| Title | Chimpanzees do not take into account what others can hear in a competitive situation | Type | Journal Article | ||

Abstract  |
Chimpanzees (Pan troglodytes) know what others can and cannot see in a competitive situation. Does this reflect a general understanding the perceptions of others` In a study by Hare et al. (2000) pairs of chimpanzees competed over two pieces of food. Subordinate individuals preferred to approach food that was behind a barrier that the dominant could not see, suggesting that chimpanzees can take the visual perspective of others. We extended this paradigm to the auditory modality to investigate whether chimpanzees are sensitive to whether a competitor can hear food rewards being hidden. Results suggested that the chimpanzees did not take what the competitor had heard into account, despite being able to locate the hiding place themselves by the noise. | ||||

| Abstract |
Canada has a variety of educational offerings in equine management at the diploma and certificate level offered by universities and colleges, as well as by industry supported centres. However, it was not until 2007 that the first degree-based program in equine science was launched. Offered by the University of Guelph, the Bachelor of Bio- Resource Management – Equine Management program is designed for students who do not intend to pursue post-graduate studies and are strongly focused on securing employment that makes use of the knowledge acquired in their bachelor's degree. The courses in the BSc-program include basic natural sciences as well as equine-specific courses with a focus on management of equine related businesses and events. Diploma and certificate programs usually include only specifically equine-related courses e.g. in anatomy and physiology, health, business, facility management and nutrition. All diploma and certificate programs, and to a slightly lesser extent the BSc program, have a strong focus on applied learning with the intent to provide highly trained workers for the industry. Unique in Canada are the entirely online-taught Diploma in Equine Studies, the Certificate in Equine Business Management and the Equine Science Certificate offered by Equine Guelph and the University of Guelph"s continuing education. Students of these programs have access to a virtual classroom via the internet, and therefore access to instructors and guest speakers from the industry throughout the course. The Canadian certificate programs typically take one year (two semesters), the diploma programs two years (four semesters), while the BSc program takes four years (eight semesters). The BSc program requires approximately 2000 hours of in-class time plus roughly twice the amount spent on assignments and studying, totalling to an overall workload of roughly 6000 hours. Most programs require the completion of Grade 12 or equivalent for admission, and in all programs a background and experience with horses is not required for admission, however it is usually deemed beneficial. Career options for BSc-graduates include barn management, riding instructor or coach, professional rider, judge, steward, course designer, equine-assisted therapy, veterinary assistant, event manager, nutrition consultant, retail sales in tack and equipment, equine sales and marketing, agriculture extension services, college lecturer, consultant and technical advisor, and media relations. Career options for the diploma and certificate program graduates generally include similar areas, with a focus on hands-on work and direct interaction with horses such as employment as grooms, trainers and barn managers. | ||||

| Title | Precise auditory-vocal mirroring in neurons for learned vocal communication | Type | Journal Article | ||
| Year | 2008 | Publication | Nature | Abbreviated Journal | Nature |
| Volume | 451 | Issue | 7176 | Pages | 305-310 |
| Keywords | |||||
| Abstract |
Brain mechanisms for communication must establish a correspondence between sensory and motor codes used to represent the signal. One idea is that this correspondence is established at the level of single neurons that are active when the individual performs a particular gesture or observes a similar gesture performed by another individual. Although neurons that display a precise auditory–vocal correspondence could facilitate vocal communication, they have yet to be identified. Here we report that a certain class of neurons in the swamp sparrow forebrain displays a precise auditory–vocal correspondence. We show that these neurons respond in a temporally precise fashion to auditory presentation of certain note sequences in this songbird’s repertoire and to similar note sequences in other birds’ songs. These neurons display nearly identical patterns of activity when the bird sings the same sequence, and disrupting auditory feedback does not alter this singing-related activity, indicating it is motor in nature. Furthermore, these neurons innervate striatal structures important for song learning, raising the possibility that singing-related activity in these cells is compared to auditory feedback to guide vocal learning. |

| Title | Revisiting the definition of animal tool use | Type | Journal Article | ||
| Year | 2008 | Publication | Animal Behaviour | Abbreviated Journal | Anim. Behav. |
| Volume | 75 | Issue | 4 | Pages | 1199-1208 |
| Keywords | cognition; tool use | ||||
| Abstract |
Benjamin Beck's definition of tool use has served the field of animal cognition well for over 25 years (Beck 1980, Animal Tool Behavior: the Use and Manufacture of Tools, New York, Garland STPM). This article proposes a new, more explanatory definition that accounts for tool use in terms of two complementary subcategories of behaviours: behaviours aimed at altering a target object by mechanical means and behaviours that mediate the flow of information between the tool user and the environment or other organisms in the environment. The conceptual foundation and implications of the new definition are contrasted with those of existing definitions, particularly Beck's. The new definition is informally evaluated with respect to a set of scenarios that highlights differences from Beck's definition as well as those of others in the literature. | ||||

| Abstract |
Bei einer für die Schweiz repräsentativ und zufällig ausgewählten Stichprobe von 2912 Pferden und Ponys wurden mittels Fragebogen Daten zum aktuellen Gesundheitszustand und zum Auftreten von Erkrankungen und Verletzungen während der vergangenen 12 Monate erfasst. 718 Pferde (24.7%) wurden im Erfassungszeitraum wegen 897 gesundheitlichen Problemen einem Tierarzt vorgestellt. Orthopädische und traumatische Fälle machten den grössten Anteil aus (41.5%), gefolgt von Erkrankungen des Gastrointestinal- (27.1%) und des Respirationstrakts (14.0%). Die Hälfte der Lahmheiten entstand als unmittelbare Folge einer Verletzung. Die Verletzungen waren assoziiert mit Weidegang/Auslauf (38.1%), Schläge/Bissen durch Artgenossen (21.6%), Stall (7.8%), Gelände (13.4%), Training (3.5%), Wettkampf (3.5%), Transport (3.0%) oder mit anderen Umständen (9.1%). In 26.5% der Kolikfälle wurde im Monat vor der Erkrankung Futterumstellung vorgenommen. Bei den Atmungserkrankungen wurde in 13.8% die gleiche Krankheit auch bei anderen Pferden im Stall diagnostiziert. Bei 8.1% aller Fälle erfolgte eine Operation, 6.7% waren mit einem mehrtägigem Klinikaufenthalt verbunden. Bei 25.6% aller tiermedizinisch diagnostizierten Fälle wurden ergänzend oder ausschliesslich komplementärmedizinische Therapiemethoden eingesetzt. | ||||

| Title | Sex-specific asymmetries in communication sound perception are not related to hand preference in an early primate | Type | Journal Article | ||

| Volume | 6 | Issue | 1 | Pages | 3 |

| Abstract |
BACKGROUND:Left hemispheric dominance of language processing and handedness, previously thought to be unique to humans, is currently under debate. To gain an insight into the origin of lateralization in primates, we have studied gray mouse lemurs, suggested to represent the most ancestral primate condition. We explored potential functional asymmetries on the behavioral level by applying a combined handedness and auditory perception task. For testing handedness, we used a forced food-grasping task. For testing auditory perception, we adapted the head turn paradigm, originally established for exploring hemispheric specializations in conspecific sound processing in Old World monkeys, and exposed 38 subjects to control sounds and conspecific communication sounds of positive and negative emotional valence.RESULTS:The tested mouse lemur population did not show an asymmetry in hand preference or in orientation towards conspecific communication sounds. However, males, but not females, exhibited a significant right ear-left hemisphere bias when exposed to conspecific communication sounds of negative emotional valence. Orientation asymmetries were not related to hand preference.CONCLUSION:Our results provide the first evidence for sex-specific asymmetries for conspecific communication sound perception in non-human primates. Furthermore, they suggest that hemispheric dominance for communication sound processing evolved before handedness and independently from each other. | ||||

| Title | The emergence of leaders and followers in foraging pairs when the qualities of individuals differ | Type | Journal Article | ||
| Year | 2008 | Publication | BMC Evolutionary Biology | Abbreviated Journal | BMC Evol Biol |

| Abstract |
BACKGROUND: Foraging in groups offers animals a number of advantages, such as increasing their likelihood of finding food or detecting and avoiding predators. In order for a group to remain together, there has to be some degree of coordination of behaviour and movement between its members (which may in some cases be initiated by a decision-making leader, and in other cases may emerge as an underlying property of the group). For example, behavioural synchronisation is a phenomenon where animals within a group initiate and then continue to conduct identical behaviours, and has been characterised for a wide range of species. We examine how a pair of animals should behave using a state-dependent approach, and ask what conditions are likely to lead to behavioural synchronisation occurring, and whether one of the individuals is more likely to act as a leader. RESULTS: The model we describe considers how the energetic gain, metabolic requirements and predation risks faced by the individuals affect measures of their energetic state and behaviour (such as the degree of behavioural synchronisation seen within the pair, and the value to an individual of knowing the energetic state of its colleague). We explore how predictable changes in these measures are in response to changes in physiological requirements and predation risk. We also consider how these measures should change when the members of the pair are not identical in their metabolic requirements or their susceptibility to predation. We find that many of the changes seen in these measures are complex, especially when asymmetries exist between the members of the pair. CONCLUSION: Analyses are presented that demonstrate that, although these general patterns are robust, care needs to be taken when considering the effects of individual differences, as the relationship between individual differences and the resulting qualitative changes in behaviour may be complex. We discuss how these results are related to experimental observations, and how the model and its predictions could be extended. | ||||

| Title | Systematic Review of the Empirical Evidence of Study Publication Bias and Outcome Reporting Bias | Type | Journal Article | ||

| Abstract |
Background The increased use of meta-analysis in systematic reviews of healthcare interventions has highlighted several types of bias that can arise during the completion of a randomised controlled trial. Study publication bias has been recognised as a potential threat to the validity of meta-analysis and can make the readily available evidence unreliable for decision making. Until recently, outcome reporting bias has received less attention. Methodology/Principal Findings We review and summarise the evidence from a series of cohort studies that have assessed study publication bias and outcome reporting bias in randomised controlled trials. Sixteen studies were eligible of which only two followed the cohort all the way through from protocol approval to information regarding publication of outcomes. Eleven of the studies investigated study publication bias and five investigated outcome reporting bias. Three studies have found that statistically significant outcomes had a higher odds of being fully reported compared to non-significant outcomes (range of odds ratios: 2.2 to 4.7). In comparing trial publications to protocols, we found that 40-62% of studies had at least one primary outcome that was changed, introduced, or omitted. We decided not to undertake meta-analysis due to the differences between studies. Conclusions Recent work provides direct empirical evidence for the existence of study publication bias and outcome reporting bias. There is strong evidence of an association between significant results and publication; studies that report positive or significant results are more likely to be published and outcomes that are statistically significant have higher odds of being fully reported. Publications have been found to be inconsistent with their protocols. Researchers need to be aware of the problems of both types of bias and efforts should be concentrated on improving the reporting of trials. | ||||

| Abstract |
Aus dem Inhalt: * Warum Freispringen? * Die Ausstattung * Der Ablauf * Sehen lernen * Freispringen aufbauen * Fehler korrigieren Kurzbeschreibung In vielen größeren Reitställen wird das Freispringen von den dortigen Ausbildern für die untergestellten Pferde angeboten. Doch auch in Eigenregie und auf kleineren Anlagen – sowohl in der Halle als auch auf dem Reitplatz – lässt sich das Freispringen organisieren und durchführen. Es bringt Abwechslung in den Trainingsalltag von Pferden aller Rassen und Reitweisen und hat auch für Pferde, die unter dem Sattel nicht springen müssen, einen hervorragenden gymnastizierenden Effekt. Für Springpferde gehört das Freispringen zu einem durchdachten Trainingskonzept zwingend dazu – lernen sie hierbei doch, Selbstvertrauen und Routine zu gewinnen und ihre Springtechnik zu verbessern. Voraussetzung ist, dass die Menschen, die das Freispringen durchführen, die Hindernisse sachkundig aufbauen, die Pferde richtig vorbereiten und den Ablauf des Freispringens den Fähigkeiten des jeweiligen Kandidaten entsprechend gestalten. Das notwendige Handwerkszeug hierfür liefert ihnen dieses verständlich geschriebene und mit vielen erläuternden Bildern und Bildabfolgen versehene Buch. Über den Autor Claudia Götz, geboren 1965, ist Diplomjournalistin und arbeitet unter anderem als Sachbuchautorin. Als Matrix-Rhythmus-Therapeutin verfügt sie über umfangreiches Wissen rund um Anatomie und Physiologie der Muskulatur und bildet sich zum Beispiel im Bereich Trainingslehre regelmäßig weiter. Die Berittführerin FN und begeisterte Vielseitigkeits- und Freizeitreiterin lebt in der Nähe von Regensburg. |

| Abstract |
Associative learning theories presume the existence of a general purpose learning process, the structure of which does not mirror the demands of any particular learning problem. In contrast, learning scientists working within an Evolutionary Biology tradition believe that learning processes have been shaped by ecological demands. One potential means of exploring how ecology may have modified properties of acquisition is to use associative learning theory as a framework within which to analyse a particular learning phenomenon. Recent work has used this approach to examine whether socially transmitted predator avoidance can be conceptualised as a classical conditioning process in which a novel predator stimulus acts as a conditioned stimulus (CS) and acquires control over an avoidance response after it has become associated with alarm signals of social companions, the unconditioned stimulus (US). I review here a series of studies examining the effect of CS/US presentation timing on the likelihood of acquisition. Results suggest that socially acquired predator avoidance may be less sensitive to forward relationships than traditional classical conditioning paradigms. I make the case that socially acquired predator avoidance is an exciting novel one-trial learning paradigm that could be studied along side fear conditioning. Comparisons between social and non-social learning of danger at both the behavioural and neural level may yield a better understanding of how ecology might shape properties and mechanisms of learning. | ||||
