Conditions For Maximizing Expected Value In Repeated Choices From Experience, Andrea Y. Ranieri Jul 2019

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 Jul 2019

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 Jul 2019

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 Jun 2019

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 Apr 2019

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 Apr 2019

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 Mar 2019

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 Mar 2019

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 …
