Diaphragmatic Breathing And Its Effect On Inhibitory Control, Matthew Russell

Theses and Dissertations--Psychology

Evidence suggests that slow paced diaphragmatic breathing (DB) can significantly affect prefrontal cortex functions through increasing an individual’s physiological self-regulatory capacity. The current research demonstrates the effects of paced DB on inhibitory control, which is considered to be a reliable measure of behavioral self-regulation. Eighty healthy participants were randomly assigned to one of two conditions (20 males and females each). Participants were instructed on either DB at a pace of six-breaths per minute (BPM) or instructions on environmental awareness and asked to breathe at 12 BPM. Following training, all participants completed a computer-based task designed to examine inhibitory processes. Physiological …

Acute Effects Of Alcohol On Simulated Driving Performance And Self-Perceptions Of Impairment In Dui Offenders, Nicholas A. Van Dyke

Theses and Dissertations--Psychology

Licensed drivers arrested for driving under the influence (DUI) of alcohol have increased rates of vehicle crashes, moving violations, and traffic tickets (Evans, 2004). To date, no research has examined specific self-regulatory mechanisms of the DUI driver under a dose of alcohol that might underlie risky driving behavior. The present study examined the degree to which DUI drivers display an increased sensitivity to the acute impairing effects of alcohol on driving performance and overestimate their driving fitness following alcohol consumption. Adult drivers with a history of DUI and a demographically-matched group of control drivers without a DUI were tested following …

Trauma, Personality, And Behavior: A Longitudinal Study Predicting Adverse Outcomes After Sexual Assault From Personality Prior To The Assault, Jessica L. Combs

Theses and Dissertations--Psychology

Exposure to sexual assault results in ongoing harms for women. After an assault, some women engage higher levels of externalizing behaviors, such as drinking problems and drug use, and others experience higher levels of internalizing dysfunction, such as clinical anxiety and clinical depression. In a longitudinal sample of 1929 freshman college women assessed across three time points, I found the following. Pre-assault negative urgency (the tendency to act rashly when distressed) interacted with assault exposure to predict increased subsequent drinking and initiation of drug use. Pre-assault trait anxiety/depression interacted with assault exposure to predict increased subsequent clinical anxiety and depression. …

Do We Know Who We Are By Knowing Who We Are Not?: The Effects Of Including Disliked Others In The Self-Concept, Stephanie B. Richman

Theses and Dissertations--Psychology

People include other people in their self-concept. Research has examined the causes and effects of including liked, but not disliked others into the self-concept. Liked others are included because of a motivation to affiliate and get closer to the other person. The current investigation examined whether disliked others are included as a result of a motivation to differentiate and distinguish oneself from the other person. It also examined how self-concept inclusion of disliked others affects self-concept clarity. First, I tested whether people include disliked others into their self-concepts by showing a memory bias for disliked others similar to that of …

Negative Urgency, Pubertal Onset And The Longitudinal Prediction Of Alcohol Consumption During The Transition From Preadolescence To Adolescence, Lauren Helena Boyle

Theses and Dissertations--Psychology

Alcohol use in early adolescence is associated with numerous concurrent and future problems, including diagnosable alcohol use disorders. The trait of negative urgency, the tendency to act rashly when distressed, is an important predictor of alcohol-related dysfunction in youth and adults. The aim of this study was to test a model proposed by Cyders and Smith (2008) specifying a puberty-based developmental increase in negative urgency, which in turn predicts subsequent increases in early adolescent drinking. In a sample of 1,910 youth assessed semi- annually from spring of 5th grade through spring of 8th grade, we found support for this model. …

Facial And Body Emotion Recognition In Infancy, Leah Oberst

Theses and Dissertations--Psychology

Adults are experts at assessing emotions, an ability essential for appropriate social interaction. The present study, investigated this ability’s development, examining infants’ matching of facial and body emotional information.

In Experiment 1, 18 6.5-month-olds were familiarized to angry or happy bodies or faces. Those familiarized to bodies were tested with familiar and novel emotional faces. Those habituated to faces were tested with bodies. The 6.5-month-old infants exhibited a preference for the familiar emotion, matching between faces and bodies.

In Experiment 2, 18 6.5-month-olds were tested with faces and bodies displaying anger and sadness. Infants familiarized to faces showed a familiarity …

Effects Of Coaching In The Detection Of Malingered Attention Deficit/Hyperactivity Disorder In A College Sample, Maryanne Edmundson

Theses and Dissertations--Psychology

College students may feign symptoms of ADHD to gain access to stimulant medications and academic accommodations. Research has shown that it can be difficult to discriminate malingered from genuine symptomatology, especially when evaluations are based only on self-report. The present study investigated whether the average student given no additional information could feign ADHD as successfully as those who were coached on symptoms. Similar to Jasinski, Harp, Berry, Shandera-Ochsner, Mason, & Ranseen (2011) and other research on feigned ADHD, an extensive battery of neuropsychological, symptom validity, and self-report tests was administered. Undergraduates with no history of ADHD or other psychiatric disorders …

Eating Disorder Onset In Young Girls: A Longitudinal Trajectory Analysis, Carolyn M. Pearson

Theses and Dissertations--Psychology

To investigate whether there are different patterns of development for binge eating and purging behavior among pre-adolescent and early adolescent girls, I conducted trajectory analyses of those behaviors in 938 girls across eight waves of data from the spring of 5^th grade (the last year of elementary school) through the spring of 9^th grade (the first year of high school). Analyses revealed four separate developmental trajectories for binge eating behavior (labeled none, increasing, decreasing, and high steady) and three separate developmental trajectories for purging behavior (labeled none, dabble, and increasing). Fifth grade scores on risk factors that were …

The Ffoci, And Other Measures And Models Of Ocpd, Cristina M. Pinsker

Theses and Dissertations--Psychology

The Five Factor Obsessive Compulsive Inventory (FFOCI) was developed in part to facilitate a shift from the categorical classification of personality disorder to a dimensional model; more specifically, the five-factor model. Questions though have been raised as to whether obsessive-compulsive personality disorder can be understood as a maladaptive variant of FFM conscientiousness. The purpose of the present study was to provide a further validation of the FFOCI, as well as to compare and contrast alternative measures and models of OCPD. A total of 380 participants, including 146 oversampled for OCPD traits, were recruited from introductory psychology courses at the University …

Examining The Vulnerability Of Inhibitory Control To The Impairing Effects Of Alcohol, Melissa A. Miller

Theses and Dissertations--Psychology

There is growing evidence that acute changes in fundamental mechanisms of impulse control contribute to the transition from social drinking to abusive drinking. One component of impulsivity concerns the ability to inhibit maladaptive behaviors (i.e., inhibitory control). Inhibitory mechanisms are reliably shown to be sensitive to the impairing effects of alcohol, and studies have begun to show that this impairment fails to recover at the same speed as other aspects of behavior. However, the degree to which inhibitory control develops tolerance to alcohol has only been examined under limited conditions. This dissertation consists of three studies examining contexts in which …

Temperament And Personality Traits As Predictors Of Preschool Odd Symptoms, Longitudinal Course, And Impairment, Brittany L. Zastrow

Theses and Dissertations--Psychology

Oppositional Defiant Disorder (ODD) is commonly conceptualized as a disorder of negative affect and low effortful control. Currently, it is unclear whether temperament and personality traits associated with negative affect and effortful control can be useful assessment tools for identifying ODD early during development. This study examined the relationship between temperament and personality traits and ODD in a clinical sample of preschoolers. Results suggest that, at this age, temperament and personality traits of negative affect and neuroticism and effortful control and conscientiousness/agreeableness are not associated with one another. High negative affect, low conscientiousness, and low agreeableness were all specifically …

The Effects Of Alternate-Line Shading On Visual Search In Grid-Based Graphic Designs, Michael P. Lee

Theses and Dissertations--Psychology

Objective: The goal of this research was to determine whether alternate-line shading (zebra-striping) of grid-based displays affects the strategy (i.e., “visual flow”) and efficiency of serial search. Background: Grids, matrices, and tables are commonly used to organize information. A number of design techniques and psychological principles are relevant to how viewers’ eyes can be guided through such visual works. One common technique for grids, “zebra-striping,” is intended to guide eyes through the design, or “create visual flow” by alternating shaded and unshaded rows or columns. Method: 13 participants completed a visual serial search task. The target was embedded in a …

Be Ye Fruitful And Multiply: Does Religious Activation Increase Reproductive Desire?, Erik M. Lund

Theses and Dissertations--Psychology

While many norms sustain or destabilize certain religions, one domain is particularly relevant to the survival of some religions over others: norms about fertility and reproduction. Thus far, several ethnographic and correlational studies have found a positive association between religiosity and fertility rate, but there is a dearth of laboratory investigation utilizing experimental methods to isolate causation. In Study 1, I found that experimentally activating religious concepts led to an increased desire to have children (N = 462). In Study 2, the focal study, I attempted to replicate and extend the previous study by examining implicit behavior (N …

Korean American Adolescents And Their Mothers: Intergenerational Differences And Their Consequences, Hui Chu

Theses and Dissertations--Psychology

The current study examined the links and mechanisms associated with intergenerational cultural conflict, psychological distress, and the intergenerational differences in acculturation and model minority stereotype (MMS) endorsement for South Korean immigrants. Specifically, Korean American adolescents’ (ages 12-19, M = 15.3, SD = 1.71) and their mothers’ (N = 209 dyads) acculturation difference and MMS endorsement difference were measured and analyzed as predictors of intergenerational cultural conflict and psychological distress for adolescents. Furthermore, the study analyzed intergenerational cultural conflict as a mediator in the acculturation gap-distress and the MMS endorsement-distress paths. Results indicated that when mothers and their adolescents differed …

Juror Bias In Perceptions Of Lesbian Intimate Partner Violence, Nesa Elizabeth Wasarhaley

Theses and Dissertations--Psychology

Homophobic attitudes pervade our society and specifically our justice system, which negatively impact legal protection for lesbian victims of intimate partner violence (IPV). Juror stereotypes about IPV victims and perpetrators as well as their biases based on sexual orientation may be a hindrance to IPV cases being reported and successfully prosecuted. The primary goal of this study was to investigate the impact that mock jurors’ attitudes toward homosexuals and gender roles, and their acceptance of myths about domestic violence had on their perceptions of lesbian IPV. Heterosexual undergraduate students (N = 259) read a trial summary in which the defendant …

Contribution Of Nucleus Accumbens Core To Impulsive Choice: Role Of Dopamine And Glutamate Systems, Justin R. Yates

Theses and Dissertations--Psychology

Impulsive choice refers to the inability to delay gratification and is associated with increased drug abuse vulnerability. Understanding the underlying neural mechanisms linking impulsive choice and drug abuse can contribute to improved treatment options for individuals with substance use disorders. Evidence suggests a major role for nucleus accumbens core (NAcc) in impulsive choice and the reinforcing effects of drugs of abuse. The neurotransmitters glutamate (Glu) and dopamine (DA) are implicated in the neural adaptations observed in drug addiction; however, the role of intra-NAcc Glu and DA in impulsive choice is unclear. Rats were trained in a delay discounting task, in …

Self-Regulation In Older Adults: The Prioritization Of Emotion Regulation, Daniel R. Evans

Theses and Dissertations--Psychology

Despite having fewer cognitive resources, older adults regulate their emotions as well as, if not better than, younger adults. This study aimed to (1) test the limits of older adults’ emotion regulation capacity and (2) gain a better understanding of how older adults use their more limited resources to regulate their emotions. Participants included 48 healthy older adults aged 65-85 from the community and 50 healthy younger adults aged 18-25 from the student population. They were randomly assigned to one of four experimental groups involving an initial activity that was high or low in self-regulatory demand followed by a test …
