  Title Spatial cognition and perseveration by horses, donkeys and mules in a simple A-not-B detour task Type Journal Article
  Year 2013 Publication (up) Abbreviated Journal Animal Cognition  
  Volume 16 Issue 2 Pages 301-305  
  Keywords Equids; Donkeys; Horses; Mules; Dogs; Detour; Spatial reasoning; A-not-B; Perseveration  
  Abstract We investigated perseveration and detour behaviour in 36 equids (Equus caballus, E. asinus, E. caballus × E. asinus) and compared these data to those of a previous study on domestic dogs (Canis familiaris). The animals were required to make a detour through a gap at one end of a straight barrier in order to reach a visible target. After one, two, three or four repeats (A trials), the gap was moved to the opposite end of the barrier (B trials). We recorded initial deviations from the correct solution path and the latency to crossing the barrier. In the A trials, mules crossed the barrier significantly faster than their parental species, the horses and donkeys. In the B trials, following the change of gap location, all species showed a reduction in performance. Both dogs and horses exhibited significant spatial perseveration, going initially to the previous gap location. Donkeys and mules, however, performed at chance level. Our results suggest that hybrid vigour in mules extends to spatial abilities.

  Title Experimental evidence for action imitation in killer whales (Orcinus orca) Type Journal Article
  Year 2013 Publication (up) Abbreviated Journal Animal Cognition  
  Volume 16 Issue 1 Pages 11-22  
  Keywords Social learning; Imitation; ‘Do-as-other-does’ test; Animal culture; Killer whales  
  Abstract Comparative experimental studies of imitative learning have focused mainly on primates and birds. However, cetaceans are promising candidates to display imitative learning as they have evolved in socioecological settings that have selected for large brains, complex sociality, and coordinated predatory tactics. Here we tested imitative learning in killer whales, Orcinus orca. We used a ‘do-as-other-does’ paradigm in which 3 subjects witnessed a conspecific demonstrator’s performance that included 15 familiar and 4 novel behaviours. The three subjects (1) learned the copy command signal ‘Do that’ very quickly, that is, 20 trials on average; (2) copied 100 % of the demonstrator’s familiar and novel actions; (3) achieved full matches in the first attempt for 8–13 familiar behaviours (out of 15) and for the 2 novel behaviours (out of 2) in one subject; and (4) took no longer than 8 trials to accurately copy any familiar behaviour, and no longer than 16 trials to copy any novel behaviour. This study provides experimental evidence for body imitation, including production imitation, in killer whales that is comparable to that observed in dolphins tested under similar conditions. These findings suggest that imitative learning may underpin some of the group-specific traditions reported in killer whales in the field.

  Title Taking personality selection bias seriously in animal cognition research: a case study in capuchin monkeys (Sapajus apella) Type Journal Article
  Year 2013 Publication (up) Abbreviated Journal Animal Cognition  
  Volume 16 Issue 4 Pages 677-684  
  Keywords Platyrrhines; Temperament; Cognitive experiment; Selection bias; Associative learning; Training  
  Abstract In most experimental work on animal cognition, researchers attempt to control for multiple interacting variables by training subjects prior to testing, allowing subjects to participate voluntarily, and providing subjects with food rewards. However, do such methods encourage selection bias from subjects’ personalities? In this study, we trained eighteen zoo-housed capuchin monkeys (Sapajus apella) for two experiments, under conditions of positive reinforcement (i.e. food rewards) and free-choice participation. Using a combination of behavioral and rater-based methods, we identified and validated five personality dimensions in these capuchins (Assertiveness, Openness, Neuroticism, Sociability, and Attentiveness). Scores on Openness were positively related to individual differences in monkey task participation, reflecting previous work showing that such individuals are often more active, curious, and willing to engage in testing. We also found a negative relationship between scores on Assertiveness and performance on tasks, which may reflect the trade-offs between speed and accuracy in these animals’ decision-making. Highly Assertive individuals (the most sociable within monkey groups) may also prioritize social interactions over engaging in research. Lastly, monkeys that consistently participated and performed well on both tasks showed significantly higher Openness and lower Assertiveness compared to others, mirroring relationships found between personality, participation, and performance among all participants. Participation and performance during training was clearly biased toward individuals with particular personalities (i.e. high Openness, low Assertiveness). Results are discussed in light of the need for careful interpretation of comparative data on animal cognition and the need for researchers to take personality selection bias more seriously.

  Title Social learning in juvenile lemon sharks, Negaprion brevirostris Type Journal Article
  Year 2013 Publication (up) Abbreviated Journal Animal Cognition  
  Volume 16 Issue 1 Pages 55-64  
  Keywords Local and stimulus enhancement; Group living; Social facilitation; Social information use; Elasmobranchs  
  Abstract Social learning is taxonomically widespread and can provide distinct behavioural advantages, such as in finding food or avoiding predators more efficiently. Although extensively studied in bony fishes, no such empirical evidence exists for cartilaginous fishes. Our aim in this study was to experimentally investigate the social learning capabilities of juvenile lemon sharks, Negaprion brevirostris. We designed a novel food task, where sharks were required to enter a start zone and subsequently make physical contact with a target in order to receive a food reward. Naive sharks were then able to interact with and observe (a) pre-trained sharks, that is, ‘demonstrators’, or (b) sharks with no previous experience, that is, ‘sham demonstrators’. On completion, observer sharks were then isolated and tested individually in a similar task. During the exposure phase observers paired with ‘demonstrator’ sharks performed a greater number of task-related behaviours and made significantly more transitions from the start zone to the target, than observers paired with ‘sham demonstrators’. When tested in isolation, observers previously paired with ‘demonstrator’ sharks completed a greater number of trials and made contact with the target significantly more often than observers previously paired with ‘sham demonstrators’. Such experience also tended to result in faster overall task performance. These results indicate that juvenile lemon sharks, like numerous other animals, are capable of using socially derived information to learn about novel features in their environment. The results likely have important implications for behavioural processes, ecotourism and fisheries.

  Title Antiaggressive activity of central oxytocin in male rats Type Journal Article
  Year 2013 Publication (up) Abbreviated Journal Psychopharmacology  
  Volume 229 Issue 4 Pages 639-651  
  Keywords Oxytocin; Offensive aggression; Social exploration; Individual variability  
  Abstract Rationale A substantial body of research suggests that the

neuropeptide oxytocin promotes social affiliative behaviors

in a wide range of animals including humans. However, its

antiaggressive action has not been unequivocally demonstrated

in male laboratory rodents.

Objective Our primary goal was to examine the putative

serenic effect of oxytocin in a feral strain (wild type

Groningen, WTG) of rats that generally show a much

broader variation and higher levels of intermale aggression

than commonly used laboratory strains of rats.

Methods Resident animals were intracerebroventricularly

(icv) administered with different doses of synthetic oxytocin

and oxytocin receptor antagonist, alone and in combination,

in order to manipulate brain oxytocin functioning and to

assess their behavioral response to an intruder.

Results Our data clearly demonstrate that acute icv administered

oxytocin produces dose-dependent and receptorselective

changes in social behavior, reducing aggression

and potentiating social exploration. These antiaggressive

effects are stronger in the more offensive rats. On the other

hand, administration of an oxytocin receptor antagonist

tends to increase (nonsignificantly) aggression only in

low–medium aggressive animals.

Conclusions These results suggest that transiently enhancing

brain oxytocin function has potent antiaggressive effects,

whereas its attenuation tends to enhance aggressiveness. In

addition, a possible inverse relationship between trait aggression

and endogenous oxytocinergic signaling is revealed.

Overall, this study emphasizes the importance of brain

oxytocinergic signaling for regulating intermale offensive aggression.

This study supports the suggestion that oxytocin

receptor agonists could clinically be useful for curbing heightened

aggression seen in a range of neuropsychiatric disorders

like antisocial personality disorder, autism, and addiction.

  Title A juvenile mouse pheromone inhibits sexual behaviour through the vomeronasal system Type Journal Article
  Year 2013 Publication (up) Abbreviated Journal Nature  
  Volume 502 Issue 7471 Pages 368-371  
  Keywords Pheromone Olfactory receptors  
  Abstract Animals display a repertoire of different social behaviours. Appropriate behavioural responses depend on sensory input received during social interactions. In mice, social behaviour is driven by pheromones, chemical signals that encode information related to age, sex and physiological state1. However, although mice show different social behaviours towards adults, juveniles and neonates, sensory cues that enable specific recognition of juvenile mice are unknown. Here we describe a juvenile pheromone produced by young mice before puberty, termed exocrine-gland secreting peptide 22 (ESP22). ESP22 is secreted from the lacrimal gland and released into tears of 2- to 3-week-old mice. Upon detection, ESP22 activates high-affinity sensory neurons in the vomeronasal organ, and downstream limbic neurons in the medial amygdala. Recombinant ESP22, painted on mice, exerts a powerful inhibitory effect on adult male mating behaviour, which is abolished in knockout mice lacking TRPC2, a key signalling component of the vomeronasal organ2, 3. Furthermore, knockout of TRPC2 or loss of ESP22 production results in increased sexual behaviour of adult males towards juveniles, and sexual responses towards ESP22-deficient juveniles are suppressed by ESP22 painting. Thus, we describe a pheromone of sexually immature mice that controls an innate social behaviour, a response pathway through the accessory olfactory system and a new role for vomeronasal organ signalling in inhibiting sexual behaviour towards young. These findings provide a molecular framework for understanding how a sensory system can regulate behaviour.

  Title Characterization of long-term memory, resistance to extinction, and influence of temperament during two instrumental tasks in horses Type Journal Article
  Year 2013 Publication (up) Abbreviated Journal Animal Cognition  
  Volume 16 Issue 6 Pages 1001-1006  
  Keywords Personality; Learning; Individuality; Fearfulness; Equid; Cognitive flexibility  
  Abstract The present study investigated the influence of temperament on long-term recall and extinction of 2 instrumental tasks in 26 horses. In the first task (backward task), horses learned to walk backward, using commands given by an experimenter, in order to obtain a food reward. In the second task (active avoidance task), horses had to cross an obstacle after a bell rang in order to avoid emission of an air puff. Twenty-two months after acquisition, horses exhibited perfect recall performance in both tasks. Accordingly, no influence of temperament on recall performance could be observed for either task. In contrast, in the absence of positive or negative outcomes, the horses’ ability to extinguish their response to either task was highly variable. Resistance to extinction was related to some indicators of temperament: The most fearful horses tended to be the most resistant to extinction in the backward task, while the least sensitive horses tended to be the most resistant to extinction in the active avoidance task. These findings reveal extensive long-term memory abilities in horses and suggest an influence of temperament on learning processes other than acquisition.

  Title The mind of the horse, An Introduction to Equine Cognition Type Book Whole
  Year 2013 Publication (up) Abbreviated Journal  
  Volume Issue Pages  
  Keywords  
  Abstract Horses were first domesticated about 6,000 years ago on the vast Eurasian steppe extending from Mongolia to the Carpathian Mountains. Yet only in the last two decades have scientists begun to explore the specific mental capacities of these animals. Responding to a surge of interest in fields from ethology to comparative psychology and evolutionary biology, Michel-Antoine Leblanc presents an encyclopedic synthesis of scientific knowledge about equine behavior and cognition. The Mind of the Horse provides experts and enthusiasts alike with an up-to-date understanding of how horses perceive, think about, and adapt to their physical and social worlds.

Much of what we know—or think we know—about “the intelligence of the horse” derives from fragmentary reports and anecdotal evidence. Putting this accumulated wisdom to the test, Leblanc introduces readers to rigorous experimental investigations into how horses make sense of their world under varying conditions. He describes the anatomical and neurophysiological characteristics of the horse’s brain, and offers an evolutionary perspective by comparing these features with those of other species. A horseman himself, Leblanc also considers the opinions of renowned riding masters, as well as controversies surrounding the extraordinary powers of the horse’s mind that have stirred in equestrian and scientific circles.

Although scientists understand more today about how horses think than at any time in our species’ long acquaintance with these animals, much remains in the dark. The Mind of the Horse brings together the current state of equine research and will likely stimulate surprising new discoveries.

  Title Gender and Equestrian Sport Type Book Whole
  Year 2013 Publication (up) Abbreviated Journal  
  Volume Issue Pages  
  Keywords British Equestrian Sport Canadian Show Jumping Cojones and Rejones Comparative Analysis Equestrian World through a Gender Lens Equestrianism during the 20th Century Fluid Masculinities on Brazilian Dressage Gender Studies and Equestrian Sport Horseracing and Gender in the United Kingdom Juvenile Equine Fiction for Girls Men and Horse Riding Spanish Mounted Bullfight Sport and Culture Swedish Equestrian Sports Women Riding Rodeo in Southern Brazil Women in Equestrian Polo  
  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.
