Repeated Treatment With 5-Ht1a And 5-Ht1b Receptor Agonists: Evidence Of Tolerance And Behavioral Sensitization, Jordan Taylor
Repeated Treatment With 5-Ht1a And 5-Ht1b Receptor Agonists: Evidence Of Tolerance And Behavioral Sensitization, Jordan Taylor
Electronic Theses, Projects, and Dissertations
Serotonin has been found to regulate several cognitive and physiological functions, and its role in depression and other neuropsychiatric disorders has been a focus of research. More specifically, a wealth of research regarding serotonin focuses on serotonergic medications in the treatment of neuropsychiatric disorders, such as depression and anxiety, and stimulates the 5-HT1A and 5-HT1B receptors. Within the last decade, there has been an increase in prescriptions of psychotropic medication for children, however, the efficacy and adverse effects of these drugs have not been evaluated in younger populations. While antidepressants reduce symptoms of depression in adults, they are …
Classical Conditioning Of Cognitive States, Arthur Burns
Classical Conditioning Of Cognitive States, Arthur Burns
Neuroscience Honors Papers
Classical conditioning has been a fundamental concept and practice throughout the history of psychology. While classical conditioning traditionally seeks to elicit target behaviors in correlation to specific stimuli, we sought to do the same with cognitive states in place of behaviors. Specifically, we wanted to determine the effectiveness of conditioning states of cognitive arousal in human participants in conjunction with cues presented in a designed learning task. We designed a cognitive task specifically for this research, referred to as “the Tone Pitching Task”, which utilized a combination of working memory and mental processing in order to elicit cognitive arousal and …
The Effects Of D2 Receptor Modulation On Locomotor Development In Danio Rerio, Isaiah Thomas Mcroberts
The Effects Of D2 Receptor Modulation On Locomotor Development In Danio Rerio, Isaiah Thomas Mcroberts
Senior Projects Spring 2022
This study utilized a novel design to investigate the sensitivity of D2 dopamine receptors to modulating compounds through multiple exposures over early development of zebrafish larvae. Zebrafish were dosed for 30 minutes from 5-8 days post fertilization (dpf) with 16µ/mol of either a D2 antagonist, haloperidol, or a D2 agonist, quinpirole hydrochloride. Two other groups were then dosed with these compounds from 9-12dpf. The effects of D2 receptor modulation were measured by analyzing motor activity on measures of movement distance, frequency, and velocity. Results indicated that larvae dosed with haloperidol on 5dpf had increased activity after the first dosage, but …

Effects Of A Novel, Non-Toxic Histone Deacetylase Inhibitor On Hippocampal Memory Formation, Histone Acetylation, And Bdnf Gene Expression In Male Mice, Sarah Brianna Beamish
Theses and Dissertations
Memory dysfunction is a common symptom of aging, neuropsychiatric disorders, and neurodegenerative disorders, yet truly effective treatments for memory loss do not exist. De novo gene transcription is a molecular requirement for long-term memory formation. The transcription of genes related to synaptic plasticity and learning are regulated in part by histone acetylation, an epigenetic mechanism that regulates chromatin accessibility. Pharmacological compounds that maintain histone acetylation, called histone deacetylase inhibitors (HDACi), enhance memory by preventing deacetylation of core histone proteins, which initiates binding of transcriptional machinery to open chromatin. Therefore, HDACi are potentially promising therapeutics that could be used to prevent …
Exploring Tactile Art-Making With Deafblind Students And Their Families: An Opportunity For Creative Play, Alice Rodgers
Exploring Tactile Art-Making With Deafblind Students And Their Families: An Opportunity For Creative Play, Alice Rodgers
Expressive Therapies Capstone Theses
The impact of a deafblind diagnosis on an individual’s mental health and the well-being of the family involved can be profound. However, current research and available literature for the mental health treatment and therapy practices of deafblind persons and their families is limited (Kyzar et al., 2016; “WFDB Global Report 2018,” n.d.). This thesis used the Leeds Family Psychology and Therapy Service principles (Leeds FPTS) and the Expressive Therapies Continuum with established deafblind teaching strategies to facilitate an original arts-based community project entitled: “Things We Like.” This project provided an opportunity for deafblind students (ages three to 22) and their …
Viability Of Physiologically Timed Relaxation Interventions In Children With Asd, Nicholas Mendez
Viability Of Physiologically Timed Relaxation Interventions In Children With Asd, Nicholas Mendez
CMC Senior Theses
Autism Spectrum Disorder (ASD) is an increasingly common developmental disorder that changes how people experience the world and affects individuals’ social interactions and often leads to many adverse behaviors. Current literature dictates that a primary contributor to these adverse behaviors is that those with ASD have difficulty determining their own emotional states and determining the physiological signals that their body sends them. A study by Dr. Sarabadani et al. determined that it was possible to monitor the physiology of an individual with ASD and correlate certain signals to emotions, such as stress. These findings indicate the feasibility of establishing a …
Circadian Variations And Risky Decision Making, Sana Sra
Circadian Variations And Risky Decision Making, Sana Sra
Scripps Senior Theses
Over the past decades, decision making under risk has garnered a great amount of attention both in the field of economics and psychology. Although state-dependent variabilities of risk taking are well-documented, little is known about the effects of a person’s preferred time of day, or chronotype, in risky decision making. Under circumstances of circadian mismatch (e.g., when an “early bird” makes decisions in the evening), research suggests that decision making may reflect a greater reliance on heuristics, such as using stereotypes in social judgments. However, the effects of circadian mismatch on heuristics in risky decision making are relatively unexplored. This …
Relations Among Maternal And Paternal Behavior And Children's Stress Biology, S.K. Jiaming Lin, Stacey N. Doan, John Milton
Relations Among Maternal And Paternal Behavior And Children's Stress Biology, S.K. Jiaming Lin, Stacey N. Doan, John Milton
Scripps Senior Theses
Parenting behavior has been shown to have a wide range of effects, influencing children’s psychological and biological stress outcomes. Most research focuses on maternal parenting behaviors, with few studies observing the effects of paternal behaviors or the influence of both parents on their children. In this study, the relationship between maternal and paternal parenting behaviors was examined in its association to predict children’s cortisol levels. Cultural differences in parenting styles was also observed. American (N=86) and Chinese (N=97) families participated in the study, with parents reporting their behaviors. Children’s cortisol was collected during a stressor task and correlational analysis was …
Possible Breakdown Of Dopamine Receptor Synergism In A Mouse Model Of Huntington's Disease, Samantha F. Kennedy
Possible Breakdown Of Dopamine Receptor Synergism In A Mouse Model Of Huntington's Disease, Samantha F. Kennedy
University of New Orleans Theses and Dissertations
The model of basal ganglia function proposed by Albin, Young and Penney (1989) describes two anatomically independent motor pathways, the direct and indirect. However, under normal conditions striatal dopamine (DA) is required for the expression of motor behavior, and DAergic control of the two pathways (via D1 and D2 receptors, respectively) is dependent on co-activation. We tested for a possible breakdown of D1/D2 synergism using transgenic R6/1 mice bearing the human huntingtin allele (Htt). Motor stereotypy, observed prior to the onset of HD-related symptoms, was rated on a 5-point scale following activation of: A) D1 receptors alone, B) D2 receptors …
Do Flashbulb Memories Transmit Across Generations? 9/11 As A Case Study, Shanique Meyler
Do Flashbulb Memories Transmit Across Generations? 9/11 As A Case Study, Shanique Meyler
Student Theses
Psychologists have only recently begun to examine the extent to which personal memories transmit across generations. When they have, they typically focus on family stories (see Merrill & Fivush, 2016) or memories of historical events (Svob & Brown, 2012). The present study extends this line of research to flashbulb memories, or memories of an individual’s circumstances when first learning about a consequential, historical event (Brown & Kulik, 1977). To this end, the present study examines the extent to which flashbulb memories surrounding the events of the terrorist attacks on 9/11 transmit to the next generation. The results suggest that flashbulb …
The Relationship Of Early Class Start Times On Sleepiness And Driving Behaviors In An Emerging Adult Population, Jessica L. Fry
The Relationship Of Early Class Start Times On Sleepiness And Driving Behaviors In An Emerging Adult Population, Jessica L. Fry
Psychology Theses & Dissertations
Teenage driver sleepiness is a recent concern for preventing motor vehicle fatalities. Early school start times limit the amount of sleep teenage high school students acquire during the week and have been related to increased crash risk. The current study extends this finding to teenage and emerging adult college students. The author examined the link between sleepiness and teenage driving behaviors, including the relationship between school start times and sleepiness. In all, 536 participants were recruited to participate in an online survey assessing driving and sleep behaviors. Correlations and path analysis found that sleepiness fully mediated the relationship between early …
Functional Analysis And Treatment Of Self-Injurious Feather Plucking In A Black Vulture (Coragyps Atratus), Kristen L. Morris
Functional Analysis And Treatment Of Self-Injurious Feather Plucking In A Black Vulture (Coragyps Atratus), Kristen L. Morris
Thesis Projects
Feather plucking (FP) is a maladaptive behavior observed in captive avian species. This self-injurious behavior results in damage to and removal of feathers and skin tissue, resulting in animal welfare and financial consequences. The etiology and maintenance of FP have been hypothesized through medical and environmental processes, yet a definitive solution has not been found. The current study investigated the environmental variables maintaining the FP of a Black Vulture (Coragyps atratus), as well as evaluated a function-based treatment for this behavior. The behavior was found to be maintained by positive reinforcement in the form of contingent attention. Treatment …

The Interaction Between Spatial Working And Reference Memory In Rats On A Radial Maze, Nicole Ann Guitar
The Interaction Between Spatial Working And Reference Memory In Rats On A Radial Maze, Nicole Ann Guitar
Undergraduate Honors Theses
The present study investigated the interaction between working and reference spatial memory in an effort to develop an animal model of this interaction. Twelve male Long-Evans rats were tested on an eight-arm radial maze in a two-phase procedure. In the study phase, a rat was allowed to enter four randomly selected arms for a food reward placed at the end of each arm. The test phase allowed the rat access to all eight arms, but only the previously unentered arms contained food. Two of the correct test arms were defined as reference memory arms because they were always correct. The …
From Passive Receptacles To Active Contenders: Ovulation And Intrasexual Competition In Human Females, Andres E. Munoz
From Passive Receptacles To Active Contenders: Ovulation And Intrasexual Competition In Human Females, Andres E. Munoz
Honor Scholar Theses
Recent evidence has suggested that ovulation in humans might be accompanied by subtle cues. Furthermore, several studies have suggested that women engage in intrasexual competition, or competition with members of the same sex, with the aim of obtaining high quality mates. This competition involves the use of complex strategies including self-promotion and rival derogation. The link between ovulation and intrasexual competition remains largely underexplored, although a few studies have suggested that intrasexual competition might become intensified during ovulation. This paper explores the relationship between ovulatory cue detection and intrasexual competition and outlines two research proposals for future analysis of this …
Effects Of Food Dispersion On Dominance Related Behaviors In Garnett's Bushbaby (Otolemur Garnettii)?, Kyle Daniel Edens
Effects Of Food Dispersion On Dominance Related Behaviors In Garnett's Bushbaby (Otolemur Garnettii)?, Kyle Daniel Edens
Dissertations
Socio-ecological theorists tie primate social structure diversity to variations in habitats within which primate species reside. This premise permits laboratory researchers to investigate specific factors that influence or relate to social structure formation and maintenance. The focus of the current investigation was three fold. We first aimed to determine the relationships between traditional and non-traditional behavioral measures of dominance, then evidence for dominance hierarchy formation was examined, and various hypotheses were tested to discern if adjustments in the foraging context altered social behaviors in Garnett’s bushbaby (Otolemur garnettii). It was determined that animals likely to displace conspecifics were …

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 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 …
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' …
Conservatism In A Bayesian Probability Situation As A Function Of The Sex Of The Subject, Paul Frederick Miller
Conservatism In A Bayesian Probability Situation As A Function Of The Sex Of The Subject, Paul Frederick Miller
All Master's Theses
The present study was designed to examine whether the conservatism present in a Bayesian probability situation could be partially attributable to the sex of the subjects performing the task. The experimental design required that the subjects estimate the probabilities of occurrence of two independent events. They were then given an opportunity to revise their estimates as additional information was experimentally introduced into the situation. These estimates were compared to estimates calculated from Bayes’ theorem.
