| Title | Position of the head is not associated with changes in horse vision | Type | Journal Article | ||
| Year | 2008 | Publication | Equine Veterinary Journal | Abbreviated Journal | |

| Abstract | It has become accepted that the horse cannot see directly in front when the nose is lowered and must therefore rely on the rider. We tested the hypothesis that this conclusion would be correct only if the horse did not adjust the eyeball horizontal axis to changes of the head position. The results of the present study suggest that it is unlikely that horses have limited vision in relation to their head position when driven by the rider, and that the horse maintains the optimal horizontal eyeball position regardless of head position relative to the ground. | ||||

| 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. |

| Title | Oxytocin Shapes the Neural Circuitry of Trust and Trust Adaptation in Humans | Type | Abstract | ||

| Abstract | Trust and betrayal of trust are ubiquitous in human societies. Recent behavioral evidence shows that the neuropeptide oxytocin increases trust among humans, thus offering a unique chance of gaining a deeper understanding of the neural mechanisms underlying trust and the adaptation to breach of trust. We examined the neural circuitry of trusting behavior by combining the intranasal, double-blind, administration of oxytocin with fMRI. We find that subjects in the oxytocin group show no change in their trusting behavior after they learned that their trust had been breached several times while subjects receiving placebo decrease their trust. This difference in trust adaptation is associated with a specific reduction in activation in the amygdala, the midbrain regions, and the dorsal striatum in subjects receiving oxytocin, suggesting that neural systems mediating fear processing (amygdala and midbrain regions) and behavioral adaptations to feedback information (dorsal striatum) modulate oxytocin's effect on trust. These findings may help to develop deeper insights into mental disorders such as social phobia and autism, which are characterized by persistent fear or avoidance of social interactions. | ||||

| Abstract | Fourteen dogs (7 males and 7 females) were tested for their heart rate (HR) and heart rate variability (HRV) responses in different activities and environmental challenges while their movement was controlled. First, we wanted to compare the dogs? cardiac responses in different body positions (lying, sitting and standing) and during slow walking to reveal their possible influence on HR and HRV. Second, we tested the HR response during an attentive state when the dog was gazing at its favourite toy while remaining in a steady body position. Finally we investigated the heart activity during separation from the owner. We also analysed the individual differences and the influence of gender on the heart responses. We found that the HR increased during periods of increased activity (walking) and was lowest during lying, while it did not differ between sitting and standing. At the same time no changes in HRV were found in the case of different body positions and walking. In contrast, HRV significantly increased when dogs oriented towards their favourite toy, and we found a distinct individual characteristic HR change in this situation compared to the similar body position without the toy being shown. Interestingly during separation from the owner the HR did not increase, but when a strange person was petting the dog, a significant increasing effect was seen in the HR. However the HRV increased only when the petting was discontinued. In general, large individual variation was found with regard to the HR and HRV, while gender did not influence the cardiac activity of the dogs.These results show that body position affected HR significantly in dogs. Further it seems that HRV could be a good indicator of the dog's attentive state. Thus in future studies both the physical and cognitive factors should be given more attention when HR or HRV is investigated as a dependent variable. | ||||

| Abstract | Das Droh- und Meideverhalten von 270 Pferden wurde im Fressbereich von 10 Offenlaufställen mit Fressständen und 11 Offenlaufställen mit computergesteuerten Abrufstationen anhand von visuellen kontinuierlichen Direktbeobachtungen erfasst. Diese erfolgten je Betrieb über einen 24-Stunden-Tag, der nach dem Tortenstückverfahren (6x4 Stunden) zusammengesetzt war. Insgesamt wurden 6297 agonistische Verhaltensweisen in, vor und hinter den Fütterungseinrichtungen registriert (Meiden 40,6 %, Verdrängen 12,8 %, Beißen/ Hinterhandschlag/ Angehen 12,7 % und Drohen/ Drohbeißen/ Hinterhanddrohen 33,9 %). In den Futterstationen wurden 22,5 % dieses Verhaltens beobachtet, vor und hinter den Futterstationen 77,5 %. Bei den Betrieben mit Fressständen fanden 31 % der agonistischen Verhaltensweisen in den Ständen statt, bei den Betrieben mit Abruffütterung 21 %. Der Einfl uss des einzelnen Betriebes (innerhalb Fütterungssystem) auf die agonistischen Verhaltensweisen vor und hinter den Fütterungseinrichtungen war signifi kant. Die Auswertung ergab, dass Drohgesten im Wartebereich von Abrufstationen häufi ger auftreten als in dem von Fressständen. Demgegenüber können Pferde in Abrufstationen ungestörter fressen. Insgesamt betrachtet war jedoch die Anzahl an sozionegativen Interaktionen im Bereich der Futtereinrichtungen bei beiden Fütterungssystemen gering. Die agonistischen Verhaltensweisen wurden zusätzlich noch von der Heumenge und dem Konstitutionstyp beeinfl usst. Der Betrieb erwies sich als maßgeblicher Einfl ussfaktor. Als Resümee ergibt sich, dass bei ordnungsgemäßer Gruppenhaltung mit fachgerechtem Management beide Fütterungssysteme für Pferde im Offenlaufstall geeignet sind. [The threatening and avoiding behaviour of 270 horses living in run-out sheds was observed at 10 stables with feeding stalls and at 11 stables with automatic feeding systems for hay and concentrates. Every group of horses was observed on five succeeding days visually and immediately for 6 sessions, each of 4 hours. These 6 slices form together 24 hours, a complete day. Altogether, 6297 agonistic behaviour patterns were registered in front of, inside and behind the feeding stations (avoiding behaviour 40.6 %, edging out of others 12.8 %, Auseinandersetzungen an automatischer Abruffütterung und Fressständen KTBL-Schrift 471 79 biting/rear leg kicking/charging 12.7 % und threatening/biting threats/rear leg kicking threats 33.9 %). 22.5 % of these types of behaviour were recorded in the feeding stations, 77.5 % together in front and behind of these. In the stables with feeding stalls there were 31 % of the observed threatening gestures inside the feeding stations, in the stables with automatic feeders only 21 %. The individual farm showed signifi cant infl uence on the modes of agonistic behaviour in front and behind the feeding facilities. Threatening gestures happen more often in the waiting area of automatic feeders than in that of feeding stalls. On the other hand horses in computer controlled systems will be less disturbed at eating. All together the number of negative interactions in the feeding area at both feeding systems was relatively low. In addition the agonistic behaviour was infl uenced by the quantity of hay and the constitutional typ of the horses. Because of the management of the individual stable exercises the most substantial infl uence on the behaviour of the horses, it can be said, that, correct group keeping with professional management provided, both feeding systems are suitable for horses in run-in sheds.] |

| Abstract | Our decisions are guided by information learnt from our environment. This information may come via personal experiences of reward, but also from the behaviour of social partners1, 2. Social learning is widely held to be distinct from other forms of learning in its mechanism and neural implementation; it is often assumed to compete with simpler mechanisms, such as reward-based associative learning, to drive behaviour3. Recently, neural signals have been observed during social exchange reminiscent of signals seen in studies of associative learning4. Here we demonstrate that social information may be acquired using the same associative processes assumed to underlie reward-based learning. We find that key computational variables for learning in the social and reward domains are processed in a similar fashion, but in parallel neural processing streams. Two neighbouring divisions of the anterior cingulate cortex were central to learning about social and reward-based information, and for determining the extent to which each source of information guides behaviour. When making a decision, however, the information learnt using these parallel streams was combined within ventromedial prefrontal cortex. These findings suggest that human social valuation can be realized by means of the same associative processes previously established for learning other, simpler, features of the environment. | ||||

| Abstract | The tendency of humans to punish perceived free-loaders, even at a cost to themselves, is an evolutionary puzzle: punishers perish, and those who benefit the most are those who have never punished at all. Humans are champions of cooperation. Reciprocity – the idea that, if I help you this time, you'll help me next time1 – is a secret of our success. |

| Abstract | A key aspect of human behaviour is cooperation1, 2, 3, 4, 5, 6, 7. We tend to help others even if costs are involved. We are more likely to help when the costs are small and the benefits for the other person significant. Cooperation leads to a tension between what is best for the individual and what is best for the group. A group does better if everyone cooperates, but each individual is tempted to defect. Recently there has been much interest in exploring the effect of costly punishment on human cooperation8, 9, 10, 11, 12, 13, 14, 15, 16, 17, 18, 19, 20, 21, 22, 23. Costly punishment means paying a cost for another individual to incur a cost. It has been suggested that costly punishment promotes cooperation even in non-repeated games and without any possibility of reputation effects10. But most of our interactions are repeated and reputation is always at stake. Thus, if costly punishment is important in promoting cooperation, it must do so in a repeated setting. We have performed experiments in which, in each round of a repeated game, people choose between cooperation, defection and costly punishment. In control experiments, people could only cooperate or defect. Here we show that the option of costly punishment increases the amount of cooperation but not the average payoff of the group. Furthermore, there is a strong negative correlation between total payoff and use of costly punishment. Those people who gain the highest total payoff tend not to use costly punishment: winners don't punish. This suggests that costly punishment behaviour is maladaptive in cooperation games and might have evolved for other reasons. | ||||

| Volume | 451 | Issue | 7176 | Pages | 305-310 |

| 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. |
