The Effect Of Reliability Information And Risk On Appropriate Reliance In An Autonomous Robot Teammate, Andrew Talone

Electronic Theses and Dissertations

This research examined how information regarding a robot teammate's reliability and the consequences for mistakes made by a robot in its task influence reliance on the robot by a human teammate. Of interest in this research was the notion of appropriate reliance: relying on a robot teammate's decisions when it is performing well and not relying on its decisions when it is performing poorly. An experiment was conducted in which participants interacted with an autonomous robot teammate while performing a cordon and search operation within a virtual reality simulation environment. Participants were responsible for monitoring the perimeter of a search …

The Role Of Content Modality On The Likability Of An Online Communicator, Rebecca L. Pharmer

Honors Undergraduate Theses

With the growing popularity of social media platforms like Facebook, human interaction in online environments is increasing. As a result, social perceptions of the individuals "behind the screen" has become a topic that needs to be explored. The present study explores how the media platform (specifically Facebook post versus Video) affects perceptions of an individual with a controversial opinion. Potentially, the same content in a video format may increase the likability of the presenter in contrast to reading the same opinions in Facebook posts. The present study examined the role of alignment of opinion (agree vs. disagree with presenter) and …

Working Memory Capacity And Executive Attention As Predictors Of Distracted Driving, Jennifer Louie

Electronic Theses and Dissertations

The present study empirically examined the effects of working memory capacity (WMC) and executive attention on distracted driving. Study 1 examined whether a Grocery List Task (GLT) distractor would load onto WMC. Forty-three participants completed a series of WMC tasks followed by the GLT. They then completed two driving trials: driving without the GLT and driving while completing the GLT. It was hypothesized that WMC would positively correlate with GLT performance. A bivariate correlation indicated that WMC was positively associated with performance on the GLT. Study 2 tested a series of distractor tasks (GLT, Tone Monitoring, and Stop Signal) to …

Categorical Change: Exploring The Effects Of Concept Drift In Human Perceptual Category Learning, Andrew Wismer

Electronic Theses and Dissertations

Categorization is an essential survival skill that we engage in daily. A multitude of behavioral and neuropsychological evidence support the existence of multiple learning systems involved in category learning. COmpetition between Verbal and Implicit Systems (COVIS) theory provides a neuropsychological basis for the existence of an explicit and implicit learning system involved in the learning of category rules. COVIS provides a convincing account of asymptotic performance in human category learning. However, COVIS – and virtually all current theories of category learning – focus solely on categories and decision environments that remain stationary over time. However, our environment is dynamic, and …

Memory Of Words: A Categorization Task, Paulina Maxim

Honors Undergraduate Theses

Through the years, the Deese-Roediger-McDermott Paradigm has demonstrated to be a useful method of observing false memories from semantically related word lists. The present study was conducted fully online and measured memory performance dependent on categorization of words by using groups, as well as dragging words across the page as a form of interaction. In a 2 (Categorized, Non-Categorized) x 2 (Interactive, Non-Interactive) between-subject factorial experiment, 56 undergraduate students were shown 18 different lists of 15 associative words to be studied, one list at a time. Participants were given a free recall test immediately after studying each individual list. Participants …

Oculomotor Mechanisms Underlying Attentional Costs In Distracted Visual Search, Joanna Lewis

Electronic Theses and Dissertations

Performance consequences have been long established when humans multitask. This research concerns the impact of distraction on the attentional shifts during a task that underlies many cognitive processes and everyday tasks, searching for a target item among non-target items (e.g., scanning the road for potential collisions). There is evidence that increasing the mental workload by introducing additional tasks influences our ability to search our environment or interferes with processing fixated information. In the current studies, I aimed to evaluate the changes in gaze behaviors during visual search to evaluate how multitasking impairs our attentional processes. Participants completed a visual search …

Psychometric Properties Of A Working Memory Span Task, Juan M. Alzate Vanegas

Honors Undergraduate Theses

The intent of this thesis is to examine the psychometric properties of a complex span task (CST) developed to measure working memory capacity (WMC) using measurements obtained from a sample of 68 undergraduate students at the University of Central Florida. The Grocery List Task (GLT) promises several design improvements over traditional CSTs in a prior study about individual differences in WMC and distraction effects on driving performance, and it offers potential benefits for studying WMC as well as the serial-position effect. Currently, the working memory system is composed of domain-general memorial storage processes and information-processing, which involves the use of …

Eye Movements And Spatial Ability: Influences On Thinking During Analogical Problem Solving, Bradford Schroeder

Electronic Theses and Dissertations

Classic studies have examined the factors that influence the way in which people can solve difficult "insight" problems, which require creative solutions. Recent research has shown that guiding one's eye movements in a pattern spatially congruent with the solution improves the likelihood of formulating a spatial solution. The authors in this line of research argued that guiding eye movements in a pattern spatially equivalent to the solution of the problem yields an embodied cognitive benefit that aids problem solving. Specifically, guiding eye movements leads to the generation of a mental representation containing perceptual information that helps a problem solver mentally …

Understanding Human Performance And Social Presence: An Analysis Of Vigilance And Social Facilitation, Victoria Claypoole

Electronic Theses and Dissertations

Social facilitation is characterized by improved performance on simple, or well-known, tasks and impaired performance on complex, or unfamiliar, tasks. Previous research has demonstrated that the use of social presence may improve performance on cognitive-based tasks that are relevant to many organizational contexts, such as vigilance. However, to date, there has not been consolidation of the research regarding the different implementations of social facilitation, or any analysis indicating which types of social presence are best under varying conditions. The present dissertation describes three experiments that seek to contribute to a taxonomic framework of social facilitation. Experiment One statistically established a …

Pulse - A Consultation, Barry J. Mauer

Faculty Scholarship and Creative Works

On June 12, 2016, Omar Mateen killed 49 people and injured 53 at the Pulse Nightclub in Orlando, Florida. We may never know or understand what was in Mateen’s mind, but we can situate his attack within the history of eliminationism in America. Islamist terrorism is just part of a larger phenomenon: right wing eliminationism. But despite centuries of right wing eliminationist words and deeds in the U.S., there is little or no mainstream recognition of the phenomenon. Instead, we are treated to more denial, more distraction, more obfuscation. Until we look this problem squarely in the face, it will …

Real Loneliness And Artificial Companionship: Looking For Social Connections In Technology, Fernando L. Montalvo

Honors Undergraduate Theses

Loneliness among older adults is a problem with severe consequences to individual health, quality of life, cognitive capacity, and life-expectancy. Although approaches towards improving the quality and quantity of social relationships are the prevailing model of therapy, older adults may not always be able to form these relationships due to either personality factors, decreased mobility, or isolation. Intelligent personal assistants (IPAs), virtual agents, and social robotics offer an opportunity for the development of technology that could potentially serve as social companions to older adults. The present study explored whether an IPA could potentially be used as a social companion to …

The Relationship Between Sleep, Working Memory, And Decision Making In Young And Old Adult Populations, Melissa G. Merz

Honors Undergraduate Theses

Sleep is known to influence basic tasks concerning working memory, reaction time and executive functioning (Silva, Wang, Ronda, Wyatt, & Duffy, 2010; Nebes, Buysse, Halligan, Houck, & Monk, 2009). However, the amount that sleep influences these functions varies from study to study possibly due to differences in age and task design. Aim 1A of this study is to determine if sleep quality affects working memory. Aim 1B of this study is to determine if age affects sleep quality and working memory in comparison of young and old adult populations. Finally, Aim 2 of this study is to determine if there …

Comparing Sexual Cognition And Risk By Gender, Jacquelynne Dauk

Honors Undergraduate Theses

The ways in which sexuality is perceived among members of society has substantial effects in regards to overall health and well-being. The current study investigates not only the nature of sexual cognition but also the differences in cognition in regards to participant genders. More specifically, this study seeks to investigate the differences in sexual attitudes and thoughts among different genders that may lead to different forms of sexual risk. In order to identify these differences, societal influences such as social roles, parenting styles, and sexual education are all examined in regards to gender. Factors such as age and demographics were …

The Role Of Accounts And Apologies In Mitigating Blame Toward Human And Machine Agents, Kimberly Stowers

Electronic Theses and Dissertations

Would you trust a machine to make life-or-death decisions about your health and safety? Machines today are capable of achieving much more than they could 30 years ago—and the same will be said for machines that exist 30 years from now. The rise of intelligence in machines has resulted in humans entrusting them with ever-increasing responsibility. With this has arisen the question of whether machines should be given equal responsibility to humans—or if humans will ever perceive machines as being accountable for such responsibility. For example, if an intelligent machine accidentally harms a person, should it be blamed for its …

Testing Of Wrist-Worn-Fitness-Tracking Devices During Cognitive Stress: A Validation Study, Nicole S. Chudy

Honors Undergraduate Theses

The intent of this thesis was to test if one of the many fitness-tracking devices, Microsoft’s Band 2 (MSB2), is accurate and reliable in detecting changes in Heart Rate (HR) and R-R intervals, during the repeated trial of two conditions of a working-memory test known as the N-Back. A 2 (devices: ECG, MSB2) × 4 (epochs: baseline 1, 1-back task, baseline 2, 3-back task) repeated measures factorial design was conducted. The participants were simultaneously equipped to the MSB2 and an electrocardiogram (ECG). The results of this study validated the MSB2 for the use in a cognitive task. The study suggests …

Beyond Compliance: Examining The Role Of Motivation In Vigilance Performance, Alexis Neigel

Electronic Theses and Dissertations

Vigilance, or sustained attention, is the capacity to attend to information for a prolonged period of time (Davies & Parasuraman, 1982; Jerison, 1970; Warm, 1977). Due to limitations of the human nervous system, as well as the environmental context, attention can begin to wane over time. This results in a phenomenon referred to as the vigilance decrement, or a decline in vigilance performance as a function of time. The vigilance decrement can manifest as poorer attention and is thusly associated with poor performance, which is defined behaviorally as more lapses in the detection of critical signals and an increase in …

Gamification Of Visual Search In Real World Scenes, Alyssa Hess

Electronic Theses and Dissertations

Gamification, or the application of game-like features in non-game contexts, has been growing in popularity over the last five years. Specifically, the successful gamification of applications (such as Waze, Foursquare, and Fitocracy) has begun a spike in gamification of more complex tasks, such as learning to use AutoCAD or Photoshop. However, much is unknown about the psychological mapping of gamification or how it translates to behavioral outcomes. This dissertation aims to compare three distinct styles of gamification (avatars, points and feedback, and leaderboards) onto the three basic psychological needs (autonomy, competence, and relatedness). It will assess behavioral outcomes on a …

An Exploration Of The Feasibility Of Functional Near-Infrared Spectroscopy As A Neurofeedback Cueing System For The Mitigation Of The Vigilance Decrement, Gabriella Hancock

Electronic Theses and Dissertations

Vigilance is the capacity for observers to maintain attention over extended periods of time, and has most often been operationalized as the ability to detect rare and critical signals (Davies & Parasuraman, 1982; Parasuraman, 1979; Warm, 1984). Humans, however, have natural physical and cognitive limitations that preclude successful long-term vigilance performance and consequently, without some means of assistance, failures in operator vigilance are likely to occur. Such a decline in monitoring performance over time has been a robust finding in vigilance experiments for decades and has been called the vigilance decrement function (Davies & Parasuraman, 1982; Mackworth, 1948). One of …

Examining The Role Of Cardiovascular And Cognitive Fitness In Goal-Directed Aiming Across The Lifespan, Michael Rupp

Electronic Theses and Dissertations

Older adults experience more difficulties completing goal directed movements than younger adults. The reasons for this have not been completely elucidated within the research literature; however, it is thought that age related movement differences are due to at least one of three possible reasons. The current study investigated the influence of these three hypotheses: (1) biomechanical changes (limbs, joints, or muscles), (2) sensory feedback processing ability, or (3) differences in overall movement strategy on movement kinematics. Additionally, physical activi-ty is known to improve both physical and cognitive functioning and staying cognitively active may also attenuate age-related declines in cognitive ability; …

Do Multiple Conditions Elicit The Visual Redundant Signals Effect In Simple Response Times?, Ada Mishler

Electronic Theses and Dissertations

The redundant signals effect, or redundancy gain, is an increase in human processing efficiency when target redundancy is introduced into a display. An advantage for two visual signals over one has been found in a wide variety of speeded response time tasks, but does not always occur and may be weakened by some task parameters. These disparate results suggest that visual redundancy gain is not a unitary effect, but is instead based on different underlying mechanisms in different tasks. The current study synthesizes previous theories applied to redundancy gain into the three-conditions hypothesis, which states that visual redundancy gain depends …

Examining Energetic And Structural Components Of Knowledge Of Result Using A Vigilance Paradigm, Nicholas Fraulini

Electronic Theses and Dissertations

Vigilance, or the ability to maintain attention to stimuli over a prolonged period of time (Davies & Parasuraman, 1982; Warm & Jerison, 1984), has been a troublesome research topic since World War II. Scientists have sought to counteract performance declines in vigilance tasks by training observers on these tasks. Though an extensive literature has been developed to examine the effectiveness of these techniques, the mechanisms by which many forms of vigilance training help performance are largely unknown. The present dissertation seeks to further the understanding of how two forms of training for vigilance, practice and knowledge of result, function to …

The Effects Of Cerebrovascular Aging On Sleep Quality In A Sample Of Aging Adults, Chelsea Tia Mapp

Honors Undergraduate Theses

Cerebrovascular burden (CVB) is a significant factor among the aging population. Age-related cognitive decline is an important social and economic issue, and understanding the mechanisms has clinical implications, both in selecting potential therapies and in choosing specific modifiers for their evaluation. In summary, past work suggests that high CVB is one source of variance in neurovascular functioning among older adults. High CVB and associated brain-changes have been identified as causes of age-related changes and it may be that high CVB is a correlate of age-related changes in sleep quality. The primary hypothesis to be tested is that cerebrovascular burden measured …

Free To Be Accountable: Extended Self As A Moderator Of Cheating Among Those Primed With Determinism, Vincent M. Iula

Honors Undergraduate Theses

The idea that free will may be an illusion has been a source of great concern. It has led to suggestions that it may be wise to avoid public discussion of this topic lest it lead to a general moral decay. This concern has seemingly been supported by research demonstrating that individuals, when primed with the notion they lack free will, tend to cheat more and prefer less retributive punishment. The current research suggests that these effects can be moderated by the introduction of a second prime. In experiment one, participants believed they were being tested on note-taking and the …

The Study Of The Adverse Effects Of Childhood Maltreatment, Katie A. Kennie

Honors Undergraduate Theses

This study explores the link between the presence of childhood trauma and adult criminal behavior. In this study, four distinct categories of childhood trauma (physical abuse, sexual abuse, psychological abuse, and neglect) were examined. In addition, this study conducts a comparative analysis of the United States crime rate with that of Switzerland and Japan. This study examines and compares the policies utilized in ensuring the protection of child welfare. The ultimate goal is to provide research which may build a foundation that will assist in creating and improving policies which will ensure a child's psychological health.

Individual Differences In Eyewitness Testimony, Noel A. Cal

Honors Undergraduate Theses

Eyewitness testimony plays a crucial role in the justice system. Misidentification from eyewitnesses was reported in 70% of 300 DNA exonerations of wrongfully convicted individuals (Wixted et al., 2015). Similarly, many convicts can also be set free because of juror’s faulty eyewitness recall during examination. Previous research indicated that females are more reliable in recall than men. However, these findings were not extensively examined with regards to time delay prior to the trial. Thus, it is important to systematically examine the various factors that influence eyewitness testimony.

The present study was designed to empirically examine the effects of gender, interview …

Correlations Between Sexual Imagery And Sexual Cognitions, Jennifer L. Mcdonnell

Honors Undergraduate Theses

Analyzing the relationship between the visual imagery used in music videos, and the sexual cognition of viewers. Sexual cognition is the awareness of one's own sexual behavior, and its implications. The visual content of music videos was analyzed focusing only on the imagery used. The Heterosexual Script (Jhally, 2007) in particular is observed in most music videos, highlighting the sexual objectification of women and the dominant role of males. The direction of causality between the visual imagery and sexual cognitions can only be speculated using a number of theories, namely cognitive dissonance (Festinger, 1957), cultivation theory (Gerbner et al., 1994), …

Sexual Content In Music Lyrics And Their Effects On Sexual Cognition, Nicole Nowotny

Honors Undergraduate Theses

The purpose of this study was to examine the sexual content found in music lyrics of different genres and their relationship to specific sexual cognitions. The study included 902 participants, both male and female, belonging to various ethnic backgrounds, ages 18 and up. It was hypothesized that listening to music containing frequent sexual lyrics will have an affect on men and women’s sexual cognitive beliefs. Results indicated that there was a relationship between frequency of sexually explicit lyrics and views on sexual cognitions. The breakdown by genre shows a more detailed relationship between the lyrics and sexual cognitions. Overall, the …

Evaluating Competition Between Verbal And Implicit Systems With Functional Near-Infrared Spectroscopy, Troy A. Schiebel

Honors Undergraduate Theses

In category learning, explicit processes function through the prefrontal cortex (PFC) and implicit processes function through the basal ganglia. Research suggested that these two systems compete with each other. The goal of this study was to shed light on this theory. 15 undergraduate subjects took part in an event-related experiment that required them to categorize computer-generated line-stimuli, which varied in length and/or angle depending on condition. Subjects participated in an explicit "rule-based" (RB) condition and an implicit "information-integration" (II) condition while connected to a functional near-infrared spectroscopy (fNIRS) apparatus, which measured the hemodynamic response (HR) in their PFC. Each condition …

The Effect Of Neighborhood Size And Morphology In The Chinese Language, Long Nguyen

Honors Undergraduate Theses

The Neighborhood Size Effect (NSE), characterized as the effect in word determination based on changing one orthographic aspect of that word. The amount of words that can be created through such manipulation is called a neighborhood size (NS). Number of other factors such as frequency, how often a word appears and morphology, the combination of meaningful word units, have been suggested to have an overriding effect on NSE. In addition, there is a lack of research on NSE with non-alphabetical languages such as Chinese, which uses characters comprising of a multitude of semantic or phonetic markers. In this experiment, participants …

Individual Differences Of Directed Forgetting, Griselda Alavez

Honors Undergraduate Theses

The present study set out to evaluate the relationship between list-method directed forgetting and one’s individual differences. Previous research has found personality and emotion as having an influence in how well participants were able to intentionally forget stimuli. Participants were split into a remember group and a forget group of 22 each and tasked to memorize a list of 10 words. They were then given a free recall test and the results for individual differences such as Need for Cognition, Mini-IPIP personality test, and Beck’s Depression Inventory were analyzed. Our first hypothesis presumes that participants in the forget group will …
