Conflicting Social Information And Its Impact On Sentence Comprehension In Young Adults With Dld: An Eye Tracking Study, Ansley Davis

USF Tampa Graduate Theses and Dissertations

Individuals must recognize linguistic and non-linguistic social cues to resolve contextual ambiguities in their conversations. When the linguistic and social cues match, sentence processing is facilitated. However, conflicts between linguistic and social stimuli (i.e., incongruency) can lead to prediction errors which slow sentence processing. Limited research has explored the social cognition conflict resolution skills in individuals with Developmental Language Disorder (DLD) despite their documented emotion processing deficits. This study considers the role of social prediction processing in adults with DLD as they engage in a social cognition conflict resolution task.

Young adults with DLD (n=29) and typically developing (TD) peers …

Creative Climates: The Impact Of Different Environmental Exposure On Group And Individual Creativity, Michael P. Hopkins

USF Tampa Graduate Theses and Dissertations

This thesis examined the influence of indoor versus outdoor environmental exposure and individual versus group participation on verbal creativity performance. Guided primarily by Attention Restoration Theory (ART; Kaplan & Kaplan, 1989), it was predicted that outdoor natural settings would enhance creativity through restorative cognitive processes. Additionally, it was hypothesized that groups would outperform individuals due to the cognitive advantages of collective induction and information pooling. Participants (N = 256) completed verbal creativity tasks—Remote Associates Task (RAT; convergent creativity) and Alternate Uses Task (AUT; divergent creativity)—following a 30-minute exposure period in either an indoor student center or outdoor botanical garden setting, …

The Ensemble Code As A Constructed Working Memory, Jacob Zepp

USF Tampa Graduate Theses and Dissertations

This dissertation formalizes and refines a new theory of ensemble coding: the Non-Selective Transfer Model. Within this theory, ensemble codes and subsequent summary judgments are the result of representations constructed over a subset of information that is encoded into working memory. The work begins with a brief review of current ideas present within the ensemble coding literature, followed by a set of formalized descriptions of ensemble coding theories that have been proposed. A discussion of relevant theories present in the working memory literature is also provided to motivate the structure of the subsequent model. The Non-Selective Transfer Model 2 is …

Is It Really An Affect Gap? Outcome Type Vs. Intensity In Risky Decision-Making, Jordan E. Martin

USF Tampa Graduate Theses and Dissertations

People respond to decisions differently when emotion is involved. The affect gap hypothesissuggests that people are more likely to focus on the outcome and ignore probabilities of outcomes when emotions are strong, and people are likely to include consideration of probabilities with outcomes when emotions are weak. However, typical methodologies have a confound in the manipulation of affect, with affect-poor outcomes that are quantitative in nature (e.g., money) and affect-rich outcomes that are typically qualitative (e.g., experiences). To address this confound, I created a mixed factorial design to examine choices made in lottery pairs manipulated by intensity (low, high), outcome …

On The Role Of Prediction In Streaming Hierarchical Learning, Ramy Mounir

USF Tampa Graduate Theses and Dissertations

In today's world, AI systems need to make sense of large amounts of data as it unfolds in real-time, whether it's a video from surveillance and monitoring cameras, streams of egocentric footage, or sequences in other domains such as text or audio. The ability to break these continuous data streams into meaningful events, discover nested structures, and predict what might happen next at different levels of abstraction is crucial for applications ranging from passive surveillance systems to sensory-motor autonomous learning. However, most existing models rely heavily on large, annotated datasets with fixed data distributions and offline epoch-based training, which makes …

Cues And Identity: Assessing Substance Use Cues, Life Experience, And Context, Katelynn Carlsen

USF Tampa Graduate Theses and Dissertations

This project employs Ecological Momentary Assessment (EMA) methods alongside semi-structured interviews to examine substance use cues, or “triggers”, in the everyday context. This includes repeated assessment of participants’ behaviors and thoughts over time. EMA allows researchers to sample phenomena the moment they occur within the context. These methods are most used in psychology and clinical science. Current research on substance use relies on lab-based assessments to understand cues and their relationship to consumption (Carter and Tiffany 1999, Conklin and Tiffany 2003, Witteman et al. 2015). This analysis uses data collected by the Cues in the Everyday (CITED) Team. The CITED …

The Effect Of Emotion On Risk Perception And The Blackstone Ratio, Brianna Duncan

USF Tampa Graduate Theses and Dissertations

In the public debate concerning crime, there are generally two opposing positions regarding error rates within guilt convictions: a greater concern for false positives (convicting an innocent person) or a greater concern for false negatives (not convicting a guilty person). Public attitudes have typically indicated that false positives should be considered worse, with a range in global surveys from 51% (Zhuo, 2021) to as high as 85% (Scurich, 2015) of the population expressing this perspective. To explore the reason behind these beliefs, the current study explores the effect of emotions. Lerner and Keltner (2000) found that fear and anger, though …

The Local Neurologies Of Substance Use Triggers, Breanne I. Casper

USF Tampa Graduate Theses and Dissertations

Substance use triggers are largely understood to be embedded in drug use contexts and to be a major precipitator of relapse. Yet, the relationship between triggers and future instances of drug use is not quite clear– particularly in understanding the nuances of when triggers are “triggering” and when they are not. Additionally, there is little ethnographic work that explores how individuals interact with triggers in contexts related to substance use, particularly during periods of active use. This project employs ethnographic and survey research methods to interrogate substance use triggers in the harm reduction context. In doing so, it answers the …

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 …

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 …

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/ …

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- …

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 …

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 …

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 …

Emotional Memory For Affective Words In Manifest And Prodromal Huntington’S Disease, Patricia Lynn Johnson

USF Tampa Graduate Theses and Dissertations

Huntington’s disease (HD) patients have been found to have specific deficits in emotional processing, most consistently demonstrating impairment recognizing the emotion expressed on a static face. The purpose of this study was to examine emotional memory in HD, which has not yet been investigated, and its relationship with executive functioning, emotional facial recognition, and the disease progression in HD. An emotional memory task with pleasant, neural, and unpleasant words was administered to control (n=26), prodromal HD (n=26), and manifest HD (n=29) participants in addition to executive function measures, an apathy scale, and emotional facial recognition task. Free recall was not …

Can We Talk?: Synergistic Effects Of Cognitive And Behavioral Frameworks To Address Substance Use And Abuse, Lauren Jaye Adams

USF Tampa Graduate Theses and Dissertations

Behavioral economic accounts of substance use have provided a novel framework to examine constraints that affect behaviorally driven outcomes. Several behavioral studies support the application of such frameworks to examine impulsive decision-making processes as well as how subjective reward influences substance use. Based on stimulus-response models, behavioral economic research often applies mathematical formulas to draw conclusions about behavioral outcomes. These mathematical formulas, while useful, largely ignore decades of cognitive psychology research that have examined state-based influences (e.g., mood, environment, motivational processes, etc.) on behavioral sequelae. To address this issue, the present study merged a cognitive framework into two behavioral economic …

Moderation Analysis Of Bowel Function Among Nutrients And Physical Function Or Depression, As Well As Whether Bowel Function Is Related To Cognition In Older Adults, Jessie Alwerdt

USF Tampa Graduate Theses and Dissertations

As we age, the risk for gut issues, such as smooth muscle tone, may be an underlying indirect or direct cause or risk factor for many age-related issues, such as frailty. Consequences of decreased motility and depleted epithelial barrier may result in nutrient deficiencies that may increase the risk for malnutrition (Brownie, 2006). Further, there is increasing evidence that there is a gut-brain-axis relationship that may influence cognition and mental health issues, such as depression and anxiety. While there are relationships established, the interconnections of these factors have yet to be fully understood.

This dissertation examined several relationships specific to …

Attentional Window And Global/Local Processing, Steven Peter Schultz

USF Tampa Graduate Theses and Dissertations

How does the focus of attention influence the encoding of information? Research has shown that size and allocation of the attentional window has an influence on what information is attended to or missed. The size-scale of features also effects processing of visual information. Previous research involving hierarchical stimuli suggests precedence for global features. In the present experiment, I investigated the influence of attentional window size on accuracy of encoding hierarchical stimuli at the global and local level. Here I introduce a new method for manipulating the size of the attentional window and for collecting unconstrained responses. At the start of …

The Effects Of Cognitive Training Among Individuals With Neurodegenerative Diseases, Elise Gabriela Valdes

USF Tampa Graduate Theses and Dissertations

With the growing older adult population, neurodegenerative diseases common in old age such as mild cognitive impairment (MCI) or Parkinson’s disease (PD) are becoming increasingly germane areas of research. Pharmacological treatments have thus far been unsuccessful in treating cognitive decline associated with these neurodegenerative disorders. Alternative interventions, such as cognitive training programs, have shown promise. The current dissertation contains three papers examining cognitive interventions in neurodegenerative diseases. The first paper examined the longitudinal effects of cognitive speed of processing training (SPT) among those with PD. Results showed that training gains seen at initial post-test were maintained three months later. The …

Motivation For Mathematics: The Development And Initial Validation Of An Abbreviated Instrument, Kenneth Lee Butler

USF Tampa Graduate Theses and Dissertations

This study outlines the development and initial validation of an abbreviated instrument intended to measure motivation for mathematics of university students in developmental algebra courses. I look across many of the predominant theories on motivation with the aim of representing several of these theories as latent constructs in a single instrument that is short enough to be administered in a reasonable amount of time, but inclusive enough that it could incorporate subscales representing multiple distinct latent factors. This study answers a call by researchers expressing a need to investigate relationships between disparate theories on motivation and is a response to …
