Oral Syringe Training Animals: Indiscriminable and Discriminable Punishment Contingencies

Oral Syringe Training Animals: Indiscriminable and Discriminable Punishment Contingencies

Date: May 2013
Creator: Erickson, Emilie Jane
Description: Animals are commonly trained to perform behaviors during routine husbandry procedures. However, some husbandry procedures have aversive consequences when the real procedure is performed. This commonly results in loss of the trained behavior. The present study assessed whether maintaining the antecedent environmental stimulus conditions between appetitive and aversive outcomes would prevent this effect and, conversely, whether adding a stimulus discrepancy would facilitate this effect. Three domestic rats served as participants in a multiple baseline across participants design with multi-element components. All three rats stopped performing a trained behavior when a discrepant stimulus reliably predicted an aversive outcome. In addition, all three rats continued to perform the same behavior when antecedent environmental stimulus conditions were consistent between aversive and appetitive outcomes. Results are discussed in terms of practical implications for behavior change agents and conceptual implications for learning theory.

Order effects of variability-contingent and variability-independent point delivery: Effects on operant variability and target sequence acquisition.

Order effects of variability-contingent and variability-independent point delivery: Effects on operant variability and target sequence acquisition.

Date: May 2004
Creator: Lee, Coral Em
Description: Previous research has shown that variability is a reinforceable dimension of operant behavior. Additionally, it has been demonstrated that learning is facilitated when variability in responding is high. In this research, variability was observed within an operant composed of any sequence of six left and right key presses. Variability was either a requirement for point delivery (VAR conditions) or points were delivered independent of variability (ANY conditions). Two groups of college undergraduates experienced different orders of conditions. One group began the experiment under VAR conditions, and the variability requirement was later removed. The other group began the experiment under ANY conditions, and the variability requirement was later added. A concurrently reinforced target sequence (i.e., an always-reinforced sequence of left and right key presses) was introduced to both groups after these orders of conditions had been experienced. A variety of outcomes resulted. Subjects learned the target sequence when variability was both high and low with non-target points concurrently available. Other subjects learned the target sequence after all non-target point deliveries had been suspended. One subject failed to acquire the target sequence at all. These results were compared to previous findings and possible explanations for the discrepancies were suggested.

A parametric analysis of the immediate and subsequent effects of response restriction on hand mouthing.

A parametric analysis of the immediate and subsequent effects of response restriction on hand mouthing.

Access: Use of this item is restricted to the UNT Community.
Date: May 2003
Creator: Soderlund, Michael J.
Description: The immediate and subsequent effects of different durations of response restriction were evaluated in a multiple schedule design. Response restriction components of 15, 30, and 60 minutes were conducted between 15 minute alone components. Levels of responding subsequent to the termination of response restriction procedures were compared to free operant levels prior to the implementation of response restriction. Responding during response restriction components reduced to near zero levels. Subsequent levels of responding were similar to or exceeded free operant baseline levels. Results are discussed in terms of potential operant mechanisms responsible for levels of responding subsequent to response restriction.

Parent-Toddler Training:  The Merits of Further Analysis

Parent-Toddler Training: The Merits of Further Analysis

Date: May 2011
Creator: Cermak, Samantha Marie
Description: Earlier identification of autism allows for interventions to begin during toddlerhood. Literature suggests that parents are an important part of very early intervention and specific goals have indicated that they are important to progress. The use of telemedicine may increase access to interventions. The purpose of the study was to evaluate a parent-toddler training program that targeted social-communication skills and incorporated a telemedicine component. Measures included parent teaching targets, child attending, vocal requesting, and coordinated joint attention and the parent's response to coordinated joint attention. Results indicate that parent teaching increased, child attending and vocalizations increased, child coordinated joint attention increased, and the parent's response to coordinated joint attention was primarily social in nature. Analysis of the home observations indicates that direct in home observations or teleconference observations neither under or overestimated behaviors. The results are discussed in the context of teaching and feedback delivery and selection of teaching targets.

Performance Improvement in an Accounting Firm: Comparing Operational and Financial Data Before and After Process Redesign

Performance Improvement in an Accounting Firm: Comparing Operational and Financial Data Before and After Process Redesign

Date: December 2000
Creator: Chhabra, Meeta Kaur
Description: The case study described in this thesis involves a process improvement project in the Tax Department of a Certified Public Accounting firm. A process map was created by interviewing employees involved in the process. A process analysis identified problems and possible solutions. The Partners in the firm decided to streamline the process for simple tax returns in order to make them more profitable. This study examined what impact, if any, the process improvement intervention had on key financial and operational measures. Results indicated that the tax returns prepared in the new process were faster, cheaper, and more profitable. This study indicates that organizations conducting process improvement interventions can beneficially affect key financial and operational measures.

Physiological Effects of Monetary Consequences

Physiological Effects of Monetary Consequences

Date: May 1998
Creator: Kessler, Jeffrey C. (Jeffrey Charles)
Description: Electrodermal responding (EDR) and heart rate (HR) were assessed for seven subjects participating in a reaction time task consequated with monetary bonuses (250, 100, and 10), monetary penalties (250,100, and 10), and a monetary neutral value (00). Unlike previous research employing group designs and a tonic measure (i.e., mean over long periods of time), this study utilized a single-subject design and a phasic measure (i.e., mean over 2-s intervals). Heart rate data was too variable for meaningful analysis. EDR data showed that the peak levels of EDR were higher for penalties than for the corresponding values of bonuses (e.g., -250 vs. +250) for most subjects. Similarly, peak levels of EDR were generally higher during sessions in which consequences were presented than in sessions during which consequences were absent.

The Power of One Reinforcer

The Power of One Reinforcer

Date: August 2013
Creator: Hunter, Mary E.
Description: Animal trainers use shaping to teach many behaviors. However, during shaping, the organism may engage in behaviors other than the target behavior or approximations to the target behavior. If the animal is engaged in other behaviors, the rate of reinforcement may decrease and the trainer may resort to what is sometimes referred to as a “desperation click.” That is, the trainer delivers one reinforcer for a behavior that is not a successive approximation to the target response. Anecdotal reports from trainers suggest that sometimes the animal continues to repeat this other behavior that received only one reinforcer, even in the absence of further reinforcement for that behavior. This study compared whether, during a one minute extinction period, participants spent more time engaged in a behavior that had been reinforced only once after a brief period of no reinforcement or in a behavior that had been reinforced multiple times. Participants, who were university students, played a tabletop game that involved touching and manipulating small objects. Five conditions were repeated twice for each participant: reinforcement for interacting with a training object alone, reinforcement for interacting with a training object with other objects present, reinforcement for interacting with a target object, one reinforcer ...

A Preliminary Analysis of Interactions Between Sibling training and Toy Preferences

A Preliminary Analysis of Interactions Between Sibling training and Toy Preferences

Date: May 2011
Creator: Greer, Julie Winn
Description: Siblings of children who have been diagnosed with autism can play important roles in the lives of their brothers or sisters. Previous literature shows that siblings can effectively change behavior and can increase play interactions. Furthermore, the use of preferred materials may enhance social interactions between the siblings. The purpose of this study was to determine, the effects that material preferences and choices have on sibling social bids and cooperative play during a sibling training program. There were two main objectives. The first objective was to evaluate the effects of teaching with the high preference toy of the neuro-typical sibling during sibling training. The second objective was to determine if the training would produce different effects across four different toy conditions. Measures included social bids made by each of the siblings and cooperative play. Results indicate that teaching with the neuro-typical siblings' high preference toy during sibling training can be an effective method to increase social bids and cooperative play. The results of this study are discussed in the contexts of preference and choice selections, physical environments, motor skills, carry over effects, and participations based on gender.

Progressing from identification and functional analysis of precursor behavior to treatment of self-injury.

Progressing from identification and functional analysis of precursor behavior to treatment of self-injury.

Date: December 2009
Creator: Dracobly, Joseph Daniel
Description: An evaluation of the utility of assessing and treating severe problem behavior through precursor functional analysis was completed. Ongoing measurement of problem behavior in two settings in the participant's natural environment was conducted for the duration of the study. A precursor to self-injurious behavior was identified using descriptive assessment and conditional probability analyses. A precursor functional analysis was then conducted. Subsequently, a treatment, in which precursor behavior produced the maintaining variable identified in the precursor functional analysis, was implemented in the natural environment. Treatment resulted in increases in the precursor behavior and decreases in self-injury in both the treatment setting and the second setting in which observations occurred. Implications of the assessment and treatment procedures are discussed.

Progressing From Multiple-respondent Anecdotal Assessments to Test-control Analyses of Problem Behavior

Progressing From Multiple-respondent Anecdotal Assessments to Test-control Analyses of Problem Behavior

Date: May 2012
Creator: Staff, Martha Joe
Description: The current study was designed to evaluate the utility of progressing sequentially from multiple-respondent anecdotal assessments through test-control treatment analysis as an effective and efficient method of identifying the environmental determinants of problem behavior. the goal of the study was to evaluate overall agreement among multiple respondents on the primary function of aberrant behavior using the Motivation Assessment Scale (MAS) and Questions About Behavioral Function (QABF) and, if agreement was obtained, conduct a test-control evaluation to confirm anecdotal assessment findings while simultaneously evaluating the effects of function-based treatment. for 4 individuals, at least 4 of 5 respondents to the anecdotal assessments agreed (both within and across assessments) on the probable maintaining consequence for their problem behaviors. Test-control multielement evaluations were then conducted in which baseline sessions, corresponding to the suspected operant function of each individual’s problem behavior, were alternated with sessions in which the identified contingency was arranged for alternative behavior. Each evaluation showed substantial decreases in problem behavior and maintenance of alternative responses.
