Effects Of Nonexamples On Concept Formation, Catherine Louise Williams

Graduate Theses, Dissertations, and Problem Reports (ETD)

Concept formation is affected by the examples and nonexamples provided during training, but the degree to which examples and nonexamples should differ is unknown. Two experiments compared concept formation when different kinds of nonexamples were used during training. Both experiments included a within-subject comparison of concept formation following three training conditions: a) nonexamples that were more similar to the examples, b) nonexamples that are less similar to the examples, and c) no nonexamples. Arbitrary concepts were trained in Experiment 1 and concepts akin to those that could be taught in a classroom were trained in Experiment 2. Before and after …

An Analysis Of Coordinated Responding, Brian Katz

Graduate Theses, Dissertations, and Problem Reports (ETD)

Experimental analyses of coordinated responding (i.e., cooperation) have been derived from a procedure described by Skinner (1962) in which reinforcers were delivered to a pair of subjects (a dyad) if both responded within a short interval, thus satisfying a mutual-reinforcement contingency. Although it has been suggested that this contingency enhances rates of temporally coordinated responding, limitations of past experiments have raised questions concerning this conclusion. The present experiments assessed three of those limitations by holding the schedule of reinforcement (Experiment 1: fixed-ratio 1; Experiment 2; variable-interval 20 s) constant (1) across phases and (2) between dyad members, and (3) varying …

Effects Of Blended Integrity Failures On Reinforcement-Based Interventuions, Stephanie Hope Jones

Graduate Theses, Dissertations, and Problem Reports (ETD)

Reinforcement-based interventions reduce problematic behavior when implemented as designed. However, the effectiveness of these interventions may decrease when deviations from treatment protocols (i.e., treatment-integrity errors) occur. Treatment-integrity errors differentially impact reinforcement-based interventions based on multiple factors, including how frequently errors occur and the intervention type. Even nominally acceptable integrity values (e.g., 80%) may be detrimental depending on the intervention. To evaluate this possibility and directly compare the effectiveness of multiple reinforcement-based interventions, we conducted two within-subject evaluations using laboratory arrangements. For both experiments, we recruited four undergraduate students to participate in a computer task that involved clicking on moving circles …

A Translational Analysis Of Renewal Following Dro With Human Subjects, Kacey R. Finch

Graduate Theses, Dissertations, and Problem Reports (ETD)

Renewal is a type of behavioral relapse that is dependent on changes in contextual stimuli in the environment. The current study investigated ABA renewal of responding that had been previously reduced by a differential reinforcement of other behavior (DRO) procedure. ABA renewal refers to the context associated with three phases of behavioral treatment; Context A is present during baseline, Context B is present during treatment, and the post-treatment context returns to Context A (i.e., renewal test). Undergraduate college students participated in a Zoom video call during which they responded by clicking the mouse on a rectangle in a computer program …

Effects Of Acute And Chronic Nicotine Administration On Choice Of Probabilistic Outcomes, Katya A. Nolder

Graduate Theses, Dissertations, and Problem Reports (ETD)

Risky choice can be operationally defined as the choice for a larger, uncertain reinforcer over a smaller, certain reinforcer. Research suggests smokers engage in more risky or maladaptive decisions when compared to nonsmokers. The relation between nicotine and risky choice could benefit from further investigation, since nicotine is the active substance of tobacco products that maintains tobacco addiction. Acute nicotine administration has shown to alter risky choice; however, since the everyday smoker uses nicotine repeatedly, more research on chronic administration is warranted and would allow for assessment of tolerance or sensitization of these effects. The present study investigated effects of …

A Comparison Of Traditional Aggregated Data To A Comprehensive Second-By-Second Data Depiction In Functional Analysis Graphs, Erin Mackelvie

University of the Pacific Theses and Dissertations

Functional analyses (FAs) are an important component of treatment and the data gathered from FAs are often graphed in an aggregate or summary format, such as mean rate per session. Given the prevalence of undifferentiated analyses, it may be that this common method of data depiction is incomplete. In this paper, we compare the traditional aggregate method to a comprehensive second-by-second demonstration of the data including all appropriate and inappropriate responses emitted, as well as programmed and accidental antecedent and consequent variables, which may help further clarify the results of a functional analysis. We compared the functional analysis results of …

The Effects Of Escalated Cocaine Intake On Decision-Making Dynamics, Mcallister Stephens

Theses and Dissertations--Psychology

Cocaine Use Disorder (CUD) is characterized partly by the use of cocaine at the expense of other alternatives, in other words, it is a decision-making pathology (Kalivas & Volkow, 2005). Concurrent choice tasks assess decision-making in a dynamic scenario that more closely resembles real life. Value-based decision-making is an important facet of understanding the addictive properties of drugs of abuse. In order to compare two value-based theories of addiction (habit theory and relative value theory), a concurrent choice task was run in tandem with an escalation procedure. First, animals were trained on a choice task until stable, then trained on …

Influence Of Increased Options On Performance Generalization Across Two Variations Of The Monty Hall Dilemma, Robert A. Southern

College of Graduate Studies: Theses & Dissertations

The Monty Hall dilemma (MHD) is a probability puzzle at which humans consistently fail to adopt the optimal winning strategy. The participant chooses between three identical doors, behind one of which is a valuable prize. After the participant makes their initial decision, the host reveals that there is nothing behind one of the two remaining doors, then asks the participant if they would like to stay with their originally selected door or switch to the remaining unopened door. The optimal choice is to switch to the previously unchosen door, which increases the probability of winning from 33% to 67%. Despite …

Pharmacokinetics And Reward-Related Behaviors Of Ethanol In Male And Female Japanese Quail (Coturnix Japonica), Shannon Eaton

Theses and Dissertations--Psychology

Ethanol is one of the most widely used and abused drugs. Problem use is associated with many different health problems and the economic burden is in the billions of dollars. Additionally, many people have difficulty controlling their ethanol consumption and about 5% of adults end up with an alcohol use disorder (AUD). Many people with an AUD often find themselves in a cycle of binge, remission, and relapse.

Following ethanol consumption ethanol enters the bloodstream from the small intestine where it gets distributed to peripheral tissues. Ethanol in the bloodstream is cleared from the system by the liver. The primary …

Mapping Out Learning: How Aerobic Exercise, Sex And Alzheimer's Disease Impact Learning, Grace G. Bouker

Senior Independent Study Theses

Exercise has the power to ameliorate the outward symptoms of Alzheimer’s Disease (AD) by rescuing hippocampal-dependent learning and memory. The goal of this research was to map out how exercise and sex impact behavioral learning in AD mouse models by looking outside of the traditional measurements in the Morris water maze (MWM), as they fail to describe the process of learning itself. I calculated heading error at maximum velocity, manually categorized search strategy in the MWM across trials, and determined flexibility in the probe trial for transgenic and wild-type mice who were exposed to exercise or control housing. Mice significantly …

Response Interruption And Redirection (Rird) As A Treatment For Vocal Stereotypy In Children Who Are Dually Diagnosed With Autism And Down Syndrome, Stacy Taylor

Theses and Dissertations

Individuals who are dually diagnosed with Down Syndrome (DS) and autism spectrum disorders (ASD) frequently engage in vocal stereotypy that can interfere with learning, impede socially appropriate behavior, and disrupt others. Response interruption and redirection (RIRD) is an intervention that blocks and redirects stereotypy to reduce behavior. Studies on RIRD, while varied in their overall approach, have overwhelmingly been shown to be effective in clinical settings for children with ASD. There are few studies that have evaluated this procedure in more natural settings and with other diagnoses. Given that ASD is prevalent in those with DS and that stereotypy is …

Online Training To Improve Job Coaches’ Support Of Minimally Verbal And Nonverbal Adults With Autism Spectrum Disorder, Erin Brooker Lozott

Theses and Dissertations

Although a sizeable percentage of individuals with autism spectrum disorder (ASD) are minimally verbal or nonverbal, there is limited research on how to best support these individuals in employment settings. Job coaches working with this population should receive specialized training in evidence-based practices (EBP) for ASD to ensure optimal outcomes. This study describes the development, implementation, and evaluation of an online training program for job coaches focused on a behavior skills training approach supporting the use of augmentative and alternative communication. Twenty-two job coaches completed the study. Pre- and posttraining measures were used to evaluate knowledge, self-efficacy, and belief systems …

Decipher The Effect Of Gamification In Harnessing Boredom And Improving Performance, Zhuoyi Zhao

Theses and Dissertations (Comprehensive)

My thesis investigates the effectiveness of gamification in harnessing boredom and improving performance in a repetitive work process. In video games, “loot” rewards are unpredictable, intermittent gains used to motivate players to repeat boring actions. In a 2 X 2 experiment, I examine how loot rewards in point form may impact 1) disengagement, which is an immediate outcome of boredom, and 2) performance in settings where the points have and do not have cash value, respectively. More specifically, I manipulate the level of point reward unpredictability (fixed versus loot) and whether point rewards have cash value (absent versus present).

Visual Perception And Action In Reaching During Upper Limb Obstacle Avoidance, Nondon Chakraborty

Theses and Dissertations (Comprehensive)

During everyday activities, people reach to specific objects with their hands and avoid obstacles. For people to move successfully through an obstacle gap, it is necessary to be able to accurately perceive the actions that the surroundings afford and adjust hand movements accordingly. Reaching behaviours, including planning (perception) and execution (action), depend on visual information. This study aimed to understand and detect the differences between perceptual judgment and actual performance of both hands during a reaching task at the time of obstacle avoidance by using a hand-scaled approach. Participants were young adults (male (n=7) and female (n=10) aged 18 to …

Variation In Personality Among Semi-Wild Myanmar Timber Elephants, Sateesh Venkatesh

Theses and Dissertations

This study examines two personality traits: exploration and neophobia, which could influence human-elephant conflicts. Thirty-one semi-wild elephants were tested over two trials using a custom novel puzzle tube containing three tasks and three rewards. Our studies show that elephants do vary significantly between individuals in both exploration and neophobia.

The Youthful Pandemic, Brook Sahlemariam

Nursing | Senior Theses

This paper attempts to examine the neurological, physical, and societal effects of e-cigarette use among youth and young-adults in North America. Furthermore, the paper investigates the parallels between e-cigarette users, tobacco users, and dual users in regard to behavioral patterns, reasons for use, and age of initiation.

Assessment Of Dopaminergic And Serotonergic Receptor Antagonists In Male Rats Trained To Discriminate 4-Methylmethcathinone (Mephedrone), Rachel L. Burroughs

Masters Theses

Preclinical drug discrimination studies of the synthetic cathinone, 4-methylmethcathinone (mephedrone) have demonstrated its effects are comparable to those of other popular psychostimulant drugs. Few studies have directly examined the contribution of specific neurotransmitter receptors to mephedrone’s discriminative stimulus effects. The present study investigated the role of dopamine and serotonin receptors in these effects. Eight adult male Sprague-Dawley rats were trained to discriminate 3.0 mg/kg mephedrone from saline. After dose-response curves were determined with mephedrone (0.375-3.0 mg/kg), a series of stimulus antagonism tests were conducted with dopamine antagonists (Sch 23390, haloperidol) and serotonin antagonists (WAY 100,635, MDL 100,907, pirenperone) administered as …

Effects Of Alcohol Intoxication On Hostile Attribution Bias And Relational Aggression In Women, Alita M. Mobley

Graduate Theses and Dissertations

Alcohol intoxication is consistently linked to physical and sexual aggression in men, but not women. The lack of evidence supporting the relationship between alcohol and aggression for women could be due to a failure to measure relational aggression (i.e., harmful social manipulation), the form of aggression more commonly employed by women. Further, alcohol intoxication may interfere with the interpretation of social cues, resulting in greater perceived provocation in ambiguous social interactions and increased aggression. The current study examined the relationship between alcohol intoxication and relational aggression in women and the extent to which interpretation of social cues (i.e., hostile attribution …

Envisioning Success: A Naturalistic Investigation Into Prospective Memory Performance, Reminder Use, And Memory Strategies In An Academic Context, John Whittemore

Honors Theses

Prospective memory encompasses the ability to remember to carry out future intentions. Prospective memory performance is essential for students. College students are expected to remember and complete a variety of assignments on a daily basis. In these naturalistic experiments taking place before and after COVID-19, college students were required to set academic goals for themselves for three consecutive days following specific guidelines. Each day, the participant identified a time specific academic goal and a non-time specific academic goal. Participants were randomizing assigned experimental or control condition. The experimental group performed an episodic future thinking exercise during encoding. Additionally, each time …

Personality And Mood For Non-Player Characters: A Method For Behavior Simulation In A Maze Environment, Noah L. Paige

Master's Theses

When it comes to video games, immersion is key. All types of games aim to keep the player immersed in some form or another. A common aspect of the immersive world in most role-playing games -- but not exclusive to the genre -- is the non-playable character (NPC). At their best, NPCs play an integral role to the sense of immersion the player feels by behaving in a way that feels believable and fits within the world of the game. However, due to lack of innovation in this area of video games, at their worst NPCs can jar the player …

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 …

Wicked Problems: Depression, Sebastian Wendolowski

English Department: Research for Change - Wicked Problems in Our World

Depression is a disorder that can affect anybody and is the leading cause of disability and disorders in the United States. This year, due to COVID-19, it has hit an all time high, affecting many more people. Suicide rates have been steadily growing across all ages, and this year is at a record high too, showing correlation with depression. There are two types of depression, major depressive disorder and chronic depressive disorder. Diagnosis of depression is typically done physically or through a questionnaire, which is compared into a DSM-5. There are many risk factors for depression and other common mental …

Single-Case Experimental Designs For Behavioral Neuroscience, Paul L. Soto

Faculty Publications

Single-case experimental designs (SCEDs) are commonly used in behavior analytic research but rarely used in behavioral neuroscience research. The recent development of technologies that allow control of the timing of neurobiological events such as gene expression and neuronal firing enable the fruitful application of SCEDs for the study of brain-behavior relations. There are at least 3 benefits expected from applying SCEDs to study how neurobiological events affect behavior. First, SCEDs entail direct within- and across-subject assessments of reliability, likely increasing the probability of replication across studies and encouraging a search for the causes of replication failure when they occur. Second, …

#Bopo: The Effect Of Body Positive Social Media Content On Women’S Mood And Self-Compassion, Hope R. Rutter, Kaley M. Michael, Brittany J. Repak, Cindy J. Campoverde-Reinoso, Thao Hoang, Kathy R. Berenson

Student Publications

Body positivity is a trending movement that promotes appreciation of one’s body, including acceptance of one’s appearance and perceived flaws. In two experiments, we compared the effects of body-positive social media content relative to idealized body content and neutral control content on young women’s psychological states. In study 1, participants were randomly assigned to view Instagram posts involving fitspiration photos, body positive photos, body positive quotes, or travel landscape photos. In study 2, participants were randomly assigned to view Instagram posts involving selfies of the same individuals’ faces with or without makeup. As predicted, viewing body positive content (body positive …

Al Jinan الجنان

The current study sets up to investigate the psychological and social characteristics among the bribe taker in addition to examining its relationship to some psychological, social and behavioral variables. Accordingly, the researchers have administered a battery of standardized psychometric tests concerning self-concept, mental alienation and psychopathic deviance to a sample of 14 bribe takers among individual prisoners who were condemned for bribery crime in addition to a similar sample of individuals who were not concerned by bribery. Their range age varies from 25 and 65. The results of the study revealed that the bribe taker is characterized by a crude …

Application Of The “Idisco” Full-Brain Tissue Clearing Method: A View Of Dopamine And Inflammation In The Hiv-1 Transgenic Rat, Kristin Nickole Kirchner

Theses and Dissertations

The iDISCO (immunolabeling-enabled three-dimensional imaging of solvent-cleared organs) method is a quick, inexpensive, and easily adaptable tissue staining and clearing procedure that allows neuroscientists to study a protein of interest in a whole, unaltered tissue sample. While the iDISCO method was initially tested and validated for mice embryos and brains, the current experiment sought to adapt the method for use in the rat using HIV-1 transgenic (Tg) rat brain tissue. Antibodies for tyrosine hydroxylase and Iba-1 were validated in the HIV-1 Tg rat and in F344/N control rats using iDISCO. Confocal images were taken of tyrosine hydroxylase positive neurons in …

Wrongful Conviction Documentaries: Influences Of Crime Media Exposure On Mock Juror Decision-Making, Patricia Y. Sanchez

Dissertations, Theses, and Capstone Projects

Psychology and law researchers have urged colleagues to collaborate with the makers of popular media, such as documentary filmmakers, in efforts to educate the general public about wrongful convictions (Kassin, 2017; Wells et al., 2000). Recently, programs depicting wrongful convictions, such as Making a Murderer (Demos & Ricciardi, 2015) and When They See Us (DuVernay, 2019) have garnered substantial viewership. Research on general and case-specific pretrial publicity (Daftary-Kapur et al., 2014; Kovera, 2002) and the effects of crime media (Baskin & Sommers, 2010; Schweitzer & Saks, 2007) demonstrate that although consuming crime-related media and being exposed to information about a …

Predictors Of Social Distancing And Mask-Wearing Behavior: Panel Survey In Seven U.S. States, Plamen Nikolov, Andreas Pape, Ozlem Tonguc, Charlotte Williams

Economics Faculty Scholarship

This paper presents preliminary summary results from a longitudinal study of participants in seven U.S. states during the COVID-19 pandemic. In addition to standard socio-economic characteristics, we collect data on various economic preference parameters: time, risk, and social preferences, and risk perception biases. We pay special attention to predictors that are both important drivers of social distancing and are potentially malleable and susceptible to policy levers. We note three important findings: (1) demographic characteristics exert the largest influence on social distancing measures and mask-wearing, (2) we show that individual risk perception and cognitive biases exert a critical role in influencing …

Assessing Sex Differences In The Effects Of Short-Term Rem Sleep On Anxiety- And Depressive-Like Behaviors In Rats, Nadia Meshkati

Seton Hall University Dissertations and Theses (ETDs)

Findings from both human and animal studies suggest rapid eye movement (REM) sleep disturbances following a traumatic event can lead to inability to extinguish the fear association, and eventually influence the development of post-traumatic stress disorder (PTSD). Additionally, research has demonstrated that sleep disruptions, including REM sleep deprivation (RSD), increases anxiety- and depressive-like behaviors and states in animals and people, with evidence of sex differences. Furthermore, it has yet to be determined whether short-term RSD, a more natural animal model of PTSD, can influence affective state of subjects. The present study applied short-term RSD to investigate sex differences in the …

Using Video Modeling To Teach Staff How To Implement Preference Assessments, Megan Weaver

All Graduate Plan B and other Reports, Spring 1920 to Spring 2023

Identification of reinforcers through preference assessments for individuals with disabilities is an important task because it increases the probability of skill development, including academic tasks, self-help skills, social skills, and behavior modification. Teachers of students with disabilities often experience problems with training paraprofessionals to implement preference assessments using written instructions alone. In this study, researchers will investigate whether video modeling will be more effective than written instruction to staff to implement preference assessments. Participants will include three to five paraprofessionals in a classroom setting with no previous behavior analysis training on preference assessments and three to five students in a …
