Consistency, Consolidation, and Cognition in Autobiographical Memories: a Flashbulb Memory Approach (open access)

Consistency, Consolidation, and Cognition in Autobiographical Memories: a Flashbulb Memory Approach

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 …

Response to Sexual Trauma in Relation to Event Centrality and Objectified View of Self (open access)

Response to Sexual Trauma in Relation to Event Centrality and Objectified View of Self

This study examined the potentially differing emotional consequences of sexual versus non-sexual traumas in both a student and a community residing treatment seeking sample of women. The extent to which a trauma survivor considers the traumatic event central to her identity (CES) was examined as a potential mediator between traumatic events and PTSD. Additionally, the extent to which a women views herself and her body as a sexual object, to be valued based on her appearance and sexual usefulness to others (sexual self-objectification: OBCS), was examined as a potential mediator between traumatic event and event centrality. Study results showed survivors of sexual assault reported greater CES and PTSD symptoms (PCL-S) than non-sexual trauma survivors in the student population. Mediation results showed sexual self-objectification (OBCS-Shame) significantly mediated the relationship between trauma type and CES, and CES significantly mediated the relationship between type of trauma and PTSD symptoms in the student population only. Data from the community sample did not support these conclusions as women from this sample reported higher PCL-S, CES, and OBCS-Shame scores across categories of trauma.

When the Levee Breaks: An SEM Approach to Understanding the Narrative and the Anxiety-Buffer Disruption on PTSD Symptoms (open access)

When the Levee Breaks: An SEM Approach to Understanding the Narrative and the Anxiety-Buffer Disruption on PTSD Symptoms

The purpose of the present study was to assess if combining the two frameworks would account for more variance in PTSS than could be accounted for using the frameworks separately. An online community sample from Amazon.com's Mechanical Turk (N = 437), who reported experiencing a prior traumatic event, completed measures that reflected the constructs of narrative centrality, negative affectivity, and death concerns, along with a measure of PTSS. PTSS was regressed on the latent variables of death concerns, narrative centrality, and negative affectivity, along with the latent variable interactions between narrative centrality*death concerns and narrative centrality*negative affectivity. Death concerns was not be predictive of PTSS, whereas narrative centrality and negative affectivity were found to uniquely and interactively account for 77% of the variance in PTSS. Death concerns was found to be a separate construct from negative affectivity. The implications of these findings for the two frameworks are discussed along with future directions. By considering aspects of narrative centrality and negative affectivity, substantial portions of PTSS can be accounted for.

Bidirectional Effects Between Engaged Lifestyle and Cognition in Later Life: Exploring the Moderation Hypothesis for Personality Variables. (open access)

Bidirectional Effects Between Engaged Lifestyle and Cognition in Later Life: Exploring the Moderation Hypothesis for Personality Variables.

Longitudinal data (N = 263) was used to investigate the bidirectional relationship between engagement (engaged lifestyle activities) and cognition (crystallized & fluid intelligence). Extroversion and openness to experience were also tested as moderators of the relationship between engagement and cognition. Results showed that the relationship between engagement at Wave 1 and cognition at Wave 2 did not differ from the relationship between cognition at Wave 1 and engagement at Wave 2. Testing for moderation with regression indicated that neither extroversion nor openness was moderating the relationship between engagement and cognition in either direction. Structural equation models provided further summary evidence that the relationships among engagement at Wave 1, extroversion, openness, and cognition at Wave 2 were not strong. However, a strong limitation to these results was the measurement error associated with a new measure of engagement.

An Examination of a Framework for Posttraumatic Stress Disorder Correlates: Exploring the Roles of Narrative Centrality and Negative Affectivity (open access)

An Examination of a Framework for Posttraumatic Stress Disorder Correlates: Exploring the Roles of Narrative Centrality and Negative Affectivity

Recent estimates suggest that a large percentage of the population experiences some type of traumatic event over the course of the lifetime, but a relatively small proportion of individuals develop severe, long-lasting problems (e.g., posttraumatic stress disorder; PTSD). One major goal for trauma researchers is to understand what factors contribute to these differential outcomes, and much of this research has examined correlates of posttraumatic stress disorder (PTSD) symptom severity. An important next step in this line of research is the development of conceptual frameworks to foster a deeper understanding of the relationships among these diverse predictors of PTSD and their predictive power in relation to each other. A framework proposed by Rubin, Boals, and Hoyle centers on the influence of narrative centrality (construal of a traumatic experience as central to one's identity and to the life story) and negative affectivity (the tendency to experience negative emotion and to interpret situations and experiences in a negative light), suggesting many variables may correlate with PTSD symptoms via shared variance with these two factors. With a sample of 477 participants recruited from Amazon Mechanical Turk, this dissertation project extended the work of Rubin and colleagues by a) utilizing structural equation modeling techniques to …
