The Lived Experience Of The Covid-19 Pandemic Among Mandate-Resistant Adults In Washington State, Amber N. Peterson

Antioch University Full-Text Dissertations & Theses

This study examined the lived experience of self-identified, mandate-resistant adults in Washington state. This study explored participants’ experience of the COVID-19 pandemic, from a retrospective framework by uncovering challenges, silver linings, decision-making, and self-reported mental health. Remote interviews were conducted with nine participants. Participants were between 23–31 years old, mostly male, and over half identified as Black. Through semi structured interviews, data was collected and analyzed using Interpretive Phenomenological Analysis (IPA). Participants described their experiences during the COVID-19 pandemic and highlighted significant changes in the way they lived their lives. Most notably, participants described ways in which they defied COVID-19 …

Assessing Rat Behavioral Response To Novelty, Neha Mathew

Honors Scholar Theses

The hippocampus is the part of the brain that is involved in memory and navigation. Neurons in the hippocampus, known as place cells, fire in specific locations within this region of the brain as the subject navigates through their environment. As these cells fire, they create a map-like representation of this environment. However if the environment is altered in any way, the place cell firing pattern is adjusted to incorporate this new information. This adjustment will inevitably cause subjects to take more time to complete their task. The goal of our testing was to assess how various manipulations, both spatial …

Behavioural Risks In Female Dogs With Minimal Lifetime Exposure To Gonadal Hormones, Melissa J. Starling, Anne Fawcett, Bethany Wilson, James Serpell, Paul Mcgreevy

Physiology Collection

Spaying of female dogs is a widespread practice, performed primarily for population control. While the consequences of early spaying for health are still being debated, the consequences for behaviour are believed to be negligible. The current study focused on the reported behaviour of 8981 female dogs spayed before 520 weeks (ten years) of life for reasons other than behavioural management, and calculated their percentage lifetime exposure to gonadal hormones (PLGH) as a proportion of their age at the time of being reported to the online Canine Behavioral Assessment and Research Questionnaire (C-BARQ). We found that 23 behaviours differed between entire …

Diurnally Active Rodents For Laboratory Research, Roberto Refinetti, G. J. Kenagy

Psychological Sciences Faculty Publications and Presentations

Although inbred domesticated strains of rats and mice serve as traditional mammalian animal models in biomedical research, the nocturnal habits of these rodents make them inappropriate for research that requires a model with human-like diurnal activity rhythms. We conducted a literature review and recorded locomotor activity data from four rodent species that are generally considered to be diurnally active, the Mongolian gerbil (Meriones unguiculatus), the degu (Octodon degus), the African (Nile) grass rat (Arvicanthis niloticus), and the antelope ground squirrel (Ammospermophilus leucurus). Our data collected under 12L:12D light-dark cycles confirmed and expanded …

Adolescent Cannabinoid Exposure Induces A Persistent Sub-Cortical Hyper-Dopaminergic State And Associated Molecular Adaptations In The Prefrontal Cortex., Justine Renard, Laura G Rosen, Michael Loureiro, Cleusa De Oliveira, Susanne Schmid, Walter J Rushlow, Steven R Laviolette

Brain and Mind Institute Researchers' Publications

Considerable evidence suggests that adolescent exposure to delta-9-tetrahydrocanabinol (THC), the psychoactive component in marijuana, increases the risk of developing schizophrenia-related symptoms in early adulthood. In the present study, we used a combination of behavioral and molecular analyses with in vivo neuronal electrophysiology to compare the long-term effects of adolescent versus adulthood THC exposure in rats. We report that adolescent, but not adult, THC exposure induces long-term neuropsychiatric-like phenotypes similar to those observed in clinical populations. Thus, adolescent THC exposure induced behavioral abnormalities resembling positive and negative schizophrenia-related endophenotypes and a state of neuronal hyperactivity in the mesocorticolimbic dopamine (DA) pathway. …

Growing Ideas - Daily Transitions - Time For A Change, University Of Maine Center For Community Inclusion And Disability Studies

Early Childhood Resources

Young children with and without disabilities experience many changes during their day. Daily transitions in early care and education programs take place during an activity, or when children move from one activity to another or one location to another. Transitions include the following: Arriving at or departing from a program; Exchanging toys; Entering or leaving a play area during free choice time; Cleaning up after morning activities and starting a group circle time; Getting dressed to go outside to play; and Shifting from playing with friends to working with a teacher/therapist on a particular skill. Thoughtful planning is needed so …

Academic Predictors And Characteristics Of Self-Reported Juvenile Firesetting, Carrie Howell Bowling, Hatim A. Omar

Pediatrics Faculty Publications

The main purpose of this study was to address gaps in existing research by examining the relationship between academic performance and attention problems with juvenile firesetting. Two datasets from the Achenbach System for Empirically Based Assessment (ASEBA) were used. The Factor Analysis Dataset (N = 975) was utilized and results indicated that adolescents who report lower academic performance are more likely to set fires. Additionally, adolescents who report a poor attitude toward school are even more likely to set fires. Logistic regressions were run to determine if attention problems predicted firesetting and the findings indicated that attention problems are predictive …

Caffeinated Alcohol Use And Expectancies For Caffeine Versus Alcohol, Cathy Lau-Barraco, Ashley N. Linden

Psychology Faculty Publications

Background- Caffeinated alcoholic beverage (CAB) use is related to alcohol-related risk. Limited research has examined outcome expectancies and CAB consumption.

Objectives- This study tested the predictive utility of caffeine and alcohol expectancies in CAB use outcomes (i.e. quantity, frequency, and alcohol-related harms).

Methods- Participants were 419 (302 women) alcohol and caffeine users from a mid-sized urban university. Data collection occurred between August 2010 and December 2011. Participants completed measures of caffeine and alcohol expectancies, alcohol problems, alcohol use, and CAB use.

Results- Caffeine and alcohol expectancies contributed uniquely to approximately 12% of the variability in quantity, 8% in frequency, and …

Skill Learning Strengthens Cortical Representations Of Motor Sequences., Tobias Wiestler, Jörn Diedrichsen

Brain and Mind Institute Researchers' Publications

Motor-skill learning can be accompanied by both increases and decreases in brain activity. Increases may indicate neural recruitment, while decreases may imply that a region became unimportant or developed a more efficient representation of the skill. These overlapping mechanisms make interpreting learning-related changes of spatially averaged activity difficult. Here we show that motor-skill acquisition is associated with the emergence of highly distinguishable activity patterns for trained movement sequences, in the absence of average activity increases. During functional magnetic resonance imaging, participants produced either four trained or four untrained finger sequences. Using multivariate pattern analysis, both untrained and trained sequences could …

The Levels Of Analysis Revisited., Scott A Macdougall-Shackleton

Brain and Mind Institute Researchers' Publications

The term levels of analysis has been used in several ways: to distinguish between ultimate and proximate levels, to categorize different kinds of research questions and to differentiate levels of reductionism. Because questions regarding ultimate function and proximate mechanisms are logically distinct, I suggest that distinguishing between these two levels is the best use of the term. Integrating across levels in research has potential risks, but many benefits. Consideration at one level can help generate novel hypotheses at the other, define categories of behaviour and set criteria that must be addressed. Taking an adaptationist stance thus strengthens research on proximate …

A Survey Of The Management And Development Of Captive African Elephant (Loxodonta Africana) Calves: Birth To Three Months Of Age, Nicole L. Kowalski, Robert H.I. Dale, Christa L. H. Mazur

Scholarship and Professional Work - LAS

We used four surveys to collect information about the birth, physical growth, and behavioral development of 12 African elephant calves born in captivity. The management of the birth process and neonatal care involved a variety of standard procedures. All of the calves were born at night, between 7PM and 7AM. The calves showed a systematic progression in behavioral and physical development, attaining developmental milestones at least a quickly as calves in situ. This study emphasized birth-related events, changes in the ways that calves used their trunks, first instances of behaviors, and interactions of the calves with other, usually adult, elephants. …

Glutamate Receptors In Perirhinal Cortex Mediate Encoding, Retrieval, And Consolidation Of Object Recognition Memory., Boyer D Winters, Timothy J Bussey

Brain and Mind Institute Researchers' Publications

Object recognition is consistently impaired in human amnesia and animal models thereof. Results from subjects with permanent brain damage have revealed the importance of the perirhinal cortex to object recognition memory. Here, we report evidence from rats for interdependent but distinct stages in object recognition memory (encoding, retrieval, and consolidation), which require glutamate receptor activity within perirhinal cortex. Transient blockade of AMPA receptor-mediated synaptic transmission within perirhinal cortex disrupted encoding for short- and long-term memory as well as retrieval and consolidation. In contrast, transient NMDA receptor blockade during encoding affected only long-term object recognition memory; NMDA receptor activity was also …

Client Commitment Language During Motivational Interviewing Predicts Drug Use Outcomes, Paul Amrhein, William R. Miller, Carolina Yahne, Michael Palmer, Laura Fulcher

Department of Psychology Faculty Scholarship and Creative Works

Client language from a motivational interview (MI) and drug use outcome were investigated. Interview videotapes of 84 drug abusers were coded for frequency and strength of utterances expressing commitment, desire, ability, need, readiness, and reasons to change or maintain their habit. Cluster analysis of proportion days abstinent (PDA) revealed 3 groups: high PDA at intake and follow-up (3, 6, 9, 12 months; maintainers); low intake PDA/high follow-up PDA (changers); and low intake PDA/low to moderate follow-up PDA (stragglers). Distinct group patterns emerged for commitment strength (CS) during MI. Clients dishonest in checklist self-report exhibited CS similar to stragglers. CS for …

School Functioning And Violent Behavior Among Young Adolescents: A Contextual Analysis, Amanda Birnbaum, Leslie A. Lytle, Peter J. Hannan, David M. Murray, Cheryl L. Perry, Jean L. Foster

Department of Public Health Scholarship and Creative Works

This paper examines associations between overall school functioning and the frequency of violent behaviors among young adolescents (ages 10–14). The sample included 16 middle schools participating in an unrelated intervention study (on nutrition) in Minneapolis, Minnesota. A School Functioning Index developed to characterize schools’ overall stability, performance, and demographics was constructed using data from public archives and school administrator surveys. Data on violent behaviors and other variables were collected in student surveys in fall 1998 and spring 1999. We used multilevel modeling to assess the effect of school functioning on violent behavior after adjusting for known individual-level covariates of violent …

Fornix Lesions Can Facilitate Acquisition Of The Transverse Patterning Task: A Challenge For "Configural" Theories Of Hippocampal Function., T J Bussey, E Clea Warburton, J P Aggleton, J L Muir

Brain and Mind Institute Researchers' Publications

Configural theories of hippocampal function predict that hippocampal dysfunction should impair acquisition of the transverse patterning task, which involves the concurrent solution of three discrimination problems: A+ versus B-; B+ versus C-; and C+ versus A-. The present study tested this prediction in rats using computer-graphic stimuli presented on a touchscreen. Experiment 1 assessed the effects of fornix lesions when the three problems were introduced sequentially (phase 1: A+ vs B-; phase 2: A+ vs B-, B+ vs C-; phase 3: A+ vs B-, B+ vs C-, C+ vs A-). Fornix lesions significantly facilitated acquisition of the complete transverse patterning …
