Perceptual Lateralization Of Vocal Stimuli In Goats, Luigi Baciadonna, Christian Nawroth, Elodie F. Briefer, Alan G. Mcelligott Jul 2019

Perceptual Lateralization Of Vocal Stimuli In Goats, Luigi Baciadonna, Christian Nawroth, Elodie F. Briefer, Alan G. Mcelligott

Christian Nawroth, PhD

Functional asymmetries, for example, the preferential involvement of 1 brain hemisphere to process stimuli, may increase brain efficiency and the capacity to carry out tasks simultaneously. We investigated which hemisphere was primarily involved in processing acoustic stimuli in goats using a head-orienting paradigm. Three playbacks using goat vocalizations recorded in different contexts: food anticipation (positive), isolation (negative), food frustration (negative), as well as 1 playback involving dog barks (negative) were presented on the left and right sides of the test subjects simultaneously. The head-orienting response (left or right) and latency to resume feeding were recorded. The direction of the head-orienting …


Farm Animals Are Not Humans In Sheep Clothing, Lorenz Gygax, Christian Nawroth Jul 2019

Farm Animals Are Not Humans In Sheep Clothing, Lorenz Gygax, Christian Nawroth

Christian Nawroth, PhD

Research on the mental lives of farm animals is crucial to assess not only their physical but also their psychological wellbeing. Their current housing and handling practices are highly unlikely to meet their cognitive needs and demands, but our knowledge of their mental capacities is still limited. Although folk wisdom often refers to farm animals as dull and inflexible, recent studies show they have a rich interpretation of their environment and can solve complex problems. Yet an uncritical and anthropomorphic assessment of farm animal cognition and behaviour may lead to the attribution of an exaggerated amount of cognitive flexibility. Contrary …


Looking On The Bright Side Of Livestock Emotions—The Potential Of Their Transmission To Promote Positive Welfare, Luigi Baciadonna, Sandra Duepjan, Elodie Briefer, Mónica Padilla De La Torre, Christian Nawroth Apr 2019

Looking On The Bright Side Of Livestock Emotions—The Potential Of Their Transmission To Promote Positive Welfare, Luigi Baciadonna, Sandra Duepjan, Elodie Briefer, Mónica Padilla De La Torre, Christian Nawroth

Christian Nawroth, PhD

Emotions can be defined as an individual’s affective reaction to an external and/or internal event that, in turn, generates a simultaneous cascade of behavioral, physiological, and cognitive changes. Those changes that can be perceived by conspecifics have the potential to also affect other’s emotional states, a process labeled as “emotional contagion.” Especially in the case of gregarious species, such as livestock, emotional contagion can have an impact on the whole group by, for instance, improving group coordination and strengthening social bonds. We noticed that the current trend of research on emotions in livestock, i.e., investigating affective states as a tool …


Human Demonstration Does Not Facilitate The Performance Of Horses (Equus Caballus) In A Spatial Problem-Solving Task, Joan-Bryce Burla, Janina Siegwart, Christian Nawroth Apr 2019

Human Demonstration Does Not Facilitate The Performance Of Horses (Equus Caballus) In A Spatial Problem-Solving Task, Joan-Bryce Burla, Janina Siegwart, Christian Nawroth

Christian Nawroth, PhD

Horses’ ability to adapt to new environments and to acquire new information plays an important role in handling and training. Social learning in particular would be very adaptive for horses as it enables them to flexibly adjust to new environments. In the context of horse handling, social learning from humans has been rarely investigated but could help to facilitate management practices. We assessed the impact of human demonstration on the spatial problem-solving abilities of horses during a detour task. In this task, a bucket with a food reward was placed behind a double-detour barrier and 16 horses were allocated to …


Goats Prefer Positive Human Emotional Facial Expressions, Christian Nawroth, Natalia Albuquerque, Carine Savalli, Marie-Sophie Single, Alan G. Mcelligott Apr 2019

Goats Prefer Positive Human Emotional Facial Expressions, Christian Nawroth, Natalia Albuquerque, Carine Savalli, Marie-Sophie Single, Alan G. Mcelligott

Christian Nawroth, PhD

Domestication has shaped the physiology and the behaviour of animals to better adapt to human environments. Therefore, human facial expressions may be highly informative for animals domesticated for working closely with people, such as dogs and horses. However, it is not known whether other animals, and particularly those domesticated primarily for production, such as goats, are capable of perceiving human emotional cues. In this study, we investigated whether goats can distinguish human facial expressions when simultaneously shown two images of an unfamiliar human with different emotional valences (positive/ happy or negative/angry). Both images were vertically attached to a wall on …


Human-Directed Behaviour In Goats Is Not Affected By Short-Term Positive Handling, Jan Langbein, Annika Krause, Christian Nawroth Apr 2019

Human-Directed Behaviour In Goats Is Not Affected By Short-Term Positive Handling, Jan Langbein, Annika Krause, Christian Nawroth

Christian Nawroth, PhD

In addition to domestication, interactions with humans or task-specific training during ontogeny have been proposed to play a key role in explaining differences in human–animal communication across species. In livestock, even short-term positive interactions with caretakers or other reference persons can influence human–animal interaction at different levels and over different periods of time. In this study, we investigated human-directed behaviour in the ‘unsolvable task’ paradigm in two groups of domestic goats (Capra aegagrus hircus). One group was positively handled and habituated to a plastic box by the experimenter to retrieve a food reward, while the other group only received standard …


Farm Animal Cognition—Linking Behavior, Welfare And Ethics, Christian Nawroth, Jan Langbein, Marjorie Coulon, Vivian Gabor, Susan Oesterwind, Judith Benz-Schwarzburg, Eberhard Von Borell Apr 2019

Farm Animal Cognition—Linking Behavior, Welfare And Ethics, Christian Nawroth, Jan Langbein, Marjorie Coulon, Vivian Gabor, Susan Oesterwind, Judith Benz-Schwarzburg, Eberhard Von Borell

Christian Nawroth, PhD

Farm animal welfare is a major concern for society and food production. To more accurately evaluate animal farming in general and to avoid exposing farm animals to poor welfare situations, it is necessary to understand not only their behavioral but also their cognitive needs and capacities. Thus, general knowledge of how farm animals perceive and interact with their environment is of major importance for a range of stakeholders, from citizens to politicians to cognitive ethologists to philosophers. This review aims to outline the current state of farm animal cognition research and focuses on ungulate livestock species, such as cattle, horses, …
