| Title | Relationships between patterns of Fecal corticoid excretion and behavior, reproduction, and environmental factors in captive black (Diceros bicornis) and white (Ceratotherium simum) rhinoceros | Type | Journal Article | ||

| Abstract | Mortality is high in zoo-housed black rhinoceros (Diceros bicornis), and the reproductive rates of captive white rhinoceros (Ceratotherium simum) are unsustainably low. To determine the possible role of stress in the causation of these problems, we analyzed weekly fecal samples collected for 1 year from black (10 males and 16 females) and white (six males and 13 females) rhinoceroses at 16 zoos for corticoid metabolite concentrations. Fecal corticoid profiles were examined in relation to behavior as rated by keepers in a questionnaire, luteal phase ovarian cycles of females (Brown et al., 2001), and socioenvironmental factors. We compared individual fecal corticoid profiles by examining hormone means and variability (i.e., standard deviation (SD) and coefficient of variation (CV)). For the black rhinos, higher mean corticoid concentrations were found at zoos where rhinos were maintained in enclosures that were exposed to the public around a greater portion of the perimeter. Higher variability in corticoid excretion was correlated with higher rates of fighting between breeding partners and higher institutional mortality rates. Black rhino pairs that were kept separated exhibited lower corticoid variability and less fighting activity when they were introduced during female estrous periods compared to pairs that were kept together every day. For white rhinos, significantly lower mean corticoids were found for individuals that rated higher on “friendliness to keeper.” Higher corticoid variability was found in noncycling as compared to cycling white rhino females. Noncycling females exhibited higher rates of stereotypic pacing and lower frequencies of olfactory behaviors. Interindividual differences in mean corticoids in both species appeared to be related to responsiveness to humans, whereas corticoid variability was related to intraspecific social relationships. More importantly, high corticoid variability appeared to be an indicator of chronic or “bad” stress, because of its association with potentially deleterious consequences in each species (i.e., fighting and mortality (black rhino), and reproductive acyclicity (white rhino)). Our results provide evidence that social stressors may cause chronic stress in black and white rhinos, and that this contributes to the captive-population sustainability problems observed in each species.

| Title | The Revolution in Horsemanship: And What It Means to Mankind | Type | Book Whole | ||
| Year | 2005 | Publication | Abbreviated Journal | ||
| Volume | Issue | Pages | |||
| Keywords | |||||
| Abstract | Synopsis Beginning with equine evolution and domestication, Dr. Miller and Rick Lamb focus on the contributions of such classical horsemen as Xenophon, Pluvinel, nineteenth-century “whisperers, tamers, and professors,” and modern masters like the Dorrances, Buck Brannaman, Pat Parelli, John Lyons, and their disciples, and the connection between rodeo and natural horsemanship. The authors describe how the horse's mind works, how horses learn, and how the revolution has used those principles, especially with regard to a training regimen for newborn foals developed by Dr. Miller that produces positive results to last a lifetime. These training methods include new techniques in riding, such as preliminary groundwork and the independent seat, as well as visualization and other aspects of sport psychology, yoga, and allied disciplines. Appendices assess innovations in hoof care, nutrition, and veterinary treatment, including so-called “alternative therapies.” |

| Title | Complex problem-solving: a field in search of a definition? | Type | Journal Article | ||

| Abstract | Complex problem-solving (CPS) is as an area of cognitive science that has received a good amount of attention, but theories in the field have not progressed accordingly. The reasons could be the lack of good definitions and classifications of the tasks (taxonomies). Although complexity is a term used pervasively in psychology and is operationalized in different ways, there are no psychological theories of complexity. The definition of problem-solving has been changed in the past to reflect the varied interests of the researchers and has lost its initial concreteness. These two facts together make it difficult to define CPS or make clear if CPS should reuse the theory and methods of classical problem-solving or on the contrary should build a theoretical structure starting from scratch. A taxonomy is offered of tasks using both formal features and psychological features that are theory-independent that could help compare the CPS tasks used in the literature. The adequateness is also reviewed of the most extended definitions of CPS and conclude that they are in serious need of review, since they cover tasks that are not considered problem-solving by their own authors or are not complex, but ignore others that should clearly be included. | ||||

| Volume | Issue | Pages | |||
| Keywords | |||||
| Abstract | Although this bookis focusedon the cognitive neuroscience ofhuman social behaviour, an understandingofsocial cognition in non-human animals is critical for unravellingthe neural basis of social cognition in humans as well as the selective pressures that have shapedthe evolution ofcomplex social cognition. Thanks to methodological limitations, we know little about the relationships between certain biochemical andelectrophysiological properties ofthe human brain andhow theycompute the behaviour andmental states ofother individuals. Traditional techniques for examiningneural function in humans, such as event-relatedpotentials (ERP),positron emission tomography(PET),and functional magnetic resonance imaging(fMRI),are constrainedbythe fact that subjects are placed either into an immoveable scanner with a lot ofbackgroundnoise or wiredup with dozens of electrodes that are sensitive to slight movements. The possibilityofscanningor recordingbrain waves from two individuals that are physicallyinteractingsociallyis technicallyimpossible at present (however, see Montague et al, 2002 for a new methodfor simultaneouslyscanningtwo individuals interactingvia a computer). The onlywayto understandthe neurocognitive architecture ofhuman social behaviour is to examine similar social processes in both human andnon-human animal minds andmake comparisons at the species level. An additional argument is that traditional human socio-cognitive tasks are dependent on the use ofstories, cartoons andverbal cues andinstructions (Heberlein & Adolphs, this volume)which themselves will elicit specific neural responses that have to be eliminatedfrom neural responses specificallyrelatedto mindreading. Therefore, the development ofnon-verbal tasks wouldprovide a breakthrough for studies in non-linguistic animals, pre-verbal human infants andhuman cognitive neuroimaging. |

| Abstract | Context: It is argued in self-determination theory that the motivation underlying behavior has implications for health and well-being independent of the behavior itself. Objective: To examine associations between athlete motivations for returning to sport after injury and perceived psychological return-to-sport outcomes. Design: A correlational survey design was employed to obtain data in Canada, Australia, and England. Participants: Elite and subelite athletes (N = 180) with injuries requiring a minimum 2-month absence from sport participation. Main Outcome Measures: Participants completed an inventory measuring perceptions of motivation to return to sport from a serious injury and psychological return-to-sport outcomes. Results: Correlational analyses revealed that intrinsic motivations for returning to competition were associated with a positive renewed perspective on sport participation. Conversely, extrinsic motivations for returning to sport were associated with increased worry and concern. Conclusions: The motivation underlying return to sport might play an important role in return-to-sport perceptions among elite and subelite athletes. | ||||

| Abstract | The purpose of this study was to investigate the response of horses to confinement and isolation in a stable (indoor individual housing) for the first time using behavioral indices, heart rate, and salivary cortisol concentration. Six naive 2-year-old Australian Stock Horse fillies were examined at 4-hour intervals over 24 hours in an outdoor group paddock followed by 24 hours in indoor individual housing. Behavioral observations and scores and heart rates were recorded and saliva samples were taken at each interval. During stabling, all horses became agitated and demonstrated increased vocalization and movement. Behavioral scores were significantly higher in the indoor individual housing (P < .001). No significant difference in heart rates between the two environments was detected. Mean salivary cortisol did not increase significantly (2 ng/mL ± 1.4 ng/mL in outdoor group paddock vs 2.5 mL ± 1.2 ng/mL in indoor individual housing). No diurnal rhythm in salivary cortisol was evident in either the outdoor group paddock or indoor individual housing. The results of this study highlight that a combination of behavioral and physiological measures allow better understanding of stress, where one measurement may be misleading. First time stabling of horses elicited marked behavioral responses indicative of stress that were not reflected in increased heart rates or salivary cortisol concentrations. The lack of a diurnal cortisol rhythm and the comparatively high basal cortisol concentrations found in the outdoor group paddock environment may imply that the fillies were already stressed; therefore, stabling did not cause further aberrations detectable by salivary cortisol analysis. | ||||

| Abstract | This study was designed to develop reliable methods for quantification of cortisol and cortisol immunoreactive metabolites (C-CIM) and immunoglobulin A (IgA) in reindeer serum, saliva, urine, and feces as tools for the objective noninvasive assessment of well-being and immunocompetence in reindeer. Although C-CIM was readily quantifiable by radioimmunoassay in serum, urine, and feces, the levels in saliva samples were low, rendering quantification unreliable. Whereas IgA concentrations were high in feces samples, they were much lower, albeit quantifiable, in serum and urine; the levels in saliva samples were too low for quantification with the use of an enzyme-linked immunosorbent assay that we developed. Further studies are in progress to validate the usefulness of fecal levels of C-CIM and IgA in the assessment of welfare in reindeer. | ||||
