Title Effects of a therapeutic riding program on at-risk and special education children Type Journal Article
Year 2006 Publication Journal of the American Veterinary Medical Association Abbreviated Journal J Am Vet Med Assoc
Volume 228 Issue 1 Pages 46-52
Keywords Adolescent; Anger; Animals; *Bonding, Human-Pet; Child; Child Behavior; *Child Psychology; Disabled Persons/*psychology/rehabilitation; Female; Horses; Humans; Mainstreaming (Education); Male; Mothers/*psychology; Occupational Therapy/*methods; Recreation; Self Efficacy; Sports/*psychology
Abstract (up) OBJECTIVE: To determine the effects of a therapeutic riding program on psychosocial measurements among children considered at risk for poor performance or failure in school or life and among children in special education programs. DESIGN: Observational study. POPULATION: 17 at-risk children (6 boys and 11 girls) and 14 special education children (7 boys and 7 girls). PROCEDURE: For the at-risk children, anger, anxiety, perceived self-competence, and physical coordination were assessed. For the special education children, anger and cheerfulness were measured, and the children's and their mothers' perceptions of the children's behavior were assessed. Measurements were made before and after an 8-session therapeutic riding program. RESULTS: For boys enrolled in the special education program, anger was significantly decreased after completion of the riding program. The boys' mothers also perceived significant improvements in their children's behavior after completion of the program. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggest that an 8-session therapeutic riding program can significantly decrease anger in adolescent boys in a special education program and positively affect their mothers' perception of the boys' behavior.

Title Stress-related behaviors among horses used in a therapeutic riding program Type Journal Article
Year 2006 Publication Journal of the American Veterinary Medical Association Abbreviated Journal J Am Vet Med Assoc
Volume 228 Issue 1 Pages 39-45
Keywords Adult; Animals; Behavior, Animal/*physiology; Child; *Disabled Persons; Female; Horses/*psychology; Humans; Male; *Mentally Disabled Persons; Occupational Therapy/methods; Recreation; Risk Factors; Stress/*veterinary
Abstract (up) OBJECTIVE: To determine whether therapeutic riding resulted in higher levels of stress or frustration for horses than did recreational riding and whether therapeutic riding with at-risk individuals was more stressful for the horses than was therapeutic riding with individuals with physical or emotional handicaps. DESIGN: Observational study. ANIMALS: 14 horses in a therapeutic riding program. PROCEDURE: An ethogram of equine behaviors was created, and horses were observed while ridden by 5 groups of riders (recreational riders, physically handicapped riders, psychologically handicapped riders, at risk children, and special education children). Number of stress-related behaviors (ears pinned back, head raised, head turned, head tossed, head shaken, head down, and defecation) was compared among groups. RESULTS: No significant differences in mean number of stress-related behaviors were found when horses were ridden by recreational riders, physically handicapped riders, psychologically handicapped riders, or special education children. However, mean number of stress-related behaviors was significantly higher when horses were ridden by the at-risk children. CONCLUSIONS AND CLINICAL RELEVANCE: Results suggest that for horses in a therapeutic riding program, being ridden by physically or psychologically handicapped individuals is no more stressful for the horses than is being ridden in the same setting by recreational riders. However, at-risk children caused more stress to the horses, suggesting that the time horses are ridden by at-risk children should be limited both daily and weekly.

Title Ophthalmic examination findings of Thoroughbred racehorses in Australia Type Journal Article
Year 2006 Publication Veterinary Ophthalmology Abbreviated Journal Vet Ophthalmol
Volume 9 Issue 2 Pages 95-100
Keywords Animals; Cataract/epidemiology/veterinary; Diagnostic Techniques, Ophthalmological/veterinary; Eye Diseases/diagnosis/epidemiology/*veterinary; Female; Horse Diseases/diagnosis/*epidemiology; Horses; Male; Prevalence; Victoria/epidemiology
Abstract (up) OBJECTIVE: To record the prevalence and document the types of eye disease in population of Thoroughbred racehorses in Victoria, Australia. DESIGN: Prospective study. ANIMALS: Two hundred four Thoroughbred racehorses. PROCEDURE: All horses and both eyes were examined at four metropolitan and two country racing stable complexes. Ophthalmic exam was performed following dark adaptation with a transilluminator, biomicroscope, and direct ophthalmoscope. Intraocular pressures were measured when indicated. Both pupils were dilated with tropicamide when indicated. RESULTS: One hundred eighty-two (89.2%) flat-racing and 22 (10.8%) jump-racing (hurdle or steeple) horses were examined. Age range: 2-9 years (mean 3.7 years, median 3); 97 (47.5%) male-neuter, 74 (36. 3%) female, 33 (16.2%) male. Potential vision-threatening eye disease was present in 15 (7.4%) different horses: complete lenticular cataracts 3, posterior lens luxation and cataract 1, large peripapillary 'butterfly' inactive lesions 3, large peripapillary 'butterfly' active lesions 2, peripapillary focal inactive 'bullet hole' chorioretinal lesions (> 20) 5, optic nerve atrophy 1. Non-vision threatening eye disease was present in 117 (57.4%) different horses, involving one or more ocular structures: lower eyelid scars 3; periocular fibropapillomatous disease 1; third eyelid squamous cell carcinoma 1; corneal scars 6; corneal band opacity 2; anterior iris synechia 1; developmental cataracts 36 (17.2%); peripapillary focal inactive 'bullet hole' chorioretinal lesions (< 20) 103 (50.0%); linear peripapillary hyperpigmentation bands 16 (7.9%). Unusual variations of normal ocular anatomy and colobomata was recorded in 11 (5.4%) different horses: granular iridica hypoplasia 3, granular iridica hyperplasia 2, multilobular granular iridica cyst 1, microcornea 1, hyaloid remnant 1, rotated optic nerve head 1, coloboma of the lens 1, atypical coloboma of the retina 1. CONCLUSIONS: This survey demonstrates that the prevalence of vision-threatening eye disease in racing horses may be greater than previously perceived, and highlights the importance of ocular examination within any routine physical examination of horses.

Title Faithful replication of foraging techniques along cultural transmission chains by chimpanzees and children Type Journal Article
Year 2006 Publication Proceedings of the National Academy of Sciences of the United States of America Abbreviated Journal Proc. Natl. Acad. Sci. U.S.A.
Volume 103 Issue 37 Pages 13878-13883
Keywords Animals; Child, Preschool; Humans; *Imitative Behavior; Pan troglodytes/*psychology
Abstract (up) Observational studies of wild chimpanzees (Pan troglodytes) have revealed population-specific differences in behavior, thought to represent cultural variation. Field studies have also reported behaviors indicative of cultural learning, such as close observation of adult skills by infants, and the use of similar foraging techniques within a population over many generations. Although experimental studies have shown that chimpanzees are able to learn complex behaviors by observation, it is unclear how closely these studies simulate the learning environment found in the wild. In the present study we have used a diffusion chain paradigm, whereby a behavior is passed from one individual to the next in a linear sequence in an attempt to simulate intergenerational transmission of a foraging skill. Using a powerful three-group, two-action methodology, we found that alternative methods used to obtain food from a foraging device (“lift door” versus “slide door”) were accurately transmitted along two chains of six and five chimpanzees, respectively, such that the last chimpanzee in the chain used the same method as the original trained model. The fidelity of transmission within each chain is remarkable given that several individuals in the no-model control group were able to discover either method by individual exploration. A comparative study with human children revealed similar results. This study is the first to experimentally demonstrate the linear transmission of alternative foraging techniques by non-human primates. Our results show that chimpanzees have a capacity to sustain local traditions across multiple simulated generations.

Title Animal Communication: Parent-Offspring Type Book Chapter
Year 2006 Publication Encyclopedia of Language & Linguistics Abbreviated Journal
Volume Issue Pages 284-288
Keywords Begging Strategies; Communication; Competition; Feeding Strategies; Fitness; Parental Care; Parent-Offspring Conflict; Recognition; Sibling Conflict
Abstract (up) Parent-offspring communication has evolved under strong selection to guarantee that the valuable resource of parental care is expended efficiently on raising offspring. To ensure allocation of parental care to their own offspring, individual recognition becomes established in higher vertebrates when the young become mobile at a time when a nest site can no longer provide a safe cue to recognition. Such recognition needs to be established by rapid, sometimes imprinting-like, processes in animals producing precocial offspring. In parents, offering strategies that stimulate feeding and entice offspring to approach the right site have evolved. Such parental signals can be olfactory, acoustic, or visual. In offspring, begging strategies involve shuffling for the best place to obtain food – be this the most productive teat or the best position in the nest. This involves signals that make the offspring particularly obvious to the parent. Parents often feed young according to their signaling intensity but may also show favoritism for weaker offspring. Offspring signals also serve to communicate the continuing presence of the young and may thereby maintain brood-care behavior in parents. Internal processes in parents may end parental care irrespective of further signaling by offspring, thus ensuring that offspring cannot manipulate parents into providing substantially more care than is optimal for their own fitness.

Title Use of a single-code/default strategy by pigeons to acquire duration sample discriminations Type Journal Article
Year 2006 Publication Learning & behavior : a Psychonomic Society publication Abbreviated Journal Learn Behav
Volume 34 Issue 4 Pages 340-347
Keywords Animals; Behavior, Animal/*physiology; Columbidae; *Discrimination (Psychology); *Reaction Time; Retention (Psychology); *Signal Detection (Psychology)
Abstract (up) Past evidence that pigeons may adopt a single-code/default strategy to solve duration sample discriminations may be attributable to the similarity between the intertrial interval (ITI) and the retention interval. The present experiments tested whether pigeons would adopt a single-code/default strategy when possible ITI-retention-interval ambiguity was eliminated and sample salience was increased. Previous studies of duration sample discriminations that have purported to show evidence for the use of a single-code/default coding strategy have used durations of 0, 2, and 10 sec (Zentall, Klein, and Singer, 2004). However, the results of Experiment 1 suggest that the use of a 0-sec sample may produce an artifact resulting in inadvertent present/absent sample matching. In Experiment 2, when pigeons were trained with three nonzero duration samples (2, 8, and 32 sec), clear evidence for the use of a single-code/default strategy was found.

Title Can wild common marmosets (Callithrix jacchus) solve the parallel strings task? Type Journal Article
Year 2006 Publication Animal Cognition Abbreviated Journal Anim. Cogn.
Volume 9 Issue 3 Pages 229-233
Keywords Animals; Animals, Laboratory; Animals, Wild; Attention; Callithrix/*psychology; *Cognition; *Concept Formation; Female; Male; *Pattern Recognition, Visual; *Problem Solving
Abstract (up) Patterned string tasks are a test of perceptual capacity and the understanding of means-end connections. Primates can solve complex forms of this task in laboratories. However, this may not indicate the level of such cognition that is commonly employed in the wild, where decision-making time is often short and distractions such as predator avoidance and competition between conspecifics are often prevalent. The current study tests whether wild common marmosets (Callithrix jacchus) can successfully complete the simplest form of the patterned string task, parallel strings, while in their natural environment. Although 12 out of 13 marmosets could successfully complete the task, in previous laboratory-based studies on primates, the errors at this task by all primate species tested were consistently lower than in the present study. This is probably explained by the added difficulties imposed by the natural setting of the task in the present study, exemplified by a significant increase in observed vigilance behaviour by subject animals prior to attempts at the task that were unsuccessful. The undertaking of such tasks by common marmosets in situ probably provides a more reasonable representation of the levels of cognitive capacity expressed by this species in the wild than do laboratory-based studies of the task.

Title Vergleich verschiedener Methoden zur Angstextinktion bei Pferden Type Manuscript
Year 2006 Publication Abbreviated Journal
Volume Issue Pages
Keywords
Abstract (up) Pferde sind Fluchttiere. Ihr Fluchtinstinkt bewirkt, dass sie sich leicht erschrecken und auch in

diversen Situationen mit Flucht reagieren. Diese Tatsache ist den meisten Reitern bekannt,

nur ist es für den Menschen teilweise schwer, mit dieser Eigenschaft auszukommen und sie zu

verstehen oder gar nachzuvollziehen. So kommt es häufig zu Unfällen, die aus der Angst der

Pferde resultieren, jedoch vermeidbar gewesen wären, hätte man ankündigende Signale früher

erkannt. Des Weiteren kann die Angst eines Pferdes auch durch eine (Ver-) Weigerung,

bestimmte Dinge zu tun, sichtbar werden. Diese Weigerung wird in der Reiterei gerne als

„Bockigkeit“ und „Ungehorsam“ des Pferdes interpretiert und führt nicht selten zu einer

Bestrafung. Insgesamt kann man sagen, dass angstauslösende Reize und die Reaktionen des

Pferdes darauf oft falsch eingeschätzt oder falsch interpretiert werden und in der Folge auch

falsch damit umgegangen wird. Ein Grund dafür ist sicher das fehlende Wissen über das

Verhalten des Pferdes. Mit der vorliegenden Diplomarbeit soll ein Beitrag geleistet werden,

das Pferd in seinem Angstverhalten besser zu verstehen. Ziel der Arbeit war es, das Verhalten

des Pferdes bei verschiedenen Intensitäten von Angst zu untersuchen. Des Weiteren wurden

Methoden untersucht, mit denen man die Angst von Pferden vor bestimmten Reizen und

Situationen potentiell lindern kann, was letztendlich auch der Unfallvorbeugung dient.

Die vorliegende Diplomarbeit wurde am Haupt- und Landesgestüt Marbach durchgeführt; 24

Junghengste standen hierfür zur Verfügung. Darunter waren 18 Deutsche Warmblüter, 3

Vollblutaraber und 3 Schwarzwälder Füchse (Kaltblüter), somit war auch ein Rassenvergleich

möglich.

In einem ersten Teil der Arbeit wurde untersucht, wie sich Angst bei Pferden äußert. Hierfür

wurde ausgenutzt, dass Pferde ganz generell vor unbekannten, neuen Gegenständen Angst

haben (= Neophobie). Zur Angstauslösung dienten als Konfrontationsgegenstände ein

Sonnenschirm und eine Plastikplane. Beide Gegenstände waren für die Testpferde unbekannt.

Das Verhalten sowie die Herzrate der Tiere wurden während aller Versuche beobachtet und

quantifiziert. Nacheiner ersten Konfrontation wurden die Pferde an die Objekte gewöhnt

(Extinktionstraining = Angstlöschung) und beobachtet welche Verhaltensymptome sich

während dieser Gewöhnung (= Verlust der Neophobie) verändern. Die Hypothese war, dass

tatsächliche Angstsymptome während der Gewöhnung immer seltener zu beobachten sind.

Zusammenfassung III

Als Verhaltensweisen für Angst konnten Ausweichbewegungen und Flucht, Lautäußerungen

(Prusten und Schnauben), das Anspannen der Halsmuskulatur sowie das Vordrücken der

Oberlippe identifiziert werden. Darüber hinaus wurde gezeigt, dass Abstufungen im

Angstverhalten möglich sind: Bei sehr hohem Angstlevel sind Fluchtreaktionen zu

beobachten. Bei mittlerem Angstlevel treten Ausweichbewegungen im Schritt und

Lautäußerungen (Prusten und Schnauben) auf, bei geringem Angstlevel wird die

Halsmuskulatur angespannt und die Oberlippe vorgedrückt.

Im Zweiten Teil der Arbeit sollten verschiedene Methoden zur Angst-Extinktionauf ihre

Wirksamkeit hin untersucht werden. Verwendet wurde in verschiedenen Testgruppen die

Methode der Desensibilisierung (d.h. leichte, schrittweise stärker werdende Exposition

gegenüber dem angstauslösenden Reiz), die Desensibilisierung mit Gegenkonditionierung

(positive Verstärkung) durch Streicheln bzw. Reiben des Halses und die Desensibilisierung

mit Gegenkonditionierung durch Futterbelohnung. Als Kontrollgruppe dienten Pferde, die

ohne eine Konfrontation mit dem angstauslösenden Reiz nur über den Versuchplatz geführt

wurden.

Während des Extinktionstrainings konnte beobachtet werden, dass die Desensibilisierung mit

Gegenkonditionierung zu einer schnelleren Extinktion führt als ohne Gegenkonditionierung.

Allerdings zeigte ein Vergleich mit der Kontrollgruppe, die das Extinktionstraining nicht

erfahren hatte, den gleichen Verlust an Angstverhalten wie die Gruppen mit Extinktionstraining.

Dieses Ergebnis wurde so interpretiert, dass die wiederholte Exposition gegenüber

angstauslösenden Reizen bei den durchgeführten Verhaltenstests zwar eine Rolle spielt, doch

dass auch allein die Beschäftigung mit den Tieren zu einem Verlust von Angstverhalten führt

(wahrscheinlich auch aufgrund eines wachsenden Vertrauens zur Führperson, die über das

komplette Experiment hin die Gleiche blieb).

Title Blind imitation in pigeons, Columba livia Type Journal Article
Year 2006 Publication Animal Behaviour. Abbreviated Journal Anim. Behav.
Volume 72 Issue 2 Pages 287-296
Keywords
Abstract (up) Pigeons that had been trained with a food reward both to peck at and to step on a horizontal plate were allowed to observe a conspecific demonstrator pecking at or stepping on the plate before a test in which the observers were not rewarded for either pecking or stepping. In experiment 1, the demonstrators were not rewarded while being observed. In spite of this, the observers provided evidence of imitation: those that had observed pecking made a greater proportion of pecking responses on test than observers of stepping. In experiment 2, each observer was exposed to a pecking or a stepping conspecific on two occasions. On one occasion, the demonstrator received a food reward for each demonstrated response (continuous reinforcement condition), and on the other the demonstrator's responses were rewarded only rarely (variable interval condition). The observers provided equally strong evidence of imitation in each of these conditions; on test, they made proportionally more of the observed response both when the demonstrators had been richly rewarded and when they had been rarely rewarded. These results show that pigeons engage in `blind' imitation, that is, their imitative behaviour is not always guided by observational learning about response outcomes.
