Do Asian elephants (Elephas maximus) apply causal reasoning to tool-use tasks? | Type | Journal Article | ||

| Abstract | Two experiments addressed contradictory claims about causal reasoning in elephants. In Experiment 1, 4 Asian elephants (Elephas maximus) were pretrained to remove a lid from the top of a bucket and retrieve a food reward. Subsequently, in the first 5 critical trials, when the lid was placed alongside the bucket and no longer obstructed access to the reward, each elephant continued to remove the lid before retrieving the reward. Experiment 2, which involved 11 additional elephants and variations of the original design, yielded similarly counterintuitive observations. Although the results are open to alternative interpretations, they appear more consistent with associative learning than with causal reasoning. Future applications of Fabrean methodologies (J. H. Fabre, 1915) to animal cognition are proposed. | ||||

Do minds exist in species other than our own? | Type | Journal Article | ||

| Abstract | An answer to the question of animal awareness depends on evidence, not intuition, anecdote, or debate. This paper examines some of the problems inherent in an analysis of animal awareness, and whether animals might be aware of being aware is offered as a more meaningful distinction. A framework is presented which can be used to make a determination about the extent to which other species have experiences similar to ours based on their ability to make inferences and attributions about mental states in others. The evidence from both humans and animals is consistent with the idea that the capacity to use experience to infer the experience of others is a byproduct of self-awareness. | ||||

Does attention make the difference? Horses' response to human stimulus after 2 different training strategies | Type | Journal Article | ||
| Year | 2011 | Publication | Journal of Veterinary Behavior: Clinical Applications and Research | Abbreviated Journal | J Vet Behav Clin Appl Res |
| Volume | 6 | Issue | 1 | Pages | 31-38 |
| Keywords | attention; exploration; horse; human stimulus; training | ||||
| Abstract | We hypothesized that in an open environment, horses cope with a series of challenges in their interactions with human beings. If the horse is not physically constrained and is free to move in a small enclosure, it has additional options regarding its behavioral response to the trainer. The aim of our study was to evaluate the influence of 2 different training strategies on the horse’s behavioral response to human stimuli. In all, 12 female ponies were randomly divided into the following 2 groups: group A, wherein horses were trained in a small enclosure (where indicators of the level of attention and behavioral response were used to modulate the training pace and the horse’s control over its response to the stimuli provided by the trainer) and group B, wherein horses were trained in a closed environment (in which the trainer’s actions left no room for any behavioral response except for the one that was requested). Horses’ behavior toward the human subject and their heart rate during 2 standardized behavioral tests were used to compare the responses of the 2 groups. Results indicated that the horses in group A appeared to associate human actions with a positive experience, as highlighted by the greater degree of explorative behavior toward human beings shown by these horses during the tests. The experience of the horses during training may have resulted in different evaluations of the person, as a consequence of the human’s actions during training; therefore, it seems that horses evaluate human beings on daily relationship experiences. |

Domesticated horses differ in their behavioural and physiological responses to isolated and group housing | Type | Journal Article | ||
| Year | 2015 | Publication | Physiology & Behavior | Abbreviated Journal | Physiol.Behav. |
| Volume | 143 | Issue | Pages | 51-57 | |
| Keywords | Equine; Behaviour; Corticosterone; Housing | ||||
| Abstract | Abstract The predominant housing system used for domestic horses is individual stabling; however, housing that limits social interaction and requires the horse to live in semi-isolation has been reported to be a concern for equine welfare. The aim of the current study was to compare behavioural and physiological responses of domestic horses in different types of housing design that provided varying levels of social contact. Horses (n = 16) were divided equally into four groups and exposed to each of four housing treatments for a period of five days per treatment in a randomized block design. The four housing treatments used were single housed no physical contact (SHNC), single housed semi-contact (SHSC), paired housed full contact (PHFC) and group housed full contact (GHFC). During each housing treatment, adrenal activity was recorded using non-invasive faecal corticosterone metabolite analysis (fGC). Thermal images of the eye were captured and eye temperature was assessed as a non-invasive measure of the stress response. Behavioural analysis of time budget was carried out and an ease of handling score was assigned to each horse in each treatment using video footage. SHNC horses had significantly higher (p = 0.01) concentrations of fGC and were significantly (p = 0.003) more difficult to handle compared to the other housing types. GHFC horses, although not significantly different, had numerically lower concentrations of fGC and were more compliant to handling when compared to all other housing treatments. Eye temperature was significantly (p = 0.0001) lower in the group housed treatment when compared to all other treatments. These results indicate that based on physiological and behavioural measures incorporating social contact into the housing design of domestic horses could improve the standard of domestic equine welfare. | ||||

Dominance, aggression and physiological stress in wild male Assamese macaques (Macaca assamensis) | Type | Journal Article | ||
| Year | 2008 | Publication | Hormones and Behavior | Abbreviated Journal | |
| Volume | 54 | Issue | 5 | Pages | 613-619 |
| Keywords | Social stress; Dominance; Aggression; Fecal glucocorticoid excretion; Male bonds; Assamese macaques | ||||
| Abstract | In group-living animals relative rank positions are often associated with differences in glucocorticoid output. During phases of social stability, when dominance positions are clear and unchallenged, subordinates often face higher costs in terms of social stress than dominant individuals. In this study we test this prediction and examine additional potential correlates of stress, such as reproductive season, age and amount of aggression received in wild, seasonally breeding Assamese macaques (Macaca assamensis). During a mating and a non-mating season we collected 394 h of focal observational data and 440 fecal samples of six adult and six large subadult males living in a multimale-multifemale group in their natural habitat in northeastern Thailand. The mating season was characterized by a general increase in aggressive behavior and glucocorticoid excretion across all males compared to the non-mating season. Among adult males, mating season glucocorticoid levels were significantly negatively related with dominance rank and positively with the amount of aggression received. Both relationships were non-significant among large subadult males. Thus, our results suggest that in adult Assamese macaques a high dominance position is not associated with high costs. Low costs of dominance might be induced by strong social bonds among top-ranking males, which exchange frequent affiliative interactions and serve as allies in coalitionary aggression against potentially rank-challenging subordinate males. | ||||

Dominance, leadership, and aggression: animal behavior studies during the Second World War | Type | Journal Article | ||
| Year | 1990 | Publication | Journal of the History of the Behavioral Sciences | Abbreviated Journal | J Hist Behav Sci |
| Volume | 26 | Issue | 1 | Pages | 3-16 |
| Keywords | *Aggression; Animals; Behavior, Animal; *Dominance-Subordination; History, 20th Century; *Leadership; Political Systems; *Social Dominance; United States | ||||
| Abstract | During the decade surrounding the Second World War, an extensive literature on the biological and psychological basis of aggression surfaced in America, a literature that in general emphasized the significance of learning and environment in the origins of aggressive behavior. Focusing on the animal behavior research of Warder Clyde Allee and John Paul Scott, this paper examines the complex interplay among conceptual, institutional, and societal forces that created and shaped a discourse on the subjects of aggression, dominance, and leadership within the context of World War II. The distinctions made between sexual and social dominance during this period, distinctions accentuated by the threat of totalitarianism abroad, and the varying ways that interpretations of behavior could be negotiated attests to the multiplicity of interactions that influence the development of scientific research. | ||||

Dynamics of the TIT FOR TAT strategy during predator inspection in the guppy (Poecilia reticulata) | Type | Journal Article | ||

| Volume | 29 | Issue | 2 | Pages | 127-132 |
| Keywords | |||||
| Abstract | One well-known solution to the iterated Prisoner's Dilemma is the TIT FOR TAT strategy. This strategy has three “characteristics” associated with it. TIT FOR TAT is nice (cooperates on the first move of a game), retaliatory (plays defect against an individual that defected on the prior move), and forgiving (cooperates with an individual which has defected in the past but cooperates in the present). Predator inspection behavior in guppies (Poecilia reticulata) was examined in order to determine whether guppies displayed these three characteristics. Results indicate that while it can be quite difficult to translate the abstract concepts of niceness, retaliation, and forgiveness into measurable behaviors, the data support the hypothesis that guppies display the three characteristics associated with the TIT FOR TAT strategy. | ||||

Ecology, feeding competition and social structure in baboons | Type | Journal Article | ||
| Year | 1996 | Publication | Behavioral Ecology and Sociobiology | Abbreviated Journal | Behav. Ecol. Sociobiol. |
| Volume | 38 | Issue | 5 | Pages | 321-329 |
| Keywords | Key words Ecology – Competition – Group size – Baboons | ||||
| Abstract | Predictions of the model of van Schaik (1989) of female-bonding in primates are tested by systematically comparing the ecology, level of within-group contest competition for food (WGC), and patterns of social behaviour found in two contrasting baboon populations. Significant differences were found in food distribution (percentage of the diet from clumped sources), feeding supplant rates and grooming patterns. In accord with the model, the tendencies of females to affiliate and form coalitions with one another, and to be philopatric, were strongest where ecological conditions promoted WGC. Group fission in the population with strong WGC was “horizontal” with respect to female dominance rank, and associated with female-female aggression during a period of elevated feeding competition. In contrast, where WGC was low, females' grooming was focused on adult males rather than other females. Recent evidence suggests that group fission here is initiated by males, tends to result in the formation of one-male groups, and is not related to feeding competition but to male-male competition for mates. An ecological model of baboon social structure is presented which incorporates the effects of female-female competition, male-male competition, and predation pressure. The model potentially accounts for wide variability in group size, group structure and social relationships within the genus Papio. Socio-ecological convergence between common baboons and hamadryas baboons, however, may be limited in some respects by phylogenetic inertia. | ||||

Effect of meal frequency on fluid balance and behavior of ponies | Type | Journal Article | ||
| Year | 1988 | Publication | Physiology & behavior | Abbreviated Journal | Physiol. Behav. |
| Volume | 42 | Issue | 5 | Pages | 401-407 |
| Keywords | Animals; Behavior, Animal/*physiology; Blood Proteins/analysis; *Eating; Female; Hematocrit; Horses/blood/*physiology; Osmolar Concentration; *Water-Electrolyte Balance | ||||
| Abstract | Twelve ponies were fed their total daily ration either as one large meal or divided into six small meals. Pre- and post-feeding behavior was recorded six times a day. Blood samples were taken for 30 min before and two hr after the meal. Plasma protein increased from 7.0 to a peak of 7.3 g/dl with small meals and from 7.3 to 8.1 g/dl with large meals, and returned to pre-feeding levels by 90 min post-feeding. Hematocrit rose from 33.3 to 34.1% with small meals and from 33.0 to 36.0% with large meals. These rapid and short-lived increases indicate a decrease in plasma volume. Plasma osmolality rose with feeding from 283 to 285 mosmoles/kg with small meals and from 281 to 288 mosmoles/kg with large meals. Water availability had no significant effect on blood changes. Digestibility and rate of passage were measured with chromic oxide, but there were no differences. Vocalizing (neighing) and walking occurred more often before than after feeding, while eating bedding and engaging in other oral behaviors were more frequent after feeding. | ||||
