If Or When? Uncertainty's Role In Anxious Anticipation, Kenneth P. Bennett

Theses and Dissertations

Uncertainty is often associated with subjective distress and a potentiated anxiety response. Occurrence uncertainty (OU), or the inability to predict if a threat will occur, has never been compared experimentally with temporal uncertainty (TU), or the inability to predict when a threat will occur. The current study aimed to 1) directly compare the eye-blink startle responsivity of OU and TU, 2) develop a more effective task for isolating uncertain anticipation, and 3) better understand the relationship between individual differences in the intolerance of uncertainty and uncertain anticipation startle responsivity. The novel study showed that OU anticipation is more anxiety provoking …

An Exploration Of Student Anxiety And The Degree Of Aba Services, Alexis Stavros

Theses and Dissertations

Children diagnosed with Autism may present numerous internalizing and externalizing behaviors. In order to help decrease problematic behaviors and promote positive behaviors, early intervention programs are often put into place. Applied Behavior Analysis (ABA) is a method of intervention based in operant conditioning, and is used to alter socially useful behavior (Kearney, A. 2008). Although ABA can be effective in decreasing problematic behavior, it could be argued that children diagnosed with Autism exhibit a range of symptoms that may be more internalizing in nature, and not particularly responsive to ABA (Herbert, Brandsma, 2002: Fryling, 2011). Research states that 84% of …

Neural Circuitry Underlying The Intrusion Of Task-Irrelevant Threat Into Working Memory In Anxiety, Daniel Stout

Theses and Dissertations

Dispositional anxiety is an important risk factor for the development of anxiety and other psychological disorders. Symptoms commonly expressed by highly anxious individuals include intrusive memories, uncertainty, and worry — all occurring in the absence of immediate threat. This raises the possibility that anxious individuals have difficulty governing threat’s access to working memory, the mental workspace where goal-related information is actively retained for guiding on-going behavior. Using functional magnetic resonance imaging (fMRI) while 81 subjects completed a well-validated working memory task, I show that threat-related and neutral distracters unnecessarily gain access to working memory, as evidenced by increased neural activity …

Neural Plasticity Of Extinction: Relations With Anxiety And Extinction Retention, Emily Louise Belleau

Theses and Dissertations

ABSTRACT

NEURAL PLASTICITY OF EXTINCTION LEARNING: RELATIONS WITH ANXIETY AND EXTINCTION RETENTION

by

Emily L. Belleau

The University of Wisconsin-Milwaukee, 2016

Under the Supervision of Associate Professor Christine Larson

Anxiety is a significant public health problem characterized by substantial psychological, physical, and economic burden. A key feature of anxiety is the inability to regulate fear. Aberrant extinction of conditioned fear is one prominent model of the etiology of anxiety disorders. Previous studies have shown that the neural circuitry underlying anxiety pathology overlaps with that mediating fear extinction learning. Recently, more precise pathways supporting the expression (CMA-aMCC) and inhibition (BLA-vmPFC) of …

Developmental Changes In Response To Music-Evoked Emotion Among Children And Adolescents With Autism Spectrum Disorders, Kevin G. Stephenson

Theses and Dissertations

Significant symptoms of anxiety in individuals with autism spectrum disorder (ASD) may arise due to impaired emotion recognition. In light of reports showing ASD-specific developmental changes in amygdala volumes, we expanded a previous study of recognition of music-evoked emotions in ASD versus typical controls (CON). We explicitly compared both behavioral and psychophysiological response to music-evoked emotions of children (ages 8-11) and older adolescents (ages 16-18). A total of 91 participants (42 ASD) listened to segments of instrumental music that had been previously validated to evoke happy, sad, or scary emotional valence. We measured accuracy and reaction time while also …

The Influence Of Adhd Symptoms And Social Impairment On Anxiety And Depression Symptoms In 8- To 10-Year-Old Children, Danielle Brooke Willis

Theses and Dissertations

Previous research has shown that Attention-Deficit/Hyperactivity Disorder (ADHD) is associated with impaired social functioning in children and adolescents. ADHD and increased social impairment have proven to be separately correlated with increased anxiety and depression symptoms as well. However, little research has examined these specific associations and interactions among ADHD, social functioning, and internalizing symptoms. The current study aimed to examine the influence of ADHD symptoms and social functioning on anxiety and depression symptoms in 321 8- to 10- year-old children, and specifically, if social impairment moderated the relation between ADHD symptoms and anxiety and depression symptoms. Data on ADHD, social …

Longitudinal Examination Of Observed Family Hostility And Adolescent Anxiety And Depression As Mediated By Adolescent Perspective Taking And Empathic Concern, Trevor Dennis Dahle

Theses and Dissertations

The purpose of this longitudinal study was to examine hostility in family interaction and its impact on adolescent depression and anxiety with adolescent perspective taking and empathic concern as mediators. Gender differences were also examined. Adolescents were from 353 two-parent families in a large north-western city in the United States and on average were 13.25 years old (SD=1.01) for girls and 13.30 years (SD=.99) for boys at the beginning of the study. This study utilized data from waves 3-5. Earlier waves of data were not used because some of the measures were not available for earlier waves. Results indicated that …

Facial Expressions In Generalized Anxiety Disorder, Lauren Noble

Theses and Dissertations

This study found that greater displays of sad facial expressions and body movement are associated with higher self-reported anxiety-related symptoms in those with GAD. In the control group, lower scores on rumination and worry scales are associated with greater displays of fearful facial expressions during the fear video.

A Brief Rational Disputation Exercise Enhances Cardiovascular, Anxiety, And Affective Recovery Following Worry-Recall, Michelle Rosalie Di Paolo

Theses and Dissertations

Rational Emotive Behavior Therapy (REBT) (Ellis, 1958), educates a client on the relationship between one’s irrational beliefs (IBs) and the dysfunctional emotional/behavioral consequences of maintaining those beliefs such as symptoms of anxiety, depression, and sleep dysfunction (Ellis, Gordan, Neenan, & Palmer, 1997), symptoms also commonly correlated with high trait perseverative cognition (PC; Verkuil, Brosschot, de Beurs, & Thayer, 2009). In addition to symptoms of anxiety and depression, high levels of PC, a construct comprised of measures of trait worry and rumination, have been linked to acute cardiovascular (CV) health concerns that overtime when left unmitigated may lead to chronic conditions …

The Relationship Between Dispositional Mindfulness Characteristics And Anxiety In High Functioning Adults Diagnosed With Autism Spectrum Disorder, Max Emanuel Maisel

Theses and Dissertations

Adults with autism spectrum disorder (ASD) experience elevated levels of anxiety and worry compared to neurotypical people. However, there is a dearth of extant research on effective interventions for comorbid anxiety and worry in this population. Mindfulness, which is often defined as paying attention to the present moment in a nonjudgmental manner, has been shown to be a propitious treatment for anxiety, worry, and other psychological ailments in neurotypical people. However, in a relatively new area of study, evidence has been growing which suggests mindfulness can also be effective in helping people with ASD cope with anxiety and worry. The …

The Influence Of Test Anxiety On Memory, James J. Malloy

Theses and Dissertations

The purpose of this study was to investigate the relationship between test anxiety and memory among a college population (N = 42). Specifically, the goal was to ascertain whether text anxiety had a measurable effect on memory, which was represented by scores on the Nelson-Denny reading comprehension subtest. Participants were divided into a stressed group (N = 22) and a non-stressed group (N = 20) in order to compare scores from test-takers with anxiety to those who do not. It was hypothesized that (a) test anxiety would have a significant impact on test results, (b) the non-stressed group would score …
