	Title	*On the significance of puzzling behaviours: what do yawning and adult play tell us about horse (Equus caballus) welfare?*			Type	Conference Article
	Year	2012	Publication	Proceedings of the 2. International Equine Science Meeting	Abbreviated Journal	Proc. 2. Int. Equine. Sci. Mtg
	Volume	in press	Issue		Pages
	Keywords	welfare indicators, yawning, adult play, altered welfare, horse
	Abstract	Some behaviours remain a mystery and their determinants are still uncertain. Here we propose a critical interpretation of two puzzling behaviours, i.e. yawning and adult play, recorded in large samples of domestic horses kept in sub-optimal conditions (e.g. time-restricted feeding practices, social isolation). Yawning is involved in behavioural state changes, especially in quiet contexts of motor relaxation, but seems also to be triggered by stress and emotional contexts. Thus, we investigated specific correlates of yawning and stereotypic behaviours in two large samples of working horses (n1 = 87, n2 = 59). A clear co-occurrences of yawning and stereotypic behaviours appeared: stereotypic horses yawned more than the non-stereotypic horses (Fisher test, p < 0.02), yawning increased at the same time periods as stereotypic behaviours did (Wilcoxon tests, p < 0.05 to 0.001) and yawning frequency was even sometimes positively correlated with stereotypic behaviour frequencies (Spearman correlations, p < 0.005). Play, more typical of young stages in healthy individuals, occurs rarely at adult stages but then more often in captive/domestic animals (which can be challenging to welfare) than in animals living in natural conditions. Thus, we tested the hypothesis that adult play may reflect altered welfare states in horses, where, as in several species, play rarely occurs at adult stages in natural conditions. We observed the behaviour (in particular social play) of 29 adult riding school horses during occasional outings in a paddock and measured several stress indicators (health-related, behavioural and physiological) when these horses were in their home individual boxes. Results revealed that the number of horses and rates of adult play appeared very high compared to field report data and that most stress indicators measured differed between “players” and “non-players”, revealing that most “playful” animals were more prone to suffer from chronic stress contrarily to “non-playful” horses (Fisher, Chi-square, Mann-Whitney and Spearman correlation tests, p < 0.05 to 0.001). Altogether, these results show that yawning and adult play can both reflect altered welfare states in horses, highlighting that these puzzling behaviours should not be considered, as currently thought, as reliable indicators of good welfare states and / or expression of positive emotions.

	Title	Adults may be used to alleviate weaning stress in domestic foals (Equus caballus)			Type	Journal Article
	Year	2012	Publication	Physiology & Behavior	Abbreviated Journal
	Volume	106	Issue	4	Pages	428-438
	Keywords	Weaning; Social influence; Abnormal behaviours; Young-adult interactions; Welfare; Horse
	Abstract	The present study aims to investigate whether the presence of unrelated adult horses at weaning would reduce the social stress of weaning and the emergence of undesirable behaviours. We tested this hypothesis in 32 domestic foals by comparing short and medium term behavioural and physiological responses to weaning in foals maintained in homogeneous groups of peers (PW) to those of foals grouped with both peers and unrelated adults (AW). In total, three trials were conducted, which each trial consisting of one AW group and one PW group. In all foals, weaning was followed by increased vocalization, increased locomotion and increased salivary cortisol concentration. However, signs of stress were less pronounced and shorter in duration in weanlings housed with unrelated adults (e.g. whinnies: p < 0.05; salivary cortisol: p < 0.05). Only foals without adults exhibited increased aggressiveness towards peers (p < 0.05) and abnormal behaviours (p < 0.05) such as excessive wood-chewing and redirected sucking towards peers. In conclusion, introducing adults to minimize weaning stress in foals and later on aggressiveness and abnormal behaviours appears as the most promising approach to date.

	Title	The running horse stops: the hypothetical role of the eyes in imagery of movement			Type	Journal Article
	Year	1999	Publication	Perceptual and motor skills	Abbreviated Journal	Percept Mot Skills
	Volume	89	Issue	3 Pt 2	Pages	1088-1092
	Keywords	Adult; Cerebral Cortex/physiology; Eye Movements/physiology; Female; Functional Laterality/physiology; Head/physiology; Humans; Imagination; Models, Neurological; Motion Perception; Movement/physiology; Ocular Physiology; *Optical Illusions; Posture/physiology
	Abstract	To examine the hypothetical role of the eyes in visual mental imagery of movement 72 undergraduate women students in psychology were asked to imagine a running horse and then to produce the same mental image without moving the eyes and the head. In 59% of the subjects interesting modifications of the imagined movement appeared: 37% observed an inhibition of the movement and 19% an evident slowing up of the moving figure. The interpretation of this result was made by hypothesizing that the eyes are concretely involved in visual imagery processes.

	Title	An investigation of learning strategy supporting transitive inference performance in humans compared to other species			Type	Journal Article
	Year	2006	Publication	Neuropsychologia	Abbreviated Journal	Neuropsychologia
	Volume	44	Issue	8	Pages	1370-1387
	Keywords	Adult; Analysis of Variance; Association Learning/physiology; Cognition; Concept Formation; Female; Humans; Logic; Male; Pattern Recognition, Visual/physiology; Photic Stimulation/methods; Reaction Time/physiology
	Abstract	Generalizations about neural function are often drawn from non-human animal models to human cognition, however, the assumption of cross-species conservation may sometimes be invalid. Humans may use different strategies mediated by alternative structures, or similar structures may operate differently within the context of the human brain. The transitive inference problem, considered a hallmark of logical reasoning, can be solved by non-human species via associative learning rather than logic. We tested whether humans use similar strategies to other species for transitive inference. Results are crucial for evaluating the validity of widely accepted assumptions of similar neural substrates underlying performance in humans and other animals. Here we show that successful transitive inference in humans is unrelated to use of associative learning strategies and is associated with ability to report the hierarchical relationship among stimuli. Our work stipulates that cross-species generalizations must be interpreted cautiously, since performance on the same task may be mediated by different strategies and/or neural systems.

	Title	A horse of a different colour: do patients with semantic dementia recognise different versions of the same object as the same?			Type	Journal Article
	Year	2006	Publication	Neuropsychologia	Abbreviated Journal	Neuropsychologia
	Volume	44	Issue	4	Pages	566-575
	Keywords	Adult; Aged; Anomia/diagnosis/psychology; Atrophy; Attention; Color Perception; Dementia/diagnosis/psychology; Discrimination Learning; Dominance, Cerebral; Female; Humans; Male; Memory, Short-Term; Middle Aged; Neuropsychological Tests; Orientation; *Pattern Recognition, Visual; Reference Values; Retention (Psychology); Semantics; Size Perception; Temporal Lobe/pathology
	Abstract	Ten patients with semantic dementia resulting from bilateral anterior temporal lobe atrophy, and 10 matched controls, were tested on an object recognition task in which they were invited to choose (from a four-item array) the picture representing “the same thing” as an object picture that they had just inspected and attempted to name. The target in the response array was never physically identical to the studied picture but differed from it – in the various conditions – in size, angle of view, colour or exemplar (e.g. a different breed of dog). In one test block for each patient, the response array was presented immediately after the studied picture was removed; in another block, a 2 min filled delay was inserted between study and test. The patients performed relatively well when the studied object and target response differed only in the size of the picture on the page, but were significantly impaired as a group in the other three type-of-change conditions, even with no delay between study and test. The five patients whose structural brain imaging revealed major right-temporal atrophy were more impaired overall, and also more affected by the 2 min delay, than the five patients with an asymmetric pattern characterised by predominant left-sided atrophy. These results are interpreted in terms of a hypothesis that successful classification of an object token as an object type is not a pre-semantic ability but rather results from interaction of perceptual and conceptual processing.

	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	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.

	Abstract	A. Whiten, D. M. Custance, J.-C. Gomez, P. Teixidor, and K. A. Bard (1996) tested chimpanzees' (Pan troglodytes) and human children's (Homo sapiens) skills at imitation with a 2-action test on an “artificial fruit.” Chimpanzees imitated to a restricted degree; children were more thoroughly imitative. Such results prompted some to assert that the difference in imitation indicates a difference in the subjects' understanding of the intentions of the demonstrator (M. Tomasello, 1996). In this experiment, 37 adult human subjects were tested with the artificial fruit. Far from being perfect imitators, the adults were less imitative than the children. These results cast doubt on the inference from imitative performance to an ability to understand others' intentions. The results also demonstrate how any test of imitation requires a control group and attention to the level of behavioral analysis.

	Title	[Apropos of 5 cases of so-called “delusions of cutaneous and intestinal infestation”--psychopathologic and neuropsychological considerations]			Type	Journal Article

	Keywords	Adult; Aged; Agnosia/complications; Attitude to Health; Delusions/complications/etiology/psychology; Female; Humans; Intestines; Male; Middle Aged; Personality; Psychotherapy; Sensation; Skin
	Abstract	Five cases with so-called “Dermato- und Enterozoenwahn” are reported, and the following themes are analysed from the “multidimensional” point of view: 1) process to build the shape of the intruder which is bothering the patients, 2) behavior against the intruding small animal and attitude towards the therapeutist; their characteristic manner to make complaints, 3) premorbid personality and 4) physical findings. In regard to one of the formation types of this disease, we have postulated through the neuropsychological analysis of case 5 (somatoparaphrenic patient) that patients of the typical cases 1, 2 and 3 suffer from a special kind of agnosia (perturbation of recognition; disturbance of aperception) in which they take their abnormal body sensations for causing by the small imaginary animals. Our cases showed the importance of a premorbid personality and present life-situations in combination with physical dissolution taking part in the pathoplastic process of this particular disease.

	Title	Cognitive mechanisms of transitive inference			Type	Journal Article
	Year	2002	Publication	Experimental brain research. Experimentelle Hirnforschung. Experimentation cerebrale	Abbreviated Journal	Exp Brain Res
	Volume	146	Issue	1	Pages	1-10
	Keywords	Adolescent; Adult; Attention/physiology; Cognition/physiology; Female; Humans; Learning/physiology; Linear Models; Male; Photic Stimulation; Psychomotor Performance/physiology; Reaction Time/physiology
	Abstract	We examined how the brain organizes interrelated facts during learning and how the facts are subsequently manipulated in a transitive inference (TI) paradigm (e.g., if A<B and B<C, then A<C). This task determined features such as learned facts and behavioral goals, but the learned facts could be organized in any of several ways. For example, if one learns a list by operating on paired items, the pairs may be stored individually as separate facts and reaction time (RT) should decrease with learning. Alternatively, the pairs may be stored as a single, unified list, which may yield a different RT pattern. We characterized RT patterns that occurred as participants learned, by trial and error, the predetermined order of 11 shapes. The task goal was to choose the shape occurring closer to the end of the list, and feedback about correctness was provided during this phase. RT increased even as its variance decreased during learning, suggesting that the learnt knowledge became progressively unified into a single representation, requiring more time to manipulate as participants acquired relational knowledge. After learning, non-adjacent (NA) list items were presented to examine how participants reasoned in a TI task. The task goal also required choosing from each presented pair the item occurring closer to the list end, but without feedback. Participants could solve the TI problems by applying formal logic to the previously learnt pairs of adjacent items; alternatively, they could manipulate a single, unified representation of the list. Shorter RT occurred for NA pairs having more intervening items, supporting the hypothesis that humans employ unified mental representations during TI. The response pattern does not support mental logic solutions of applying inference rules sequentially, which would predict longer RT with more intervening items. We conclude that the brain organizes information in such a way that reflects the relations among the items, even if the facts were learned in an arbitrary order, and that this representation is subsequently used to make inferences.

	Title	Energy expenditure of horse riding			Type	Journal Article
	Year	2000	Publication	European Journal of Applied Physiology	Abbreviated Journal	Eur J Appl Physiol
	Volume	82	Issue	5-6	Pages	499-503
	Keywords	Adult; Animals; Energy Metabolism/physiology; Exercise/physiology; Exercise Test; Female; Hemodynamic Processes/physiology; Horses; Humans; Male; Oxygen Consumption/physiology; Respiratory Mechanics/physiology
	Abstract	Oxygen consumption (VO2), ventilation (VE) and heart rate (HR) were studied in five recreational riders with a portable oxygen analyser (K2 Cosmed, Rome) telemetric system, during two different experimental riding sessions. The first one was a dressage session in which the rider successively rode four different horses at a walk, trot and canter. The second one was a jumping training session. Each rider rode two horses, one known and one unknown. The physiological parameters were measured during warm up at a canter in suspension and when jumping an isolated obstacle at a trot and canter. This session was concluded by a jumping course with 12 obstacles. The data show a progressive increase in VO2 during the dressage session from a mean value of 0.70 (0.18) l x min(-1) [mean (SD)] at a walk, to 1.47 (0.28) l x min(-1) at a trot, and 1.9 (0.3) l x min(-1) at a canter. During the jumping session, rider VO2 was 2 (0.33) l x min(-1) with a mean HR of 155 beats x min(-1) during canter in suspension, obstacle trot and obstacle canter. The jumping course significantly enhanced VO2 and HR up to mean values of 2.40 (0.35) l x min(-1) and 176 beats x min(-1), respectively. The comparison among horses and riders during the dressage session shows differences in energy expenditure according to the horse for the same rider and between riders. During the jumping session, there was no statistical difference between riders riding known and unknown horses. In conclusion these data confirm that riding induces a significant increase in energy expenditure. During jumping, a mean value of 75% VO2max was reached. Therefore, a good aerobic capacity seems to be a factor determining riding performance in competitions. Regular riding practice and additional physical training are recommended to enhance the physical fitness of competitive riders.
