Effects Of Trauma Induced Stress On Attention, Executive Functioning, Processing Speed, And Resilience In Urban Children, Antoinette Welsh Dec 2013

Effects Of Trauma Induced Stress On Attention, Executive Functioning, Processing Speed, And Resilience In Urban Children, Antoinette Welsh

Seton Hall University Dissertations and Theses (ETDs)

Brain development, and particularly structures involved in executive functioning, occurs at different rates in children, leading to differential performance in school. Due to neuroanatomical changes secondary to the stress response, children who have experienced stress as a result of poverty and traumatic events may be at increased risk for cognitive difficulties, including attention, executive functioning, and processing speed (Blair, Granger, & Razza, 2005; DeBellis, Hooper, & Sapia, 2005). Prevalence rates among urban children suggest that 70-100% have been exposed to trauma (Dempsey, Overstreet, & Moely, 2000; Macy, Baryry, & Noam, 2003). Some of these children develop posttraumatic stress disorder and …

An Investigation Into Peripersonal Space Representations In Older Adults, Emily K. Bloesch Aug 2013

An Investigation Into Peripersonal Space Representations In Older Adults, Emily K. Bloesch

Arts & Sciences Electronic Theses and Dissertations

Peripersonal space is the space immediately surrounding one's body. This space is believed to have a unique representation in order to facilitate successful interaction with the surrounding environment. Supporting this theory, there are consistent findings of changes in cognition within as compared to beyond peripersonal space, including differences in visual attention and perception. However, research on peripersonal space in healthy populations has largely focused on young adults. Representations of peripersonal space take place in multimodal brain regions, areas that show structural and functional changes during senescence. Because of this, there is reason to suspect that older adults represent peripersonal space …

The Impact Of Sexual Arousal On The Category Specificity Of Women's Visual Attention To Erotic Stimuli, Sarah Jones Aug 2013

The Impact Of Sexual Arousal On The Category Specificity Of Women's Visual Attention To Erotic Stimuli, Sarah Jones

UNLV Theses, Dissertations, Professional Papers, and Capstones

Research has shown that women have a much less category-specific pattern of visual attention to erotic stimuli than do men. That is, when simultaneously presented with male and female erotic stimuli, heterosexual women attend much more evenly to both male and female erotic stimuli than do heterosexual men, who attend almost exclusively to female stimuli. The present study investigated one proposed explanation for women's more diffuse visual attention patterns - that erotic female images have arousal value for heterosexual women. To test this hypothesis, heterosexual women were presented with either a 12-minute neutral, non-arousing video (n = 19) or a …

Visual Attention Bias And Body Dissatisfaction In Eating Disorders, Janet Lydecker Jul 2013

Visual Attention Bias And Body Dissatisfaction In Eating Disorders, Janet Lydecker

Theses and Dissertations

Eating disorders, such as anorexia and bulimia nervosa, have profound negative effects on the quality of life of both affected individuals and their families. Behavioral approaches such as cognitive-behavioral therapy (CBT) are commonly used for the treatment of these disorders. CBT teaches skills to restructure maladaptive thought patterns as a method of altering feelings and behaviors. However, even after CBT, 50-70% of women with bulimia and 67-87% of women with anorexia report continued eating disordered thoughts, feelings and behaviors. Measuring underlying cognitive processes such as orienting, maintaining, and executive attention in individuals with eating disorder symptomatology might be an important …

Attention's Grasp: Early And Late Hand Proximity Effects On Visual Evoked Potentials, Catherine L. Reed, David S. Leland, Benjamin Brekke '11, Alan Hartley Jul 2013

Attention's Grasp: Early And Late Hand Proximity Effects On Visual Evoked Potentials, Catherine L. Reed, David S. Leland, Benjamin Brekke '11, Alan Hartley

CMC Faculty Publications and Research

Behavioral studies suggest that visual attention is biased toward stimuli in the region of space near the palm of the hand, but it is unclear whether this effect is universal or selective for goal/task-related stimuli. We examined event-related potentials (ERPs) using a visual detection task in which the hand was placed near or kept far from target and non-target stimuli that were matched for frequency and visual features to avoid confounding factors. Focusing on attention-sensitive ERP components, we found that P3 (350–450 ms) amplitudes were increased for Hand Near conditions for targets only, demonstrating a selective effect consistent with the …

Relations Between Fine Motor Skill And Parental Report Of Attention In Young Children With Neurofibromatosis Type 1, Christy Casnar May 2013

Relations Between Fine Motor Skill And Parental Report Of Attention In Young Children With Neurofibromatosis Type 1, Christy Casnar

Theses and Dissertations

Neurofibromatosis type 1 (NF1) is one of the most common genetic disorders presenting in approximately 1 in 3,000 live births. NF1 is a highly variable condition with a large number of complications. A common complication is neuropsychological problems, including developmental delays and learning difficulties that affect as many as 60% of patients. Research has suggested the children with NF1 often have poorer fine motor skills and are at greater risk for attention difficulties than the general population. Furthermore, recent research is beginning to demonstrate a relationship between fine motor skills and attention in older children; however, very little research has …

Attention And Criminal Charge, Profile And Description: The Effect On Prospective Person Memory, Lindsey Nicole Sweeney May 2013

Attention And Criminal Charge, Profile And Description: The Effect On Prospective Person Memory, Lindsey Nicole Sweeney

Graduate Theses and Dissertations

Prospective person memory is the ability to recognize and react to a missing or wanted individual that one has been asked to be on the lookout for in the future. Prospective person memory relies on several processes including face recognition, event-based prospective memory, and attention. Only recently has research on the role of visual attention on prospective person memory been examined. In this dissertation, the gap between prospective person memory and attention is addressed. Although research on prospective person memory is steadily increasing, the research in this area is still in its infancy and the exact memory mechanisms that affect …

Does Visual Awareness Of Object Categories Require Attention?, Timothy S. Miller Jan 2013

Does Visual Awareness Of Object Categories Require Attention?, Timothy S. Miller

Masters Theses 1911 - February 2014

A key question in the investigation of awareness is whether it can occur without attention, or vice versa. Most evidence to date suggests that attention is necessary for awareness of visual stimuli, but that attention can sometimes be present without corresponding aware-ness. However, there has been some evidence that natural scenes in general, and in particular scenes including animals, may not require visual attention for a participant to become aware of their gist. One relatively recent paradigm for providing evidence for animal awareness without attention (Li, VanRullen, Koch, & Perona, 2002) requires participants to perform an attention demanding primary task …

Hyperactivity In Attention-Deficit/Hyperactivity Disorder (Adhd): Testing Functional Relationships With Phonological Working Memory Performance And Attention, Dustin Sarver Jan 2013

Hyperactivity In Attention-Deficit/Hyperactivity Disorder (Adhd): Testing Functional Relationships With Phonological Working Memory Performance And Attention, Dustin Sarver

Electronic Theses and Dissertations

Excessive gross motor activity is currently considered a ubiquitous and disruptive feature of attention-deficit/hyperactivity disorder (ADHD); however, an alternative model challenges this premise and hypothesizes a functional relationship between activity level, attention, and working memory. The current study investigated whether, and the extent to which, particular forms of gross motor activity are functionally related to children’s attention and phonological working memory performance. Objective observations of children’s gross motor movements and attention by independent observers were conducted while children with ADHD (n = 29) and typically developing children (n = 23) completed multiple counterbalanced tasks entailing low and high phonological working …

Do Programs Designed To Train Working Memory, Other Executive Functions, And Attention Benefit Children With Adhd? A Meta-Analytic Review Of Cognitive, Academic, And Behavioral Outcomes, Sarah Orban Jan 2013

Do Programs Designed To Train Working Memory, Other Executive Functions, And Attention Benefit Children With Adhd? A Meta-Analytic Review Of Cognitive, Academic, And Behavioral Outcomes, Sarah Orban

Electronic Theses and Dissertations

Children with ADHD are characterized frequently as possessing underdeveloped executive functions and sustained attentional abilities, and recent commercial claims suggest that computer-based cognitive training can remediate these impairments and provide significant and lasting improvement in their attention, impulse control, social functioning, academic performance, and complex reasoning skills. The present review critically evaluates these claims through meta-analysis of 25 studies of facilitative intervention training (i.e., cognitive training) for children with ADHD. Random effects models corrected for publication bias and sampling error revealed that studies training short-term memory alone resulted in moderate magnitude improvements in short-term memory (d= 0.63), whereas training attention …

Skill Acquisition And The Influence Of Attentional Focus And Practice, Alison Beth Regal Jan 2013

Skill Acquisition And The Influence Of Attentional Focus And Practice, Alison Beth Regal

Dissertations, Master's Theses and Master's Reports - Open

Attentional focus and practice schedules are important components in learning a new skill. For attention this includes focusing inward or outward, for practice this includes interference between tasks. Little is known about how the two interact. Four groups; blocked/extraneous (BE); blocked/skill-focused (BS); random/extraneous (RE); and random/skill-focused (RS), practiced 100 trials of golf putting and 64 trials of a key-pressing task in addition to responding to a random tone distracting attention towards or away from skill movement. Participants performed immediate and delayed retention tests. Results demonstrated the BE group had decreased RTE scores compared to the BS group. Immediate retention demonstrated …

The Effects Of Talker Variability And Talkers' Gender On The Perception Of Spoken Taboo Words, Samantha E. Tuft Jan 2013

The Effects Of Talker Variability And Talkers' Gender On The Perception Of Spoken Taboo Words, Samantha E. Tuft

ETD Archive

In the current experiment, I examined the effects of inter-talker variability and talkers' gender on listeners' perception of spoken taboo words. Previous spoken word recognition research using the long-term repetition-priming paradigm, in which listeners respond to two separate blocks of spoken words, found performance costs for stimuli mismatching in talker identity. That is, when words were repeated across the two blocks and the identity of the talker remained the same (e.g., male to male) reaction times (RTs) were faster relative to when the repeated words were spoken by two different talkers (e.g., male to female). Such performance costs, or talker …

Attention To Explicit And Implicit Contrast In Verb Learning, Jane B. Childers, Amy Hirshkowitz, Kristin Benavides Jan 2013

Attention To Explicit And Implicit Contrast In Verb Learning, Jane B. Childers, Amy Hirshkowitz, Kristin Benavides

Psychology Faculty Research

Contrast information could be useful for verb learning, but few studies have examined children's ability to use this type of information. Contrast may be useful when children are told explicitly that different verbs apply, or when they hear two different verbs in a single context. Three studies examine children's attention to different types of contrast as they learn new verbs. Study 1 shows that 3 ½-year-olds can use both implicit contrast (“I'm meeking it. I'm koobing it.”) and explicit contrast (“I'm meeking it. I'm not meeking it.”) when learning a new verb, while a control group's responses did not differ …

Interpretation Of The Wisc-Iv Working Memory Index As A Measure Of Attention, Talya J. Colliflower Jan 2013

Interpretation Of The Wisc-Iv Working Memory Index As A Measure Of Attention, Talya J. Colliflower

Theses, Dissertations and Capstones

The WISC-IV Working Memory Index is often interpreted as a valid measure of attention and concentration. Students who score low on the WMI are frequently viewed as having attention difficulties. If the WMI is accurately interpreted as a measure of attention, then students who score low on this composite should present with attention deficits in the classroom. Data of students who were referred for an evaluation to determine special education eligibility were compared to determine the accuracy of the interpretation of the WMI and its relationship with the Inattention and other scales on the Conners 3rd Edition – Teacher Form. …

Attentional Processes Associated With Victimization History And Posttraumatic Symptomatology In Women Exposed To Intimate Partner Violence, Ryan B. Matlow Jan 2013

Attentional Processes Associated With Victimization History And Posttraumatic Symptomatology In Women Exposed To Intimate Partner Violence, Ryan B. Matlow

Electronic Theses and Dissertations

Exposure to intimate partner violence (IPV) puts women at risk for severe and chronic physical and mental health consequences, including elevations in IPV-related psychopathology and increased risk for future victimization. Previous research has examined attention as one of the key information processing mechanisms associated with elevated psychopathology and risk for victimization; however, the nature of attentional processing in response to IPV-related information in women exposed to IPV is poorly understood. Therefore, the current study aimed to further understanding of associations between attentional processing, IPV exposure, and related distress using measures of eye movement and subjective interpretations of IPV-related information. A …

Memory For Elements Of A Complex Scene : Binding And The Influence Of Attention, Stephanie L. Martin Jan 2013

Memory For Elements Of A Complex Scene : Binding And The Influence Of Attention, Stephanie L. Martin

LSU Doctoral Dissertations

Memory of a complex event includes a multitude of features (e.g., objects, people, and actions) as well as the overall context (e.g., going to a picnic). To recall a complex event you must bind together these features and context into an episodic memory representation. This process of binding creates the subjective experience that certain details belong together. In two experiments, I examined whether particular types of information are bound together (object-to-object, object-to-context) within a memory representation of a scene and how attention may influence this process. Participants viewed a series of scenes and their attention was drawn to some objects …

What You Attend To Is What You Remember : Investigating The Unit Of Representation In Visual Working Memory, Amanda Elaine Van Lamsweerde Jan 2013

What You Attend To Is What You Remember : Investigating The Unit Of Representation In Visual Working Memory, Amanda Elaine Van Lamsweerde

LSU Doctoral Dissertations

The unit of representation in visual working memory (VWM) is a matter of some debate. The object benefit occurs when more features are remembered when they are combined into fewer objects. This has been used to support the perspective that objects are the unit of representation in VWM. However, the object benefit occurs only for two features from different dimensions (e.g., a blue circle: color and shape) but not two features from the same dimension (e.g., a red-and-blue bi-colored square: two colors). This suggests that both objects and features may be important in determining VWM capacity. The purpose of this …

Exploring The Impact Of Meditation On Attentional Allocation To Emotion, Sychopathology, And Acute Stress, In A Community Sample With Mixed Anxiety And Depression, Nicholas Thomas Van Dam Jan 2013

Exploring The Impact Of Meditation On Attentional Allocation To Emotion, Sychopathology, And Acute Stress, In A Community Sample With Mixed Anxiety And Depression, Nicholas Thomas Van Dam

Legacy Theses & Dissertations (2009 - 2024)

Attempts to define mindfulness in the clinical and psychological sciences have been marred by contradictions, inconsistencies, and controversies. In this wait-list (WL) controlled mindfulness meditation training (MMT) study, the efficacy and potential mechanisms of MMT was tested in a community sample with undiagnosed, but significant, symptoms of anxiety, depression, and stress. In a pre/post design, which also included 3 month follow-up, participants completed self-report measures, participated in a psychosocial stress task (before and after which they completed self-report mood questionnaires and had physiological and salivary neuroendocrine markers collected), and completed an emotional attentional blink paradigm. Compared to WL (n = …

Modeling Hiv-1-Associated Neurocognitive Disorders And The Therapeutic Effects Of The Phytoestrogen Metabolite S-Equol In The Hiv-1 Transgenic Rat, Landhing Mary Moran Jan 2013

Modeling Hiv-1-Associated Neurocognitive Disorders And The Therapeutic Effects Of The Phytoestrogen Metabolite S-Equol In The Hiv-1 Transgenic Rat, Landhing Mary Moran

Theses and Dissertations

HIV-1 associated neurocognitive disorders (HAND) continue to afflict individuals with HIV-1 in the combination antiretroviral treatment (cART) era, most notably affecting executive function, as well as preattentive processing. Currently, there is no effective treatment for HAND, with only adjunctive treatment targeting symptomatic relief. There were two hypotheses in this dissertation: 1) that HIV-1 Tg rats will show disruptions in measures of executive function and preattentive processing, as well as neural network alterations in the prefrontal cortex (PFC), a brain region implicated in executive function, and 2) that administration of the phytoestrogen metabolite S-equol will improve performance as measured by executive …

The Effect Of Background Music On Emotional Processing : Evaluation Using A Dot Probe Paradigm, Haans Drieberg Jan 2013

The Effect Of Background Music On Emotional Processing : Evaluation Using A Dot Probe Paradigm, Haans Drieberg

Theses : Honours

Music plays an important role in all of the world's cultures, and background music is an ever-present phenomenon. Despite this, few studies have formally addressed whether background music influences the way people think. The aim of this study was to discover whether the presence of background music can influence cognition. Specifically, the differential effects of music rated as being positive (inducing happy emotions) and negative (inducing anxiety) on a person's allocation of attention was investigated. A dot probe task with positive and negative word pairings, matched for length and frequency was used in order to test the hypotheses that the …
