The Neural Correlates Of Emotion Reactivity And Regulation In Young Children With Adhd, Claudia I. Lugo-Candelas
The Neural Correlates Of Emotion Reactivity And Regulation In Young Children With Adhd, Claudia I. Lugo-Candelas
Doctoral Dissertations
Attention-deficit hyperactivity disorder (ADHD) is the most frequently occurring pediatric neurobehavioral disorder. Although emotion reactivity and regulation are frequently impaired in ADHD, few studies have examined these factors in preschool aged children with ADHD, and none have explored the neural correlates of emotion reactivity and regulation in this group though event-related potentials (ERPs). Children aged 4 to 7 with (n = 24) and without (n = 30) ADHD symptoms completed an attention task composed of four blocks: baseline, frustration, suppression, and recovery. In the frustration and suppression blocks, negative affect was induced by false negative feedback. During the …
Differences In Depression, Anxiety, And Life Satisfaction Between Intercollegiate Athletes, Intramural Participants, And Non-Athletes, Megan Wilson
Masters Theses & Specialist Projects
It is widely supported that participation in athletics is positively correlated with increased overall health. However, some research indicates that participation in increased levels of competition is positively correlated with higher levels of depression and anxiety. This means, that if compared, athletes competing nationally or internationally would report higher levels of both depression and anxiety than athletes competing at the intercollegiate level. Research indicates that this could be caused by increased amounts of pressure, personal cost, and expectation.
This study examines potential differences between intercollegiate, intramural, and non-athletes in these areas on a college campus. The first hypothesis is that …
Examining Relationships Between Basic Emotion Perception And Musical Training In The Prosodic, Facial, And Lexical Channels Of Communication And In Music, Jamie Twaite
Dissertations, Theses, and Capstone Projects
Research has suggested that intensive musical training may result in transfer effects from musical to non-musical domains. There is considerable research on perceptual and cognitive transfer effects associated with music, but, comparatively, fewer studies examined relationships between musical training and emotion processing. Preliminary findings, though equivocal, suggested that musical training is associated with enhanced perception of emotional prosody, consistent with a growing body of research demonstrating relationships between music and speech. In addition, few studies directly examined the relationship between musical training and the perception of emotions expressed in music, and no studies directly evaluated this relationship in the facial …
Neural Circuitry Underlying The Intrusion Of Task-Irrelevant Threat Into Working Memory In Anxiety, Daniel Stout
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 …
Eye Movement Effects In Simulated Object Recognition Memory Impairment, Dmitriy Kazakov
Eye Movement Effects In Simulated Object Recognition Memory Impairment, Dmitriy Kazakov
Theses and Dissertations
Malingering is the purposeful fabrication of symptoms for secondary gain. Memory problems are the most reported symptom, and object recognition tests are often used in clinical settings to evaluate these claims. Past research has shown that eye movements can indirectly index memory, in that greater viewing is directed at studied stimuli 500-750 ms after display onset. The present study evaluated eye movements as a potential method of detecting feigned memory impairment. Forty-eight participants, half simulators, studied standardized images and took a memory test. Several levels of analysis were used to detect broad trends and brief effects. Simulators performed significantly worse …
Cannabis Use And Affective Processing: A Brain Structure Analysis, Kristin E. Maple
Cannabis Use And Affective Processing: A Brain Structure Analysis, Kristin E. Maple
Theses and Dissertations
Cannabis is the most commonly used illicit drug amongst adolescents and young adults in the United States. Previously, cannabis and its components have been associated with differences in affective processing and neural functioning. Participants (ages 16-25) were cannabis users and non-users excluded for psychiatric disorders, major medical conditions, and excessive other drug use. A series of multiple regressions examined whether past year cannabis use and cannabis x gender predicted measures of emotional face processing (using the PennCNP affective battery) as well as volumes in bilateral prefrontal, temporal, limbic, and cerebellar regions, as well as frontolimbic white matter tracts. Subsequently, Pearson …

Effect Of Prior Trauma Exposure On Alpha Amplitude, Heart Rate, And Self-Reported Negative Affect, Gina L. Denoble
Effect Of Prior Trauma Exposure On Alpha Amplitude, Heart Rate, And Self-Reported Negative Affect, Gina L. Denoble
All Master's Theses
This study was conducted to investigate whether the number of traumatic events an individual has previously experienced influences that individual’s physiological and psychological reactions when exposed to a negative affective stimulus followed by a mindfulness-based stress reduction (MBSR) intervention. Twenty-eight participants were placed into intact quasi-experimental groups based on their scores on the Traumatic Life Events Questionnaire (TLEQ). The negative affective stimulus consisted of a series of photos bearing negative affective valence. The photos were selected from the International Affective Picture System (IAPS), and paralleled the areas of trauma exposure evaluated by the TLEQ. All participants were exposed to the …
Reduced Conscious Recollection And Its Detection In Three Performance Validity Tests : A Dual Task Interference Investigation, Graham Michael Silk-Eglit
Reduced Conscious Recollection And Its Detection In Three Performance Validity Tests : A Dual Task Interference Investigation, Graham Michael Silk-Eglit
Legacy Theses & Dissertations (2009 - 2024)
Performance validity is an essential component of neuropsychological assessment. Research suggests that examinees with specific neurological conditions cannot successfully complete certain performance validity tests (PVTs). However, very little basic research has explored the information processing underlying performance on PVTs that might explain why these examinees fail certain PVTs. The current study used a dual task interference paradigm to isolate the impact of reducing conscious recollection on the performance of three PVTs, the Test of Memory Malingering (TOMM), Victoria Symptom Validity Test (VSVT), and Word Memory Test (WMT). One-hundred-and-twenty-six non-clinical undergraduate research participants were administered these three PVTs as part of …

Rates of anxiety and depression are prevalent in college students and can be attributed in part to stress and trauma-related events. However, studies suggest that pet ownership has the possibility of alleviating symptoms of anxiety, depression, negative emotions, and suicide. The purpose of this study was to determine the relationship between pet ownership and levels of anxiety and depression among those who have experienced a traumatic event. The sample was comprised of five hundred and forty-seven VCU students who completed an online survey from Spit for Science during their junior year. Linear regressions were performed to determine the nature and …
The 2d:4d Ratio, Handedness, And Sex Across The Age Span, Helen A M Protopapas Ms.
The 2d:4d Ratio, Handedness, And Sex Across The Age Span, Helen A M Protopapas Ms.
Theses and Dissertations (Comprehensive)
The ratio of the difference between the 2nd and 4th digits of the hand (2D:4D ratio) has been demonstrated to be an indirect indicator of prenatal testosterone levels. Prenatal testosterone has been found to play a role in brain development in utero, and thus may influence lateral asymmetries, such as handedness. Consequently, one of the aims of the current study was to examine relationships between the 2D:4D ratio, hand preference, and hand performance with the factors of sex (males and females), handedness (right handers and left handers), and age considered. A total of 104 participants were tested, 90 right handers …
