and regulating social play and found that adult bonobos used the play face (relaxed open-mouth display) in a selective manner. Play faces were more frequent during social than solitary play and, within social play, polyadic sessions (even though less frequent than dyadic sessions) were characterized by a higher frequency of signals. Following the rule of play intensity matching, play faces were more frequent when the two players matched in age and size (sessions among adults). Moreover, among dyads there was a positive correlation between the frequency of aggressive interactions performed and the frequency of play signals used, thus suggesting that signals are crucial in play negotiations among individuals showing high baseline levels of aggression. Finally, solitary play, especially when it involved pirouettes and somersaults, had an important role in triggering social play. | ||||

| Title | Chimpocentrism: Bias in cognitive ethology | Type | Journal Article | ||
| Year | 1982 | Publication | Journal of Human Evolution | Abbreviated Journal | |
| Volume | 11 | Issue | 1 | Pages | 3-17 |
| Keywords | herring gull; chimpanzee; cognition; tool-use; shell-dropping; mollusk; predation | ||||
| Abstract | Herring gulls drop hard-shelled mollusks and hermit crab-inhabited molluskan prey in order to break the shells and gain access to the edible interior. A field study of predatory shell dropping on Cape Cod, Massachusetts, U.S.A. showed that the gulls usually drop the same shell repeatedly, orient directly to dropping sites that are invisible from the point at which the mollusks are captured, drop preferentially on hard surfaces, adjust dropping heights to suit the area and elasticity of the substrate, orient directly into the wind while dropping, sever the large defensive cheliped of hermit crabs before consumption, and rinse prey that is difficult to swallow. Proficiency in prey dropping is acquired through dropping objects in play, trial-and-error learning, and perhaps, observation learning. Observable attributes of predatory shell-dropping support inferences that the gulls are capable of extended concentration, purposefulness, mental representation of spatially and temporally displaced environmental features, cognitive mapping, cognitive modeling, selectivity, and strategy formation. Identical cognitive processes have been inferred to underlie the most sophisticated forms of chimpanzee tool-use. Advanced cognitive capacities are not restricted to chimpanzees and other pongids, and are not associated uniquely with tool use. The chimpocentric bias should be abandoned, and reconstructions of the evolution of intelligence should be modified accordingly. |

| Abstract | This volume brings together studies from various disciplines of the social sciences and humanities (Anthropology, Sociology, Cultural Studies, History and Literary theory) that examine the equestrian world as a historically gendered and highly dynamic field of contemporary sport and culture. From elite international dressage and jumping, polo and the turf, to the rodeo world of the Americas and popular forms of equestrian sport and culture, we are introduced to a range of issues as they unfold at local and global, national and international levels. Students and scholars of gender, culture and sport will find much of interest in this original look at contemporary issues such as “engendered” (women’s and men’s) dentities/subjectivities of equestrians, representations of girls, horses and the world of adventure in juvenile fiction; the current “feminization” of particular equestrian activities (and where boys and men stand in relation to this); how broad forms of social inequality and stratification play themselves out within gendered equestrian contexts; men and women and their relation to horses within the framework of current discussions on the relation of animals to humans (which may include not only love and care, but also exploitation and violence), among others. Singular contributions that incorporate a wide variety of classic and contemporary theoretical perspectives and empirical methodologies show how horse cultures around the globe contribute to historical and current constructions of embodied “femininities” and “masculinities”, reflecting a world that has been moving “beyond the binaries” while continuing to be enmeshed in their persistent and contradictory legacy. The final chapter makes a brave attempt at synthesizing individual chapters and moving forward from the evidences they provide, to suggest a compelling agenda for future research. | ||||
