Autistic Traits And Executive Functioning, Meagan Smith

Scholars Week

Autism Spectrum Disorder is a term used to encompass all of the varying degrees of the developmental disorder known as Autism. Individuals with Autism Spectrum Disorder struggle with areas of executive functioning such as cognitive flexibility, planning, visual/visuo-spatial working memory, and verbal fluency compared to typically-developing individuals. This research project seeks to measure the amount of Autistic-like traits/tendencies of individuals who are not diagnosed with Autism Spectrum disorder and compare their level of Autistic tendencies to their ability to perform various cognitive tasks. Participants will first take the Autism Quotient--a questionnaire determining their level of autistic-like traits. Following this, participants …

Social Interactions Among Giant Panda Cubs (Ailuropoda Melanoleuca): An Investigation Into The Role Of Kin Recognition, Kelly M. Jackson

Undergraduate Distinction Papers

Although giant pandas (Ailuropoda melanoleuca) are known to be solitary in the wild, cubs engage in frequent bouts of affiliative behavior in captive settings. The goal of the project was to investigate whether kinship or familiarity based on housing influenced the frequency of social interactions within one-year old giant panda cubs. Data were collected from June through mid-July 2016 at the Chengdu Research Base of Giant Panda Breeding, Sichuan, China. Over 113 hours of behavioral observations were recorded on four sets of twins and one singleton, focusing specifically on affiliative behaviors. Time housed together was a significant predictor of the …

Eco-Anxiety At University: Student Experiences And Academic Perspectives On Cultivating Healthy Emotional Responses To The Climate Crisis, Anna Kelly

Independent Study Project (ISP) Collection

This research looks at the overall question of how planetary health impacts mental health and psychological welling. The central focus is eco-anxiety—mental distress caused by climate change and environmental degradation—and how it manifests in university students. In order to gather data for this research I collected 114 student survey responses, interviewed seven young adults (ages 20-25), and interviewed seven experts in the fields of psychology and environmental studies.

They survey results show high levels of general stress and anxiety, high levels of stress and anxiety related to climate change and the state of the world, and a very high level …

Challenging The Stereotype – Greek Life In The Media, Briana Trifiro

Honors Projects in Communication

Stereotypes are an undeniable aspect of today’s society. As demonstrated through a variety of mass communication theories, stereotypes are often formed as a result of exposure to mass media images. This concept is especially important today, as media messages permeate daily life in a variety of ways. From the news, to social media, to movies and television – media messaging is everywhere and impacts people on a daily basis. The purpose of this study is to produce a documentary video which demonstrates how negative media portrayals of Greek life lead to the formulation of stereotypes about college students affiliated with …

Timmy's In The Well: Empathy And Prosocial Helping In Dogs, Emily M. Sanford

Psychology Honors Projects

Dogs can empathetically evaluate humans’ emotional states. However, whether dogs are motivated by empathy to provide help to humans in need is unclear. In this study, dogs’ behaviors were observed while their owner sat behind a door and either cried or hummed. Dogs that were more skilled at regulating their emotional stress responses and had stronger bonds with their owners were more likely to help those owners. This supports the theory that an empathetic response is only possible when an individual can suppress their own distress enough to focus on helping someone else.

The Effects Of Provided Powerpoint Presentations On Student Perceptions Of Personal Responsbility, Sarah Elizabeth Mannon Cravero

Masters Theses & Specialist Projects

Psychologists have examined the effects of numerous variables on classroom performance, but little research exists to demonstrate how specific teaching techniques, specifically the provision of printed presentation notes (such as presentation slides), affects student perception of responsibility. This study sought to discover the impact that providing presentation slides for use during lecture would have on students’ performance, as well as their perceptions of personal responsibility. In order to determine the effects of provided presentation notes on performance and perceived responsibility, this study examined the self-efficacy and locus of control of students assigned to either take their own notes or to …

Signing To Maintain Joint Attention With Children With Down Syndrome, Rachel Dauer Burns

Masters Theses & Specialist Projects

The current study examined the role of two different methods of sign presentation on signed and spoken language acquisition of toddlers aged two to four years with Down syndrome (DS). The aim of this study was to determine if a method commonly used by native signers/Deaf mothers (referred to in this study as signing to maintain joint attention (SMJA)) was more effective than the method commonly used by hearing mothers and speech-language pathologists (referred to in this study as the triangular method of signing). Both methods were compared in a within-subject design for effects on the participants’ total number of …

The Influence Of Training Procedures On Generalization Performance In Scent-Detection Rats, Erin Watkins

Dissertations

The global illicit trade in tobacco products leads to an overall increase in the availability of tobacco, and this increase in tobacco availability and consumption undermines effective health, safety, and taxation policies in place to protect current and future populations. Dogs working at ports and customs have been trained to detect tobacco products and research has shown rats can detect tobacco-soaked filters (Mahoney et al., 2014). Cigarette smoking is the most common form of tobacco use, and cigarettes are the most commonly trafficked product in the illicit tobacco trade. In the current study, rats were trained to respond to filter …

Management And Leadership Style: Is Style Influenced By Engineering Education?, Arsalan Khan

Masters Theses & Specialist Projects

Leadership Development Programs (LDPs) programs are employed by firms globally in different multiple manners that are aimed at accelerating the development and growth of highly capable candidates. Among these candidates, depending on the particular LDP, may be those possess engineering skills typically afforded through engineering education as measured by completion of an engineering degree. Infrastructure reductions might be afforded corporations if multiple LDPs could be supplanted with one program such as an Engineering Leadership Development Program. In practice, however, economic constraints limited the total sample population of this category to 67 (48 with engineering degrees and 15 without). Employing SPSS …

Does Variability Across Events Affect Verb Learning In English, Mandarin, And Korean?, Jane B. Childers, Jae H. Paik, Melissa Flores, G. Lai, Megan Dolan

Psychology Faculty Research

Extending new verbs is important in becoming a productive speaker of a language. Prior results show children have difficulty extending verbs when they have seen events with varied agents. This study further examines the impact of variability on verb learning and asks whether variability interacts with event complexity or differs by language. Children (aged 2 1⁄2 to 3 years) in the United States, China, Korea, and Singapore learned verbs linked to simple and complex events. Sets of events included one or three agents, and children were asked to extend the verb at test. Children learning verbs linked to simple movements …

Syntactic Adaptation To Relative Clause Sentence Processing: Contributions Of Experience And Memory, Elias Blinkoff , '17

Senior Theses, Projects, and Awards

One of the most robust findings in psycho linguistics is that object-extracted relative clauses (ORCs) are more difficult to process than subject-extracted relative clauses (SRCs) (Traxler, Morris, & Seely, 2002; King & Just, 1991; Ford, 1983). However, the reasons for this are still controversial. One view attributes this difficulty to experience: ORCs are harder to process because they are more rarely encountered than SRCs (Wells, Christiansen, Race, Acheson, & MacDonald, 2008; Gennari & MacDonald, 2008; MacDonald & Christiansen, 2002). Another view is that the word order of ORCs places a larger burden on working memory than SRCs (Miller & Chomsky, …

Microglial Location, Morphology, And Cognitive Performance In Mold-Exposed Mice, Karen Marmon

Theses and Dissertations

We examined changes in brain microglia and cognitive performance following mold exposure and doxycycline administration. Neither mold nor doxycycline caused significant changes in microglial location or morphology. While greater numbers of microglia in control-treated mice were linked with improved performance, greater numbers in mold-treated mice were linked to memory impairments.

Law And Identifiability, Daphna Lewinsohn-Zamir, Ilana Ritov, Tehila Kogut

Indiana Law Journal

Psychological studies have shown that people react either more generously or more punitively toward identified individuals than toward unidentified ones. This phenomenon, named the identifiability effect, has received little attention in the legal literature, despite its importance for the law. As a prime example, while legislators typically craft rules that would apply to unidentified people, judges ordinarily deal with identified individuals. The identifiability effect suggests that the outcomes of these two forms of lawmaking may differ, even when they pertain to similar facts and situations.

This Article is a preliminary investigation into the relevance of the identifiability effect for law …

Distributive Justice For Volunteers: Extrinsic Outcome Distribution Matters, Christine Hurst, Lisa L. Scherer, Joseph A. Allen

Psychology Faculty Publications

Volunteer organizations continue to suffer from turnover; the current volunteer rate is the lowest since 2002. Distributive justice, satisfaction, and extrinsic outcome importance were examined as influences of volunteer intention to quit. Survey results from 294 volunteers revealed that those who perceived less than fair distribution of extrinsic outcomes experienced heightened intention to quit compared to those who perceived fair distribution. Overall satisfaction partially mediated this relationship. We explored the potential moderating role of volunteers’ assessment of the importance of extrinsic outcomes on the overall mediated relationship.

Effects Of Playing Computerized Versus Tactile Learning Games On Preschoolers’ Attention Skills And Comprehension: A Pilot Study, Samantha Malick

Honors Theses

The ability to attend to relevant information and resist attention to distractors is important for children’s cognitive development. Much has been written in the news about the impact of electronic media on children’s development of attention skills, but little research has been done explicitly comparing children’s attention to relevant information and resistance to distractions across activities that are presented as either a computerized or tactile learning game. The goal of this study is to compare levels of attention and distraction among preschool-aged children while they engage in a common childhood activity, playing a board game that is either presented in …

Remembering Negdels: Nostalgia, Memory & Soviet-Era Herding Collectives, Maya Sutton-Smith

Independent Study Project (ISP) Collection

During the socialist period Mongolia’s nomadic herders were grouped into collective herding units called negdels. Today, over twenty years after Mongolia transitioned to democracy, herding has been privatized completely and negdels are a distant memory. This study explores the history of negdels by conducting twenty-five oral interviews with herders about their memories of collective herding. This study focuses on a soum in the Mongolian countryside, Bayandelger, while also incorporating interviews with people from Ulaanbaatar. Bayandelger is a unique location for this project because it was selected by the Soviets to receive assistance in an effort to make it a model …

Stress And Prosocial Decision Making: The Influence Of Acute Stress On Trust Behavior, Stephanie Ross Potts

Dissertations (1934 -)

While acute stress exposure has been associated with modulation of risk-taking in decision making, the influence of stress on social decision making and trust has not been well-researched. The current study aims to advance scientific understanding of how stress influences trust behavior. Ninety-six participants (49 male and 47 female) engaged in an adapted Trust Game task, randomly assigned between-subjects to either an acute stress (cold pressor test or socially evaluative cold pressor test) or control group. The Trust Game was administered at different time points with respect to stress exposure to examine the potential differential roles of temporally distinct stress …

Pnf 2.0? Initial Evidence That Gamification Can Increase The Efficacy Of Brief, Web-Based Personalized Normative Feedback Alcohol Interventions, Sarah C. Boyle, Andrew M. Earle, Joseph W. Labrie, Daniel J. Smith

Heads Up!

Gamified interventions exploit the motivational characteristics of a game in order to provide prevention information and promote behavior change. Despite the modest effect sizes observed in increasingly popular web-based personalized normative feedback (PNF) alcohol interventions for college students, previous research has yet to consider how gamification might be used to enhance efficacy. This study examines whether a novel, gamified PNF intervention format, which includes a point-based reward system, the element of chance, and personal icons to visually represent users, is more effective in reducing short-term alcohol use than the standard web-based style of PNF currently used on college campuses. Two-hundred …

The Effects Of Delay And Probabilistic Discounting On Green Consumerism, Blake J. Bent

Psychology Theses & Dissertations

People have a tendency to discount outcomes that are delayed or probabilistic. In other words, people will sacrifice larger benefits for smaller benefits that are immediate or certain. For many environmentally-friendly (“green”) products, the financial benefits are both delayed and probabilistic. The current study examined how delay and probability, as well as frame and magnitude, influenced consumers’ decisions when comparing a conventional and green product. Participants were recruited from Amazon’s Mechanical Turk and completed one of two experiments. In each experiment participants chose between a conventional product (low initial cost, high operating cost) and green product (high initial cost, low …

Does Making Something Move Matter? Representations Of Goals And Sources In Motion Events With Causal Sources, Laura Lakusta, Paul Muentener, Lauren Petrillo, Noelle Mullanaphy, Lauren Muniz

Department of Psychology Faculty Scholarship and Creative Works

Previous studies have shown a robust bias to express the goal path over the source path when describing events (“the bird flew into the pitcher,” rather than “… out of the bucket into the pitcher”). Motivated by linguistic theory, this study manipulated the causal structure of events (specifically, making the source cause the motion of the figure) and measured the extent to which adults and 3.5- to 4-year-old English-speaking children included the goal and source in their descriptions. We found that both children's and adults’ encoding of the source increased for events in which the source caused the motion of …

Evaluating Preference Stability Among Individuals With Alzheimer’S Disease, Sabrine Maali

Thesis Projects

In the behavior-analytic field, preference assessments are conducted to determine specific items to use as reinforcers to reduce aberrant behavior as well as increase appropriate behavior. We examined the consistency of preference-assessments results among individuals with Alzheimer’s Disease (AD) to ensure effective reinforcers are used in behavioral interventions. Specifically, we examined if identified reinforcers remained consistent for individuals with AD throughout the study or if preferences shifted. The experimental procedure consisted of a series of multiple-stimulus preference assessments without replacement (MSWO); data were analyzed for preference shifts. Results showed variability with one individual’s preferences, whereas the other individual’s preferences remained …

Volunteer Engagement And Retention: Their Relationship To Community Service Self-Efficacy, Elizabeth Harp, Lisa L. Scherer, Joseph A. Allen

Psychology Faculty Publications

The declining number of U.S. volunteers is troubling, necessitating improved understanding of drivers of volunteer retention such as volunteer engagement. We utilized the job demands-resources model to investigate the moderating role of community service self-efficacy (CSSE) on the relationships between two demands (organizational constraints and role ambiguity) and volunteer engagement. Volunteers (N = 235) from three U.S. nonprofit organizations participated in a survey as part of a volunteer program assessment. Volunteers who encountered greater organizational constraints and role ambiguity were less engaged. In addition, CSSE attenuated the negative relationship between organizational constraints and engagement, but not the negative association …

The Development Of Autism Spectrum Disorders: Variability And Causal Complexity, Robert H. Wozniak, Nina B. Leezenbaum, Jessie B. Northrup, Kelsey L. West, Jana M. Iverson

Psychology Faculty Research and Scholarship

The autism spectrum is highly variable, both behaviorally and neurodevelopmentally. Broadly speaking, four related factors contribute to this variability: (1) genetic processes, (2) environmental events, (3) gene × environment interactions, and (4) developmental factors. Given the complexity of the relevant processes, it appears unlikely that autism spectrum atypicalities can be attributed to any one causal mechanism. Rather, the development of neural atypicality reflects an interaction of genetic and environmental risk factors. As the individual grows, changes in neural atypicality, consequent variation in behavior, and environmental response to that behavior may become linked in a positive feedback loop that amplifies deviations …

Using Auditory Extinction Cues To Mitigate Resurgence, Samuel Shvarts

Theses and Dissertations

Resurgence is a laboratory model of treatment relapse revealing the effects of treatment-integrity errors on problem behavior eliminated through treatment with differential reinforcement of alternative behavior (DRA). This study took a translational approach to assess the effects of an auditory extinction cue (e-cue) to mitigate resurgence of target responding in children with autism using arbitrary responses to simulate target and alternative responding. The auditory cue was a recorded praise statement introduced in Phase 2 and remained in one of the test conditions in Phase 3. In 8 of 12 resurgence test comparisons (with and without the e-cue), responding was mitigated …

Stress And Decision Making: Effects On Valuation, Learning, And Risk-Taking, Anthony J. Porcelli, Mauricio R. Delgado

Psychology Faculty Research and Publications

A wide range of stressful experiences can influence human decision making in complex ways beyond the simple predictions of a fight-or-flight model. Recent advances may provide insight into this complicated interaction, potentially in directions that could result in translational applications. Early research suggests that stress exposure influences basic neural circuits involved in reward processing and learning, while also biasing decisions toward habit and modulating our propensity to engage in risk-taking. That said, a substantial array of theoretical and methodological considerations in research on the topic challenge strong cross study comparisons necessary for the field to move forward. In this review …

Effects Of Pre-Conditioning On Behavior And Physiology Of Horses During A Standardised Learning Task, Kate Fenner, Holly Webb, Melissa Starling, Rafael Freire, Petra Buckley, Paul D. Mcgreevy

Animal Training and Obedience Collection

Rein tension is used to apply pressure to control both ridden and unridden horses. The pressure is delivered by equipment such as the bit, which may restrict voluntary movement and cause changes in behavior and physiology. Managing the effects of such pressure on arousal level and behavioral indicators will optimise horse learning outcomes. This study examined the effect of training horses to turn away from bit pressure on cardiac outcomes and behavior (including responsiveness) over the course of eight trials in a standardised learning task. The experimental procedure consisted of a resting phase, treatment/control phase, standardised learning trials requiring the …

The Lateral Occipital Cortex Is Selective For Object Shape, Not Texture/Color, At Six Months, Lauren L. Emberson, Stephen L. Crosswhite, J. E. Richards, Richard N. Aslin

Faculty Publications

Understanding howthe human visual system develops is crucialto understandingthe nature and organization of our complex and varied visual representations. However, previous investigations of the development of the visual system using fMRI are primarily confined to a subset of the visual system (high-level vision: faces, scenes) and relatively late in visual development (starting at 4 –5 years of age). The current study extends our understanding of human visual development by presenting the first systematic investigation of a mid-level visual region [the lateral occipital cortex (LOC)] in a population much younger than has been investigated in the past: 6 month olds. We …
