Explaining Incivility In The Workplace: The Effects Of Personality And Culture, Wu Liu, Shu-Cheng Chi, Ray Friedman, Ming-Hong Tsai

Research Collection School of Social Sciences

This study examines individual and cultural antecedents of incivility in the workplace, using a sample of MBAs and EMBAs from Taiwan and the United States. We predicted that individual achievement orientation would enhance incivility, based on Dollard’s frustration aggression hypothesis, and that those who were higher in direct conflict self-efficacy (i.e., beliefs in one's skills in managing direct conflict) would be higher in incivility. These predictions were supported. We also predicted, and found, that collectivism orientation constrains these main effects, so that for those high in collectivism, the impact of achievement orientation and direct conflict self-efficacy is weak or nonexistent. …

A Pilot Study To Explore The Use Of Expressive Writing To Reduce Anxiety And Psychological Threat In An Academic Setting, Cynthia Delores Jenkins

Counseling & Human Services Theses & Dissertations

The purpose of this study was to investigate if the use of Pennebaker's short-term expressive writing intervention would have a positive effect on the academic performance of a group of third semester underperforming freshmen. This is a relatively brief and simple intervention pioneered by J. W. Pennebaker (1997) who conducted numerous studies using the procedure. Most of the research has involved having subjects write about traumatic, stressful or emotional events for 15–20 minutes (the maximum) over 3–5 days. In contrast, the studies by Wilson (2006) and Cohen et al (2006) used self-affirmations for writing. For this study self-affirmation directions were …

To See Or Not To See: Prestimulus Α Phase Predicts Visual Awareness, Kyle E. Mathewson, Gabriele Gratton, Monica Fabiani, Diane M. Beck, Tony Ro

Publications and Research

We often fail to see something that at other times is readily detectable. Because the visual stimulus itself is unchanged, this variability in conscious awareness is likely related to changes in the brain. Here we show that the phase of EEG α rhythm measured over posterior brain regions can reliably predict both subsequent visual detection and stimulus-elicited cortical activation levels in a metacontrast masking paradigm. When a visual target presentation coincides with the trough of an α wave, cortical activation is suppressed as early as 100 ms after stimulus onset, and observers are less likely to detect the target. Thus, …

Social Cognitive Predictors Of Diabetes Outcomes In Latinos And Whites, Diana Brown

Loma Linda University Electronic Theses, Dissertations & Projects

Investigating health care disparities in ethnic minority populations is an increasingly urgent issue as these disparities lead to higher morbidity and mortality in minorities (National Center of Health Statistics, 2000). There is clear evidence that Latino Americans, the fastest growing minority group in the United States, are more likely to be diagnosed with and experience more severe complications from type 2 diabetes than Anglo Americans. This study surveyed 38 White and 33 Latino diabetes patients from outpatient clinics in an academic medical center. Cultural values (individualism and collectivism), mental health (social support, mental health), and self-efficacy (diabetes and exercise) were …

Risk Behavior, Decision Making, And Music Genre In Adolescent Males, Joseph E. Hampton

Theses, Dissertations and Capstones

The effects of music on risk behavior and decision-making are still unknown. Previous studies have linked music with risky behaviors such as drinking. Evidence shows that performance and decision-making on certain tasks can be altered by the presence of music. This study seeks to evaluate decision-making while in this "altered" state of mind. It is hypothesized that decisions made listening to rock music will be more risky than those made in other conditions. Participants were assessed using several questionnaires and the Iowa Gambling Task. Participants were randomly assigned to no music, classical music, or rock music. Results indicate several interesting …

Peer And Maternal Relationship Predictors Of Adolescent Romantic Conflict Resolution, Pallavi Visvanathan

Electronic Theses and Dissertations

The objective of the current study was to examine whether change in adolescent conflict resolution in romantic relationships is predicted by adolescents' prior interactions with mothers and friends. A community sample of 191 adolescents (96 female), representative of the U.S. population, their mothers and close friends participated in this study. Data collection began when adolescents were in 10th grade (¬Average age = 15.9, SD = .52) and continued for the next five and a half years. Results indicated that teens engaged in positive problem solving, withdrawal, and compliance far more frequently than in aggressive conflict resolution strategies. Hierarchical linear modeling …

The Provision Of Social Support By Adolescent Youth And Their Subsequent Risk For Secondary Traumatic Stress Reactions, Lindsay E. Smart

Electronic Theses and Dissertations

During adolescence, peers become increasingly important sources of social support for youth. In addition to discussing the trials and tribulations of daily life, it is possible that youth are having intimate conversations concerning their experiences of trauma. This study examined the types of traumatic experiences disclosed to youth by their friends, youth's experiences of supporting a friend following disclosure of trauma, youth's secondary traumatic stress (STS) reactions to their friends' disclosures, and potential risk factors for the development of STS. The validity of an adult measure of STS, the Secondary Trauma Scale, with an adolescent population was also explored. Utilizing …

Tolerance Of Sexual Harassment: A Laboratory Paradigm, D. J. Angelone, Damon Mitchell, Kara Carola

Title IX Research and Resources

The present study attempted to develop a laboratory analogue for the study of tolerance for sexual harassment by using an online speed-dating paradigm. In that context, the relation between participants’ sexual harassment attitudes, perpetrator attractiveness, perpetrator status, and perceived dating potential of the perpetrator were examined as factors influencing participants’ tolerance of sexually harassing behavior. Participants were 128 female college students from a small northeastern public university. Results indicated that attractiveness, high social status, and attitudinal beliefs about sexual harassment were all predictive of tolerance for sexual harassment, providing preliminary support for the validity of this paradigm. In addition, participants’ …

The Relationship Between Femininity Ideology And Overt And Relational Aggression And Peer Victimization Among Girls, Anne Powell

Electronic Theses and Dissertations

This study examined the relationship between gender socialization, assessed by the gender ideologies of inauthenticity in relationships and body objectification (Tolman & Porche, 2000), and overt and relational aggression and peer victimization among 212 girls in five Denver, Colorado public middle schools. A feminist developmental perspective was used to 1) examine whether internalized norms of femininity were related to overt and relational aggression and peer victimization; 2) evaluate whether girls used certain types of aggressive behavior to adhere to, or reject, norms of femininity; and 3) assess whether girls who were victimized were more likely than other girls to internalize …

Expectations About Memory Change Across The Life Span Are Impacted By Aging Stereotypes., Tara T. Lineweaver, Andrea K. Berger, Christopher Hertzog

Scholarship and Professional Work - LAS

This study examined whether expectations about memory change with age vary for different personality types. Four adjectives from each of Hummert’s age-stereotype trait sets were selected to create 11 adjective clusters varying in both valence (positive versus negative) and relevance to memory functioning. Three hundred and seventy three participants in three age groups rated the memory abilities of target adults, defined by the adjective clusters, across the adult life span. Consistent with past studies, participants believed in age-related memory decline. However, participants rated target adults with positive personality traits as having better memory ability and less age-related memory decline than …

Connected Coordination: Network Structure And Group Coordination, Mathew D. Mccubbins, Ramamohan Paturi, Nicholas Weller

Faculty Scholarship

Networks can affect a group’s ability to solve a coordination problem. We utilize laboratory experiments to study the conditions under which groups of subjects can solve coordination games. We investigate a variety of different network structures, and we also investigate coordination games with symmetric and asymmetric payoffs. Our results show that network connections facilitate coordination in both symmetric and asymmetric games. Most significantly, we find that increases in the number of network connections encourage coordination even when payoffs are highly asymmetric. These results shed light on the conditions that may facilitate coordination in real-world networks.

How Do People React To Someone Who Has Recently Tested For Hiv? An Experimental Study Of The Effects Of Sexual Orientation And Hiv Status, Stacie A. Wilson

Psychology Theses & Dissertations

HIV/AIDS-related stigma remains prevalent in our society despite advances in medical treatment, and appears to be based on fear of the illness and negative attitudes toward gay individuals. Previous literature examining the phenomenon, enactment, and consequences of HIV/AIDS-related stigma has primarily been based on self-report measures examining participants' imagined reactions toward a person with HIV/AIDS (PWHA). The present study attempted to expand on the self-report findings and contribute uniquely to the literature by examining participants' attitudes toward an individual believed to be gay and HIV-positive after a real-life interaction. This study, which involved the use of a confederate whose sexual …

Effects Of Ancient And Modern, Avoidant And Approach Stimuli On Visual Search Task Reaction Times, Sanja Bojic

Theses : Honours

The threat superiority effect refers to faster and more accurate detection of fearful stimuli. This has been explained as evidence for evolution, as ancient fearful stimuli are detected more quickly than modern fearful stimuli. The aim of this study was to investigate which of two alternate evolutionary explanations best explains the findings. Whereas Ohman and Mineka (2001) dealt only with avoidant responses, Lang suggested that stimuli may evoke either an avoidant (fearful) or approach response, associated with negative or positive valence, respectively. The experiment employed a same-different task where Age (ancient, modern), and Valence (approach, avoidant, neutral) were manipulated and …

Knowing When To Trust Others: An Erp Study Of Decision-Making After Receiving Information From Unknown People, Cheryl Boudreau, Mathew D. Mccubbins, Seana Coulson

Faculty Scholarship

To address the neurocognitive mechanisms that underlie choices made after receiving information from an anonymous individual, reaction times (Experiment 1) and event-related brain potentials (Experiment 2) were recorded as participants played 3 variants of the Coin Toss game. In this game, participants guess the outcomes of unseen coin tosses after a person in another room (dubbed “the reporter”) observes the coin toss outcomes and then sends reports (which may or may not be truthful) to participants about whether the coins landed on heads or tails. Participants knew that the reporter's interests either were aligned with their own (Common Interests), opposed …

Volunteer Functions, Satisfaction, Commitment, And Intention To Leave Government Volunteering, Gisela R. Salas

Graduate Student Dissertations, Theses, Capstones, and Portfolios

Traditionally, volunteerism has been deeply embedded in United States history with citizens showing a high level of social participation. In the United States there are 60.8 million volunteers, however, the supply of volunteer labor has been insufficient to meet the demands of organizations with recent reports showing a decrease. Trends as far back as the 1980s indicated that budgetary constraints coupled with increasing demands makes volunteering the logical alternative to sustain service delivery.

Many community, civic, and governmental organizations need and use volunteers to accomplish their missions. One of the greatest challenges, however, is ensuring that the volunteers remain satisfied …

An Expanded Conceptualization And A New Measure Of Compulsive Buying, Nancy Ridgway, Monika Kukar-Kinney, Kent B. Monroe

Marketing Faculty Publications

Drawing on the theoretical foundation of obsessive‐compulsive spectrum disorder, this article develops an expanded conceptualization and new measure of consumers’ proclivity to buy compulsively. Compulsive buying is defined as a consumer’s tendency to be preoccupied with buying that is revealed through repetitive buying and a lack of impulse control over buying. This measure includes dimensions of both obsessive‐compulsive and impulse‐control disorders. By measuring income‐dependent items or consequences of compulsive buying separately from the compulsive‐buying scale, we develop a measure that has a strong theoretical foundation, well‐documented psychometric properties, and an ability to be applied to general consumer populations.

Measuring Self-Disclosure Over The Internet, David Pope

Psychology Theses & Dissertations

A two-axial measure of disclosure intimacy by Morton (1976, 1978) was expanded to create a new measure usable for linear analyses. Morton's item of "Description" was divided into three "Context" items: Self-Concept, Interpersonal, and Taboo. The other axis of "Evaluation" was divided into four "Expression" items: Detail, Protected, Intensity, and Negativity/Vulnerability. As test data for the measure, demographic information from l50 users' weblogs was compared to free-response disclosures measured with the Morton measure and the linear Context/Expression measure. A multiple regression analysis of profile information versus disclosure intimacy did not reach significance. Results were inconclusive because the measures used in …

Study Of Executive Functioning Training In Adolescents Diagnosed With Autism, Jessica Postil

Loma Linda University Electronic Theses, Dissertations & Projects

This study investigated the effectiveness of a manualized executive functioning training program used with adolescents diagnosed with autism. Three male adolescents were trained on executive function activities using a combination of Applied Behavioral Analysis and executive functioning activities. Training programs were administered individually, lasting for 2 hours per day for 20 days. Participants were tested 1 month before training, 1 week before treatment, immediately after training and at a one-month follow-up. Significant improvements were seen in performance on executive functioning tasks that required motor speed, verbal fluency, monitoring, predicting, planning and organization skills. Significant changes in the participant’s adaptive behavior …

Self-Esteem In Relation To Casual Sex Behavior, Attitudes, And Affect., Kathryn Bieda

Electronic Theses and Dissertations

Casual sex is common on college campuses and is potentially relevant to a person's self-esteem. Unfortunately, data are mixed regarding how self-esteem is influenced by casual sex. This thesis is an attempt to understand how casual sex influences women's self-esteem through a series of questionnaires. Three hypotheses were of interest. The first predicted that sociosexuality and desire would explain casual sex engagement. Second, that casual sex behaviors and attitudes would predict self-esteem. Third, looking only at those who engaged in casual sex; casual sex attitudes and affect would predict self-esteem. Using hierarchical regression, results indicated that there was a curvilinear …

The Use Of Personality Assessments In Designing Environmental Enrichment For Garnett's Bushbabies (Otolemur Garnettii), Lauren Elizabeth Highfill

Dissertations

Recently the study of animal personality has become an important and credible topic of research and a number of studies have revealed personality traits in a variety of species. The consideration of individual animal personality traits is important for animal management and welfare. For example, ensuring inter-individual compatibility in group housing animals may serve to ensure the safety of the whole group. To date, no formal research has been conducted on whether the assessment of individual personality traits could be used as a tool for individualizing environmental enrichment interventions. The goal of environmental enrichment is to increase the rate of …

Evaluation Of A Progressive Model For Identifying Preferred Stimuli For Children With Developmental Disabilities, Amanda M. Karsten

Dissertations

Preference assessments for individuals with disabilities differ along many dimensions, including time requirements for implementation and probability of identifying a hierarchy of relative preferences. Some methods of assessment are also more conducive to use with individuals who exhibit problem behavior or certain prerequisite skills. Inaccurate results and loss of valuable treatment time are among the risks associated with selecting ineffective or unnecessarily lengthy procedures. The purpose of the current investigation was to evaluate a progressive model for conducting preference assessments which incorporates many of the aforementioned considerations. Concurrent-operant reinforcer evaluations were used to verify assessment findings. Based on 17 participants …

Self-Solicited Feedback: Effects Of Hourly Pay And Individual Monetary Incentive Pay, Julie M. Slowiak

Dissertations

The frequency of feedback solicitation under hourly pay and individual monetary incentive pay conditions was examined. A two-group between-subjects design was used with 30 college students in each group. Participants attended three experimental sessions and entered the cash value of simulated bank checks presented on a computer screen. Results indicated that (a) participants who were paid individual monetary incentives did not self-solicit feedback more often than those who were paid an hourly wage, (b) feedback solicitation was not related to individual differences in levels of competition with one's self or competition with others, (c) task performance was higher for individuals …

The Psychophysiology Of Information Processing Differences In Eating Disorders, Kathryn Grace Truitt

Loma Linda University Electronic Theses, Dissertations & Projects

Maladaptive or dysfunctional cognitive factors are believed to be significant contributors to pathology in eating disorders. The emotional Stroop task was used to examine [the] these dysfunctional cognitive factors. A sample of 31 women (14 nonclinical controls, 13 BN, 4 AN) participated in this investigation, after exclusion for ocular and movement artifacts and equipment problems the remaining sample contained 4 women diagnosed with BN, 4 women diagnosed with AN, and 9 matched non-clinical control subjects. Participants completed an Emotional Stroop task comprised of 8 blocks of words. On each trial, a word was presented in one of four colors (black, …

Disruptive Effects Of Aβ Oligomers To The Radial-Arm Maze Performance Of Rats, Kineta Lynn Morgan-Paisley

Dissertations

Converging lines of research have implicated a causal relationship between oligomers of amyloid-β and the cognitive impairments associated with Alzheimer's disease (AD); however, very few studies have provided direct experimental evidence of this relationship and none of those studies have used an established model of working memory. The present study used an established model of working memory, the radial-arm maze, to examine the effects of amyloid-β oligomers on the memory of two groups of rats. The experimental group received ICV injections of the culture media (CM) of Chinese Hamster Ovary (CHO) cells transfected with a human mutation of APP containing …

The Influence Of Species And Context On Human-Dolphin Interactions, Deirdre Breen Yeater

Dissertations

Anthropogenic activities pose a threat to marine mammals around the world. Cetaceans that use coastal waters are at particular risk for potential disturbances caused by vessel traffic and human swimmers. Although many cetacean species are found near the coast of Utila, Honduras, little is known about their behavior or the effects of anthropogenic activities on their behavior. Whether the presence of boats and human swimmers led to short-term changes in dolphin behavior was investigated for three commonly sighted species of dolphins; rough-toothed (Steno bredanensis), spinner (Stenalla longirostris), and bottlenose (Turslops truncatus). The dolphins' behavioral activities, with and without other boats …

Characteristics Of Head Mounted Displays And Their Effects On Simulator Sickness, Jason Moss

All Dissertations

Characteristics of head-mounted displays (HMDs) and their effects on simulator sickness (SS) and presence were investigated. Update delay and wide field of views (FOV) have often been thought to elicit SS. With the exception of Draper et al. (2001), previous research that has examined FOV has failed to consider image scale factor, or the ratio between physical FOV of the HMD display and the geometric field of view (GFOV) of the virtual environment (VE). The current study investigated update delay, image scale factor, and peripheral vision on SS and presence when viewing a real-world scene. Participants donned an HMD and …

Affective Flexibility: Evaluative Processing Goals Shape Amygdala Activity, William A. Cunningham, Jay J. Van Bavel, Ingrid Johnsen Haas

Department of Political Science: Faculty Publications

Although early research implicated the amygdala in automatic processing of negative information, more recent research suggests that it plays a more general role in processing the motivational relevance of various stimuli, suggesting that the relation between valence and amygdala activation may depend on contextual goals. This study provides experimental evidence that the relation between valence and amygdala activity is dynamically modulated by evaluative goals. During functional magnetic resonance imaging, participants evaluated the positive, negative, or overall (positive plus negative) aspects of famous people. When participants were providing overall evaluations, both positive and negative names were associated with amygdala activation. When …

Ethics In Experimentation, Donelson R. Forsyth

Jepson School of Leadership Studies articles, book chapters and other publications

Experimentation in the social sciences, by its very nature, requires researchers to manipulate and control key aspects of the social setting so as to determine what effect, if any, these manipulations have on the people in that setting. Such studies, although unmatched in terms of their scientific yield, nonetheless raise questions of ethics: Do researchers have the moral right to conduct experiments on their fellow human beings? What practices are unacceptable and what procedures are allowable? Can standards be established to safeguard the rights of participants?
