Apes save tools for future use | Type | Journal Article | ||

| Abstract | Planning for future needs, not just current ones, is one of the most formidable human cognitive achievements. Whether this skill is a uniquely human adaptation is a controversial issue. In a study we conducted, bonobos and orangutans selected, transported, and saved appropriate tools above baseline levels to use them 1 hour later (experiment 1). Experiment 2 extended these results to a 14-hour delay between collecting and using the tools. Experiment 3 showed that seeing the apparatus during tool selection was not necessary to succeed. These findings suggest that the precursor skills for planning for the future evolved in great apes before 14 million years ago, when all extant great ape species shared a common ancestor. | ||||

Dominance and affiliation mediate despotism in a social primate | Type | Journal Article | ||
| Year | 2008 | Publication | Current Biology : CB | Abbreviated Journal | Curr Biol |
| Volume | 18 | Issue | 23 | Pages | 1833-1838 |
| Keywords | Animals; *Authoritarianism; Behavior, Animal/*physiology; Cooperative Behavior; *Decision Making; Feeding Behavior; Female; *Group Processes; Male; Papio ursinus/*psychology; *Social Dominance | ||||
| Abstract | Group-living animals routinely have to reach a consensus decision and choose between mutually exclusive actions in order to coordinate their activities and benefit from sociality. Theoretical models predict “democratic” rather than “despotic” decisions to be widespread in social vertebrates, because they result in lower “consensus costs”-the costs of an individual foregoing its optimal action to comply with the decision-for the group as a whole. Yet, quantification of consensus costs is entirely lacking, and empirical observations provide strong support for the occurrence of both democratic and despotic decisions in nature. We conducted a foraging experiment on a wild social primate (chacma baboons, Papio ursinus) in order to gain new insights into despotic group decision making. The results show that group foraging decisions were consistently led by the individual who acquired the greatest benefits from those decisions, namely the dominant male. Subordinate group members followed the leader despite considerable consensus costs. Follower behavior was mediated by social ties to the leader, and where these ties were weaker, group fission was more likely to occur. Our findings highlight the importance of leader incentives and social relationships in group decision-making processes and the emergence of despotism. | ||||

Energy expenditure of horse riding | Type | Journal Article | ||
| Year | 2000 | Publication | European Journal of Applied Physiology | Abbreviated Journal | Eur J Appl Physiol |
| Volume | 82 | Issue | 5-6 | Pages | 499-503 |
| Keywords | Adult; Animals; Energy Metabolism/*physiology; Exercise/*physiology; Exercise Test; Female; Hemodynamic Processes/physiology; Horses; Humans; Male; Oxygen Consumption/physiology; Respiratory Mechanics/physiology | ||||
| Abstract | Oxygen consumption (VO2), ventilation (VE) and heart rate (HR) were studied in five recreational riders with a portable oxygen analyser (K2 Cosmed, Rome) telemetric system, during two different experimental riding sessions. The first one was a dressage session in which the rider successively rode four different horses at a walk, trot and canter. The second one was a jumping training session. Each rider rode two horses, one known and one unknown. The physiological parameters were measured during warm up at a canter in suspension and when jumping an isolated obstacle at a trot and canter. This session was concluded by a jumping course with 12 obstacles. The data show a progressive increase in VO2 during the dressage session from a mean value of 0.70 (0.18) l x min(-1) [mean (SD)] at a walk, to 1.47 (0.28) l x min(-1) at a trot, and 1.9 (0.3) l x min(-1) at a canter. During the jumping session, rider VO2 was 2 (0.33) l x min(-1) with a mean HR of 155 beats x min(-1) during canter in suspension, obstacle trot and obstacle canter. The jumping course significantly enhanced VO2 and HR up to mean values of 2.40 (0.35) l x min(-1) and 176 beats x min(-1), respectively. The comparison among horses and riders during the dressage session shows differences in energy expenditure according to the horse for the same rider and between riders. During the jumping session, there was no statistical difference between riders riding known and unknown horses. In conclusion these data confirm that riding induces a significant increase in energy expenditure. During jumping, a mean value of 75% VO2max was reached. Therefore, a good aerobic capacity seems to be a factor determining riding performance in competitions. Regular riding practice and additional physical training are recommended to enhance the physical fitness of competitive riders. | ||||

Equine learning behaviour | Type | Journal Article | ||
| Year | 2007 | Publication | Behavioural Processes | Abbreviated Journal | Behav. Process. |
| Volume | 76 | Issue | 1 | Pages | 1-13 |
| Keywords | Horse; Behaviour; Learning; Processes; Memory | ||||
| Abstract | Scientists and equestrians continually seek to achieve a clearer understanding of equine learning behaviour and its implications for training. Behavioural and learning processes in the horse are likely to influence not only equine athletic success but also the usefulness of the horse as a domesticated species. However given the status and commercial importance of the animal, equine learning behaviour has received only limited investigation. Indeed most experimental studies on equine cognitive function to date have addressed behaviour, learning and conceptualisation processes at a moderately basic cognitive level compared to studies in other species. It is however, likely that the horses with the greatest ability to learn and form/understand concepts are those, which are better equipped to succeed in terms of the human-horse relationship and the contemporary training environment. Within equitation generally, interpretation of the behavioural processes and training of the desired responses in the horse are normally attempted using negative reinforcement strategies. On the other hand, experimental designs to actually induce and/or measure equine learning rely almost exclusively on primary positive reinforcement regimes. Employing two such different approaches may complicate interpretation and lead to difficulties in identifying problematic or undesirable behaviours in the horse. The visual system provides the horse with direct access to immediate environmental stimuli that affect behaviour but vision in the horse is of yet not fully investigated or understood. Further investigations of the equine visual system will benefit our understanding of equine perception, cognitive function and the subsequent link with learning and training. More detailed comparative investigations of feral or free-ranging and domestic horses may provide useful evidence of attention, stress and motivational issues affecting behavioural and learning processes in the horse. The challenge for scientists is, as always, to design and commission experiments that will investigate and provide insight into these processes in a manner that withstands scientific scrutiny. | ||||

Global-feature classification can be acquired more rapidly than local-feature classification in both humans and pigeons | Type | Journal Article | ||
| Year | 2004 | Publication | Animal Cognition | Abbreviated Journal | Anim. Cogn. |
| Volume | 7 | Issue | 2 | Pages | 109-113 |
| Keywords | Adult; Animals; Behavior, Animal/physiology; *Classification; Columbidae/*physiology; *Discrimination Learning; Form Perception; Humans; *Mental Processes; *Pattern Recognition, Visual; Species Specificity | ||||
| Abstract | When humans process visual stimuli, global information often takes precedence over local information. In contrast, some recent studies have pointed to a local precedence effect in both pigeons and nonhuman primates. In the experiment reported here, we compared the speed of acquisition of two different categorizations of the same four geometric figures. One categorization was on the basis of a local feature, the other on the basis of a readily apparent global feature. For both humans and pigeons, the global-feature categorization was acquired more rapidly. This result reinforces the conclusion that local information does not always take precedence over global information in nonhuman animals. | ||||

Group decision-making in animals | Type | Journal Article | ||
| Year | 2003 | Publication | Nature | Abbreviated Journal | Nature |
| Volume | 421 | Issue | 6919 | Pages | 155-158 |
| Keywords | Animals; Behavior, Animal/*physiology; *Decision Making; Democracy; Group Processes; *Models, Biological; Population Density; Social Behavior | ||||
| Abstract | Groups of animals often need to make communal decisions, for example about which activities to perform, when to perform them and which direction to travel in; however, little is known about how they do so. Here, we model the fitness consequences of two possible decision-making mechanisms: 'despotism' and 'democracy'. We show that under most conditions, the costs to subordinate group members, and to the group as a whole, are considerably higher for despotic than for democratic decisions. Even when the despot is the most experienced group member, it only pays other members to accept its decision when group size is small and the difference in information is large. Democratic decisions are more beneficial primarily because they tend to produce less extreme decisions, rather than because each individual has an influence on the decision per se. Our model suggests that democracy should be widespread and makes quantitative, testable predictions about group decision-making in non-humans. | ||||

Group size and cognitive processes | Type | Journal Article | ||
| Year | 2007 | Publication | Applied Animal Behaviour Science | Abbreviated Journal | Appl. Anim. Behav. Sci. |
| Volume | 103 | Issue | 3-4 | Pages | 15-228 |
| Keywords | Group size; Social complexity; Social learning; Cognitive processes | ||||
| Abstract | Animal group sizes may exert important effects on various cognitive mechanisms. Group size is believed to exert pressures on fundamental brain structures that correlate with the increased social demands placed on animals living in relatively large, complex and dynamic social organizations. There is strong experimental evidence connecting social complexity, social learning and development of other cognitive abilities in a broad range of wild and domesticated animal species. In particular, group size seems to have significant effects on animals? abilities to derive concrete and abstract relationships. Here, we review the literature pertaining to cognitive processes and behaviours of various animal species relative to group size, with emphasis on social learning. It is suggested that understanding the relationship between group size and cognition in animals may yield practical animal management benefits, such as housing and conservation strategies, and may also have implications for improved animal welfare. |

| Abstract | Calcium gluconate was administered to conscious horses at 3 different rates (0.1, 0.2, and 0.4 mg/kg/min for 15 minutes each). Serum calcium concentrations and parameters of cardiovascular function were evaluated. All 3 calcium administration rates caused marked increases in both ionized and total calcium concentrations, cardiac index, stroke index, and cardiac contractility (dP/dtmax). Mean arterial pressure and right atrial pressure were unchanged; heart rate decreased markedly during calcium administration. Ionized calcium concentration remained between 54% and 57% of total calcium concentration throughout the study. We conclude that calcium gluconate can safely be administered to conscious horses at 0.1 to 0.4 mg/kg/min and that administration will result in improved cardiac function. | ||||
