The Relationship Between Suicide Ideation And Parasuicide: An Electrophysiological Investigation Using The Loudness Dependence Of Auditory Evoked Potential, Angelika Marsic

Dissertations

The loudness dependence of the auditory evoked potential (LDAEP) has been proposed as a promising valid and a non-invasive indicator of behaviorally relevant central 5-HT functioning. There is limited research on the utility of the LDAEP in discriminating individuals who engage in various degrees of suicidal behavior. The primary purpose of the present study was to examine if the LDAEP, as a measure of central serotonergic functioning, can be useful in distinguishing groups of individuals who: (a) solely experience suicidal ideation (SI group); (b) experience suicidal ideation and have engaged in deliberate self-harm acts (SH group); and (c) individuals with …

The Ratio Of Positive To Negative Affect, Flourishing, And Health Behavior, Michael Stuart Leibow

Loma Linda University Electronic Theses, Dissertations & Projects

The ratio between positive and negative affect, known as the positivity ratio (PR) is thought to be associated with flourishing (psychological and social well-being). However, little research has been done on how PR and flourishing relate to specific health behaviors. The relationships between PR and flourishing with health behavior i.e., physical activity, and diet (fruit, leafy green vegetables [LGV] and meat intake) were investigated in this study. We examined whether PR mediated the relationship between flourishing and health behaviors, and whether flourishing mediated the relationship between PR and these behaviors. Gender and ethnic differences for the above associations were examined …

Genetic Associations With Borderline Personality Disorder And Related Traits And Behaviors, Casey Roy Guillot

Dissertations

Borderline personality disorder (BPD) and related traits and behaviors have been linked to a number of neurotransmitter systems, including serotonin, norepinephrine, GABA, and dopamine. Because three human single-nucleotide polymorphisms (SNPs), COMT rs4680, GABRA2 rs279871, and SNCA rs356195, have been linked to the abovementioned neurotransmitter systems, they may be associated with BPD and related traits and behaviors. The purpose of the current study is to examine associations of COMT rs4680, GABRA2 rs279871, and SNCA rs356195 with both categorical and continuous measures of BPD and with continuous measures of impulse control and self-harm in a nonclinical sample. Healthy volunteers were categorized into …

Investigating The Roles Of Time Perspective And Emerging Adulthood In Predicting Driving Behavior, Kristie L. Johnson

Psychology Theses & Dissertations

In the U.S., motor vehicle crashes are the leading cause of death for individuals 2 to 34 years of age (National Highway Traffic Safety Administration, 2009c). Of particular interest are 18 to 25 year olds or emerging adults because of their increased crash risk. The prevalence of crashes attributable to the combination of driving inexperience and risky behaviors creates the necessity to identify predictors of crash likelihoods. While there are known personality variables that predict risky driving, time perspective as an additional one was suggested. Time perspective pertains to how the past, present, and future influence an individual's actions. Zimbardo, …

The Role Of Just Desserts, Deterrence, And An Apology In Recommending Punishment For Violations Of Hiv Non-Disclosure Laws, William Alexander Woody

Psychology Theses & Dissertations

HIV non-disclosure laws, which require people with HIV to disclose their HIV serostatus to potential sexual partners, are common in the U.S. This thesis applied philosophical theories of punishment to examine why people would punish these law violators. Specifically, retribution/just deserts (i.e., an eye for an eye) and deterrence (i.e., general crime prevention) were examined as punishment motivations. Additionally, offender apology was investigated as a potential moderator of the effects of retribution on punishment. A 2 (Just Deserts) X 2 (Deterrence) X 2 (Apology) ANOVA design was used with recommendations for a prison sentence and financial fine as the dependent …

If You're Happy And You Know It: Concentrate!, Kristi Michelle Summers

Undergraduate Honors Thesis Collection

The phenomenon of mind wandering involves a situation in which a person's executive control switches from the current task to unrelated thoughts (Smallwood & Schooler, 2006). Previous research has indicated that individuals mind wander more often when they are in negative moods than when they are happier (Killingsworth & Gilbert, 2010; Smallwood, 2009). One theory of mind wandering, the Working Memory Capacity Theory, claims that participants with a lower working memory capacity (WMC) experience more mind wandering during a challenging primary task than participants with a higher WMC because those with higher WMC can better use their executive control to …

Pick-Up Lines: To Use A Neg Or A Flippant?, Adrienne Leigh Hendon

Electronic Theses and Dissertations

Pick-up lines are a "ritual that tries to turn strangers into lovers" (Murray, 1985, p.17). By studying how pick-up lines are perceived by the population, we might learn how the phenomenon of short- or long-term mating is initiated. By taking into account mating strategies, mate value, attractiveness, and flirting strategies, a pattern of behaviors and reactions may be observed. This study examines perceived pick-up line appropriateness and effectiveness when the attractiveness of the man delivering them varies. To test the effectiveness of 2 different types of pick-up lines, an online survey featuring 1 of 4 videos was administered. Results indicated …

Personality Assessment In African Elephants (Loxodonta Africana), Kristina Marie Horback

Dissertations

The following study assessed personality in twelve African elephants using both observational behavior coding and standardized trait rating methods, thus demonstrating consistent individual differences across time and contexts. During the summer of 2010 and 2011, over 640 hours of behavioral data were collected onsite at the San Diego Zoo Safari Park in Escondido, CA. Four coding-based personality traits were determined after analysis: PLAYFUL, CURIOUS, TOLERANT, and, AGGRESSIVE. This data was then compared to survey ratings completed by the animal keeper staff during both summers. Four rating-based personality traits resulted from this analysis: PLAYFUL, CURIOUS, TIMID, and, AGGRESSIVE. All eight composite …

A Multimodal Approach For The Assessment Of Alexithymia: An Evaluation Of Physiological, Behavioral, And Self-Reported Reactivity To A Traumatic Event-Relevant Video, Sarah Jo Bujarski

Graduate Theses and Dissertations

Evidence suggests alexithymia is often relatively elevated among people suffering from posttraumatic stress symptoms (PTSS). Despite a growing body of research supporting this relation between alexithymia and PTSS, it is unclear whether alexithymia is a unique predictor of emotional reactivity relative to posttraumatic stress symptoms. Furthermore, existing literature is largely limited to retrospective, self-reported symptoms. Therefore, the current study employed a multimodal assessment strategy for measuring emotional reactivity in the context of posttraumatic stress. More specifically, self-report, behavioral, and physiological measures were used to measure emotional responding to a traumatic event-related stimulus among motor vehicle accident victims. It was hypothesized …

The Role Of Self‐Injury In The Organisation Of Behaviour, Curt A. Sandman, Aaron S. Kemp, Christopher Mabini, David Pincus, Magnus Magnusson

Psychology Faculty Articles and Research

Background—Self-injuring acts are among the most dramatic behaviours exhibited by human beings. There is no known single cause and there is no universally agreed upon treatment. Sophisticated sequential and temporal analysis of behaviour has provided alternative descriptions of self-injury that provide new insights into its initiation and maintenance.

Method—Forty hours of observations for each of 32 participants were collected in a contiguous two-week period. Twenty categories of behavioural and environmental events were recorded electronically that captured the precise time each observation occurred. Temporal behavioural/ environmental patterns associated with self-injurious events were revealed with a method (tpatterns; THEME) for …

The Effects Of Personalized Boosters For A Computerized Intervention Targeting College Student Drinking, Abby L. Braitman

Psychology Theses & Dissertations

Heavy episodic alcohol use within the college student population is both widespread and problematic (Benton et al., 2004; Core Institute, 2006; Hingson, Zha, & Weitzman, 2009; O'Malley & Johnston, 2002; Perkins, 2002; Singleton, 2007). More than 40% of college students report at least one symptom of alcohol abuse or dependence (Knight et al., 2002). Computerized interventions are widely used because of their advantages over in-person interventions. They are more cost-effective and can quickly deliver tailored individual feedback to more students. Computerized interventions can be administered to large groups of students (e.g., incoming students, athletes, fraternities/sororities). However, a (2007) meta-analysis by …

The Impact Of Sleepiness And Sleep Constructs On Driving Performance, Jennifer Freeman May

Psychology Theses & Dissertations

Sleepiness causes performance decrements that lead to thousands of crashes and fatalities annually. Research supports the conclusions that sleep duration and circadian rhythms impact sleepiness and affect driving performance. Conflicting in the literature is whether severity of sleep disorders, sleep quality and subjective sleepiness affect driving performance. The correlation between a driver's perception of their sleepiness and their driving performance is also unclear. The primary goal of this study was to create an in-depth model demonstrating which measures of sleepiness influence driving performance. It was hypothesized that sleep quality, sleep apnea severity and subjective sleepiness add to a model of …

Inattentional Blindness In A Simulated Driving Task, Kellie D'Hanis Kennedy

Psychology Theses & Dissertations

The visual attention failure of inattentional blindness (IB) frequently occurs for visual information that is relevant and detectable, regardless of whether the unexpected event is congruent or incongruent within the task context. In the context of driving, an occurrence of IB has been associated with deadly collisions as well as significant property damage. For example, in 2008, drivers traveling the wrong way on clearly marked one-way roads caused 747 fatal traffic crashes. Many of these were directly attributable to inattentional blindness. Previous research focused on IB using secondary tasks such as billboards, signage, or bicyclists. The current study explored IB …

Stress Alters The Discriminative Stimulus And Response Rate Effects Of Cocaine Differentially In Lewis And Fischer Inbred Rats, Therese A. Kosten, Mindy Miserendino

Psychology Faculty Publications

Stress enhances the behavioral effects of cocaine, perhaps via hypothalamic-pituitary-adrenal (HPA) axis activity. Yet, compared to Fischer 344 (F344) rats, Lewis rats have hyporesponsive HPA axis function and more readily acquire cocaine self-administration. We hypothesized that stress would differentially affect cocaine behaviors in these strains. The effects of three stressors on the discriminative stimulus and response rate effects of cocaine were investigated. Rats of both strains were trained to discriminate cocaine (10 mg/kg) from saline using a two-lever, food-reinforced (FR10) procedure. Immediately prior to cumulative dose (1, 3, 10 mg/kg cocaine) test sessions, rats were restrained for 15-min, had 15-min …

Network-Based Criterion For The Success Of Cooperation In An Evolutionary Prisoner's Dilemma, Stephen Devlin, T Treloar

Mathematics

We consider an evolutionary prisoner's dilemma on a random network. We introduce a simple quantitative network-based parameter and show that it effectively predicts the success of cooperation in simulations on the network. The criterion is shown to be accurate on a variety of networks with degree distributions ranging from regular to Poisson to scale free. The parameter allows for comparisons of random networks regardless of their underlying topology. Finally, we draw analogies between the criterion for the success of cooperation introduced here and existing criteria in other contexts.

Thank You, Dear: Examining The Association Between Gratitude And Relationship Well-Being, Erica Pearse Ragan

Electronic Theses and Dissertations

The current study replicated and extended existing research on gratitude by examining the ways in which gratitude is related to both individual and relationship well-being. A total of 387 participants completed the pre assessment and were randomized into the study, with 251 participants completing the full study (i.e., pre, post, and follow-up assessments). Participants were randomly assigned to list relationship-focused gratitudes, amusing events, or general events that happened during their day for 14 days. The differential impact of the three interventions on both individual and relationship variables was investigated. The relationship-focused and general events conditions experienced decreased negative affect from …

Trauma In Transportation: Factors Contributing To Positive And Negative Outcomes Of Involvement In Trauma For Railroad Workers, Jill Veronica Pinarowicz

Electronic Theses and Dissertations

This study explored several predictors of Post Traumatic Stress Disorder (PTSD) and Post Traumatic Growth (PTG) in a sample of 136 train employees. The first objective was to examine the influence of number of work related traumas, number of life traumas, age, personality characteristic extroversion, personality characteristic openness, social support, positive cognitive coping, and negative cognitive coping in the prediction of PTSD. The second objective was to assess the influence of number of work related traumas, number of life traumas, age, personality characteristic extroversion, personality characteristic openness, social support, positive cognitive coping, and negative cognitive coping prediction of PTG.

Understanding Jurors’ Judgments In Cases Involving Juvenile Defendants: Effects Of Confession Evidence And Intellectual Disability, Cynthia J. Najdowski, Bette L. Bottoms

Psychology Faculty Scholarship

Juveniles are at heightened risk for falsely confessing to crimes, particularly if they are intellectually disabled. We conducted a mock trial experiment to investigate the effects of a juvenile defendant’s confession and status as intellectually disabled on jurors’ decision making. As expected, jurors discounted a juvenile’s coerced confession: Jurors’ judgments were similar for a juvenile who was perceived to have confessed under coercion and a juvenile who did not confess. In general, these effects were explained by the fact that, compared to a juvenile who was perceived as having confessed voluntarily, a juvenile who was perceived as having confessed under …

The Mythology Of Game Theory, Mathew D. Mccubbins, Mark Turner, Nick Weller

Faculty Scholarship

Non-cooperative game theory is at its heart a theory of cognition, specifically a theory of how decisions are made. Game theory's leverage is that we can design different payoffs, settings, player arrays, action possibilities, and information structures, and that these differences lead to different strategies, outcomes, and equilibria. It is well-known that, in experimental settings, people do not adopt the predicted strategies, outcomes, and equilibria. The standard response to this mismatch of prediction and observation is to add various psychological axioms to the game-theoretic framework. Regardless of the differing specific proposals and results, game theory uniformly makes certain cognitive assumptions …

The Theory Of Minds Within The Theory Of Games, Mathew D. Mccubbins, Mark Turner, Nicholas Weller

Faculty Scholarship

Classical rationality as accepted by game theory assumes that a human chooser in a given moment has consistent preferences and beliefs and that actions result consistently from those preferences and beliefs, and moreover that these preferences, beliefs, and actions remain the same across equal choice moments. Since, as is widely found in prior experiments, subjects do not follow the predictions of classical rationality, behavioral game theorists have assumed consistent deviations from classical rationality by assigning to subjects certain dispositions— risk preference, cognitive abilities, social norms, etc. All of these theories are fundamentally cognitive theories, making claims about how individual human …

Motivation, Need Support And Need Satisfaction In Youth Soccer Players, Erica Lippitt

College of Graduate Studies: Theses & Dissertations

Author's abstract: Physical activity levels and obesity rates vary greatly across ethnic groups in the United States (CDC, 2011). One popular way to increase physical activity levels in youth is through youth sport participation, which may be influenced by athlete motivation. Numerous studies have determined motivation levels in youth sport participants, but very little done in comparing levels across different ethnic groups. Identifying differences in motivation levels based on ethnicity can allow coaches and sport administrators to adjust practices and program setups to increase participation and meet needs of player competence. The purpose of the study was to determine if …

Predictors Of Bullying In An Adolescent School Sample, Schell Hufstetler

College of Graduate Studies: Theses & Dissertations

Author's abstract: Bullying is a pervasive problem in our society. Contributing to this problem is the fact that bullying is not well understood. This makes it difficult to design successful interventions. The current study aims to create a complete picture of bullying in order to increase understanding of this behavior. For this study, 59 adolescents completed a survey packet including measures of bullying behaviors and other variables expected to relate to bullying. The results revealed that bullying is a problem for both genders. Multivariate analyses revealed males to be more directly and indirectly aggressive, but there were no significant gender …

When Cognitive Bias Masquerades As Intervention Efficacy: Drinking Norms As Anchors And Norm Interventions As Anchoring Effects, Matthew R. Pearson

Psychology Theses & Dissertations

Problematic drinking is a serious public health concern on college campuses in the United States. College students most frequently report drinking for social reasons, and perceptions of peers' drinking, or perceived drinking norms, are among the most consistent, robust predictors of college student drinking. Therefore, norm-based interventions have risen to prominence in the attempt to reduce the harm caused by college student alcohol use. However, the efficacy of these interventions may be obscured by cognitive bias. Specifically, providing information regarding the drinking norm may "anchor" individuals' estimates of their own behavior. Using samples of college student drinkers, two studies were …

Amygdalar Stimulation Produces Alterations On Firing Properties Of Hippocampal Place Cells, Eun Joo Kim, Earnest S. Kim, Mijeong Park, Jeiwon Cho, Jeansok J. Kim

Faculty Publications - Psychology Department

Stress is a biologically ubiquitous factor that, when perceived uncontrollable by humans and animals, can have lingering adverse effects on brain and cognitive functions. We have previously reported that rats that experienced inescapable-unpredictable stress subsequently exhibited decreased stability of firing rates of place cells in the CA1 hippocampus, accompanied by impairments in CA1 long-term synaptic potentiation and spatial memory consolidation. Because the elevated level of glucocorticoid hormones and the heightened amygdalar activity have been implicated in the emergence of stress effects on the hippocampus, we investigated whether administration of corticosterone and electrical stimulation of the amygdala can produce stress-like alterations …

A Punishment-Free, Toilet-Training Protocol For Children With Developmental Disabilities, Chelsea Lynn Pearsall

All Master's Theses

The present investigation adapted a behaviorally-based toilet-training protocol for use with two male children with developmental disabilities. Positive practice and verbal reprimands were eliminated, and reinforcement, scheduled sits, and a urine alarm were utilized. Data were collected on the number of intoilet urinations, urinary accidents, and self-initiations. Results show that both participants exhibited significant improvement in their toileting skills and met the final success criteria rapidly. These results were maintained through follow-up. Implications for the elimination of punishment procedures in future toilet training protocols are discussed.

Mood And Creativity: The Mediating Role Of Attention, Viktoria Tidikis

Psychology Theses & Dissertations

Within literature there are two opposing views regarding the role of emotions in the creative process. The most commonly held view contends that positive emotions enhance creativity, while negative emotions stifle it; yet, some studies show an opposite trend. To help resolve this conundrum, this research examined the mediating effect of attention on the relationship between mood and creativity. The results showed that positive deactivating and negative activating emotions led to broader attention, while positive activating and negative deactivating emotions caused narrowing of attention. Furthermore, the creative process is not uniform in its requirements of attentional breadth; some creative tasks …

Conditioned Response Evoked By Nicotine Conditioned Stimulus Preferentially Induces C-Fos Expression In Medial Regions Of Caudate-Putamen, Sergios Charntikov, Matthew E. Tracy, Changjiu Zhao, Ming Li, Rick A. Bevins

Department of Psychology: Faculty Publications

Nicotine has both unconditioned and conditioned stimulus properties. Conditioned stimulus properties of nicotine may contribute to the tenacity of nicotine addiction. The purpose of this experiment was to use neurohistochemical analysis of rapidly developing c-Fos protein to elucidate neurobiological loci involved in the processing of nicotine as an interoceptive conditioned stimulus (CS). Rats were injected (SC) in an intermixed fashion with saline or nicotine (16 sessions of each) and placed in conditioning chambers where they were given one of the three conditions depending on group assignment: (a) nicotine paired 100% of the time with intermittent access to sucrose (nicotine-CS condition), …

Development And Hope: Comments On Thomas Mccarthy's Race, Empire, And The Idea Of Human Development, Ladelle Mcwhorter

Philosophy Faculty Publications

Thomas McCarthy’s Race, Empire, and the Idea of Human Development is an intriguing and important book; moreover, despite its heavy themes and its fine scholarship, it is extremely readable. And it is very timely. The questions it takes up are some of the most pressing of our age: globalization, international distributive justice, and sustainable economic development in particular. Its central problematic concerns the detrimental effects of developmental thinking as a core feature of modernity. The book seeks, says McCarthy, to make “a contribution to the critical history of the present” (2), but it does not stop with critical analysis; McCarthy …
