When Less Can Be More: Dual Task Effects In Stuttering And Fluent Adults, Naomi Nechama Eichorn

Dissertations, Theses, and Capstone Projects

The present study tested the counterintuitive hypothesis that engaging cognitive resources in a secondary task while speaking could benefit aspects of speech production. Effects of dual task conditions on speech fluency, rate, and error patterns were examined in stuttering and fluent speakers based on specific predictions derived from three related theoretical frameworks. Twenty fluent adults and 19 adults with confirmed diagnoses of stuttering participated in the study. All participants completed two baseline tasks: (1) a continuous speaking task in which spontaneous speech was produced in response to given prompts; and (2) a working memory (WM) task involving manipulations of WM …

A Derivation Of The Tonal Hierarchy From Basic Perceptual Processes, David Smey

Dissertations, Theses, and Capstone Projects

In recent decades music psychologists have explained the functioning of tonal music in terms of the tonal hierarchy, a stable schema of relative structural importance that helps us interpret the events in a passage of tonal music. This idea has been most influentially disseminated by Carol Krumhansl in her 1990 monograph Cognitive Foundations of Musical Pitch. Krumhansl hypothesized that this sense of the importance or centrality of certain tones of a key is learned through exposure to tonal music, in particular by learning the relative frequency of appearance of the various pitch classes in tonal passages. The correlation of pitch-class …

Executive Dysfunction And Reward Dysregulation: Interactions In Drug Addiction, Kristen Paula Morie

Dissertations, Theses, and Capstone Projects

Cocaine addiction is a serious public health hazard, and contributes to disastrous outcomes for individuals who suffer from it. Addiction is accompanied by an inability to control one's own behavior, and a preoccupation with cocaine at the expense of other rewarding pursuits. Previous research has suggested that difficulties with executive function and reward processing may underlie these problems, but the extent to which each contributes to addiction severity, or how these two factors may interact, remains to be elucidated. By using event related potential (ERP) measures in combination with information about self-reported anhedonia over three experiments, we set out to …

Factlessness & Faultlessness: Individual Differences & Dimensions Of Philosophical Dispute, Geoffrey Scott Holtzman

Dissertations, Theses, and Capstone Projects

This project addresses the question of why philosophical disputes persist, and tackles the problem of how we might better approach them. I demonstrate empirically several ways in which personality, gender, and other factors are associated with specific philosophical beliefs. Typically, one might assume that these individual difference factors are irrelevant to philosophy, and can only serve to bias philosophical disputants. Against this view, I present four case studies, which collectively highlight the different ways in which individual differences in lived experience may be inseparable from philosophical concepts themselves.

“Me & My Brain”: Exposing NeuroscienceʼS Closet Dualism, Liad Mudrik, Uri Maoz

Psychology Faculty Articles and Research

Our intuitive concept of the relations between brain and mind is increasingly challenged by the scientific world view. Yet, although few neuroscientists openly endorse Cartesian dualism, careful reading reveals dualistic intuitions in prominent neuroscientific texts. Here, we present the “double-subject fallacy”: treating the brain and the entire person as two independent subjects who can simultaneously occupy divergent psychological states and even have complex interactions with each other—as in “my brain knew before I did.” Although at first, such writing may appear like harmless, or even cute, shorthand, a closer look suggests that it can be seriously misleading. Surprisingly, this confused …

Influence Of Seductive Details, Belief-Congruence, And Repeated Testing On Memory For Controversial Information, Daniel Adam Nuccio

Theses and Dissertations

People often encounter conflicting information on a wide array of topics. How they evaluate this information in relation to their current beliefs, and the effects of other influences, such as the weight given to superficial aspects of the information (e.g. pictures, anecdotes, or jargon that are at most minimally related to an author's argument), has been of interest to researchers for many years. One component of their processing

and evaluation of this information is their memory for the information. This study set out to examine the following questions: (1) Is belief-congruent in

formation remembered better or worse than belief incongruent …

Effects Of Popular Music On Memorization Tasks, Kristin Sandberg, Sarah Harmon

Journal of Undergraduate Research at Minnesota State University, Mankato

This study investigated the effects that popular music has on memory performance. It was proposed that popular music would adversely affect both studying and memory recall. Forty introductory psychology students participated in the study. Subjects were given a list of fifty words to study in 6 ½ minutes, with music either being present or absent. This was termed the learning stage. In this study, four conditions were tested. In all 4 conditions, subjects were assigned to either a “music” pre-period or a “non-music” pre-period and a “music” post-period or a “non-music” post-period. After they had studied the words, subjects were …

Effects Of Race Of Attractiveness Ratings And Individuals Physical Attractiveness Stereotypes, Aaron Karst

Journal of Undergraduate Research at Minnesota State University, Mankato

The purpose of this research project was to investigate the “physical attractiveness stereotype”. Previous research suggests that the physical attractiveness plays an important role in how we ascribe certain personality traits. Weiten (2002) for example, noted the stereotype as people’s tendency “to ascribe socially desirable personality traits to individuals who are considered to be more attractive, seeing them as more sociable, poised, and well adjusted than those who are less attractive”. However, very little research has been conducted to explore the role race may have on the concept. The current study was conducted to explore the validity of the physical …

Distinguishing Observed Inattentive Behaviors In The College Classroom As They Correlate To Brain Wave Activity Utilizing A Wireless Electroencephalograph, Christopher J. Aura, Matthew R. Stanton

Journal of Undergraduate Research at Minnesota State University, Mankato

A significant amount of research has been devoted to the behavioral correlates of inattention in children (A.P.A., 2000; Arnold, 2000; Gordon & Barkley, 1998). It is proposed by the authors that college students, in their several years of experience, are much more capable of masking these trademark behaviors. When a child loses interest they will begin to openly look around the room, shift in their seat, or chat with their neighbors (Sandberg, Rutter & Taylor, 1978; Arnold, 2000). College students however, are proposed to candidly fidget, shift in their seat, or even maintain eye contact with their instructor while “daydreaming”. …

Sustained And Transient Reward Effect On Cognitive Control In Schizophrenia: The Relevance Of Negative Symptoms, Yu Sun Chung

All Theses and Dissertations (ETDs)

Schizophrenia (SCZ) is characterized by severe cognitive impairments and amotivation, generally referred to as negative symptoms, including anhedonia and/or avolition. Amotivation tends to exist in prodromal patients and persist over the illness course regardless of successful antipsychotic medications, which are known to reduce positive symptoms, including hallucination and delusions (e.g., (Horan, Blanchard, Clark, & Green, 2008; Tarbox et al., 2013). Importantly, amotivation is a promising predictor for later social functioning in SCZ, even after accounting for patients' cognitive impairments (e.g., (Evensen et al., 2012; Faerden et al., 2010). Despite this crucial impact on functioning outcome in SCZ, to date, no …

The Adversity Pop Culture Has Posed, Darel Joseph

LSU New Orleans Theses and Dissertations

I am a collage artist working with multiple mediums such as paint, photography, video, audio, and performance. As a New Orleans’ native, I have a unique history that is unflattering, for my history echoes that of America’s historical misdeeds. I make sociopolitical art because I am of a historically oppressed people. I make art that celebrates my diverse culture that is a collage of Native American, African, and New Orleans’ French Creole.

Short-Term Visual Deprivation, Tactile Acuity, And Haptic Solid Shape Discrimination, Charles E. Crabtree

Masters Theses & Specialist Projects

The visual cortex of human observers changes its functionality in response to visual deprivation (Boroojerdi et al., 2000). Behavioral studies have recently documented enhanced tactile abilities following a short period of visual deprivation (Facchini & Aglioti, 2003; Weisser, Stilla, Peltier, Hu, & Sathian, 2005). The current study investigated the effects of visual deprivation on two unique tactile tasks. While Facchini and Aglioti observed significant effects of visual deprivation, neither Wong, Hackeman, Hurd, and Goldreich (2011) nor Merabet et al. (2008) observed these effects. Corroborating these more recent results, no difference in grating orientation discrimination performance was observed between the sighted …

Explaining Implicit And Explicit Affective Linkages In It Teams: Facial Recognition, Emotional Intelligence, And Affective Tone, Mary M. Dunaway

Graduate Theses and Dissertations

Over 80 percent of task work in organizations is performed by teams. Most teams operate in a more fluid, dynamic, and complex environment than in the past. As a result, a growing body of research is beginning to focus on how teams’ emotional well-being can benefit the effectiveness of workplace team efforts. These teams are required to be adaptive, to operate in ill-structured environments, and to rely on technology more than ever before. However, teams have become so ubiquitous that many organizations and managers take them for granted and assume they will be effective and productive. Because of the increased …

Impaired Theory Of Mind In Psychotic And Affective Disorders, Erik Nelson Ringdahl

UNLV Theses, Dissertations, Professional Papers, and Capstones

Psychotic symptoms in bipolar I disorder during mood episodes has been associated with several negative outcomes raising the question as to whether psychosis is a risk factor for a more severe form of this chronic and debilitating condition. However, relatively little research has been directed at understanding the relationships among social cognitive functioning in bipolar I disorder with and without a history of psychosis. Impaired social cognition has been identified as a putative endophenotypic markers in schizophrenia and the evidence is mounting as to whether similar impairments also exist in bipolar I disorder. Given the plethora of research supporting the …

Dual Task Interference In Low-Level Abilities: The Role Of Working Memory And Effects Of Mathematics Anxiety, Alex Michael Moore

UNLV Theses, Dissertations, Professional Papers, and Capstones

Mathematics anxiety is a negative affective reaction to situations involving mathematical thought and is commonly believed to reduce cognitive functioning by impairing the efficient use of working memory resources. The conventional theory describes that the processing disadvantage associated with high levels of math anxiety increasingly impairs performance as working memory demands increase in a math task. Despite this convention, recent reports demonstrate that the high math anxious disadvantage can be measured in tasks that are relatively free of working memory assistance (Maloney, Ansari, & Fugelang, 2011; Maloney, Risko, Ansari, & Fugelsang, 2010). The present study examines these relatively low level …

The Effects Of Working Memory On Brain-Computer Interface Performance, Samantha A. Sprague

Electronic Theses and Dissertations

Amyotrophic lateral sclerosis and other neurodegenerative disorders can cause individuals to lose control of their muscles until they are unable to move or communicate. The development of brain-computer interface (BCI) technology has provided these individuals with an alternative method of communication that does not require muscle movement. Recent research has shown the impact psychological factors have on BCI performance and has highlighted the need for further research. Working memory is one psychological factor that could influence BCI performance. The purpose of the present study is to evaluate the relationship between working memory and brain-computer interface performance. The results indicate that …

Implicit Theories Of Intelligence And Learning A Novel Mathematics Task, Nathan Oehme Rudig

UNLV Theses, Dissertations, Professional Papers, and Capstones

The social-cognitive model of motivation states that students adopt a theory of the nature of intelligence that guides their goals in academia and their responses to academic setbacks. Students who believe intelligence is an unchanging entity within them are more likely to adopt goals to display high ability, hide low ability, and respond helplessly to failed schoolwork. Conversely, a student who believes intelligence is a measure of effort and persistence will be motivated to gather knowledge and acquire new skills. The current study investigated the role theories of intelligence play in the field of mathematics understanding. In two experiments, participants …

Looking At The Multiple Meanings Of Numeracy, Quantitative Literacy, And Quantitative Reasoning, H. L. Vacher

Numeracy

The subject of this journal goes by a variety of names: numeracy, quantitative literacy, and quantitative reasoning. Some authors use the terms interchangeably. Others see distinctions between them. Study of psycholinguistic and ontological concepts laid out in the literature of WordNet and familiarity with the papers in this journal suggests a vocabulary matrix consisting of four rows (word senses) and three columns (word forms, namely numeracy, QL, and QR). The four word senses correspond to four sets of synonyms: {numeracy}, {numeracy, QL}, {QL, QR}, and {numeracy, QL, QR}. Each of the word forms is polysemous: “numeracy” points to the first, …
