    | Contributor(s):: Gottlieb, D. H., Maier, A., Coleman, K.

    Full body repetitive behaviors, known as motor stereotypic behaviors (MSBs), are one of the most commonly seen abnormal behaviors in captive non-human primates, and are frequently used as a behavioral measure of well-being. The main goal of this paper was to examine the role of environmental...

  7. Effects of visual contact with zoo visitors on black-capped capuchin welfare

    | Contributor(s):: Sherwen, S. L., Harvey, T. J., Magrath, M. J. L., Butler, K. L., Fanson, K. V., Hemsworth, P. H.

    Previous research has suggested that the presence of zoo visitors may be stressful for various primate species, and visual contact with visitors may be the sensory stimuli that mediate visitor effects. We studied a group of black-capped capuchins, Cebus apella, in a controlled experiment,...

  8. Left gaze bias in humans, rhesus monkeys and domestic dogs

    | Contributor(s):: Kun Guo, Daniel Mills, Kerstin Meints, Charlotte Hall, Sophie Hall

    While viewing faces, human adults often demonstrate a natural gaze bias towards the left visual field, that is, the right side of the viewee’s face is often inspected first and for longer periods. Using a preferential looking paradigm, we demonstrate that this bias is neither uniquely human...

  9. Social housing of non-human primates in a research facility: socialisation across macaque species and sexes

    | Contributor(s):: Rehrig, A., DiVincenti, L., Jr., Schery, L. A.

    Refinement of social housing practices is paramount to improving animal welfare in laboratory environments, especially with regard to non-human primates. Even though social housing of the same species should be considered the optimal paradigm, cynomolgus ( Macaca fascicularis) and rhesus macaques...

  10. Positive reinforcement training moderates only high levels of abnormal behavior in singly housed rhesus macaques

    | Contributor(s):: Baker, K. C., Bloomsmith, M., Neu, K., Griffis, C., Maloney, M., Oettinger, B., Schoof, V. A. M., Martinez, M.

    This study evaluated the application of positive reinforcement training (PRT) as an intervention for abnormal behaviors in singly housed laboratory rhesus macaques at 2 large primate facilities. Training involved basic control behaviors and body-part presentation. The study compared baseline...

  11. Effects of training on stress-related behavior of the common marmoset ( Callithrix jacchus ) in relation to coping with routine husbandry procedures. (Training Nonhuman Primates Using Positive Reinforcement Techniques)

    | Contributor(s):: Bassett, L., Buchanan-Smith, H. M., McKinley, J., Smith, T. E.

    Using positive reinforcement, 12 common marmosets (Callithrix jacchus) were trained to provide urine samples on request. The marmosets were exposed to mildly stressful, routine husbandry procedures (i.e., capture and weighing). The non-human animals spent less time inactive poststressor as...

  12. Cage use and feeding height preferences of captive common marmosets ( Callithrix j. jacchus ) in two-tier cages

    | Contributor(s):: Buchanan-Smith, H. M., Shand, C., Morris, K.

    Determining appropriate feeding regimes has important welfare implications for captive primates. This study examined the preference of food bowl heights in 6 pairs of common marmosets (Callithrix jacchus) housed in a 2-tier cage system. Given that marmosets are arboreal and spend most of their...

  13. The effect of the captive environment on activity of captive cotton-top tamarins ( Saguinus oedipus )

    | Contributor(s):: Burrell, A. M., Altman, J. D.

    This study examined captive cotton-top tamarin (Saguinus oedipus) behaviour across 3 different exhibits: (a) a rain forest (30.5 m in diameter), where tamarins free-ranged with other species; (b) a caged outdoor exhibit (5 m in diameter); and (c) a caged enclosure, with access indoors (6x9 m) and...

  14. Determining the value of social companionship to captive tufted capuchin monkeys ( Cebus apella )

    | Contributor(s):: Dettmer, E., Fragaszy, D.

    The objective of the study is to assess the magnitude of the psychological need for social companionship in pair-housed tufted capuchin monkeys (Cebus apella) (six males and 1 female). The classification of commodities as necessities or luxuries are included. The study directly compared the...

Behaviours taught were target training to allow homecage weighing and providing...

  17. The myth of the aggressive monkey

    | Contributor(s):: Reinhardt, V.

    Captive rhesus macaques are not naturally aggressive, but poor husbandry and handling practices can trigger their aggression toward conspecifics and toward the human handler. The myth of the aggressive monkey probably is based on often not taking into account basic ethological principles when...

  18. Working with rather than against macaques during blood collection. (Training Nonhuman Primates Using Positive Reinforcement Techniques)

    | Contributor(s):: Reinhardt, V.

    Training macaques to cooperate during blood collection is a practicable and safe alternative to the traditional procedure implying forced restraint. It takes a cumulative total of about 1 hr to train an adult female or adult male rhesus macaque successfully to present a leg voluntarily and accept...
