The Human Intruder Test: An Anxiety Assessment In Rhesus Macaques (Macaca Mulatta), Emily J. Peterson
The Human Intruder Test: An Anxiety Assessment In Rhesus Macaques (Macaca Mulatta), Emily J. Peterson
Masters Theses
The human intruder test (HIT) is a noninvasive tool widely used for assessing anxiety in rhesus macaques (Macaca mulatta). This thesis explores the HIT procedure and applies it to a population of monkeys with a self-injurious behavioral pathology. Individual variation on this test can be used to assess anxiety and temperament. The first experiment of this thesis applied two different procedures of the HIT to 17 monkeys at UMass. Monkeys displayed little response to the intruder, and no significant differences were detected for the two procedures. To determine whether these responses were unique to the UMass monkeys, their …
Associations Between Anxiety And Attention In Laboratory-Housed Rhesus Macaques (Macaca Mulatta), Lauren E. Hobbs
Associations Between Anxiety And Attention In Laboratory-Housed Rhesus Macaques (Macaca Mulatta), Lauren E. Hobbs
Masters Theses
Previous studies completed with humans have revealed insight into the effects of anxiety on attention tasks such the dot-probe task, but there is little information about such effects on non-human primates. This study aimed to assess whether anxiety or anxious behaviors would impact rhesus macaque performance on a three stimuli paradigm similar to the dot-probe task. Utilizing images of conspecifics (strong threat, mild threat, and neutral), eight monkeys were video recorded completing a task that required them to slide two doors, which held these images, to the side to obtain a treat. We hypothesized that behavioral phenotype (high or low …
The Effects Of Construction Activity On The Behavior Of Captive Rhesus Monkeys (Macaca Mulatta), Courtney A. Begnoche
The Effects Of Construction Activity On The Behavior Of Captive Rhesus Monkeys (Macaca Mulatta), Courtney A. Begnoche
Masters Theses 1911 - February 2014
Previous studies have revealed insight into the effects of noises and vibrations on rodents, livestock, and zoo animals, but there is little information about such effects on non-human primates. This study aimed to assess the impact of construction activity on the behavior of animals in a non-human primate (rhesus macaque) facility. Construction activity and modified frequency behavioral data were divided into three phases: baseline (~3 months prior to construction), roof (construction on top of the animal facility), and honors (construction of 7 new buildings adjacent to the facility). We hypothesized that anxiety behaviors (scratch and yawn) would be increased during …
