Underlying Mechanisms Of Generalized Anxiety Disorder In An Experimental Fear-Conditioning Paradigm, Melissa Hartnell

Theses and Graduate Projects

The purpose of this study was to examine the potential underlying mechanisms of generalized anxiety disorder (GAD) including fear generalization, maladaptive avoidance, and intolerance of uncertainty (IU) in a sample of adults with GAD, as compared to healthy controls in the context of a lab-based fear conditioning paradigm. The current study utilized data from the University of Minnesota ANGST Laboratory’s Danger Zone – Research Domain Criteria (DZ-RDoC) neuroimaging study. Participants consisted of 40 individuals ranging from ages 18-60, with 19 meeting criteria for GAD (M age = 30.57, SD = 11.70) and 21 healthy controls (M age = …

School-Based Consultation To Promote Generalization Of Early Childhood Educators’ Evidence-Based Practices: A Meta-Analysis, Tyler E. Smith, Zachary Charles Labrot, Emily Maxime, Abbigail Lawson

Perspectives on Early Childhood Psychology and Education

Early childhood educators are tasked with supporting young children’s academic, behavioral, and social-emotional through the use of evidence-based practices (EBPs). Unfortunately, early childhood educators may struggle with consistent implementation of EBPs. When this occurs, school-based consultation may be beneficial in promoting early childhood educators’ use of effective classroom management practices and interventions. A critical aspect of school-based consultation is ensuring that early childhood educators generalize strategies they have been trained to use through consultation. However, the extent to which early childhood educators generalize skills trained through consultation across settings, children, and other evidence-based practices is unclear. Therefore, the purpose of …

Towards More Task-Generalized And Explainable Ai Through Psychometrics, Alec Braynen

USF Tampa Graduate Theses and Dissertations

In this work, we propose that adopting the methods, principles, and guidelines of the field of psychometrics can help the Artificial Intelligence (AI) community to build more task-generalizable and explainable AI. Three arguments are presented and explored. These arguments are that psychometrics can help by providing 1) a framework for formulating better datasets, 2) psychometric AI data that can lead to models of generalization in AI, and 3) explainable AI through more informative evaluations.

A review of psychometrics and psychological generalization is performed, along with an overview of evaluation, generalization, and explainability in AI. Various ideas are presented throughout for …

Improved Attending In An 8-Year-Old Boy Diagnosed With Down Syndrome Through Teaching With Acoustical Guidance, Jessica Bracken, Cara Holtz, Benjamin Witts

SCSU Journal of Student Scholarship

Skill acquisition can be particularly difficult when prerequisites are lacking (e.g., attending to learning materials) that are necessary to expand academic abilities. However, behavioral technologies exist that can help individuals overcome, or at least improve their quality of life despite these difficulties. The current case study used a quasi-changing-criterions-design to examine the effectiveness of a Teaching with Acoustical Guidance (TAGteach) technique to increase attending to learning materials in an eight-year-old participant with Down syndrome. The TAGteach technique was effective in increasing the percentage of trials in which the participant looked at materials and the duration of looking at presented materials …

The Roles Of Set Size And Nonexample Type On Concept Formation, Catherine L. Williams, Claire C. St. Peter, Madeleine J. Murphy

Graduate Student Scholarship

Concept formation is demonstrated when a learner responds when new examples are presented (i.e., generalization) but not when new nonexamples are presented (i.e., discrimination). Gradually increasing the number of examples and nonexamples taught together (i.e., set-size expansion) promotes concept formation with nonhumans. Although set size impacts speed of acquisition with humans, concept formation has not been evaluated. Therefore, the primary purpose of the current study was to compare acquisition and concept formation during two procedures: set-size expansion and single set-size. College students were taught two biological concepts, one using set-size expansion and the other with the full …

Musical Instrument Familiarity Affects Statistical Learning Of Tone Sequences., Stephen C Van Hedger, Ingrid Johnsrude, Laura J Batterink

Brain and Mind Institute Researchers' Publications

Most listeners have an implicit understanding of the rules that govern how music unfolds over time. This knowledge is acquired in part through statistical learning, a robust learning mechanism that allows individuals to extract regularities from the environment. However, it is presently unclear how this prior musical knowledge might facilitate or interfere with the learning of novel tone sequences that do not conform to familiar musical rules. In the present experiment, participants listened to novel, statistically structured tone sequences composed of pitch intervals not typically found in Western music. Between participants, the tone sequences either had the timbre of artificial, …

Effects Of Nonexamples On Concept Formation, Catherine Louise Williams

Graduate Theses, Dissertations, and Problem Reports

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 …

Discriminative Stimulus Effects Of Cannabidiol Oil In Rats, Rebecca L. Chalme

Graduate Theses, Dissertations, and Problem Reports

Cannabidiol (CBD) is one of the major centrally active phytocannabinoid components of cannabis, and has been approved by the FDA only for the treatment of two rare seizure disorders. However, CBD has been touted as a potential treatment for anxiety in place of more traditional treatments like benzodiazepines. Although there is some evidence of anxiolytic effects of CBD, its suitability as a substitute for benzodiazepines is unknown. This experiment was designed to assess to what extent CBD shares interoceptive discriminative-stimulus properties with the anxiolytic chlordiazepoxide (CDP), a benzodiazepine. In the present experiment, a range of doses (0-333.3 mg/kg) of over-the-counter …

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

Electronic Theses and 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 …

Stimulus Fading On Teaching Receptive Identification, Dennis Pomorski

Honors Theses

Many of the skills needed to live happily and independently are not in the repertoires of children diagnosed with autism, and they do not learn these skills through exposure to others (MacDuff, 2001). One of the skills children diagnosed with ASD struggle to develop is receptive identification. There is often a risk of prompt dependence or failure to transfer stimulus control to the desired stimuli when using LTM prompting methods. Children with autism spectrum disorder may require a different approach in developing a receptive language repertoire. The purpose of this study was to teach a child diagnosed with ASD receptive …

Using Video-Prompting And Bst To Promote Social Skills In Children With Autism Spectrum Disorder, Alexa Ina

Masters Theses, 2010-2019

The purpose of the present study was to examine the effectiveness of implementing a combined and integrative Behavior Skills Training (BST) and video-prompting paradigm. The training focused on enhancing social interactions and fostering the development of age-appropriate social skills in children diagnosed with Autism Spectrum Disorder (ASD). This package included explicit training for generalization, as a means of fostering skill acquisition across untrained people and settings. Social initiation and reciprocal play are fundamental aspects of sustaining and maintaining relationships therefore, the training focused on teaching these two behaviors. The researcher used a quasi-single subject research design to analyze and measure …

Improving Parent-Child Interactions And Generalized Problem-Solving Skills In Families Of Children With Attention-Deficit/Hyperactivity Disorder Through Adapted Parent Child Interaction Therapy, Carly Bobal

Dissertations, 2014-2019

Attention-Deficit/ Hyperactivity Disorder (ADHD) is the most prevalent parent reported diagnosis among children 3-17 years of age. Parents of children with ADHD often evoke more coercive or negative interactions to help manage their child’s behavior. In addition, they report increased levels of family conflict and higher stress levels, which can place stress on couples and other members within the family system. These interactions may lead to negative reinforcement cycles that maintain or worsen problem behaviors of the child. PCIT is well documented in producing positive outcomes for children with other neurodevelopmental disorders, such as Oppositional Defiant Disorder, Conduct Disorder, or …

Evaluation Of A Wearable Activity Schedule For Promoting Independent Play In Children With Autism Spectrum Disorder, Basak Topcuoglu

Theses and Dissertations

Activity schedules are an antecedent intervention in which a series of visual cues, presented typically in booklets or binders, function as prompts for steps in a behavior chain (e.g., classroom routine, playing hide and seek). Although activity schedules are useful in getting individuals to manage their own behaviors, their typical presentation format can be cumbersome and stigmatizing for children placed in general education classrooms, placing additional barriers for independence and inclusion across environments for these children. Some researchers have used electronic devices such as tablets to display activity schedules, and although more socially acceptable, these are still cumbersome for young …

The Effects Of Reversing Safmeds Presentation On Learning And Generalization, Emily Nordlund

All Master's Theses

Say All Fast Minute Each Day (SAFMEDS) is a flashcard procedure that is effective in producing fluency, but not necessarily generalization, of a content area. One possibility for the lack of generalization is the direction of the SAFMEDS training. Most learners are presented with a definition (the longer side) and have to say the term (the shorter side). Elements of single-case and between-groups designs were used to examine the effects of reversing the direction of training on acquisition and fluency of SAFMEDS content, as well as generalization. Within this study, the control group was presented with a book or paper …

An Evaluation Of Static Versus Dynamic Instructional Stimuli On Generalization Of Action Tacts, Shana Renee Fentress

Theses and Dissertations

Researchers have noted that children with autism have difficulty generalizing responses to stimuli outside of those used in training. Some studies have analyzed ways to promote generalization such as using concurrent training or using stimuli that would be most similar to those found in the natural environment. Little research, however, has investigated strategies for promoting generalization of action tacts. The current study investigated two different types of stimulus delivery forms: static (i.e., pictures), which are typically used during instruction, and dynamic (i.e., videos), which may provide stimulation closer to that which a child would encounter in a natural setting. Findings …

Investigating Generalization Of Motorist Yielding To The Gateway Prompt From The Treated Leg Of The Intersection To The Untreated Adjacent Leg, Brian J. Crowley-Koch

Dissertations

Pedestrian safety continues to be an important research topic, especially since recent data show a small increase in pedestrian fatalities (USGAO, 2015). There have been several interventions that prompt pedestrians, but especially motorists, to yield properly at uncontrolled crosswalks (Van Houten, 1988; Van Houten & Malenfant, 1992; Nasar, 2003; Crowley-Koch, Van Houten & Lim, 2008). One low-cost intervention that has been successful is the R1-6 in road yielding sign (Kannel, Souleyrette, & Tenges, 2003). When this sign is laid out purposefully across a crosswalk (called a gateway), it has resulted in substantial increases in yielding compared to baseline conditions. In …

Semantic Memory, Eiling Yee, Michael N. Jones, Ken Mcrae

Psychology Publications

How is it that we know what a dog and a tree are, or, for that matter, what knowledge is? Our semantic memory consists of knowledge about the world, including concepts, facts and beliefs. This knowledge is essential for recognizing entities and objects, and for making inferences and predictions about the world. In essence, our semantic knowledge determines how we understand and interact with the world around us. In this chapter, we examine semantic memory from cognitive, sensorimotor, cognitive neuroscientific, and computational perspectives. We consider the cognitive and neural processes (and biases) that allow people to learn and represent concepts, …

Generalization Of Ipad®-Learned Skills In Children With Autism Spectrum Disorder, Claire Klein

CMC Senior Theses

The present study investigated the effects of learning from an iPad® to real-world skills for children with autism spectrum disorder (ASD). Research has demonstrated that for some children with ASD, electronic media such as an iPad® is highly motivating, highly preferred, and increasing in popularity in homes and in classrooms (Chen & Bernard-Opitz, 1993; Rideout, 2017; Shane & Albert, 2008). Because academic skills are often difficult for children with ASD due to problems with motivation, the current study used the motivating features of iPad® apps to teach real-world academic skills to children with ASD, with the hypothesis that skills would …

Generalization Of Social Skills Based On Instructional Setting, Monica St.Amand - Santos

Walden Dissertations and Doctoral Studies

Children with social skills deficits in verbal and nonverbal communication can face a variety of social challenges in many aspects of their lives. Given the increasing social needs of many students in today's classrooms, there is a need for increased social skills instruction and support in public schools. Inclusion opportunities in public schools can have a positive impact on the development of social skills and can increase peer understanding and empathy for students with special needs. Although there is research in the area of inclusion and its benefits, there is little known about the impact of the instructional setting on …

A Translational Evaluation Of Renewal Of Inappropriate Mealtime Behavior, Vivian Ibañez, Cathleen C. Piazza, Kathryn M. Peterson

Theses & Dissertations

The term renewal describes the recurrence of previously extinguished behavior that occurs when the intervention context changes. Renewal has important clinical relevance as a paradigm for studying treatment relapse because context changes are necessary for generalization and maintenance of most intervention outcomes (Podlesnik, Kelley, Jimenez-Gomez, & Bouton, 2017). The effect of context changes are particularly important during intervention for children with feeding disorders because children eat in a variety of contexts, and extinction is an empirically supported and often necessary intervention. Therefore, we used an ABA arrangement to test for renewal during intervention with 3 children diagnosed with a feeding …

Feedback Delivery Timing & Behavior Skills Training: Training University Students To Perform Dtt, Matthew Taylor

Masters Theses, 2010-2019

Behavior Skills Training (BST) has been a common, efficient, and successful training strategy for teaching individuals to perform discrete trial teaching (DTT) although there is not much established information about the separate effects of its training components. Research on modeling and feedback alone as well as within BST, however, suggest that they may be the most significant contributors towards producing behavior change along with the regular recommendation that feedback is best delivered immediately after the occurrence of target behavior for reinforcement. Yet studies that have employed feedback before the occurrence of target behavior have observed no adverse or detrimental effects …

Sleep-Based Memory Processing Facilitates Grammatical Generalization: Evidence From Targeted Memory Reactivation., Laura J Batterink, Ken A Paller

Brain and Mind Institute Researchers' Publications

Generalization-the ability to abstract regularities from specific examples and apply them to novel instances-is an essential component of language acquisition. Generalization not only depends on exposure to input during wake, but may also improve offline during sleep. Here we examined whether targeted memory reactivation during sleep can influence grammatical generalization. Participants gradually acquired the grammatical rules of an artificial language through an interactive learning procedure. Then, phrases from the language (experimental group) or stimuli from an unrelated task (control group) were covertly presented during an afternoon nap. Compared to control participants, participants re-exposed to the language during sleep showed larger …

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 …

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 …

Initiating Conversation By A Kindergarten-Aged Child With Autism Spectrum Disorder, Eliana A. Segal

Senior Honors Projects, 2010-2019

Children with Autism Spectrum Disorder (ASD) have social skill deficits that are often manifested in a failure to achieve normal back-and-forth conversation. They rarely initiate social interactions and often show little responsiveness to others. This can extinguish the social initiations of their peers, leading to great difficulty making friends. The purpose of the present study was to teach a child with ASD at an inter-professional autism clinic how to initiate and reciprocate a social conversation. A prompt fading procedure was implemented during training sessions to build a set of social skills into the child’s repertoire. The intervention provided social attention …

Parent-Child Interaction Therapy Informed By Applied Behavior Analysis For Developmental Delay: Parent And Sibling Coaching With Setting Generalization, Mariel S. Cannady

Dissertations, 2014-2019

Parent-Child Interaction Therapy (PCIT) is a well-established, empirically-supported treatment for young children with disruptive behaviors. PCIT was initially designed for treatment of typically-developing children with oppositional and disruptive behaviors. There is emerging support for PCIT as a treatment for behavior challenges seen in children with developmental delays. However, some modifications may be needed to respond to the severity of delay, parent treatment goals, and the function of the challenging behavior. Using a non-concurrent multiple-baseline experimental design, the current study examined the effectiveness of a modified PCIT approach for a preschool child with global developmental delay and co-occurring behavior problems. Modifications …

Generalization Of Joint Attention: Using Parent Child Interaction Therapy To Program Social Skills In Children With Developmental Disorders, Thomas E. Rigg

Masters Theses, 2010-2019

Generalization of social behaviors is a vital component of human behavior. Children with Autism Spectrum Disorder often show symptomology that includes impairment in social behavior and failure to generalize behavior on the whole. Initiation of joint attention is a social behavior that can be understood as a behavior cusp and worthy of intervention to promote development. Parent-Child Interaction Therapy has been studied in recent years for its efficacy in treating some dimensions of Autism Spectrum Disorder in children and adolescence. The current study sought to explore the efficacy of Parent-Child Interaction Therapy in promoting the generalization of initiation of joint …

Exploring Barriers To The Generalization Of Social Skills Interventions For Children Diagnosed With Asd: A Qualitative Analysis Of ‘Youth Engagement Through Intervention’, Zachary Shindorf

Graduate Student Theses, Dissertations, & Professional Papers

Many children who are diagnosed with Autism Spectrum Disorder (ASD) have difficulty with social skills and maintaining friendships. In turn, many social skills interventions have been developed to aid in the treatment of children diagnosed with ASD. Children with ASD, however, have difficulty generalizing the skills learned in social skills interventions to more natural settings like the home and school. This study, therefore, explored the barriers to the generalization of a social skills intervention, Youth Engagement Through Intervention (YETI) for children with ASD. Barriers to the generalization of YETI were explored through the qualitative examination of parents’ acceptability of the …

An Individualized Approach To Teach Greeting And Conversation Skills With Persons With Autism: Efficacy, Generalization, And Social Acceptability Outcomes, Stephanie A. Hood

Theses & Dissertations

Individuals with an autism spectrum disorder commonly exhibit deficits in social skills, which can lead to a lack of friendships (Howlin, 2003) and underemployment (Shattuck et al., 2012). We selected social skills based on a parent interview and a direct assessment of three individuals’ conversation and greeting deficits. We taught the conversation and greeting skills using behavioral skills training and within-session prompting. We assessed generalization of the conversation and greeting skills across unfamiliar conversation partners and maintenance over time. We obtained parent responses on the social acceptability of their child’s social skills. A multiple baseline design across behaviors was used …
