The Interaction Of Feedback And Reward Contingency On Cardiovascular Reactivity During A Stressful Cognitive Task, Alvin B. Jin Nov 2014

The Interaction Of Feedback And Reward Contingency On Cardiovascular Reactivity During A Stressful Cognitive Task, Alvin B. Jin

Graduate Theses and Dissertations

Excessive sympathetic cardiovascular reactivity to stressful tasks is a risk factor for the development of cardiovascular disease (CVD). Many populations with a greater risk for CVD instead demonstrate blunted cardiovascular reactivity to stressful tasks. The motivational intensity theory identifies how motivation and effort influence sympathetic reactivity. Blunted reactivity may be a potential index of motivational dysregulation, which leads to poor behavioral decisions such as excess smoking or alcohol use, in turn increasing the risk for CVD. The current study sought to demonstrate how inhibited effort due to poor ability feedback with a low-contingency reward could directly increase the risk for ...


The Effects Of Collaborative Critical Thinking Training On Trust Development And Effectiveness In Virtual Teams, Mark Grichanik Nov 2014

The Effects Of Collaborative Critical Thinking Training On Trust Development And Effectiveness In Virtual Teams, Mark Grichanik

Graduate Theses and Dissertations

Workers in modern teams that perform tasks over computer-mediated communication channels encounter challenges in building trust and performing effectively. Finding interventions to mitigate such losses could improve team performance. Collaborative critical thinking (CCT) training has the potential to improve trust, monitoring, and effectiveness in virtual teams. Using a simulated search-and-rescue task, the effects of CCT training, as compared with a control training, were evaluated in 105 three-member teams. No effects of CCT training were found on team positive or negative monitoring, team cognitive or affective trust, team efficacy, or team viability. However, teams trained in CCT reported consistently higher levels ...


Developing An Animal Model Of Polysubstance Abuse In Adolescence: The Role Of Nmda Receptors In Alcohol/Cocaine Reward, Adriana Rebecca Uruena-Agnes Nov 2014

Developing An Animal Model Of Polysubstance Abuse In Adolescence: The Role Of Nmda Receptors In Alcohol/Cocaine Reward, Adriana Rebecca Uruena-Agnes

Graduate Theses and Dissertations

Repeated exposure to drugs of abuse conditions individuals to anticipate the behavioral consequences of drug use specifically in the presence of a drug-associated context. In rodents, preferences and aversions for alcohol and cocaine have been conditioned; however, the mechanisms underlying the expression of these conditioned effects remain unknown. Given that alcohol and cocaine polysubstance abuse is prevalent in young individuals, with more than 50% of these polysubstance abusers reporting to be under the age of 21, it is important to understand the mechanisms contributing to the behavioral effects of alcohol and cocaine co-dependency. Aim 1 determined if age differentially impacted ...


Using An Acceptance And Commitment Training Protocol To Decrease Drug Use, Alexander Brown Mclean Nov 2014

Using An Acceptance And Commitment Training Protocol To Decrease Drug Use, Alexander Brown Mclean

Graduate Theses and Dissertations

Behavior analysts have had much success in affecting behavior change with individuals diagnosed with intellectual disabilities as well as those who would be considered typically developing with a variety of intervention strategies; most of which involve affecting direct acting contingencies. However, the realm of language-based psychopathology has just begun to be addressed within the field through language based, or indirect acting strategies. Acceptance and Commitment Therapy (ACT) is based on the concept of derived stimulus relations and allows for a behavior analytic treatment of language-based psychopathology. The current study was intended to test the efficacy of a brief protocol-delivered ACT ...


Relating Relations: The Impact Of Equivalence-Equivalence Training On Analogical Reasoning, Anna Rosio Garcia Nov 2014

Relating Relations: The Impact Of Equivalence-Equivalence Training On Analogical Reasoning, Anna Rosio Garcia

Graduate Theses and Dissertations

A well-researched line showing equivalence performances in a wide variety of areas has been conducted in the field of Behavior Analysis (BA). One area demonstrates that relating relations is a behavioral account of analogical thinking. Relating relations may have implications for the development of analogical training given that analogical reasoning is seen as the foundation of intelligence yet research in this area is limited. A protocol by Stewart, Barnes-Holmes, and Weil (2009) was developed to train children in analogical reasoning using equivalence-equivalence relations. The purpose of this study was to evaluate an equivalence-equivalence training protocol based on Stewart et al ...


Blue Is In The Eye Of The Beholder: A Cross Cultural Study On Color Perception And Memory, Mark Douglas Lowry Oct 2014

Blue Is In The Eye Of The Beholder: A Cross Cultural Study On Color Perception And Memory, Mark Douglas Lowry

Graduate Theses and Dissertations

According the linguistic relativity hypothesis, the language one speaks affects how one thinks. Because languages differ in how they categorize color, linguistic relativity has often been tested by conducting experiments on color perception and memory. This study examines the linguistic relativity hypothesis using ecologically valid stimuli: pictures of eyes. Because Russian-speakers are more likely to describe blue/grey eyes as grey, whereas English speakers are more likely to describe them as blue, English and Russian participants were asked to match the overall color of blue eyes to a color scale. There were three conditions. In the first condition (perception), participants ...


Not Enough Cooks In The Kitchen: An Empirical Test Of A Two-Factor Model Of Work Unit Understaffing, Cristina Keiko Hudson Oct 2014

Not Enough Cooks In The Kitchen: An Empirical Test Of A Two-Factor Model Of Work Unit Understaffing, Cristina Keiko Hudson

Graduate Theses and Dissertations

Although most working adults possess a lay understanding of understaffing in the workplace and may, in fact, feel they are experiencing such a stressor, a review of the research literature reveals a general lack of empirical work on understaffing and its consequences. Hudson and Shen (2013, Development and testing of a new measure of understaffing. Paper presented at the Southern Management Association 2013 Meeting, New Orleans, LA) recently proposed a new model of understaffing that distinguished between two types of personnel deficiencies, manpower and expertise shortages, and linked these dimensions to worker well-being and attitudinal outcomes and identified likely mediating ...


Assessing The Effects Of Derived Relational Responding On Intraverbal Use Of Same-Opposite And More Than-Less Than Relations In Children With Autism, Jane P. White Oct 2014

Assessing The Effects Of Derived Relational Responding On Intraverbal Use Of Same-Opposite And More Than-Less Than Relations In Children With Autism, Jane P. White

Graduate Theses and Dissertations

Relational Frame Theory provides an analysis of verbal behavior involving a focus on the development of relational operants which are seen as a basis for language. From this basis, a framework is provided for establishing relational networks in individuals who lack derived relational ability. Establishment of relational frames may increase the probability of responding relationally to novel instances and use of the specific relational frames during social interactions; therefore, training verbal relations in accordance with an RFT approach may enhance intraverbal responding and facilitate the emergence of untrained responses. The purpose of this study was to evaluate the emergence of ...


Is More Always Better: Comparing The Effects Of Single And Multiple Learning Channels On Academic Performance, Samantha Ann Spillman Oct 2014

Is More Always Better: Comparing The Effects Of Single And Multiple Learning Channels On Academic Performance, Samantha Ann Spillman

Graduate Theses and Dissertations

Precision teaching (PT) is a measurement system used in multiple settings for all types of behavior, from driving to mathematics. The ultimate goal of PT is to develop fluent, free operant behaviors through analyzing response frequencies on a standard celeration chart. Research has found PT to be effective at improving both the speed and accuracy of academic skills. There is little research, however, in the effects of learning channels, a component of PT, as they relate to the acquisition of academic skills. The present study examined the relationship between single and multiple learning channels on the acquisition of mathematics skills ...


Family Accommodation In Adults With Obsessive-Compulsive Disorder: Psychometric Properties Of The Family Accommodation Scale - Patient Version, Monica S. Wu Oct 2014

Family Accommodation In Adults With Obsessive-Compulsive Disorder: Psychometric Properties Of The Family Accommodation Scale - Patient Version, Monica S. Wu

Graduate Theses and Dissertations

Family accommodation is a salient construct within the context of obsessive-compulsive disorder (OCD) and occurs in a large majority of affected individuals and their families. Accommodating behaviors can manifest in various ways, including participation in the patient's rituals, modifying everyday routines, facilitating compulsive behaviors, or providing reassurance. It has been repeatedly linked to negative outcomes, such as attenuated treatment response, increased obsessive-compulsive symptom severity, higher levels of family distress, and lower levels of functioning. As such, it is of significant clinical importance to have a standardized measure that is able to be used in research and clinical practice.

The ...


Self-Control And Alcohol Expectancies, John M. Ray Oct 2014

Self-Control And Alcohol Expectancies, John M. Ray

Graduate Theses and Dissertations

Research on self-control suggests that people do not do as well at self-control after they have already exerted self-control on something else. Despite the obvious importance of self-control in drinking behavior, few studies have examined alcohol consumption as an outcome measure in the context of self-control depletion and the potential role of cognitive processes in the self-control to drinking relationship remains largely unexplored. Although it is widely agreed that alcohol expectancies play an important role in one's decision to drink, no study has examined the role of expectancies in self-control's influence on drinking. This study addresses this important ...


Improving Middle School Students' Subjective Well-Being: Efficacy Of A Multi-Component Positive Psychology Intervention Targeting Small Groups Of Youth And Parents, Rachel Anne Roth Oct 2014

Improving Middle School Students' Subjective Well-Being: Efficacy Of A Multi-Component Positive Psychology Intervention Targeting Small Groups Of Youth And Parents, Rachel Anne Roth

Graduate Theses and Dissertations

A dual-factor model of mental health conceptualizes mental health status as a combination of both psychopathology and subjective well-being. Current literature indicates that complete mental health (i.e., low psychopathology, high subjective well-being) is associated with the best academic and social functioning among youth. Thus, the absence of psychopathology alone is not sufficient for student success. While research on interventions for improving subjective well-being, termed positive psychology interventions (PPIs), is increasing, PPIs for youth in particular lag behind similar interventions for adults. Additionally, a majority of youth-focused PPIs have targeted singular constructs (e.g., gratitude, character strengths), have neglected to ...


Using Mimic Methods To Detect And Identify Sources Of Dif Among Multiple Groups, Seokjoon Chun Sep 2014

Using Mimic Methods To Detect And Identify Sources Of Dif Among Multiple Groups, Seokjoon Chun

Graduate Theses and Dissertations

This study investigated the efficacy of multiple indicators, multiple causes (MIMIC) methods in detecting uniform and nonuniform differential item functioning (DIF) among multiple groups, where the underlying causes of DIF was different. Three different implementations of MIMIC DIF detection were studied: sequential free baseline, free baseline, and constrained baseline. In addition, the robustness of the MIMIC methods against the violation of its assumption, equal factor variance across comparison groups, was investigated. We found that the sequential-free baseline methods provided similar Type I error and power rates to the free baseline method with a designated anchor, and much better Type I ...


A Contingency Model Of Team Leadership For Emergency Medical Teams, Andeneshea Shacardia Kemp Sep 2014

A Contingency Model Of Team Leadership For Emergency Medical Teams, Andeneshea Shacardia Kemp

Graduate Theses and Dissertations

Emergency medical teams operate under unusual circumstances. They assemble for a singular, temporary purpose, potentially change in size and composition, and their performance can influence whether a patient lives or dies. Although leadership is a critical component to team success, it is rarely investigated in the context of emergency medical teams. This study sought to examine the relationship between directive leadership behaviors and team performance outcomes. It was hypothesized that directive leadership would be particularly effective for emergency medical teams. In addition, a contingency model was proposed. Specifically, it was hypothesized that the effectiveness of directive leadership is contingent upon ...


Developmental Trajectories Of Physical Aggression And Nonaggressive Rule-Breaking Among At-Risk Males And Females During Late Childhood And Early Adolescence, Eugena Givens Sep 2014

Developmental Trajectories Of Physical Aggression And Nonaggressive Rule-Breaking Among At-Risk Males And Females During Late Childhood And Early Adolescence, Eugena Givens

Graduate Theses and Dissertations

Criminological, psychological, and developmental researchers have relentlessly explored behavioral characteristics and juvenile justice outcomes in an effort to establish the most appropriate means of analyzing childhood and adolescent problem behaviors. Cross-discipline, empirical evidence and factor analytic research has consistently identified the presence of two predictive concepts, physical aggression and nonaggressive rule-breaking. Research pertaining to the risk factors and correlates of these two distinct substructures of offending align with theoretically postulated typologies of delinquency and offending as well as the frequently cited patterns of delinquency and offending within reviews of longitudinal research. Using longitudinal data from a sample of 756 at-risk ...


Fear Of Cancer Recurrence In Breast Cancer Survivors Before And After Follow-Up Mammograms, Heather L. Mcginty Aug 2014

Fear Of Cancer Recurrence In Breast Cancer Survivors Before And After Follow-Up Mammograms, Heather L. Mcginty

Graduate Theses and Dissertations

The purpose of this study was to assess fear of cancer recurrence (FCR) in breast cancer survivors returning for regularly scheduled follow-up mammograms. FCR was hypothesized to increase prior to the mammogram, decrease from immediately pre- to immediately post-mammogram, and then increase following the mammogram. Based on the cognitive-behavioral model (CBM) of health anxiety, greater perceived risk of recurrence, worse perceived consequences of a recurrence, lower coping self-efficacy, and more engagement in reassurance-seeking behaviors were hypothesized to be associated with greater FCR in each time segment. Finally, exploratory analyses evaluated the various trajectories in FCR over time using growth mixture ...


The Importance Of Family-Systems Theory In Masters-Level School School Counseling Curriculum: A Study Of Faculty Perceptions, Gwen Gold Aug 2014

The Importance Of Family-Systems Theory In Masters-Level School School Counseling Curriculum: A Study Of Faculty Perceptions, Gwen Gold

Graduate Theses and Dissertations

This study examined the perceptions of Council for Accreditation of Counseling & Related Educational Programs (CACREP) master's-level school counseling program coordinators and faculty members about the importance and relevance of family systems theory and techniques coursework in their program curriculum. Family-systems theory coursework is lacking in two-thirds of those accredited programs, although mandated by their major accrediting body, CACREP. CACREP issued curriculum standards and guidelines to ensure proper training of school-counseling students and the American School Counselor Association--the foundation that expands the image and influence of professional school counselors through advocacy, leadership, collaboration, and systemic change--has issued guidelines for the ...


Adolescent Behavioral Adjustment In Girls Adopted From China: Examining Pre-Adoption And Post-Adoption Factors, Derek Justin Powers Jul 2014

Adolescent Behavioral Adjustment In Girls Adopted From China: Examining Pre-Adoption And Post-Adoption Factors, Derek Justin Powers

Graduate Theses and Dissertations

Despite research that indicates that internationally adopted children are at greater risk for poor developmental outcomes than their non-adopted peers (Bimmel, Juffer, IJzendoorn, Bakermans-Kranenburg, 2003; Juffer, & van IJzendoorn, 2005), girls adopted from China into Western culture tend to thrive, exhibiting high self-esteem, low behavior problems (i.e., both externalizing and internalizing), and excelling academically (Rojewski, Shapiro, & Shapiro, 2000; Tan & Jordan-Arthur, 2012). However, few studies have examined whether this trend continues into adolescence, as well as to what factors lead to these positive outcomes. The purpose of this study was to investigate predictors of mental health outcomes among internationally adopted adolescent Chinese girls, particularly factors that predicted levels of internalizing pathology (e.g., depression and anxiety) in adolescence. To fulfill this purpose, a secondary data analysis (N = 167) of information collected as part ...


Bayesian Models Of Sequential Dependencies In Binary And Multi-Interval Response Tasks, Jeffrey Scott Annis Jul 2014

Bayesian Models Of Sequential Dependencies In Binary And Multi-Interval Response Tasks, Jeffrey Scott Annis

Graduate Theses and Dissertations

A sequential dependency occurs when the response on the current trial is correlated with responses made on prior trials. Sequential dependencies have been observed in a variety of both perception and memory tasks. Thus, sequential dependencies provide a platform for relating these two cognitive processes. However, there are many issues associated with measuring sequential dependencies and therefore it is necessary to develop measurement models that directly address them. Here, several measurement models of sequential dependencies for both binary and multi-interval response tasks are described. The efficacy of the models is verified by applying them to simulated data sets with known ...


Effects Of Workplace Incivility On Nurses' Emotions, Well-Being, And Behaviors: A Longitudinal Study, Zhiqing Zhou Jul 2014

Effects Of Workplace Incivility On Nurses' Emotions, Well-Being, And Behaviors: A Longitudinal Study, Zhiqing Zhou

Graduate Theses and Dissertations

This dissertation used an experience sampling design to examine effects of experienced workplace incivility from three categories of organizational insiders (coworkers, supervisors, and physicians) and from organizational outsiders (patients and their visitors) on targets' emotions, burnout, physical symptoms, and their own uncivil behaviors toward each of the four groups of people. Data were collected from 75 nurses with each nurse responding to online surveys twice per week for 5 consecutive weeks. Results from hierarchical linear modeling showed that within individuals, negative emotions were positively associated with experienced workplace incivility (overall and source-specific), burnout was positively associated with overall workplace incivility ...


Just Love: A Collaborative Evaluation Of A Faith-Based School-Family-Community Partnership Through The Voices Of The Children, Lynette M. Henry Jun 2014

Just Love: A Collaborative Evaluation Of A Faith-Based School-Family-Community Partnership Through The Voices Of The Children, Lynette M. Henry

Graduate Theses and Dissertations

Abstract

Faith-based school-family-community partnerships have been a federal mandate over the past decade, yet little has been written about the outcomes of these faith-based partnerships. A need exists to understand if the potential in these faith-based partnerships is indeed realized in positive outcomes for students and schools. The purpose of this study was to evaluate a faith-based school-family-community partnership, Just Love. Just Love is a faith-based school-family-community partnership between a large suburban church and a Title 1, urban elementary school, Charisma Elementary School (Charisma ES; pseudonym). It was implemented in what is considered a "failing school". Just Love's purpose ...


Testing The Correlation Between Response Latency, Derivation, And Complexity, Jeffrey Ryan Oliver Jun 2014

Testing The Correlation Between Response Latency, Derivation, And Complexity, Jeffrey Ryan Oliver

Graduate Theses and Dissertations

This study investigates the constructs of Derivation and Complexity and how they relate to latency. Derivation and Complexity are theoretical constructs that have been posited as two of the main factors in differences in latency to responding in implicit measures such as the Implicit Relational Assessment Procedure (IRAP) and the Implicit Association Task (IAT). This study trained participants to relate two groups of novel stimuli in a linear fashion and then tested their latency to responding to derived relations (relations based on previously trained relations, but not directly trained themselves). The study then analyzed participant's latency to responding after ...


The Influence Of Individual Differences On Emotional Processing And Emotional Memory, Patricia Lynn Johnson Jun 2014

The Influence Of Individual Differences On Emotional Processing And Emotional Memory, Patricia Lynn Johnson

Graduate Theses and Dissertations

Emotional material is better remembered than neutral material and some suggest this is reflected in different Event Related potentials (ERPs) to affective stimuli by valence. Inconsistent results may be due to individual differences, specifically the behavioral inhibition/behavioral activation (BIS/BAS) motivational system. This study sought to examine the relationship between motivational systems, emotional memory, and psychophysiological response to emotional pictures. While using EEG recording, subjects were shown 150 affective pictures and given a recall and yes/no recognition task after a 20 and 30-minute delay, respectively. Overall, differences were found by valence, but not consistently based on individual trait ...


The Invention Of Lying (At Work): The Development And Validation Of A Situational Judgment, Jeffrey S. Conway Jun 2014

The Invention Of Lying (At Work): The Development And Validation Of A Situational Judgment, Jeffrey S. Conway

Graduate Theses and Dissertations

The focus of the current dissertation was on the construction and validation of a situational judgment test (SJT) assessing lying/dishonesty in the workplace. The scale was designed to have two dimensions corresponding to two needs based on Socioanalytic Theory: (1) the need to get along and (2) the need to get ahead. Three studies were undertaken in order to create items, pilot test items, and assess both the construct and criterion-related validity of the scale. The result of Study 1 was a pilot-tested scale with six SJT items corresponding to each of the two SJT dimension (12 items total ...


Relationships Between Life Satisfaction, Symptoms Of Inattention And Hyperactivity/Impulsivity, And Depressive Symptoms In High School Students, Lisa Paige Bateman Jun 2014

Relationships Between Life Satisfaction, Symptoms Of Inattention And Hyperactivity/Impulsivity, And Depressive Symptoms In High School Students, Lisa Paige Bateman

Graduate Theses and Dissertations

Given increased evidence related to the importance of fostering life satisfaction in the overall population (Diener & Diener, 1996), as well as recent suggestions regarding the importance of increasing positive academic and social outcomes for children with ADHD (DuPaul, 2007), it is important to gain a clearer understanding of how life satisfaction may be related to symptoms of inattention and hyperactivity/impulsivity. Research on the relationship between life satisfaction and symptoms of inattention, hyperactivity, and impulsivity is currently limited to two studies (Gudjonsson et al., 2009; Ogg et al., 2014). The current study investigated the relationship between symptoms of inattention and hyperactivity/impulsivity and reports of global life satisfaction in 399 high school students. This study used the bifactor model to conceptualize ADHD given that this model provided the best fit when compared to other models of ADHD in the current study and given that there is substantial evidence in the current literature to support the use of this model (Martel, von Eye, & Nigg, 2010). Structural equation modeling results demonstrated ...


Illness Perceptions Of Polycystic Ovary Syndrome, Elizabeth Baker Jun 2014

Illness Perceptions Of Polycystic Ovary Syndrome, Elizabeth Baker

Graduate Theses and Dissertations

Polycystic ovary syndrome (PCOS) is a chronic illness that affects approximately five million premenopausal women in the United States and is associated with significant cosmetic, reproductive, metabolic, and psychological consequences. Despite its prevalence, few studies have explored the lived experiences and illness perceptions of women living with PCOS. Identifying illness perceptions of women living with (WLW) PCOS is important, because mounting research suggests that a person's perceptions of their chronic illness and its management determine that person's coping behaviors (e.g., adherence, self-management) and, consequently, illness outcomes.

In this dissertation, the Common Sense Model (CSM) is used as ...


Perceived Discrepancies In Men's Motivations For Gender-Conforming Behaviors And Romantic Relationship Outcomes, Jonathan Robert Weaver May 2014

Perceived Discrepancies In Men's Motivations For Gender-Conforming Behaviors And Romantic Relationship Outcomes, Jonathan Robert Weaver

Graduate Theses and Dissertations

Healthy romantic relationships are positively associated with physical and mental health outcomes, and past research has shown that traditional masculinity negatively impacts relationship satisfaction. The current study examined the effects of men's discrepancies between their self-ratings and perceptions of their peers' on autonomous and pressured motivations to act agentically on relationship outcomes for both partners in a heterosexual relationship. In addition, men's investment in gender ideals was measured as a potential moderator and men's self-esteem as a potential mediator. Specifically, it was predicted that men's self-esteem would mediate the association between the investment-by-discrepancies (autonomous and pressured ...


Self-Control Depletion And Nicotine Deprivation As Precipitants Of Smoking Cessation Failure: A Human Laboratory Model, Bryan Heckman May 2014

Self-Control Depletion And Nicotine Deprivation As Precipitants Of Smoking Cessation Failure: A Human Laboratory Model, Bryan Heckman

Graduate Theses and Dissertations

The need to understand the reinforcing properties of smoking and potential precipitants of relapse is exemplified by evidence that relapse rates exceed 95%. The Self-Control Strength model, which proposes that self-control is dependent upon limited resources and susceptible to fatigue, may offer insight into the relapse process. Indeed, there is empirical support that engaging in a task that requires self-control, relative to a comparable control, results in performance decrements on subsequent self-control tasks. The primary goal of the current study was to test whether self-control depletion (SCD) may serve as a novel antecedent for cessation failure, using a validated laboratory ...


Savor The Memory: A Reminiscence Exercise To Increase Positive Emotions And Reduce Depression Risk In Anxious Individuals, Bethany Morris May 2014

Savor The Memory: A Reminiscence Exercise To Increase Positive Emotions And Reduce Depression Risk In Anxious Individuals, Bethany Morris

Graduate Theses and Dissertations

A growing literature suggests that experiencing positive emotions provides psychological benefits (e.g., Coifman et al. 2007), and interventions increasing positive emotions may reduce depression risk (Geschwind et al., 2011). The present study tested whether reminiscence, a method of positive emotion savoring (Quoidbach et al., 2010), can mitigate depression risk by increasing positive emotions in an unselected sample and a subsample of at-risk anxious individuals. Female participants (n=336) were randomized to a reminiscence or control condition and asked to complete daily mental imagery exercises focusing on a positive memory (reminiscence) or a neutral laboratory memory (control) for one week ...


An Examination Of Electrodermal Activity During Tic Suppression In Adults, Bryan Brandt May 2014

An Examination Of Electrodermal Activity During Tic Suppression In Adults, Bryan Brandt

Graduate Theses and Dissertations

Although tic disorders are diagnosed as neurological disorders, neurobehavioral models suggest that tics are controlled by premonitory urges that may be conditioned to become aversive through childhood, and that tics are exhibited to alleviate such phenomena. However, only indirect measures have been used to assess the presence of the premonitory urge. This study utilized self-report and GSR measurements to examine whether a punishing contingency conditioned stimuli to be aversive during conditions of tic suppression and whether punishing contingencies exacerbate aversive private phenomena in two adults. Results indicated that conditions of response cost (RC) and differential reinforcement (DRO) were effective at ...
