Neural Mechanisms Of Action Switching Moderate The Relationship Between Effortful Control And Aggression, Eric L. Rawls Aug 2016

Neural Mechanisms Of Action Switching Moderate The Relationship Between Effortful Control And Aggression, Eric L. Rawls

University of New Orleans Theses and Dissertations

Aggression and violence are social behaviors that exact a significant toll on human societies. Individuals with aggressive tendencies display deficits in effortful control, particularly in affectively charged situations. However, not all individuals with poor effortful control are aggressive. This study uses event-related potentials (ERPs) to decompose the chronology of cognitive functions underlying the link between effortful control and aggression. Specifically, this study investigates which ERPs moderate the effortful control - aggression association. We examined three successive ERP components (P2, N2 and P3) for stimuli that required effortful control. Results indicated that N2 activation, but not P2 or P3 activation, moderated the ...


Emotional And Autonomic Responding To Auditory Stimuli, Jeremy C. Peres Dec 2015

Emotional And Autonomic Responding To Auditory Stimuli, Jeremy C. Peres

University of New Orleans Theses and Dissertations

Much of the research examining emotion induction, regulation, and suppression considers solely the visual modality (e.g., pictures of faces) for emotion elicitation. In reality, emotions are cued, expressed, and interpreted through multiple modalities by employing the extensive use of auditory stimuli in addition to visual stimuli. There have been some recent efforts to offset this imbalance in modality preference by using emotional auditory stimuli alone or in addition to visual stimuli. This project aims to further investigate emotional and autonomic responding to auditory stimuli with the added component of examining differential responding across social (nonlinguistic vocal expression) and non-social ...
