Security-Enhanced Serial Communications, John White, Alexander Beall, Joseph Maurio, Dane Fichter, Dr. Matthew Davis, Dr. Zachary Birnbaum

Military Cyber Affairs

Industrial Control Systems (ICS) are widely used by critical infrastructure and are ubiquitous in numerous industries including telecommunications, petrochemical, and manufacturing. ICS are at a high risk of cyber attack given their internet accessibility, inherent lack of security, deployment timelines, and criticality. A unique challenge in ICS security is the prevalence of serial communication buses and other non-TCP/IP communications protocols. The communication protocols used within serial buses often lack authentication and integrity protections, leaving them vulnerable to spoofing and replay attacks. The bandwidth constraints and prevalence of legacy hardware in these systems prevent the use of modern message authentication and …

The Effects Of Divided Attention In Free Recall: Affecting Trace Accumulation By Dividing Attention, Anne Olsen

USF Tampa Graduate Theses and Dissertations

How environmental information stores in memory directly affects our ability to retrieve the information. This thesis investigates the effects that dividing attention during study has on the storage of contextual information. Through several experiments, participants were asked to study and later recall word lists using a mixed-pure design with strengtheners varying as either repetition or study time. Experiment 1 investigates the effects of divided attention on the formation of inter-item associations and Experiments 2-6 manipulate strengthening item and context information in a memory trace when cognitive load is strained at various levels. Experimental results indicated that dividing attention during study …

Temporal And Spatial Properties Of Orientation Summary Statistic Representations, Jacob S. Zepp

USF Tampa Graduate Theses and Dissertations

The aim of the current work was to determine the amount of information that contributes to the formation of summary statistical representations (SSRs), as well as the time course over which these representations are formed. While the prevailing interpretation of SSRs within literature is that the summaries are formed through a compulsory rapid integration across all information in a scene, debate exists on the necessity of this unique processing mode. To investigate the formation of SSRs, two experiments were conducted. In the first, results from an orientation averaging task were compared to results from a whole-report task, over equivalent stimulus …

Sound Judgment: Review Of Noise: A Flaw In Human Judgment (2021) By Daniel Kahneman, Olivier Sibony, And Cass R. Sunstein, Anne Kelly

Numeracy

In Noise: A Flaw in Human Judgment (2021), Daniel Kahneman, Olivier Sibony, and Cass R. Sunstein convincingly demonstrate the pervasiveness and harmfulness of unwanted internal variability or noise. Using examples from both public and private sectors to demonstrate the quality and limits of the judgments we make, they argue that, despite objections based on possible cost, difficulty, and dehumanization, the reduction of noise is imperative for the fairness and equitability of systems upon which we depend.

Influences Of Sentence Context And Individual Differences In Lexical Quality On Early Phonological Processing During Silent Reading, Sara Milligan

USF Tampa Graduate Theses and Dissertations

The current thesis investigates the role of sentence context and individual differences in the quality of sub-lexical representations of words in activation of phonological forms during silent reading. More specifically, this study aims to determine how these situational and participant-level factors influence the use of phonology to aid word recognition during parafoveal processing, before a reader directly fixates the word. Therefore, I manipulated sentence constraint in two eye tracking during reading experiments (one using real-word and one using pseudoword parafoveal previews) that utilized the gaze-contingent boundary paradigm (Rayner 1975) and measured individual’s scores on assessments of spelling ability, phonological decoding …

Surveying The Landscape Of Numbers In U.S. News, John Voiklis, Jena Barchas-Lichtenstein, Bennett Attaway, Uduak G. Thomas, Shivani Ishwar, Patti Parson, Laura Santhanam, Isabella Isaacs-Thomas

Numeracy

The news arguably serves to inform the quantitative reasoning (QR) of news audiences. Before one can contemplate how well the news serves this function, we first need to determine how much QR typical news stories require from readers. This paper assesses the amount of quantitative content present in a wide array of media sources, and the types of QR required for audiences to make sense of the information presented. We build a corpus of 230 US news reports across four topic areas (health, science, economy, and politics) in February 2020. After classifying reports for QR required at both the conceptual …

Early Indicators Of Cognitive Dysfunction: The Role Of Mild Behavioral Impairment, Hillary J. Rouse

USF Tampa Graduate Theses and Dissertations

Older age is associated with an increased risk for cognitively impairing diseases such as dementia. Despite significant research to find ways to cure this disease, there has been little success. However, a critical need when an intervention is discovered is a need to find ways to identify people who are at the greatest risk of developing dementia earlier in the disease process so that interventions can be implemented at that time. This could potentially lessen their risk or delay when they are diagnosed. Using longitudinal data from the National Alzheimer’s Coordinating Center (NACC), the aims of this current dissertation were …

Directing Attention In Second Language Phonological Contrast Learning, Laura Conover

USF Tampa Graduate Theses and Dissertations

Why are some people better at learning new languages than others? There is a rich body of research examining this issue from multiple perspectives and at all levels of language. This study attempts to add to that knowledge at the most fundamental level of language by examining potential influences on the learning of novel phoneme contrasts. The purpose of this study was to explore whether individual differences in attentional capabilities would help adults learn a non-native phonological contrast, and whether providing explicit directions that would guide the learners’ attention could help boost their performance. VCV recordings of the Thai /p/ …

Review Of Innumeracy In The Wild: Misunderstanding And Misusing Numbers By Ellen Peters, Gizem Karaali

Numeracy

Ellen Peters’s new book Innumeracy in the Wild: Misunderstanding and Misusing Numbers (Oxford University Press, 2020) is a whirlwind tour of psychological research on numeracy and its interactions with decision-making. The book is packed full of convincing arguments about the impact of numeracy and innumeracy on people's decisions and life outcomes, piles of supporting evidence and relevant references, and detailed expositions of multitudes of research results. Thus, it can serve the motivated reader well as a comprehensive literature review of psychologically oriented research on numeracy and decision-making.

Better News About Math: A Research Agenda, Jena Barchas-Lichtenstein, John Voiklis, Laura Santhanam, Nsikan Akpan, Shivani Ishwar, Bennett Attaway, Patti Parson, John Fraser

Numeracy

Numeracy is not a luxury: numbers constantly factor into our daily lives. Yet adults in the United States have lower numeracy than adults in most other developed nations. While formal statistical training is effective, few adults receive it – and schools are a major contributor to the inequity we see among U.S. adults. That leaves news well-poised as a source of informal learning, given that news is a domain where adults regularly encounter quantitative content. Our transdisciplinary team of journalists and social scientists propose a research agenda for thinking about math and the news. We engage here in a dialogue …

The Immediate Effect Of A Brief Mindfulness Intervention On Attention And Acceptance, Xiaoqian Yu

USF Tampa Graduate Theses and Dissertations

Given the increased popularity of mindfulness in both the clinical settings and the general public, it is important to understand the active mechanisms of mindfulness. Mindfulness practice (MP) involves two active components, attention regulation and acceptance of experience, being aware of the current experience as it is without evaluating the experience as positive or negative. Much research has evaluated the attention regulation component and found that MP improves high-level (effortful) attention with few reported effects on low-level (automatic) attention. It is unclear whether MP affects merely low- or high-level attention, or both, because little empirical research has examined both low- …

Influences Of Reasoning And Achievement Motivation On Complex Problem Solving In A New Microworld Operationalization, Stephan Bartholdy, Ulrike Kipman

Journal of Global Education and Research

Complex Problem Solving (CPS) can be defined as those psychological processes that enable a person to achieve goals under complex conditions, which are characterized by their complexity, connectivity, dynamics, lack of transparency, and polytely. Although many hypothesized influences have previously been tested concerning their relevance for the process of solving complex problems (e.g., general intelligence), results were often found to be rather heterogeneous. As this was found to be partially caused by fundamental differences between measurements of CPS, a new operationalization was used in the present study: Following the Microworld approach, CPS was assessed in the simulation game Cities: Skylines …

Decisions, Decisions: Review Of Mindware: Tools For Smart Thinking By Richard E. Nisbett, Anne Kelly

Numeracy

Richard Nisbett. 2015. Mindware: Tools for Smart Thinking. (New York, NY: Farrar, Strauss, and Giroux). 336 pp. ISBN: 9780374536244.

Social psychologist Richard E. Nisbett provides help in identifying and overcoming faulty cognitive strategies and replacing them with more accurate heuristics. To do so, Nisbett draws from statistics, correlation, experiments, differences in Western and Eastern thought, and, especially, social influence.

Conditions For Maximizing Expected Value In Repeated Choices From Experience, Andrea Y. Ranieri

USF Tampa Graduate Theses and Dissertations

It is largely expected that people can learn from past experiences and use this knowledge to make better decisions in the future. However, there are aspects inherent in experiential learning which may affect the extent to which people can extract and use information from experiential feedback to make advantageous decisions. Three aspects inherent in experiential learning were identified: (1) it is reliant on memory, (2) information is gathered exclusively through outcome feedback, and (3) outcome feedback is inherently dynamic. The current investigation explored how each of these aspects may help shape experiential decision making, and examined how the presence of …

Mapping Reward Values To Cues, Locations, And Objects: The Influence Of Reward Associations On Visual Attention, Constanza De Dios

USF Tampa Graduate Theses and Dissertations

Previous work has attempted to fit reward-driven attentional selection as being exogenous (stimulus-driven) or endogenous (goal-driven). However, recent work suggests that reward’s effects on attention depend on the type of stimulus feature that the motivational information is imparted during learning (incentive salience). If true, then reward should not be limited to solely impacting early perceptual or late categorization processes attention. The current study used event-related potentials (ERPs) to test the idea that reward’s effects on attention depend on the process that the reward information is embedded – early perceptual or late categorization. Results demonstrated reward-driven effects on perceptual representation when …

Home-Based Cognitive Monitoring: The Role Of Personality And Predictors Of Adherence And Satisfaction, Nasreen A. Sadeq

USF Tampa Graduate Theses and Dissertations

Over the last several decades, a growing awareness of the benefits of regular screening for common health conditions, such as cancer and cardiovascular diseases, has paved the way for preventative screenings to become routine in medical settings. Given that cognitive impairment is frequently reported as the number one worry of older adults, home-based cognitive monitoring may be an innovative solution that allows middle aged and older adults to take an active role in monitoring an important aspect of their health. Although several home-based cognitive monitoring programs have been validated for use in clinical and home-based settings, the Cogstate Brief Battery …

Neuro-Correlates Of Word Processing Among Four-And-Five-Year-Old Children From Homes Varying In Socio-Economic Status, Wendy Olsen

USF Tampa Graduate Theses and Dissertations

A large body of research relates families’ socioeconomic status (SES) to child language development (Hoff & Tian, 2005). Results from these studies indicate preschoolers from low SES backgrounds may have underdeveloped linguistic foundations required for future academic success (Sirin, 2005; Lacouri & Tissington, 2011). These differences have been said to create a 30 million word-gap between the language experiences of low and middle to high SES children by the age of 3 years. Thus, children who come from lower SES backgrounds often lack the vocabulary knowledge used in school and in textbooks (Hart & Risley, 1995). One index of SES …

Lexical Influence In Phoneme Perception With Non-Degraded And Spectrally-Degraded Speech, Jane Bradley Smart

USF Tampa Graduate Theses and Dissertations

In speech perception tasks with ambiguous bottom-up information, lexical processes have been shown to influence listener responses, such as in phoneme categorization tasks (Ganong, 1980). Proponents of interactive theories of speech perception and spoken word recognition assert this influence is a top-down feedback mechanism that can affect bottom-up perceptual processes (e.g., McClelland & Elman, 1986). While robust influences on phoneme perception have been reported in multiple studies (Connine & Clifton, 1987; Ganong, 1980; Gow, Segawa, Ahlfors, & Lin, 2008; Pitt & Samuel, 1993; among others), some phonetic contrasts, particularly those that distinguish place of articulation, have been tested in very …

Evaluating Theories Of Bilingual Language Control Using Computational Models, Mark D. Lowry

USF Tampa Graduate Theses and Dissertations

Bilingual language control refers to how bilinguals are able to speak exclusively in one language without the unintended language intruding. Two prominent verbal theories of bilingual language control have been proposed by researchers: the inhibitory control model (ICM) and the lexical selection mechanism model (LSM). The ICM posits that domain-general inhibition is employed in order to suppress the unintended language’s activation. The LSM posits that inhibition is not used; rather a lexical selection mechanism targets only the intended language’s words. In order to better test the theories’ hypotheses, I developed computational models to estimate participants’ reaction times when naming in …

Phishing In Dark Waters: A Quasi-Experimental Approach With Evaluating Cyber-Security Training For End-Users, Jaclyn Martin

USF Tampa Graduate Theses and Dissertations

With the increasing amount of digital storage of personal and organizational data, there has been an increasing number of cyber-attacks, which has spurred much research on how to reduce phishing susceptibility. However, there are several gaps in the current research. There is little research on the effectiveness of different interventions on phishing susceptibility. There is no research on the differential impact of interventions on sensitivity (ability to detect phishing emails) and response bias (propensity to treat emails as threatening) or the influence of individual characteristics on phishing email training success. This study addresses these gaps using a quasi-experimental approach to …

Reference Dependence In Bayesian Reasoning, Alaina N. Talboy

USF Tampa Graduate Theses and Dissertations

The purpose of this dissertation is to examine aspects of the representational and computational influences on Bayesian reasoning as they relate to reference dependence. Across three studies, I explored how dependence on the initial problem structure influences the ability to solve Bayesian reasoning tasks. Congruence between the problem and question of interest, response errors, and individual differences in numerical abilities was assessed. The most consistent and surprising finding in all three experiments was that people were much more likely to utilize the superordinate value as part of their solution rather than the anticipated reference class values. This resulted in a …

Going To School In The Forest: Changing Evaluations Of Animal-Plant Interactions In The Kichwa Amazon, Jeffrey T. Shenton

Journal of Ecological Anthropology

For rural, indigenous communities the ways structural modernization, exposure to Western-scientific epistemologies, and formal schooling affect environmental reasoning remain unclear. For one Kichwa community in the Napo region of Ecuador, daily routines have re-oriented toward formal schooling but environmental learning opportunities remain intact. Here, while a Species Interaction Task elicited consensus across ages on inferred ecological interactions, younger people reasoned differently than older people: for them, animal interactions with flora were considered damaging, not neutral. Aspirational practices like schooling can thus reorient environmental reasoning, even in contexts in which young people share cultural understandings of local ecological relationships with adults.

Numeracy And Social Justice: A Wide, Deep, And Longstanding Intersection, Kira Hamman, Victor Piercey, Samuel L. Tunstall

Numeracy

We discuss the connection between the numeracy and social justice movements both in historical context and in its modern incarnation. The intersection between numeracy and social justice encompasses a wide variety of disciplines and quantitative topics, but within that variety there are important commonalities. We examine the importance of sound quantitative measures for understanding social issues and the necessity of interdisciplinary collaboration in this work. Particular reference is made to the papers in the first part of the Numeracy special collection on social justice, which appear in this issue.

Anticipatory Motivation For Drinking Alcohol: An In-Vivo Study, Bryan Benitez

USF Tampa Graduate Theses and Dissertations

Numerous studies from various research groups have already shown the usefulness of alcohol expectancies as predictors of long-term future alcohol consumption. The present study extends this line of research by directly testing whether alcohol expectancies measured in the moment using free association are useful as predictors of alcohol consumption in the next few hours. An ecological momentary assessment (EMA) procedure was used to examine how alcohol expectancies might fluctuate during days in which many people expect to drink (e.g. Fridays, Saturdays) and how these fluctuations in alcohol expectancies might predict future drinking and/or co-vary with important contextual variables during that …

Improving Intervention Decisions To Prevent Genocide: Less Muddle, More Structure, Robin Gregory, Michael Harstone, Paul Slovic

Genocide Studies and Prevention: An International Journal

Decisions to intervene in a foreign country to prevent genocide and mass atrocities are among the most challenging and controversial choices facing national leaders. Drawing on techniques from decision analysis, psychology, and negotiation analysis, we propose a structured approach to these difficult choices that can provide policy makers with additional insight, consistency, efficiency, and defensibility. We propose the use of a values-based framework to clarify the key elements of these complex choices and to provide a consistent structure for comparison of the likely benefits, risks, and tradeoffs associated with alternative intervention strategies. Results from a workshop involving Ambassadors and experienced …

Contributions Of Appetitive And Aversive Motivational Systems To Decision-Making, Heather E. Soder

USF Tampa Graduate Theses and Dissertations

Optimal decision-making entails outcome evaluation, comparing received costs and benefits with predicted costs and benefits. The anterior cingulate cortex (ACC), a brain area with major connections to the appetitive and aversive motivation systems, may provide the neural substrate of this evaluation process. One way to measure the relative contribution of these systems on decision-making is to measure individual differences in risk-taking behaviors. For individuals who make risky choices, this evaluation step may be biased: some show a preference for immediate, short-term rewards (increased appetitive system), while devaluing the long-term consequences of their choices (decreased aversive system). However, most studies supporting …

Learning To Think Slower: Review Of Thinking, Fast And Slow By Daniel Kahneman (2011), Samuel L. Tunstall, Patrick N. Beymer

Numeracy

Daniel Kahneman. Thinking, Fast and Slow (New York, NY: Farrar, Straus and Giroux) 499 pp. ISBN 978-0374275631.

As an expansive review of Kahneman and others' work over the past half-century in understanding human decision-making, Thinking, Fast and Slow provides Numeracy readers much to consider for both pedagogy and research. In this review, we outline Kahneman's core argument—that humans use both rash (emotional) System 1 thinking and slow (logical) System 2 thinking—then discuss how such systems might be addressed in a quantitative literacy classroom.

Think Twice: Review Of Thinking, Fast And Slow By Daniel Kahneman (2011), Anne Kelly

Numeracy

Daniel Kahneman. Thinking, Fast and Slow (New York, NY: Farrar, Straus and Giroux) 499 pp. ISBN 978-0374275631.

In Thinking, Fast and Slow, Nobel Prize-winning psychologist Daniel Kahneman significantly sharpens our understanding of human decision-making and the systems of thinking that underlie it. He offers a compelling critique of the rational-agent model, arguing that, while we can and do use reason, we often fall back on a type of thinking that operates quickly and requires less cognitive effort but is vulnerable to faulty belief.
