Mental Imagery In The Regulation Of Differential Fear Conditioning: A Multimodal Investigation Involving Self-Report, Psychophysiology, And Brain Imaging, Tyler Daniel Robinson
Mental Imagery In The Regulation Of Differential Fear Conditioning: A Multimodal Investigation Involving Self-Report, Psychophysiology, And Brain Imaging, Tyler Daniel Robinson
LSU Doctoral Dissertations
Mental imagery is a common component in a range of emotion regulation techniques. However, the effectiveness and neural mechanisms of regulation via mental imagery are underexplored due to a lack of studies targeting mental imagery specifically. This discrepancy results in uncertainty regarding the mechanism of regulation in existing paradigms. Biased competition for attentional resources presents a plausible model by which a mental imagery-based distracter can downregulate response to an emotional stimulus. If visualizing an imagined distracter effectively regulates emotional response, the inclusion of mental imagery components in other techniques represents a potential confound. To address this discrepancy, this dissertation investigates …
Attentional Deployment, Cognitive Control, And Reappraisal In Schizophrenia, Kyle Robert Mitchell
Attentional Deployment, Cognitive Control, And Reappraisal In Schizophrenia, Kyle Robert Mitchell
LSU Doctoral Dissertations
Recent studies posit that deficits in emotion regulation may lead to increased negative emotional experience in schizophrenia. While individuals with schizophrenia evidence a number of abnormalities in emotion regulation, it is unclear whether these deficits are discrete or related; furthermore, the mechanisms underlying these deficits are not clear. Cognitive control has been posited as an important mechanism supporting emotion regulation. The current study examined the relationship between attentional deployment and both lexical and self-reported indices of reappraisal, as well as the mediating role of cognitive control on this relationship in a sample of 22 individuals with psychotic disorders. A novel …
The Effects Of Emotion And Action On Binding In Memory, Kacie Mennie
The Effects Of Emotion And Action On Binding In Memory, Kacie Mennie
LSU Master's Theses
The ability to successfully bind features and objects at different levels of abstraction is important for everyday functioning of memory. The current study examined how actions and emotional arousal influence item recognition and between-item binding across two experiments. According to the Arousal-Biased Competition Theory (ABC; Mather and Sutherland, 2011), binding can be enhanced by emotional arousal, depending upon what is the focus of attention within a scene. In the current study, participants viewed a series of slides, each of which depicted a person performing an action with an object, as well as an object that is not interacted with. All …
Emotion Recognition In Schizotypy, Laura Brown
Emotion Recognition In Schizotypy, Laura Brown
LSU Master's Theses
Deficits in social cognition are repeatedly found in individuals with schizophrenia. Facial emotion recognition is a major aspect of social cognition in which individuals with schizophrenia show consistent deficits. However, many questions about these deficits remain unanswered including whether they occur in individuals with schizotypy—those at high risk for the disorder that do not manifest full pathology. Examining emotion recognition in schizotypy eliminates many of the confounds associated with schizophrenia research such as medication effects, chronic institutionalization, and generalized cognitive deficits, and allows for the examination of whether emotion recognition deficits reflect vulnerability to schizophrenia. Prior research in this population …
The Impact Of Gruesome Evidence On Mock Juror Decision Making : The Role Of Evidence Characteristics And Emotional Response, Robert J. Nemeth
The Impact Of Gruesome Evidence On Mock Juror Decision Making : The Role Of Evidence Characteristics And Emotional Response, Robert J. Nemeth
LSU Doctoral Dissertations
Two experiments were conducted to investigate the effects of gruesome evidence on mock jurors? decisions in a simulated capital trial. The first experiment was designed as a replication and extension of Douglas, Lyon, and Ogloff (1997), who found that mock jurors who were presented with gruesome photographic evidence were nearly twice as likely to convict the defendant than participants who did not see the gruesome evidence. In Experiment 1, gruesome evidence was manipulated in two ways: photographic evidence (low gruesome, highly gruesome, or control photographs) and verbal testimony (low gruesome vs. highly gruesome). Neither photographic evidence nor testimony had an …
