Improving Measurements Of Similarity Judgments With Machine-Learning Algorithms, Jeffrey R. Stevens, Alexis Polzkill Saltzman, Tanner Rasmussen, Leen-Kiat Soh Jan 2021

Improving Measurements Of Similarity Judgments With Machine-Learning Algorithms, Jeffrey R. Stevens, Alexis Polzkill Saltzman, Tanner Rasmussen, Leen-Kiat Soh

Jeffrey Stevens Publications

Intertemporal choices involve assessing options with different reward amounts available at different time delays. The similarity approach to intertemporal choice focuses on judging how similar amounts and delays are. Yet we do not fully understand the cognitive process of how these judgments are made. Here, we use machine-learning algorithms to predict similarity judgments to (1) investigate which algorithms best predict these judgments, (2) assess which predictors are most useful in predicting participants’ judgments, and (3) determine the minimum number of judgments required to accurately predict future judgments. We applied eight algorithms to similarity judgments for reward amount and time delay …


Exercise Shifts Hypothetical Food Choices Toward Greater Amounts And More Immediate Consumption, Karsten Koehler, Safiya E. Beckford, Elise Thayer, Alexandra R. Martin, Julie B. Boron, Jeffrey R. Stevens Jan 2021

Exercise Shifts Hypothetical Food Choices Toward Greater Amounts And More Immediate Consumption, Karsten Koehler, Safiya E. Beckford, Elise Thayer, Alexandra R. Martin, Julie B. Boron, Jeffrey R. Stevens

Jeffrey Stevens Publications

Although exercise modulates appetite regulation and food intake, it remains poorly understood how exercise impacts decision-making about food. The purpose of the present study was to assess the impact of an acute exercise bout on hypothetical choices related to the amount and timing of food intake. Forty-one healthy participants (22.0 ± 2.6 years; 23.7 ± 2.5 kg/m 2 , 56% female) completed 45 min of aerobic exercise and a resting control condition in randomized order. Food amount preferences and intertemporal food preferences (preference for immediate vs. delayed consumption) were assessed using electronic questionnaires with visual food cues. Compared to rest, …

Our studies show that elephants do vary significantly between individuals in both exploration and neophobia.


Measuring Intelligence With The Sandia Matrices: Psychometric Review And Recommendations For Free Raven-Like Item Sets, Alexandra M. Harris, Jeremiah T. Mcmillan, Benjamin Listyg, Laura E. Matzen, Nathan Carter Dec 2020

Measuring Intelligence With The Sandia Matrices: Psychometric Review And Recommendations For Free Raven-Like Item Sets, Alexandra M. Harris, Jeremiah T. Mcmillan, Benjamin Listyg, Laura E. Matzen, Nathan Carter

Personnel Assessment and Decisions

The Sandia Matrices are a free alternative to the Raven’s Progressive Matrices (RPMs). This study offers a psychometric review of Sandia Matrices items focused on two of the most commonly investigated issues regarding the RPMs: (a) dimensionality and (b) sex differences. Model-data fit of three alternative factor structures are compared using confirmatory multidimensional item response theory (IRT) analyses, and measurement equivalence analyses are conducted to evaluate potential sex bias. Although results are somewhat inconclusive regarding factor structure, results do not show evidence of bias or mean differences by sex. Finally, although the Sandia Matrices software can generate infinite items, editing …


Difficult Turned Easy: Suggestion Renders A Challenging Visual Task Simple, Mathieu Landry, Jason Da Silva Castanheira, Jérôme Sackur, Amir Raz Dec 2020

Difficult Turned Easy: Suggestion Renders A Challenging Visual Task Simple, Mathieu Landry, Jason Da Silva Castanheira, Jérôme Sackur, Amir Raz

Psychology Faculty Articles and Research

Suggestions can cause some individuals to miss or disregard existing visual stimuli, but can they infuse sensory input with nonexistent information? Although several prominent theories of hypnotic suggestion propose that mental imagery can change our perceptual experience, data to support this stance remain sparse. The present study addressed this lacuna, showing how suggesting the presence of physically absent, yet critical, visual information transforms an otherwise difficult task into an easy one. Here, we show how adult participants who are highly susceptible to hypnotic suggestion successfully hallucinated visual occluders on top of moving objects. Our findings support the idea that, at …


Cuban Immigrants’ Experience With Acculturation And How They Cope In The United States, Lourdes Araujo Dec 2020

Cuban Immigrants’ Experience With Acculturation And How They Cope In The United States, Lourdes Araujo

Dissertations

Objective: This research examines how Cuban immigrants experience cope and adapt to the United States. Cuban immigration is associated with specific stressors related to the immigration experience and the necessary process of acculturation and assimilation. These major stressors can result in mental health concerns among Cuban immigrants; however, no studies have examined how acculturation may influence Cuban immigrants’ coping skills and resultant mental health concerns. This unique study is the first to examine the coping skills Cuban immigrants use during acculturation and the effects of these skills on Cuban immigrants’ mental health. Methods: Seventeen participants completed a semistructured interview and …


Response To Commentaries On ‘Hard Criteria For Empirical Theories Of Consciousness’, Adrian Doerig, Aaron Schurger, Michael H. Herzog Nov 2020

Response To Commentaries On ‘Hard Criteria For Empirical Theories Of Consciousness’, Adrian Doerig, Aaron Schurger, Michael H. Herzog

Psychology Faculty Articles and Research

In consciousness research, we have a very large number of theories, which exceeds by far the number of theories in other fields. We recently presented a set of criteria for evaluating and comparing theories of consciousness, and then applied the criteria to a number of different theories. Our publication sparked strong responses as evident by the many comments published in Cognitive Neuroscience (this issue). Overall, there seems to be consensus that a theory of consciousness (ToC) needs to have an unconscious alternative, but other criteria sparked controversy. The hottest debate is to what extent consciousness needs to work with purely …


Historical Trauma Response Scores As A Function Of Unresolved Grief And Substance Use Disorder In American Indian Populations, Andrew R. Saunders Nov 2020

Historical Trauma Response Scores As A Function Of Unresolved Grief And Substance Use Disorder In American Indian Populations, Andrew R. Saunders

Undergraduate Research Symposium

Abstract

Researchers are interested in the outcomes of interventions, specifically, measuring historical trauma (HT) among American Indian/Alaska Native communities and the long-term distress and substance abuse as a result of historical trauma response (HTR). Previous literature has implicated limitations in the clinical conceptualization of the relationship between intergenerational transfer of HTR and substance abuse. The aim of the current study is to examine treatment efficacy of 50 homosexual, American Indian males randomized to a culturally-adapted juxtaposition of (1) Group Interpersonal Psychotherapy (IPT), (2) Cognitive Processing Therapy (CPT), and (3) Historical Trauma and Unresolved Grief Intervention (HTUG), or (4) waitlisted on …

China’S “Three Warfares”: People’S Liberation Army Influence Operations, Edwin S. Cochran, U.S. Department Of Defense, Retired Sep 2020

China’S “Three Warfares”: People’S Liberation Army Influence Operations, Edwin S. Cochran, U.S. Department Of Defense, Retired

International Bulletin of Political Psychology

The following article—whose author is both a retired US Army officer and retired Department of Defense civilian employee with multiple publications—focuses on Chinese information operations. Readers might wish to speculate on matters such as why the Chinese have organized the way they have, whether the organization leads to optimal integration of tools of national security/political power, and how vulnerable specific populations and even intelligence cultures are to specific types of information operations. One might even conclude that the only thing that has not changed in thousands of years has been the technology available to influence others.

This article examines the …

The Effects Of Self-Esteem And Motivation On Cognitive Control, Andrea Benavides Jun 2020

The Effects Of Self-Esteem And Motivation On Cognitive Control, Andrea Benavides

Dissertations, Theses, and Capstone Projects

Cognitive control describes a set of mechanisms that guide behavior towards a goal (Cohen, 2017). The successful execution of cognitive control is essential for effective learning, information processing, problem solving, and academic achievement (Visu-Petra et al., 2011). The Expected Value of Control framework (EVC; Shenhav et al., 2013) suggests that control carries an inherent cost, which is weighed against the potential benefits of expending it. This cost-benefit analysis determines the direction and intensity that a goal is pursued. Importantly, motivation plays a role in this cost-benefit analysis and may function as the factor that offsets the cost of control expenditure …


Presence And Degree Of Contrafreeloading In African Grey Parrots (Psittacus Erithacus), Gabriella E. Smith May 2020

Presence And Degree Of Contrafreeloading In African Grey Parrots (Psittacus Erithacus), Gabriella E. Smith

Theses and Dissertations

This study examined contrafreeloading—choosing a physical task to access food over free food—in two Grey parrots (Psittacus erithacus). Both birds contrafreeloaded for food of equal or higher value, but differed in which contrafreeloading task they preferred. Differences between the parrots are considered as individual preferences for self-reinforcing tasks.


The Academic Success And Beyond-Academic Wellbeing Of High Functioning Autistic Boys: A Policy-Professional Care-School-Parent Ecological Perspective, Evelyn Sauceda May 2020

The Academic Success And Beyond-Academic Wellbeing Of High Functioning Autistic Boys: A Policy-Professional Care-School-Parent Ecological Perspective, Evelyn Sauceda

Electronic Theses and Dissertations

High Functioning Autistic (HFA) boys have significant social, emotional, and cognitive difficulties and unique cognitive abilities that require special support from stakeholders in their ecology (policy makers, care providers, schools, and parents). The quality of such support and its ecological integration are of poor quality. The purpose of this study was to report on the perceptions of parents of HFA boys about their children’s academic and beyond-academic experiences as understood within a policy-care provider-school-parent ecological framework. This study contributes to the limited ecological literature on the topic. This exploratory, qualitative, phenomenological, non-experimental, and cross-sectional research study used a non-probability, purposive, …


Off-Topic Verbosity And Sustained Attention Among Young Adult And Older Adult Age Cohorts, Jessica H. Helphrey May 2020

Off-Topic Verbosity And Sustained Attention Among Young Adult And Older Adult Age Cohorts, Jessica H. Helphrey

Psychology and Counseling Theses

Off-topic verbosity (OTV) is tangential discourse with excessive and irrelevant information. Older adults have been historically labeled as having high OTV, and research has suggested that high OTV in older adults may be linked with cognitive decline. While past studies have utilized brief cognitive measures to further expound upon the links between cognition and OTV, studies have lacked consistency and lengthy measures. This study sought to elucidate the relationship between OTV and cognition in both older adult and young adult age cohorts utilizing a sustained attention measure. Young adults (n = 61; age range: 18-28, M = 20.57, SD = …

Searching For Neural Mechanisms Of Social Cognition, Chandler Siemonsma, Cristina Uribe, Louanne Boyd, Aaron Schurger, Deanna Hughes, Tian Lan

Student Scholar Symposium Abstracts and Posters

Social cognition involves the integration and pruning of perceptual information which leads to the formation of an abstract representation, which is also known as the perceptual gist. This study examined 87 differences in visual perception of Mooney face stimuli of differing sizes and the relationship to gist formation in ten individuals with autism compared to neurotypical controls. Parents of both groups completed the Social Responsiveness Scale (SRS-2) to assess social functioning in real-world scenarios.

Positive Emotions And Favorable Cardiovascular Health: A 20-Year Longitudinal Study, Julia K. Boehm, Ying Chen, Farah Qureshi, Jackie Soo, Peter Umokoro, Rosalba Hernandez, Donald Lloyd-Jones, Laura D. Kubzansky

Psychology Faculty Articles and Research

No studies have examined whether positive emotions lead to favorable cardiovascular health (CVH) early in the lifespan, before cardiovascular disease is diagnosed. Moreover, the direction of the association has not been thoroughly investigated. Among younger adults, we investigated whether baseline positive emotions were associated with better CVH over 20 years. We also considered whether baseline CVH was associated with subsequent positive emotions during the same period.

Participants included 4196 Black and White men and women from the Coronary Artery Risk Development in Young Adults Study. Positive emotions and cardiovascular-related parameters were each assessed in 1990 (this study's baseline), with repeated …

Psychology Faculty Articles and Research

The Project Talent Twin and Sibling (PTTS) study includes 4481 multiples and their 522 nontwin siblings from 2233 families. The sample was drawn from Project Talent, a U.S. national longitudinal study of 377,000 individuals born 1942–1946, first assessed in 1960 and representative of U.S. students in secondary school (Grades 9–12). In addition to the twins and triplets, the 1960 dataset includes 84,000 siblings from 40,000 other families. This design is both genetically informative and unique in facilitating separation of the ‘common’ environment into three sources of variation: shared by all siblings within a family, specific to twin-pairs, and associated with …


Smartphones, Stress, And The Reduction Of Cognitive Resources, Jenay R. Stone Jan 2020

Smartphones, Stress, And The Reduction Of Cognitive Resources, Jenay R. Stone

College of Graduate Studies: Theses & Dissertations

Smartphones are a ubiquitous part of daily life for most Americans. They offer an abundance of information, connectivity, and entertainment. Previous research suggests that smartphones are also responsible for cognitive costs in educational, public, private and professional settings when in use or audibly creating stimuli in the environment. Smartphones are also linked to an automatic attenuation of cognitive resources even when not in use and merely salient (Ward, Duke, Gneezy and Bos; Journal of the Association for Consumer Research; 2, 141, 154, 2017). The purpose of the present study was to experimentally test the effect of cell phone salience …


Exploratory Learning Activities In The Physics Classroom: Contrasting Cases Versus A Rich Dataset., Campbell Rightmyer Bego Dec 2019

Exploratory Learning Activities In The Physics Classroom: Contrasting Cases Versus A Rich Dataset., Campbell Rightmyer Bego

Electronic Theses and Dissertations

In exploratory learning, students engage in an exploration activity on a new topic prior to instruction. This inversion of the traditional tell-then-practice order has been shown to benefit learning outcomes, especially conceptual knowledge and preparation for future learning, but not always. In three studies, the current work examines whether the type of exploration activity impacts learning mechanisms and outcomes, on the topic of gravitational field in undergraduate physics classrooms. Activities using either contrasting cases (CC) or a rich dataset (RD) are compared in two instructional orders, explore-first (EF) and instruct-first (IF). Learning outcomes measured procedural knowledge, conceptual knowledge, and performance …

Humor Improves Women’S But Impairs Men’S Iowa Gambling Task Performance, Jorge Flores‑Torres, Lydia Gómez‑Pérez, Kateri Mcrae, Vladimir López, Ivan Rubio, Eugenio Rodriguez Nov 2019

Humor Improves Women’S But Impairs Men’S Iowa Gambling Task Performance, Jorge Flores‑Torres, Lydia Gómez‑Pérez, Kateri Mcrae, Vladimir López, Ivan Rubio, Eugenio Rodriguez

Psychology: Faculty Scholarship

The Iowa Gambling Task (IGT) is a popular method for examining real-life decision-making. Research has shown gender related differences in performance, in that men consistently outperform women. It has been suggested that these performance differences are related to decreased emotional control in women compared to men. Given the likely role of emotion in these gender differences, in the present study, we examine the effect of a humor induction on IGT performance and whether the effect of humor is moderated by gender. IGT performance and parameters from the Expectancy Valence Model (EVM) were measured in 68 university students (34 men; mean …


Self-Concept Clarity And The Bodily Self: Malleability Across Modalities, Sonia A. Krol, Rémi Thériault, Jay A. Olson, Amir Raz, Jennifer A. Bartz Oct 2019

Self-Concept Clarity And The Bodily Self: Malleability Across Modalities, Sonia A. Krol, Rémi Thériault, Jay A. Olson, Amir Raz, Jennifer A. Bartz

Psychology Faculty Articles and Research

The self has fascinated scholars for centuries. Although theory suggests that the self-concept (cognitive self-understanding) and bodily self (pre-reflective awareness of one’s body) are related, little work has examined this notion. To this end, in Study 1, participants reported on self-concept clarity (SCC) and completed the rubber hand illusion (RHI), a paradigm in which synchronous (vs. asynchronous) stimulation between a prosthetic hand and one’s own hand leads one to “embody” the prosthetic hand. Whereas participants were equally susceptible to the RHI during synchronous stroking, low-SCC individuals were more vulnerable to the illusion during asynchronous stroking, when the effect is unwarranted. …

The Influence Of Tropical Climate On Cognitive Task Performance And Aiming Accuracy In Young International Fencers, Nicolas Robin, Aurelie Collado, Stephane Sinnapah, Elisabeth Rosnet, Olivier Hue, Guillaume R. Coudevylle

Journal of Human Performance in Extreme Environments

This study examined how a tropical climate (TC) influences the cognitive and aiming task performances of young international fencers. The participants performed the tasks in TC and an air-conditioned room. In each session, they completed questionnaires evaluating affective states, fatigue, and comfort and thermal sensations. They also carried out cognitive tasks (simple and choice reaction time, attention, and vigilance tasks) and a motor task testing aiming accuracy with a sword while wearing protective clothing and a mask. TC, which was observed to decrease thermal discomfort, was revealed to decrease aiming accuracy and positive affective states. There was no deleterious effect …


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 …
