Electrophysiological Correlates Of Visual Object Category Formation In A Prototype-Distortion Task, Stephanie Marie Long

Graduate Theses and Dissertations

In perceptual learning studies, participants engage in extensive training in the discrimination of visual stimuli in order to modulate perceptual performance. Much of the literature in perceptual learning has looked at the induction of the reorganization of low-level representations in V1. However, much remains to be understood about the mechanisms behind how the adult brain (an expert in visual object categorization) extracts high-level visual objects from the environment and categorically represents them in the cortical visual hierarchy. Here, I used event-related potentials (ERPs) to investigate the neural mechanisms involved in object representation formation during a hybrid visual search and prototype …

Music, Language, And Rhythmic Timing, Rhimmon Simchy-Gross

Graduate Theses and Dissertations

Neural, perceptual, and cognitive oscillations synchronize with rhythmic events in both speech (Luo & Poeppel, 2007) and music (Snyder & Large, 2005). This synchronization decreases perceptual thresholds to temporally predictable events (Lawrance et al., 2014), improves task performance (Ellis & Jones, 2010), and enables speech intelligibility (Peelle & Davis, 2012). Despite implications of music-language transfer effects for improving language outcomes (Gordon et al., 2015), proposals that shared neural and cognitive resources underlie music and speech rhythm perception (e.g., Tierney & Kraus, 2014) are not yet substantiated. The present research aimed to explore this potential overlap by testing whether music-induced oscillations …

Effects Of Critical Reflection On University Students’ Cognitive Achievement In Agricultural Mechanization, Patterson P. Hilaire

Graduate Theses and Dissertations

Experiential learning continues to play a vital role in agricultural education and mechanization laboratories (Shoulders & Myers, 2013). An essential component of experiential learning is critical reflection. Critical reflection helps students process and construct meaning from laboratory experiences. A study conducted by Shoulders and Myers (2013) revealed that only 15.4% of the agricultural educators the researchers interviewed incorporated reflective practices laboratory experiences. The purpose of this study was to evaluate the effect of critical reflection on students’ achievement following five agricultural mechanization laboratory activities. The results from this study revealed that critical reflection had a consistently positive effect on immediate …

Values Vs. Self-Interest As Determinants Of Attitudes: Through A Construal Level Theory Lens, (Sometimes) Self-Interest Wins, Austin D. Eubanks

Graduate Theses and Dissertations

The present study (n = 335) attempted to conceptually replicate Hunt, Kim, Borgida, and Chaiken (2010) with a high-powered design to investigate whether values and self-interest differentially impact attitudes depending on psychological distance. Participants were assigned to complete a task that made self- or other-focused values more accessible, then indicated their attitudes about a student fee increase at a university to fund scholarships the participants would not be eligible to receive (thus going against their own financial self-interest for the well being of someone else). The memo describing the fee increase was manipulated such that the increase would be occurring …

The Role Of Dialect Words In Children’S Social Decisions, Madison Rose Myers-Burg

Graduate Theses and Dissertations

Recent research suggests that young children are capable of distinguishing between phonetically dissimilar spoken accents, yet have difficulty distinguishing between phonetically similar accents (Wagner, Clopper, & Pate, 2013). The present study aimed to determine whether the presence of dialect-specific vocabulary enhances young children’s ability to categorize speakers. Participants completed four training trials in which they were familiarized with photos of two children: one of whom used American English labels for test objects and one of whom used British English labels. After training trials, participants completed eight test trials in which they were asked to infer which target child would use …

Long-Term Focus Of Attentional Biases, Garrett Pollert

Graduate Theses and Dissertations

Prior research regarding attentional biases, or patterns of visual attention, have focused on attention over the initial second when exposed to pictoral food stimuli. This manuscript reviews the literature regarding attentional biases in overweight/obese individuals over this timeframe for the two previously defined components of attentional bias (attentional orientation and attentional maintenance). A new component is proposed, called “attentional re-engagement,” defined as the pattern of attentional shifts towards target stimulus types over longer periods of time. Overweight/Obese and Normal-weighted participants were recruited and engaged in an Extended Dot Probe task, wherein attentional orientation, maintenance, and re-engagement were assessed using the …

People Change: Impression Management Influences Autobiographical Memories, Holly Elizabeth Cole

Graduate Theses and Dissertations

This paper presents the results of an experiment that tested a new impression management strategy, termed memory enhancement, and the long-term implications of using memory enhancement. People often share the events that occur in their everyday lives to others in the form of stories. This research was designed to determine if people will alter the way they share previous events to create a specific impression. It is possible that using the impression management strategy of memory enhancement will create long lasting changes to the actual memory of the event. This was tested in an experiment in which participants were put …

From Foster Care To College: Student Stories Of Success, Tory Nicole England

Graduate Theses and Dissertations

The purpose of this qualitative study was to understand the different factors that empower young adults that were in foster care to be successful in a college environment. It has been documented that foster youth have significant challenges during secondary education (Conger & Rebeck, 2001; Geenen & Powers, 2006). Due to these challenges, foster youth attend and graduate higher education at a lower rate than their peers. The perspectives of foster youth currently enrolled in higher education is critical to determining which factors and programs have helped with their educational success. Five participants completed semi-structured interviews about their secondary education, …

The Role Of Attention And Memory In Prospective Person Memory, Kara Nicole Moore

Graduate Theses and Dissertations

I examined the role of memory and attention in prospective person memory. Prospective person memory involves being on the lookout for a person with the goal of completing some task (i.e., contacting the authorities) upon encountering the person. Success at prospective person memory tasks in lab and field based studies is rather low (i.e., less than 10% of people report encountering the person). In the current study the prospective person memory task involved a simulated search for a missing person. I manipulated attention to the missing person and strategic monitoring, which involves being in retrieval mode and searching for cues. …

Fitting Eyewitness Identification And Confidence To A Diffusion Model Of Processing, Brittany Nicole Race

Graduate Theses and Dissertations

It is necessary to better serve justice to understand the mechanisms behind eyewitness identification and reports of confidence. The material contained within attempt to fit eyewitness identification to a diffusion model of processing, RTCON (Ratcliff & Starns, 2009). Participants saw eight mock crime videos and were then tasked with using eight showups or eight lineups to identify the suspects within the video. Half of the presentations were target present and half were target absent. Additionally, participants were either presented with biased or unbiased instructions. Strangely, unbiased lineups led to higher hit rates which is contrary to most findings in the …

Recognition Training For Faces Across Age Gaps, William Blake Erickson

Graduate Theses and Dissertations

Face recognition is a problem that has theoretical and applied value. However, the fact of facial aging is rarely addressed in research and unmentioned in the major theories of face recognition. Facial aging also has ramifications for missing persons and fugitive cases, confounding attempts by law enforcement to recover these people whose last known images are years or decades out of date. This dissertation reports three studies aimed at measuring baseline age-gap recognition ability and testing various training regimens designed to increase accuracy rates for this unique kind of recognition task.

Familiarity Bias: Examining A Cognitive-Affective Mechanism Underlying Ideological Support For The Status Quo, John C. Blanchar

Graduate Theses and Dissertations

It is well established that people like familiarity over novelty. Because that which is most familiar is frequently indicative of the way things are, favoring familiarity should create a psychological advantage for the status quo. In two studies, I tested the hypothesis that familiarity bias—susceptibility to the mere-exposure effect whereby attitude objects receive increasingly favorable evaluations due to repeated sensory experience—is foundational to ideological support for the status quo. In Study 1, individual variation in familiarity bias predicted greater Right-Wing Authoritarianism. Existential threat was experimentally manipulated via the salience of international terrorism in Study 2, but was unsuccessful due to …

An Inquiry Into The Distinction Between Belief And Imagination, Maxwell M. Gatyas

Graduate Theses and Dissertations

Theories of mind typically see belief and imagination as distinct cognitive attitudes. While most admit that imagination is belief-like in many ways—e.g. in its capacity to guide action, cause emotional responses, and aid in decision-making processes—the popular view is to separate the two attitudes when constructing a theory of mental architecture. The similarities are not enough for theorists to admit that the two attitudes are indistinct. Imagination, then, is construed as an “analogue” of belief, similar in many ways, but nevertheless fundamentally different. In what follows I examine these methods of distinguishing between belief and imagination. My method of examination …

The Role Of Sharing And Information Type In Children's Categorization Of Privileged And Conventional Information, Helana Girgis

Graduate Theses and Dissertations

Categorization is an essential part of our daily lives and an integral part of humans’ ability to function and interact within society. There are large bodies of research that document children’s categorization in domains such as natural kinds, artifacts and human kinds. One domain that has not been investigated is children’s ability to categorize different types of information; specifically conventional information, shareable to others with no restrictions, and privileged information, shareable to only a few. Study 1 investigated 4- and 5-year-olds and adults’ ability to categorize conventional and privileged information. All participants correctly categorized both types of information equally well …

On The Evolutionary Origins Of Religious Belief, Robert Duane Howard

Graduate Theses and Dissertations

Religious belief is a byproduct of evolutionarily designed cognitive mechanisms. The ubiquity of religious belief and experience across human cultures is explained by our common human psychology; our domain-specific cognitive mechanisms give rise, collectively, to the phenomenon of byproduct religious belief/experience. In this thesis, I will examine what I call religion-generating cognitive mechanisms, and I will argue that byproduct raw god-beliefs are developed by cultures into refined god-beliefs. These refined god-beliefs are co-opted by evolutionary processes and are cultural adaptations. My conception of “religious belief” in terms of raw and refined god-beliefs allows a disambiguation of the term “religion,” and …

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 …

A Descriptive Study Of The Use Of Neurofeedback In Counseling, Khwlah Jamil Al-Ansari

Graduate Theses and Dissertations

This study examines neuro-counseling in the mental health field and the concept of neurofeedback training (NFB) as an intervention in the counseling profession. Numbers of studies have indicated that NFB may be effective in the field of counseling. The purpose of this survey study is to explore the use of neurofeedback in the field of counseling.

Additionally, the study used a quantitative descriptive survey research method and descriptive statistics. The survey was sent to members of the American Counseling Association (ACA), and 93 professionals participated. The majority of the sample was licensed professional counselors, professionals with a degree in counseling, …

A Manipulation Of Cognitive Restriction And Goal-Conflict: Mechanisms Underlying The Disinhibition Effect Of Eating Behavior, Kayla D. Skinner

Graduate Theses and Dissertations

People are often faced with a self-control dilemma whenever the attainment of a long-term goal would come at the expense of an alluring temptation. The goal-conflict model of eating (Stroebe, van Koningsbruggen, Papies, & Aarts, 2013) suggests that restrained eaters (i.e., chronic dieters) experience self-regulation failure (e.g., overeating, or disinhibition) due to inner competing goals of eating enjoyment and weight control. The current study examined these concepts in a sample of people classified as unrestrained eaters (N = 123), allowing for an investigation of restricted cognitive focus as a causal mechanism of disinhibited eating. A 2 (restraint condition: restriction, intuitive …

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 …

The Use Of Recollection Rejection In The Misinformation Paradigm, Kara Moore

Graduate Theses and Dissertations

Across three experiments, I investigated the role of recollection rejection in rejecting false suggestions using the misinformation paradigm. The use of model-based measurement of recollection rejection was extended to the misinformation paradigm. I manipulated two factors, delay and feedback, that are known to influence the use of recollection rejection. Recollection rejection was used to reject false suggestions in the misinformation paradigm. Manipulating delay time did not affect the acceptance of misinformation or the use of recollection rejection. Warning participants about false information reduced misinformation acceptance but did not lead to increased rates of recollection rejection. Collectively, these findings suggest an …

The Effects Of Maternal Information Transmission On Daughters' Responding To A Voluntary Hyperventilation Challenge, Ashley Arehart Knapp

Graduate Theses and Dissertations

Contemporary models of panic etiology would benefit from additional tests of how fear of internal cues is acquired. Drawing from literature suggesting parent-to-child verbal information transmission is one pathway by which fear of external stimuli is learned, the current study is designed to address the effects of this pathway on fearful responding to internal cues (i.e., somatic perturbation produced by a voluntary hyperventilation challenge). Specifically, 53 mothers of adolescent females between the ages of 10 and 14 years were randomly assigned to either share negative or positive information regarding their experience with a voluntary hyperventilation challenge prior to their daughters …

Effects Of Licensed And Unlicensed Negation On The Activation Of Negated Concepts, Kevin Autry

Graduate Theses and Dissertations

Research on the activation of negated concepts has demonstrated situations in which negated concepts are less active than non-negated concepts (e.g., MacDonald & Just, 1989) as well as situations where negated and non-negated concepts are equally active (e.g., Autry & Levine, 2012, in press). Based on the pragmatic inference hypothesis (Levine & Hagaman, 2008), the present experiments tested the hypothesis that the activation level of negated concepts is a function of the context in which they occur. In two experiments, the activation level of target concepts was measured following licensing or non-licensing contexts using lexical decision and reading times. Although …

The Impact Of Cognitive Behavior Techniques On The Vocational Identity Of Persons With Disabilities Receiving Ssi/Ssdi Benefits, James Joseph Quinn

Graduate Theses and Dissertations

This study examines the effects of Cognitive Behavior Therapy (CBT) on the vocational identity, self-efficacy, and vocational satisfaction of persons with disabilities receiving SSI/SSDI. This study was carefully planned to help persons with disabilities obtain employment. A review of the relevant literature was used to determine the need for the study and to support the study. Forty participants, all were enrolled into a vocational rehabilitation program were selected for the study. Threats to internal and external validity were taken into consideration and controlled for. They received CBT as a treatment intervention to change their beliefs and irrational thoughts about the …

Attention And Criminal Charge, Profile And Description: The Effect On Prospective Person Memory, Lindsey Nicole Sweeney

Graduate Theses and Dissertations

Prospective person memory is the ability to recognize and react to a missing or wanted individual that one has been asked to be on the lookout for in the future. Prospective person memory relies on several processes including face recognition, event-based prospective memory, and attention. Only recently has research on the role of visual attention on prospective person memory been examined. In this dissertation, the gap between prospective person memory and attention is addressed. Although research on prospective person memory is steadily increasing, the research in this area is still in its infancy and the exact memory mechanisms that affect …

A Conceptual Model Of Exploration Wayfinding: An Integrated Theoretical Framework And Computational Methodology, Matthew Lee Tenney

Graduate Theses and Dissertations

This thesis is an attempt to integrate contending cognitive approaches to modeling wayfinding behavior. The primary goal is to create a plausible model for exploration tasks within indoor environments. This conceptual model can be extended for practical applications in the design, planning, and Social sciences. Using empirical evidence a cognitive schema is designed that accounts for perceptual and behavioral preferences in pedestrian navigation. Using this created schema, as a guiding framework, the use of network analysis and space syntax act as a computational methods to simulate human exploration wayfinding in unfamiliar indoor environments. The conceptual model provided is then implemented …

Development And Implementation Of It-Enabled Business Processes: A Knowledge Structure View, Rick Brattin

Graduate Theses and Dissertations

As competitive pressures mount, organizations must continue to evolve their business processes in order to survive. Increasingly, firms are developing new IT-enabled business processes in response to rising competition, greater customer expectations, and challenging economic conditions. The success rate of these projects remains low despite much industry experience and extensive academic study. Managerial and organizational cognition represents a potentially fruitful lens for studying the design and implementation of IT-enabled business processes. This view assumes that individuals are information workers who spend their days absorbing, processing, and disseminating information as they pursue their goals and objectives. Individuals develop cognitive representations, called …

A Multimodal Approach For The Assessment Of Alexithymia: An Evaluation Of Physiological, Behavioral, And Self-Reported Reactivity To A Traumatic Event-Relevant Video, Sarah Jo Bujarski

Graduate Theses and Dissertations

Evidence suggests alexithymia is often relatively elevated among people suffering from posttraumatic stress symptoms (PTSS). Despite a growing body of research supporting this relation between alexithymia and PTSS, it is unclear whether alexithymia is a unique predictor of emotional reactivity relative to posttraumatic stress symptoms. Furthermore, existing literature is largely limited to retrospective, self-reported symptoms. Therefore, the current study employed a multimodal assessment strategy for measuring emotional reactivity in the context of posttraumatic stress. More specifically, self-report, behavioral, and physiological measures were used to measure emotional responding to a traumatic event-related stimulus among motor vehicle accident victims. It was hypothesized …

Temporal Shifts In Weapon Focus: Comparing Retrograde And Anterograde Effects, William Blake Erickson

Graduate Theses and Dissertations

When an eyewitness suffers an impairment of memory for a criminal's face because the criminal used a weapon during the commission of the crime, this impairment is called the weapon focus effect. Literature provides two explanations for how this effect arises: some implicate the narrowing of attentional cues to the weapon during the commission of a crime because arousal of the victim increases, while others claim that the weapon is merely a novel object in most everyday contexts, and novel objects demand more attention than contextually appropriate ones. The current study employed a simulated crime paradigm taking place in a …

Fighting The Current: Recalling Specific Self-Relevant Memories, John Walden Ransom

Graduate Theses and Dissertations

The present study was designed to address whether recalling specific autobiographical memories is more difficult when they are self-relevant compared to non-relevant. In recent years, a number of experimental studies have indicated that self-relevant memories are more likely to be recalled without a specific time frame or very much detail. Unfortunately, these findings have not been integrated into the popular executive resources theory of autobiographical memory recall or theories of independent semantic and episodic memory stores. This study tested the hypothesis that self-relevant memories will be accessed in the semantic store and therefore will require more executive resources to generate …

Perceptions Of Sexual Dangerousness: Accurate Identification Of Sexual Offenders From Static Photographs, Amber Jean Culbertson-Faegre

Graduate Theses and Dissertations

The present research expands understanding of the phenomenon of accurate identification of sexually dangerous men. Study 1 was designed to examine the influence of experience on accuracy of perceptions of sexual dangerousness. Receiving feedback about test trials increased accuracy on future trials at a marginally significant level. Study 2 was designed to determine the importance of specific facial features on these judgments. This study, however, failed to replicate the findings from the first study. Implications for Study 1, as well as possible explanations for Study 2 are discussed.
