Neophobia (the fearful reaction to novel stimuli or situations) has a crucial effect on individual fitness and can vary within and across species. However, the factors predicting this variation are still unclear. In this study, we assessed whether individual characteristics (rank, social integration, sex) and species socio-ecological characteristic...

Background Comparative cognition has historically focused on a few taxa such as primates, birds or rodents. However, a broader perspective is essential to understand how different selective pressures affect cognition in different taxa, as more recently shown in several studies. Here we present the same battery of cognitive tasks to two understudied...

Many species, including humans, rely on an ability to differentiate between quantities to make decisions about social relationships, territories, and food. This study is the first to investigate whether giraffes (Giraffa camelopardalis) are able to select the larger of two sets of quantities in different conditions, and how size and density affect...

The ability to solve novel problems is crucial for individual fitness. However, studies on problem solving are usually done on few taxa, with species with low encephalization quotient being rarely tested. Here, we aimed to study problem solving in a non-domesticated ungulate species, European bison, with two experimental tasks. In the first task, f...
Article
Full-text available
Chimpanzees and humans establish preferences over individuals they may benefit more from through scoring indirect reputation. However, humans prefer prosocial individuals even at their own cost. Giving preference to prosocial reputation over material rewards might have permitted the establishment of cooperative human societies. We tested the evolut...
Data
This is the raw data for the two GLMM analysis we conducted. The first tab shows the choices that chimpanzees made during Conditions 2 and 3 as well as some demographic information about them (i.e. sex, age and type of rearing). The second tab shows the behavior and vocalizations we coded in Conditions 2 and 3 as well as the indication of the perio...

Insight behaviors are adaptive and innovative solutions to problems in the environment. Such responses arise without explicit training, so are considered evidence of higher cognitive abilities, such as reasoning. For example, after the perceptual experience with the landscape the animal infers the best way to approach the goal, which can be shelter...
Article
Humans routinely incur costs when allocating resources and reject distributions judged to be below/over an expected threshold. The Dictator/Ultimatum Games (DG/UG) are two-player games that quantify prosociality and inequity aversion by measuring allocated distributions and rejection thresholds. Although the UG has been administered to chimpanzees...
Article
Full-text available
Although behavior, biology, and ecology of giraffes have been widely studied, little is known about their cognition. Giraffes’ feeding ecology and their fission–fusion social dynamics are comparable with those of chimpanzees (Pan troglodytes), suggesting that they might have complex cognitive abilities. To assess this, we tested 6 captive giraffes...
Article
Many studies have used the string-pulling paradigm in order to assess causal understanding of the physical domain in a great variety of species of birds, primates and other mammals. Another area of interest is how subjects manage to solve these tasks, i.e., through trial-error learning, relying on perceptual cues, or through some kind of insight. I...

Full text view only available here: http://rdcu.be/uE2w Although humans are usually believed to be prosocial, the evolutionary origins of prosociality are largely debated. One hypothesis is that cooperative breeding has been one major precursor to the emergence of prosociality. In vertebrates, however, experimental evidence of prosociality has been...
Conference Paper
Full-text available
Giraffes live in complex social systems and are very selective foragers (Dagg, 2014), and they are therefore good candidates to have complex cognitive skills. However, no study has so far specifically assessed their physical cognition. Here, we tested six giraffes (Giraffa camelopardalis) at Barcelona and Leipzig Zoos in a forced-choice task to ass...
Article
In this study we tested an adult female Martin's spot-nosed monkey in several configurations of the string-pulling paradigm, including six different discrimination problems of patterned strings. Our subject solved almost all of the problems presented. Although she seemed to have a spatial preference in the most complex tasks, she maintained a high...
Article
The cognition of green jays (Cyanocorax yncas), a non Corvus corvid species, was investigated by using the string-pulling paradigm. Five adult green jays performed a vertical string-pulling task in which they had to retrieve a worm attached to the end of a vertical hanging string while sitting on their perch. In the first experiment, three of the s...

Fostering moral attitudes at one’s own cost might have permitted the establishment of cooperative societies among humans. However, its evolutionary roots remain unclear. Chimpanzees (Pan troglodytes) behave as rational maximizers although some evidence suggests that they also possess prosocial tendencies. To explore their priorities, we presented t...

Prosociality, reciprocity and inequity aversion shape human cooperation. Their evolutionary roots can be tested through the Ultimatum/Dictator Games (UG/DG). The two studies conducted with chimpanzees (Pan troglodytes) have yielded remarkable contradictory interpretations. In one, chimpanzees behave as rational maximizers, indifferent to conspecifi...
Conference Paper
Prosociality entails behaviours where individuals improve other’s welfare. There is a current debate to evidence which species different from humans show prosociality. In the lab, primates fail to donate food except for some studies in cooperative breeding species, linking this social structure to the emergence of prosociality. We tested this link...
Preprint
The Bornean orangutan (Pongo pygmaeus pygmaeus) is one of the most endangered primates in the world. During the last decades, huge efforts focused on research, in situ and ex situ conservation have been made, by means of studies mainly dealing with behavioural ecology and cognition. Even so, relatively little is known about sociability in captive o...
Article
The ultimatum game is commonly used to explore fairness in adults in bargaining situations. Although the changes in responses that occur during development have been investigated in children, the results have been mixed. Whereas some studies show that proposers offer more when they grow older, others indicate the opposite. Moreover, these studies a...

Full-text available
The aim of our study is to develop a catalog that defines the underlying reasons that lead individuals to commit acts of revenge, which could have significant implications for the prevention of cycles of violence. One of its applications in forensics would be improving risk assessment, both in questionnaires and prison psychological reports about s...

Unsustainable hunting threatens both biodiversity and local livelihoods. Despite high levels of research effort focused on understanding the dynamics of bushmeat trade and consumption, current research is largely site specific. Without synthesis and quantitative analysis of available case studies, the national and regional characteristics of bushme...

Bednekoff, P. A. 2001: Coordination of safe, selfish sentinels based on mutual benefits. — Ann. Zool. Fennici 38: 5–14. Sentinels are group members that watch from prominent positions. Sentinel interchanges often appear orderly and the number of sentinels changes little despite the turnover of individuals. I modeled why solitary individuals or grou...
Article
Recently, many studies have been conducted on manual laterality in chimpanzees. Nevertheless, whether nonhuman primates exhibit population-level handedness remains a topic of considerable debate. One of the behaviors studied has been bimanual coordinated actions. Although recent studies have highlighted that captive chimpanzees show handedness at p...
Article
To maintain a self-sustaining European Endangered Species Programme (EEP) population of Gorillas Gorilla gorilla gorilla, it is necessary that as many individuals as possible contribute their genes to the population. It is believed that hand-rearing may prevent the development of a good repertoire of natural social behaviours that would facilitate...
Conference Paper
Most primates in captivity have not benefited from previous appropriate living conditions, from both a physical and psychological perspective. An appropriate living environment is a prerequisite for the development of primate behavioural strategies to cope with their captive environment. The end result of enduring previous difficult life conditions...
Article
In December 2004, a questionnaire was sent to 44 institutions that maintained Gorillas Gorilla gorilla. Twenty-six institutions replied (59% response rate) providing information about 91 hand-reared Gorillas in the European Endangered Species Programme (EEP) population. Using other sources, such as the international studbook and EEP reports, data o...
Article
Imitation in the great apes continues to be an active field of research and one that is not free of controversy. Several studies suggest that these species do not tend to match the motor movements of the model they observe, but try to achieve the same results using their own methods (emulation of results). In the studies reviewed, gestures have bee...

Animal well-being and enrichment continue to gain importance in the maintenance of primates living in captivity. Positive reinforcement training (PRT) and/or playing interaction have been shown to be effective in improving the well-being of several species of primates. This research study evaluated the effects of applying a combination of these two...
Article
The purpose of this paper is to describe the early introduction protocols developed for four (1.3) hand-reared Gorillas Gorilla gorilla that were introduced to conspecifics at Barcelona Zoo. The introduction process for each was initiated when the infants were <1 year old. The introductions began in 1999 and ended in 2001, and the difficulties face...
Article
Hand-reared cercopithecids may develop inappropriate behaviours and have lower breeding rates. Generally, hand-rearing cercopithecids is not advisable, but when a species in this family is threatened in the wild and its breeding rate in captivity is not enough to ensure a self-sustaining population, hand-rearing could be helpful. In such cases, to...
Article
Various attempts have been made to explain why gorillas (Gorilla gorilla gorilla) find it difficult to recognize their mirror image. One of the most oft-cited reasons is aversion to eye contact, which stops gorillas from looking into a mirror and thus prevents them from carrying out a suitable exploration that could lead to self-recognition. In the...
Article
In this paper the relationship between maternal behaviour and breeding success (or failure) in great apes is described. Data were gathered from a questionnaire survey returned by 48 zoos and from available studbook data, giving a total sample size of 687 individuals [Gorillas Gorilla gorilla (n= 277), Bonobos Pan paniscus (n= 37), Chimpanzees Pan t...

Studies of non-human primate self-recognition in mirrors demonstrate variation both within and between species. This study applied a rigorous methodology that took into account habituation of subjects to the mirror as an object and to the experimental situation. The species observed in our study was Miopithecus talapoin, which has been little studi...
Article
To determine the manual laterality of a sample of 24 chimpanzees, 4 problem apparatuses were used, the solution for which (obtaining a food item) required the use of 1 or both hands in sequential, simultaneous, or both sequential and simultaneous actions. The majority of the subjects showed significant and consistent hand preferences, especially in...
Article
We observed 36 captive great apes [31 chimpanzees (Pan troglodytes),2 bonobos (Pan paniscus), and3 orangutans (Pongo pygmaeus)]reaching for items of food and engaging in other spontaneous behaviors. We consider circumstantial factors that could influence the preferred choice of one hand or the other. Most of the subjects (81%) showed a significant...

A survey in the Lokofe-Ikomaloki area of the Zaire basin yielded 126 visual or auditory contacts with various cercopithecid species. Groups tended to be small (10–12 members on average for most observed species). Data support an influence of body size on the pattern of vertical stratification observed with these species. 59.2% of the groups were in...

Hunting by Bubi villages around Moka, Bioko, and their impact on the local prey fauna was studied during July–August, 1992. Questionnaires were sent to 45 known hunters in the region in order to find out their techniques and hunting procedures. Hunting trips were also followed (a total of 204 km covered) and counts of animals brought to the village...
