Separating Component Signals Of Episodic Simulation Using A Catch Trial Design, Adrian W. Gilmore Dec 2012

Separating Component Signals Of Episodic Simulation Using A Catch Trial Design, Adrian W. Gilmore

All Theses and Dissertations (ETDs)

Tasks that require mentally simulating events, such as remembering events from one’s past and imagining events from one’s future, have been shown to involve a highly overlapping set of brain regions. Across a growing number of studies, relatively few regions have been found that show differences in activity between remembered and imagined events. However, studies have not disambiguated neural activity related to task orientation: i.e., preparing to remember events from the past or imagine events in the future) from activity related simulating events, per se. The current experiment uses functional MRI and employs a catch trial design to test the …


The Role Of Loneliness And Life Events: Comparing Avoidant And Borderline Personality Features And Their Relation To Depression, Janine Galione Dec 2012

The Role Of Loneliness And Life Events: Comparing Avoidant And Borderline Personality Features And Their Relation To Depression, Janine Galione

All Theses and Dissertations (ETDs)

Personality disorders are theoretically and empirically linked to experiencing high negative affect, such as depression, and individuals with features from some personality disorders, such as borderline: BDL) and avoidant: AVD), are hyper-responsive to rejection. Loneliness has also been established as a vulnerability to the onset of depressive episodes and as an outcome to rejection sensitivity, however the relationship between personality pathology and loneliness is still unclear. The purpose of this study is to compare whether AVD and BDL features might be differentially associated with depression scores by analyzing the interaction with life events and loneliness. We studied a representative, community-based …


Brain Structure In Older Adult Siblings, Nathaniel Lucena Dec 2012

Brain Structure In Older Adult Siblings, Nathaniel Lucena

All Theses and Dissertations (ETDs)

Considerable variability exists in patterns of brain aging within and across individuals. Quantifying familial contributions to brain structure in late life may help us understand this variability. We estimated heritability of gray and white matter volumes and cortical thickness in a sample of older adult full siblings: 2-4 individuals per pedigree; N = 75). Estimation of heritability was based on computation of intraclass correlations. Heritability estimates were higher for total cortical thickness compared to volumes. There was no evidence of overall laterality in heritability estimates, or differences between primary sensory and association regions. There was a tendency for lower estimates …


Effects Of Ownership Intuitions On Allocations In The Dictator Game, John Christner Dec 2012

Effects Of Ownership Intuitions On Allocations In The Dictator Game, John Christner

All Theses and Dissertations (ETDs)

People’s implicit assumptions about ownership might influence their decisions in Dictator Games: DG), leading to generosity. Two studies tested subjects’ intuitions concerning ownership in fictional situations structurally analogous to the DG. Subjects read a story about a ritual in which an old man: experimenter in DG) provided an endowment that Person 1: dictator in DG) had to allocate between self and Person 2: receiver in DG). Subjects were told that in some instances the ritual was interrupted before completion. As an assay of their intuitions regarding ownership, subjects were asked who owned the endowment and how it should be allocated …

Effects Of An Individual Development Account Program On Retirement Saving: Follow-Up Evidence From A Randomized Experiment, Michal Grinstein-Weiss, Michael Sherraden, William Gale, William M. Rohe, Mark Schreiner, Clinton Key Nov 2012

Effects Of An Individual Development Account Program On Retirement Saving: Follow-Up Evidence From A Randomized Experiment, Michal Grinstein-Weiss, Michael Sherraden, William Gale, William M. Rohe, Mark Schreiner, Clinton Key

Center for Social Development Research

Using data from a randomized experiment that ran from 1998 to 2003 in Tulsa, Oklahoma, we examine the 10-year follow-up effects on retirement saving of an Individual Development Account (IDA) program. The IDA program included financial education, encouragement to save, and matching funds for several qualified uses of the savings, including contributions to retirement accounts. The results indicate that, as of 2009, 6 years after the program ended, the IDA program had no impact on the propensity to hold a retirement account, the account balance, or the sufficiency of retirement balances to meet retirement expenses.

Learning To Vote: Informing Political Participation Among College Students, Suzanne Pritzker, Melanie J. Springer, Amanda Moore Mcbride Oct 2012

Learning To Vote: Informing Political Participation Among College Students, Suzanne Pritzker, Melanie J. Springer, Amanda Moore Mcbride

Center for Social Development Research

To inform universities’ capacity to encourage student political participation, we examine associations between four civic influences—civic instruction, deliberative course-based discussion, community service, and service learning—and youth participation during the 2008 presidential election. These four influences were selected because they are commonly integrated into higher education environments. Using an original survey, we employ a broad definition of political behavior to explore ways college students express themselves politically and to examine potential influences on their participation. We hypothesize that students exposed to civic influences are more likely to vote and engage in other participatory activities than those who lack such exposure. Findings …


Racial And Ethnic Disparities In Food Insufficiency: Evidence From A Statewide Probability Sample Of White, African American, American Indian, And Hispanic Infants, Yunju Nam, Jin Huang, Colleen Heflin, Michael Sherraden Oct 2012

Racial And Ethnic Disparities In Food Insufficiency: Evidence From A Statewide Probability Sample Of White, African American, American Indian, And Hispanic Infants, Yunju Nam, Jin Huang, Colleen Heflin, Michael Sherraden

Center for Social Development Research

This study examines racial and ethnic disparities in the experience of food insufficiency among families with infants, focusing on the roles of socioeconomic characteristics. It uses the SEED for Oklahoma Kids baseline survey data collected from a probability sample of white, African American, American Indian, and Hispanic caregivers of infants randomly selected from Oklahoma’s birth certificates. Fairlie’s extension of the Blinder-Oaxaca decomposition is employed to analyze these data. Results suggest that whites experience food insufficiency at a statistically significantly lower rate than do the three minority groups. Compositional gaps in economic and noneconomic resources are found to explain much of …

Discounting Of Hypothetical Monetary Outcomes That Are Both Delayed And Probabilistic, Ariana Mae Vanderveldt Aug 2012

Discounting Of Hypothetical Monetary Outcomes That Are Both Delayed And Probabilistic, Ariana Mae Vanderveldt

All Theses and Dissertations (ETDs)

The value of an outcome is affected both by the delay until its receipt: delay discounting) and by the likelihood of its receipt: probability discounting). Despite being well described by the same hyperboloid function, delay and probability discounting involve fundamentally different processes, as represented by the opposite effect amount has on the degree to which delayed and probabilistic rewards are discounted. Most of the previous research has studied the discounting of delayed and of probabilistic rewards separately, with little research examining more complex situations in which the rewards are both delayed and probabilistic. In the present experiment, participants made choices …


Sensory And Cognitive Declines In Older Adults: A Longitudinal Study, Melanie Storm Bauer Aug 2012

Sensory And Cognitive Declines In Older Adults: A Longitudinal Study, Melanie Storm Bauer

All Theses and Dissertations (ETDs)

In a recent cross-sectional study, as has been found in numerous previous studies, Sommers et al.: 2011) found that age-related declines in hearing, as assessed by pure-tone thresholds, begin around age 20 and continue across the lifespan. In another article published from the same cross-sectional dataset, Hale et al.: 2011) found that working memory ability also begins declining around age 20 and continues throughout life. The present study is a longitudinal follow-up of these two studies in which a sub-sample of older adults: ≥65 years old at the time of original testing approximately four years ago) were re-tested on sensory …


Exploring An Interactive Measure For Preferences In Early Childhood, Narges Afshordi Aug 2012

Exploring An Interactive Measure For Preferences In Early Childhood, Narges Afshordi

All Theses and Dissertations (ETDs)

Three experiments: total N=53) examined whether toddlers show preferences for people and objects in an interactive, touch-screen paradigm. In all experiments, children watched videos of stimuli pairs displayed on two monitors in each trial, and were then given the chance to watch another video of one of the stimuli items by touching the screen on which it had appeared. Experiments 1 and 2 exposed children to interesting vs. boring objects, and engaging vs. boring speakers. Experiment 3 examined children’s responses when presented with one actor who spoke English: native language speaker) compared to another actor who spoke in a foreign …


Knowing More Than We Can Tell: People Are Aware Of Their Biased Self-Perceptions, Kathryn Leigh Bollich Aug 2012

Knowing More Than We Can Tell: People Are Aware Of Their Biased Self-Perceptions, Kathryn Leigh Bollich

All Theses and Dissertations (ETDs)

There is no question that biases exist in people’s self-perceptions of their personality. However, it is not known whether people are aware of these self-biases. In two studies: N = 130), I examined whether people have insight into their positive and negative self-biases across a range of traits. I predicted that self-biases result from self-deception: i.e., the intentional distortion of more realistic self-views), and as such, people should have some awareness of their self-biases. As predicted, people with positive biases: i.e., self-perceptions that are more positive than a reputation-based criterion measure) described themselves as positively biased, and people with overly …

Household Assets, School Enrollment And Parental Aspirations For Children's Education In Rural China: Does Gender Matter?, Suo Deng, Jin Huang, Minchao Jin, Michael Sherraden Jul 2012

Household Assets, School Enrollment And Parental Aspirations For Children's Education In Rural China: Does Gender Matter?, Suo Deng, Jin Huang, Minchao Jin, Michael Sherraden

Center for Social Development Research

Using rural household data from the China Household Income Project (CHIP) 2002, this paper provides an analysis of different effects of household assets independent of family income on children’s school enrollment and parental aspirations for education, examining both outcomes by child’s gender. The study first compares the responsiveness of boys’ and girls’ enrollment to the improvement of household assets, measured as liquid assets and net worth, relative to family income. The multivariate regression analysis further detects the effects of household assets on both boys’ and girls’ school enrollment and parental aspirations for children’s future education by child’s gender. Statistical results …


Validity Of Infact Race/Ethnicity From Birth Certificates In The Context Of U.S. Demographic Change, Lisa Reyes Mason, Yunju Nam, Youngmi Kim Jul 2012

Validity Of Infact Race/Ethnicity From Birth Certificates In The Context Of U.S. Demographic Change, Lisa Reyes Mason, Yunju Nam, Youngmi Kim

Center for Social Development Research

In this study, we examined consistency of infant race/ethnicity across two data sources (N=2,63) using measures of sensitivity and positive predictive value. First we created and compared conventional measures of infant race/ethnicity from 2007 Oklahoma birth certificates and SEED for Oklahoma Kids baseline survey data, classifying infants as White, African American, American Indian, Asian, or Hispanic. Then we created and tested alternative measures with a biracial classification, based on biological parentage from birth certificates or parent report of infant biracial identity in the survey. We find that, for conventional measures, sensitivity is highest for Whites and African Americans and lowest …

Are Child Development Accounts Inclusive? Early Evidence From A Statewide Experiment, Sondra G. Beverly, Youngmi Kim, Michael Sherraden, Yunju Nam, Margaret Clancy

Center for Social Development Research

A key objective of Child Development Accounts (CDAs) is to increase college completion rates among disadvantaged youth by helping families accumulate assets for college and by encouraging youth to see themselves as college bound. While the major asset-building programs in the United States largely benefit socioeconomically advantaged individuals, CDAs explicitly aim to facilitate account holding and asset accumulation by disadvantaged families. But do CDAs meet the goal of being inclusive? This research uses data from a large CDA experiment with probability sampling and random assignment to examine early CDA savings outcomes. Findings indicate that the CDA improves outcomes for several …


Volunteerism For Peace In East Africa, Benjamin Lough, Jacob Mwathi Mati Jun 2012

Volunteerism For Peace In East Africa, Benjamin Lough, Jacob Mwathi Mati

Center for Social Development Research

Volunteering is central to any community-centered development intervention. As such, volunteers can contribute substantially to establishing and preserving peace. This paper describes various interpersonal, intergroup, and institutional theoretical perspectives to explain why volunteerism is particularly suited to peacemaking and peacekeeping. Special consideration is given to how involving young volunteers may be highly beneficial to peacemaking and peacekeeping. The paper emphasizes the “added value” of utilizing volunteers in peace and development organizations, and provides specific examples from the Eastern African region that illustrate how volunteerism is being used to prevent conflict, to mediate and transform active conflict, and to reduce the …


Civic Service And Asset Building In Generating Livelihoods Among Youth In Africa, Benjamin J. Lough, Margaret S. Sherraden Jun 2012

Civic Service And Asset Building In Generating Livelihoods Among Youth In Africa, Benjamin J. Lough, Margaret S. Sherraden

Center for Social Development Research

Given high rates of unemployment among African youth, civic service offers a promising strategy for preparing young people for the labor market. Despite its potential, a lack of service opportunities, incentives, and competing livelihood needs, frequently prevent young people from volunteering. This paper reviews the debate on financial remuneration for volunteering, and describes innovative “hybrid” ways to incentivize and support young volunteers. These approaches offer the potential to build financial assets during service in the form of savings, stipends, and microenterprise credit or education awards. This paper highlights programs in several regions of Africa where similar approaches have been piloted. …


Patient Perceptions Of Comorbid Depression In Heart Disease, Rebecca Lynn Reese Akcakaya Jun 2012

Patient Perceptions Of Comorbid Depression In Heart Disease, Rebecca Lynn Reese Akcakaya

All Theses and Dissertations (ETDs)

Depression is a risk factor for the development of heart disease, as well as for poor prognosis among patients with existing disease. However, clinical trials of treatment of depression in patients with heart disease have not resulted in improved cardiac outcomes, and have demonstrated modest effects on depression. The nature of depression in heart patients must be better understood in order to improve treatment and health outcomes. In samples of patients with medical illness as well as in patients with depression, illness perceptions have been useful in predicting both treatment outcomes and self-management behaviors such as coping and adherence. This …


Informing Policy On Volunteer Service Through Agency-Based Evaluations, Nancy Morrow-Howell, Susan Stapleton, Amanda Moore Mcbride Jun 2012

Informing Policy On Volunteer Service Through Agency-Based Evaluations, Nancy Morrow-Howell, Susan Stapleton, Amanda Moore Mcbride

Center for Social Development Research

This working paper describes the evidence-based policy making process. We focus on what information is needed to inform policy development and decision-making on volunteer service and then how this information can be most effectively disseminated to policy makers, outlining a range of specific strategies. Existing volunteer service research is used as illustration. Implications are drawn for the capacity of agency staff to implement the research methods and strategies that are discussed.
