Is Aggression In The Eye Of The Beholder?: An Eye-Tracking Study, Kemar P. Pickering Jun 2024

Is Aggression In The Eye Of The Beholder?: An Eye-Tracking Study, Kemar P. Pickering

Dissertations, Theses, and Capstone Projects

The study of aggression offers opportunities to more deeply understand criminal behavior, personality and temperament. A deeper understanding of aggression has many implications in applied settings, including work, education and health. The knowledge gained may improve the treatment of behavioral misconduct and antisocial behavior. Additionally, the study of aggression has the potential to inform assessments of quality of life and development while offering information to guide early intervention and improve behavior trajectories.

Understanding aggression has many real-world applications, such as creating a better understanding of criminal activity, identifying who might be more likely to become a criminal, allowing for early …


A Process Model Of Workplace Cyber Incivility Spillover, Cora Hurt May 2024

A Process Model Of Workplace Cyber Incivility Spillover, Cora Hurt

Masters Theses & Specialist Projects

Cyber incivility is a pervasive problem, affecting individuals not only while at work but also at home. It has been found to spillover to the home domain in the form of aggression and withdrawal, affecting the target and their partner, but the mechanism behind this association has not been examined. This study examines work-related affective rumination as a spillover mechanism between experienced cyber incivility and aggressive and withdrawn behaviors at home. I hypothesized that daily experienced cyber incivility will be positively associated with both aggressive behavior and withdrawn behavior at home, and work-related affective rumination will mediate this relationship. Using …


Perceptions Of Violent Content And Their Relationships On Aggressive Behavior: The Effects Of Implicit Beliefs On Aggression In Relation To Video Content, Logan Mccombs Apr 2024

Perceptions Of Violent Content And Their Relationships On Aggressive Behavior: The Effects Of Implicit Beliefs On Aggression In Relation To Video Content, Logan Mccombs

Theses and Dissertations

Previous research shows that consuming violent media can lead to increased aggression in thoughts, feelings, and behaviors. Several other factors also contribute to such behaviors but have not been thoroughly studied including implicit beliefs about aggression in relation to media content. This two-part study consists of (1) an exploratory iterated principal-factor method to create an implicit belief measure about consuming violent media in conjunction with correlational analyses and (2) between subjects hierarchical linear regression models to determine what effects implicit beliefs have on subsequent aggression after participants view either a violent of nonviolent video, while controlling for violent media consumption …


Seeing Red: Hostile Attribution Bias, Aggression, And Antisocial Personality Disorder Traits, Kaley Potter Jan 2024

Seeing Red: Hostile Attribution Bias, Aggression, And Antisocial Personality Disorder Traits, Kaley Potter

Graduate Theses, Dissertations, and Problem Reports

Antisocial personality disorder (ASPD) is a destructive and severe mental illness that costs the U.S. trillions of dollars annually. Although ASPD is significantly correlated with acts of aggression, violence, and imprisonment, not all individuals with ASPD are aggressive. In samples without ASPD, increased aggression has been linked to an error in social information processing, which is referred to as hostile attribution bias (HAB).

The current study tested the extent to which HABs, or the tendency to attribute hostility to neutral or ambiguous stimuli, predicted aggression above and beyond ASPD traits in participants with a history of incarceration. Participants (N = …


The Use Of Problematic Behaviors As Predictors Of Suicidal Ideations And Attempts In Adolescent Psychiatric Inpatients, Jessica Lamont-George Jan 2024

The Use Of Problematic Behaviors As Predictors Of Suicidal Ideations And Attempts In Adolescent Psychiatric Inpatients, Jessica Lamont-George

PCOM Psychology Dissertations

Suicidality is a health concern among adolescents. Approximately, one million people attempt suicide each year and it is the second leading cause of death for those aged 10 to 19. Inpatient hospitalizations may be beneficial for individuals who pose a danger to themselves or others since it provides a safe environment for the individual to receive individualized care. Many individuals who have been admitted for psychiatric inpatient hospitalization have suicidal ideations or attempts. The Child and Adolescent Behavior Assessment-Youth Scale (CABA-Y) explores an individual’s stressors and problem behaviors that may be contributing to the reasons for hospitalization. While inpatient, some …


Returning To School After Covid-19: Relationships Between Parental Stress And Resilience With Children’S Mental Health Behaviors, Christa P. Stanley Sep 2023

Returning To School After Covid-19: Relationships Between Parental Stress And Resilience With Children’S Mental Health Behaviors, Christa P. Stanley

Doctoral Dissertations and Projects

During the COVID-19 lockdowns, experts predicted an increase of children’s mental health issues. However, not all children showed symptoms after lockdowns lifted. The study’s purpose was to examine parental stress and resilience during COVID-19 lockdowns and their relationship to children’s behaviors, specifically anxiety and aggression after lockdown. Participants included 61 parents of children currently aged 7-11 who did not have mental health disorders before COVID lockdowns. Most parents were white, non-Hispanic within middle to high income ranges. The quantitative study used a correlational design. Parents were recruited through school websites and social media sites which linked them to a 122-question …


You Hurt My Feelings: Autonomic And Behavioral Responses To Social Exclusion And The Moderating Effect Of Psychopathic Traits, Liat Kofler Sep 2023

You Hurt My Feelings: Autonomic And Behavioral Responses To Social Exclusion And The Moderating Effect Of Psychopathic Traits, Liat Kofler

Dissertations, Theses, and Capstone Projects

Humans have a fundamental need to form and maintain social connections, and thus experiencing social exclusion is extremely distressing as it threatens this basic human need. Individuals who are socially excluded often respond aggressively, not only towards their ostracizers but also towards innocent bystanders, with ostracism being implicated in extreme acts of violence such as school shootings. However, individual differences in behavior exist within the context of social exclusion as not everyone responds aggressively after being ostracized. Identifying risk factors for retaliatory aggressive behavior following experiences of social exclusion may facilitate the development of targeted interventions aimed at mitigating such …


The Role Of Trait Mindfulness, Perceived Stress, And Impulsivity In Understanding The Relationship Between Stress Mindset And Psychological Intimate Partner Aggression, Sarah Joyanna Johnson Aug 2023

The Role Of Trait Mindfulness, Perceived Stress, And Impulsivity In Understanding The Relationship Between Stress Mindset And Psychological Intimate Partner Aggression, Sarah Joyanna Johnson

Doctoral Dissertations

Perpetration of psychological intimate partner aggression is a pervasive health issue and has been estimated to occur in 60 to 90 percent of relationships. Effects of intimate partner violence on its victims has been demonstrated to have lasting physical and mental health issues. Psychological intimate partner aggression has been demonstrated to have particularly harmful effects, above and beyond those identified in physical intimate partner aggression. Psychological intimate partner aggression has been demonstrated to be impacted by impulsivity, stress-mindset, perceived stress, and mindfulness. The present study proposed to examine a path analysis model of the relation between stress-mindset and psychological intimate …


Neuropsychiatric Sequelae Of Traumatic Brain Injury: The Impact Of Aggression And Self-Perception On The Quality Of Life Of The Traumatic Brain Injury Survivors, Aida Bazarganpour May 2023

Neuropsychiatric Sequelae Of Traumatic Brain Injury: The Impact Of Aggression And Self-Perception On The Quality Of Life Of The Traumatic Brain Injury Survivors, Aida Bazarganpour

Doctoral Dissertations and Projects

The occurrence of neuropsychiatric sequelae is frequently observed among survivors of traumatic brain injury (TBI). These neuropsychiatric sequelae can characterize the quality of life of TBI survivors. Among these neuropsychiatric conditions, aggression and self-perception are significant because of their potential to impair survivors’ well-being. Long-term social isolation, common among TBI survivors, has also been linked with an increased likelihood of aggressive behavior. However, research investigating the effects of aggression and self-perception on quality of life of TBI survivors is limited. Thus, the purpose of this study was to explore the relationships connecting aggression and self-perception with quality of life of …


Trait Sadism In Bdsm Practitioners And Non-Practitioners, Marley Russell Apr 2023

Trait Sadism In Bdsm Practitioners And Non-Practitioners, Marley Russell

Psychology ETDs

Sadism is an elusive construct within psychology. Multiple types are studied without clear psychometric or theoretical distinctions, and operationalizations of these respective sub-constructs lack validity. This study explores the empirical distinction between two sadism types: consensual sexual sadism (i.e. in the context of BDSM) and trait sadism. Trait sadism is widely synonymized with “everyday sadism”, but here conceptualized as a higher-order construct encompassing both everyday and a novel “prosocial sadism”. I develop and pilot the BDSM Identities and Behaviors (BIB) checklist in a sample of BDSM practitioners. I then compare those practitioners to non-practitioners on trait sadism and dark triad …


The Relationship Between Perfectionism And Aggression In Collegiate Athletes, Mia Colucci Apr 2023

The Relationship Between Perfectionism And Aggression In Collegiate Athletes, Mia Colucci

Honors College Theses

The traits of perfectionism and aggression in modern society are pervasive. Negative effects of both perfectionistic and aggressive behavior are well-documented, including increased risk of mental illness, such as anxiety, depression, and eating disorders (Wade & Tiggeman, 2013; Wheeler et al., 2011; Chung et al., 2019; Koivula et al., 2002). Perfectionism and aggression are traits seen independently in collegiate athletes and are relevant traits when assessing an athletes psychological profile. While the two traits have been linked previously in the general population (Chester, 2015), little research exists to link the two in collegiate athletes. This study’s purpose is to discover …

Who Is Leading Today’S Family? The Detrimental Effects Of An Absent Father, Kimberly J. Davis Mar 2023

Who Is Leading Today’S Family? The Detrimental Effects Of An Absent Father, Kimberly J. Davis

Doctoral Dissertations and Projects

Fathers have an enormous role in their families – it was God’s original design. This study considered the detrimental effects of a physically absent father as the leader, mentor, disciplinarian, and husband of the family home, using a quantitative research design. The theoretical framework used for this descriptive design was John Bowlby’s attachment theory, Dr. Murray Bowen’s family systems theory, Daniel Goleman’s psychological theory on emotional intelligence, and, last, Albert Bandura’s view on aggression theory and the General Aggression Model (GAM). Additionally, the concept of father hunger was explored and measured as this was a crucial construct during this study. …


Examining The Moderating Role Of Executive Functioning On Flooding And Intimate Partner Violence, Gabriella Damewood Jan 2023

Examining The Moderating Role Of Executive Functioning On Flooding And Intimate Partner Violence, Gabriella Damewood

Theses and Dissertations

Intimate partner violence (IPV) is highly prevalent, so much so that it has been described as a global public health crisis. Therefore, it is important to elucidate what conditions increase risk for IPV to better understand its etiology. Research emphasizing dyadic and self-regulatory processes may shed light on what differentiates those who perpetrate IPV. Specifically, both emotional flooding and executive functioning (EF) deficits have been implicated with IPV, but it is unclear how these variables may interact in predicting dating aggression. The current study explored how emotional flooding may differentially amplify risk for IPV under varying levels of executive functioning …


When Crying Turns To Hitting: Examining Maternal Responses To Negative Affect, Brooke Edelman Jan 2023

When Crying Turns To Hitting: Examining Maternal Responses To Negative Affect, Brooke Edelman

Theses and Dissertations

Most children exhibit some form of physical aggression in the first years of life, and physical aggression is particularly common in toddlerhood (Hay, 2005; Lorber et al., 2017; Lorber et al., 2019; Nærde et al., 2014; Tremblay & Nagin, 2005). Further, aggression is conceptualized as a byproduct of frustration and related negative affect (Berkowitz, 1989), and early physical aggression is empirically linked to anger (Lorber et al., 2015). The current study is part of a body of research examining early aggression and will explore the mechanisms by which children’s negative affect escalates to aggression in a brief conflict episode. Given …


Aggression, Avoidance, Shame And Narcissism In Fragile Masculinity, Israel Zev Meth Jan 2023

Aggression, Avoidance, Shame And Narcissism In Fragile Masculinity, Israel Zev Meth

Selected Full-Text Dissertations 2020-

The overwhelming representation of males in physically aggressive acts and violent crime suggests that masculinity contributes to the gender discrepancy. Fragile masculinity, a term denoting the cultural mandate and the individual’s perception that manhood is precarious, has been posited as particularly meaningful in understanding the etiology of aggression and relational avoidance in men. Empirical work suggests that there is a link among these constructs (Vandello, 2013), but the literature has not fully explored variables that may inform or impact these connections. Based on psychodynamic theories of narcissism, shame and aggression, this study aimed to empirically test their impact. Mediation and …


Witnessing Community Violence And Its Consequences: Changes Across Middle School, Sarah Pittman Jan 2023

Witnessing Community Violence And Its Consequences: Changes Across Middle School, Sarah Pittman

Theses and Dissertations

Community violence exposure is prevalent among youth residing in economically marginalized communities that have high rates of violence. Witnessing community violence has been concurrently associated with persistent adverse consequences. However, few studies have applied a developmental psychopathology framework and examined dynamic developmental processes between witnessing community violence and outcomes over time. Moreover, most prior studies have used analyses that assume that associations between witnessing violence and outcomes are the same for all adolescents, which is inconsistent with both developmental theories and theories specific to community violence exposure. The goal of this study was to apply a developmental psychopathological framework to …


Exploring Relationships Between Dog Training Approaches And Aggression, Fear, And Dog-Owner Relationship, Janee Wise Dec 2022

Exploring Relationships Between Dog Training Approaches And Aggression, Fear, And Dog-Owner Relationship, Janee Wise

Theses and Dissertations

Abstract

The current study examined relationships between operant conditioning derived dog training techniques and aggression, fear, and dog-owner relationship. Participants (N = 326) completed two online surveys; 1) a survey created for this study measuring the frequency of use of 14 common dog training techniques, which were grouped into four categories based upon operant conditioning: positive reinforcement, negative punishment, positive punishment, and negative reinforcement and 2) the Canine Behavioral Assessment and Research Questionnaire (C-BARQ), which measured several factors related to dog behavior. There were no statistically significant results related to the use of positive reinforcement or positive punishment. However, dog …


What’S Sparking The Madness? Exploration Of Social Media Possibly Influencing Aggression Amongst Online Users, Tia Porterfield Dec 2022

What’S Sparking The Madness? Exploration Of Social Media Possibly Influencing Aggression Amongst Online Users, Tia Porterfield

Doctoral Dissertations and Projects

The purpose of this dissertation is to address the research gap regarding social media platforms having a possible influence when provoking experiences of internal (i.e., emotions/feelings and cognitions) and/or external (i.e., behaviors) forms of aggression and problematic internet use in their online community members. A brief examination of the aggression-frustration hypothesis will construct a foundational theoretical framework of the emotional and behavioral processes that may occur in users while utilizing their preferred social media platform. Recent peer- reviewed literature will be examined to highlight the existing research gap. The present study will attempt to explore possible explanations behind users’ motives …


Disentangling Instrumental And Reactive Aggression In The Competitive Reaction Time Task And Their Associations With Factors Of Meanness In Psychopathy, Ashley Michelle Poston Dec 2022

Disentangling Instrumental And Reactive Aggression In The Competitive Reaction Time Task And Their Associations With Factors Of Meanness In Psychopathy, Ashley Michelle Poston

UNLV Theses, Dissertations, Professional Papers, and Capstones

Aggression is often subtyped into reactive and instrumental aggression. Reactive aggression occurs in response to some form of provocation and is often accompanied by anger. Instrumental aggression is not provoked and is relatively unemotional. Existing aggression paradigms primarily measure reactive aggression, and the laboratory measurement of instrumental aggression has proved challenging. This study modified the competitive reaction time task to include an entire block of instrumental aggression trials, in addition to the standard block of reactive trials, in effort to create a single paradigm within which both reactive and instrumental aggression can be measured in the laboratory. Psychopathy is a …

Positive And Negative Actions Early In The Relationship Predict Later Interactions Among Toddlers, Ayelet Lahat, Zhangling Lou, Michal Perlman, Nina Howe, Jonathan Santo, Holly E. Recchia, William M. Bukowski, Hildy S. Ross

Psychology Faculty Publications

Very little is known about the role of early interactions in the development of peer relationships among toddlers. The present study examined whether behaviors early in the formation of toddler relationships predict interactions later in their relationships. Twenty-eight unfamiliar 20- and 30-month-old toddlers from a predominately European background met separately with each of two other toddlers for 18 playdates. Both positive and negative behaviors at the beginning of the relationship predicted a higher frequency of games later in the relationship. Positive behaviors at the beginning of the relationship predicted fewer conflicts later in the relationship. Negative behaviors at the beginning …

A Pilot Feasibility Trial Of Mindfulness And Modification Therapy For Males Who Use Aggression, Jenny Mitchell Sep 2022

A Pilot Feasibility Trial Of Mindfulness And Modification Therapy For Males Who Use Aggression, Jenny Mitchell

Dissertations, Theses, and Capstone Projects

Physical aggression incurs substantial harm to victims and witnesses, particularly when it occurs within close relationships such as family, friendships, or intimate partnerships. Men who use aggression against partners and other adults frequently experience high levels of psychopathology, including depression, posttraumatic stress symptoms, anxious/insecure attachment, paranoia, bipolar disorder, intermittent explosive disorder, personality disorders, and substance abuse, which contribute to use of aggressive behaviors. However, existing treatments for aggression often do not address these symptoms. It is important that treatments for aggression are grounded in theoretical literature and backed by empirical support in order to increase treatment engagement and effectiveness. Treatments …


Aggression In Session: Defining, Conceptualizing, And Treating Aggression, Tyler A. Greenough May 2022

Aggression In Session: Defining, Conceptualizing, And Treating Aggression, Tyler A. Greenough

Educational Specialist, 2020-current

Within the counseling profession, there is a great deal of interaction with aggression affecting both clients and the systems affecting clients. Therefore, it is vital that counselors be adequately prepared to work with various presentations of aggressive behavior. Aggression is defined, categorized based on common historical delineations, and summarized from a multi-axis continuum perspective. Contextual factors are considered such as the role of hormones, neurotransmitters, varying substances, and a wide range of diagnoses. Aggression is then conceptualized from a functional lens and explored based upon a need fulfillment model. Treatment practices such as building self-esteem, increasing emotional regulation, and developing …


Participation In Collision, Contact, And Noncontact Sports And Academic Outcomes At A United States Service Academy, Benjamin Thomas Showman May 2022

Participation In Collision, Contact, And Noncontact Sports And Academic Outcomes At A United States Service Academy, Benjamin Thomas Showman

Doctoral Dissertations and Projects

The present study seeks to determine whether significant differences exist in the academic outcomes, specifically grade point averages (GPA), between college students who participate in collision, contact, or noncontact sports. Additionally, this study seeks to understand whether sport contact levels are predictive of a student’s GPA when sport competition levels and demographic variables are also taken into account. Current research suggests links between sports participation, aggression, brain injuries, and academic outcomes. Along these lines, a significant amount of research has investigated relationships between student aggression and academic outcomes, between aggression and sport contact levels, and between sports participation and academic …


Naked Mole-Rat Social Phenotypes Vary In Investigative And Aggressive Behavior In A Laboratory Partner Preference Paradigm, Ilapreet Toor, Rashoun Maynard, Xinye Peng, Annaliese K. Beery, Melissa M. Holmes Apr 2022

Naked Mole-Rat Social Phenotypes Vary In Investigative And Aggressive Behavior In A Laboratory Partner Preference Paradigm, Ilapreet Toor, Rashoun Maynard, Xinye Peng, Annaliese K. Beery, Melissa M. Holmes

Psychology: Faculty Publications

Here we employed the partner preference test (PPT) to examine how naked mole-rat non-breeding individuals of different behavioral phenotypes make social decisions. Naked mole-rats from six colonies were classified into three behavioral phenotypes (soldiers, dispersers, and workers) using a battery of behavioral tests. They then participated in a 3 h long PPT, where they could freely interact with a tethered familiar or tethered unfamiliar conspecific. By comparing the three behavioral phenotypes, we tested the hypothesis that the PPT can be used to interrogate social decision-making in this species, revealing individual differences in behavior that are consistent with discrete social phenotypes. …


Political Attitudes, Outward Aggression, And Self-Directed Violence, Christopher Holloway Apr 2022

Political Attitudes, Outward Aggression, And Self-Directed Violence, Christopher Holloway

Thinking Matters Symposium

Violence has increased at political events and marches in the last several years, particularly during the Trump presidency and marked by the January 6 attack on the U.S. Capitol. Research has been conducted on approval of political violence, but little is known about political attitudes and how they relate to the likelihood of engaging in everyday generalized violence. Furthermore, violence against others and violence against the self, such as suicide, are usually treated and studied separately. This study hopes to identify what relationships, if any, exist between political attitudes and violence, both outward and self-directed. Participants (N = 153) completed …

The Hostility Syndrome As A Profile Differentiating Football Spectators, Karol Gorner, Janusz Zielinski, Adam Jurczak

Baltic Journal of Health and Physical Activity

Background: Football matches may be entertaining, or may become events erupting with violence and releasing aggression. Unfortunately, incidents of hooligans’ disorderly conduct during matches and outside the stadium are more and more frequently considered to be prevailing and unavoidable elements in football games. Material/Methods: The study comprised a total of 60 football hooligans and 60 ordinary football fans, in which the hostility syndrome was assessed by means of the Scale of Interpersonal Stances (SIS). Results: The results of the survey regarding the style of social functioning in the groups of respondents showed a significant difference (p = 0.004) between them. …


Selectivity And Sociality: Aggression And Affiliation Shape Vole Social Relationships, Nicole S. Lee, Annaliese K. Beery Mar 2022

Selectivity And Sociality: Aggression And Affiliation Shape Vole Social Relationships, Nicole S. Lee, Annaliese K. Beery

Psychology: Faculty Publications

The formation of selective social relationships is not a requirement of group living; sociality can be supported by motivation for social interaction in the absence of preferences for specific individuals, and by tolerance in place of social motivation. For species that form selective social relationships, these can be maintained by preference for familiar partners, as well as by avoidance of or aggression toward individuals outside of the social bond. In this review, we explore the roles that aggression, motivation, and tolerance play in the maintenance of selective affiliation. We focus on prairie voles (Microtus ochrogaster) and meadow voles (Microtus pennsylvanicus) …
