Emotion Regulation of Events Central to Identity and Their Relationship With Concurrent and Prospective Depressive Symptoms

Dispositional emotion regulation is related to the severity and maintenance of depressive symptoms. However, whether emotion regulation specific to an event highly central for an individual’s identity is predictive of depressive symptoms has not been examined. Nonclinical participants (N = 220) reported the extent to which they employed a selection of emotion regulation strategies when recalling low- and high-centrality events. Dispositional emotion regulation and depressive symptoms were also assessed. A 7-week follow-up was conducted. High-centrality events were associated with more emotion regulation efforts. Greater brooding and expressive suppression in relation to high-centrality memories predicted concurrent depressive symptoms after controlling for event valence and dispostional emotion regulation. Effects were absent for low-centrality memories. Emotion regulation in response to high-centrality memories did not predict depressive symptoms at follow-up beyond baseline depressive symptoms. Overall, the findings showed that maladaptive emotion regulation in response to memories of high-centrality events is important for explaining depressive symptomatology.     

POSITIVE EMOTIONS ENHANCE RECALL OF PERIPHERAL DETAILS

Emotional arousal and negative affect enhance recall of central aspects of an event. However, the role of discrete emotions in selective memory processing is understudied. Undergraduates were asked to recall and rate autobiographical memories of eight emotional events. Details of each memory were rated as central or peripheral to the event. Significance of the event, vividness, reliving and other aspects of remembering were also rated for each event. Positive affect enhanced recall of peripheral details. Furthermore, the impairment of peripheral recall was greatest in memories of anger, not of fear. Reliving the experience at retrieval was negatively correlated with recall of peripheral details for some emotions (e.g., anger) but not others (e.g., fear), irrespective of similarities in affect and intensity. Within individuals, recall of peripheral details was correlated with less belief in the memory's accuracy and more likelihood to recall the memory from one's own eyes (i.e., a field perspective).     

The end point effect in autobiographical memory: More than a calendar is needed

The end point effect, an increased frequency of memories from the start and end of a period, may be due to internalised calendar representations or narrative structures. Differential predictions derived from these theories were tested in 3 studies. In Study 1, 104 students recalled 5 memories from a relationship. In Study 2, 106 students recalled 5 memories from their first term and in Study 3, 89 students recalled 3 positive and 3 negative memories from their first term. In all three studies memories were rated on phenomenology, encoding variables and rehearsal. All three studies replicated the endpoint effect, with Study 3 showing a stronger effect for positive memories. The studies showed higher rating for end point memories on phenomenology (Study 1), encoding variables (Studies 1 and 2) and rehearsal (Study 1). Generally, the results support the narrative theory and this is discussed in relation to broader theories of autobiographical memory.     

Personality traits and autobiographical memory: Openness is positively related to the experience and usage of recollections

We examined the relationship between the Five-Factor Model of personality and the experience and overall usage of autobiographical memory in two studies. In both studies we found that Openness was related to the directive and self functions of overall usage. In addition, Openness was related to the vividness, reliving, coherence, and centrality of event to the person's identity and life story of concrete memories in Study 2, whereas this was not found in Study 1. For the remaining "Big Five" personality traits the results were less consistent across studies. Neuroticism was related to the self function in Study 1, but also to the directive function as well as to negative affect of concrete memories in Study 1. Extraversion was positively related to the social function as well as to conversational rehearsal of memories in Study 1, but this was also not replicated in Study 2. Finally, in both studies there were no significant relationships with regard to Agreeableness and Conscientiousness. Overall, the findings replicate and extend previous work showing a positive relationship between Openness and the experience and overall usage of autobiographical memory, whereas the roles for the remaining "Big Five" are less clear.     

A memory-based model of posttraumatic stress disorder: evaluating basic assumptions underlying the PTSD diagnosis

In the mnemonic model of posttraumatic stress disorder (PTSD), the current memory of a negative event, not the event itself, determines symptoms. The model is an alternative to the current event-based etiology of PTSD represented in the Diagnostic and Statistical Manual of Mental Disorders (4th ed., text rev.; American Psychiatric Association, 2000). The model accounts for important and reliable findings that are often inconsistent with the current diagnostic view and that have been neglected by theoretical accounts of the disorder, including the following observations. The diagnosis needs objective information about the trauma and peritraumatic emotions but uses retrospective memory reports that can have substantial biases. Negative events and emotions that do not satisfy the current diagnostic criteria for a trauma can be followed by symptoms that would otherwise qualify for PTSD. Predisposing factors that affect the current memory have large effects on symptoms. The inability-to-recall-an-important-aspect-of-the-trauma symptom does not correlate with other symptoms. Loss or enhancement of the trauma memory affects PTSD symptoms in predictable ways. Special mechanisms that apply only to traumatic memories are not needed, increasing parsimony and the knowledge that can be applied to understanding PTSD.     

Personal memories for remote historical events: accuracy and clarity of flashbulb memories related to World War II

One hundred forty-five Danes between 72 and 89 years of age were asked for their memories of their reception of the news of the Danish occupation (April 1940) and liberation (May 1945) and for their most negative and most positive personal memories from World War II. Almost all reported memories for the invasion and liberation. Their answers to factual questions (e.g., the weather) were corroborated against objective records and compared with answers from a younger control group. The older participants were far more accurate than what could be predicted on the basis of results from test-retest studies using short delays. The "permastore" metaphor (Bahrick, 1984) provides a possible interpretation of this discrepancy. Participants with reported ties to the resistance movement had more vivid, detailed, and accurate memories than did participants without such ties. Ratings of surprise and consequentiality were unrelated to the accuracy and clarity of the memories.     

The episodic nature of involuntary autobiographical memories

Involuntary autobiographical memories are conscious and unintended recollections of personal experiences. In Study 1, involuntary memories were compared with voluntary word-cued memories, both retrieved in naturalistic settings via a self-paced procedure. The involuntary memories more frequently referred to specific episodes, came with more physical reaction, had more impact on mood, and dealt with more unusual and less positive events. Study 2 demonstrated that these differences were not due to differences between verbal and nonverbal cues, by using Francis Galton's "memory walk" as a nonverbal method to cue voluntary memories. In both studies, systematic differences were found between specific and nonspecific memories. The findings show that the way autobiographical memories are sampled greatly affects the findings and that involuntary retrieval more often provides access to memories of specific episodes and associated emotional states.
