The Effects Of A Picture Acitivty Schedule And Functional Communication Training, Sarah J. Lett

Honors Theses

The purpose of this study is to investigate the effects a package treatment containing a picture activity schedule and functional communication training on the reduction of problem behaviors on a child with developmental delays. The study was conducted by first establishing discrimination between pictures, to be used in the picture activity schedule. Then the tutors progressively advanced through the six phases of the picture activity schedule. Each phase taught fundamental rules such as “first this, then that”, and built the schedule to more complex structure. In this way, the student could anticipate upcoming tasks, and preferred activities. The predictor strategy …

Simple Visual Discrimination Training For A Child With Autism And Exceptional Learning Difficulties, Rachel Burroughs

Honors Theses

One of the most basic pre-requisite skills for learning is simple visual discrimination. Unfortunately, the literature is lacking in how to teach simple visual discrimination to children with difficulty learning. To address this problem, the current study set out to teach a child with autism, and exceptional learning difficulty, simple visual discrimination. To do this, the researchers used a simple reversal design using a prompt fading strategy. To shape the independent behavior of selecting the correct stimulus in the presence of two other stimuli, the researchers started by reinforcing touching the stimuli when there were no other distractor stimuli present, …

The Combined Effects Of Picture Activity Schedules And Extinction Plus Differential Reinforcement On Problem Behavior During Transitions, Jessica Hurdelbrink

Honors Theses

To decrease problem behaviors and increase compliance during transitions, a treatment package consisting of a picture activity schedule combined with extinction and differential reinforcement of other behavior was implemented. The study consisted of baseline and the intervention. Based on previous studies involving picture activity schedules, Gina Cross wrote the protocol for the teaching of the activity schedule and the transition protocol. The teaching protocol was made up of four stages of most-to-least prompting, and involved teaching the child to move the picture icon to the bottom of the schedule independently. The transition protocol gave instructions on how the tutor and …

Gradual Guidance And Independent Activity Schedules For Children With Autism, Amanda Driscoll

Honors Theses

The goal of this intervention was to increase on-task and on-schedule behavior in a child with autism through the use of gradual guidance and an independent activity schedule. The participant was a three year-old boy who exhibited noncompliant problem behavior. He was at mastery level for the tasks that were included in the independent activity schedule and had no prior learning experience with an independent activity schedule. Gradual guidance was used to decrease the time it took for him to learn the complex behavior that is involved with an independent activity schedule and to keep the participant on-task and on-schedule …

Delayed Match-To-Sample In Preschool Children, Thomas Ratkos

Masters Theses

In delayed match-to-sample (DMTS) tasks, a sample stimulus is shown and then removed for some period of time before comparison stimuli are presented. Joint control theory (Lowenkron, 1984, 1988, 1991, 1998, 2006) explains correct selections on delayed match-to-sample tasks in terms of the joint control of behavior by the comparison stimulus and a repeated word or words originating from the sample stimulus. Eight children ages 3 to 6 were exposed to a DMTS task with visual stimuli using a 15s delay. During training, children were taught to name the stimulus cards and then repeat the name of the target stimulus …

Impulsive Choice In Unmedicated And Medicated Children Diagnosed With Adhd: Examining The Variables Of Reward Type And Adhd Subtype, Nicole Henriksen

Dissertations

Developmentally inappropriate and impairing impulsive behaviors are often seen in attention-deficit/hyperactivity disorder (ADHD). One method for objectively assessing impulsivity is the Choice-Delay Task (C-DT) which presents repeated opportunities to choose between a smaller, sooner (SS) or larger, later (LL) reward. A preference for the SS reward that results in less total reward is considered impulsive. Many studies have found that participants diagnosed with ADHD choose the SS reward more than typical controls. However, less is known about the effects of different types of rewards, or the comparative performance of certain subgroups, such as children diagnosed with ADHD Predominantly Inattentive Type …

Evaluation Of The Efficacy Of A Rat Agreement Based Reinforcement Procedure, Katherine B. Lalonde

Masters Theses

Since 2007, giant African pouched rats (Cricetomys gambianus) have been used successfullyfor detecting Tuberculosis (TB) positive patients.The rats are trained to detect TB-positive sputum samples through the use of operant conditioning techniques, in which an indicator response is rewarded with food. If the rats are to be used for first line screening of patients reinforcement could not be provided because the true status of the sample would be unknown. The present study evaluated the effects of a reinforcement-for-agreement procedure that could be used to reinforce indication responses when the true status of the sample is unknown. Four rats evaluated 100 …

Influences Of Tnt-Food Pairings On The Performance Of Mine Detection Rats In Early Training Stages, Timothy L. Edwards

Dissertations

Anti-Persoonsmijnen Ontmijnende Product Ontwikkeling (APOPO), a Belgian nongovernmental organization headquartered in Tanzania, trains giant African pouched rats (Cricetomys gambianus) to detect land mines and deploys the rats for operational use in countries afflicted with mines and explosive remnants of war. In the present study an evaluation of the influence of ongoing scent-food pairings on the performance of the rats in early mine detection training was conducted. Twenty young rats in APOPO’s mine detection rat program were divided into two groups and exposed to five daily stimulus-food pairing sessions each week. For the experimental group the stimulus was the …

Sharing: Social Behavior In Situations Of Risk, Stephanie Theresia Stilling

Dissertations

The present study will experimentally investigate human cooperation (sharing) in a laboratory foraging task that simulates environmental variability and resource scarcity (shortfall risk). Specifically, it investigates whether a risk-reduction model of sharing developed by evolutionary biologists (derived from a risk-sensitive optimization model known as the energy-budget rule) could predict human cooperative behavior. Participants respond to earn points exchangeable for money when point gains were unpredictable. Failures to acquire sufficient points result in a loss of accumulated earnings (a shortfall). Participants are given the choice between working alone or working with others. The difficulty of meeting the earnings requirement is manipulated …

Computerized Behavioral Activation Treatment For Major Depressive Disorder And The Effects On Sexual Desire, Anthony G. Bonita

Dissertations

The present study was designed to examine the effects of a computerized behavioral activation treatment program on sexual desire, sexual behavior, and depression symptoms. Seven adults who met criteria for either major depressive disorder or dysthymic disorder were recruited from Kalamazoo, Portage, and surrounding areas in Southwestern Michigan. All participants completed at least five sessions of behavioral activation treatment, and six out of seven participants completed all ten sessions. Symptoms of depression, sexual desire, and sexual behavior were assessed at pretreatment and before each treatment session through a combination of the Beck Depression Inventory – II (BDI-II), the Revised Hamilton …

Use Of A Gateway In-Street Sign Treatment To Increase Yielding To Pedestrians At Crosswalks, Miles K. Bennett

Masters Theses

An important goal to reduce the number of collisions between motorists and pedestrians is to increase motorist’s yielding right-of-way to pedestrians in crosswalks. The current study addresses this goal. A Gateway installation of instreet signs (one in-street sign installed between the two travel lanes in each direction and one on both edges of the roadway in each direction) was evaluated on multilane roads. The first experiment compared the efficacy of adding multiple in-street signs used in a gateway configuration with a single sign between the two travel lanes in each direction. The second experiment compared the in-street sign gateway treatment …

The Effects Of Preprinted Versus Handwritten Safmeds On Fluency, Samantha Fodrocy

Honors Theses

Precision Teaching is an instructional evaluation technique used by educators to ensure that targeted skills are being achieved by learners (Moran & Malott, 2004). Say all fast a minute each day shuffled (SAFMEDS) is a specific PT influenced instructional strategy intended to develop fluency within timed trials (Eshleman, 2000). However, there is little empirical research related to the proposed effects of SAFMEDS. A recent study by Meindl and colleagues (in press) demonstrated the position of the text on SAFMEDS affected fluency. Results of this study suggest extraneous variables affect responding indicating a possible stimulus control issue. However, there were methodological …

Using Environmental Sounds To Initiate Receptive Language Training For Children With Autism, Woan Tian Chow

Dissertations

A pre-test showed that three pre-school children with autism had difficulty learning to match spoken words to objects (receptive identification). Therefore, they were first taught to match environmental sounds to objects (e.g., to touch a tambourine, when they heard the sound of the tambourine) and then to match spoken words to other objects while continuing to match the mastered environmental sounds to the original objects.

For all three children, simply learning the environmental-sound/object matching did not facilitate learning spoken-word/object matching; however intermixing the training of spoken-word/object matching with the previously mastered environmentalsound/ object matching did result in the mastery of …

Evaluating The Effects Of Camera Perspective In Video Modelingfor Children With Autism: Point Of View Versus Scene Modeling, Courtney Cotter

Dissertations

Video modeling has been used effectively to teach a variety of skills to children with autism. This body of literature is characterized by a variety of procedural variations including the characteristics of the video model (e.g., self vs. other, adult vs. peer). Traditionally, most video models have been filmed using third person perspective (i.e., scene models), where the viewer is watching the actor perform in a scene. Recently, studies have successfully incorporated the use of first person perspective into video models (i.e., point of view models), where the view is directly from the actor's point of view. Currently, no studies …

Testing The Effectiveness Of An Interactive Multimedia System To Train Clinicians In Behavioral Activation, Suzanne E. Decker

Dissertations

Although many treatments for mental health disorders have been found to be effective in research, community clinicians may not receive training in such empirically supported treatments, and therefore, individuals suffering from disorders may not have access to empirically supported treatment in the community. This study examined the use of an interactive multi-media computerized therapy program, Building a Meaningful Life through Behavioral Activation, as a training tool for mental health clinicians (N=21) using a pre-post study design. Participating clinicians were invited to complete this computer program over the course of several weeks, and to complete knowledge quizzes and written responses …

Trial And Error, Delayed Prompting, And Reinforcement Of Prompted Responses In Teaching Receptive Identification Of Pictures, Kristen Lynn Gaisford

Dissertations

Three strategies to train receptive identification of pictures were compared: (a) trial and error, (b) delayed finger-point prompt followed by a reinforcer, and (c) delayed finger-point prompt followed by the spoken word, "good". These three strategies were compared using a multi-element design, assessing the performance of four children, ranging from two to four years of age, selected from a classroom that provides services to children with Early Childhood Developmental Delays (ECDD). Two children mastered the receptive identification of pictures at the same rate regardless of the strategy. For the remaining two participants, the rate of mastery was the same for …

Training The Execution Of Single-Case Research Methodology Skills In An Early And Intensive Behavioral Intervention Setting, Jessa R. Love

Dissertations

Early and intensive behavioral intervention (EIBI) for children with autism is a fruitful area for conducting research on clinically relevant problems in an attempt to investigate some of the unanswered questions about which procedures are most effective and efficient. Unfortunately, it is unlikely that therapists providing these services have received adequate training in conducting relevant single-case design research in this area. Providing such therapists with the skills needed to implement single-case design research protocols could improve the use of the scientist-practitioner model in these settings and greatly expand the base of scientific knowledge in the area.

Behavioral Skills Training (BST; …

An Evaluation Of Preference For Modeling Interventions, Kaneen B. Geiger

Masters Theses

Video modeling is an instructional technique demonstrated to effectively increase social skills, academic skills, daily living skills and play skills of children with autism. There are several hypotheses for why video modeling is effective. One hypothesis is that children with autism prefer watching videos to looking at people, thereby enhancing motivation and making attending to the video model automatically reinforcing, however, preference for video has not been experimentally examined. This study assessed participants' preference for either video modeling or in vivo modeling using a concurrent-chains arrangement. None of the three participants showed a preference for either video modeling or in …

Evaluation Of A Progressive Model For Identifying Preferred Stimuli For Children With Developmental Disabilities, Amanda M. Karsten

Dissertations

Preference assessments for individuals with disabilities differ along many dimensions, including time requirements for implementation and probability of identifying a hierarchy of relative preferences. Some methods of assessment are also more conducive to use with individuals who exhibit problem behavior or certain prerequisite skills. Inaccurate results and loss of valuable treatment time are among the risks associated with selecting ineffective or unnecessarily lengthy procedures. The purpose of the current investigation was to evaluate a progressive model for conducting preference assessments which incorporates many of the aforementioned considerations. Concurrent-operant reinforcer evaluations were used to verify assessment findings. Based on 17 participants …

Using Virtual Reality Enhanced Behavioral Skills Training To Teach Street-Crossing Skills To Children And Adolescents With Autism Spectrum Disorders, Tina R. Goldsmith

Dissertations

Children with Autism Spectrum Disorders (ASDs) often have poor safety skills due to their insensitivity to subtle environmental cues and poor problem solving in the face of stressful tasks. These skill deficits threaten their physical well-being and limit their personal independence. An effective intervention model for teaching safety skills is behavioral skills training (BST). The effects of this 4-part intervention, which includes Instructions, Modeling, Rehearsal, and Feedback, improve with the addition of in situ training. However, creating realistic, safe, and logistically feasible contexts for rehearsal of skills may prove difficult, if not impossible. Virtual reality (VR) may present a solution. …

A Comparison Of Maintenance-Training Methods For Children Diagnosed With Autism, Nicholas L. Weatherly

Dissertations

The current study evaluated the effects of two different maintenance-training methods and one control condition on skill maintenance within a public-school classroom for children diagnosed with autism. The two training methods involved the use of either a continuous-reinforcement schedule or a thinned partial-reinforcement schedule during 20 overlearning training sessions following skill acquisition. The control condition did not involve any overlearning following skill acquisition. Three children were each taught two curricular programs, with each program involving the two training methods and the control condition using a multielement design. Overlearning using a thinned partial-reinforcement schedule reliably produced greater maintenance across all participants, …

Identifying The Most Effective Stimulus To Promote Wayfinding In Elders With Dementia, Allison A. Jay

Masters Theses

When nursing home residents with dementia experience difficulty locating their bedroom, it can create problems for other residents and staff. This study investigated the ability of four elders with severe dementia to recognize various self-referent stimuli (i.e., young adulthood photograph, middle adulthood photograph, current photograph, and printed name). Two of the three participants who were able to complete the assessment recognized their photographs from earlier in life and their printed names but were not able to recognize their current photograph. These two residents then participated in an intervention in which the recognized stimuli were posted outside their bedroom doorway during …

Generalization Of Mands For Information Across Establishing Operations, Sarah A. Lechago

Masters Theses

This study sought to extend the developing literature on teaching mands for information by systematically assessing whether they generalize across different EOs. Three children with autism were taught to perform multiple behavior chains, three of which included a common response topography (e.g., "Where is the spoon?") used for different purposes. An interrupted-behavior-chain procedure was used to contrive the EO for each mand. After a mand for information was taught under one EO, the remaining chains were interrupted to determine whether the mand had generalized across EOs. For all three participants, mands for information generalized across EOs. For one participants, a …

Neuropsychopharmacological Investigations Of Mdma/Cocaine Combinations, John J. Panos

Masters Theses

Despite the popularity of polydrug abuse among recreational MDMA users, relatively few controlled experimental studies have documented the neurobehavioral effects of MDMA in combination with other abused substances. In this study, the neurochemical and behavioral effects of MD MA/cocaine combinations were assessed using in vivo microdialysis with simultaneous measurement of locomotor activity (LMA). Rats were administered cocaine (10 mg/kg or 20 mg/kg, IP), MDMA (1.5 mg/kg or 3.0 mg/kg, IP) or combinations of cocaine and MDMA during microdialysis experiments. Microdialysis samples were collected every 30 min for three hours prior to drug injections. Following drug administration, six additional 30 min …

Effects Of Subchronic Dietary Lead Exposure On Dmtp And Dnmtp Performance In Fisher 344 Rats, Joshua D. Vardigan

Masters Theses

Recent attention has focused on the possibility that even low-level Pb exposure can produce subtle neurological impairments in the absence of overt signs of toxicity. Previous behavioral assessments of learning and memory using DMTS procedures have documented learning impairments in monkeys exposed to Pb during early postnatal development, and although a variety of operant behavioral assays have documented detrimental effects of dietary Pb treatment in rats, the DMTS procedure has not been examined in rats following short-term low levels of Pb through dietary exposure. Thus, the objective of this study was to measure the degree of cognitive impairment produced by …

Evaluation Of An Outpatient Training Service For Children With Autism Spectrum Disorders And Their Families, Britt Winter

Masters Theses

Autism spectrum disorders have a substantial impact on the lives of families and can result in a variety of enrichments to the family environment as well as certain specific stressors (Hecimovic & Gregory, 2005; Tidmarsh & Volkmar, 2003). One service that has proven effective for treatment of individuals with autism spectrum disorders as well as improvement in family dynamics is parent training (Schreibman, 1988). The current study examined 46 individual client files from an outpatient parent training clinic serving children with autism spectrum disorders. Parents were taught to implement interventions for skill acquisition with their children using a behavioral skills …

Functional Assessment Of Problem Behavior In Children With Autism Spectrum Disorders: A Review Of 32 Cases, Jessa R. Love

Masters Theses

The prevalence of autism spectrum disorders among children aged 4 to 17 years is approximately 5.5 to 5.7 out of 1000 children (Centers for Disease Control, 2006). It is not uncommon for children with these disorders to display a wide range of problem behavior (e.g., Farrar-Schneider, 1992; Oswald et al., 1992). While a number of studies have reported aggregated data on the reinforcement functions of such problem behavior, none have reported the distribution of functions with a sample comprised solely of individuals on the autism spectrum. Thus, the purpose of this study was to examine individual client data from an …

Behavioral Tolerance Under Variable Ratio Schedules Of Reinforcement, Barry Eshkol Adelman

Dissertations

Previous studies (e.g., Hoffman, Branch, & Sizemore, 1987) have demonstrated that greater drug tolerance develops in responding under fixed-ratio (FR) schedules of reinforcement when the schedule parameter is small than when it is large; little research has been done on related schedules such as variable-ratio (VR). In Experiment 1, three pigeons responded under a multiple FR 5 FR 125 VR 5 VR 125. A range of prechronic doses of cocaine produced dose-dependent reductions in response rates under the component schedules. Following chronic dosing with daily administrations of 5.6 mg/kg, similar dose-response curves were derived by substitutions of the usual dose. …

Evaluating Increasing And Decreasing Prompt Hierarchies With Developmentally Disabled Adults, Sophie Rubin

Masters Theses

Individuals with developmental disabilities were taught conditional discriminations in the form of an auditory visual matching to sample task using two teaching strategies: the increasing prompt hierarchy and the decreasing prompt hierarchy. A multielement design was used to compare these prompt hierarchies in terms of accuracy, rate of acquisition, number of errors, number of edible reinforcers, and number of praise statements delivered. The results indicate that the increasing prompt hierarchy consistently resulted in an increased number of steps, errors, edibles, and praise statements compared to the decreasing prompt hierarchy. However, differing results were obtained on the accuracy measure across participants. …

Pyramidal Staff Training: Teaching Play And Manding To Children With Autism And Developmental Disabilities, Koji Takeshima

Dissertations

This study involved pyramidal staff training and the teaching of play and manding to children with autism and developmental disabilities in an early intervention program. The following training components were sequentially introduced to each technician: (a) a written procedure; (b) video modeling; (c) a slide show and checklist, combined with video modeling; and (d) feedback. The trainees improved their skills in teaching play as these training components were introduced, and the children's performance in play and manding subsequently improved. For the skills of teaching play, the core component of the training that resulted in the largest improvement varied across technicians. …
