Title Ecological correlates of social learning: problems and solutions for the comparative method Type Journal Article
Year 1995 Publication Behavioural Processes Abbreviated Journal Behav. Process.
Volume 35 Issue 1-3 Pages 163-171
Keywords (up) Adaptive specialization; Social learning; Comparative method
Abstract Interspecific variation in learning and cognition is often accounted for by adaptive specialization, an ecological framework where variation between species in the environmental problems they face is thought to select for quantitatively and/or qualitatively different abilities. Adaptive specialization theory relies on the comparative method for testing its hypotheses and assumes a naturally selected basis for the predicted differences. This review examines social learning as a specialization to group-living and scramble feeding competition. It points out one important problem with current studies in the area, the lack of quantitative controls for confounding variables that may cause type 1 or 2 error in comparative tests. A linear regression technique is proposed to measure and remove interspecific differences on control tests for which there is no predicted adaptive specialization; as in other areas of comparative biology, the adaptive prediction is then made on the residual deviation from the regression of these confounding variables. Examples are given from research on opportunistic Columbids, the group-living feral pigeon Columbia livia, and the territorial Zenaida dove, Zenaida aurita.

Title Comparison of the stride kinematics of the collected, medium, and extended walks in horses Type Journal Article
Year 1995 Publication American Journal of Veterinary Research Abbreviated Journal Am J Vet Res
Volume 56 Issue 7 Pages 849-852
Keywords (up) Analysis of Variance; Animals; *Gait; Horses/*physiology; *Locomotion; Motion Pictures; Physical Conditioning, Animal; Walking
Abstract Six horses, highly trained for dressage competition, were used to study the stride kinematics of the walk, and to compare the kinematics of the collected, medium, and extended walks. Horses were filmed in a sagittal plane at a rate of 150 frames/s; temporal, linear, and angular data were extracted from the films. Results of ANOVA and Duncan's multiple range test indicated that the speed of the collected walk (1.37 m/s) was significantly (P < 0.01) slower than that of the medium (1.73 m/s) and extended (1.82 m/s) walks, values for which were not significantly different from each other. The increase in speed was associated with a significant increase in stride length, from 157 cm in the collected walk to 193 cm in the extended walk. This was a result of an increase in the over-tracking distance, whereas there was no significant difference in the distance between lateral placements of the limbs. Stride duration decreased (P < 0.01) from the collected walk (1,159 ms) to the extended walk (1,064 ms). Angles of the metacarpal and metatarsal segments, measured on the palmar/ plantar aspect, were higher at impact and lower at lift off in the collected than in the extended walk (P < 0.01). This indicated greater range of angular motion of this segment during the stance phase in the extended walk. Only 1 of the 6 horses had a regular 4-beat rhythm of the footfalls, with equal time elapsing between the lateral and diagonal footfalls.

Title Using self-view television to distinguish between self-examination and social behavior in the bottlenose dolphin (Tursiops truncatus) Type Journal Article
Year 1995 Publication Consciousness and Cognition Abbreviated Journal Conscious Cogn
Volume 4 Issue 2 Pages 205-224
Keywords (up) Animal Communication; Animals; *Attention; Discrimination Learning; Dolphins/*psychology; Female; Male; *Self Concept; *Social Behavior; *Television; *Visual Perception
Abstract In mirror mark tests dolphins twist, posture, and engage in open-mouth and head movements, often repetitive. Because postures and an open mouth are also dolphin social behaviors, we used self-view television as a manipulatable mirror to distinguish between self-examination and social behavior. Two dolphins were exposed to alternating real-time self-view (“mirror mode”) and playback of the same to determine if they distinguished between them. The adult male engaged in elaborate open-mouth behaviors in mirror mode, but usually just watched when played back the same material. Mirror mode behavior was also compared to interacting with real dolphins (controls). Mark tests were conducted, as well as switches from front to side self-views to see if the dolphins turned. They presented marked areas to the self-view television and turned. The results suggest self-examination over social behavior.

Title The experience of self in the bottlenose dolphin Type Journal Article
Year 1995 Publication Consciousness and Cognition Abbreviated Journal Conscious Cogn
Volume 4 Issue 2 Pages 244-247
Keywords (up) Animal Communication; Animals; *Awareness; Body Image; Dolphins/*psychology; Female; Humans; Male; *Self Concept; Social Behavior; Species Specificity; *Television; *Visual Perception
Abstract Marten and Psarakos have presented some evidence which suggests that objective self-awareness and possibly representations of self may characterize the dolphins' experience of self. Their research demonstrates the possibility of similarities in the sense of self between primate species and dolphins, although whether dolphins have subjective self-awareness, personal memories, and theories of self--all important facets of the sense of self in humans--was not examined. Clearly, even this limited evidence was difficult to achieve; the difficulties in adapting methods and coding behavior are quite apparent in their report. Future progress, however, may depend upon clarification of what are the necessary components for a sense of self and an explication of how these might be reflected in dolphin behavior. We are mindful of the authors' point (pp. 219 and 220) that the dolphin lives more in an acoustic than a visual environment. Thus, while tasks relying upon vision may reveal the presence or absence of the sense of self in primates, it might well be the case that in dolphins self-related experiences might be better revealed in auditory tasks. But then, what is the nature of human self-awareness in terms of audition? While both conceptual and methodological hurdles remain, Marten and Psarakos have demonstrated that important questions can be asked about the minds and phenomenal worlds of nonanthropoid species.

Title The prevalence of abnormal behaviours in dressage, eventing and endurance horses in relation to stabling Type Journal Article
Year 1995 Publication The Veterinary record Abbreviated Journal Vet. Rec.
Volume 137 Issue 2 Pages 36-37
Keywords (up) Animal Husbandry/*methods; Animals; *Behavior, Animal; Horse Diseases/*psychology; Horses; *Physical Conditioning, Animal; Prevalence; Questionnaires; *Stereotyped Behavior
Abstract The behaviour of horses competing in different disciplines was studied and the relationship between the time they spent out of the stable and the prevalence of abnormal behaviour was examined. The owners of dressage, eventing and endurance horses were sent a questionnaire and a total of 1101 responses were received, giving data on 1750 horses. The behaviours studied were wood-chewing, weaving, crib-biting/wind-sucking and box-walking. The reported percentage prevalences of abnormal behaviour for the dressage, eventing and endurance horses were 32.5, 30.8 and 19.5, respectively. The relationship between the time spent in the stable and the prevalence of abnormal behaviour was examined by chi 2 tests which showed that there were significant linear trends for the eventing group (P < 0.001) and the dressage group (P < 0.05). It is concluded that the time a horse spends out of the stable is related to the discipline for which it is being trained and in dressage and eventing horses the time spent in a stable is correlated with an increased risk of abnormal behaviour.

Title Management factors associated with stereotypic and redirected behaviour in the thoroughbred horse Type Journal Article
Year 1995 Publication Equine veterinary journal Abbreviated Journal Equine Vet J
Volume 27 Issue 2 Pages 86-91
Keywords (up) Animal Husbandry/*methods; Animals; Horse Diseases/psychology/*therapy; Horses; Risk Factors; *Stereotyped Behavior; Time Factors
Abstract A greater knowledge of the effect of management factors is required to investigate the ontogeny of abnormal behaviour in the stabled horse. A postal survey of racehorse (flat) trainers yielded information about 22 yard and management factors. The relationship of the factors to the prevalence of abnormal behaviour was analysed by logistic regression. Management factors related to the time spent in the stable showed the strongest associations with stereotypic behaviour. The risk of horses performing abnormal behaviour increased: 1) as the amount of forage fell below 6.8 kg/day, 2) when bedding types other than straw were used, 3) when the total number of horses on the yard was fewer than 75, 4) in association with box designs that minimised contact between neighbouring horses, 5) when hay, rather than other types of forage, was used.

Title Farm animal well-being and intensive production systems Type Journal Article
Year 1995 Publication Journal of Animal Science Abbreviated Journal J. Anim Sci.
Volume 73 Issue 9 Pages 2744-2751
Keywords (up) Animal Husbandry/legislation & jurisprudence/*standards; Animal Rights/legislation & jurisprudence/standards; Animal Welfare/legislation & jurisprudence/*standards; Animals; Animals, Domestic/*growth & development/*physiology; Breeding/legislation & jurisprudence/*standards; Cattle; Chickens; Environment; Reproduction/physiology; Sheep; Swine
Abstract Animal welfare, or well-being, is a social issue with ethical, scientific, political, and aesthetic properties. Answering questions about the welfare of animals requires scientific definition, assessment, solutions, and public acceptance. With respect to the actual well-being of the animal, most issues are centered on how the animal “feels” when managed within a specific level of confinement, during special agricultural practices (e.g., tail docking, beak trimming, etc.) and handling. Questions of this nature may require exploration of animal cognition, motivation, perception, and emotional states in addition to more commonly recognized indicators of well-being. Several general approaches have emerged for solving problems concerning animal well-being in intensive production systems: environmental, genetic, and therapeutic. Environmental approaches involve modifying existing systems to accommodate specific welfare concerns or development of alternative systems. Genetic approaches involve changing the behavioral and (or) physiological nature of the animal to reduce or eliminate behaviors that are undesirable within intensive system. Therapeutic approaches of a physical (tail docking, beak trimming) and physiological (drug and nutritional therapy) nature bring both concern and promise with regard to the reduction of confinement stress. Finally, the recent focus on commodity quality assurance programs may indirectly provide benefits for animal well-being. Although research in the area of animal well-being will provide important information for better animal management, handling, care, and the physical design of intensive production systems there is still some uncertainty regarding public acceptance. The aesthetics of modern intensive production systems may have as much to do with public acceptance as with science.

Title Salivary IgA: a Possible Stress Marker In Dogs Type Abstract
Year 1995 Publication Animal Welfare Abbreviated Journal
Volume 4 Issue 4 Pages 339-350
Keywords (up) Animal Welfare; Behaviour; Cortisol; Dog; Salivary Iga (S-Iga); Stress; Well-Being
Abstract Stress in humans has been reported to be associated with a decrease in the salivary immunoglobulin A (s-IgA) levels enabling the possible use of s-IgA to assess stress. Prolonged stress, if reliably assessed in a non-invasive manner, may be used to assess animal welfare. This study analysed groups of dogs undergoing physical and temperamental training and s-IgA levels were measured by rocket immunoelectrophoresis in prospective samples. Behavioural assessment was carried out and cortisol levels in saliva were measured by ELISA. A significant negative correlation (P < 0.007) between the logarithmic cortisol concentrations and s-IgA levels in saliva was recorded. The behavioural assessment of the dogs agreed well with the biochemical markers. It is concluded that IgA levels in saliva may be a useful marker of dog well-being and that stress results in decreased s-IgA levels.

Title Most directed forgetting in pigeons can be attributed to the absence of reinforcement on forget trials during training or to other procedural artifacts Type Journal Article
Year 1995 Publication Journal of the experimental analysis of behavior Abbreviated Journal J Exp Anal Behav
Volume 63 Issue 2 Pages 127-137
Keywords (up) Animals; *Attention; Color Perception; Columbidae; Cues; *Discrimination Learning; *Mental Recall; Motivation; Pattern Recognition, Visual; *Reinforcement Schedule; Retention (Psychology)
Abstract In research on directed forgetting in pigeons using delayed matching procedures, remember cues, presented in the delay interval between sample and comparisons, have been followed by comparisons (i.e., a memory test), whereas forget cues have been followed by one of a number of different sample-independent events. The source of directed forgetting in delayed matching to sample in pigeons was examined in a 2 x 2 design by independently manipulating whether or not forget-cue trials in training ended with reinforcement and whether or not forget-cue trials in training included a simultaneous discrimination (involving stimuli other than those used in the matching task). Results were consistent with the hypothesis that reinforced responding following forget cues is sufficient to eliminate performance deficits on forget-cue probe trials. Only when reinforcement was omitted on forget-cue trials in training (whether a discrimination was required or not) was there a decrement in accuracy on forget-cue probe trials. When reinforcement is present, however, the pattern of responding established during and following a forget cue in training may also play a role in the directed forgetting effect. These findings support the view that much of the evidence for directed forgetting using matching procedures may result from motivational and behavioral artifacts rather than the loss of memory.
