Retroactive Interference In Recognition Memory: The Effects Of Mental Effort And Similarity On Recollection And Familiarity, Caleb Jordan Picker

UNLV Theses, Dissertations, Professional Papers, and Capstones

Learning new material may retroactively interfere with memory for older material. Retroactive interference research has typically focused on how similarity between old and new material affects recall of old material, which predicts greatest interference when similar material is presented just before test. However, mental effort may be another source of retroactive interference that could disrupt consolidation: Mental effort could cause the most retroactive interference when presented just after study. In Experiment 1, participants engaged in tasks designed to induce mental effort (e.g., solving easy or difficult math problems) at various times between the study and test of an associative recognition …

The Effect Of Sleep On Perceptual Learning And Memory Consolidation, Vanessa Claire Irsik

UNLV Theses, Dissertations, Professional Papers, and Capstones

An ability to segregate speech accurately is essential given that most auditory environments contain other overlapping conversations or environmental noise. While perceiving speech among background noise can be difficult in and of itself, those with hearing impairments can experience considerable difficulty. While training has been shown to benefit perceptual segregation of trained sounds, it is unclear how such training transfers to sounds not included in a training regimen. The current study aimed to address this question by training listeners on a portion of sounds during a vowel segregation task, and subsequently testing on both the trained sounds and untrained sounds. …

Variability In Depressive Symptoms Of Cognitive Deficit And Cognitive Bias During The First 2 Years After Diagnosis In Australian Men With Prostate Cancer, Christopher Sharpley, Vicki Bitsika, David Christie

Vicki Bitsika

The incidence and contribution to total depression of the depressive symptoms of cognitive deficit and cognitive bias in prostate cancer (PCa) patients were compared from cohorts sampled during the first 2 years after diagnosis. Survey data were collected from 394 patients with PCa, including background information, treatments, and disease status, plus total scores of depression and scores for subscales of the depressive symptoms of cognitive bias and cognitive deficit via the Zung Self-Rating Depression Scale. The sample was divided into eight 3-monthly time-since-diagnosis cohorts and according to depression severity. Mean scores for the depressive symptoms of cognitive deficit were significantly …

Impaired Executive Function In Concussed Athletes, Marisa Gretz

Neuroscience Summer Fellows

Concussions are classified as mild traumatic brain injuries (mTBI). An individual that has sustained a concussion will experience symptoms such as nausea, possible memory loss, blurry vision, or loss of balance. Most symptoms subside within a few days, but a large pool of research raises concern for the recovery of executive function, specifically impulse control. Executive function relates to all tasks that require deliberate attention. Past research has shown adolescents record the highest number of sports concussions when compared to collegiate and professional athletes. The frontal lobe, which controls executive function, is not fully developed during the time of adolescence. …

Event-Related Potential Markers Of Perceptual And Conceptual Speech Processes In Patients With Disorders Of Consciousness., Stephen T. Beukema

Electronic Thesis and Dissertation Repository

Vegetative state (VS) and minimally conscious state (MCS) patients behaviorally demonstrate absent or fluctuating levels of awareness. Functional magnetic resonance imaging evidence of covert perceptual and semantic speech processing provides prognostic value for these patients. In this thesis, I examined the utility of high-density electroencephalography (EEG) in this regard. A contrast between event-related potentials (ERPs) elicited by primed and unprimed word pairs was used to isolate conceptual (semantic) processes, while ERPs elicited by signal-correlated noise were contrasted with those elicited by speech to isolate pre-semantic, perceptual aspects of speech processing. These ERP effects were found to be both temporally and …

The Relationship Between Arousal, Personality, And Perception Of Control In A Gambling Task, Guillaume J. Pagnier

Masters Theses

The somatic marker hypothesis posits that physiological arousal is partially responsible for decision-making behavior. Arousal, measured by skin conductance responses (SCR), increases before deck choice in the Iowa Gambling Task (IGT). These markers co-vary with performance -- pathological gamblers lack these markers and perform poorly. Personality also modulates IGT behavior – high-novelty-seeking (NS) individuals tend to perform worse. In the IGT, participants decide which deck to select, creating a potential confound between personality, performance, and arousal. For example, high-NS individuals select the bad decks more often, potentially causing habituation and a muted SCR. The first goal of this research was …

Medicalization Of Depression, Anxiety, Schizophrenia, Adhd, Childhood Bipolar Disorder And Tantrums: Scientific Breakthrough, Or Broad-Based Delusion?, W. Wyatt

W. Joseph Wyatt

Clearly, a number of psychological and behavioral disorders arise within our biology. These include autism, Down’s syndrome, those due to toxin exposure, metabolic and endocrine difficulties, and several others. In contrast, there is minimal research evidence to support biological origins of the vast number of common disorders such as depression, anxiety disorders, schizophrenia or child problems such as conduct disorders, attention deficit hyperactivity disorder (ADHD), childhood bipolar disorder, oppositional behaviors or tantrums. These disorders have been medicalized when, in the absence of supportive research evidence, they are said to be caused by genetic defects, chemical imbalances or other biological phenomena. …

Assessment Of Validity And Response Bias In Neuropsychiatric Evaluations, Dustin Wygant, Robert Phillip Granacher

Psychology Faculty and Staff Research

BACKGROUND: Forensic neuropsychiatric assessment requires thorough consideration of malingering and response bias. Neuropsychiatric evaluations are complicated due to the multiple domains in which symptoms and impairment present. Moreover, symptom exaggeration in these evaluations can also present along various symptom domains (e.g., psychological, neurocognitive, somatic). Consequently, steps must be taken to ensure adequate coverage of response bias across all three domains of function.

PURPOSE: The following article reviews the conceptualization of malingering in neuropsychiatric settings, as well as various approaches and measures that can be helpful in the assessment of malingering and response bias.

CONCLUSIONS: Forensic neuropsychiatric assessment requires thorough consideration …

Explicit And Inferred Motives For Nonsuicidal Self-Injurious Acts And Urges In Borderline And Avoidant Personality Disorders, Avigal Snir, Eshkol Rafaeli, Reuma Gadassi, Kathy R. Berenson, Geraldine Downey

Psychology Faculty Publications

Nonsuicidal self-injury (NSSI) is a perplexing phenomenon that may have differing motives. The present study used experience sampling methods (ESM) which inquired explicitly about the motives for NSSI, but also enabled a temporal examination of the antecedents/consequences of NSSI; these allow us to infer other motives which were not explicitly endorsed. Adults (n = 152, aged 18–65) with borderline personality disorder (BPD), avoidant personality disorder (APD), or no psychopathology participated in a 3-week computerized diary study. We examined 5 classes of explicit motives for engaging in NSSI, finding support primarily for internally directed rather than interpersonally directed ones. We then …

Examining Possible Perceptual Proxies Of Flow State, Devin Michael Gill

Theses and Dissertations

Nakamura and Csikszentmihalyi (2002) define flow as an individual's deep engagement in an intrinsically rewarding activity. McGonigal (2011) suggests that video games are flow elicitors. If video games are flow elicitors, then spatial, agentic, and temporal perception required for game play may relate to flow in predictable manners. Over two experiments, a simple video game with contextual (i.e., implied friction) and conceptual (i.e., ambiguous stimulus labeled either bullet-train or house) manipulations was used to elicit flow. Effects of the manipulations were assessed trial-by-trial on two dimensions of flow (i.e., agency and temporal perception) and spatial planning, as well as an …

The Effects Of Alcohol On The Interpretation Of Social And Emotional Cues: A Field Study Of College Student Drinking, Emotion Recognition, And Perceptions Of A Hypothetical Sexual Assault, Alexander James Melkonian

Graduate Theses and Dissertations

Alcohol use and abuse among emerging adults is highly correlated with increased risk for sexual victimization. Alcohol myopia theory has been used to explain impairments in Social information processing resulting in decreased attention to environmental Social cues including risk factors for sexual assault as well as facial emotional recognition. Those with deficits in Social information processing may be at particular risk for the misperception of salient risk factors for sexual assault by victims, perpetrators, and bystanders when intoxicated. In this naturalistic field study, participants who had been consuming alcohol were recruited to engage in tasks of facial emotion recognition and …

Executive Function Predictors Of Children's Talk, Jacqlyne D. Weber

Undergraduate Honors Theses

Relatively few studies have investigated the relationship between executive functioning (EF) and language development, and even fewer have researched hot and cool EF as a predictor language development. This study is an investigation into the relationship between EF and language development in preschool aged children. More specifically, the ability for hot or cool EF to predict language, this will be the focus of the study. It was found that hot EF was a better predictor of language development in preschool aged children.

Cognitive Features Of Self-Stigmatization Among Juvenile Delinquents, Artyom A. Zinchenko, Mamun Al-Amin, Elena Molchanova

Journal of Health Disparities Research and Practice

The present study investigates cognitive features of stigmatization phenomenon among juvenile delinquents in Kyrgyzstan. It attempts to describe certain peculiarities of juvenile delinquents’ self-schemas and self-stigmatization. The study, additionally, tackles the issue of currently existing stigmas regarding juvenile delinquency in the country. One hundred and fifty four university students were asked to complete a questionnaire that would measure the level of external stigmatization towards juvenile delinquents and those who were once placed into correctional institution. Students showed presence of stigmatization towards people with a criminal record. Fifteen juveniles from the detention school who attended a socio-psychological training as well as …

It Must Have Been Him: Coherence Effects Within The Legal System, Jonathan N. Carbone

FIU Electronic Theses and Dissertations

The present series of studies examine how jurors and public defenders evaluate different pieces of evidence and integrate them into a coherent conclusion within the context of a criminal case. Previous research has shown that in situations where both sides of the case are compelling, decision-makers nevertheless come to highly confident and polarized decisions, called coherence shifts (Simon, 2004). The present research sought to expand on coherence effects, improve upon the methodology of previous studies, and explore potential moderators of coherence. In Study 1, mock jurors (n = 306) read about a criminal case and evaluated multiple pieces of …

The Effects Of Post-Recall Feedback: Examining Witness Recall Quantity, Accuracy, And Confidence, Dana Elizabeth Hirn Mueller

FIU Electronic Theses and Dissertations

Most eyewitness identification protocols recommend withholding feedback after an identification has been made, at least until a measure of confidence can be gathered. Although much research has examined the impact of post-identification feedback on subsequent witness behavior and confidence, research addressing the importance of post-recall feedback remains largely incomplete. The current study examined the effects of post-recall feedback and question type on subsequent witness recall, confidence, and reports of view of the crime. In line with previous eyewitness identification research, it was predicted that participants receiving confirming post-recall feedback would be more confident in their prior recall compared to participants …

Blood Alcohol Concentration Is Negatively Associated With Gambling Money Won On The Iowa Gambling Task In Naturalistic Settings After Controlling For Trait Impulsivity And Alcohol Tolerance, Michael Lyvers, Nicole Mathieson, Mark Edwards

Mark Edwards

Introduction: Acute alcohol intoxication has been found to increase perseverative errors on the Wisconsin Card Sorting Test, a well known neuropsychological index of prefrontal cortical functioning, in both laboratory and naturalistic settings. Method: The present study examined the relationship between levels of alcohol consumption at campus drinking venues and performance of the Iowa Gambling Task (IGT), another neuropsychological test designed to assess prefrontal cortex dysfunction, after controlling for potential confounding variables including habitual alcohol intake (as a proxy for alcohol tolerance), trait impulsivity, and everyday executive functioning. Results: The 49 participants of both genders aged 18 to 30 years were …

Developing & Describing The Use & Learning Of Conceptual Models For Integer Addition And Subtraction Of Grade 5 Students, Nicole Marie Wessman-Enzinger

Theses and Dissertations

This dissertation reports the results of a teaching experiment, which explored student thinking about integer addition and subtraction. Through the lens of commognitive theory (Sfard, 2008), interpreting negative integers as secondary intuitions (Fischbein, 1987), and employing teaching experiment methodology (Steffe & Thompson, 2000), this study was a first step in developing more robust descriptions of students' conceptual models for integer addition and subtraction. I investigated: (a) the conceptual models that students exhibited, (b) the various ways that students utilized conceptual models while learning about the addition and subtraction of integers, and (c), the ways that students' conceptions evolved over the …

Mathematical Models Of Games Of Chance: Epistemological Taxonomy And Potential In Problem-Gambling Research, Catalin Barboianu

UNLV Gaming Research & Review Journal

Games of chance are developed in their physical consumer-ready form on the basis of mathematical models, which stand as the premises of their existence and represent their physical processes. There is a prevalence of statistical and probabilistic models in the interest of all parties involved in the study of gambling – researchers, game producers and operators, and players – while functional models are of interest more to math-inclined players than problem-gambling researchers. In this paper I present a structural analysis of the knowledge attached to mathematical models of games of chance and the act of mathematical modeling, arguing that such …

Challenges To Audit Education For The 21st Century: A Survey Of Curricula, Course Content, And Delivery Methods, Christine Earley, Eric Johnson, Jane Baird, Paul Caster, William Dilla, Timothy Louwers

Eric N. Johnson

This paper reports the results of a survey of auditing and assurance courses in the US and several other countries conducted during 2000-2001. The survey, commissioned by the Auditing Section of the American Accounting Association, yielded data on a total of 285 auditing and assurance courses taught at 188 colleges and universities in the United States, Canada, and several other countries. The syllabi data were analyzed on a number of dimensions and the results compared to two prior surveys of auditing courses (Frakes, 1987; Groomer and Heintz 1994). Our findings document substantial changes in content (e.g., new or expanded coverage …

The Divergent Effects Of Fear And Disgust On Inhibitory Control: An Erp Study., Mengsi Xu, Zhiai Li, Cody Ding, Junhua Zhang, Lingxia Fan, Liuting Diao, Dong Yang

Education Sciences and Professional Programs Faculty Works

Negative emotional stimuli have been shown to attract attention and impair executive control. However, two different types of unpleasant stimuli, fearful and disgusting, are often inappropriately treated as a single category in the literature on inhibitory control. Therefore, the present study aimed to investigate the divergent effects of fearful and disgusting distracters on inhibitory control (both conscious and unconscious inhibition). Specifically, participants were engaged in a masked Go/No-Go task superimposed on fearful, disgusting, or neutral emotional contexts, while event-related potentials were measured concurrently. The results showed that for both conscious and unconscious conditions, disgusting stimuli elicited a larger P2 than …

A Spelling Pronunciation Strategy Helps College Students Remember How To Spell Difficult Words, Turkan Ocal

Dissertations, Theses, and Capstone Projects

Drake and Ehri (1984) showed that children could utilize a spelling pronunciation strategy in order to remember spellings of words. One purpose of the current study was to determine whether college students could also benefit from a spelling pronunciation strategy in remembering spellings of 20 commonly misspelled words. The second aim of the study was to examine the contribution of decoding skill, exposure to print and vocabulary knowledge in explaining variance in general spelling ability of college students. Based on Share's (1995) self-teaching hypothesis, each of these predictors was expected to explain unique variance in the ability to remember the …

Generalized Event Representation In Pre-School Children With Mild- To High-Functioning Autism Spectrum Disorder (Asd) And Children With Cognitive And Linguistic Delays (Cld), Tashana S. Samuel

Dissertations, Theses, and Capstone Projects

Children with autism spectrum disorder (ASD) frequently establish rigid routines and have difficulties flexibly applying what they have learned. Three experiments were conducted to examine generalized event representation in 34 pre-school children. In Experiment 1, children diagnosed with varying kinds of cognitive and language delays (CLD: n = 14) were tested with the generalized imitation paradigm, a reliable measure of representational capacity. Two sets of perceptually dissimilar objects with similar functions were used to perform the same task: one set consisted of modeling props and the other set was the generalization props. At the generalization assessment, children observed actions modeled …

Women: The Ignored Majority, Carol T. Mowbray, Daphna Oyserman, Catherine J. Lutz, Rogeair Purnell

Catherine Lutz Zois

The major thrust of psychiatric rehabilitation is to provide skill development and supports enabling individuals to function in their roles of choice. The model thus contains an underlying assumption that meaningful life roles are “chosen” roles. It therefore may tend to overlook the impact on persons’ lives of the roles that they are given. These given or ascribed roles include those based on gender, ethnicity, and socioeconomic class. Self-definitions, behaviors, beliefs, attitudes, and values are all likely to be structured within such social roles, which can also serve as important social identities (Oyserman & Markus, 1993). In spite of increased …

Explaining The Link Between Perfectionism And Self-Forgiveness: The Mediating Roles Of Self-Acceptance And Rumination, Lee Dixon, Katherine Earl, Catherine Lutz-Zois, Jackson Goodnight, Jessica Peatee

Catherine Lutz Zois

Although recent research has begun to examine correlates of self-forgiveness, very little research has examined the association between self-forgiveness and perfectionism. This study examined this association, along with mediating mechanisms that help explain this association. Specifically, we examined the indirect relationships between both Conscientious and Self-Evaluative forms of perfectionism and episodic self-forgiveness, through both unconditional self-acceptance and rumination. Participants (N = 206) completed measures of perfectionism, unconditional self-acceptance, rumination about a specific betrayal they committed, and self-forgiveness of said betrayal. Multivariate path analyses revealed Self-Evaluative Perfectionism to be indirectly associated with self-forgiveness, through both unconditional self-acceptance and rumination. More specifically, …

Perceived Similarity And Relationship Success Among Dating Couples: An Idiographic Approach, Catherine Lutz, Angela Bradley, Jennifer Mihalik, Erika Moorman

Catherine Lutz Zois

This study utilized an idiographic approach to investigate the relation between similarity on valued characteristics and relationship success. College students (N = 247) rated their current romantic partner on perceived similarity in personality, attitudes, interests, and religious affiliation; the importance of similarity in these dimensions; and relationship satisfaction. Relationship status was assessed 6 weeks later. Results revealed significant similarity by importance interactions for religion and interests in predicting satisfaction. Participants with high perceived similarity in religion or interests reported greater satisfaction than did their low similarity counterparts, but only to the extent that they rated this type of similarity as …
