The Use Of Personality Assessments In Designing Environmental Enrichment For Garnett's Bushbabies (Otolemur Garnettii), Lauren Elizabeth Highfill
The Use Of Personality Assessments In Designing Environmental Enrichment For Garnett's Bushbabies (Otolemur Garnettii), Lauren Elizabeth Highfill
Dissertations
Recently the study of animal personality has become an important and credible topic of research and a number of studies have revealed personality traits in a variety of species. The consideration of individual animal personality traits is important for animal management and welfare. For example, ensuring inter-individual compatibility in group housing animals may serve to ensure the safety of the whole group. To date, no formal research has been conducted on whether the assessment of individual personality traits could be used as a tool for individualizing environmental enrichment interventions. The goal of environmental enrichment is to increase the rate of …
The Influence Of Species And Context On Human-Dolphin Interactions, Deirdre Breen Yeater
The Influence Of Species And Context On Human-Dolphin Interactions, Deirdre Breen Yeater
Dissertations
Anthropogenic activities pose a threat to marine mammals around the world. Cetaceans that use coastal waters are at particular risk for potential disturbances caused by vessel traffic and human swimmers. Although many cetacean species are found near the coast of Utila, Honduras, little is known about their behavior or the effects of anthropogenic activities on their behavior. Whether the presence of boats and human swimmers led to short-term changes in dolphin behavior was investigated for three commonly sighted species of dolphins; rough-toothed (Steno bredanensis), spinner (Stenalla longirostris), and bottlenose (Turslops truncatus). The dolphins' behavioral activities, with and without other boats …
Affective Flexibility: Evaluative Processing Goals Shape Amygdala Activity, William A. Cunningham, Jay J. Van Bavel, Ingrid Johnsen Haas
Affective Flexibility: Evaluative Processing Goals Shape Amygdala Activity, William A. Cunningham, Jay J. Van Bavel, Ingrid Johnsen Haas
Department of Political Science: Faculty Publications
Although early research implicated the amygdala in automatic processing of negative information, more recent research suggests that it plays a more general role in processing the motivational relevance of various stimuli, suggesting that the relation between valence and amygdala activation may depend on contextual goals. This study provides experimental evidence that the relation between valence and amygdala activity is dynamically modulated by evaluative goals. During functional magnetic resonance imaging, participants evaluated the positive, negative, or overall (positive plus negative) aspects of famous people. When participants were providing overall evaluations, both positive and negative names were associated with amygdala activation. When …
Electromagnetic Differences In The Brain During Memory Retrieval, Warren Scott Merrifield
Electromagnetic Differences In The Brain During Memory Retrieval, Warren Scott Merrifield
Loma Linda University Electronic Theses, Dissertations & Projects
The primary objectives for this experiment were to analyze the neuroanatomical correlates of autobiographical, episodic and semantic memory, use a different paradigm to promote episodic memory retrieval, and employ a different analysis technique to understand retrieval processes. Autobiographical and episodic memories are personal memories from the past. Autobiographical is more general (e.g. a street name of a house growing up) and episodic is more specific to time (e.g. 13th birthday party that took place on a street). For autobiographical and episodic memory retrieval operations, there is no general consensus as to the localization of function, but bilateral activation of the …
The Influence Of College Students’ Perception Of Parental (Or Primary Caregiver) Expectations On Coping Behavior And Adjustment In Early Adulthood, Jessica Smith
Theses, Dissertations and Capstones
While some research has examined how parental expectations affect educational achievement, there is very little known about how parental expectations affect the development of coping skills and adaptive and maladaptive psychosocial functions. Participants were asked to complete a measure of their abilities in academics, sports, leadership, honesty, responsibilities, among other things. Then, they completed a measure of what they perceived their parents’ expectations of those areas were. Lastly, they completed the Behavioral Assessment System for Children-College Self Report of Personality form as a measure of adaptive and maladaptive functioning. The goals of this study are to investigate 1) if participants' …
Temperament And Character Correlates Of The Startle Reflex, Kristen Lee Godenick
Temperament And Character Correlates Of The Startle Reflex, Kristen Lee Godenick
Loma Linda University Electronic Theses, Dissertations & Projects
Some literature suggests that individual temperament traits can modulate the startle reflex. There is evidence supporting Cloninger’s concept of Harm Avoidance as being predictive of individual differences in reactivity to aversive stimuli. (Corr, 1997). Since this finding, a new version Cloninger’s measure includes character subscales that like temperament, have been proposed to modify the meaning of experiences, changing emotional reactions. High scorers on the character variables are less susceptible to excessive anxiety and tend to have neurochemical profiles that are not consistent with anxiety disorders (Gillespie, 2003; Tse & Bond, 2001; Peirson et al., 1999). It was thus hypothesized that …
The Effect Of Ethanol And Hypoglycemia On Rat Performance In The Radial Arm Maze, Monica Ann Gaffney
The Effect Of Ethanol And Hypoglycemia On Rat Performance In The Radial Arm Maze, Monica Ann Gaffney
Psychology Theses & Dissertations
Both hypoglycemia (HG) and ethanol (ETH) intoxication can cause serious impairment in physiological and psychological functioning. Their combination could cause more severe cognitive impairment than either condition alone. This experiment investigated the effects of hypoglycemia, ethanol intoxication, and their combination on rat radial arm maze performance. Eleven male rats were trained to a stable, low error rate performance in achieving food rewards in an eight arm radial arm-maze. Rats were then given either insulin (2 units/kg) or saline in combination with ETH doses of 250, 500, 1000, or 1500 mg/kg 20 minutes prior to the maze run. Treatment order was …
Effects Of Sleep Loss On Information-Processing In An Absolute Judgment Task As A Function Of Task Difficulty, Frieda O'Steen Carlton
Effects Of Sleep Loss On Information-Processing In An Absolute Judgment Task As A Function Of Task Difficulty, Frieda O'Steen Carlton
Psychology Theses & Dissertations
The effects of 36 hours of sleep loss on information-processing were assessed in an absolute judgment task. Of the 24 subjects employed, 12 served in the sleep-loss (experimental) and control conditions, respectively. All subjects were tested individually for a total of ten sessions; the control group was tested on ten consecutive days, whereas the experimental subjects were tested every four hours over a 36-hour period of sleep loss, and at a recovery session following approximately 12 hours of rest and recovery. The task required subjects to make absolute judgments of the size of two small circles of light and to …
Exteroceptive Influence On A Marihuana Induced Conditioned Taste Aversion, Albert William Greenwood
Exteroceptive Influence On A Marihuana Induced Conditioned Taste Aversion, Albert William Greenwood
Dissertations and Theses
Forty-five male, Sprague Dawley rats were used to determine if external stimuli could influence the length of a conditioned taste aversion. Animals were given a novel taste (sucrose), and then injected with one of three different substances, marihuana, LiCI, or saline. The animals were then placed into either a stimulation condition, a non-stimulation condition, or returned to the home cage. The stimulation condition contained aversive stimuli in the form of bright, flashing lights and loud noises. The other conditions had no aversive stimulation. It was expected that the animals receiving injections of marihuana would have an increase in their responsiveness …
The Effects Of Electroconvulsive Shock Following Different Noncontingent Foot Shock Durations On A Conditioned Emotional Response, Carol Knobel
All Master's Theses
Varied lengths of noncontingent foot shock (NCFS) followed by an ECS or NO ECS were presented 24 hours after fear conditioning to investigate the state dependency hypothesis. The hypothesis that the NCFS would interact with ECS to produce a transient attenuation of fear conditioning was not supported. Results were discussed in terms of the possibility that the state dependency hypothesis applies only to certain levels of brain excitation when NCFS and ECS are used to induce brain state changes.
