Developing Conceptual Understanding And Procedural Fluency In Algebra For High School Students With Intellectual Disability, Andrew J. Wojcik
Developing Conceptual Understanding And Procedural Fluency In Algebra For High School Students With Intellectual Disability, Andrew J. Wojcik
Theses and Dissertations
Teaching students with Intellectual Disability (ID) is a relatively new endeavor. Beginning in 2001 with the passage of the No Child Left Behind Act, the general education curriculum integrated algebra across the K-12 curriculum (Kendall, 2011; National Governors Association Center for Best Practices & Council of Chief State School Officers, 2010), and expansion of the curriculum included five intertwined skills (productive disposition, procedural fluency, strategic competence, adaptive reasoning, and conceptual understanding) (Kilpatrick, Swafford, & Findell, 2001). Researchers are just beginning to explore the potential of students with ID with algebra (Browder, Spooner, Ahlgrim-Delzell, Harris & Wakeman, 2008; Creech-Galloway, Collins, Knight, …
Apoaequorin Differentially Modulates Fear Conditioning In Adult And Aged Rats, Vanessa Ehlers
Apoaequorin Differentially Modulates Fear Conditioning In Adult And Aged Rats, Vanessa Ehlers
Theses and Dissertations
Normal aging is associated with a number of changes in behavioral and cellular function, and is often linked to increased susceptibility to cognitive impairment. The hippocampus has been widely implicated in learning and memory, and many forms of learning that are hippocampus-dependent (e.g. trace fear conditioning) are impaired in aged animals. A proposed contributor to aging-related cognitive impairment is aging-related calcium (Ca2+) dysregulation. This dysregulation is thought to result from changes in specific Ca2+-regulatory mechanisms, including abnormal Ca2+ ion channel activity or expression, as well as reduced Ca2+-binding protein (CaBP) expression, which is associated with cognitive and synaptic impairment. Previous …
A Further Analysis Of Commission Errors During Discrete Trial Training, Tavy Alisa Matthews
A Further Analysis Of Commission Errors During Discrete Trial Training, Tavy Alisa Matthews
Theses and Dissertations
Treatment integrity has been manipulated in various ways to evaluate its impact on intervention effectiveness. Studies have compared different types of integrity failures and levels of treatment integrity in various contexts and behavioral interventions. Evaluations include differential reinforcement of alternative behavior, child compliance, and discrete trial training. However, further research is needed to establish the point at which integrity becomes detrimental to intervention effectiveness. The purpose of this study was to conduct a parametric analysis (i.e., 100%, 75%, 50%, & 25%) of treatment integrity to examine the effects of commission errors during discrete trial training. Three participants, ages 35 - …
Evaluating Computerized Math Performance Using Progressive Ratio Schedules In Children With Attention Deficit Hyperactivity Disorder, Lauren Stroker
Evaluating Computerized Math Performance Using Progressive Ratio Schedules In Children With Attention Deficit Hyperactivity Disorder, Lauren Stroker
Theses and Dissertations
One method of assessing reinforcer strength is to use a progressive ratio (PR) schedule of reinforcement, whereby response requirements to access reinforcers gradually increase. PR schedules have been used to assess reinforcer potency in numerous applications with nonhumans in basic research, children and adults with disabilities, and individuals with histories of substance abuse problems. However, the utility of PR schedules to determine robust reinforcers has not been assessed with children with attention deficit – hyperactivity disorder (ADHD) regarding academic tasks, such as mathematics. The inability to remain on task presents a challenge for teachers in schools, and poses detrimental effects …
The Use Of The Performance Diagnostic Checklist-Human Services To Assess And Improve The Job Performance Of Individuals With Disabilities, Madison Smith
Theses and Dissertations
Employers often do not have the means to identify the specific variables that influence poor work performance, particularly for employees with disabilities. The Performance Diagnostic Checklist-Human Services (PDC-HS) is a tool designed to identify these variables and potential solutions to employee performance problems. Although the PDC-HS has been used with a variety of employees, it has not been examined for use with individuals with disabilities. This study evaluated the effectiveness of the PDC-HS with adults with disabilities in an integrated workforce, to increase the productivity of two employees when required to perform a pricing task. Results showed that the PDC-HS …
Behavioral Economic Analyses Of Reinforcement In The Experimental Analysis Of Human Behavior, James Allen Chastain
Behavioral Economic Analyses Of Reinforcement In The Experimental Analysis Of Human Behavior, James Allen Chastain
Theses and Dissertations
Evidence-based advances in the field of Behavior Analysis have begun to demonstrate ways in which behavioral-economic methods may provide a coherent understanding of responding and consumption of reinforcers. This dissertation extends the literature to behavioral-economic analyses of programmed video reinforcement in the experimental analysis of human behavior (EAHB), as well as a novel reinforcement arrangement for reduction of in-session duration. Three aims served to guide this study: (a) demonstrate the feasibility and utility of behavioral-economic assessments of reinforcement in EAHB, (b) extend economic predictions of unit price to video reinforcement arrangements, and (c) evaluate the utility of an exponential model …
Generalization Across Modalities Of Expressive And Receptive Language Acquisition Through The Use Of Multiple Exemplar Training And Errorless, Melinda Galbato
Generalization Across Modalities Of Expressive And Receptive Language Acquisition Through The Use Of Multiple Exemplar Training And Errorless, Melinda Galbato
Theses and Dissertations
Children with Autism Spectrum Disorder (ASD) tend to display deficits with language acquisition and generalization of language skills after acquisition. Discrete trial teaching (DTT) includes general procedures used to teach language acquisition skills (such as receptive and expressive language) to children with ASD. Multiple exemplar teaching (MET) is a specialized type of DTT that includes multiple discriminative stimuli used during teaching trials, as opposed to only one target during the initial teaching. This present study assessed the efficacy of a general DTT procedure and MET for acquisition and generalization of two modalities of language skills: receptive and expressive. Goals of …
Training A New Trick Using No-Reward Markers: Effects On Dogs’ Performance And Stress Behaviors, Naomi Rotenberg
Training A New Trick Using No-Reward Markers: Effects On Dogs’ Performance And Stress Behaviors, Naomi Rotenberg
Theses and Dissertations
This study explored using no-reward markers (NRMs). Dogs were taught a novel trick. In the IG group dogs’ errors were ignored; in the NRM group they elicited a tone. Performance and stress were evaluated. IG dogs reached higher levels of performance, with no difference in the frequency of stress behaviors.
Functionally Distinct Pools Of Calcineurin Contribute To Depotentiation-Like Synaptic Changes In The Lateral Amygdala During Auditory Fear Extinction, Elena Kay Rotondo
Functionally Distinct Pools Of Calcineurin Contribute To Depotentiation-Like Synaptic Changes In The Lateral Amygdala During Auditory Fear Extinction, Elena Kay Rotondo
Theses and Dissertations
Until recently, auditory fear extinction was not thought to modify substrates involved in the storage of the original auditory fear memory. Evidence now suggests that extinction results in the reversal of the fear conditioning-induced potentiation of thalamic inputs to the lateral amygdala. However, little is known about the molecular mechanisms that support this depotentiation of synaptic strength. Here we present behavioral and molecular evidence in support of the contribution of two distinct pools of the protein phosphatase calcineurin to depotentiation-like changes in lateral amygdala AMPA receptor trafficking during auditory fear extinction. Calcineurin protein that exists prior to the onset of …
Effects Of Reinforcement Duration And Duration-Correlated Stimuli On Preference In Pigeons, Michael James Harman
Effects Of Reinforcement Duration And Duration-Correlated Stimuli On Preference In Pigeons, Michael James Harman
Theses and Dissertations
Pigeons were trained in a two-key, concurrent chains choice procedure with equal initial and terminal links. Across conditions, the durations of reinforcement in the terminal links were either equal (3-s vs 3-s) or unequal (3-s vs 6-s), and these durations were either uncued by hopper lights (both white) or cued (3-s: white; 6-s: colored). The pigeons’ choice responding leading to the longer duration of reinforcement was generally in the range of indifference with nondifferential hopper lights, but favored the longer duration with differential hopper lights. Taken together, the data suggest that differential hopper lights facilitated the discrimination of the longer …
Using Video Modeling To Teach Parents To Use The Natural Language Paradigm, Brittany Ann Leblanc
Using Video Modeling To Teach Parents To Use The Natural Language Paradigm, Brittany Ann Leblanc
Theses and Dissertations
There is paucity of research examining the use of video modeling to train parents to implement formats of early intervention such as Naturalistic Environmental Training (NET). The purpose of the current study was to evaluate the efficacy of video modeling to train parents to implement the Naturalistic Language Paradigm (NLP), a specific format of NET, with their children diagnosed with or suspected of having autism spectrum disorder. All three parents demonstrated accurate performance of the components of NLP with an adult confederate and met the mastery criterion in two or three video modeling sessions. We measured the parent’s accurate implementation …
Comparing Fixed-Amount And Progressive-Amount Schedules Of Reinforcement For Tic Suppression, Matthew Richard Capriotti
Comparing Fixed-Amount And Progressive-Amount Schedules Of Reinforcement For Tic Suppression, Matthew Richard Capriotti
Theses and Dissertations
Chronic tic disorders (CTDs) involve motor and/or vocal tics that cause substantial distress and impairment. Existing behavioral interventions for CTDs have comparable efficacy to pharmacological treatments but still leave many individuals with significant tic symptoms and impairment. One approach to improving existing treatments involves conducting pre-clinical laboratory research to evaluate procedures that may be attractive candidates for applied treatment research. Reinforcing tic suppression via differential reinforcement of other behavior (DRO) procedures produces decreases in tic frequency of ~80% in youth with CTDs; however, a more robust reduction may be needed to affect durable clinical change. The present study compared the …
The Impact Of Relational Training Of Preferred Food And Non-Preferred Food To Arbitrary Symbols On Implicit Relational Tasks, Janelle Antoinette Allison
The Impact Of Relational Training Of Preferred Food And Non-Preferred Food To Arbitrary Symbols On Implicit Relational Tasks, Janelle Antoinette Allison
Theses and Dissertations
The Mixed-Trial Implicit Relational Assessment Procedure (MT-IRAP) is a tool for measuring implicit behavior (i.e., biases or beliefs the individual is unaware of or intends to conceal from the public) among individuals. The MT-IRAP is a modified version of the Implicit Relational Assessment Procedure (IRAP) and was designed to address limitations inherent to the IRAP’s design. The MT-IRAP was tested with adult participants across a series of five studies. Throughout each study, the MTIRAP assessed implicit behavior toward high-preferred foods, non-preferred foods, and arbitrary symbols. The experimenter administered the MT-IRAP before and after participant completion of a task designed to …
Decreasing Bouts Of Prolonged Sitting Among Office Workers, Nicholas Green
Decreasing Bouts Of Prolonged Sitting Among Office Workers, Nicholas Green
Theses and Dissertations
Health care costs of preventable diseases such as cardiovascular disease, type II diabetes, and obesity are higher than ever, and indicate the need for behavioral interventions. Research has shown that individuals who sit for extended periods are at higher risk for these diseases. Moreover, the risks associated with sitting have been found to be independent of an individual’s physical activity. That is, longer durations of sitting per day are associated with higher levels of unwanted health risks, regardless of how often an individual exercises. There is a need to address this issue in today’s inactive workplace. Research indicates that office …

Factors That Predict Incident Reporting Behavior In Certified Registered Nurse Anesthetists, Nicole K. Damico
Theses and Dissertations
Improving patient safety through reduction of medical errors is a national priority. One of the strategies widely utilized to address this issue is the use of incident reporting systems. The purpose of this study was to describe factors that predict the likelihood that Certified Registered Nurse Anesthetists (CRNAs) will use incident reporting systems, guided by the theory of planned behavior (Ajzen, 1991). A non-experimental, correlational research design was utilized to achieve the study aims. Following IRB approval, a cross-sectional survey was administered electronically to a random sample of practicing CRNAs. Correlational analyses and a standard logistic regression were utilized to …

Cyberspace And Real-World Behavioral Relationships: Towards The Application Of Internet Search Queries To Identify Individuals At-Risk For Suicide, Casey C. Miller
Theses and Dissertations
The Internet has become an integral and pervasive aspect of society. Not surprisingly, the growth of ecommerce has led to focused research on identifying relationships between user behavior in cyberspace and the real world - retailers are tracking items customers are viewing and purchasing in order to recommend additional products and to better direct advertising. As the relationship between online search patterns and real-world behavior becomes more understood, the practice is likely to expand to other applications. Indeed, Google Flu Trends has implemented an algorithm that accurately charts the relationship between the number of people searching for flu-related topics on …
Forecasting Effects Of Influence Operations: A Generative Social Science Methodology, Christopher W. Weimer
Forecasting Effects Of Influence Operations: A Generative Social Science Methodology, Christopher W. Weimer
Theses and Dissertations
Simulation enables analysis of social systems that would be difficult or unethical to experiment upon directly. Agent-based models have been used successfully in the field of generative social science to discover parsimonious sets of factors that generate social behavior. This methodology provides an avenue to explore the spread of anti-government sentiment in populations and to compare the effects of potential Military Information Support Operations (MISO) actions. This research develops an agent-based model to investigate factors that affect the growth of rebel uprisings in a notional population. It adds to the civil violence model developed by Epstein (2006) by enabling communication …
Analysis Of Social Network Measures With Respect To Structural Properties Of Networks, Joshua D. Guzman
Analysis Of Social Network Measures With Respect To Structural Properties Of Networks, Joshua D. Guzman
Theses and Dissertations
Social Network Analysis (SNA), the study of social interactions within a group, spans many different fields of study, ranging from psychology to biology to information sciences. Over the past half century, many analysts outside of the social science field have taken SNA concepts and theories and have applied them to an array of networks in the hope of formulating mathematical descriptions of the relations within the network of interest. More than 50 measures of networks have been identified across these fields; however, little research has examined the findings of these measures for possible relationships. This thesis tests a set of …
A Framework For The Measurement Of Simulated Behavior Performance, Christopher M. Cooper
A Framework For The Measurement Of Simulated Behavior Performance, Christopher M. Cooper
Theses and Dissertations
Recent development in video games, simulation, training, and robotics has seen a push for greater visual and behavioral realism. As the reliance on high fidelity models in the education, training, and simulation communities to provide information used for strategic and tactical decisions rises, the importance of accuracy and credibility of simulated behavior increases. Credibility is typically established through verification and validation techniques. Increased interest exists in bringing behavior realism to the same level as the visual. Thus far validation process for behavioral models is unclear. With real world behavior a major goal, this research investigates the validation problem and provides …
The Demographic And Behavioral Patterns Of Visitors To The Usaf Museum, Charlene V. Purtee
The Demographic And Behavioral Patterns Of Visitors To The Usaf Museum, Charlene V. Purtee
Theses and Dissertations
The United States Air Force Museum, located at Wright Patterson AFB, Ohio, provides an overview of the Air Force's aviation history, free to the public. In 1996, the Foundation, a non-profit organization that provides financial support for the display of the aviation memorabilia, attempted to determine the demographic representation of the Foundation membership. In their analysis the Foundation found that the membership represented only a small portion of the actual population that visited the Museum annually. In 1997, a second survey was accomplished to establish a cursory demographic breakout and answer a variety of questions from the visitors at the …
Predicting Fraudulent Behavior: An Examination Of Characteristics Commonly Exhibited By Fraudulent Dod Contractors, Dwayne P. Sellers
Predicting Fraudulent Behavior: An Examination Of Characteristics Commonly Exhibited By Fraudulent Dod Contractors, Dwayne P. Sellers
Theses and Dissertations
This study examines the relationship between company size, slack, return on investment, and the frequency of fraudulent behavior. A model is proposed in which an increase in company size and a decrease in company slack and return on investment would increase the frequency of fraudulent behavior. A test of the model showed strong support between a relationship between company size and incidents of fraudulent behavior. Additionally, the results suggest that levels of slack may contribute to the frequency of fraud. Further tests provide no support for the relationship between the decrease in return on investment and the increase in the …
