Parental Factors Impacting Neurobehavioral Late Effects In Latino Pediatric Cancer Survivors, Pamela R. Perez

Loma Linda University Electronic Theses, Dissertations & Projects

While the survival rate for children with cancer has increased markedly over the past 50 years, the side effects resulting from cancer and cancer treatment have become a major concern for health care providers and families alike. Survivors of childhood cancers are at risk for late occurring sequelae, called late effects, which are associated with disease, chemotherapy, radiation, and surgery. Neurobehavioral late effects are some of the most debilitating late effects found, particularly in survivors of central nervous system (CNS) cancers. The purpose of this study was to explore the impact of clinical and socio-demographic parenting factors on neurological late …

The Effects Of Observers’ Expectations And The Probability Of A Change Occurring On Change Detection Performance, Robert A. Brown

Doctoral Dissertations and Master's Theses

The change probability effect is a term coined by Beck et al. (2004) and it suggests that changes that are expected or "probable" are detected more easily than changes that are unexpected or "improbable". This research study investigates the change probability effect and the differences between observers who are looking for changes and those who are unaware that changes may exist. The results suggest that observers who are not expecting a change to occur are more likely to detect an improbable change than a probable change. The findings from this study have real world applications and also have implications for …

The Relations Among Laterality, Cortisol, And Approach-Avoidance Behavior In Garnett's Bushbaby (Otolemur Garnettii), David Burton Hanbury

Dissertations

Many studies to date have demonstrated that approach and avoidance behaviors are processed asymmetrically in the brain and may be reflected in measures such as handedness. The purpose of this study was to extend work in primates on this topic to Garnett’s bushbaby, a prosimian species. Furthermore, to determine whether measures in addition to handedness relate to approach-avoidance behavior, lateralized differences in tympanic membrane temperature were assessed. Cortisol measures were also obtained to determine whether it was related approach-avoidance behavior and handedness. Eleven captive-born Garnett’s bushbabies (Otolemur garnettii) were evaluated for handedness and responsiveness to novelty. Moreover, the …

Individual Differences In Zebrafish (Danio Rerio) Behavior: Implications For Personality, Christina Nicole Toms

Master's Theses

Individual differences (IDs) in zebrafish (Danio rerio) behavior were examined across time and contexts in order to investigate personality traits. Zebrafish (N = 30) were exposed to six behavioral tasks that were collectively expected to capture (a) aggression, (b) boldness/shyness, and (c) fear. The tasks included a small open field, mirror exposure, emergence, large open field, novel object, and predator exposure tasks. IDs in behavior were found to be consistent across time for a majority of behaviors and consistent across contexts for all but two behaviors. Convergent and discriminate evidence was examined for the three constructs. There was …

The Effect Of Improvisations And Observations On Standardized Patient Encounters, Subjective Workload And Stress, Elizabeth T. Newlin-Canzone

Psychology Theses & Dissertations

Standardized patients (SPs) are people trained to present a medical case for teaching and assessing medical students and they simultaneously perform several demanding tasks including portraying the patient, assessing the learner, and providing feedback. This study investigated the effect of improvisations and multiple task performance on the ability to observe another's nonverbal (NV) behaviors and rate their communication skills. Subjective reports of mental workload and stress were also obtained. The first study involved undergraduates interviewing for a job. Type of interview (rote and improvisational) and type of observation (passive and active) were manipulated within groups. Based on theories of attention …

Childhood Depressive Symptoms: Comparison Of Diverse Medical Diagnoses, Ida Babakhanyan

Loma Linda University Electronic Theses, Dissertations & Projects

Childhood depression is a serious problem and has long term implications including increased risk for suicide and comorbid conditions. In addition, depressed children are at greater risk for social difficulties, non-compliance to medical regime, and academic difficulties. Children undergoing a medical illness are at increased risk for developing depression, however, there have been few recent studies looking at emotional distress for this population. With thousands of children hospitalized every day, assessing for depressive symptoms is important in order to provide proper referrals and treatment recommendations following discharge. The purpose of the current study was to increase understanding of pediatric depression …

The Structure Of Equine Personality, Rachel Etta Kristiansen

Dissertations

The current study was designed to investigate the structure of equine personality. Two personality questionnaires were replicated from previous studies and implemented simultaneously to test the theory that different questionnaires may extract different personality structures. Breed and sex differences were also hypothesized to be significantly different for some personality dimensions. A total of 827 horses were rated on a 90-item personality questionnaire. Participants were recruited online via email and completed the survey at their own convenience. An additional 121 respondents rated a horse that had already been rated; these results were used to calculate inter-rater reliability.

After data collection was …

A Field Experiment To Test The Effects Of Automated Feedback And Monetary Incentive On Speeding Behavior, Ian J. Reagan

Psychology Theses & Dissertations

This field experiment tested the effects of two systems on speeding, mental workload, and driver acceptance of the systems. Using GPS technology integrated with GIS referenced speed limit information, eight vehicles were instrumented in a manner that allowed real time knowledge of vehicle speed relative to the speed limit. Fifty participants drove these vehicles, with each individual driving his or her assigned vehicle for a four week trial. During one week, 40 participants experienced an automated feedback system, which provided visual and auditory alerts when they sped five or more mph over the limit. Twenty of these 40 individuals experienced …

Effects Of Mood On Using Analogies To Solve Problems And Reduce Conflict, Erin Good

Undergraduate Honors Thesis Collection

Past research has shown that analogies and metaphors can be useful tools in problem solving tasks (e.g., Gick & Holyoak, 1980). In addition, mood has been shown to have an effect on a person’s ability to generate solutions to problems (Abele, 1992). The present study was designed to investigate how mood affects analogical problem solving, especially in relation to conflict resolution. I examined whether mood has the same effect on the use of analogies to solve interpersonal conflict problems as it does on the use of analogies to solve cognitive problems. In this experiment, participants began by writing about an …

Are We Becoming Superhuman Cyborgs? How Technomorphism Influences Our Perceptions Of The World Around Us, Heather Christina Lum

Electronic Theses and Dissertations

Although traditionally researchers have focused on making robotics more user-friendly from a human perspective, a new theory has begun to take shape in which humans take on the perspective of a robotic entity. The following set of studies examined the concept of technomorphism defined as the attribution of technological characteristics to humans. This concept has been mentioned anecdotally and studied indirectly, but there is nothing currently available to tap in to the various forms that technomorphism may take. Therefore, one goal of this dissertation was to develop a scale to fill that purpose. The results of the Technomorphic Tendencies Scale …

Comparing Conscientiousness And Neuroticism In Predicting Task Performance And Contextual Performance, Lu Qin

Theses Digitization Project

The primary aim of this proposal is to address the relationship of effort intensity to neuroticism in predicting task performance and compare conscientiousness and neuroticism in predicting task performance and contextual performance. Building on previous studies' results, Big Five personality factors were examined as correlates of job performance. A pilot survey was distributed to a total of 251 participants who were working at least 20 hours a week collected from five organizations in the Los Angeles area.

Self-Regulation Among Highly Prejudiced People: A Tool For The Amelioration Of Racial Bias, Kristina L. Silverbears

WWU Graduate School Collection

The source of motivation to respond without prejudice varies among individuals and is connected to their evaluations of biased materials. People who are highly internally motivated to respond without prejudice tend to be lower in prejudice than are people who are highly externally motivated. High internal motivation is typically associated with less biased responding, but when bias does occur feelings of self-directed negative emotions often result. For low prejudice people these self negative feelings can lead to a system of responses culminating in future self regulation. The same self-negative feelings do not function identically for people who are higher in …

Self Discrepancy And Narrative Repair, Lauren E. Jennings

WWU Graduate School Collection

Personal narratives have been shown to play an important role in creating a stable sense of self, yet little research has examined this in experimental designs. Thus, this study explored the utility of narrative, in comparison to other mechanisms (e.g., self-affirmation, distraction), for coping with threats to self-concept by examining affective and cognitive repair after experiencing a threat. Participants (N = 331) received false physiological feedback suggesting a prejudiced response to African Americans and obese people and were induced to complete one of five repair techniques. Participants also completed affect and self-concept measures pre-study, post-threat, and post-repair. Overall, threat-specific and …

Measuring Smoking-Related Attentional Bias With A Change Detection Task, Gordon T. Barker

WWU Graduate School Collection

Despite well known health risks, cigarette smoking remains very prevalent in the United States. In addition, those who attempt to quite are very likely to relapse. Cognitive predictors have not been well examined to date, despite evidence from the Incentive- Sensitization model of addiction that cognitive processes play a large role in relapse and continued addictive behavior (Robinson & Berridge, 1993). To address if the cognitive adaptations involved in the Incentive-Sensitization model are permanent or semi-permanent, this current study examined the abilities of current smokers (n = 15), former smokers (n = 13), and never smokers (n = 15) to …

Bis-Bas, Dispositional Influences On Cardiac Reactivity To Naturally Occurring Stressors, Nicholas P. (Nicholas Peter) Goodman

WWU Graduate School Collection

Research has relied primarily on laboratory settings to examine how emotions and physiology are affected by acute experiences of stress. This is because it is difficult to manipulate acute stress outside the lab and without a discrete manipulation it is difficult to measure physiological and emotional arousal during acute stress. This study found evidence that everyday stress predicts temporary changes in blood pressure. The purpose of this study was to investigate Gray's (1987) behavioral inhibition (BIS) and behavioral activation (BAS) systems, and to identify divergent cardiovascular and emotional outcomes to natural stressors for each of these systems. The data from …

Testing The Effectiveness Of An Interactive Multimedia System To Train Clinicians In Behavioral Activation, Suzanne E. Decker

Dissertations

Although many treatments for mental health disorders have been found to be effective in research, community clinicians may not receive training in such empirically supported treatments, and therefore, individuals suffering from disorders may not have access to empirically supported treatment in the community. This study examined the use of an interactive multi-media computerized therapy program, Building a Meaningful Life through Behavioral Activation, as a training tool for mental health clinicians (N=21) using a pre-post study design. Participating clinicians were invited to complete this computer program over the course of several weeks, and to complete knowledge quizzes and written responses …

The Effects Of Yellow Rectangular Rapid-Flashing Beacons (Rrfbs) Onmotorists' Yielding, Exit Lane Encroachment And Conflicts At Fire Station Exits, Erick K. Marmolejo

Dissertations

The purpose of the current study was to explore the extent to which yellow rectangular rapid-flashing beacons (RRFBs) affected motorists' yielding, exit-lane encroachment and conflicts at fire station exits. This study explored the use of RRFBs attached to sign prompts that alerted motorists to the presence of exiting emergency vehicles. These signs were activated only during an exit event. It was hypothesized that motorists would increase their frequency of safe and legal yielding in the presence of the RRFB intervention when compared to the absence of contextually activated RRFB units. This study was conducted in a midwestern town in front …

Dosed Versus Prolonged Exposures: A Direct Comparison Of One-Session Treatments For Animal Phobias, Richard William Seim

Dissertations

It is widely accepted that for exposure-based therapies to be effective feareliciting stimuli must be presented continuously until there is a marked decrease in the client's anxiety (e.g., Eysenck, 1979; Foa & Kozak, 1986). However, an emerging body of research (cf. Seim, Waller, & Spates, 2010) suggests that a massed series of very brief exposures (< 150 sec) may be effective in the extinction of fear responses. The present study was designed to compare the efficacy and acceptability of two one-session treatments for animal phobias: one that utilized continuous, uninterrupted periods of exposure to a feared animal (Prolonged Exposures) and the other that utilized a massed series of brief (5-120 sec) exposure trials (Dosed Exposures). 24 adults (7 males, 17 females) between the ages of 18 and 57 years (M = 23.6) participated in this study. Each individual met DSM-IV criteria for a diagnosis of snake phobia or spider phobia. Participants were randomly assigned to one of two the two interventions. Both treatments required participants to gradually enter a room, approach, and eventually hold a live ball python or tarantula. Results from mixed model (between x within subjects) analyses of variance showed that the Dosed Exposure treatment performed equally well to Prolonged Exposures at decreasing behavioral avoidance, feelings of anxiety, perceptions of threat, and phobiaspecific cognitions from pre-treatment to post-treatment, and these gains were maintained at one-week follow-up. Although participants receiving Prolonged Exposures reported lower ratings of within-session anxiety, participants in the Dosed Exposure group had lower rates of treatment dropout, better compliance with procedures, and fewer safety-seeking behaviors during the treatment. These findings suggest that, contrary to popular belief, brief exposure trials can be effective in the extinction of phobic responses under certain conditions.

Differences In Anti-Fat Attitudes Among Healthcare Providers And General Students, Jessica C. Silks

WWU Graduate School Collection

Weight bias is prevalent, detrimental, and resistant to change. This study provided a general student sample and a healthcare provider sample with information about behavioral, environmental, or biogenetic causes of obesity to compare resulting anti-fat attitudes. Across conditions, the healthcare providers were less likely to agree that obesity is personally controlled, and demonstrated more positive implicit attitudes than did the general students. Among general students, implicit anti-fat attitudes were impervious to reduction efforts across article conditions. Among healthcare providers, implicit anti-fat attitudes improved with biogenetic explanations and did not worsen with behavioral explanations relative to the control group. No such …

Digit Ratios, Baron-Cohen's Reading The Minds In The Eyes And Dart-Throwing Task, Betul Zora

Honors Program Theses

There is evidence that high prenatal testosterone and the ratio of the index finger to the ring finger are correlated. There is also evidence that male-typical finger ratios correlate positively with male-typical tasks such as targeting and negatively correlated with female-typical tasks. This study examines the correlation between the digit ratio and the dart throwing task and also the digit ratio and Baron-Cohen’s Reading the Mind in the Eyes test. A different digit ratio, the ratio of the index finger and the ring finger to the pinky is also collected and correlated with both of the other tests. Sometime during …

A Research Study Examining Forgiveness, Empathy, Commitment, Trust, And Relational Satisfaction Among Adult Friends After Relational Transgressions, L. Lori Poole

Electronic Theses and Dissertations

This research project examined how forgiveness was managed by adult friends after relational transgressions. It studied how the emotion of empathy promoted the act of forgiving and why the construct of commitment related to trust and relational satisfaction among friendship dyads. Isolating the specific emotion empathy in regards to forgiveness heightened the understanding of what emotional behaviors were used to maintain friendships once a relational transgression was experienced. Measuring and analyzing the interaction between commitment, trust, and relational satisfaction helped to determine how these constructs promoted forgiveness among adult friends.

Family Involvement Within Assisted Living: Care-Receivers' And Caregivers' Roles And Relationships, Rachel Vineet Solomon

Electronic Theses and Dissertations

Family systems providing informal care and support to their aging relatives, who were residing in assisted living systems and receiving formal care were central to this study. A broader understanding of family involvement, with respect to exploring both care-receiver and caregiver roles and relationships, within the regulatory and environmental context of assisted living was sought through a qualitative research process. This study employed a phenomenological approach to conduct in-depth interview sessions with eight pairs of participants, comprising elderly residents in five assisted living facilities and their respective caregiving family members, typically a daughter or son and, in one case, a …

Assessing The Effects Of A Rectangular Rapid-Flashing Beacon On Vehicle Speeds Along A Four-Lane Divided Highway, Michelle Van Wagner

Dissertations

In 2008, nearly 31% of vehicle fatalities were related to failure to adhere to safe vehicle speeds (National Highway Traffic Safety Administration (NHTSA), 2009). Two studies were conducted to evaluate the effects of a Rectangular Rapid-Flashing Beacon (RRFB) triggered by excessive speed on vehicle speed using a combined alternating treatments and reversal design. Experiment 1 assessed the RRFB's impact on speeds as compared to baseline conditions only. Experiment 2 compared the RRFB to two standard beacon configurations. Both experiments were conducted at the same site during approximately the same time period and both employed the same data collection methodology. The …
