Does Perceived Angular Declination Contribute To Perceived Optical Slant On Level Ground?, Z. Li, Frank H. Durgin

Psychology Faculty Works

When one looks at a spot on level ground, the local optical slant (i.e., surface orientation relative to the line of sight) is geometrically equivalent to the angular declination (i.e., sagittal visual direction relative to horizontal). In theory, angular declination provides an unbiased proximal source of information for estimating optical slant on level ground. Two experiments were conducted to investigate whether human visual systems take advantage of this information. An aspect ratio task was used as an implicit measure for assessing perceived optical slant. Participants gave verbal estimates of the perceived aspect ratio of an L-shaped arrangement, formed by three …

Entropy As A Method For Identifying Treatment Resistant Autism Spectrum Disorder, Nathan Wright

Doctoral Dissertations

Background: Individuals diagnosed with Autism Spectrum Disorder (ASD) experience lifelong challenges which can impact peer relationships, adaptive functioning, and independent living. Verbal intelligence has proven to be the strongest indicator of outcomes and responsiveness to behavioral intervention, but this property only stabilizes in children between 6 and 8 years of age. Behavioral treatment is the primary intervention for individuals diagnosed with ASD, but it is most effective when delivered as an early intervention strategy for toddlers and very young children. A biomarker which could distinguish treatment resistant subgroups of ASD from would allow for the development and implementation of alternative …

Architecture Of Aggression In Cyberspace. Testing Cyber Aggression In Young Adults In Hungary, Katalin Parti, Tibor Kiss, Gergely Koplányi

International Journal of Cybersecurity Intelligence & Cybercrime

In order to test whether and how violence is exacerbated in online social networking sites, we utilized the BryantSmith Aggression Scale (Bryant & Smith, 2001), and included examples in the questionnaire offering solutions for 7 different hypothetical cases occurring online (Kiss, 2017). The questionnaire was sent to social work and law school students in Hungary. Prevalence and levels of aggression and its manifestation as violence online proved to be not more severe than in offline social relations. Law students were more aware than students of social work that online hostile acts are discrediting. Students of social work were significantly more …

The Effects Of Decoding Instruction On Oral Reading Fluency For Older Students With Reading Delays, Gaige J. Johnson

Dissertations

Struggling older readers often have difficulty with early decoding skills (Tolman, 2005; Toste, Williams, & Capin, 2017). If they are unable to master decoding, they may have difficulty with more complex skills, such as passage reading fluency. The current study extends research on reading fluency for older students by evaluating the combined effects of a phonics procedure and a fluency-building strategy on their reading fluency. Participants were older students with below grade level reading performance who had deficits in oral reading fluency and decoding. Dependent variables were the number of correctly sorted word patterns and the number of correct words …

Development Of Semantic Reference For Location Symbols By Bottlenose Dolphins (Tursiops Truncatus) Using A Two-Way Communication Keyboard, Alyssa Taylor

Master's Theses

The ability for humans to communicate with another species has been an aspiration and well documented. One example is through training animals to make associations between a designated cue and conditioned response (Pryor, 1986). Two-way communication, however, in which both species can express wants/needs has been predominantly pursued with apes and dolphins. Studies conducted by Louis Herman demonstrated the capabilities of dolphins to comprehend complex semantic and syntactic commands in an artificial language system (Herman, Richards, & Wolz, 1984). Researchers working with primates have used American Sign Language, a computer keyboard system with discrete lexigrams, and a portable lexigram keyboard …

Affective Images Of Climate Change: Analysis And Database Development, Elizabeth Lehman

All NMU Master's Theses

Although climate change has become an increasingly popular topic in both research and the public-eye, there is little standardization of the images used to represent it. The differences in expert and non-expert climate imagery is also problematic. This study aims to resolve both of these issues: first by analyzing participants’ ratings of 320 images on their relevance to climate change as well as emotional arousal and valence; then by compiling these images and their affective characteristics into a database for use in future climate-related research. Participants’ environmental attitudes were surveyed to investigate the relationship between attitudes and image ratings. High-arousal, …

Application Of A Three-Lever Drug Discrimination Method To Differentiate The Interoceptive Stimulus Effects Of 3, 4-Methylenedioxypyrovalerone And 4-Methylmethcathinone In Male Sprague-Dawley Rats, Trent Bullock

Masters Theses

Psychoactive “bath salts” represent a continuing drug abuse problem. The synthetic cathinones, 3, 4-methylenedioxypyrovalerone (MDPV) and 4-methylmethcathinone (4-MMC) are popular constituents of “bath salts” in the United States and the United Kingdom, respectively. Addiction to these substances has proven difficult to treat, possibly requiring targeted therapeutics. Drug discrimination is a preclinical assay that may aid in treatment development. Thus far, two-lever (drug vs no drug) discrimination studies have exhibited asymmetrical substitution patterns between 4-MMC and MDPV. Therefore, a three-lever discrimination method was employed in which 12 male Sprague-Dawley rats were trained to discriminate 0.5 mg/kg MDPV, 2.0 mg/kg 4-MMC, and …

A Parametric Analysis Of Choice Under Risk, David W. Sottile

Masters Theses

Accurate assessment of risk propensity is important because risky choices underlie a broad range of behavioral problems. The Balloon Analogue Risk Task (BART) is an assessment that measures propensity to engage in risky choice. While this is a useful assessment, the BART changes two variables that affect risky choice simultaneously, probability of an undesirable outcome and stake size, which cannot be separated within the context of the BART. The goal of this study was to evaluate the separate and combined effects of key factors that are likely to risky choice (Magnitude of payoff, probability of an undesirable outcome, and stake …

Contribution Of Monoaminergic Mechanisms To The Discriminative Stimulus Effects Of 3,4-Methylenedioxypyrovalerone (Mdpv) In Sprague-Dawley Rats, Harmony I. Risca

Masters Theses

3,4-Methylenedioxypyrovalerone (MDPV) is a popular synthetic cathinone reported to have a high abuse potential and comparable pharmacological actions to those of cocaine. The aim of this study was to evaluate a variety of monoaminergic agents for substitution, potentiation, or antagonism in rats trained to discriminate MDPV. Male Sprague-Dawley rats were trained to discriminate 0.5 mg/kg MDPV and a variety of monoaminergic drugs were tested for substitution and/or potentiation of the MDPV cue. In separate experiments, stimulus antagonism tests were conducted with selected dopamine antagonists or serotonin antagonists in rats trained to discriminate 1 mg/kg MDPV. Full substitution for MDPV was …

Beauty As A Confounding Variable: Refining Measure Of Viewing Time, Rachael Caryn Pinkerman

Theses and Dissertations

Current research on viewing time measures of sexual attraction fail to explore potential confounding variables of viewing time. One viewing time measure, the LOOK, has been shown to be reliable over time and generally correlated with self-reported sexual orientation but has been unable to differentiate between a non-offending group and an offending group of individuals. This study utilizes the LOOK to examine the relationship between viewing time and a potential confounding variable of viewing time, beauty, using two constructs of beauty (facial beauty and full-body beauty). Facial beauty scores were created by measuring the degree of adherence to four universal …

Evaluation Of Generalized And Specific Token Reinforcement Using A Paired Stimulus Preference Assessment And Progressive Ratio Schedules, Haily K. Traxler

Masters Theses

Skinner (1953) stated that the effects of generalized conditioned reinforcers should maintain longer than specific conditioned reinforcers because their effects are not dependent on a particular motivating operation. Tokens easily model different levels of generality because tokens can be paired with one or more back-up reinforcers. In the current study, three types of tokens were assessed that could be exchanged for either salty snacks, food and drinks offered in a small marketplace, or money on a gift card. Token preferences were assessed using a Paired Stimulus preference assessment and a progressive ratio (PR) task. The results of the preference assessment …

Examining The Associative Learning And Accumbal Dopaminergic Mechanisms Of Caffeine Reinforcement, Curtis Bradley

Electronic Theses and Dissertations

Caffeine is the most consumed psychoactive substance in the world, and most caffeine consumption in coffee and energy drinks is intended to produce a psychoactive effect. However, caffeine is not a primary reinforcer in preclinical paradigms – non-human species do not reliably take the drug to produce a psychoactive effect. However, caffeine is a ‘reinforcement enhancer’ in preclinical models; the effects of caffeine increase the motivation to obtain other non-drug reinforcers. The overall goal of this project was to determine if these reinforcement enhancing effects of caffeine could promote caffeine self-administration and to subsequently investigate the behavioral and neurochemical underpinnings …

The Examination Of Discrimination And Social Bias Toward Interracial Relationships, Tarah Midy

Graduate Dissertations and Theses

Although rates of approval toward interracial couples are increasing (Carroll, 2007), interracial couples report facing prejudice and discrimination including disapproval and ostracism from family, friends, and the general public (Carbone-Lopez, 2013; Martin, Campbell, Ueno, Fincham, 2013; Potter & Thomas, 2012; Troy, Lewis-Smith, Laurenceau, 2006). However, there is growing evidence as acceptance rates and challenges faced by couples vary (Pew Research Center, 2012, Golebiowska, 2007), that experiences are different for couples depending on the racial group and gender of both partners involved.

To better understand the experience of different interracial couples, I conducted two studies to examine the particular stressors they …

Gene-Environment Interaction: Brain-Derived Neurotrophic Factor (Bdnf) As A Moderating Factor For The Effects Of Exercise And Diet On Cognitive And Mental Health: The Cache County Study On Memory In Aging, Chelsea L. Sanders

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

The Cache County Study on Memory in Aging, funded by the National Institute on Aging, studied longitudinal changes in memory and aging over 12 years’ follow-up in a population-based sample of 5,092 older adults in semirural Cache County, UT. Among the extensive interview procedures, researchers collected information regarding the participants’ demographics, health, genetic factors, diet, physical activity, and cognitive abilities. This study has allowed researchers to investigate how genetic and modifiable lifestyle factors interact to predict health, cognitive function, and psychological wellbeing in older adults.

Diet and exercise are important lifestyle factors in maintaining cognitive health and psychological wellbeing throughout …

Underrepresentation Of Hispanic Bilingual Students In Gifted And Talented Programs: The Role Of Teacher Expectations, Melissa I. Leon Leal

Theses and Dissertations

Participants will include approximately 100 pre-service teachers and currently practicing teachers in the community. Measures will include a demographic survey, vignettes for identifying giftedness which describe bilingual and monolingual potential gifted students across three ethnic groups, and a survey about student qualities that includes both quantitative and qualitative items. Results and implications …

A Multimodal Assessment Of Disgust In Response To Traumatic Event Reminders Among Adolescents, Teah-Marie R. Bynion

Graduate Theses and Dissertations

The majority of youth will report traumatic event exposure by the time they reach adulthood. Research suggests exposure to such events is linked to myriad negative outcomes. Not all traumatic events are alike, however; evidence suggests that, compared to non-interpersonal events, interpersonal events in which another person intentionally perpetrates harm are linked to elevations in the likelihood of negative outcomes, including posttraumatic stress disorder (PTSD). One reason for this discrepancy is that interpersonal traumatic events may elicit greater levels of disgust. However, this is a very under-developed research base, no study has examined this question among youth. The current study …

It's Not Just A Dog: The Role Of Companion Animals In The Family's Emotional System, Cassandra Leow

College of Education and Human Sciences: Dissertations, Theses, and Student Research

Past studies have looked into the role of companion animals in families. This study intended to explore the role of companion animals in the family’s emotional system through the lens of Bowen Family Systems Theory. Data from a study on companion animal loss and grief were used. A qualitative phenomenological approach was adopted to analyze the data from interviews. Three primary themes emerged from the data: balanced family emotional system, response to relational anxiety and role of the absence companion animal. The first theme suggested that human family members and companion animals developed a balanced family emotional system through companion …

Goats Prefer Positive Human Emotional Facial Expressions, Christian Nawroth, Natalia Albuquerque, Carine Savalli, Marie-Sophie Single, Alan G. Mcelligott

Social Cognition Collection

Domestication has shaped the physiology and the behaviour of animals to better adapt to human environments. Therefore, human facial expressions may be highly informative for animals domesticated for working closely with people, such as dogs and horses. However, it is not known whether other animals, and particularly those domesticated primarily for production, such as goats, are capable of perceiving human emotional cues. In this study, we investigated whether goats can distinguish human facial expressions when simultaneously shown two images of an unfamiliar human with different emotional valences (positive/ happy or negative/angry). Both images were vertically attached to a wall on …

The Underdog Narrative In Movies: When Our Memories Fail Us, Nadav Goldschmied, Jessica Ruiz, Sydney Olagaray

Heroism Science

Heroes who win are adulated. Underdogs are a special class of heroes who are facing especially daunting odds. Why do people extend support to underdog entities in light of their bleak odds for triumph? The current study explored the idea that the underdog narrative is one of ultimate success and that this schema is strong enough to elicit false memories. We surveyed participants’ recollections of two boxing movies. As predicted, participants accurately remembered James Braddock beating the world champion in the end of Cinderella Man (underdog consistent plot) but failed to recall Apollo Creed beating Rocky Balboa in Rocky I …

Insufficient Effort Responding On Mturk Surveys: Evidence-Based Quality Control For Organizational Research, Lee Cyr

Dissertations and Theses

Each year, crowdsourcing organizational research grows increasingly popular. However, this source of sampling receives much scrutiny focused on data quality and related research methods. Specific to the present research, survey attentiveness poses a unique dilemma. Research on updated conceptualizations of attentiveness--insufficient effort responding (IER)--shows that it carries substantial concerns for data quality beyond random noise, which further warrants deleting inattentive participants. However, personal characteristics predict IER, so deleting data may cause sampling bias. Therefore, preventing IER becomes paramount, but research seems to ignore whether IER prevention itself may create systematic error. This study examines the detection and prevention of IER …

Double Dissociation Of The Anterior And Posterior Dorsomedial Caudate-Putamen In The Acquisition And Expression Of Associative Learning With The Nicotine Stimulus, Sergios Charntikov, Steven T. Pittenger, Natashia Swalve, Ming Li, Rick A. Bevins

Department of Psychology: Faculty Publications

Tobacco use is the leading cause of preventable deaths worldwide. This habit is not only debilitating to individual users but also to those around them (second-hand smoking). Nicotine is the main addictive component of tobacco products and is a moderate stimulant and a mild reinforcer. Importantly, besides its unconditional effects, nicotine also has conditioned stimulus effects that may contribute to the tenacity of the smoking habit. Because the neurobiological substrates underlying these processes are virtually unexplored, the present study investigated the functional involvement of the dorsomedial caudate-putamen (dmCPu) in learning processes with nicotine as an interoceptive stimulus. Rats were trained …

An Analysis Of Innovate Training With Bottlenose Dolphins (Tursiops Truncatus), Raymond John Van Steyn

Theses and Dissertations

The National Aquarium in Baltimore, Maryland conducted a training program in 2014 to develop a gestural command for their dolphins called “innovate”. This training paradigm was developed to resemble the seminal research by Pryor, Haag and O’Reilly (1969), as well as more recent efforts of Braslau-Schneck (1993) and Kuczaj and Eskelinen (2014) of training dolphins to offer “creative” behaviors not developed through conventional methods of behavioral modification, such as shaping. The goal of the present study was to observe records taken during the National Aquarium’s training procedure as well as data collected ~3 years after said training in order to …

Expectations For Dog Ownership: Perceived Physical, Mental And Psychosocial Health Consequences Among Prospective Adopters, Lauren Powell, Debbie Chia, Paul Mcgreevy, Anthony L. Podberscek, Kate M. Edwards, Brendon Neilly, Adam J. Guastella, Vanessa Lee, Emmanuel Stamatakis

Human-Companion Animal Relationships Collection

Dog ownership is popular worldwide, with most human-dog dyads forming successful attachment bonds. However, millions of dogs are surrendered to animal shelters annually, possibly due to mismatches between owner expectations and the realities of dog ownership. The aim of the current study was to explore the benefits and challenges people expect from dog ownership and how these expectations vary with previous ownership history. An Australian-wide sample of 3465 prospective adopters completed a self-administered online questionnaire about the physical, mental and psychosocial health benefits and challenges they associated with dog ownership. Among the potential benefits, respondents expected increased walking (89%), happiness …

A Participatory Action Research Using Photovoice To Explore Well-Being In Young Adults With Autism, Gary Yu Hin Lam

USF Tampa Graduate Theses and Dissertations

Young adults with autism transitioning from school to adulthood are commonly described as exhibiting poor outcomes. Although there has been research efforts measuring quality of life and life satisfaction in individuals with autism, these conceptualizations of well-being are still predominantly deficit-focused and based on normalizing ideals of the dominant culture. Only by incorporating individuals with autism’s perspectives and involving their meaningful participation in research can we better understand and promote well-being among individuals with autism. The present study aims to explore young adults with autism’s ideas about well-being. I conducted a Photovoice project using a participatory action research approach with …

Performing The Quality Of Imperceptible Interactions Between Individuals: A Technological Challenge Regarding The Collective, Marine Theunissen

Proceedings from the Document Academy

Contemporary technologies allow incredible possibilities of capturing individuals, but a problem arises when it comes to capturing a chorus, that is to say a "collective body" in motion. This proposal will address the problem of the sensitive capture of the quality of the interrelations between individuals, and of their refined interpretation through algorithms to "output” them in other forms. We will address two questions on the subject: how to capture the relations between individuals within a collective? How to create a circular-causal loop, whose artistic material (the digital data) is the interrelations of a collective, without engendering redundancy in their …

Should Patients With Diabetes Be Encouraged To Integrate Social Media Into Their Care Plan?, Arun R. Nelakurthi, Angela Marinilli Pinto, Curtiss B. Cook, Lynne Jones, Mary Boyle, Jieping Ye, Theodoros Lappas, Jingrui He

Publications and Research

AIM: To evaluate the use of social media of individuals with diabetes mellitus (DM).

MATERIALS & METHODS: Both web-based and in-clinic surveys were collected from individuals with DM. Descriptive and correlation analyses were employed to evaluate respondents' diabetes-specific social networking site behaviors.

RESULTS: Forty-five patients with DM completed the web-based survey and 167, the clinic-based survey, of whom only 40 visited diabetes-specific social networking sites. Analysis of online survey data indicated that self-reported adherence to lifestyle recommendations was significantly correlated (p < 0.01) with visiting the sites. Clinic-based survey data found that patients who reported using DM-specific web sites monitored home glucose values more often and had better compliance with insulin administration (both p < 0.05) compared with nonusers.

CONCLUSION: This study provides insight into why individuals visit DM-specific social networking sites. Certain self-management behaviors may improve as …

Chronic Hippocampal Abnormalities And Blunted Hpa Axis In An Animal Model Of Repeated Unpredictable Stress, Moustafa Algamal, Joseph O. Ojo, Carlyn P. Lungmus, Phillip Muza, Constance Cammarata, Margaret J. Owens, Benoit C. Mouzon, David M. Diamond, Michael Mullan, Fiona Crawford

Psychology Faculty Publications

Incidence of post-traumatic stress disorder (PTSD) ranges from 3 to 30% in individuals exposed to traumatic events, with the highest prevalence in groups exposed to combat, torture, or rape. To date, only a few FDA approved drugs are available to treat PTSD, which only offer symptomatic relief and variable efficacy. There is, therefore, an urgent need to explore new concepts regarding the biological responses causing PTSD. Animal models are an appropriate platform for conducting such studies. Herein, we examined the chronic behavioral and neurobiological effects of repeated unpredictable stress (RUS) in a mouse model. 12 weeks-old C57BL/6J male mice were …
