Dismantling An Act-Based Intervention For Work Stress: Do Values Really Matter?, Barbara A. Hermann
Dismantling An Act-Based Intervention For Work Stress: Do Values Really Matter?, Barbara A. Hermann
Electronic Theses and Dissertations
Acceptance and Commitment Therapy (ACT), a multi-component intervention within the third-wave of behavioral therapy, has been shown to improve various outcomes in diverse populations and administration formats. This study utilized a dismantling design to investigate whether the values components of an ACT-based intervention for work stress add to the effects of the intervention beyond those of the mindfulness components and to explore possible mediators of change. Expanding beyond existing studies of ACT, a broad range of outcomes were examined pretreatment, post-treatment, and at three follow-up assessments in a small sample (N = 16) of employees of a university in the …
Evaluation Of A Progressive Model For Identifying Preferred Stimuli For Children With Developmental Disabilities, Amanda M. Karsten
Evaluation Of A Progressive Model For Identifying Preferred Stimuli For Children With Developmental Disabilities, Amanda M. Karsten
Dissertations
Preference assessments for individuals with disabilities differ along many dimensions, including time requirements for implementation and probability of identifying a hierarchy of relative preferences. Some methods of assessment are also more conducive to use with individuals who exhibit problem behavior or certain prerequisite skills. Inaccurate results and loss of valuable treatment time are among the risks associated with selecting ineffective or unnecessarily lengthy procedures. The purpose of the current investigation was to evaluate a progressive model for conducting preference assessments which incorporates many of the aforementioned considerations. Concurrent-operant reinforcer evaluations were used to verify assessment findings. Based on 17 participants …
The Relationship Between Valuing Diversity And Implicit Racial Bias: A Construct Validation Study, Rebekka Althouse Gordon
The Relationship Between Valuing Diversity And Implicit Racial Bias: A Construct Validation Study, Rebekka Althouse Gordon
Psychology Theses & Dissertations
Two studies examined the construct validity of valuing diversity in relation to both explicit and implicit racial bias. In the first study, participants completed three measures: the Miville-Guzman Universality-Diversity Scale to measure valuing diversity; the Implicit Association Test to assess implicit racial bias; and the Symbolic Racism 2000 Scale to assess explicit racial bias. Results indicated there was a significant relationship between the valuing diversity and implicit racial bias measures as well as between the valuing diversity and explicit racial bias measures. The explicit and implicit racial bias measures accounted for unique variance in the valuing diversity construct. There was …
Factors That Affect Performance On Executive Functioning After Coronary Artery Bypass Grafting, Sapna Mahesh Patel
Factors That Affect Performance On Executive Functioning After Coronary Artery Bypass Grafting, Sapna Mahesh Patel
Loma Linda University Electronic Theses, Dissertations & Projects
Research suggests that individuals who undergo coronary artery bypass grafting (CABG) experience declines in neuropsychological functioning post-operatively. This decline has been observed in up to 80% of patients early after surgery, and in up to 30% of patients after six months. Many studies have examined the potential effects of CABG on neuropsychological functioning in general, and numerous studies have found that executive functions are impaired in particular. However, none have examined what factors contribute to observed executive dysfunction after CABG. This study investigated the role of memory functions on executive functions in a selected sample of patients undergoing CABG. This …
Predicting Long-Term Memory In Adult Brain Injury Patients Using Mr Spectroscopy, Herminia De La Rosa-Trujillo
Predicting Long-Term Memory In Adult Brain Injury Patients Using Mr Spectroscopy, Herminia De La Rosa-Trujillo
Loma Linda University Electronic Theses, Dissertations & Projects
Accurate outcome prediction has proven to be somewhat elusive for patients with traumatic brain injury (TBI). The difficulty is due to the sometimes inaccurate methods of prediction currently available. Despite the advances seen in radiological technology, the traditional methods of x-rays, CT scans and MRIs are not always accurately able to predict patient functional outcome. These radiological methods are adequate in determining gross structural anatomical disturbances, however, they unable to detect more diffuse cellular damage believed to be responsible for the functional impairments evidenced in patients sustaining TBI. Magnetic Resonance Spectroscopy (MRS) is an imaging technique which measures brain metabolites …
The Effect Of Computer-Based Biofeedback On Creativity, Qin Li
The Effect Of Computer-Based Biofeedback On Creativity, Qin Li
Honors Capstone Projects - All
In recent decades, Psychology has advance empirical studies of creativity, aiming for a better and more concrete understanding of this elusive topic. One branch of these studies investigates creativity’s physiological manifestation in an attempt to isolate underlying neurophysiologic mechanisms involved in creative thinking. These studies, through EEG recording of electrical brain activity, indicated that highly creative individuals tend to express a low arousal state as compared to less creative individuals. This experiment investigates the relationship between induced low arousal and creativity. A computer-based biofeedback game is used to induce low arousal. A multivariate analysis of our data revealed no significant …
Developing Lexical Competition Resolution Mechanisms Through Reading Experiences, Ana B. Areas Da Luz Fontes
Developing Lexical Competition Resolution Mechanisms Through Reading Experiences, Ana B. Areas Da Luz Fontes
Open Access Theses & Dissertations
The goal of the present study was to investigate whether competition resolution mechanisms are improved throughout a student's college years. For this purpose, I bilingual participants with a range in the number of college credits completed (e.g., freshmen to seniors) were recruited. Participants were presented with sentences that biased the less frequent, or subordinate meaning of an ambiguous word (e.g., novel, fast) (e.g., novel: something new; fast: to not eat). The ambiguous word was either a Spanish-English cognate (e.g., novel/novela) or a noncognate control (e.g., fast). These sentences were followed by target words that, on critical trials, were related to …
The Effects Of Using A Scripted Or Unscripted Interview In Forensic Interviews With Interpreters, Nicole Pruss
The Effects Of Using A Scripted Or Unscripted Interview In Forensic Interviews With Interpreters, Nicole Pruss
Open Access Theses & Dissertations
The current study set out to replicate and expand the results of a study by Pruss (2007) which found that information is lost when interviews are conducted through interpreters. In the present study, Viewers (i.e., mock eyewitnesses) fluent in Spanish watched a video of a burglary and then were interviewed in Spanish about what they had seen. Half of Viewers were randomly assigned to be interviewed by an English-speaking Interviewer through a bilingual Interpreter (Interpreter condition), and the other half were randomly assigned to be interviewed directly by a Spanish speaking Interviewer with no Interpreter (No Interpreter condition). Within each …

The Relationships Between Cyber And Non-Cyber Bullying And Depressive Symptoms Among Adolescents In Western Australia, Mitch J. Read
The Relationships Between Cyber And Non-Cyber Bullying And Depressive Symptoms Among Adolescents In Western Australia, Mitch J. Read
Theses : Honours
Much research has explored the nature, prevalence and impact that bullying behaviours have on children and adolescents. Correlations have been found between bullying behaviours and depression, suicidal ideation, anxiety, loneliness, psychosomatic symptoms and conduct disorders. With a rapid increase in the availability and use of information and communication technologies young people are now able to bully others in a relatively anonymous, removed fashion, often referred to as cyber bullying. This paper provides a review of the research that has investigated the nature, prevalence and impact of cyber and non-cyber bullying. The bullying literature highlights the negative consequences this behaviour often …
Context Processing As A Function Of Anxiety Level, Viara Ivanova Stankova
Context Processing As A Function Of Anxiety Level, Viara Ivanova Stankova
Theses Digitization Project
The present study aims to establish a direct link between insufficiences in context processing and cognitive deficits related to anxiety symptoms and thus enhance the overall understanding of the underlying mechanisms of the observed discrepancies in cognitive performance. The goal of the present investigation was to apply Braver's model of cognitive control to groups selected on their differences in trait anxiety and explore their relationship. The main goal is to demonstrate that Braver and colleagues context processing theory of cognitive control provides a parsimonious explanation of processing deficits found in those showing anxiety symptoms. A total of 458 Cal State …
Ho'oponopono: Assessing The Effects Of A Traditional Hawaiian Forgiveness Technique On Unforgiveness, Matthew B. James
Ho'oponopono: Assessing The Effects Of A Traditional Hawaiian Forgiveness Technique On Unforgiveness, Matthew B. James
Walden Dissertations and Doctoral Studies
This study expanded on the existing empirical research on forgiveness and specifically ho'oponopono, a traditional Hawaiian forgiveness process. An extensive literature review revealed that while forgiveness has gained in popularity among researchers and clinicians, few therapeutic process-based models have been researched. Furthermore, ho'oponopono has not been studied as a process-based approach to forgiveness. Therefore, the purpose of the present between-groups, within-groups, repeated measures study was to assess the effects of the application of ho'oponopono (focused on a specific transgressor) on levels of unforgiveness, as measured by the Transgression-Related Interpersonal Motivations Inventory (TRIM). The participants (N = 79) were randomly divided …
The N400 Erp: Semantic Vs. Evaluative Incongruities, Jennifer Hilda Taylor
The N400 Erp: Semantic Vs. Evaluative Incongruities, Jennifer Hilda Taylor
Open Access Theses & Dissertations
The objective of this research was to utilize both behavioral (response times) and psychophysiological measures (ERPs - N400 & Pre-response Positivity) to uncover the cognitive mechanism responsible for the evaluative priming effect (spreading activation vs. response competition) by controlling for semantic influences. This research project examined the evaluative incongruity effect by controlling for semantic influences in two separate studies. The first study kept semantic associations among word pairs completely random, while the second study controlled for semantic associations by either pairing words from the same semantic category (e.g., animal-animal) or from different semantic categories (e.g., animal-person). Participants completed an evaluative …

Self-Efficacy, Sense Of Belonging And Social Support As Predictors Of Resilience In Adolescents, Anna Nowicki
Self-Efficacy, Sense Of Belonging And Social Support As Predictors Of Resilience In Adolescents, Anna Nowicki
Theses : Honours
Adolescence has been described as a period of many physical, cognitive and psychosocial changes. During such a tumultuous time some adolescents cope better than others with life stressors, and these individuals can be considered resilient. The degree to which a person is resilient can be influenced and determined by protective factors, including social support, sense of belonging and self-efficacy. Positive social support has been identified as a buffer that protects individuals from the negative effects of stressful life situations. A strong sense of belonging has positively reflected adolescents' motivation, participation and ability to relate to their environment. Self-efficacy has also …
A Phenomenological Study Of Foster Carers' Experiences Of Formal And Informal Support, Tara Cavazzi
A Phenomenological Study Of Foster Carers' Experiences Of Formal And Informal Support, Tara Cavazzi
Theses : Honours
Foster children are showing a higher prevalence of maladaptive physical and psychosocial issues than ever before. The presence of these issues is predictive of foster placement instability, which is compounded by the inability to recruit and retain foster carers. As placement disruption can have numerous consequences, the factors that influence placement stability have been reviewed. Carer strain is a widespread destabilizing factor, which is augmented by many factors including the perceived level of practical and emotional support from both formal and informal networks. Formal support is linked to placement stability, although carers generally feel undervalued and unappreciated by formal networks. …
The Dimensionality Of Emotion And Individual Differences, Leah Braganza
The Dimensionality Of Emotion And Individual Differences, Leah Braganza
Theses : Honours
This paper is a critical review of the research on the relative contribution of valence and arousal to the effect of emotion on performance. It is well accepted that emotion influences aspects of cognitive performance, but there are inconsistent results concerning the relative salience of valence and arousal. Some authors support the idea that valence, rather than arousal, is the primary contributor to this effect of emotion on performance. This review analysed the methodology used in studies supporting the primary role of valence, and this analysis revealed that the two dimensions may have been confounded. The literature suggested that arousal …
Trips Down Memory Lane: Recall Direction Affects The Subjective Distance Of Past Events, Kent C.H. Lam
Trips Down Memory Lane: Recall Direction Affects The Subjective Distance Of Past Events, Kent C.H. Lam
Theses and Dissertations (Comprehensive)
The subjective temporal distance of a past event—how close or far away it feels—is influenced by numerous factors apart from actual time. The present studies extend research on subjective distance by exploring the experience of remembering autobiographical events as part of a stream of related events. It is proposed that a key determinant of subjective distance is the temporal direction in which events are recalled. Five experiments supported the hypothesis that people feel closer to a target event when they recall a stream of related events in a backward direction (i.e., a reverse-chronological order ending with the target event) rather …
Pigeons’ Memory For Time: Assessment Of The Role Of Subjective Shortening In The Duration Of Comparison Procedure, Patrick Van Rooyen
Pigeons’ Memory For Time: Assessment Of The Role Of Subjective Shortening In The Duration Of Comparison Procedure, Patrick Van Rooyen
Theses and Dissertations (Comprehensive)
In Experiment 1, pigeons were trained with a 1-s baseline s-c delay in a duration comparison procedure to peck one key if a comparison duration (c) was 1-s shorter than a standard duration (s), and another key if c was 1-s longer than s. The duration pairs used prevented pigeons from relying on the absolute duration of c on some trials (comparison common) while on other trials they could rely on the absolute duration of c (comparison unique). Pigeons were then tested with equal duration pairs at extended s-c delays of 1, 2, 4, and …
The Role Of Sex, Gender Role, And Extraversion-Introversion In Explaining The Experience, Expression And Control Of Anger, James Oliver
The Role Of Sex, Gender Role, And Extraversion-Introversion In Explaining The Experience, Expression And Control Of Anger, James Oliver
Theses : Honours
Anger is a frequently experienced emotion that has been shown to influence perceptions, beliefs, ideas, reasoning, and ultimately choices and actions. It has the potential to become a serious problem if it reaches dysfunctional levels. This study examines the role of biological sex, gender role, and extraversion-introversion in the expression, experience and control of anger. A sample of 110 persons drawn from the Australian community were administered the Staxi-2, EPQ-R and the BSRI. Results showed that extraversion-introversion accounted for most variance associated with anger expression, while gender role accounted for most variance associated with anger control. Biological sex was not …
The Relationships Among Age, Physical Activity, And Working Memory, Ellen M. Carpenter
The Relationships Among Age, Physical Activity, And Working Memory, Ellen M. Carpenter
Psychology Theses & Dissertations
As our population ages, determining exogenous factors that may offset cognitive decline become increasingly important. The primary goal of the present study was to determine whether older individuals who engage in regular physical activity demonstrate superior working memory performance relative to older sedentary individuals. Forty young (20 active, 20 sedentary) and forty older (20 active, 20 sedentary) individuals engaged in cognitive measures of information processing speed, inhibitory function, and verbal and visuospatial working memory. Age differences in recall were found for verbal and visuospatial span tasks, as well as for recall reaction time on verbal and visuospatial n-back tasks, and …
