  Title Examining dog–human play: the characteristics, affect, and vocalizations of a unique interspecific interaction Type Journal Article
  Year 2016 Publication Animal Cognition Abbreviated Journal Anim. Cogn.  
  Volume (up) Issue Pages 1-10  
  Keywords  
  Abstract Despite the growing interest in research on the interaction between humans and dogs, only a very few research projects focus on the routines between dogs and their owners. In this study, we investigated one such routine: dog–human play. Dyadic interspecific play is known to be a common interaction between owner and charge, but the details of what counts as play have not been thoroughly researched. Similarly, though people represent that “play” is pleasurable, no study has yet undertaken to determine whether different forms of play are associated with different affective states. Thus, we aimed to generate an inventory of the forms of dyadic play, the vocalizations within play, and to investigate the relationship of affect to elements of play. Via a global citizen science project, we solicited videotapes of dog–human play sessions from dog owners. We coded 187 play bouts via frame-by-frame video playback. We then assessed the relationship between various intra-bout variables and owner affect (positive or neutral) during play (dog affect was overwhelmingly positive). Amount of physical contact (“touch”), level of activity of owner (“movement”), and physical closeness of dog–owner dyad (“proximity”) were highly correlated with positive affect. Owner vocalizations were found to contain different elements in positive- and neutral-affect play. One novel category of play, “tease”, was found. We conclude that not all play is created equal: the experience of play to the owner participant is strongly related to a few identifiable characteristics of the interaction.

  Title Gibt die sensorische Lateralität im Objekttest Aufschluss über das Interieur, den aktuellen Gemütszustand, oder den Trainingszustand der Pferde? Type Conference Article
  Year 2016 Publication 33. FFP-Jahrestagung Abbreviated Journal  
  Volume (up) Issue Pages  
  Keywords  
  Abstract Vor dem obersten Ziel der klassischen Ausbildungsskala für Pferde, die Versammlung, steht das Geraderichten. Ein jedes Pferd ist jedoch von Geburt an asymmetrisch, also schief. Hinter dieser Schiefe verbirgt sich nicht nur die natürliche Schiefe (asymmetrische muskuläre Entwicklung der beiden Körperhälften), die von Geburt an zu beobachten ist, sondern auch die sensorische und motorische Lateralität, also dem ungleichmäßigen Gebrauch der rechten oder linken Sinnesorgane sowie Gliedmaßen, der sich mit der Reifung des Gehirns entwickelt. Alle drei müssen als eigenständige Faktoren, die sich gegenseitig beeinflussen, gesehen werden (Krüger 2014). Um den Weg des Geraderichtens zu erleichtern, sollte in der Ausbildung eines Pferdes nicht nur an der natürlichen Schiefe gearbeitet werden, sondern auch die sensorische und motorische Lateralität beachtet werden um den Prozess des Geraderichtens für das Pferd zu erleichtern. Die sensorische und motorische Lateralität resultiert aus der Aufgabenteilung/Spezialisierung beider Gehirnhälften (Hemisphären) (Rogers 2010). Die rechte Hemisphäre ist dabei für die Verarbeitung von Emotionen (z.B. Angst, Aggression, Freude, Zufriedenheit) sowie für lebenserhaltende Spontanreaktionen zuständig. Die linke Hemisphäre ist für die rationale Verarbeitung von Informationen essentiell (Adolphs et al. 1996, Rogers 2010, Austin und Rogers 2012, De Boyer Des Roches et al. 2008, Demaree et al. 2005, Austin und Rogers 2014). Rückschlüsse auf die Informationsverarbeitung lassen sich über die Beobachtung der verwendeten Sinnesorgane (Ohren und Augen) ziehen, die kontralateral mit den Großhirnhemisphären verbunden sind (Brooks et al. 1999). Es wird vermutet, dass Stress zu einer verstärkten Informationsverarbeitung durch die rechte Großhirnhemisphäre führt (Rogers 2010, Schultheiss et al. 2009). Diese konnte auch in ersten Untersuchungen am Pferd bestätigt werden (unveröffentlichte Daten). Forscher, die den einseitigen Gebrauch von rechten und linken Gliedmaßen (motorische Lateralität) bei Menschen und Tieren untersuchten, zeigten weiterhin Zusammenhänge zur Emotionalität und Reaktivität (McGreevy und Thomson 2006, Rogers 2009, Austin und Rogers 2012, Deesing und Grandin 2014). Die Tendenz zum einseitigen Gebrauch der Gliedmaßen gibt Hinweise auf den „Cognitive Bias“ (= individuelle, kognitive Verzerrung der Wahrnehmung und Verarbeitung von Informationen ins Positive oder Negative) und steht im Zusammenhang mit der persönlichen Neigung auf Stressfaktoren zu reagieren (zusammengefasst von Rogers 2010). Die sensorische Lateralität ändert sich jedoch schneller und situationsgebundener als die motorische Lateralität. Sie wird mittels Objekttests bestimmt, die ebenfalls verwendet werden können um die Reaktivität und Emotionalität zu untersuchen. Für eine objektivere Beurteilung des Interieurs eines Pferdes ist daher zu überlegen, ob die sensorische Lateralität als objektiver Parameter integriert werden kann, welchen Einflüssen diese unterliegt und mit welchen Persönlichkeitsmerkmalen sie korreliert. Wie in der Studie von Farmer et al. (2010) dargestellt werden konnte, zeigten bilateral trainierte Pferde eine weniger stark ausgeprägte Präferenz für die linken Sinnesorgane als traditionell trainierte Pferde in Tests mit Personen (ohne Interaktion). Es stellt sich daher die Frage, ob diese Beobachtung ein Resultat von langjährigem Training ist oder ob es sich bereits nach wenigen Wochen Training einstellt sowie ob solche Entwicklungen auch bei Objekten beobachtet werden können.

Für die erste Untersuchung ergaben sich daher in dieser Studie folgende Fragstellungen: Sind die Ergebnisse eines Objekttests mit Evaluierung der sensorischen Lateralität hinsichtlich der Lateralität wiederholbar? Denn, sollte es möglich sein mittels der sensorische Lateralität auf bestimmte

Persönlichkeitsmerkmale rückschließen zu können, so muss diese genauso stabil und reproduzierbar sein, wie die betreffenden Persönlichkeitsmerkmale. Unterscheiden sich Pferde hinsichtlich ihrer Lateralität in Objekttests, die bereits intensiv gleichmäßig beidseitig trainiert wurden, von Pferden, bei denen weniger Augenmerk auf gleichmäßiges beidseitiges Training gelegt wurde? Kann die Lateralität in Objekttests mit einer definierten gleichmäßigen beidseitigen Trainingsmethode beeinflusst werden? In welche Richtung verschiebt sich gegebenenfalls die Lateralität? Beeinflusst das Alter gegebenenfalls das Ausmaß von Veränderungen, da sich die sensorische Lateralität mit der Reifung des Gehirns entwickelt?

  Title Robust representations of individual faces in chimpanzees (Pan troglodytes) but not monkeys (Macaca mulatta) Type Journal Article
  Year 2016 Publication Animal Cognition Abbreviated Journal Anim. Cogn.  
  Volume (up) Issue Pages 1-9  
  Keywords  
  Abstract Being able to recognize the faces of our friends and family members no matter where we see them represents a substantial challenge for the visual system because the retinal image of a face can be degraded by both changes in the person (age, expression, pose, hairstyle, etc.) and changes in the viewing conditions (direction and degree of illumination). Yet most of us are able to recognize familiar people effortlessly. A popular theory for how face recognition is achieved has argued that the brain stabilizes facial appearance by building average representations that enhance diagnostic features that reliably vary between people while diluting features that vary between instances of the same person. This explains why people find it easier to recognize average images of people, created by averaging multiple images of the same person together, than single instances (i.e. photographs). Although this theory is gathering momentum in the psychological and computer sciences, there is no evidence of whether this mechanism represents a unique specialization for individual recognition in humans. Here we tested two species, chimpanzees (Pan troglodytes) and rhesus monkeys (Macaca mulatta), to determine whether average images of different familiar individuals were easier to discriminate than photographs of familiar individuals. Using a two-alternative forced-choice, match-to-sample procedure, we report a behaviour response profile that suggests chimpanzees encode the faces of conspecifics differently than rhesus monkeys and in a manner similar to humans.

  Title Domestic horses send signals to humans when they face with an unsolvable task Type Journal Article
  Year 2016 Publication Animal Cognition Abbreviated Journal Anim. Cogn.  
  Volume (up) Issue Pages 1-9  
  Keywords  
  Abstract Some domestic animals are thought to be skilled at social communication with humans due to the process of domestication. Horses, being in close relationship with humans, similar to dogs, might be skilled at communication with humans. Previous studies have indicated that they are sensitive to bodily signals and the attentional state of humans; however, there are few studies that investigate communication with humans and responses to the knowledge state of humans. Our first question was whether and how horses send signals to their potentially helpful but ignorant caretakers in a problem-solving situation where a food item was hidden in a bucket that was accessible only to the caretakers. We then examined whether horses alter their behaviours on the basis of the caretakers’ knowledge of where the food was hidden. We found that horses communicated to their caretakers using visual and tactile signals. The signalling behaviour of the horses significantly increased in conditions where the caretakers had not seen the hiding of the food. These results suggest that horses alter their communicative behaviour towards humans in accordance with humans’ knowledge state.

  Abstract Abstract— We present a study focused on a quantitative estimation of a human-horse dynamic interaction. A set of measures based on magnitude and phase coupling between heartbeat dynamics of both humans and horses in three different conditions is reported: no interaction, visual/olfactory interaction and grooming. Specifically, Magnitude Squared Coherence (MSC), Mean Phase Coherence (MPC) and Dynamic Time Warping (DTW) have been used as estimators of the amount of coupling between human and horse through the analysis of their heart rate variability (HRV) time series in a group of eleven human subjects, and one horse. The rationale behind this study is that the interaction of two complex biological systems go towards a coupling process whose dynamical evolution is modulated by the kind and time duration of the interaction itself. We achieved a congruent and consistent

statistical significant difference for all of the three indices. Moreover, a Nearest Mean Classifier was able to recognize the three classes of interaction with an accuracy greater than 70%. Although preliminary, these encouraging results allow a discrimination of three distinct phases in a real human-animal interaction opening to the characterization of the empirically proven relationship between human and horse.

  Title Non-invasive acoustic detection of wolves Type Journal Article
  Year 2016 Publication Bioacoustics Abbreviated Journal Bioacoustics  
  Volume (up) Issue Pages  
  Keywords  
  Abstract Monitoring wolves (Canis lupus) is a difficult and often expensive task due to high mobility,pack dynamic, shyness and nocturnal activity of this species. Wolves communicate acoustically trough howling, within pack and with packs of the neighbourhood. A wolf howl is a low frequency vocalization that can be transmitted over long distances and thus be used

for monitoring tasks. Animated howling survey is a current method to monitor wolves indifferent areas all over the world. Animated howling, however, may be invasive to residential wolf packs and could create possible negative reactions from local human population. Here we show that it is possible to detect wolves by recording spontaneous howling events. We measured the sound pressure level of wolf howls on captive individuals and we further found that simulated howling may be recorded and clearly identified up to a distance of 3 km. We finally conducted non-invasive acoustic detection of wolves in a free ranging population. The use of passive sound recorders may provide a powerful non-invasive tool for future wolf monitoring and thus help to established sustainable management plans for this species.

  Title Chapter 17 – Split-Brain, Split-Mind Type Book Chapter
  Year 2016 Publication The Neurology of Conciousness (Second Edition) Abbreviated Journal  
  Volume (up) Issue Pages 271-279  
  Keywords Split-brain; consciousness; lateralization; modular; left hemisphere interpreter  
  Abstract The corpus callosum anatomically and functionally connects the two cerebral hemispheres. Despite its important role in interhemispheric communication however, severing the corpus callosum produces few--if any--noticeable cognitive or behavioral abnormalities. Incredibly, split-brain patients do not report any drastic changes in their conscious experience even though nearly all interhemispheric communication ceases after surgery. Extensive research has shown that both hemispheres remain conscious following disconnection and the conscious experience of each hemisphere is private and independent of the other. Additionally, the conscious experiences of the hemispheres appear to be qualitatively different, such that the consciousness of the left hemisphere is more enriched than the right. In this chapter, we offer explanations as to why split-brain patients feel unified despite possessing dual conscious experiences and discuss how the divided consciousness of split-brain patients can inform current theories of consciousness.

  Title Dominance Hierarchies in Horses: Comparing and Contrasting Different Methods for Assessing Hierarchies Type Journal Article
  Year 2016 Publication Ursidae: The Undergraduate Research Journal at the University of Northern Colorado Abbreviated Journal  
  Volume (up) 5 Issue 3 Pages  
  Keywords  
  Abstract Understanding animal social structures is imperative when it comes to the care, housing and handling of large herd animals. Knowing how hierarchies are structured, along with environmental and physiological aspects that may affect them, will allow owners and breeders to house and care for their animals. The aim of my study was to better understand two methods used to assess dominance hierarchies in horses, Equus caballus, and to predict which method would be more useful for owners housing domestic horses. I designed an experiment where I compared a structured method, the paired feeding test, with behavioral observations from the horses’ natural setting. I hypothesized that the structured method would not conclude the same dominance hierarchy as the natural observations. I also hypothesized that traits of the horses, such as size or age, would correlate with the hierarchy ranking within a herd. A herd of six individual horses from a small ranch east of Platteville, Colorado was used to test the two methods. I found that the two methods measured different hierarchies. The paired feeding test showed no correlations to any of the physical measurements, as well as did not provide a hierarchy that was similar to the natural dominance observations of the horses. Natural observations established a more linear hierarchy and had significant correlations with weight and overall body size. The results indicate that the paired feeding test may not be a valid method for establishing dominance hierarchies within domestic horses housed in a small range.

I recommend use of natural observations over paired feeding tests for ranchers, breeders or owners trying to understand the dominance hierarchies among their herds.
