Improving Memory Using N-Back Training, Paul Beavon

Theses : Honours

Investigations into n-back training and near transfer to short-term memory (STM) and working memory (WM) have realised inconsistent results. A significant transfer to STM was reported using dual n-back training (Jaeggi, Buschkuehl, Jonides, & Perrig, 2008). However, the majority of studies have found no significant transfer to WM as operationalised by complex span tasks using either single or dual n-back training. The current study examined the single n-back task and near transfer to STM and WM as operationalised by the Woodcock-Johnson III Tests of Cognitive Abilities (Mather & Woodcock-Johnson, 2001). Forty-seven participants were divided into experimental treatment (n = 26) …

The Effect Of Musical Training On Verbal And Tonal Working Memory, Ching-I Lu

Wayne State University Dissertations

This dissertation explored the translation from print to sound of the tonal language Mandarin versus English versus musical notation in healthy volunteers. The performance of musicians and non-musicians was compared across a variety of reading tasks in an attempt to examine whether musical training can facilitate Mandarin tone or phonological processing. The effects of increasing working memory load on reading performance across tasks were also examined. Results showed that increasing demands on working memory in visual recognition tasks significantly decreased performance accuracy for both musicians and non-musicians across tasks. Significant differences in accuracy rates were observed between musicians and non-musicians. …

Does Need For Cognition Moderate The Relationship Between Eyewitness Age And Perceived Credibility?, Anna E. Pittman

UNF Graduate Theses and Dissertations

The relationship between age and perceived credibility was examined, particularly whether or not middle-aged witnesses were perceived as more credible than older eyewitnesses. Additionally, I was interested in whether or not the relationship between age and credibility was moderated by need for cognition. Participants read a trial transcript about a child pedestrian-car accident wherein a defendant was charged with manslaughter. The sole eyewitness, either a 49 or 79 year-old male, testified that the child hit his head on a rock upon stepping off the curb before being struck by the defendant’s vehicle. Transcripts included direct and cross-examination with half accompanied …

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 …

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 …

Implicit Attitudes Of Ethnicity And Language: Evaluative And Associative Priming, Eva Margarita De La Riva Lopez

Open Access Theses & Dissertations

Most members of minority groups belong to both an ethnic and a linguistic minority. The interplay between these two related yet independent constructs has not been explored. For this reason, this study examined language attitudes following the theoretical model of social categorization by using implicit measures. This study also investigated the implicit association between language and ethnicity. In this manner, the relationship that exists between attitudes towards minority groups and attitudes towards minority languages can be disentangled. A simultaneous study of implicit attitudes of ethnicity and language, and the association between ethnicity and language, may elucidate possible mechanisms involved in …

Adding Within-Utterance Emotion Decay For More Human-Like Dialog, Michael Hans Durcholz

Open Access Theses & Dissertations

While spoken dialog systems have been used for commercial applications for several decades, most commercial spoken dialog systems provide only simple information exchange capabilities. Emotion synthesis in spoken dialog systems has become an active research area recently, and use of emotion-adaptive dialog systems has demonstrated improvements in user experience and rapport. This thesis seeks to improve how emotions are conveyed in dialog systems to enable robust emotional support that improves user experiences with dialog systems and models human speech characteristics more accurately than current dialog systems.

Prior work with Gracie (GRAduate Coordinator with Immediate response Emotions), an emotion-adaptive dialog system, …

The Wounded Healer: Finding Meaning In Suffering, Garret B. Wyner

Antioch University Dissertations & Theses

In modern history, no event has more profoundly symbolized suffering than the Holocaust. This novel “Husserlian-realist” phenomenological dissertation elucidates the meaning of existential trauma through an interdisciplinary and psychologically integrative vantage point. I use the testimony of a select group of Holocaust witnesses who committed suicide decades after that event as a lens to examine what their despair may reveal about an unprecedented existential, moral, and spiritual crisis of humanity that threatens to undermine our faith in human history and reality itself. By distinguishing what they actually saw about our condition from what they merely believed about reality, I show …

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 …

Abused Women Who Kill: Juror Perspectives On Self-Defense Theories, Shahrzad Nikoo

CMC Senior Theses

In self-defense cases of battered women who kill their abusive husbands, defendants have used Battered Woman Syndrome (BWS) expert testimony to help justify their acts of self-defense. However, past research demonstrates that BWS is ineffective in persuading jurors because it pathologizes the defendant rather than rationalizing her behavior. Additionally, BWS highlights passive (i.e., stereotypical) features of a battered woman, and such testimony may not apply to a defendant with active (i.e., atypical) features of a battered women. The current study hypothesized that another type of expert testimony, Social-Agency Framework (SAF), will persuade jurors to render more lenient verdicts, and that …

"...Bless Her Little Heart!": The Culture Of Honor And Emotion Recognition, Forrest J. Rackham

College of Graduate Studies: Theses & Dissertations

Author's abstract: Some researchers assert that cultural display rules may explain differences in perceiving emotions (Matsumoto, Yoo, & Chung, 2010). The current study examined the display rule of masking within the Southern culture of honor. It was hypothesized that masking within the culture of honor negatively affects emotion perception sensitivity, particularly in the speed and accuracy of recognizing anger. Southern undergraduate students were primed with the culture of honor and then presented with the Emotional Expression Multimorph Task. Participants chose one of the six emotions (i.e., sad, happy, surprise, fear, disgust, or anger). It was hypothesized participants in the masking …

Self-Efficacy, Intrinsic Motivation, And Academic Outcomes Among Latino Middle School Students Participating In An After-School Program, Kate Niehaus, Kathleen Moritz Rudasill, Jill L. Adelson

Department of Educational Psychology: Faculty Publications

This longitudinal study examined how academic self-efficacy, intrinsic motivation, and participation in an after-school program contributed to the academic achievement of Latino middle school students over the course of one school year. Participants were 47 Latino students in sixth through eighth grades who attended two public middle schools in which an after-school program was held that was specifically for Latino students. Results from ordinary least squares regression revealed that intrinsic motivation was positively associated with students GPAs, self-efficacy was a positive predictor of students’ school attendance and standardized math achievement scores, and attendance at the after-school program also contributed positively …

Neonatal White Matter Abnormalities An Important Predictor Of Neurocognitive Outcome For Very Preterm Children, Lianne J. Woodward, Caron A. C. Clark, Samudragupta Bora, Terrie E. Inder

Department of Educational Psychology: Faculty Publications

Background: Cerebral white matter abnormalities on term MRI are a strong predictor of motor disability in children born very preterm. However, their contribution to cognitive impairment is less certain. Objective: Examine relationships between the presence and severity of cerebral white matter abnormalities on neonatal MRI and a range of neurocognitive outcomes assessed at ages 4 and 6 years. Design/Methods: The study sample consisted of a regionally representative cohort of 104 very preterm (≤32 weeks gestation) infants born from 1998–2000 and a comparison group of 107 full-term infants. At term equivalent, all preterm infants underwent a structural MRI scan that was …

Book Review: The Morality Of Social Identity, David Moshman

Department of Educational Psychology: Faculty Publications

Morality tells us how to treat each other. Social identity connects us to each other. But all is not well. Social identity connects us to a group and thus to its members. Morality requires justice for everyone, regardless of group. Thus considerations of morality and social identity often pull in different directions (Appiah, 2005; Moshman, 2007; Sen, 2006).

Two excellent and complementary new books, Children and Social Exclusion and Narrative and the Politics of Identity, address the developmental roots and implications of these issues. The first reviews and integrates multiple programs of research on children’s developing judgments about dilemmas …

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 …

The Relationship Between Positive Beliefs About Post-Event Processing And Social Phobia Symptoms, Amanda N. Hammond

UNF Graduate Theses and Dissertations

Meta-cognitive models have been utilized to explore the relations between worry and generalized anxiety disorder, as well as, the associations between rumination and depression. However, relatively few studies have focused on the role of meta-cognitive variables and social phobia symptoms. It is possible that individuals with social phobia follow a pattern of thinking similar to that of those who experience depressive rumination and worry. Specifically, it may be that individuals with social phobia hold positive beliefs about their highly negative prolonged post-event evaluations of social interactions. The primary goal of this study was the development and assessment of the Positive …

Calibration Research: Where Do We Go From Here?, Linda Bol, Douglas J. Hacker

Educational Leadership & Workforce Development Faculty Publications

Research on calibration remains a popular line of inquiry. Calibration is the degree of fit between a person's judgment of performance and his or her actual performance. Given the continued interest in this topic, the questions posed in this article are fruitful directions to pursue to help address gaps in calibration research. In this article, we have identified six research directions that if productively pursued, could greatly expand our knowledge of calibration. The six research directions are: (a) what are the effects of varying the anchoring mechanisms from which calibration judgments are made, (b) how does calibration accuracy differ as …

From Nixon’S War On Drugs To Obama’S Drug Policies Today: Presidential Progress In Addressing Racial Injustices And Disparities, Cigdem Sirin

Selected Works Temporary Series

This study investigates presidential progress in addressing racial injustices and disparities within the context of the war on drugs. I argue that racial inequalities emanating from the war on drugs have been largely overlooked and at times aggravated by previous administrations. Although there have been some improvements in this regard since President Obama took office, more extensive policy reforms are needed to better remedy such inequalities. I also argue that the viability of a progressive presidency for racial justice vis-à-vis U.S. drug policies depends not only on the personal agenda of the president but also on a supportive public as …

Age Differences In Revision Of Causal Belief, Kristi M. Simmons

Masters Theses & Specialist Projects

Inductive reasoning (IR) requires efficient working memory (WM). Research shows that the prefrontal cortex (PFC) is involved during WM tasks and that PFC functioning declines with age. The ability to comprehend and update text-based information requires an intact PFC and efficient WM and IR. The current study presented a series of messages about the investigation of a warehouse fire to 48 young and 48 older adults. One message contained a piece of misinformation which another message corrected later. It was hypothesized that a memory cue to the misinformation with the correction statement should benefit older adults the most during the …
