Socialising Piglets In Lactation Positively Affects Their Post-Weaning Behaviour, Talia Morgan, John Pluske, David Miller, Teresa Collins, Anne L. Barnes, Françoise Wemelsfelder, Patricia A. Fleming

Sentience Collection

Although commercial farrowing sheds keep individual litters separated, previous studies have suggested that housing systems that allow socialisation of piglets pre-weaning can reduce aggression after weaning. This study tested whether pigs socialised with non-littermates pre-weaning would show less aggression during mixing at weaning (when piglets are taken from their sows and mixed in group housing), and whether socialisation influenced the time budgets or behavioural expression of piglets at weaning. In total, 353 piglets were followed from birth through to one week after weaning. Piglets from 24 sows were allowed to socialise in groups of four litters (‘socialised’ treatment group) from …

Emotional Engagements Predict And Enhance Social Cognition In Young Chimpanzees, Kim A. Bard, Roger Bakeman, Sarah T. Boysen, David A. Leavens

Sentience Collection

Social cognition in infancy is evident in coordinated triadic engagements, that is, infants attending jointly with social partners and objects. Current evolutionary theories of primate social cognition tend to highlight species differences in cognition based on human-unique cooperative motives. We consider a developmental model in which engagement experiences produce differential outcomes. We conducted a 10-year-long study in which two groups of laboratory-raised chimpanzee infants were given quantifiably different engagement experiences. Joint attention, cooperativeness, affect, and different levels of cognition were measured in 5- to 12-month-old chimpanzees, and compared to outcomes derived from a normative human database. We found that joint …

Oh, Behave! Behavior As An Interaction Between Genes & The Environment, Emily G. Weigel, Michael Denieu, Andrew J. Gall

Cognitive Function In The Alcohol Addiction Treatment Population, Suranee Abeyesinhe

Loma Linda University Electronic Theses, Dissertations & Projects

Chronic alcohol abuse has been linked to several cognitive deficits, such as problems with spatial processing, decreased executive functioning, impaired verbal fluency, poor working memory, response inhibition, and social problems such as aggression and social deviance. In order for patients to benefit from treatment, they must be able to utilize multiple cognitive functions. Research has shown that patients suffering from cognitive impairments are much more likely to drop out of treatment early, thereby lending them to higher relapse rates. This study aimed to identify cognitive deficits present in the alcohol addiction treatment population, demographic factors associated with higher levels of …

The Impact Of Physical Activity On Depressed Mood In Older Seventh-Day Adventists, Benjamin J. Silber

Loma Linda University Electronic Theses, Dissertations & Projects

Research has shown physical activity (PA) to result in a reduction in depressed mood. The effects have been examined for different age groups, however, it is unclear whether PA effects differ in older adults. A prospective cohort study (N = 6,463) examined duration and intensity of PA in relation to mood in the Biopsychosocial Religion and Health Study (BRHS). Depressed mood indices were expected to be predicted by lower levels of PA and individuals in younger age groups were expected to receive a greater reduction in depressed mood after PA than those in older age groups. Previous PA (minutes of …

Effects Of Cigarette Smoking On Neurocognitive Performance In Dementia Patients, Christina Mannino

Loma Linda University Electronic Theses, Dissertations & Projects

Dementia has become a serious problem worldwide due to the rapidly increasing incidence rate and the lack of effective treatments that cure or slow disease progression, and thus. prevention is crucial. Some studies suggests that cigarette smoking may increase the risk of developing dementia, but others suggest that smoking may have a neuroprotective effect. To clarify our understanding of the relationship between cigarette smoking and dementia, this study examined the effects of smoking on multiple cognitive domains via secondary data analysis of a sample consisting of 54% female subjects with an average age of 58±13 years. Measures of executive function, …

Changes In Emotion Drive Perceptual Level Shifts: Global Vs. Local Processing, Seda Terzyan

Loma Linda University Electronic Theses, Dissertations & Projects

Different emotional states have been implicated in bringing about specific changes in attention, with positive emotions globalizing attention and negative emotions localizing attention (Fredrickson, 2004). Biases in attentional processes have been associated with the development and maintenance of emotional disorders, anxiety being the most common. Previous studies have shown that anxious individuals present with a bias toward negative information and more readily employ localized attentional processes (Macleod, 2002). This finding demonstrated a link between perceptual levels of attention with higher order conceptual attention, which in turn influences emotional states. Many researchers have explored this relationship, including Fredrickson (2004), who developed …

Minority Parents' Narratives Of Living With Their Child With An Autism Spectrum Disorder, Monique Willis

Loma Linda University Electronic Theses, Dissertations & Projects

Previous studies addressing the impact of autism spectrum disorder (ASD) on the family focus largely on the Caucasian population (Cassidy, McConkey, Truesdale-Kennedy, & Slevin, 2008; Hebert & Koulouglioti, 2010; N. Johnson, Frenn, Feetham, & Simpson, 2011; Myers, Mackintosh, & Goin-Kochel, 2009; Rao & Beidel, 2009). There is a dearth of research examining the impact of ASD on family dynamics in marginal groups. This study attempts to add to the sparse literature and to increase understanding of the specific experiences of minority parents of children with ASD. Family systems theory, family systems-illness model, and social constructivism frameworks inform this study and …

The Effects Of Appearance-Based Reality Shows On Body Image, Amanda F. Suplee

Loma Linda University Electronic Theses, Dissertations & Projects

Media seems to play the largest role in transmitting messages regarding societal standards of attractiveness; especially in reinforcing the thin ideal for females. There is strong evidence indicating that females who are more likely to make appearance comparisons with thin images in the media often experience negative outcomes. Research has shown that increased exposure to thin images in the media is associated with higher body dissatisfaction and eating disorder features. A form of media that has been given little research attention is reality television, specifically appearance-based reality television. The current study examined the effects of viewership of appearance-based reality television …

Effects Of Proton Radiation On Behavior In A Mouse Model Of Alzheimer’S Disease, John A. Bellone

Loma Linda University Electronic Theses, Dissertations & Projects

Astronauts venturing outside Earth’s magnetosphere risk exposure to charged particle radiation that has been shown to cause neurological deficits in rodents via oxidative stress, neuroinflammation, altered neurogenesis, and synaptic changes. Since these responses are similar to those observed in age-related neurodegenerative diseases, we hypothesized that individuals with a propensity toward developing Alzheimer’s disease (AD) would be more adversely affected by such exposure. To test this hypothesis, we exposed young double transgenic APP/PSEN1 mice (a commercially available strain engineered to develop AD-like neuropathology) and their wild-type (non-transgenic) counterparts to low doses of 150 MeV proton particle radiation and assessed the effects …

De Novo Assembly Of The Common Marmoset Transcriptome From Nextgen Mrna Sequences, Mnirnal D. Maudhoo, Dongren Ren, Julien S. Gradnigo, Robert M. Gibbs, Austin C. Lubker, Etsuko N. Moriyama, Jeffrey French, Robert B. Norgren

Psychology Faculty Publications

Background: Nonhuman primates are important for both biomedical studies and understanding human evolution. Although research in these areas has mostly focused on Old World primates, such as the rhesus macaque, the common marmoset (Callithrix jacchus), a New World primate, offers important advantages in comparison to other primates, such as an accelerated lifespan. To conduct Next Generation expression studies or to study primate evolution, a high quality annotation of the marmoset genome is required. The availability of marmoset transcriptome data from five tissues, including both raw sequences and assembled transcripts, will aid in the annotation of the newly …

Female Mating Adaptations: Salient Features And The Influence Of Fertility Status, Katherine Melton

Modern Psychological Studies

Modern human beings share the adaptive mating strategies of their ancestral predecessors, even though the adaptive environment is a relic of the past. Due to the large parental investment mammalian females must contribute in order to reproduce, women face unique challenges in their quest for reproductive fitness. This review endeavors to address behavioral, strategic, and perceptual shifts in female mating adaptations within the context of the menstrual cycle in order to yield a greater understanding of modern women and the evolutionary basis for behavior.

Why Primate Models Matter, Kimberley A. Phillips, K. L. Bales, J. P. Capitanio, A. Conley, P. W. Czoty, B. A. 'T Hart, William D. Hopkins, S.L. Hu, L. A. Miller, M. A. Nader, P. W. Nathanielsz, J. Rogers, C. A. Shively, M.L. Voytko

Psychology Faculty Research

Research involving nonhuman primates (NHPs) has played a vital role in many of the medical and scientific advances of the past century. NHPs are used because of their similarity to humans in physiology, neuroanatomy, reproduction, development, cognition, and social complexity – yet it is these very similarities that make the use of NHPs in biomedical research a considered decision. As primate researchers, we feel an obligation and responsibility to present the facts concerning why primates are used in various areas of biomedical research. Recent decisions in the United States, including the phasing out of chimpanzees in research by the National …

The Relationship Between Traumagenic Dynamic Responses Towards Childhood Sexual Abuse, Ethnic Identity, Social Support, Trauma Severity, And Attitudes Towards Interpersonal Relationships In Adolescent Females, Nita J. Makhija

Seton Hall University Dissertations and Theses (ETDs)

This study used the theory of traumagenic dynamics (TD) to examine how symptomatology resulting childhood sexual abuse (CSA) are related to the attitudes adolescent females have towards interpersonal relationships. The ultimate goal being that this understanding can inform the creation and implementation of empirically based clinical interventions that specifically target CSA-related symptoms which are associated with the endorsement of unhealthy attitudes towards romantic relationships. In examining this relationship, family support and ethnic identity were examined as protective factors against the endorsement of unhealthy attitudes towards romantic relationships, and trauma severity and the presence of domestic violence in the home were …

The Effects Of Room Color On Stress Perception: Red Versus Green Environments, Teresa M. Kutchma

Journal of Undergraduate Research at Minnesota State University, Mankato

The purpose of the study was to investigate the effects of red versus green room colors on individual perception of stress. Room color was found through previous studies to have specific effects on psychomotor activity and emotional states. Correlations were found between red room color and emotional and physical stimulation, while green was associated with inhibitory effects. Additionally, Goldstein’s theory of color perception showed that red has stimulating effects on human behavior. Subjects consisted of 15 female and 15 male college freshmen at Minnesota State University, Mankato. An experimental booth was used for red, green and white room conditions. Subjects …

Distinguishing Observed Inattentive Behaviors In The College Classroom As They Correlate To Brain Wave Activity Utilizing A Wireless Electroencephalograph, Christopher J. Aura, Matthew R. Stanton

Journal of Undergraduate Research at Minnesota State University, Mankato

A significant amount of research has been devoted to the behavioral correlates of inattention in children (A.P.A., 2000; Arnold, 2000; Gordon & Barkley, 1998). It is proposed by the authors that college students, in their several years of experience, are much more capable of masking these trademark behaviors. When a child loses interest they will begin to openly look around the room, shift in their seat, or chat with their neighbors (Sandberg, Rutter & Taylor, 1978; Arnold, 2000). College students however, are proposed to candidly fidget, shift in their seat, or even maintain eye contact with their instructor while “daydreaming”. …

Pupil Dilation Dynamics Track Attention To High-Level Information, Olivia E. Kang, Katherine E. Huffer, Thalia P. Wheatley

Dartmouth Scholarship

It has long been thought that the eyes index the inner workings of the mind. Consistent with this intuition, empirical research has demonstrated that pupils dilate as a consequence of attentional effort. Recently, Smallwood et al. (2011) demonstrated that pupil dilations not only provide an index of overall attentional effort, but are time-locked to stimulus changes during attention (but not during mind-wandering). This finding suggests that pupil dilations afford a dynamic readout of conscious information processing. However, because stimulus onsets in their study involved shifts in luminance as well as information, they could not determine whether this coupling of stimulus …

I continued in an area I began as an undergraduate student of medical anthropology and explored the systems that interact to influence mental health of …

The Basis Of Self And Other In Gender Constructed Identity, Julie L. Lemley

Journal of Undergraduate Research at Minnesota State University, Mankato

This paper is an extension of previous research projects wherein I applied theories of identity and labeling (Garfinkle), power (French and Raven) and gender (Pearson, West and Turner) to adolescent girls’ identity construction. Using methods of textual criticism, I argued then that the advertising targeting adolescent girls at the crucial transitional period between child identity and adult identity was dominated by patriarchal imagery, the implications of which are sexual violence, low-self esteem and self-objectification by young women. This paper applies the same methodology but to identity formation of adolescent boys, arguing on the basis of Hegel’s master-slave dialectic that adolescent …

Asperger's Disorder In Older Adulthood: The Unique Treatment Concerns And Implications For Applying Cognitive Behavioral Therapy, Brian Beaumund

Graduate School of Professional Psychology: Doctoral Papers and Masters Projects

This article provides a theoretical consideration for the problems faced by older adults diagnosed with Asperger’s Disorder as well as implications for applying Cognitive Behavioral Therapy with this distinct population. The author presents the relevant literature concerning the unique presentation and common problems of each, traditionally distinct population: (a) older adults and (b) Asperger’s Disorder. The author then extrapolates this data into a theoretical conceptualization of the unique clinical presentation and treatment considerations for the underrepresented population of older adults with Asperger’s Disorder. The author then presents a review of the relevant literature concerning the application of Cognitive Behavioral Therapy …

The Psychological Well-Being Of Divorced Fathers: A Theoretical Model And Projection, Todd Lawrence Bottom

College of Science and Health Theses and Dissertations

The U.S. divorce rate increased substantially from WWII until the 1980's. Although the number of divorces decreased marginally in the past decade, the number of marriages also decreased, causing the divorce rate to remain nearly unchanged from 2000 to 2010. The most frequently cited negative effect of divorce and separation is perhaps the loss of father-child contact, although little research was dedicated to understanding the post-divorce outcomes of fathers - especially with regard to their long-term outcomes. The present study assessed how several factors (e.g. parenting decisions, custody status, parenting efficacy, and parenting encouragement) influenced divorced fathers' psychological well-being. Results …

Examining The Pathway From Maternal Criminal Involvement To Adolescent Delinquency, Dina Chavira

College of Science and Health Theses and Dissertations

As incarceration rates across the United States have continued to rise, there has been growing concern with the unintended consequences that have resulted. This has prompted researchers across multiple disciplines to study the effects of incarceration at the individual, family, community, and societal levels. An important but overlooked factor pertains to extensive multiple social service agency involvement and missed opportunities for intervention. Families involved with the criminal justice system (CJS) are often at risk of involvement with other human service agencies, one agency being the child welfare system (CWS). Little is known about families who fall within these two systems, …

Sexy But Not Sexual: An Examination Of The Sexual Narratives Of African American Adolescent Females, April Timmons

College of Science and Health Theses and Dissertations

Much of the research on sexuality during adolescence has focused on the potential negative sequelae of adolescent sexual behavior such as STI acquisition or teenage pregnancy. Researchers have begun to advocate for examining adolescent sexuality as a normative aspect of adolescent development. One aspect of this examination would be to form a more complete understanding of how adolescents develop their sexual identity – their conceptualization of themselves as a sexual being. Erickson’s (1968) identity development theory asserts that identity is developed internally and shaped by the social environment.

Development of a healthy sexual identity may be particularly difficult for African …

The Effect Of Parent-Child Interaction Therapy On Strengthening The Attachment Relationship With Foster Parents And Children In Foster Care, Christina Marie Danko

College of Science and Health Theses and Dissertations

Children in foster care are more likely to face difficulties in forming a secure attachment relationship and to have problem behaviors than children not in foster care (Dozier & Rutter, 2008). Parent-Child Interaction Therapy (PCIT) is an evidence-based treatment that focuses on strengthening the attachment relationship between the child and the caregiver, as well as reducing the number and intensity of behavior problems. Although PCIT is based on attachment theory, very few studies have examined the effect of PCIT on child-parent attachment or examined the effect of PCIT on attachment in foster care families. This study extends prior work and …

Network Organization Unfolds Over Time During Periods Of Anxious Anticipation, Brenton Mcmenamin, Sandra Langeslag, Mihai Sirbu, Srikanth Padmala, Luiz Pessoa

Psychology Faculty Works

Entering a state of anxious anticipation triggers widespread changes across large-scale networks in the brain. The temporal aspects of this transition into an anxious state are poorly understood. To address this question, an instructed threat of shock paradigm was used while recording functional MRI in humans to measure how activation and functional connectivity change over time across the salience, executive, and task-negative networks and how they interact with key regions implicated in emotional processing; the amygdala and bed nucleus of the stria terminalis (BNST). Transitions into threat blocks were associated with transient responses in regions of the salience network and …

The Influence A Digital Screen Has On The Learning Process, For Students With Autism Spectrum Disorder, George Gordon

Theses and Dissertations

The purpose of this study was to explore the effect a digital screen (iPad) had on the learning process, of a vocabulary matching activity, of words to definitions activity, in a student with autism spectrum disorder, in comparison to learning on paper (flashcards). According to past research, digital based interventions are utilized more often in research settings, indicating a growth in its use in educational settings (Goldsmith & LeBlanc, 2004). Individuals with autism spectrum disorder are often given interventions using digital screen based technologies, in academic and other life and skill teaching settings (Ferguson, Myles, & Hagiwara, 2005; Gentry, Wallece, …

The Effects Of Divorce And Its Associated Stressors On Children And Adolescents, Aaron Brownlee

Journal of Undergraduate Research at Minnesota State University, Mankato

Four factors were looked at to determine how children of divorce are affected by their parents divorce. The Family Environment Scale (FES) assessed family environment, Social Support Scale for children (SSSC) assessed social support, and the Life Events Checklist (LEC) assessed appraisal of the stressors shown to co-occur with divorce. The Behavioral Assessment Scale for Children, second edition (BASC-2; parent and self-reports) measured the criterion of this study, behavioral and emotional functioning. The sample consisted of 91 children and their parents from the Mankato area public schools. Hierarchical multiple regressions indicated a main effect of the appraisal of co-occurring stressors …

Cluster B Personality Disorders Separated By Gender Expectations, Brianna Kloss

Journal of Undergraduate Research at Minnesota State University, Mankato

Criticisms of the Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.; DSM-IV-TR; American Psychiatric Association [APA], 2000), the most widely recognized system for classification of psychological disorders in the U.S., including gender discriminating disorders and diagnoses, have existed for all editions of the DSM. Arguably, gender construction has a profound influence on the standards and evaluation of normal and abnormal behaviors. Concern for the presence of gender bias of personality disorders has been raised within the DSM, in part, by the frequent diagnoses made according to gender stereotypes. The DSM-IV-TR characterizes personality disorders as marked distress and …

Bursts And Heavy Tails In Temporal And Sequential Dynamics Of Foraging Decisions, Kanghoon Jung, Hyeran Jang, Jerald D. D. Kralik, Jaeseung Jeong

Dartmouth Scholarship

A fundamental understanding of behavior requires predicting when and what an individual will choose. However, the actual temporal and sequential dynamics of successive choices made among multiple alternatives remain unclear. In the current study, we tested the hypothesis that there is a general bursting property in both the timing and sequential patterns of foraging decisions. We conducted a foraging experiment in which rats chose among four different foods over a continuous two-week time period. Regarding when choices were made, we found bursts of rapidly occurring actions, separated by time-varying inactive periods, partially based on a circadian rhythm. Regarding what was …

Sexual Education And Attitudes Toward Masturbation, Jannine Ray, Shelby Afflerbach

Journal of Undergraduate Research at Minnesota State University, Mankato

The long-standing social stigma surrounding masturbation has led to its prohibition from being included in public school curriculum as a healthy sexual practice. Furthermore, not only is masturbation a healthy sexual practice for the individual, research has demonstrated masturbation to be helpful in treating sexual dysfunctions for couples. Therefore, if the topic of masturbation is included in comprehensive sexual education as a healthy sexual practice, it may promote sexual health among individuals both intra- and interpersonally. The present study recruited from a convenient sample from a medium sized state university in the upper Midwest. Participants completed two surveys, administered through …
