"Where were you when...?" : the interaction of the personal and the historical in the Challenger explosionClearwater, David A. January 1998 (has links)
This thesis explores the problems associated with an individual's interpretation of historical events; especially through a question such as "Where were you when you heard the news of the Challenger explosion?" Remembering an event in this manner implies that both a physical and temporal distance exists between an individual watching from afar and the event in question. This distance indicates that the event is never transparent nor is its meaning self-evident; it unfolds over time and is rendered almost incomprehensible through the proliferation of language and discourse surrounding the event, the fragmentary nature of its remnants, and the fallibility of both individual memory and the historical record. But instead of making the event meaningless, notions of 'distance' and 'incomprehensibility' provide a space where an event's meaning is most understandable for an individual. Beginning with Wittgenstein's Tractatus and ending with Barthes' A Lover's Discourse, I would like to show how little separates the philosopher attempting to understand the world, the historian interpreting the historical record, the amorous subject deciphering the signs and gestures of an absent or unattainable lover, and the individual remembering a historical event.

Consistency, Consolidation, and Cognition in Autobiographical Memories: a Flashbulb Memory ApproachKraha, Amanda 05 1900 (has links)
Flashbulb memories are highly vivid and long-lasting memories for events that are emotionally significant and personally important. These memories are held in very high confidence in accuracy over an extended period. In particular, individuals believe that they can remember the personal details surrounding the event such as where they were and what they were doing at the time the event occurred. Evidence from research, however, indicates that this may not be the case. The study of flashbulb memories has typically been confined to negative events such as September 11, 2001. In the current study, we employ the methods of Talarico and Rubin (2003) to investigate flashbulb memory formation to a positive event. The event is the assassination of Osama bin Laden, which resonated as a highly positive event for many Americans evidenced by the thousands of people flooding the streets of Washington, D.C. and New York City to celebrate. We examined various memory properties over a one-year period, including vividness, rehearsal, belief in accuracy, and consistency. Results confirm the formation of flashbulb memories to the assassination event, but results did not support many of the proposed hypotheses. Some differences were found for different testing groups (i.e., immediate versus one week delay), but these were not replicated at the one year follow-up. Overall, however, it is believed that the current event, while still a flashbulb memory, was not a strong enough event to stir strong emotions and form memories on par with 9/11.

Influence of Temporary Inactivation of the Prefrontal Cortex or Hippocampus during Stress on the Subsequent Expression of Anxiety and MemoryHalonen, Joshua D 04 March 2009 (has links)
The neural pathways underlying the symptoms of Post Traumatic Stress Disorder (PTSD) have not been fully elucidated. Intrusive memories, persistent anxiety and other cognitive deficits have been attributed to maladaptive or otherwise aberrant processing in specific brain regions, including the hippocampus, amygdala and prefrontal cortex. Our laboratory has developed an animal model of PTSD which results in the enhancement of memory for a place associated with exposure to a predator, anxiety-like behavior, increased startle and impaired memory in a non-aversive memory task. To better understand how the interaction of the hippocampus and prefrontal cortex contribute to the different symptoms of the disorder, we investigated the transient inactivation of each structure during an intense stressor. Our results show that long-term contextual fear associations involve activity in both the hippocampus and the prefrontal cortex, but only the prefrontal cortex is involved in cued fear memories as well.

Down memory lane : a mixed method investigation of the reminiscence bump in the dynamics of autobiographical memoryVenter, Anelien 01 1900 (has links)
Research into the reminiscence bump aims to improve our understanding of how the memories formed during our adolescence and early adulthood subsequently influence our autobiographical recollections later in life. The purpose of this study was to investigate the temporal dynamics of autobiographical memory in a sample involving two different age groups of adult South African participants. The main objective of the research was to explore the participants’ memories for salient events and to determine whether these memories exhibit the typical reminiscence bump that has been found in autobiographical memory research.
This sample consisted of two sets of cohorts, totalling 48 research participants. The first group comprised participants ranging between the ages of 40 and 59 years, and the second group involved participants ranging between the ages of 60 to 79 years. A convergent parallel mixed method approach was adopted in this study. Both quantitative and qualitative data, on the distribution, valence and life domain importance of the reminiscence bump, were collected through the lifeline interview method. The results confirmed that reminiscence bumps are reflected in the memories of both age groups between the ages of 10 and 30 years. Most life events recalled were of positive affect thus confirming the positivity bias in older adults. The family and home life domains were indicated as the most important life domains in the autobiographical memories of both groups.
The main conclusion drawn from the study was that there was not a significant difference in the dynamics of the autobiographical memories between the two groups, as reflected in the temporal characteristics of their reminiscence bumps. Future research could further explore the patterns of memories, and researchers could in particular investigate the semantic and affective aspects of these autobiographical memories in more depth. / Psychology / M.A. (Psychology)
