  • Bell, Heather C.; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Dept. of NeuroscienceArts and ScienceDepartment of Neuroscience, 2013)
    Many types of animal behaviour, especially seemingly complex social interactions, have been attributed to the existence of complex cognitive mechanisms, underpinned by stimulus-response (S-R) rules. Indeed, as speci c ...
  • Reinhart, Christine J.; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2008Arts and ScienceNeuroscience, 2008)
    Macaques (Macaca) are the most geographically widespread and behaviourally diverse primate genus, and although macaque species share the same basic social structure, they display broad interspecific variation in patterns ...
  • Himmler, Brett T.; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Dept. of Neuroscience, 2011Arts and ScienceDepartment of Neuroscience, 2011)
    The influence of play behavior on the brain was investigated through plasticity and metaplasticity methodology. Regions in both cortical and sub-cortical areas were investigated. Animals in both studies either experienced ...
  • Iwaniuk, Andrew N.; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2000Arts and ScienceDepartment of Pyschology, 2000)
    Emancipating the forelimbs from locomotion for use in other activities, such as food manipulation, is a major evolutionary milestone. A variety of selective forces and evolutionary correlates may influence the evolution ...
  • Himmler, Brett T.; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Dept. of NeuroscienceArts and ScienceDepartment of Neuroscience, 2015)
    In laboratory rats, juvenile play behavior has been shown to influence the development of the medial prefrontal cortex (mPFC) and the experience of interacting with multiple partners has been shown to influence the orbital ...
  • Cooper, Stephanie A.; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2005Arts and ScienceDepartment of Neuroscience, 2005)
    Changes in postural stability following sensory manipulation were investigated among Parkinson's disease patients and healthy older adults. Sixteen Parkinson's disease patients (PD; mean age 68.2 + 2.7 years) and sixteen ...
  • Reinhart, Christine J.; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2005Arts and ScienceDepartment of Neuroscience, 2005)
    Play fighting in kindling-prone (FAST) and kindling-resistant (SLOW) rats: Potential genetic controls over the components of play. Even though the behavioral components of play fighting have been well characterized in the ...
  • Bell, Heather C.; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2008Arts and ScienceNeuroscience, 2008)
    The prefrontal cortex (PFC) has long been thought to be the seat of social behaviours in mammals. Lesions of the orbitofrontal cortex (OFC), a subregion of the PFC, are known to cause social deficits in humans. Interestingly, ...
  • Foroud, Afra; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2002Arts and ScienceDepartment of Neuroscience, 2002)
    Playing with Play: Movement and experience in the development of play fighting in rats. Juvenile rats are more gentle in the way they play fight than are adult rats. I used Laban Movement Analysis (LMA), a form of movement ...
  • Janz, Linda; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 1997Management, 1997)
    This study examined results of a World Wide Web survey that used the framework of domain theory of moral development to examine attitudes of Internet users assuming perspectives of victims, aggressors and bystanders toward ...
  • Smith, Lori K.; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 1996Arts and ScienceDepartment of Psychology, 1996)
    Playing is a common behavior among juveniles of many mammalian species, including rats (Rattus norvegicus). The mechanisms underlying the change that occurs in the play fighting of male rats at puberty were the focus of ...
  • Kisko, Theresa M. (Lethbridge, Alta. : University of Lethbridge, Dept. of Neuroscience.Arts and ScienceDepartment of Neuroscience, 2014-10-03)
    The role of 50 kHz ultrasonic vocalizations as play signals was examined, in this thesis by investigating the effects of devocalization on playful interactions in both juveniles and adults. In both studies, the animals ...
  • Field, Evelyn F.; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 1996Arts and ScienceDepartment of Psychology, 1996)
    The role of sex in the organization of movement is not commonly addressed in the literature. The objective of this thesis was to determine whether differences exist between males and females in the way they organize their ...
  • Field, Evelyn F.; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2006Arts and ScienceDepartment of Neuroscience, 2006)
    Whether there are sex differences in the kinematic organization of non-reproductive behaviors is rarely addressed. In this thesis, evidence is presented that male and female rats organize their posture and stepping ...
  • Arelis, Cheryl L.; University of Lethbridge. Faculty of Arts and Science (Lethbridge, Alta. : University of Lethbridge, Faculty of Arts and Science, 2006Arts and ScienceDepartment of Neuroscience, 2006)
    Stress is thought to be antithetical to play. However, this thesis shows that mild stress (e.g., social deprivation) enhances rough-and-tumble play, as opposed to other social behaviors, in adolescent rats. Social deprivation ...
  • Himmler, Stephanie M. (Lethbridge, Alta. : University of Lethbridge, Dept. of NeuroscienceArts and ScienceDepartment of Neuroscience, 2015)
    Play fighting has been proposed to provide animals with experiences that promote behavioural flexibility, which helps them to successfully navigate their physical and social environments later on in life. However, there ...
