Attention And Criminal Charge, Profile And Description: The Effect On Prospective Person Memory, Lindsey Nicole Sweeney

Graduate Theses and Dissertations

Prospective person memory is the ability to recognize and react to a missing or wanted individual that one has been asked to be on the lookout for in the future. Prospective person memory relies on several processes including face recognition, event-based prospective memory, and attention. Only recently has research on the role of visual attention on prospective person memory been examined. In this dissertation, the gap between prospective person memory and attention is addressed. Although research on prospective person memory is steadily increasing, the research in this area is still in its infancy and the exact memory mechanisms that affect …

Hand Preference For Tool-Use In Capuchin Monkeys (Cebus Apella) Is Associated With Asymmetry Of The Primary Motor Cortex, Kimberley A. Phillips, C. R. Thompson

Psychology Faculty Research

Skilled motor actions are associated with handedness and neuroanatomical specializations in humans. Recent reports have documented similar neuroanatomical asymmetries and their relationship to hand preference in some nonhuman primate species, including chimpanzees and capuchin monkeys. We investigated whether capuchins displayed significant hand preferences for a tool use task and whether such preferences were associated with motor-processing regions of the brain. Handedness data on a dipping tool-use task and high-resolution 3T MRI scans were collected from 15 monkeys. Capuchins displayed a significant group-level left-hand preference for this type of tool use, and handedness was associated with asymmetry of the primary motor …

The Influence Of Widowhood And Sociodemographic Moderators On Dementia And Alzheimer's Disease Risk, Daniel Joseph Hatch

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Dementia and Alzheimer’s disease (AD) are dramatic public health problems. In recent years, researchers have uncovered evidence demonstrating that chronic stress can lead to these conditions. Because of this, researchers have also investigated whether widowhood, one of the most stressful life events, may also lead to dementia and AD. However, these studies are conflicting, and few have investigated whether the influence of widowhood on dementia and AD varies in different contexts associated with aging and widowhood. For instance, evidence suggests that widowhood may exert greater influence among males and among those with a history of depression. Other such contextual factors …

Mothers' And Fathers' Attachment Relationships With Children Who Have Disabilities, Sheila Lopez

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Research has found that attachment relationships between parents and children are formed independent of each other and have different outcomes for the child. Very little research regarding parent-child attachment relationships has been done with children who have a disability. This study aimed to learn more about whether differences exist in attachment relationships between mothers and fathers and whether or not the child has a disability. Results indicate that fathers of children with a disability appear to have less secure attachments with their children compared to fathers of typically developing children as well as mothers of children with and without disabilities. …

Concurrent Neurological And Behavioral Assessment Of Number Line Estimation Performance In Children And Adults, Joseph Michael Baker

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Understanding the brain’s response to common math-learning activities may help improve math education. For example, by imaging the brains of typically developing children and adults throughout a number line estimation task, it is possible to establish a baseline of what “typical” brains do in such situations. Thus, comparisons may be made to determine the degree to which brain functioning differs between typical and atypical math learners. Moreover, by identifying methods that may increase the brain’s response to real-world math activities, it may be possible to improve the math learning process for typical and atypical learners alike.

Brain imaging devices such …

The Psychological And Physiological Effects Of Using A Therapy Dog In Mindfulness Training, Courtney L. Henry

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study examined the psychological and physiological effects of adding animal-assisted therapy to a modified mindfulness-based stress reduction program (MBSR) for clients experiencing psychological distress, including anxious and depressive symptoms. State and trait mindfulness, state and trait anxiety, psychological distress, blood pressure, and heart rate were collected during each session of the intervention from college students recruited at Utah State University. Results support that participants experienced less anxiety and depressive symptoms and increased mindfulness skills from pre- to posttreatment. No significant difference was found between the control and experimental groups, indicating that that interaction with a therapy dog had no …

A Comparison Of Resistance To Extinction Following Dynamic And Static Schedules Of Reinforcement, Andrew R. Craig

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Behavioral momentum theory states that the Pavlovian stimulus-reinforcer relation governs resistance to extinction. Thus, higher baseline reinforcer rates should produce more persistent behavior than lower baseline reinforcer rates. Though this positive relation generally is observed when behavior is maintained and subsequently disrupted in multiple schedules, the opposite relation is observed when single schedules are used. An alternative framework of extinction performance based on Bayesian change detection may be applied intuitively to describe resistance to extinction in single schedules of reinforcement. This approach asserts that detection of changes in reinforcer rates during extinction should be easier following training with rich reinforcer …

Attentional Factors In Temporal Distortion: The Effects Of Food Availability On Responses Within The Interval Bisection Task, Robert N. Johnson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Time estimation is a process that underlies many complex behaviors. Accurately timed performance depends upon some biological mechanism, which may be revealed by experimental methods. There have been several proposals on the subject of the function of the timing mechanism, some of which have revealed contradictory findings regarding the effect of distraction on timing. Whereas some studies have revealed underestimation (reports of time moving more slowly than it actually is) of the target interval following distracter presentation, others have revealed generalized disruption (no meaningful evidence of timing). The purpose of the present study was to determine whether food presentation for …

Predictors Of Father-Child And Mother-Child Attachment In Two-Parent Families, Jared P. Benware

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

Jared Benware, M.S. and Gretchen Gimpel Peacock, Ph.D. at Utah State University examined parent-child attachment in two-parent families. Specifically, the relationship between mother-child and father-child attachment, the relationship between a child's temperament and parent-child attachment, and the relationship between the attachment and the amounts of time a parent spends away from his or her child. The researchers solicited parents as participants to complete questionnaires that measure parent-child attachment and the temperament of their child. This study focused especially on providing more information on the connection between father-child attachment and mother-child attachment rather than focusing only on mothers as the primary …

The Role Of Hardiness, Family Hardiness, And Parenting Self-Efficacy On Parenting Stress In Adoptive Parents, Erica Danielle Raisanen

Master's Theses

Adoptive parents are at risk for experiencing a high level of parenting stress (McGlone, Santos, Kazama, Fong, & Mueller, 2002) throughout the duration of the adoption experience. Adoptee background factors have been found to contribute to increased levels of parenting stress and distress in adoptive parents (Brooks, Simmel, Wind, & Barth, 2005; McDonald, Lieberman, Partridge, & Homby, 1991; McGlone et al., 2002). Increased parenting stress has been associated with negative outcomes for both parent and child (Ang, 2008; Deater-Deckard, Smith, & Ivy 2005; Morgan, Robinsion, & Aldridge, 2002). Hardiness, family hardiness and parental self-efficacy are protective factors that have all …

Notions Of Spirits As Agents Of Mental Illness Among The Akan Of Ghana: A Cultural-Psychological Exploration, Annabella Opare-Henaku

Theses and Dissertations

The study explores lay conceptualizations of mental illness among the Akans of Ghana as influenced by their cultural worldview. Akan, the largest ethnic group in Ghana, is noted for the use of supernatural attributions for various health-related issues. The supernatural attributions are based on Akan ontological belief that the universe is unitary such that there is no clear distinction between physical and spiritual occurrences. This worldview guides Akans in how they deal with a wide range of issues including their mental health. Clinicians and other mental health professionals who rely solely on biomedical approaches to mental health fail to meet …

Effect Of Emotional Cues On Memory Recall And Response Time, Rachel Rahn

Symposium on Research and Creative Expression (SORCE)

Combining electroencephalography, the recording of the brain's electrical activity, with other psychological research techniques allows the link between memory and emotion to be investigated. This study, which is currently in the pilot phase, investigates the effect of emotions on performance in a memory test. Subjects are shown written memory cues with or without accompanying photos of strong facially-expressed emotions and later prompted to recall the written cues. By monitoring brain activity and recall success rate, emotion's effect on memory in this context can be determined, including what brain regions are stimulated by the emotion-memory link and the improvement or impairment …

Facilitating Positive Reactions To Psychological Labels, Stephanie Kuipers

Symposium on Research and Creative Expression (SORCE)

Receiving a psychological label is often a life-changing experience. Some people feel relieved and hopeful upon discovering a name for their problem, while others become scared and depressed about the implications of receiving such a label (Proudfoot et al., 2009). This study attempts to identify factors that may affect whether a client has a positive or negative reaction to psychological labeling. Specifically, three factors were examined: use of language, client personality, and type of diagnosis. Each participant was randomly assigned to read one of four short narratives in which they imagined themselves in the depicted situation. All narratives portrayed someone …

Four Virtues: Interventions For Goodness' Sake, Caroline Lavelock

Theses and Dissertations

Empirical interest in promoting virtues has dramatically increased over the last decade. The present study will focus primarily on the warmth-based virtues of forgiveness and humility, and the conscientiousness-based virtues of patience and self-control. I introduced participants (N = 135) to a workbook intended to promote one of these four virtues, or to promote general positivity for participants in a workbook control condition. I hypothesized that virtue workbooks would produce higher levels of the target virtue, more so than in both a non-action control condition (n = 33) and in a control condition that completes a workbook that promotes general …

Maternal Employment And The Mother-Child Relationship, Marie Ortega, Margaret Gross, Helena Karnilowicz, Veronica Kreter, Lindsey Butrera, Shirley Mcguire, Nancy Segal

Creative Activity and Research Day - CARD

It has been suggested that a mother’s employment status affects her relationship with her children. This study examined whether children of stay-at-home mothers showed differences in the mother-child relationship than those of employed mothers. Participants were 252 sibling-pairs, 8-13 years, in the Twins, Adoptees, Peers and Siblings Study. Children completed measures on maternal warmth, trust, and conflict. Mothers reported their occupations. Independent t-tests were used to compare mean scores for maternal warmth, trust and conflict. There was no significant statistical difference between the groups, which suggests maternal employment does not affect relationship quality. Follow up analyses will examine biological …

Oxytocin, Or “Cuddle Hormone” Genotype In Titi Monkeys, Hannah Page, Dr. Dee Higley

Journal of Undergraduate Research

I used my ORCA grant to attend ASP, go on an internship at the CNPRC, and pursue research involving the oxytocin, or “cuddle hormone” genotype in titi monkeys.

An Exploration Of Men's Attitudes Regarding Depression And Help-Seeking, Brian Paul Cole

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Despite significantly higher risk of suicide and co-morbid substance abuse, college age men are far less likely than college age women to seek help when depressed (ACHA, 2010). This “gender gap” has led researchers to suggest that college men are experiencing a mental health crisis (Davies, Shen-Miller, & Isacco, 2010). Several theories have been suggested for this gender gap including: (a) barriers caused by male gender socialization, (b) inaccurate diagnostic criteria, and (c) men experience different symptoms when depressed (Cochran, 2005; Levin & Sanacora, 2007). Additionally, the current researcher hypotheses that fear of femininity is a core aspect of the …

Sex Ratios And Gender Role Perceptions, Elizabeth A. Boger

Department of Psychology: Dissertations, Theses, and Student Research

This research investigated whether altering perceived sex ratios, defined as the number of men per 100 women, influenced gender role perceptions among college students. The specific area of interest within sex ratios was the effect of high versus low sex ratios. Existing work on the topic of sex ratios focused on demographic data.

The focus of these studies was the impact of changing sex ratios on the individual, specifically participants’ perceptions of romance, dating and women’s gender roles. I hypothesized that for high sex ratios, participants would endorse statements of traditional dating and romance schemes, traditional women’s roles, and socially …

The Effects Of Selected Drugs On The Memory Recall Of Sleep Deprived Mice, Jenn Pauldurai

Capstone Research Projects

Humans often make use of the neurotransmission altering effects of drugs such as caffeine, ephedrine, and ethanol. These drugs induce changes in memory and learning ability, specifically when used for sleep deprivation. English white mice (Mus musculus) have been shown to exhibit similar cognitive changes when administered drugs while sleep deprived. A sample of 20 mice was divided into three experimental groups (each group receiving a different drug) and one control group. Maze-testing demonstrated that mice performance decreased with sleep deprivation (Treatment-1) but all groups returned to baseline performance when injected (IP) with selected drugs (Treatment-2), regardless of …

Attitudes Toward Science (Ats): An Examination Of Scientists' And Native Americans' Cultural Values And Ats And Their Effect On Action Priorities, Adam T. Murry

Dissertations and Theses

Science has been identified as a crucial element in the competitiveness and sustainability of America in the global economy. American citizens, especially minority populations, however, are not pursuing science education or careers. Past research has implicated `attitudes toward science' as an important factor in the public's participation in science. I applied Ajzen's (1991) Theory of Planned Behavior to attitudes toward science to predict science-related sustainability-action intentions and evaluated whether scientists and Native Americans differed in their general attitudes toward science, cultural values, and specific beliefs about science. Analyses revealed that positive attitude toward science and the cultural value of individualism …

Children Who Have Experienced Trauma: An Examination Of The Role Of Race, Ethnicity, And Cultural Factors In Presenting Symptoms And At Three Month (Or First Recorded) Follow Up, Stephanie Susanne Genser Wolf

Theses and Dissertations

Child traumatic stress is a pervasive problem that affects the well-being and healthy development of children from all races, ethnicities, and cultures. Major factors known to affect trauma symptoms include type of trauma, level or severity of trauma exposure, and age and gender of children. Utilizing Bronfenbrenner’s ecological model, this study measured the additional influence of children’s race, ethnicity, and cultural factors on symptoms after trauma. A dataset of children in treatment after experiencing trauma (0-21 years, N = 10,115) from The National Child Traumatic Stress Network (NCTSN), a federally funded initiative that collected longitudinal data across 56 research and …

Does Movie Viewing Cultivate Unrealistic Expectations About Love And Marriage?, Lauren Galloway

Graduate Research Symposium (2010 - 2017)

The present study investigated the connection between romantic movie viewing frequency and endorsement of dysfunctional beliefs for romantic relationships in a university-based sample of 228 participants. Respondents completed a questionnaire in which they reported demographic information as well as responses to the several scales that measure endorsement of romantic ideals. I base this investigation of Segrin and Nabi’s (2002) examination of television viewing habits and proclivity for unrealistic expectations of sex, love, and marriage. Both the current study and the investigation conducted by Segrin and Nabi (2002) support the supposition that media play a part in reinforcing beliefs about coupleships. …

Adaptive Memory: Evaluating Alternative Forms Of Fitness-Relevant Processing In The Survival Processing Paradigm, Joshua Sandry, David Trafimow, Michael J. Marks, Stephen Rice

Department of Psychology Faculty Scholarship and Creative Works

Memory may have evolved to preserve information processed in terms of its fitness-relevance. Based on the assumption that the human mind comprises different fitness-relevant adaptive mechanisms contributing to survival and reproductive success, we compared alternative fitness-relevant processing scenarios with survival processing. Participants rated words for relevancy to fitness-relevant and control conditions followed by a delay and surprise recall test (Experiment 1a). Participants recalled more words processed for their relevance to a survival situation. We replicated these findings in an online study (Experiment 2) and a study using revised fitness-relevant scenarios (Experiment 3). Across all experiments, we did not find a …

Predictors Of Preschool Children's Peer Interactions: Temperament And Prosocial Behavior, Ibrahim H. Acar

College of Education and Human Sciences: Dissertations, Theses, and Student Research

The current study was a correlational study that examined children’s temperament (inhibitory control and shyness) and prosocial behavior as predictors of preschool-aged children’s peer interactions. The current study also examined the moderating effects of inhibitory control and shyness on relation between children’s prosocial behavior and peer interactions. Participants were 40 children (19 boys) aged from three to five enrolled in eight different preschools in a Midwestern city. It was hypothesized that children’s prosocial behavior and temperament (inhibitory control and shyness) would be correlated with preschool children’s peer interactions, operationalized as sociability, communication, assertiveness, conflict, and a composite peer interactions domain. …

The Impact Of Cumulative Risk On Parenting Behaviors As Mediated By Parental Distress, Courtney E. Green

Senior Honors Theses

Cumulative risk is a salient construct addressed in family dynamics research. There have been multiple relationships established among cumulative risk, parenting, and child outcomes through previous research. The current study furthered this body of research by addressing the role of parenting distress within models predicting parenting behaviors within a context of risk. Cumulative risk, parenting, child behavior, and transactional relationships highlighted the relationships between an environment of risk and resulting parenting outcomes. It was predicted that parental distress will act as a mediator variable between the baseline cumulative risk and later parenting behaviors. This hypothesis was tested using data from …

Getting A Grip On Memory: Unilateral Hand Clenching Alters Episodic Recall, Ruth E. Propper, Sean E. Mcgraw, Tad T. Brunyé

Department of Psychology Faculty Scholarship and Creative Works

Unilateral hand clenching increases neuronal activity in the frontal lobe of the contralateral hemisphere. Such hand clenching is also associated with increased experiencing a given hemisphere’s “mode of processing.” Together, these findings suggest that unilateral hand clenching can be used to test hypotheses concerning the specializations of the cerebral hemispheres during memory encoding and retrieval. We investigated this possibility by testing the effects of a unilateral hand clenching on episodic memory. The hemispheric Encoding/Retrieval Asymmetry (HERA) model proposes left prefrontal regions are associated with encoding, and right prefrontal regions with retrieval, of episodic memories. It was hypothesized that right-hand clenching …

The Effects Of Physical Activity And Excerise On Well-Being, Jatha Miner

The Review: A Journal of Undergraduate Student Research

A growing amount of research suggests that regular physical activity can have both psychological and physiological benefits to the aging process. Well being, a global psychological state, has been found to be positively influenced by physical activity, even after short durations. The present study investigated the components of happiness, satisfaction with life, and social support, all of which are believed to be parts of overall well-being. Six older, community dwelling adults (M age • 64.5) who recently added physical activity to their lifestyles were surveyed and observed over a five-week period. Pre and post test scores were compared and attendance …

Fallow Deer Polyandry Is Related To Fertilization Insurance, Elodie F. Briefer, Mary E. Farrell, Thomas J. Hayden, Alan G. Mcelligott

Ethology Collection

Polyandry is widespread, but its adaptive significance is not fully understood. The hypotheses used to explain its persistence have rarely been tested in the wild and particularly for large, long-lived mammals. We investigated polyandry in fallow deer, using female mating and reproduction data gathered over 10 years. Females of this species produce a single offspring (monotocous) and can live to 23 years old. Overall, polyandry was evident in 12 % of females and the long-term, consistent proportion of polyandrous females observed, suggests that monandry and polyandry represent alternative mating strategies. Females were more likely to be polyandrous when their first …

Combatting Dental Anxiety In Patients, Gretchen Osdoba

Natural Science Student Work

Dental Anxiety is a highly debilitating condition that can keep people away from the dentist and from receiving critical care. This can lead to serious medical conditions that could have easily been prevented through proper dental care. The purpose of this paper is to describe the nature of dental fear and the different treatment options available. I will focus on helpful traits of dentists and the use of psychological treatments, nitrous oxide, anti-anxiety medications, and general anesthesia to reduce this fear. I will also discuss a comparison of a psychological treatment and an anti-anxiety medication as short-term and long-term treatment …

The Relationships Of Sleep Quality, Length, And Napping To Physical Performance, Rebecca M. Hoffmann

Doctoral Dissertations

College students suffer from more sleep disturbances than the general population. Sleep difficulties can lead to lower levels of performance, memory, and cognitive ability. Sleep quality is known to impact individuals' physical and psychological health. The relationship between sleep variables (i.e., sleep quality, sleep length, sleepiness, and a nap/relaxation) and physical performance (i.e., flexibility, grip strength, and peak performance) has not been fully examined. The purpose of this study was to explore the relationship between sleep quality, sleep length, and sleepiness and physical performance (e.g., flexibility, grip strength, and peak power), as well as to determine if a short nap …
