Title | Effect of oestrous-cycle stage on the response of mares in a novel object test and isolation test | Type | Journal Article | ||

Abstract | In various species, sex, hormonal treatments and oestrous-cycle stage have been shown to affect the animal's response in behavioural tests. Few such studies have been performed in the horse. The main aim of the present study was to investigate whether oestrous-cycle stage affects mares' response to a novel object test and isolation test and, in part, to study whether mares, assumed to suffer from oestrous-related behavioural problems, respond differently in these tests when compared with controls. Twelve mares were tested twice, in oestrus and dioestrus, in a crossover design. Seven behavioural and two heart rate variables were measured for the novel object test and two heart rate variables for the isolation test. Oestrous-cycle stage and whether a mare was classified as a 'problem' mare did not affect the mare's response. However, test order, i.e. the cycle stage a mare was tested in first, affected its reaction. This effect could partly be explained by significant differences between test occasions 1 and 2 in three behavioural variables and one heart rate variable (p < 0.05) in the novel object test. The mares explored the novel object more and had a higher mean heart rate in the first test. Exploring the novel object more could largely be attributed to those mares tested in dioestrus first, perhaps indicating that the mares in oestrus were less receptive to the novel object. The reason for the differences between test occasions could be an effect of learning or habituation. | ||||

Title | Living in gourps: Evolutionary Perspective | Type | Book Chapter | ||
Year | Publication | Social Behavior in Farm Animals | Abbreviated Journal | ||
Volume | Issue | Pages | |||
Keywords | |||||
Abstract | An understanding of social behavior is increasingly necessary in farm animal husbandry as more animals are housed in groups rather than in individual stalls or pens. There may be economic or welfare reasons for such housing. This book is the first to specifically address this important subject. The chapters fall into three broad subject areas: concepts in social behavior; species specific chapters; current issues. Authors include leading experts from Europe, North America, Australia and New Zealand. | ||||

Title | Transitive inference in animals: Reasoning or conditioned associations? | Type | Book Chapter | ||
Year | 2006 | Publication | Rational Animals? | Abbreviated Journal | |
Volume | Issue | Pages | 175-186 | ||
Keywords | |||||
Abstract | It is widely accepted that many species of nonhuman animals appear to engage in transitive inference, producing appropriate responses to novel pairings of non-adjacent members of an ordered series without previous experience of these pairings. Some researchers have taken this capability as providing direct evidence that these animals reason. Others resist such declarations, favouring instead explanations in terms of associative conditioning. Associative accounts of transitive inference have been refined in application to a simple 5-element learning task that is the main paradigm for laboratory investigations of the phenomenon, but it remains unclear how well those accounts generalise to more information-rich environments such as social hierarchies which may contain scores of individuals, and where rapid learning is important. The case of transitive inference is an example of a more general dispute between proponents of associative accounts and advocates of more cognitive accounts of animal behaviour. Examination of the specific details of transitive inference suggests some lessons for the wider debate. |
