Involuntary Memories After Stressor Exposure: Contribution Of Hormonal Status And Rumination In Women., Samantha C. Patton
Involuntary Memories After Stressor Exposure: Contribution Of Hormonal Status And Rumination In Women., Samantha C. Patton
Electronic Theses and Dissertations
Women experience fewer traumatic stressors over their lifespan than men, but demonstrate a higher prevalence of major depression and stressor-related disorders as a result of trauma exposure (Breslau & Anthony, 2007; Kessler et al., 2005). Differences in prevalence of stressor-related disorders may partially be due to sex-linked vulnerabilities related to emotional memory. Emotion assists in modulation of memory through neurological processes. This modulation enhances memory for emotional stimuli and can lead to a greater frequency of involuntary recall after stressor exposure. This involuntary memory is also a hallmark symptom of Posttraumatic Stress Disorder (PTSD). Sex-linked vulnerabilities, specifically hormonal status and …
Effects Of Context And Individual Differences On Memory For Prior Remembering., Marcus L. Leppanen
Effects Of Context And Individual Differences On Memory For Prior Remembering., Marcus L. Leppanen
Electronic Theses and Dissertations
Though people often remember experiences from their lives, they are also able to remember whether a memory has previously been retrieved, which is known as memory for prior remembering. Frequent failures of memory for prior remembering can have negative consequences on how people perceive their own cognitive health. The recurrence of traumatic memory retrieval can be interpreted as a consequence of intrusive memory for prior remembering. This dissertation was conducted to improve our understanding of the factors that influence the efficacy of memory for prior remembering. The two factors that were investigated were context change and individual differences. Participants ( …

A Fly Has Died A Splendid Death In A Pool Of Strawberry Ice Cream., Miranda L. Becht
Electronic Theses and Dissertations
Humans have evolved an overwhelming awareness of self, other, life, and death. We have learned to selectively process information and to replace dissociated memories with less disturbing ones. We have evolved this ability to deceive ourselves, thus producing a personal reality that is innately false. As a society we tend to idealize our vision of the past, particularly our vision of home. Our idealized notion of home presents itself as a supposedly traditional form of domestic life, but bears little relation to the way people actually lived. This concept of a cozy home full of family love is an invented …
Testing Location Memory For Threatening And Nonthreatening Stimuli : Implications For Evolutionary Psychological Theorizing., Ryan Patrick Hacklander
Testing Location Memory For Threatening And Nonthreatening Stimuli : Implications For Evolutionary Psychological Theorizing., Ryan Patrick Hacklander
Electronic Theses and Dissertations
Humans respond to the presence of threatening stimuli more rapidly than nonthreatening stimuli, a trait that some authors believe humans have been selected for. Based on this finding, it has been proposed that humans should also have superior location memory for threatening stimuli, possibly depending on whether stimuli have ancestral (e.g., snakes) or modern (e.g., guns) ecological relevance. This is herein called the Superior Location Memory for Threatening Stimuli (SLMTS) hypothesis. Some authors believe that humans possess a domain-specific adaptation that gives rise to the hypothesized memory advantage for threatening stimuli. The primary aim of this dissertation is to test …
Deconstructing Saccades : Identifying The Components Of Saccades That Produce Saccade-Induced Retrieval Enhancement., James Matthew Edlin
Deconstructing Saccades : Identifying The Components Of Saccades That Produce Saccade-Induced Retrieval Enhancement., James Matthew Edlin
Electronic Theses and Dissertations
Multiple studies have found that performing repetitive saccades for 30 s improves subsequent memory retrieval. Although the effect is well established, the mechanism by which saccades affect retrieval is currently unknown. Saccade-induced retrieval enhancement (SIRE) has been hypothesized to be a product of increasing: interaction between the hemispheres, interaction within the hemispheres, or attentional control. It is currently unknown which components of the saccade activity are necessary to produce SIRE. The saccade activity in previous SIRE research is similar to an orienting activity that produces predictive saccades. Predictive saccades begin as exogenous orienting to a rhythmically alternating target. After a …
