A Randomized Trial To Evaluate The Course Of Effects Of A Program To Prevent Adolescent Depressive Symptoms Over 12 Months., Patrick Pössel, Jill L. Adelson, Martin Hautzinger Dec 2011

A Randomized Trial To Evaluate The Course Of Effects Of A Program To Prevent Adolescent Depressive Symptoms Over 12 Months., Patrick Pössel, Jill L. Adelson, Martin Hautzinger

Faculty and Staff Scholarship

Although few prevention studies have been designed to investigate the course of prevention effects over time, it seems that the effects on depressive symptoms increase from post-intervention to 6-month follow-up but then decrease with longer lags to follow-up. Furthermore, previous prevention studies have found differential intervention effects for boys and girls without testing possible explanations for this effect. The present randomized control group study with 301 8th-grade students examined the effects of a depression prevention program from baseline until 12-month follow-up. As expected, while positive intervention effects were found on girls’ depressive symptoms, no such effects were found on boys’ …

Relationship Maintenance And Facebook, Kelli Kapp Dec 2011

Relationship Maintenance And Facebook, Kelli Kapp

Communication & Leadership Dissertations and Theses

Research to date on Facebook users has not included part of Generation Y, those born from 1976 through 1989. This study examined the use of Facebook to maintain relationships to extend previous work by Steinfield and Lampe (2009), Pennington (2009), and Bryant and Marmo (2009) whose work served as a lens for comparison. A survey questionnaire (N=215) was administered to Facebook users to determine their uses for the site, frequency of use, and perceived closeness of Facebook friends. Results suggested Facebook has become a daily part of respondent’s lives. Questions regarding Facebook use indicated the number one motivator for using …

What Is The Perceived Impact Of Social Media On Personal Relationships In Adolescence?, Samantha Sexton Dec 2011

What Is The Perceived Impact Of Social Media On Personal Relationships In Adolescence?, Samantha Sexton

Communication & Leadership Dissertations and Theses

A study was conducted to review the perceived impact social media plays in children’s personal relationships during adolescence. Surveys and interviews were sent out to 50 subjects in an effort to gather and compile information for analysis. The Compulsive Internet Use Scale (Meerkerk et al.) was used in a survey format and administered to participants to access their perceptions in which their child(ren) and/or grandchild(ren)’s use the internet and social media. A 5-point Likert Scale was also implemented in order to provide measurable analysis. Adult anxiety in regards to social media was observed at different levels depending on the developmental …

Identifying Online Communities As Self-Sustaining Ecosystems For Fulfilling Members' Needs, Elliot S. Volkman Dec 2011

Identifying Online Communities As Self-Sustaining Ecosystems For Fulfilling Members' Needs, Elliot S. Volkman

Communication & Leadership Dissertations and Theses

The following study shows what current online community members expect of their communities, and how each member plays a vital role in the self-sustaining ecosystem. In the past online communities were self-contained and managed by moderators who would often generate much of the content, and set guidelines for the users within the community. Based on the results of this study members now show that there are two different types of Lurkers (Active and Passive), which make up the majority of all members within a community. Active Lurkers have been identified as those who share content externally and back to their …

Change Detection Memory In Rhesus Monkeys And Humans, Lauren C. Elmore Dec 2011

Change Detection Memory In Rhesus Monkeys And Humans, Lauren C. Elmore

Dissertations and Theses (Open Access)

Visual short-term memory (VSTM) is the storage of visual information over a brief time period (usually a few seconds or less). Over the past decade, the most popular task for studying VSTM in humans has been the change detection task. In this task, subjects must remember several visual items per trial in order to identify a change following a brief delay interval. Results from change detection tasks have shown that VSTM is limited; humans are only able to accurately hold a few visual items in mind over a brief delay. However, there has been much debate in regard to the …

The Accuracy Of Drivers' Perceptions Of The Effects Of Headlight Glare On Their Ability To Recognize Pedestrians At Night, Stephanie Whetsel Dec 2011

The Accuracy Of Drivers' Perceptions Of The Effects Of Headlight Glare On Their Ability To Recognize Pedestrians At Night, Stephanie Whetsel

All Theses

Recently, researchers have begun to assess the extent to which drivers believe their ability to see is degraded by headlight glare. Research has suggested that drivers may overestimate the extent to which glare from headlamps degrades their ability to see letters. This project extended this research by quantifying the accuracy with which drivers judge that glare interferes with their ability to see pedestrians at night. On average, participants overestimated the distance at which drivers would see a pedestrian by a factor of more than three. Headlight glare disrupted participants' ability to recognize the pedestrian wearing both non-retroreflective and reflective clothing …

An Extension Of Social Facilitation Theory To The Decision-Making Domain, Allison Wallace Dec 2011

An Extension Of Social Facilitation Theory To The Decision-Making Domain, Allison Wallace

All Theses

Social facilitation has traditionally been defined as the influence of the presence of others on an individual's task performance. Social presence has been shown to either facilitate or impair performance based on various moderating variables, including the more recent investigation of individual differences, but researchers have yet to extend social facilitation theory to the domain of decision-making. This study evaluates the effect of social presence on individual decision-making, using the personality traits of extraversion, neuroticism, self-esteem, social anxiety, and trait anxiety as potential moderating variables of this effect. We found that affiliative individuals, marked by high extraversion and high self-esteem, …

The Relationship Between Physical Activity And Cognitive Symptoms Of Depression, Katy Manganella Dec 2011

The Relationship Between Physical Activity And Cognitive Symptoms Of Depression, Katy Manganella

Psychology and Counseling Theses

Existing research on exercise habits typically focuses on the physical health benefits. However, this research tends to neglect the potential psychological benefits of exercise. The present research adopts a different perspective by investigating the relationship between exercise and different symptom types of depression. By establishing the amount of physical activity participants consider to constitute exercising on a regular basis, participants were separated into self-reported high and low-exercise groups and completed the Zung-Self Rating Depression Scale. By employing a factor analysis of the Zung SDS, the results were analyzed assessing each symptom type of depression: Cognitive, affective, and somatic. Results suggest …

Disclosing An Invisible Disability During The Interview Process: A Qualitative Study, John Elias Sassin Dec 2011

Disclosing An Invisible Disability During The Interview Process: A Qualitative Study, John Elias Sassin

Graduate Theses and Dissertations

Rehabilitation professionals, persons with disabilities and employers were asked to participate in a focus group interview exploring the phenomena of disclosing invisible disabilities during the interview process. This Qualitative study examined disclosure of disability from each stakeholder's perspective in an effort to understand its impact on the interview. After transcribing the focus group interview and analyzing the data; five themes emerged reflecting each stakeholder's views on disclosure. The themes revealed the persistence of attitudinal barriers that people with disabilities face in seeking employment; if and when a person should disclose; what are the positive and negative aspects of disclosure and …

Perceptions Of Sexual Dangerousness: Accurate Identification Of Sexual Offenders From Static Photographs, Amber Jean Culbertson-Faegre Dec 2011

Perceptions Of Sexual Dangerousness: Accurate Identification Of Sexual Offenders From Static Photographs, Amber Jean Culbertson-Faegre

Graduate Theses and Dissertations

The present research expands understanding of the phenomenon of accurate identification of sexually dangerous men. Study 1 was designed to examine the influence of experience on accuracy of perceptions of sexual dangerousness. Receiving feedback about test trials increased accuracy on future trials at a marginally significant level. Study 2 was designed to determine the importance of specific facial features on these judgments. This study, however, failed to replicate the findings from the first study. Implications for Study 1, as well as possible explanations for Study 2 are discussed.

The Relation Between Children's Perceived Containment And Parental Antisocial Behavior, Joye L. Henrie Dec 2011

The Relation Between Children's Perceived Containment And Parental Antisocial Behavior, Joye L. Henrie

Graduate Theses and Dissertations

Researchers have invoked a variety of theories when discussing the relation between children's orientation to authority and the development of antiSocial behavior (ASB). Here, the focus is children's sense of containment. Previous studies revealed an association between perceived containment and child externalizing behaviors. In this study, the degree to which a child's sense of containment is related to parents' level of ASB was examined. One hundred sixty aggressive children and their parents participated. I hypothesized that ineffective discipline would moderate the relation between parent ASB and child perceived containment. I expected to find an inverse relation between parents' level of …

Effect Of Environmental Conditions On Perceived Psychological Restorativeness Of Coastal Parks, J. Aaron Hipp, Oladele A. Ogunseitan Dec 2011

Effect Of Environmental Conditions On Perceived Psychological Restorativeness Of Coastal Parks, J. Aaron Hipp, Oladele A. Ogunseitan

Brown School Faculty Publications

We investigated the hypothesis that perception of psychological restorativeness during visits to coastal parks is modified by objective and perceived environmental conditions. Visitors (n=1,153) to California beaches completed a survey on perceived weather, environmental quality, and perceived restorativeness. We used generalized ordinal logistic models to estimate the association between environmental parameters and odds of perceiving higher levels of restorativeness. Visitors perceived greater restorativeness at beaches when ambient temperatures were at or below mean monthly temperatures and during low tides. The odds of perceiving the environment as more psychologically restorative were three times greater when visiting on days defined by government …

Trajectories Of Psychological Distress Among Low-Income, Female Survivors Of Hurricane Katrina, Sarah Ryan Lowe Dec 2011

Trajectories Of Psychological Distress Among Low-Income, Female Survivors Of Hurricane Katrina, Sarah Ryan Lowe

Graduate Doctoral Dissertations

The purpose of this study was to investigate trajectories of psychological distress among low-income women, primarily unmarried and African American, who survived Hurricane Katrina (N = 386). Data were collected in the year prior to the hurricane, as well as approximately one and three years thereafter. Using Latent Class Growth Analysis (LCGA), we detected six distinct trajectory groups. Over half of participants fit into a trajectory consistent with resilience; that is, they maintained low levels of psychological distress over the course of the study, but experienced an elevation in symptoms at the first pre-disaster time point, followed by a return …

Expanding A Model Of Female Heterosexual Coercion: Are Sexually Coercive Women Hyperfeminine?, Elizabeth Anne Schatzel-Murphy Dec 2011

Expanding A Model Of Female Heterosexual Coercion: Are Sexually Coercive Women Hyperfeminine?, Elizabeth Anne Schatzel-Murphy

Graduate Doctoral Dissertations

The present study aimed to replicate a preliminary model of female heterosexual coercion and subsequently expand the model with gender- and race-related variables. The preliminary model, which specified sexual compulsivity, sexual dominance, sociosexuality, and prior sexual abuse, as predictors of female heterosexual coercion, was sufficiently replicated with a racially diverse sample of college women. The model was then successfully expanded by adding rape myth acceptance and hyperfemininity to the model. Hyperfemininity was found to be a core predictor of female heterosexual coercion, challenging the notion that sexual coercion is an inherently "masculine" behavior. Actual minority status, perceived minority status, and …

The Social Negotiation Of Ambiguous In-Between Stigmatized Identities: Investigating Identity Processes In Multiracial And Bisexual People, Vali Dagmar Kahn Dec 2011

The Social Negotiation Of Ambiguous In-Between Stigmatized Identities: Investigating Identity Processes In Multiracial And Bisexual People, Vali Dagmar Kahn

Graduate Doctoral Dissertations

To date, most bisexual and multiracial identity models in psychology capture a largely internal developmental process (Collins, 2000; Kich, 1992; Weinberg, Williams & Pryor, 1994). However, individuals learn to manage their socially stigmatized identities in social interactions (Goffman, 1963). While the demands to socially negotiate stigmatized identity affect all minority peoples, individuals with in-between ambiguous stigmatized identities, such as multiracial and bisexual people, must negotiate also being situated at the margins of their own reference groups (e.g. heterosexual and gay/lesbian). Using a comparative grounded theory approach, this study explored the question: How do experiences of socially negotiating an in-between ambiguous …

Examining Experience In Depressed And Nondepressed Individuals, Jedidiah D. Gunter Dec 2011

Examining Experience In Depressed And Nondepressed Individuals, Jedidiah D. Gunter

UNLV Theses, Dissertations, Professional Papers, and Capstones

The inner experience of nine depressed and nine nondepressed individuals was explored using Descriptive Experience Sampling. Each participant completed four days of descriptive experience sampling, exploring about six moments of their inner experience on each sampling day. Although the Depressed participants self-reported substantially higher levels of depressive symptomatology on the Center for Epidemiological Studies Depression scale (CES-D) on each day of sampling, the differences in the frequency of depressive symptomatology in the inner experiences of these two groups were not statistically significant. Despite the group differences not reaching statistical significance, the Depressed group experienced somewhat more frequent moments of depression, …

The Relationship Between The Functions Of School Refusal Behavior And Family Environment, Rachel Marie Schafer Dec 2011

The Relationship Between The Functions Of School Refusal Behavior And Family Environment, Rachel Marie Schafer

UNLV Theses, Dissertations, Professional Papers, and Capstones

The current study examined the relationship between the functions of school refusal behavior and family environment characteristics in a community sample of youth. The primary aim was to determine the family environments most strongly associated with each function of school refusal behavior in an ethnically diverse, community-based sample of youths referred to the legal process for absenteeism. Hypotheses for the current study were based on the premise that family environment characteristics of the community sample of youths with problematic absenteeism would generally resemble those identified in previous clinical samples. The first hypothesis was that youth who refuse school primarily to …

Dealing With The Threats Inherent In Unproctored Internet Testing Of Cognitive Ability: Results From A Large-Scale Operational Test Program, Filip Lievens, Eugene Burke Dec 2011

Dealing With The Threats Inherent In Unproctored Internet Testing Of Cognitive Ability: Results From A Large-Scale Operational Test Program, Filip Lievens, Eugene Burke

Research Collection Lee Kong Chian School Of Business

There is little information available about operational systems of unproctored Internet testing (UIT) of cognitive ability and how they deal with the threats inherent in UIT. This descriptive study provides a much-needed empirical examination of a large-scale operational UIT system of cognitive ability that implemented test design and verification testing for increasing test security and honest responding. Test security evaluations showed item exposure and test overlap rates were acceptable. Aberrant score evaluations revealed that negative score change (higher unproctored scores than proctored ones) was negligible. Implications for UIT research are discussed.

The Good Life In Psychotherapy: Implicit And Influential, Emily Lonas Morris Dec 2011

The Good Life In Psychotherapy: Implicit And Influential, Emily Lonas Morris

Theses and Dissertations

The good life, or a flourishing life, is a vision of how people ought to best live their lives. Though this vision is vital to the conduct of psychotherapy, it is generally overlooked, and thus unexamined. The therapist's vision of the good life for the client guides his or her implicit and explicit interventions. Despite this, there is relatively little discussion about this vital topic, and relatively little training into the various approaches to the good life. In this thesis, I argue that this relative lack of examination and training is due to the lack of perceived options regarding conceptions …

Mexican American Youths’ Academic Outcomes: The Role Of Ethnic And Academic Socialization In Buffering Discrimination, Spencer M. Richards Dec 2011

Mexican American Youths’ Academic Outcomes: The Role Of Ethnic And Academic Socialization In Buffering Discrimination, Spencer M. Richards

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

An increasingly diversifying educational landscape in the United States has accompanied distressing academic disparities among ethnic minority youths. As Latinos represent the largest and fastest growing ethnic minority group within the U.S., particular attention to their academic outcomes is warranted. Alarming educational statistics have been reported for Latinos, with some estimating that nearly half fail to complete high school, and only a fraction go on to complete a degree in higher education. As Latinos grow to represent an increasing segment of the American educational system, more attention is required to understand what leads Latinos to engage (or disengage) in the …

Going Beyond The Multicultural Experience-Creativity Link: The Mediating Role Of Emotions, Chi-Ying Cheng, Angela K. Y. Leung, Tsung-Yu Wu Dec 2011

Going Beyond The Multicultural Experience-Creativity Link: The Mediating Role Of Emotions, Chi-Ying Cheng, Angela K. Y. Leung, Tsung-Yu Wu

Research Collection School of Social Sciences

This research examines the mediating role of emotions implicated in the multicultural experience—creativity link. We propose that when individuals are dealing with apparent cultural contradictions upon encountering two cultures simultaneously, mentally juxtaposing dissonant cultural stimuli could lower positive affect or increase negative affect, which could in turn induce a deeper level of cognitive processing of cultural discrepancies and inspire creativity. Two studies compared dual cultural exposure versus single cultural exposure among bicultural Singaporeans (Study 1) and compared self-relevant (jointly presenting local and foreign cultures) versus self-irrelevant (jointly presenting foreign cultures only) dual cultural exposure among monocultural Taiwanese (Study 2). As …

The Relationship Of Acculturation And Acculturative Stress In Latina/O Youths’ Psychosocial Functioning, Marsha Tafoya Dec 2011

The Relationship Of Acculturation And Acculturative Stress In Latina/O Youths’ Psychosocial Functioning, Marsha Tafoya

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

This study was conducted to better understand how acculturation and acculturative stress are related to self-esteem, depression, substance use, and substance use problems in 206 Latina/o youth. Acculturation is the social and psychological process of change that occurs when an individual or group comes in contact with a different culture. The acculturation process can be positive, improving one’s life chances in the new culture, or it could be negative due to the challenging nature of change and adaptation to new cultural and social expectations. This difficulty creates a type of stress, called acculturative stress that has been found to be …

Evolution, Terror Management Theory, And Humans’ Relationship With Nature, Joshua Warren Vinocour Nov 2011

Evolution, Terror Management Theory, And Humans’ Relationship With Nature, Joshua Warren Vinocour

Dissertations

This study investigated the savannah hypothesis, an evolutionary explanation for human environmental preference. It aimed to address some of the methodological shortcomings of prior research while simultaneously investigating the role of non-evolutionary influences, such as existential anxiety and individual differences. Ninety-eight undergraduate participants were shown photos of Natural, Mixed, and Built settings and rated the visual attractiveness of each photo. Results showed that Built scenes were preferred over Natural and Mixed scenes, in contradiction to the savannah hypothesis. Existential anxiety, however, did not appear to influence photo ratings. Individual differences, such as ethnicity and the quality participants’ previous outdoor experiences …

Comparing The Efficacy Of Two Cognitive Dissonance Interventions For Eating Pathology: Are Online And Face-To-Face Interventions Equally Effective?, Kasey Serdar Nov 2011

Comparing The Efficacy Of Two Cognitive Dissonance Interventions For Eating Pathology: Are Online And Face-To-Face Interventions Equally Effective?, Kasey Serdar

Theses and Dissertations

Clinical and subclinical eating pathology are common, especially among female undergraduates. Such problems are often chronic and associated with a range of negative medical and psychological outcomes. Thus, it is important to develop effective prevention programs to reduce eating disorder risk. Numerous studies suggest that dissonance-based prevention programs are the most successful in reducing eating disorder risk factors, however, such programs might not be convenient for students limited by scheduling restraints or geographic proximity. Further, some students may be reluctant to attend such groups due to lack of anonymity. One way to address these potential barriers is to adapt dissonance-based …
