The Effects Of Dolphin Education Programs On Visitors' Conservation-Related Knowledge, Attitude And Behavior, Lance Joseph Miller
The Effects Of Dolphin Education Programs On Visitors' Conservation-Related Knowledge, Attitude And Behavior, Lance Joseph Miller
Dissertations
Zoological institutions typically exhibit dolphins in educational programs such as dolphin shows and interaction programs. The goal of these programs is to entertain visitors while increasing their conservation-related knowledge, attitude and behavior towards dolphins and the marine environment. The purpose of the current study was to examine dolphin shows and interaction programs in terms of their effectiveness in meeting these goals. A multi-institutional study was conducted at six different facilities throughout the United States. A repeated measures design was used to examine the knowledge, attitude and behavior of visitors before, immediately after and three months following participation in dolphin shows …
The Effects Of Prenatal Exposure Of Valproic Acid On Cranial Nerve Nuclei: A Rat Model For An Autistic Phenotype, Shannon Pickup
The Effects Of Prenatal Exposure Of Valproic Acid On Cranial Nerve Nuclei: A Rat Model For An Autistic Phenotype, Shannon Pickup
Honors Capstone Projects - All
Autistic spectrum disorder is a term referring to five pervasive developmental disorders characterized by impairment in social interaction, deficits in verbal and non-verbal communication and stereotyped repetitive behaviors and interests. The underlying brain injury that leads to autism is also unknown. The cause is also unknown but appears to be a combination of genetic and environmental factors. A study on prenatal thalidomide exposure found patients exposure on days 20-24 of gestation lead to a 1/3 rate of autism, a huge increase from the 1/150 rate of the general population. The thalidomide data suggests the initial injury leading to autism occurs …
Does Type Of Stimulus Influence Task-Irrelevant Evaluative Categorization Processes?, Guadalupe Corral
Does Type Of Stimulus Influence Task-Irrelevant Evaluative Categorization Processes?, Guadalupe Corral
Open Access Theses & Dissertations
The effect of stimulus type on task-irrelevant evaluative categorization was examined in two separate studies by using the P3 component from event-related brain potentials. The first study presented idiosyncratic stimuli consisting of individuals that were rated by participants as either positive or negative within sequences of pictorial and verbal stimuli. The second study presented sequences of novel and familiar stimuli consisting of previously normed unattractive and neutral individuals. It was hypothesized that pictures would elicit task-irrelevant evaluative categorization processes and so would novel stimuli (relative to words and familiar stimuli, respectively). Task-irrelevance was examined by assessing P3 peak amplitude to …
Characterization Of The Behavioral And Neurochemical Effects Of Nicotine Withdrawal In Adolescent And Adult Rats., Luis Alberto Natividad
Characterization Of The Behavioral And Neurochemical Effects Of Nicotine Withdrawal In Adolescent And Adult Rats., Luis Alberto Natividad
Open Access Theses & Dissertations
Previous studies have demonstrated that the behavioral effects of nicotine withdrawal are lower in adolescent versus adult rats. However, the neurochemical mechanisms that mediate these developmental differences are presently unclear. Much work has shown that nicotine reward is mediated via enhanced dopamine neurotransmission in the mesolimbic pathway which originates in the ventral tegmental area (VTA) and terminates in several forebrain structures including the nucleus accumbens (NAcc). More recently, studies have shown that nicotine withdrawal produces a decrease in NAcc dopamine transmission, an effect that is believed to serve as a neurochemical marker of withdrawal in adult rodents. The goal of …
Role Of Dorsostriatal D1 And D2 Receptors In Modulating The Kappa Opioid-Mediated Locomotor Activity Of Preweanling Rats: Importance Of Synergistic Activation, Sergios Charntikov
Role Of Dorsostriatal D1 And D2 Receptors In Modulating The Kappa Opioid-Mediated Locomotor Activity Of Preweanling Rats: Importance Of Synergistic Activation, Sergios Charntikov
Theses Digitization Project
Infusions of the nonselective dopamine agonist R( - ) propylnorapomorphine (NPA) into the dorsal striatum of preweanling rats atteuates kappa opioid-mediated locomotor activity. The purpose of this thesis was to ascertain which dopamine receptor subtype (D1 or D2) is responsible for this effect. It was hypothsized that a) D1, but not D2, receptors in the dorsal striatum underlie NPA's ability to attenuate the kappa opioid-mediated locomotor activity of preweanling rats, and b) microinjectng SKF38393 (a D1 agonist), and not quinpirole (a D2 agonist), would attenuate kappa opioid-mediated locomotion.
Effects Of Early Amphetamine Exposure On Memory, Wendy Ann Holmquist
Effects Of Early Amphetamine Exposure On Memory, Wendy Ann Holmquist
Theses Digitization Project
The purpose of the current study was to determine if rat pups treated with amphetamine (AMPH) during a critical time of hippocamal development would exhibit deficits in spatial learning and memory when tested in the Morris water maze during adolescence. Exposure to amphetamine during early postnatal development induces long-term reductions in protein kinase A (PKA) activity. Because PKA activity is known to regulate the production of brain derived neurotrophic factor (BDNF), and reductions in BDNF are associated with memory deficits, it was hypothesized that early exposure to amphetamine would lead to declines in both BDNF levels and memory performance. The …

The Effects, Brain Targets, And Mechanisms Of Estradiol For Affective Behavior, Alicia Ann Walf
The Effects, Brain Targets, And Mechanisms Of Estradiol For Affective Behavior, Alicia Ann Walf
Legacy Theses & Dissertations (2009 - 2024)
Although estradiol (E2) has numerous effects in the central nervous system, this review will focus on addressing the effects of E2 on behaviors related to mood in women and animal models and include recent findings from our laboratory related to this topic. E2's anti-anxiety and anti-depressant-like effects may depend upon many factors (e.g. age, reproductive history/status, time in E2 deficient state before initiation of E2 therapy, regimen and dosing of E2, neuropsychiatric/stress history). First, evidence of how factors may alter responses to E2 in people and in animal models will be discussed. Second, interactions of E2 with the hypothalamic-pituitary-adrenal axis/stress …
Observer Effects Of Non-Sexual Nipple Erection And Their Possible Reproductive Advantages In Human Females, Amy J. Lefevre
Observer Effects Of Non-Sexual Nipple Erection And Their Possible Reproductive Advantages In Human Females, Amy J. Lefevre
Legacy Theses & Dissertations (2009 - 2024)
Nipple erection in women for any purpose other than lactation is somewhat of an evolutionary mystery. In earlier studies I found evidence of nonsexual nipple erection (NSNE) in females in response to anxiety-provoking stimulus material (LeFevre, unpublished). The goal of the present research was to determine what benefits, if any, that NSNE may confer upon females who display this behavior. Specifically, two studies tested the general proposition that non-sexual nipple erection decreases aggressiveness in males and looked at the possibility that cognitive interference may be a mediating factor in aggression de-escalation. Fifty-one undergraduate students (33 male and 18 female) took …
Glossolalia Influences On Stress Response Among Apostolic Pentecostals, Christopher Dana Lynn
Glossolalia Influences On Stress Response Among Apostolic Pentecostals, Christopher Dana Lynn
Legacy Theses & Dissertations (2009 - 2024)
This study tests the hypothesis that long–term experience of Apostolic Pentecostal glossolalia or “speaking in tongues” reduces the reactivity of biological stress response to normal or "daily" stressors. Glossolalia is a form of religious dissociation. Dissociation is a universal capacity often conflated with “trance.” It refers to the partitioning of awareness associated with a variety of cross–cultural forms, from daydreaming and denial to possession trance, shamanic spirit journeys, and dissociative identity disorder. Dissociation is believed to reduce or filter stress by mediating evaluation of potential stressors and reactivity of the mechanisms of biological stress response. Previous studies have examined these …
A Study Of Possible Pre-Cognitive Advantages Of Bilingualism, Marisela Gutierrez
A Study Of Possible Pre-Cognitive Advantages Of Bilingualism, Marisela Gutierrez
Open Access Theses & Dissertations
Past research has suggested that second language acquisition has a beneficial effect on the development of inhibitory control processes in children and adults. This has been referred to as the "bilingual advantage" and is most commonly quantified using the Simon task. Whether the bilingual advantage extends to precognitive mechanisms has not yet been examined. The goals of this study were to examine the bilingual advantage in university students; and to examine whether the bilingual advantage extends to the precognitive filtering mechanism of sensorimotor gating. It was predicted that, as compared to monolinguals, bilingual university students would have greater inhibitory control, …
