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 …

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. …

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 …

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 …

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 …

Task-Switching In Bilinguals: Further Investigation Of The Bilingual Advantage, Jennifer M. Brown

Theses and Dissertations

Recent research has suggested that speaking more than one language may lead to benefits across a variety of different cognitive tasks (Bialystok, Craik, Green, & Gollan, 2009). This effect has been dubbed the Bilingual Advantage. It has been suggested that this advantage relates to more the development of greater efficiency with processes involved in task-switching. The current study used a task-switching task to investigate three of these processes: reconfiguration, monitoring, and inhibitory control processes.

Monolingual and bilingual participants were presented blocks of trials in which they had to either categorize words as either abstract or concrete, or pictures as human-made …

Examining The Effect Of Education Type On Common Misconceptions Of Traumatic Brain Injury, Monica De Iorio

Seton Hall University Dissertations and Theses (ETDs)

It has been widely shown that misconceptions related to traumatic brain injury (TBI) are held among both family members of people with TBI and the general public. These misconceptions have the potential to increase the distress of people with TBI and negatively impact rehabilitation processes. Although increased education has often been suggested to reduce misconceptions, few studies have examined which methods are most effective in providing information to the public. In the current study, I investigated the effects of existing education materials – either a TBI factsheet or personal stories of people with TBI. These materials are currently easily accessible …

A Signal Detection Experiment With Limited Number Of Trials, Tadamasa Sawada

MODVIS Workshop

Signal detection theory has been well accepted in vision science to measure human sensitivity to stimuli in a Psychophysical experiment. The theory is formulated so that the measured sensitivity is independent from a response bias (criterion). The formulation is based on an assumption that number of trials in the experiment is infinite but this assumption cannot be satisfied in practice. The assumption came from two normal distributions used in the formulation. The distributions respectively represent a set of signal trial and that of noise trials in the experiment. In this study, I will show how the violation of the assumption …

Come Closer: Cognitive Dissonance Between Strangers, Melissa Bond, Connie Shears

Student Scholar Symposium Abstracts and Posters

Whether it’s reacting to unwanted invasion of our personal space (Khan & Kamal, 2010) or creating interpersonal warmth using physical touch (Williams & Bargh, 2008), our interactions with others affect us every day. But how will you feel toward a stranger that you voluntarily let invade your personal space? Cognitive dissonance states that our behaviors will dictate our attitudes instead of the other way around (Festinger, 1957) and is typically studied within an individual. The current study investigates cognitive dissonance between two people. To test the hypothesis that physical touch would change two strangers’ perception of “closeness,” we manipulated three …

Bayesian Modeling Of 3d Shape Inference From Line Drawings, Seha Kim, Jacob Feldman, Manish Singh

MODVIS Workshop

Human depth comparisons in line drawings reflect the underlying uncertainty of perceived 3D shape. We propose a Bayesian model that estimates the 3D shape from line drawings based on the local and non-local contour cues. This model estimates the posterior distribution over depth differences at two points on a line drawing. The likelihood is numerically computed by assuming a generative model, which generates random 3D surfaces and, via projection, random line drawings. The 3D surfaces are inflated from random skeletons and projected into line drawings. Given a novel line drawing, the model samples probable local surfaces based on the relations …

Intuitive Thought And Consumer Decision Making, Morgan M. Moore

Senior Honors Projects, 2010-2019

Anytime the human mind makes a decision, intuitive thought has played a hidden role. There is more to consumer decision making than just logical, slow cognition. Exploring the intuitive mind through the works of Johnathan Haidt and Daniel Kahneman helps researchers understand the roles and origins of intuition. Proof of the presence and power of intuitive thought in cognitive processes is offered. A subset of the intuitive mind, termed the righteous mind by Haidt, is shown to be responsible for moral intuition. As the role of intuitive thought in consumer decision making is considered, numerous marketing applications are applied. Whether …
