  1. Pavlovian conditioning enhances resistance to disruption of dogs performing an odor discrimination

    Contributor(s):: Hall, Nathaniel J., Smith, David W., Wynne, Clive D. L.

  2. Does temperament affect learning in calves?

    Contributor(s):: Webb, L. E., Reenen, C. G. van, Jensen, M. B., Schmitt, O., Bokkers, E. A. M.

    The aim of the study was to investigate how temperament affects learning ability in calves. Nine two-month-old Holstein-Friesian bull calves were subjected to four challenge tests: novel object (NOT), novel environment (NET), social isolation (SIT), and social isolation with a novel environmental...

  3. Effect of odor preexposure on acquisition of an odor discrimination in dogs

    Contributor(s):: Nathan Hall, David Smith, Clive Wynne

    In two experiments we investigated the impact of odor pre-exposure treatments on the acquisition of an olfactory discrimination in dogs. In the first experiment four groups of dogs were each given five days odor-exposure treatment prior to discrimination training. Dogs in the exposure group were...

  4. Key considerations for the experimental training and evaluation of cancer odour detection dogs: lessons learnt from a double-blind, controlled trial of prostate cancer detection

    Contributor(s):: Elliker, K. R., Sommerville, B. A., Broom, D. M., Neal, D. E., Armstrong, S., Williams, H. C.

  5. Olfactory detection of prostate cancer by dogs sniffing urine: a step forward in early diagnosis

    Contributor(s):: Cornu, J. N., Cancel-Tassin, G., Ondet, V., Girardet, C., Cussenot, O.

  6. Prostate cancer: eNose--man's new best friend?

    Contributor(s):: Phillips, R.

  7. A conditioned response overrides social attraction in common carp: a possibility for low stress sorting strongly schooling fish?

    Contributor(s):: Mesquita, F. O., Borcato, F. L., Huntingford, F. A.

    In this study we investigated whether a conditioned response to a light cue can override the strong schooling tendency of common carp, with a view to identifying a possible system for low stress control of movement for captive fish. Carp were trained in groups of three to approach and bite a...

  8. Conditioned taste aversion in the grey fox ( Pseudalopex griseus), in Southern Argentine Patagonia

    Contributor(s):: Nielsen, S., Travaini, A., Vassallo, A. I., Procopio, D., Zapata, S. C.

    Attempts to control cougar ( Puma concolor) and culpeo fox ( Pseudalopex culpaeus) populations in Patagonia through poisoning, negatively affects grey foxes ( Pseudalopex griseus) and many other non-target species. It is therefore advisable to develop selective predator control methods. Among a...

  9. Persistency of the piglet's reactivity to the handler following a previous positive or negative experience

    Contributor(s):: Brajon, S., Laforest, J. P., Bergeron, R., Tallet, C., Hotzel, M. J., Devillers, N.

    A central question in the stockman-animal relationship is how animals perceive humans depending on previous interactions with them. This study aimed at measuring the influence of a previous experience with humans on subsequent reactivity to humans of weaned piglets. Treatments differing in type...

  10. Impact of individual training parameters and manner of taking breath odor samples on the reliability of canines as cancer screeners

    Contributor(s):: Walczak, M., Jezierski, T., Gorecka-Bruzda, A., Sobczynska, M., Ensminger, J.

  11. Operant conditioning parameters in cancer detection dogs.

    Contributor(s):: Walczak, M., Jezierski, T., Gorecka-Bruzda, A., Adamkiewicz, E.

  12. To jump or not to jump? Strategies employed by leisure and sport horses

    Contributor(s):: Gorecka-Bruzda, A., Jastrzebska, E., Muszynska, A., Jedrzejewska, E., Jaworski, Z., Jezierski, T., Murphy, J.

  13. A case study employing operant conditioning to reduce stress of capture for red-bellied tamarins ( Saguinus labiatus )

    Contributor(s):: Owen, Y., Amory, J. R.

    Traditional techniques used to capture New World monkeys, such as net capture, can induce high levels of acute stress detrimental to welfare. Alternatively, training nonhuman animals via operant conditioning to voluntarily participate in husbandry and/or veterinary practices is accepted as a...

  14. Positive reinforcement training for a trunk wash in Nepal's working elephants: demonstrating alternatives to traditional elephant training techniques

    Contributor(s):: Fagen, A., Narayan, Acharya, Kaufman, G. E.

    Many trainers of animals in the zoo now rely on positive reinforcement training to teach animals to voluntarily participate in husbandry and veterinary procedures in an effort to improve behavioral reliability, captive management, and welfare. However, captive elephant handlers in Nepal still...

  15. Systematic investigation of the stability of food preferences in captive orangutans: implications for positive reinforcement training

    Contributor(s):: Clay, A. W., Bloomsmith, M. A., Marr, M. J., Maple, T. L.

    Using preference-assessment tests with humans in conjunction with behavioral modification sessions has been a regular component of almost all operant conditioning programs with mentally challenged humans. This has been very effective in improving the efficiency of behavioral training in these...

  16. The development of an operant conditioning training program for New World primates at the Bronx Zoo. (Training Nonhuman Primates Using Positive Reinforcement Techniques)

    Contributor(s):: Savastano, G., Hanson, A., McCann, C.

    This article described the development of an operant conditioning training programme for 17 species of New World primates at the Bronx Zoo, New York, USA. To apply less invasive techniques to husbandry protocols, the study introduced behaviours such as hand feeding, syringe feeding, targeting,...

  17. The effects of environmental control on cognition in rats ( Rattus norvegicus )

    Contributor(s):: Alliger, A. A., Moller, P.

    The aim of this study was to allow nonhuman animals to control their environment using operant conditioning procedures and to assess the effect of control on cognitive tasks. The study tested 4 predictions: (a) rats (Rattus norvegicus) will control a light stimulus; (b) animals will exhibit...

  18. The effects of husbandry training on stereotypic pacing in captive African wild dogs ( Lycaon pictus )

    Contributor(s):: Shyne, A., Block, M.

    To examine the effects of operant conditioning on stereotypic pacing in 3 female African wild dogs located at the Franklin Park Zoo in Boston, this study made recordings of pacing behavior immediately following individual sessions of husbandry training and 2 no-training conditions. The study...

  19. The use of classical and operant conditioning in training Aldabra tortoises ( Geochelone gigantea ) for venipuncture and other husbandry issues

    Contributor(s):: Weiss, E., Wilson, S.

    A variety of nonhuman animals in zoo and research settings have been the subjects of classical and operant conditioning techniques. Much of the published work has focused on mammals, husbandry training and veterinary issues. However, several zoos are training reptiles and birds for similar...

    Contributor(s):: Marranzino, A.

    Positive reinforcement training (PRT) was used on 4 adult zebra sharks, Stegostoma fasciatum, housed at the Downtown Aquarium, Denver, to determine the ability of zebra sharks to become desensitized to various stimuli associated with veterinary procedures. One male and 3 female sharks were...
