"Alcohol Is Not Fun Anymore!": A Study Of Alcohol Expectancies During Covid-19, Sara Mcfarland, Katie Ison, Heather Kissel Phd, Ty Brumback Phd

Posters-at-the-Capitol

College parties normalize alcohol use and students develop expectations about drinking due to peer influence and previous experience with alcohol. Our study investigated changes in alcohol expectancies by collecting cross-sectional data on predictors of alcohol use in young adults before and after the start of the pandemic. Data for 46 participants (mean age=20.74, 72% female) were collected prior to March 2020, while data for an additional 26 participants (mean age=19.27, 80.8% female) were collected starting in 2021. During the laboratory session, participants completed surveys and a structured clinical interview. We examined responses from the Alcohol Expectancy Questionnaire (AEQ). This self-report …

Is The Relationship Between Early Life Stress And Attachment Modulated By Dna Methylation Of The Oxytocin Receptor Gene?, Lidia Boghean

UNO Student Research and Creative Activity Fair

Early life stress (ELS) has been linked to endocrine dysregulation, insecure attachment styles, and adult psychopathology. The enduring effects of ELS are likely regulated by epigenetic mechanisms in which the environment influences gene transcription and protein expression. We investigated oxytocin receptor gene (OXTR) methylation as a potential underlying mechanism by which early life stress affects stress reactivity and attachment later in life in a dog model system. 47 dog-owner dyads were grouped by dog early life history (ELS and non-ELS) and provided blood and saliva samples. Dyads participated in a behavioral attachment paradigm. ELS dogs showed increased methylation at one …

What Makes A Good Therapy Dog? Identifying Factors Associated With Calm Behavior In Therapy Dogs, Kristen Cunningham, Zachary L. Darwish, Rosemary Strasser

UNO Student Research and Creative Activity Fair

Dogs offer a variety of benefits to society, including the use of therapy dogs to provide therapeutic and physiological benefits, enhancing the lives of a wide range of recipients. Unlike service or emotional support animals, therapy dogs provide support to a multitude of individuals, often in hospitals, schools, nursing homes, or other venues. While many studies have examined behavioral assessments of service dog programs, little research has investigated the factors that make a good therapy dog. Therapy dogs must undergo strategic training before becoming certified. The present study seeks to illuminate what factors might distinguish therapy dogs from pet dogs …

An Investigation Of Stimulants: Reviewing Their Effects On The Brain, Including Memory And Microglia, Michael Douchey

UNO Student Research and Creative Activity Fair

Stimulants are a class of drugs that have a variety of effects on the brain, including changes in receptor activity in the brain areas responsible for- memory, attention, emotion, motor control, and the reward pathway. Stimulants may be generally classified by their availability. For example, prescription stimulants, which include drugs such as methylphenidate (Concerta™, Ritalin™) and mixed amphetamine salts (Adderall™), must be prescribed by medical professionals. Another regulated stimulant, albeit one available without a prescription, is nicotine; a highly addictive chemical that is age-restricted by the U.S. federal government. Nicotine is found in tobacco products, and in tobacco-free alternatives including …

Marmosets Respond Consistently To Threats Across Contexts, Sarah Carp

UNO Student Research and Creative Activity Fair

Behavioral traits, such as how adventurous an individual is, can vary both across individuals and within an individual across contexts. However, there is evidence that individuals are stable across time in how they respond to certain stimuli. This consistency in behavioral responses to similar environments is termed a behavioral syndrome, or set of correlated behavior. We assessed the degree to which individual marmoset monkeys were consistent across four behavioral tests that measured different aspects of novelty seeking. The four tasks included exposure to a novel object in a familiar environment, exposure to a novel environment, behavioral flexibility in response to …

Effects Of Naltrexone On Alcohol And Nicotine Use In Female P Rats, Usman Z. Hamid, Michael T. Bardo Ph.D.

Title: Effects of Naltrexone on Alcohol and Nicotine Use in Female P Rats

Author: Usman Z. Hamid, Department of Psychology, University of Kentucky

Faculty Mentor: Michael T. Bardo, Ph.D., Department of Psychology, University of Kentucky

Alcohol is the most commonly abused substance worldwide. It is often co-abused with nicotine, which increases the difficulty of cessation of both alcohol and nicotine. Despite having similar mechanisms of action, there is no single medication to treat the co-abuse. The objective of the current study is to analyze the effects of the opiate antagonist naltrexone on alcohol consumption and the co-use of alcohol and …

A Behavioral Prerequisite For The Genetic Analysis Of Auditory Feature Detection Mechanisms In Female Crickets, Rebecca L. Blisko

Senior Honors Projects

Sexual dimorphism is exhibited across all cricket species and is a central aspect of the mating processes of these insects. Only male crickets possess wing structures and pattern generators in the central nervous system that allow them to produce a mating call that is unique to their species in order to attract conspecific females. Conspecific females possess an auditory feature detection circuit in the central nervous system that is capable of detecting the species-specific frequency and temporal pattern of sound pulses within a male call. In order for dimorphic differences in mating behavior to result in successful continuation of a …

Who's Tweeting Whom: The Influence Of Rearing Condition On Social Integration In Zebra Finches, Zachary L. Darwish

UNO Student Research and Creative Activity Fair

Zebra finches (Taeniopygia guttata) are a gregarious species of finch. Previous work with zebra finches has demonstrated the long-lasting impacts of ear social environment on social behavior in adulthood. Zebra finch chicks were raised by either both parents (biparental) or their mother only (uniparental) and their behavior in an aviary was recorded using passive integrative transponders. Zebra finch ID numbers were recorded every time they entered a feeding station for 31 days. There was a trend for uniparental birds to engage in more visits to a feeding station per event than biparental birds, however, there was no difference …

Neuroendocrine And Psychological Factors Associated With Burnout, Compassion Fatigue, And Reduced Compassion Satisfaction In Mental Health Professionals, Michelle Huffman

UNO Student Research and Creative Activity Fair

Mental health professionals are at increased risk for burnout, compassion fatigue, and reduced compassion satisfaction. Burnout is characterized by emotional exhaustion, depersonalization, and loss of personal accomplishment. Compassion fatigue is a more progressed disruption relative to burnout marked by insomnia/nightmares, arousal, loss of objectivity, isolation, and intrusive thoughts. Compassion satisfaction buffers against burnout and compassion fatigue. Although links between demographic, psychological, and biological factors have been documented, interactions between these factors have not been explored. Mental health professionals completed psychological inventories measuring depression, anxiety, burnout, compassion fatigue, and compassion satisfaction. Saliva samples were collected during the Trier Social Stress Test …

The Effects Of Chronic Partial Sleep Deprivation On Alcohol Consumption And Delta Fos B Accumulation, Kristian Ponder

Showcase of Graduate Student Scholarship and Creative Activities

The present study explores the relation between sleep restriction and alcohol use and the neural substrates that result from chronic behaviors, such as transcription factors. Transcription factor activity is suggested as a possible outcome of chronic behaviors, such as addiction. Sleep is discussed as possible mediating factor in the relationship between specific transcription factors and alcohol. Analysis will focus on brain areas related to both sleep and reward.
