The Impact Of Evaluative Pressure And Higher Working Memory Capacity On Sensorimotor Skill Performance., Lauren Grant

College of Arts & Sciences Senior Theses

Underperformance in high-pressure situations, commonly known as choking under pressure, has been well-documented in the literature. For well-learned sensorimotor skills, such as sports, choking is thought to occur because individuals devote explicit attention to the steps of the skill, which disrupts performance. The current study examines how the type of pressure situation an individual experiences, and individual differences in working memory capacity, influence choking on a sensorimotor skill. Participants (N = 96) performed a Sensorimotor Reaction Time Task (SRTT) either under monitoring pressure, outcome pressure, or no pressure (control). High working-memory individuals performed significantly worse while completing the SRTT under …

Can Dolphins Cooperate To Solve A Novel Task?, Kelley Ann Winship

Master's Theses

Bottlenose dolphins cooperate in a variety of contexts, including foraging,acquiring mates, playing, and assisting distressed conspecifics. To better understand the capacity for cooperative behaviors, animals are often given tasks that require pairs of animals to coordinate their actions in order to receive a reward. This paper reports the results of an aquatic version of one such task: cooperative rope-pulling. Three groups of captive bottlenose dolphins (Tursiops truncatus) were given an apparatus that could most easily be opened by the two animals working together. Two untrained adult males at one location were successful in opening the apparatus together, sharing …

Age And Iq As Potential Moderators In The Relation Among Endopheonotypes And Expressed Behaviors In Children With Autism Spectrum Disorder, Elizabeth Clara Fair

Master's Theses

The current study examined how certain endophenotypes (i.e., local processing ability, mental flexibility, planning, and disinhibition /inhibition) are related to specific expressed behaviors (i.e., acting out behaviors, social insight deficits, social contact problems, anxious/rigid behaviors, and stereotypical behaviors) that are commonly found in children with ASD. In addition, this study examined whether these associations are modified by age or IQ. Participants consisted of 29 children (ages 7 to 16 years) with ASD and their parents. Parents completed the Children’s Social Behavior Questionnaire (CSBQ) to assess their child’s variety of expressed behaviors. The children were given the Kaufman Brief Intelligence Test—Second …

Bottlenose Dolphin (Tursiops Truncatus) Behaviors In The Presence Of Active And Non-Active Shrimp Trawlers In The Mississippi Sound, Crysta M. Lorenz

Honors Theses

Bottlenose dolphins, Tursiops truncatus, are reported to have close associations with shrimp trawlers worldwide. The goal of this study was to assess differences in the behavior for bottlenose dolphins between activity states of shrimp trawlers in the Mississippi Sound. During active trawling, nets are actively gathering the catch closely behind the trawler, which provide feeding opportunities for bottlenose dolphins. Non-active groups are not able to take advantage of feeding prospects and display fewer feeding behaviors and maintain a farther distance than active trawler groups. Video of trawlers were collected from the Mississippi Wild Dolphin Project and analyzed for feeding …

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 …

Central Auditory Processing And The Link To Reading Ability In Adults, Lisa M. Brody

Honors Scholar Theses

What makes someone a good reader? What makes someone a poor reader? The root biological marker of reading ability has yet to be determined. Many scientists agree that phonological awareness, the understanding of speech sounds, and phonological decoding are key components of reading ability (Melby-Lervag, Lyster, & Hulme, 2012). In addition to this, new research suggests that the auditory system, specifically the timing of auditory processing in the brain, provides a crucial platform that supports the development of reading ability (Banai et al., 2009). This thesis provides empirical data to support the link between reading skill …

Distinguishing Originality From Creativity In Adhd: An Assessment Of Creative Personality, Self-Perception, And Cognitive Style Among Attention-Deficit/Hyperactivity Disorder Adults, Jean-Pierre J. Issa

Creative Studies Graduate Student Master's Theses

Debates over whether Attention-Deficit/Hyperactivity Disorder (ADHD) relates to high levels of creativity have been hampered by a lack of rigor when defining creativity. The purpose of the present study was to go beyond the rhetoric by empirically investigating creative personality, creative self-perception, and cognitive style among 49 ADHD adults. Comparative analysis to studies of non-ADHD samples revealed distinctive tendencies: A mean group score of 115.71 (SD=18.02) on the Kirton Adaption-Innovation Inventory (KAI) indicated preferences for originality, nonconformity, paradigm-breaking, and low efficiency that was over one standard deviation higher than average non-ADHD population scores. Combined inattentive/hyperactiveimpulsive subtypes (n …

How To Go Beyond The Body: An Introduction, Guy Dove

Faculty and Staff Scholarship

Embodied cognition represents one of most important theoretical developments in contemporary cognitive science. Many cognitive processes appear to be influenced by body morphology, emotions, and sensorimotor systems. This perspective is supported by an ever increasing collection of empirical studies that fall into two broad classes: one consisting of experiments that implicate action, emotion, and perception systems in seemingly abstract cognitive tasks and the other consisting of experiments that demonstrate the contribution of bodily interaction with the external environment to the performance of such tasks.

Now that embodied cognition is fairly well established, the time seems right for assessing its further …

Experience-Specific And Domain-General Effects On Simple And Complex Meter Processing, Sangeeta Gupta

UNLV Theses, Dissertations, Professional Papers, and Capstones

Our ability to process rhythmic patterns is constrained by the complexity of its interval structure. The goal of the present study was to explore the cognitive demands and neural mechanisms for processing simple and complex meters, and the extent to which they are modulated by culture-specific experience. The first experiment explored the argument that perception of rhythm is guided by a domain-general ability to process quantity, and that processing simple and complex meter rhythms requires different cognitive strategies. Rhythm perception was assessed by testing listeners’ ability to detect disruptions in simple and complex meter melodies. Proficiency with numerosity judgments was …

Electrophysiological Changes In P200 Latency And Amplitude Of Jittered Orientation Visual Integration Task In Healthy Participants: A Multi-Block Design Eeg Study, Monika M. Rozynski, Chi-Ming Chen

Honors Scholar Theses

Visual integration, the ability to fuse environmental information such as light, color, shades, and motion to form a representation of a whole cohesive higher-order visual image, is impaired in persons with schizophrenia. Little is known how the P200 component, an event-related potential (ERP) in the parieto-occipital region, is affected in persons with schizophrenia while they perform visual integration tasks, when compared to healthy persons. This study administered Gabor contours that varied in high and low degrees of orientational jitter through the Jitter Orientation Visual Integration (JOVI) task to investigate visual integration by analyzing latency and amplitude of the P200 component. …

Training Tutors To Use A Time Delay Procedure To Increase Vocal Manding In Children With Autism, Chelsea Roberts

Honors Theses

Learning how to spontaneously mand, or request without prompting, can be difficult for children diagnosed with developmental disabilities. Previous research has shown that the implementation of a time-delay procedure aids in increasing spontaneous mands with these children (Charlop, Shreibman, & Thibodeau, 1985). The goal of this study was to increase vocal mands in children with developmental disabilities with a time-delay procedure by training their undergraduate tutors, using Behavioral Skills Training (BST), how to implement the procedure in naturally occurring opportunities. The study used a multiple baseline across participants design. The intervention used in this study can help children with developmental …

The Rise Of Adhd And Effects Of Alternative Treatment In Adolescents, Jennifer Villarina

Scholarly and Creative Works Conference (2015 - 2021)

Attention deficit hyperactivity disorder (ADHD) is a syndrome that makes it difficult for people to focus, control behavior and regulate activity. Many with ADHD move constantly and are impulsive. They cannot seem to follow directions and are easily bored or frustrated with tasks. Although these behaviors are normally observed in children, they are more severe in those with ADHD. The symptoms of ADHD make it difficult for children to function at school and home. Exposure to toxins, injury to the brain and imbalance of neurotransmitters can affect the development of the brain (LeFever, Arcona & Antonuccio, 2003). The most common …

Can Motivated Cognition Exacerbate A Bias?, Luis O. Camacho, Saera R. Khan

Creative Activity and Research Day - CARD

This study examined the relationship between the need for cognition and impression formation, particularly with common biases. Upon listening to a speaker with either a heavy Japanese or Los Angeles accent, participants rated the speaker on how well-informed they believed she appeared to be on the subject she spoke about and on intelligence. Despite the need for cognition, speakers with a Los Angeles accent were rated less favorably on intelligence, compared to Japanese accented speakers. However, the high need for cognition participants utilized a stereotype in impression formation, as their ratings for both speakers resonated with the speaker’s respective stereotype. …

The Relationship Between Emotional Contagion And Mood State, Kayleigh-Farrell Crow

Scholarly and Creative Works Conference (2015 - 2021)

Emotions can often be transferred from one person to another. It has been assumed that the strength and impact of contagious emotions can depend largely on the susceptibility of the individual. This concept has led to the idea of emotional contagion, or “the tendency to automatically mimic and synchronize facial expressions, vocalizations, postures and movements with those of another person, and consequently, to converge emotionally”, as defined by Hatfield, Cacioppo & Rapson (1992). The present study will examine the influence of certain emotions and the increased probability for contagion to occur. Specifically, this study will explore the emotional strengths of …

Understanding Tendencies Of Aggressive Behavior And Cognition As Related To Alcohol Use And Intimate Partner Violence, Taylor D. Thomas Ms.

Honors College Theses

The term intimate partner violence (IPV) refers to any act of aggression (physical or emotional) committed within an intimate relationship by one partner against the other, regardless of gender, sexual intimacy, or sexual orientation. One of the leading risk factors for IPV is the regular abuse of alcohol (National Coalition Against Domestic Violence, 2014). High levels of alcohol consumption predict an increase in aggression in individuals with aggressive dispositions (Barnwell et al., 2006). Extensive research exists on the relationship between alcohol use and IPV, yet there is a dearth in the literature investigating the complexities of the alcohol use-IPV relationship …

The Relationship Between Competitive Trait Anxiety And Optimism In College Aged Individuals, Allison M. Heiskell

Honors College Theses

The purpose of this study was to examine the relationship between competitive trait-anxiety and optimism in college students. A sample of 112 undergraduate students from a university in the Southeast completed three questionnaires: a demographics survey, a Life Orientation Test and a Sport Competition Anxiety Test. The data werethen analyzed using descriptive and inferential statistics to determine if a relationship exists. The hypothesis was that there would be a negative correlation between competitive trait anxiety and optimism levels in college students. This meant that as trait-anxiety in an individual increased, the optimism level decreased. It was found that a statistically …

Using The Stroop Effect To Examine The Effect Of Words To Which Humans Are Sensitive On Cognitive Conflict, Stacia Fritz

Honors College Theses

The purpose of experiment one was to test the effects of drink consumed (glucose, artificial sweetener, or water) and stimuli (food or non-food) on cognitive conflict. Glucose has been known to better cognitive functioning, and preoccupation with food worsens cognitive functioning on a food-related task. We hypothesized that participants who received glucose and non-food stimuli will perform best on the cognitive tests, and participants who received aspartame and food-stimuli will perform worst on the cognitive tests. Participants were each given an 8 oz. drink to consume, shown six minutes of stimuli, performed an “X-word” Stroop test, shown six more minutes …

Good Dog! Applications Of Dog Science, Brenden Wall, Anthony Bohner, Jeffrey Toraason, Ellen Furlong, Faculty Advisor

John Wesley Powell Student Research Conference

Each year 6 to 8 million pet dogs enter shelters, and unfortunately, many are returned to shelters, or euthanized, due to behavioral problems. Many behavioral problems can be alleviated if dogs get exercise; however, some owners cannot provide dogs sufficient exercise. Further, some dogs may be physically unable to exercise. One possible solution is to provide dogs with mental exercise. We are currently developing a series of touchscreen computer tasks with the hope that they provide mental stimulation and can be made available to owners via a tablet application. As of now, a few dogs in our lab have learned …

Current Methods And Future Directions Regarding Working Memory Training Research, Emily G. Wright

Undergraduate Distinction Papers

Cognitive training is the process through which individuals perform a series of computerized tasks over a period of weeks for the purpose of improving a variety of cognitive abilities. Cognitive training is important in commercial, clinical, and educational fields alike, considering the possibilities of improving and sustaining cognitive abilities in both typically developing and cognitively deficient populations. The present review assesses cognitive training paradigms targeting working memory. Working memory is a predictor of academic achievement and is closely related to mechanisms of higher cognition. In particular, the present review focuses past studies which have investigated the effects working memory training …

Fluid Grouping: Quantifying Group Engagement Around Interactive Tabletop Exhibits In The Wild, Florian Block, James Hammerman, Michael Horn, Amy Spiegel, Jonathan Christiansen, Brenda Phillips, Judy Diamond, E Margret Evans, Chia Shen

Department of Educational Psychology: Faculty Publications

Interactive surfaces are increasingly common in museums and other informal learning environments where they are seen as a medium for promoting social engagement. However, despite their increasing prevalence, we know very little about factors that contribute to collaboration and learning around interactive surfaces. In this paper we present analyses of visitor engagement around several multi-touch tabletop science exhibits. Observations of 629 visitors were collected through two widely used techniques: video study and shadowing. We make four contributions: 1) we present an algorithm for identifying groups within a dynamic flow of visitors through an exhibit hall; 2) we present measures of …

Electrophysiological Changes Of N100 Latency And Amplitude In Healthy Participants Performing The Jitter Orientated Visual Integration Task: A Multi-Block Design Study, Fariya Naz

University Scholar Projects

The present study investigated the differences in processing during visual integration in healthy adults. The visual N100 indexes early visual discrimination and in this case, was hypothesized to show differences in both latency and amplitude depending on the level of difficulty which corresponds to orientational jitter in a visual integration task. Four blocks with pseudo-random levels of jitter were presented to participants in the Jitter Oriented Visual Integration (JOVI) task. Results looking at the Oz channel showed significant reduction in amplitude in the visual N100 during the more difficult levels condition of the task. The multi-block design, originally expected to …

Password Strength Analysis: User Coping Mechanisms In Password Selection, Brian Thomas Curnett

Open Access Theses

The security that passwords provide could be seriously flawed due to the way people cope with having to memorize and recall their passwords. The National Institute of Standards and Technology (NIST) standard that is used to measure the password strength, known as entropy, is designed for a single use and does not consider that users may choose to keep parts of their password across password changes. This study shows that a portion of users keep some information from previous passwords across changes. These habits which will be called coping mechanisms that over time serve to erode the protection provided by …

Seeing People, Seeing Things: Individual Differences In Selective Attention, Miranda May Mcintyre

Open Access Theses

Individuals differ in the extent to which they attend to their physical and social environments, but little empirical work has measured these differences at a cognitive level. To address this gap, two studies explored the association between attentional processes and Person and Thing Orientations. The first study measured visual selective attention toward person- and thing-related image components. In the second study, participants provided written responses about a set of images; linguistic analyses were conducted to assess attentional bias toward interest-congruent content. The results from both studies support motivated attention as a process through which interests in physical and social environments …

The Effects Of Emotional Arousal On False Recognition In Alexithymia, Anthony N. Correro

Master's Theses (2009 -)

Alexithymia is a personality trait characterized by difficulties identifying feelings, difficulties describing feelings, and an externally oriented thinking style (EOT). Further, individuals with alexithymia experience chronic physiological arousal. Prior research has shown that non-clinical participants with alexithymic traits cannot subjectively recognize increased arousal in response to viewing an arousing video. Yet, these individuals will still experience physiological arousal and will still have arousal-induced memory modulation. No studies to date have examined arousal effects on false memory in alexithymia. The Deese-Roediger-McDermott (DRM) paradigm examines false memory by introducing words associated with a non-presented `theme' word (i.e., critical lure) as memoranda, which …

Invariant Two Component Structure Of The Rbans, Elisabeth M. Vogt

Master's Theses (2009 -)

The Repeatable Battery for the Assessment of Neuropsychological Status (RBANS: Randolph, 1998, 2012) is a brief neurocognitive instrument used to evaluate cognitive functioning in clinical settings. While this test is used regularly, investigation of the factor structure has resulted in inconsistent findings across samples. It was hypothesized that inconsistent RBANS dimensional structures are the result of methodological differences and not solely due to unique sample characteristics. The present study utilized empirically supported extraction criteria (Parallel Analysis; Minimum Average Partial Procedure) and uniformly investigated five samples. RBANS data from four samples were previously published (Carlozzi, Horner, Yang, & Tilley, 2008; Duff, …
