Title Reinforcement as a mediator of the perception of humans by horses (Equus caballus) Type Journal Article
Year 2010 Publication Animal Cognition Abbreviated Journal Anim. Cogn.
Volume 13 Issue 5 Pages 753-764-764
Keywords (down) Perception of humans – Human/animal relationship – Positive reinforcement – Negative reinforcement – Equus caballus
Abstract A central question in the interspecific human/animal relationship is how domestic animals perceive humans as a significant element of their environment. In this study, we tested the hypothesis that the use of positive or negative reinforcement in horse training may have consequences on the animals’ perception of humans, as a positive, negative or neutral element. Two groups of ponies were trained to walk backwards in response to a vocal order using either positive or negative reinforcement. Heart rate monitors and behavioural observations were used to assess the animals’ perception of humans on the short (just after training) and long (5 months later) terms. The results showed that the type of reinforcement had a major effect on the subsequent animals’ perception of familiar and unfamiliar humans. Negative reinforcement was rapidly associated with an increased emotional state, as revealed by heart rate measurements and behavioural observations (head movements and ears laid back position). Its use led the ponies to seek less contact with humans. On the contrary, ponies trained with positive reinforcement showed an increased interest in humans and sought contact after training. This is especially remarkable as it was reached in a maximum of 5 sessions of 1 to 3 min (i.e. 5 to 15 min) and had lasting effects (visible after 5 months). Even learning was positively influenced by positive reinforcement. Overall, horses seem capable of associating humans to particular experiences and display extended long-term memory abilities.

Title Seeing two faces together: preference formation in humans and rhesus macaques Type Journal Article
Year 2014 Publication Abbreviated Journal Animal Cognition
Volume Issue Pages 1-13
Keywords (down) Humans; Rhesus macaques; Preferences; Faces; Eye-tracking
Abstract Humans, great apes and old world monkeys show selective attention to faces depending on conspecificity, familiarity, and social status supporting the view that primates share similar face processing mechanisms. Although many studies have been done on face scanning strategy in monkeys and humans, the mechanisms influencing viewing preference have received little attention. To determine how face categories influence viewing preference in humans and rhesus macaques (Macaca mulatta), we performed two eye-tracking experiments using a visual preference task whereby pairs of faces from different species were presented simultaneously. The results indicated that viewing time was significantly influenced by the pairing of the face categories. Humans showed a strong bias towards an own-race face in an Asian–Caucasian condition. Rhesus macaques directed more attention towards non-human primate faces when they were paired with human faces, regardless of the species. When rhesus faces were paired with faces from Barbary macaques (Macaca sylvanus) or chimpanzees (Pan troglodytes), the novel species’ faces attracted more attention. These results indicate that monkeys’ viewing preferences, as assessed by a visual preference task, are modulated by several factors, species and dominance being the most influential.

Title Logit models and logistic regressions for social networks: II. Multivariate relations Type Journal Article
Year 1999 Publication The British Journal of Mathematical and Statistical Psychology Abbreviated Journal Br J Math Stat Psychol
Volume 52 ( Pt 2) Issue Pages 169-193
Keywords (down) Humans; Markov Chains; *Models, Statistical; Organization and Administration; *Social Support
Abstract The research described here builds on our previous work by generalizing the univariate models described there to models for multivariate relations. This family, labelled p*, generalizes the Markov random graphs of Frank and Strauss, which were further developed by them and others, building on Besag's ideas on estimation. These models were first used to model random variables embedded in lattices by Ising, and have been quite common in the study of spatial data. Here, they are applied to the statistical analysis of multigraphs, in general, and the analysis of multivariate social networks, in particular. In this paper, we show how to formulate models for multivariate social networks by considering a range of theoretical claims about social structure. We illustrate the models by developing structural models for several multivariate networks.

Title Reactivity to humans: A temperament trait of horses which is stable across time and situations Type Journal Article
Year 2008 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.
Volume 114 Issue 3-4 Pages 492-508
Keywords (down) Horse; Equus caballus; Reactivity to humans; Temperament trait; Personality; Behavioural consistency
Abstract The aim of this study was to test the existence of a “reactivity-to-humans” trait which is stable over time and across situations. For this purpose, four test situations were repeated on the same animals at 8 months, 1.5 years (N = 110 horses) and 2.5 years of age (N = 54 horses). These situations involved a “familiar passive human test” during which a familiar person stayed motionless in the test pen, a “familiar active human test” and an “unfamiliar active human test” during which a familiar or unfamiliar person attempted to touch the horse, and a “halter-fitting and heart-rate measurement test”, during which the horse was haltered and equipped with a surcingle and then had its heart-rate measured. Many behavioural variables were recorded during the tests, and correlations between ages and variables measured during other situations were investigated. When correlations were found, we concluded that the variables corresponded to temperament traits which are stable over time and across situations. The horses tested were divided into four groups according to breed (Anglo-Arab and Welsh) and year of birth (2001 and 2002). Data for each group were analysed separately with Spearman rank correlations. Regarding stability over time, there was a strong correlation between ages in the frequency of licking/nibbling the passive human, the time taken by a familiar or unfamiliar person to touch the horse, and the time taken to fit a halter (e.g. the time taken to touch the horse's muzzle was significantly correlated between ages in 7 out of the 8 possible cases: 0.40 <= R <= 0.67). Regarding stability across situations, results indicate that the more frequently a horse sniffed, licked or nibbled a passive human, the easier it was for either a familiar or unfamiliar active human to touch and halter it. Moreover, a horse which could be touched easily by a familiar human could also be touched and haltered easily by an unfamiliar human. These behaviours, which are linked directly to humans, therefore indicate good stability over time and across situations. In conclusion, this stability suggests the existence of a “reactivity-to-humans” temperament trait, whether the human is passive or active, familiar or unfamiliar. When the animals do not have frequent contact with humans, this reactivity is stable over time and can be measured as early as 8 months of age using the behavioural variables cited above.

Title Cross-modal recognition of human individuals in domestic horses (Equus caballus) Type Journal Article
Year 2012 Publication Abbreviated Journal Animal Cognition
Volume 15 Issue 4 Pages 623-630
Keywords (down) Cross-modal; Recognition of humans; Horse; Equus caballus; Human–horse interaction; Animal cognition; Visual recognition; Auditory recognition; Voice discrimination; Interspecific
Abstract This study has shown that domestic horses are capable of cross-modal recognition of familiar humans. It was demonstrated that horses are able to discriminate between the voices of a familiar and an unfamiliar human without seeing or smelling them at the same moment. Conversely, they were able to discriminate the same persons when only exposed to their visual and olfactory cues, without being stimulated by their voices. A cross-modal expectancy violation setup was employed; subjects were exposed both to trials with incongruent auditory and visual/olfactory identity cues and trials with congruent cues. It was found that subjects responded more quickly, longer and more often in incongruent trials, exhibiting heightened interest in unmatched cues of identity. This suggests that the equine brain is able to integrate multisensory identity cues from a familiar human into a person representation that allows the brain, when deprived of one or two senses, to maintain recognition of this person.

Title Effect of cholesterol-lowering diet on mortality from coronary heart disease and other causes Type Journal Article
Year 1979 Publication Circulation Abbreviated Journal Circulation
Volume 59 Issue 1 Pages 1-7
Keywords (down) Coronary Disease/blood/*mortality/prevention & control; Dairy Products; *Dietary Fats; *Fats, Unsaturated; Finland; Humans; Hypercholesterolemia/complications/*diet therapy/mortality; Male; Middle Aged; Neoplasms/mortality
Abstract International statistics indicate that there is a close correlation between the consumption of saturated fats (dairy fats and meat fats) and the mortality from coronary heart disease (CHD), and this conception has been confirmed by many epidemiological studies. Such studies alone, however, cannot prove the existence of a cause-and-effect relationship between these two variables; dietary intervention trials are needed. The Finnish Mental Hospital Study was such a trial, conducted in two hospitals near Helsinki in 1959--1971. Practically total replacement of dairy fats by vegetable oils in the diets of these hospitals was followed by a substantial reduction in the mortality of men from CHD. Total mortality also appeared to be reduced. As to the causes of death other than CHD, none was significantly influenced by dietary change. This was also true for malignant neoplasms. To alleviate the burden of CHD on public health, many investigators have recommended important changes in the quantity and quality of dietary fats.

Title Awareness in domesticated animals--concepts and definitions Type Journal Article
Year 1998 Publication Applied Animal Behaviour Science Abbreviated Journal Appl. Anim. Behav. Sci.
Volume 57 Issue 3-4 Pages 181-200
Keywords (down) Complex mind; Awareness; Humans; Domesticated animals; Conscious state
Abstract Humans will probably never experience the awareness of another species, but adopting a broad concept of awareness leads to the conclusion that other species have some awareness. The existence of a more complex mind in humans, compared with other species, leads some to suggest that awareness only exists in humans. We postulate that humans possess a significantly increased level of awareness, facilitated in particular by the acquisition of language, but that generally animals possess a level of awareness that is appropriate to their needs. Categories of awareness can be devised by identifying levels, such as are used in the identification of the conscious state in humans, or by ranking states of awareness in order of complexity. A scheme is proposed that combines these two approaches, which is considered suitable for use with domesticated animals. The advantages of identifying awareness as being sensation-, perception- or cognition-based are discussed, as well as the possibility of a scheme based on the degree and site of CNS processing. Finally, the acquisition of awareness by learning and inheritance is considered, and it is argued that in variable environments, animals will evolve increased awareness, whereas in very stable environments the energetic cost of awareness will encourage the evolution of less aware animals.

Title Hidden visual processes Type Journal Article
Year 1983 Publication Scientific American Abbreviated Journal Sci Am
Volume 248 Issue 2 Pages 94-103
Keywords (down) Color Perception/*physiology; Humans; Motion Perception/physiology; Ocular Physiology; Vision; Visual Perception/*physiology
Abstract Isoluminant stimulus is an image whose edges are defined only by a change in color, not by change in brightness. The stimulus here is imperfect: the blue parts and the green parts of the image are only as nearly equal in brightness as they can be on the printed page. Moreover, the change in brightness beyond the edge of the page is apparent, and so is the fact that the reader is holding the magazine at reading distance. When such cues are removed under laboratory conditions, subjects faced with an isoluminant stimulus prove unable to bring its edges into focus. This deficiency contributes to making a familiar face hard to recognize. The experiment indicates that the brain process underlying visual accommodation (the focusing of the eyes) cannot “see” color; it is a hidden process distinct from the processes that lead to perception. The image shows Groucho Marx as he appeared in the motion picture Horse Feathers.
