Emotional and temporal order effects - a comparison between word-cued and important autobiographical memories recall orders.

The retrieval mechanisms associated with the recall of autobiographical memories (AMs) may differ according to the cueing method used to elicit AMs. In the present study, we provide a systematic comparison between word-cued and important AMs in terms of two recall order effects, namely a temporal and an emotional order effect. The sample comprised 104 adults aged between 59 and 90 years. On two measurement occasions, participants recalled up to 20 word-cued and 15 important AMs. For each memory, participants provided their age at the time when the event occurred (age-at-event) and rated its emotionality. Order effects were analysed based on multivariate multilevel model with autoregressive effects for emotionality and age-at-event, respectively. Whereas word-cued AMs showed a stronger emotional order effect, important AMs were recalled temporarily ordered. Individuals differed in the extent to which they ordered AMs along a temporal or emotional dimension. These differences could partly be explained by personality traits. For instance, higher scores on neuroticism were associated with a stronger emotional order effect in both memory types. Findings are discussed in terms of the retrieval mechanisms that are involved in the recall of word-cued and important memory recall and how they may be affected by personality.

How reminiscing about deceased close others together with continuing bonds relates to grief severity and personal growth: a cross-sectional study with bereaved adults.

OBJECTIVES: One of the reasons why people engage in reminiscences about their past is to maintain intimacy with deceased close others. Although previous research alerts to the negative effects of reminiscence for intimacy maintenance on mental health, little is known about its relation to individuals' reactions to loss (i.e. grief severity and personal growth). In two samples, we focus on time since loss and continuing bonds, to elucidate the role of reminiscence for intimacy maintenance in grief. METHOD: The samples comprised 111 and 198 bereaved adults. All participants rated the frequency of reminiscence for intimacy maintenance and loss-related variables, such as time since loss, continuing bonds, and grief severity. Sample 2 additionally completed measures of personal growth, loss-centrality, and their interconnectedness with the deceased. RESULTS: Reminiscence on intimacy maintenance was positively related to grief severity. This relation was independent of time since loss and partly driven by externalized bonds. Internalized bonds mediated the relation between reminiscence for intimacy maintenance and grief severity (in sample 1) and personal growth (in sample 2). CONCLUSION: Continuing bonds help explain why reminiscing for intimacy maintenance can be harmful in terms of grief severity but also fosters personal growth after the loss.

Adaptive and harmful autobiographical remembering after the loss of a loved one.

Objectives: Remembering one's personal past serves psychosocial functions. Adaptive use of autobiographical memory is related to well-being but little research has focused on grief. We address this in two studies theoretically grounded in the model of reminiscence and health.Method: Participants were adults who were actively grieving, and in both studies, completed the Reminiscence Functions Scale and grief-related measures (i.e. feelings of grief, positive changes in life perspective). Study 1 focused on uses for generally recalling one's past and Study 2 on uses of memories of the deceased.Results: Across studies, self-negative ways of remembering were associated with stronger feelings of grief and also mediated relations between social ways of remembering and grief. Self-positive ways of remembering the deceased (Study 2) were associated with having experienced positive changes in life perspective since the loss.Conclusion: The discussion focuses on how memories of one's personal past are linked to the experience of loss, even years into bereavement.

Themes of trust, identity, intimacy, and generativity in important autobiographical memories: Associations with life periods and life satisfaction.

INTRODUCTION: Guided by Erikson's theory of psychosocial development, the present study investigated whether themes of trust, identity, intimacy, and generativity are represented in older adults' most important autobiographical memories. Furthermore, we tested whether these themes are associated with certain life periods and whether having important memories (i.e., life story) that reflect developmental themes and are evaluated as positive is associated with life satisfaction. METHODS: One hundred and twelve (59.8% female) older adults (61-92 years, M = 70.96, SD = 6.81) reported up to 15 important autobiographical memories. Participants rated each memory according to the themes of trust/mistrust, identity/confusion, intimacy/isolation, and generativity/stagnation. RESULTS: Using multilevel multinomial logistic regression, we found childhood memories to be associated with trust, memories from participants' youth with identity and intimacy, and adulthood memories with intimacy and generativity. Moreover, participants who rated their autobiographical memories (i.e., life story) as high in reflecting themes and, at the same time, perceived their memories as more positive showed higher levels of life satisfaction. CONCLUSION: Important autobiographical memories reflect how an individual became the person of today. They refer to age-related themes of psychosocial development and are associated with a person's life satisfaction if they are also considered as emotionally more positive.

Personal reminiscence styles and adaptation to bereavement: how meaning mediates their relationship.

OBJECTIVES: Personal reminiscence styles are known to influence a person's well-being, but research regarding their impact on bereavement outcomes is limited. Based on previous findings, we assumed ruminative and reflective reminiscence styles to be associated with feelings of grief and personal growth, and that meaning-making efforts and the degree of having meaning-made of losing a loved one potentially mediate these relationships. METHODS: The final study sample consisted of 198 participants aged between18 and 75 years (Mage = 40.58, SD = 39.0), 83.3% were female. In a first step, we ran separate mediation models to examine the associations between reminiscence styles, processes of making meaning of the loss and bereavement. Based on these results, we build a parsimonious, inclusive pathway model. RESULTS: Our findings indicate that a ruminative reminiscence style is related to feelings of grief and personal growth through its associations with meaning-made. A reflective reminiscence style, in contrast, is associated with feelings of grief through its relation to meaning-making efforts. Moreover, a reflective reminiscence style is directly related to personal growth. CONCLUSION: Findings are discussed regarding their implications for both areas of research - autobiographical remembering and adaptation to bereavement, as well as their applicability in clinical settings.

Bringing Order to Life: Temporal Order Effects during the Recall of Important Autobiographical Memories in Young and Old Adults.

OBJECTIVE: The present study investigated whether younger and older adults differ in the extent to which they order their important autobiographical memories (AMs) in a chronological way during recall. Moreover, the number of autobiographical memories to be recalled was systematically varied in order to examine whether manipulating the size of the search sample affects the use of a chronological recall strategy. METHODS: Data come from 118 younger adults (M = 23.12, SD = 3.33) and 124 older adults (M = 69.79, SD = 8.94) who recalled either seven or thirteen important AMs. RESULTS: Using multilevel linear growth models, a temporal order effect for younger and older adults was found. For older adults, the temporal order effect was much more pronounced. The number of recalled events, however, did not affect the temporal order effect. CONCLUSION: Our findings point to a higher need for a structured search or a stronger engagement in autobiographical reasoning processes in older age. Furthermore, asking for important AMs encourages participants to provide a comprehensive overview of their life independent of the number of important AMs to be recalled.

A multilevel factor analysis of the short form of the Centrality of Event Scale.

Introduction: The Centrality of Event Scale (CES) has frequently been used to measure the degree to which positive and negative life events are perceived central to a person's identity and life story; and previous research suggests that individuals rate their most positive memory as more central compared to their most negative one. When comparing the centrality of two (or more) memories within individuals, one needs to ensure that the CES (or its short form) is equally valid for different types of events (i.e., positive and negative) as well as on different levels of analyses (i.e., on the between-person and the within-person level), pointing to the issue of measurement invariance. Methods: Three-hundred sixty-five adults (18-89 years of age) reported up to ten positive and up to ten negative autobiographical memories. For each memory reported, participants completed the seven-item short form of the CES, which measures three different components of centrality: Events can form a central component of identity (two items), a turning point in the life story (three items), and a reference point for everyday inferences (two items). Results: Based on exploratory and confirmatory factor analyses, we found a two-factor structure (Self-Perception and Life-Course) to fit the data best at both levels of analyses and for both positive and negative events. Strict measurement invariance could be applied for positive and negative events at between-person level and at within-person level. The two factors, which measure the impact of an event on either a person's self-perception or their (future) life course, were rated higher for positive compared to negative memories. This difference, however, was stronger for the self-perception factor. Discussion: The present study provides a first examination of the factorial structure of the CES short form on two levels (within and between persons) as well as for two types of life events (positive and negative). Whereas, a unidimensional scale might be sufficient to measure the centrality of stressful or traumatic life events, a more fine-graded measure seems better suited to understand the different roles of positive and negative life events for a person's identity and life story.

Maintaining intimacy during the COVID-19 pandemic.

The present study investigated whether autobiographical memories serve to maintain feelings of intimacy in times of social isolation that result from the restrictions related to the COVID-19 pandemic. Data came from 104 young and older adults who reported three important and three social memories, that is, memories about someone the participants were unable to meet because of the pandemic-related restrictions. Our findings support that social memories more frequently serve intimacy functions than important memories do, and this difference is more pronounced for older compared to young adults. Moreover, social loneliness is associated with less frequent use of important memories for intimacy functions, whereas emotional loneliness shows a positive association. Results are discussed in terms of what type of memories can be used to maintain intimacy feelings across age groups and regarding qualitative and quantitative aspects of loneliness that differently predict the use of memories for intimacy functions.

How do we recall the story of our lives? Evidence for a temporal order in the recall of important life story events.

Based on the chronological nature of extensive life narratives, in two studies, we investigated whether a temporal order can also be found for the retrieval of important life story events. The data of Study 1 come from 52 older adults (Mage = 70.35, SDage = 6.09) who reported seven important events from their life. We used multilevel analysis to take into account the hierarchical structure of the data but also to investigate individual differences. Results showed a significant temporal order effect which considerably differed between persons. In further exploratory analyses using group-based modelling, we identified three groups that differed in the direction (i.e., forward and backward) and in the size of the temporal order effect. The use of life scripts was not associated with a forward temporal order. Study 2 was conceptualised as a replication study and included 88 participants (Mage = 68.60, SDage = 6.63) who recalled up to 15 important life events. The temporal order effect, as well as the three trajectories of temporarily ordering important life story events, were replicated. Again, the use of life script was not associated with a forward ordered recall. Potential explanations for a forward and backward temporal recall order are discussed.

The valence and the functions of autobiographical memories: Does intensity matter?

Autobiographical memories serve psychosocial functions in daily life and the use of memories is related to their valence. In the present study, we examined whether functions are also related to the intensity of positive and negative memories. Our sample included 110 participants (57-89 years of age). Memories were prompted with 30 emotionally neutral cue words. Participants rated the emotional quality of each memory and indicated how frequently they had recalled it for self-continuity, directing behavior, social-bonding, and mood-enhancement. We used multilevel modeling to test whether individual differences in the use of memories can explain why individuals recall different numbers of positive and negative memories as well as memories high or low in intensity. Each function revealed its specific pattern regarding valence and intensity but also regarding within-person and between-person effects. Mood-enhancement showed the strongest relations, which points to the importance of considering emotion regulation as a function of autobiographical memory.

What characterizes the reminiscence bump in autobiographical memory? New answers to an old question.

The reminiscence bump represents one of the most robust findings in autobiographical memory research. As such, it has led to a number of different explanatory accounts that aim to elucidate it. Because most of these accounts have received some empirical support, it has been assumed that they may equally contribute to the explanation of the reminiscence bump phenomenon. In the present study, we used a multilevel multinomial mixed-effects model to examine the predictive power of explanatory variables selected from different accounts simultaneously. Analyses were based on 2,813 autobiographical memories that 97 older adults aged between 60 and 88 years reported in response to 31 cue words. Overall, the predictor variables (i.e., first-time experience, importance and emotional valence) meaningfully distinguished memories from the reminiscence bump from memories from life periods before and after. These effects, however, did not always go into the hypothesized directions. In addition, results of a Commonality Analysis indicated that although the explanatory accounts considered in the present study draw on qualities of autobiographical memories (within-person effects), they might be more useful in explaining why individuals differ in the number of autobiographical memories reported from the reminiscence bump period (between-person effects). Taken together, our findings are in line with a more integrative view on the reminiscence bump that, additionally, emphasizes the individual (e.g., the life-story account).

The mood-enhancement function of autobiographical memories: Comparisons with other functions in terms of emotional valence.

In two studies, we examined the emotional valence of memories used for mood-enhancement in relation to memories serving self, social and directive functions. Our sample included a total of 263 participants aged between 45 and 82 years. In Study 1, participants recalled memories in response to 51 cue words. In Study 2, participants recalled 32 memories that served the four functions (eight memories per function). We used multilevel modeling to take into consideration the hierarchical nature of our datasets (memories nested within individuals). Study 1 showed that emotional valence was positively associated with mood-enhancement and social functions, whereas negatively related to self and directive functions. This relation was strongest for the mood-enhancement function. In Study 2, mood-enhancing memories were rated as more positive than self, social and directive memories. We discussed results in terms of the tripartite model of memory functions and proposed that mood-enhancement should represent a distinct function.

Leveling up the analysis of the reminiscence bump in autobiographical memory: A new approach based on multilevel multinomial models.

In many studies of autobiographical memory, participants are asked to generate more than one autobiographical memory. The resulting data then have a hierarchical or multilevel structure, in the sense that the autobiographical memories (Level 1) generated by the same person (Level 2) tend to be more similar. Transferred to an analysis of the reminiscence bump in autobiographical memory, at Level 1 the prediction of whether an autobiographical memory will fall within the reminiscence bump is based on the characteristics of that memory. At Level 2, the prediction of whether an individual will report more autobiographical memories that fall in the reminiscence bump is based on the characteristics of the individual. We suggest a multilevel multinomial model that allows for analyzing whether an autobiographical memory falls in the reminiscence bump at both levels of analysis simultaneously. The data come from 100 older participants who reported up to 33 autobiographical memories. Our results showed that about 12% of the total variance was between persons (Level 2). Moreover, at Level 1, memories of first-time experiences were more likely to fall in the reminiscence bump than were emotionally more positive memories. At Level 2, persons who reported more emotionally positive memories tended to report fewer memories from the life period after the reminiscence bump. In addition, cross-level interactions showed that the effects at Level 1 partly depended on the Level 2 effects. We discuss possible extensions of the model we present and the meaning of our findings for two prominent explanatory approaches to the reminiscence bump, as well as future directions.

How can individual differences in autobiographical memory distributions of older adults be explained?

The reminiscence bump phenomenon has frequently been reported for the recall of autobiographical memories. The present study complements previous research by examining individual differences in the distribution of word-cued autobiographical memories. More importantly, we introduce predictor variables that might account for individual differences in the mean (location) and the standard deviation (scale) of individual memory distributions. All variables were derived from different theoretical accounts for the reminiscence bump phenomenon. We used a mixed location-scale logitnormal model, to analyse the 4602 autobiographical memories reported by 118 older participants. Results show reliable individual differences in the location and the scale. After controlling for age and gender, individual proportions of first-time experiences and individual proportions of positive memories, as well as the ratings on Openness to new Experiences and Self-Concept Clarity accounted for 29% of individual differences in location and 42% of individual differences in scale of autobiographical memory distributions. Results dovetail with a life-story account for the reminiscence bump which integrates central components of previous accounts.

The distribution and the functions of autobiographical memories: Why do older adults remember autobiographical memories from their youth?

In the present study, the distribution of autobiographical memories was examined from a functional perspective: we examined whether the extent to which long-term autobiographical memories were rated as having a self-, a directive, or a social function affects the location (mean age) and scale (standard deviation) of the memory distribution. Analyses were based on a total of 5598 autobiographical memories generated by 149 adults aged between 50 and 81 years in response to 51 cue-words. Participants provided their age at the time when the recalled events had happened and rated how frequently they recall these events for self-, directive, and social purposes. While more frequently using autobiographical memories for self-functions was associated with an earlier mean age, memories frequently shared with others showed a narrower distribution around a later mean age. The directive function, by contrast, did not affect the memory distribution. The results strengthen the assumption that experiences from an individual's late adolescence serve to maintain a sense of self-continuity throughout the lifespan. Experiences that are frequently shared with others, in contrast, stem from a narrow age range located in young adulthood.

Differences in the use of autobiographical memory across the adult lifespan.

Current research distinguishes between self, directive and social function of autobiographical memories (AMs). To date, only few studies have investigated these functions across adulthood. The comparison of different age groups requires that the functions of AM are measured in the same way across groups (measurement invariance, MI). Additionally to the average use of AM, the factor variances and factor covariances among the three functions were examined across adulthood. In the present study, 1290 adults (aged between 17 and 93 years) completed the Thinking about Life Experiences Questionnaire (TALE), which measures the overall use of AMs for self, directive and social purposes. The sample was divided into five age groups and partial strong MI was established using multigroup confirmatory factor analysis. The results showed an increase in the factor associations as well as a decrease in the factor mean levels of all three functions across age groups. Both findings could be adequately described by linear functions of age. The factor variances were on most parts equal across age groups. These results strengthen the assumption that--from a lifespan developmental perspective--the use of AM may be aligned with relatively normative developmental tasks in a given society.
