Self-defining memories in complicated grief

There is increasing attention to the mechanisms underpinning maladaptive responses to bereavement. This study indexed self-defining memories in bereaved individuals with and without complicated grief (CG). Participants with and without complicated grief (N = 40) were asked to describe three self-defining memories. Results showed that CG participants provided more self-defining memories involving the deceased. Both groups were equally likely to report their loved one's death as a self-defining moment, however, the no-CG group showed more evidence of benefit finding in their memory narratives and experienced less negative emotion on recall. The findings suggest that CG is associated with distinctive patterns of autobiographical memory that are linked to self-identity. The pattern is consistent with self-memory system models of autobiographical remembering, and suggests that grieving individuals who experience ongoing yearning for their loved one view their self-identity as more closely linked to the deceased are more distressed by memories involving the loss.     

Specificity in autobiographical memory narratives correlates with performance on the Autobiographical Memory Test and prospectively predicts depressive symptoms

Reduced autobiographical memory specificity (AMS) is an important cognitive marker in depression that is typically measured with the Autobiographical Memory Test (AMT; Williams & Broadbent, 1986). The AMT is widely used, but the over-reliance on a single methodology for assessing AMS is a limitation in the field. The current study investigated memory narratives as an alternative measure of AMS in an undergraduate student sample selected for being high or low on a measure of depressive symptoms (N=55). We employed a multi-method design to compare narrative- and AMT-based measures of AMS. Participants generated personally significant self-defining memory narratives, and also completed two versions of the AMT (with and without instructions to retrieve specific memories). Greater AMS in self-defining memory narratives correlated with greater AMS in performance on both versions of the AMT in the full sample, and the patterns of relationships between the different AMS measures were generally similar in low and high dysphoric participants. Furthermore, AMS in self-defining memory narratives was prospectively associated with depressive symptom levels. Specifically, greater AMS in self-defining memory narratives predicted fewer depressive symptoms at a 10-week follow-up over and above baseline symptom levels. Implications for future research and clinical applications are discussed.     

Exploring self-defining memories in schizophrenia

Previous studies have shown that patients with schizophrenia are impaired in recalling specific events from their personal past. However, the relationship between autobiographical memory impairments and disturbance of the sense of identity in schizophrenia has not been investigated in detail. In this study the authors investigated schizophrenic patients’ ability to recall self-defining memories; that is, memories that play an important role in building and maintaining the self-concept. Results showed that patients recalled as many specific self-defining memories as healthy participants. However, patients with schizophrenia exhibited an abnormal reminiscence bump and reported different types of thematic content (i.e., they recalled less memories about past achievements and more memories regarding hospitalisation and stigmatisation of illness). Furthermore, the findings suggest that impairments in extracting meaning from personal memories could represent a core disturbance of autobiographical memory in patients with schizophrenia.     

Rumination and self-defining memories in the context of health concerns

Individuals with health anxiety report experiencing a strong sense of vulnerability to illness. Such beliefs may be driven by the biased recollection of past illness-related events. However, little research has explored the role of memory in health anxiety. In other disorders, rumination has also been identified as a process that leads individuals to recall memories dominated by the content of their concerns. This study examined the proposition that rumination might impact the content of “self-defining” autobiographical memories among 60 college students with varying health anxiety (35% with clinical-level health anxiety). Participants were randomised to experiential/ruminative self-focus conditions, and then they completed the Self-Defining Memory Task. Responses were coded for valence and illness-relatedness. Results indicated that rumination led participants to retrieve more illness-related self-defining memories, while higher health anxiety scores were associated with more negative, but not more illness-focused memories. Ruminative thinking appears to activate health concerns, and may play a role in maintaining ongoing health anxiety.     

Gender differences in emotional experiences across childhood,romantic relationship,and self-defining memories

The aim of the present study is to examine the gender differences in emotional experiences across three different types of autobiographical memory. A total of 612 undergraduate students from Izmir, Turkey, were asked to recall a memory either from childhood, from romantic relationships, or from self-defining experiences. A gender difference was found in the intensity of anxiety, sadness, and pride for romantic relationship memories. Men had higher scores on emotional distancing than women in self-defining memories. With regard to emotional valance, women’s feelings were less positive than men’s feelings when remembering childhood and romantic relationship experiences, whereas they were more positive than men’s feelings when remembering self-defining experiences. The findings support the notion that gender differences in emotional experiences during the autobiographical recollection of personal life events vary across different memory types.     

Recalling positive self-defining memories in depression: The impact of processing mode

Recalling positive memories is a powerful and effective way to improve mood. However, unlike never-depressed individuals, those with current or past depression do not benefit emotionally from positive memory recall. To examine whether rumination is involved in this difficulty, 80 participants (26 currently depressed, 29 recovered depressed, and 25 never depressed) were instructed to recall a positive self-defining memory while in a sad mood. They were then instructed to think about their memory, adopting either an abstract or concrete processing mode. Never-depressed and recovered depressed participants experienced improved mood after memory recall, regardless of processing mode. However, for depressed individuals neither an abstract nor a concrete processing mode produced emotional benefit. These findings suggest that a complex relationship exists among processing mode, memory type, and depressive status, and indicate that the way in which individuals process positive emotional material may have important consequences for treatment.     

Four dimensions of self-defining memories (specificity, meaning, content, and affect) and their relationships to self-restraint, distress, and repressive defensiveness

This study examines four dimensions of self-defining memory (specificity, meaning, content, and affect) and their relationship to self-restraint, distress, and defensiveness. The development and validation of a protocol for measuring specificity, meaning, and affect in self-defining memories is discussed. Specificity is operationalized as the temporal and detailed specificity of the narrative. Meaning refers to the participant's stepping back from the narrative to derive higher personal meaning or a life lesson. Affect reflects subjective emotion upon recall. Agreement between two raters scoring 1040 memories was kappa=.83 for specificity and kappa=.72 for meaning. The protocol is compatible with Thorne and McLean's scoring system for content (the types of events in memories). The current study compared individual differences in the four dimensions of 10 self-defining memories collected from 103 undergraduates to scores of self-restraint, distress, and repressive defensiveness, as measured by the Weinberger Adjustment Inventory. Memory specificity was inversely related to repressive defensiveness, while greater memory meaning was linked to moderate and high levels of self-restraint. Memory content and affect predicted individuals' degree of subjective distress. Based on these findings, the authors discuss the place of self-defining memories in Conway and Pleydell-Pearce's Self-Memory System model of autobiographical memory and personality, more generally.     

Late adolescents' self-defining memories about relationships

This study examined late adolescents' self-defining memories about relationships. Participants were 88 European Americans (mean age = 19 years) who reported 3 self-defining memories of their choosing and were selected for the study because they reported a memory about parents and/or peers. Memory narratives were coded for themes of separation, closeness, and conflict and for 2 kinds of meaning: learning lessons and gaining insight. Parent memories emphasized separation more so than peer memories, which emphasized closeness. Within parent memories, however, separation and closeness were equally prevalent. Parent separation was exemplified by experiences of parental divorce, parent closeness by comforting a grieving parent, and peer closeness by episodes of first-time romance. Conflict was more prevalent in parent than peer memories and was associated with meaning-making. Findings are discussed in terms of the usefulness of self-defining memories for illuminating contexts of relationship development in late adolescence and for understanding the emergence of identity and the life story.     

Subjective impact, meaning making, and current and recalled emotions for self-defining memories

Two studies examined the impact of self-defining events on individuals (i.e., subjective impact), meaning making with regard to these events, and how subjective impact may account for the pattern of current and recalled emotions for these self-defining memories (Singer & Moffitt, 1991-1992). In Study 1, participants recalled self-defining memories, indicating how much impact the recalled events have had on them and described meaning making for these events. Subjective impact was shown to be a good marker for meaning making. Participants in Study 2 each recalled five self-defining memories, reporting their current emotions about the events, the emotions they recalled feeling at the time, and the impact the events have had on them. As expected, for negative memories, people reported less negative emotion (e.g., sadness) and more positive emotion (e.g., pride) compared to how they recalled feeling at the time. For positive memories, people reported equally intense positive emotion (e.g., love) and less negative emotion (e.g., fear) compared to how they recalled feeling at the time. These patterns of current and recalled emotions were accounted for by impact ratings.     

Networks of self-defining memories as a contributing factor to emotional openness

Emotional openness is characterised by a capacity to tolerate threatening self-relevant material and an interest towards new emotional situations. We investigated how specific networks of memories could be an important contributing factor to emotional openness. At Phase 1, participants completed measures of personality traits and emotional intelligence, described a self-defining memory, provided other memories associated with it, and rated the valence of each of their memories. A score assessing the complexity of this memory network, comprising the number of memories reported and their valence diversity, was created. Two weeks later, in laboratory, participants watched an anxiety-inducing film and took part in an interview assessing their emotional openness to the film. They completed a cognitive task before and after the film to measure ego depletion. Controlling for traits and emotional intelligence, memory network complexity was positively associated with emotional openness and negatively with ego depletion. The mental organisation of self-defining memories thus appears to be a critical factor contributing to emotional openness.

Contribution of past and future self-defining event networks to personal identity

Personal identity is nourished by memories of significant past experiences and by the imagination of meaningful events that one anticipates to happen in the future. The organisation of such self-defining memories and prospective thoughts in the cognitive system has received little empirical attention, however. In the present study, our aims were to investigate to what extent self-defining memories and future projections are organised in networks of related events, and to determine the nature of the connections linking these events. Our results reveal the existence of self-defining event networks, composed of both memories and future events of similar centrality for identity and characterised by similar identity motives. These self-defining networks expressed a strong internal coherence and frequently organised events in meaningful themes and sequences (i.e., event clusters). Finally, we found that the satisfaction of identity motives in represented events and the presence of clustering across events both contributed to increase in the perceived centrality of events for the sense of identity. Overall, these findings suggest that personal identity is not only nourished by representations of significant past and future events, but also depends on the formation of coherent networks of related events that provide an overarching meaning to specific life experiences.     

Effects of children's emotional state on their reactions to emotional expressions: A search for congruency effects

Abstract

Three groups of 30 six-year-old children were tested to examine whether one's own happy or sad mood state causes a specific preference for happy or sad expressions in others, a systematic bias in the labelling of ambiguous expressions, and a selective memory for happy or sad expressions. In two of these groups, a happy or sad mood state was induced by a mental imagery procedure. The third group served as control subjects. It was found that all groups showed a distinct preference for happy faces. Happy children, however, tended to opt for extremely happy faces, whereas sad children chose mildly happy expressions. Furthermore, children (especially the children that received a happy mood induction) were inclined to interpret ambiguous expressions as being congruent with their own mood state. Finally, the “sad” group recalled fewer expressions correctly than the other two, irrespective of the nature of these expressions. Overall, the happy face was more often correctly identified than the sad one.     

Older, wiser, and happier? Comparing older adults' and college students' self-defining memories

The present study compared self-defining memories in adults 50 years of age and older to the self-defining memories of college students. Findings are largely congruent with previous memory and ageing research, but shed additional light on how personal memories are employed to achieve a sense of identity and continuity in older adults. Older adults' self-defining memories, compared to those of younger adults, were more positive in emotional tone, more summarised and less detailed, and more likely to contain integrative meaning. The implications of these findings for assessing normative personal memory in older adults are discussed along with more general observations about narrative identity in older adulthood.     

Longitudinal directive effect of need satisfaction in self-defining memories on friend related identity processing styles and friend satisfaction

Research suggests that identity and memory are deeply interconnected, but little is known about the identity processes and the memory characteristics involved in this interaction. We employed a longitudinal design to examine relations between the satisfaction of autonomy, relatedness, and competence needs in self-defining memories and identity processing styles within the domain of friendship. We also assessed satisfaction with friends to evaluate the relation of identity processes and memory characteristics to well-being in friendships. Participants were 166 students who responded twice (at about a two-year interval) to the Identity processing style Inventory-3 and the Satisfaction with Life Scale. We adapted these measures to tap into the domain of friendships, which is an important aspect of young adults’ identity. Participants also described a friend-related self-defining memory and rated the degree of need satisfaction they experienced in that event. A cross-lagged panel analysis revealed that memory need satisfaction predicted increases in informational identity processing style and friend satisfaction over time. Implications for the directive function of memory in identity are discussed.     

Connecting the self to traumatic and positive events: links to identity and well-being

Self-event connections in autobiographical narratives help integrate specific episodes from memory into the life story, which has implications for identity and well-being. Previous research has distinguished differential relations between positive and negative self-event connections to psychological well-being but less research has examined identity. In this study, examining self-event connections in emerging adults’ narratives, 225 participants narrated a traumatic and an intensely positive experience and completed questionnaires assessing identity development and well-being. Participants who described more negative connections to self overall had higher psychological distress and identity distress, compared to those who described fewer negative connections. Participants who described positive connections to the self in traumatic events were more likely to have lower psychological distress, higher post-traumatic growth, and higher identity commitment, whereas positive connections in positive events was related to higher identity exploration and marginally higher post-traumatic growth. These findings contribute to a growing body of literature that suggests linking autobiographical memories to self can have differential effects on identity and well-being depending on the valence of the event and the connections made.     

The role of lifetime periods in the organisation of episodic memories

ABSTRACT

Research on the nature of episodic memory associations has suggested that episodic memories are associated by conceptual knowledge, where memories cluster around the same content (e.g. memories about the same people) or general-event knowledge, where memories cluster around extended events (e.g. a holiday in London), repeated events (e.g. Sunday walks in the park), or causally related events (i.e. where one event leads to another). Research has also suggested that episodic memories are associated by lifetime periods (e.g. when I was in high school), where memories cluster within lifetime periods. However, it is unclear whether episodic memories can be associated solely by lifetime periods, or if such associations are subordinate to conceptual or general-event associations. To answer this question, we reanalysed a large sample of involuntary memory chains (Mace, J. H., Clevinger, A. M., & Bernas, R. S. (2013). Involuntary memory chains: What do they tell us about autobiographical memory organisation? Memory, 21, 324–335). The results of this analysis suggested that lifetime periods associations are subordinate to conceptual and general-event associations, as lifetime periods were found to cluster within the latter two associations. The potential functions of this organisation are discussed.     

Older,wiser, and happier? Comparing older adults’ and college students’ self-defining memories

The present study compared self-defining memories in adults 50 years of age and older to the self-defining memories of college students. Findings are largely congruent with previous memory and ageing research, but shed additional light on how personal memories are employed to achieve a sense of identity and continuity in older adults. Older adults’ self-defining memories, compared to those of younger adults, were more positive in emotional tone, more summarised and less detailed, and more likely to contain integrative meaning. The implications of these findings for assessing normative personal memory in older adults are discussed along with more general observations about narrative identity in older adulthood.
