If It Feels Good, View It: Selective Exposure And Desensitization Moderate The Association Between Video Gameplay And Pleasure-Oriented Aggression, Mejdy M. Jabr

University of New Orleans Theses and Dissertations

A number of studies have indicated that violent video gameplay is associated with higher levels of aggression, and desensitization to violent content contributes to this association. Utilizing a rapid serial visual presentation (RSVP) task, the current study used event-related potentials (ERPs) to investigate selective attention (N1 activation), cognitive control (N2 activation), and desensitization (P3 activation) as neurocognitive mechanisms potentially underlying the association between gameplay and subtypes of aggression. Results showed video game players and non-players differed significantly in brain activation when engaged with violent imagery. N1 and P3 amplitude moderated the association between gameplay and pleasure-oriented aggression. Follow-up analyses further …

The Relationship Between P300 Evoked Potentials And Prefrontal Cortex Oxygen Use: A Combined Eeg And Nirs Study, Will S. Rizer

All NMU Master's Theses

The P300 subcomponent, P3b, is an event related potential detected at the scalp surface when a working memory comparison results in differences between the contents of working memory and incoming stimulus information. Previous research has indicated that as infrequent targets become more difficult to detect (morphologically similar to a frequent non-target stimulus) the P300 becomes attenuated. fMRI research has also indicated increased prefrontal cortex (PFC) activity during P300 generation. To examine the relationship between P3b amplitude and PFC activity participants performed an easy and difficult target detection task in both EEG and NIRS called the oddball. The EEG and behavioral …

Erp Critical Success Factors: Importance Of Erp Consultants In Erp Implementation, Adekunle S. Balogun

Dissertations and Theses

Enterprise Resource Planning, ERP is one of the most popular and successful information technology solution used in many organizations to share information within different business units to enhance and maximize productivity. The system is expensive, time-consuming, and complicated to implement and manage. The difficulties of ERP implementation have resulted in high rates of unsuccessful ERP implementation according to the stories of many organizations that have implemented the solution. The failure of ERP implementation has then led to several studies to investigate the Critical Success Factors (CSFs) that could influence the ERP implementation during and after implementation phases. Some of the …

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 …

Native Language Adaptation To Novel Verb Argument Structures By Spanish-English Bilinguals: An Electrophysiological Investigation, Eve Higby

Dissertations, Theses, and Capstone Projects

Bilinguals have to learn two different grammatical systems. Some aspects of these grammars may be similar across the two languages (for example, the active-passive alternation) while others may exist in only one of the two grammars (for example, the distinction between recent and distant past). This dissertation investigates the degree to which grammar information specific to only one language is available when processing the other language. In particular, the current study focuses on the application of grammatical structures from the bilinguals’ second-learned language to their first-learned language, a direction of language transfer not often investigated. Based on a Shared Syntax …

An Erp Study Of Sensory-Linguistic Processing In The Context Of Asd Research, Larissa R. Miller

Dissertations, Theses, and Capstone Projects

This thesis considers the questions of what is hindering the language development of children with Autism Spectrum Disorder (ASD). Tomasello’s (2003) theory of language development by use necessitates adequate pattern recognition, intention reading and use for language development. Within these areas there are many variables where language acquisition could become derailed, from basic attention, perception and memory to higher cognitive functions, as well as processing speed and synchronization. Although there is a wide range of language abilities for children on the autism spectrum, the one consistently under developed area is pragmatics. One of the key aspects of pragmatic processing is …

Hormonal Correlates Of P50 Suppression In Socially Anxious Young Adults, Andrea M. Tountas

University of New Orleans Theses and Dissertations

Ten to 15% of the population is temperamentally shy and have elevated physiological stress responses to novel social situations. Yet, the neural mechanisms underlying this personality trait are not fully understood (Beaton et al., 2009; Schmidt et al., 1997). Efficiently attending to, acting on, and remembering relevant stimuli and filtering out less important information is critical given the sheer volume of sensory and perceptual stimuli the brain is exposed to.

Relevant stimuli that garner attention are remembered and consolidated with existing memories. Stimuli that do not warrant extended attention are ignored or habituated to in a process underpinned by cortical …

Three Essays On The Effects Of Appraisal, Cultural, Emotional, And Cognitive Factors On Information Technologies Acceptance And Use, Chun-Lung Huang

Theses and Dissertations

In essay 1, we propose a model, which utilized Lazarus and Folkman’s Cognitive Appraisal Theory of Emotion or Appraisal Theory (1984, 1987) as a structural foundation to lay out the nomological relationships among a person’s personal, cognitive, and emotional factors in predicting technology use behaviors. Emotion, likes many social and psychological factors, is challenging to give a full-consensus definition, and has been treated as a polar counterpart of cognition. Lazarus and Folkman’s Appraisal Theory suggested that when a person is facing a (disruptive) event, he or she appraises the possible outcomes (we suppose that appraising is a form of cognitive …
