  Title From Science to Practice: A Review of Laterality Research on Ungulate Livestock Type Journal Article
  Year 2019 Publication (down) Symmetry Abbreviated Journal Symmetry  
  Volume 11 Issue 9 Pages 1157  
  Keywords hemispheric asymmetries; farm animals; emotional processing; animal cognition; development; human-animal interactions; animal welfare  
  Abstract In functional laterality research, most ungulate livestock species have until recently been mainly overlooked. However, there are many scientific and practical benefits of studying laterality in ungulate livestock. As social, precocial and domestic species, they may offer insight into the mechanisms involved in the ontogeny and phylogeny of functional laterality and help to better understand the role of laterality in animal welfare. Until now, most studies on ungulate livestock have focused on motor laterality, but interest in other lateralized functions, e.g., cognition and emotions, is growing. Increasingly more studies are also focused on associations with age, sex, personality, health, stress, production and performance. Although the full potential of research on laterality in ungulate livestock is not yet exploited, findings have already shed new light on central issues in cognitive and emotional processing and laid the basis for potentially useful applications in future practice, e.g., stress reduction during human-animal interactions and improved assessments of health, production and welfare. Future research would benefit from further integration of basic laterality methodology (e.g., testing for individual preferences) and applied ethological approaches (e.g., established emotionality tests), which would not only improve our understanding of functional laterality but also benefit the assessment of animal welfare.

  Title Asymmetry of Motor Behavior and Sensory Perception: Which Comes First? Type Journal Article
  Year 2020 Publication (down) Symmetrie Abbreviated Journal Symmetrie  
  Volume 12 Issue 5 Pages 690  
  Keywords development; motor asymmetry; visual lateralization; human fetus; chick embryo; sensory-motor interaction  
  Abstract By examining the development of lateralization in the sensory and motor systems of the human fetus and chick embryo, this paper debates which lateralized functions develop first and what interactions may occur between the different sensory and motor systems during development. It also discusses some known influences of inputs from the environment on the development of lateralization, particularly the effects of light exposure on the development of visual and motor lateralization in chicks. The effects of light on the human fetus are related in this context. Using the chick embryo as a model to elucidate the genetic and environmental factors involved in development of lateralization, some understanding has been gained about how these lateralized functions emerge. At the same time, the value of carrying out much more research on the development of the various types of lateralization has become apparent.

  Title Neue Reitsportmotive jenseits des klassischen Turniersports Type Journal Article
  Year 2011 Publication (down) Sportwissenschaft Abbreviated Journal  
  Volume 41 Issue 1 Pages 34-43  
  Keywords  
  Abstract Während die traditionellen Pferdesportdisziplinen Dressur- und Springreiten Mitglieder verlieren, haben sich weitere Pferdesportarten in Deutschland etabliert und erfreuen sich wachsender Beliebtheit. Die vorliegende Arbeit beschäftigt sich mit den Hintergründen dieser Entwicklung. In einer empirischen Untersuchung wurden 1814 Reiter zu ihren Reitmotiven befragt. Mit Hilfe von Hauptkomponenten- und Clusteranalyse wurde eine Typologie gebildet, die ein differenziertes Bild der Motive verschiedener Reitergruppen ermöglicht. Während die leistungsorientierten Reiter eher in klassischen Reitsportdisziplinen vertreten sind, dominieren in moderneren Reitsportdisziplinen vor allem Genussmotive. Insgesamt entwickelt sich der Trend im Reitsport deutlich vom Drill in der Reitbahn hin zu mehr Entspannung, Erholung und Selbstverwirklichung. Der Wunsch, in der Freizeit Leistung zu bringen, sich mit anderen zu messen und Erfolg zu haben, ist nur noch für einen kleineren Teil der Pferdesportler bedeutsam. Aus der Verteilung der Motive ergeben sich neue Herausforderungen für den organisierten Reitsport, um den Spagat zwischen den Anforderungen der leistungsorientierten Sportreiter und den Erholungssuchenden zu meistern.

  Title Cross-modal perception of human emotion in domestic horses (Equus caballus) Type Journal Article
  Year 2018 Publication (down) Scientific Reports Abbreviated Journal  
  Volume 8 Issue 1 Pages 8660  
  Keywords  
  Abstract Humans have domesticated many kinds of animals in their history. Dogs and horses have particularly close relationships with humans as cooperative partners. However, fewer scientific studies have been conducted on cognition in horses compared to dogs. Studies have shown that horses cross-modally distinguish human facial expressions and recognize familiar people, which suggests that they also cross-modally distinguish human emotions. In the present study, we used the expectancy violation method to investigate whether horses cross-modally perceive human emotions. Horses were shown a picture of a human facial expression on a screen, and they then heard a human voice from the speaker before the screen. The emotional values of the visual and auditory stimuli were the same in the congruent condition and different in the incongruent condition. Horses looked at the speaker significantly longer in the incongruent condition than in the congruent condition when they heard their caretaker's voices but not when they heard the stranger voice. In addition, they responded significantly more quickly to the voice in the incongruent condition than in the congruent one. To the best of our knowledge, this is the first study to show that horses cross-modally recognized the emotional states of their caretakers and strangers.

  Title Horses associate individual human voices with the valence of past interactions: a behavioural and electrophysiological study Type Journal Article
  Year 2019 Publication (down) Scientific Reports Abbreviated Journal  
  Volume 9 Issue 1 Pages 11568  
  Keywords  
  Abstract Brain lateralization is a phenomenon widely reported in the animal kingdom and sensory laterality has been shown to be an indicator of the appraisal of the stimulus valence by an individual. This can prove a useful tool to investigate how animals perceive intra- or hetero-specific signals. The human-animal relationship provides an interesting framework for testing the impact of the valence of interactions on emotional memories. In the present study, we tested whether horses could associate individual human voices with past positive or negative experiences. Both behavioural and electroencephalographic measures allowed examining laterality patterns in addition to the behavioural reactions. The results show that horses reacted to voices associated with past positive experiences with increased attention/arousal (gamma oscillations in the right hemisphere) and indicators of a positive emotional state (left hemisphere activation and ears held forward), and to those associated with past negative experiences with negative affective states (right hemisphere activation and ears held backwards). The responses were further influenced by the animals' management conditions (e.g. box or pasture). Overall, these results, associating brain and behaviour analysis, clearly demonstrate that horses' representation of human voices is modulated by the valence of prior horse-human interactions.

  Title Female horses spontaneously identify a photograph of their keeper, last seen six months previously Type Journal Article
  Year 2020 Publication (down) Scientific Reports Abbreviated Journal  
  Volume 10 Issue 1 Pages 6302  
  Keywords  
  Abstract Horses are capable of identifying individual conspecifics based on olfactory, auditory or visual cues. However, this raises the questions of their ability to recognize human beings and on the basis of what cues. This study investigated whether horses could differentiate between a familiar and unfamiliar human from photographs of faces. Eleven horses were trained on a discrimination task using a computer-controlled screen, on which two photographs were presented simultaneously (32 trials/session): touching one was rewarded (S+) and the other not (S-). In the training phase, the S+ faces were of four unfamiliar people which gradually became familiar over the trials. The S- faces were novel for each trial. After the training phase, the faces of the horses' keepers were presented opposite novel faces to test whether the horses could identify the former spontaneously. A reward was given whichever face was touched to avoid any possible learning effect. Horses touched the faces of keepers significantly more than chance, whether it was their current keeper or one they had not seen for six months (t = 3.65; p < 0.004 and t = 6.24; p < 0.0001). Overall, these results show that horses have advanced human face-recognition abilities and a long-term memory of those human faces.

  Title Lateralization influences contest behaviour in domestic pigs Type Journal Article
  Year 2018 Publication (down) Scientific Reports Abbreviated Journal  
  Volume 8 Issue 1 Pages 12116  
  Keywords  
  Abstract Cerebral lateralization, i.e. hemispheric asymmetries in structure and function, relates in many species to a preference to attack from their left. Lateralization increases cognitive capacity, enabling the simultaneous processing of multiple sources of information. Therefore, lateralization may constitute a component of fighting ability (Resource Holding Potential), and/or influence the efficiency of information-gathering during a contest. We hypothesized that lateralization will affect contest outcome and duration, with an advantage for more strongly lateralized individuals. In 52 dyadic contests between weight-matched pigs (Sus scrofa; n = 104; 10 wk age), the direction of orientation towards the opponent was scan sampled every 10 s. Laterality indexes (LI) were calculated for the direction and strength of lateralization. Up to 12.5% of the individuals showed significant lateralization towards either the right or left but lateralization was absent at the population level. In line with our hypothesis, animals showing strong lateralization (irrespective of direction) had a shorter contest duration than animals showing weak lateralization. Winners did not differ from losers in their strength or direction of lateralization. Overall the results suggest that cerebral lateralization may aid in conflict resolution, but does not directly contribute to fighting ability, and will be of value in the study of animal contests.

  Title Empathy and Pro-Social Behavior in Rats Type Journal Article
  Year 2011 Publication (down) Science Abbreviated Journal Science  
  Volume 334 Issue 6061 Pages 1427-1430  
  Keywords  
  Abstract Whereas human pro-social behavior is often driven by empathic concern for another, it is unclear whether nonprimate mammals experience a similar motivational state. To test for empathically motivated pro-social behavior in rodents, we placed a free rat in an arena with a cagemate trapped in a restrainer. After several sessions, the free rat learned to intentionally and quickly open the restrainer and free the cagemate. Rats did not open empty or object-containing restrainers. They freed cagemates even when social contact was prevented. When liberating a cagemate was pitted against chocolate contained within a second restrainer, rats opened both restrainers and typically shared the chocolate. Thus, rats behave pro-socially in response to a conspecific&#65533;s distress, providing strong evidence for biological roots of empathically motivated helping behavior.
