RESUMO
The emotions attributed to an event can change from occurrence to recall. Autobiographical memories (AMs) exhibit fixed affect (i.e., no change in emotionality), fading affect (i.e., a decrease in emotional intensity), flourishing affect (i.e., an increase in emotional intensity), and flexible affect (i.e., change of valence). Mixed-effects multinomial models were used to predict the likelihood of the different affect change categories. Mixed-effects regression models were used to predict the amount of emotional change within each category. Predictors at the event-level were initial intensity, social rehearsal, and recall frequency. Predictors at the participant-level were components of subjective wellbeing. Analyses were based on 1,748 AMs reported by 117 young participants in response to 16 event cues. Frequency biases, and biases in the amount of change across positive and negative emotionality, were found for all types of emotional change. Specifically, there was more fading of negative (29.98%) than positive affect (11.90%), more flourishing of positive (34.27%) than negative affect (9.61%), and more AMs changing from negative to positive valence (13.33%) than vice versa (3.95%). These biases were also evident in the amount of change within the categories. Moreover, slightly more AMs remained fixed in positive (49.89%) than negative affect (47.08%). Both event and participant level predictors were significantly associated with the likelihood of different affect change categories and the amount of emotional change within the categories. The present findings highlight the importance of considering the different ways in which AMs change emotionally from occurrence to later recall.

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.

It is generally accepted that autobiographical memories (AMs) are organised in associative networks. While both thematic and temporal similarity have been examined as connections among AMs, in the present study we focused on both the positive and negative emotional intensity of events as a possible link among AMs. To do so, we investigated whether the output order with which AMs elicited by cue words were reported can be accounted for emotional intensity of adjacent AMs. Data come from 94 older adults (M [Formula: see text] 67.14; SD [Formula: see text] 6.17) who reported 30 AMs in response to neutral cue words. Positive and negative emotional intensity of AMs were assessed on two separate scales (happiness and sadness). The output order was modeled based on a dual mixed-effects autoregressive model, where the strength of the autoregressive effect indicates how much the emotional intensity of an AM can be predicted by the emotional intensity of the previously reported AM. Results show that there were significant autoregressive effects for both the happiness and sadness ratings (accounting for 4% of variance). We also observed cross-over effects, such that the happiness rating of an AM was predicted by the sadness rating of the previously reported AM (and vice versa). Moreover, we found individual differences in the strength of the autoregressive effects. For the sadness ratings, these individual differences tended to be related to the participant's mood state, particularly so during the first output positions. Together, these findings demonstrate that there is a substantive effect of emotional intensity on the output order with which AMs are reported-even when elicited by cue words. Based on the premise that the output order of AMs informs about the organisation of autobiographical memory, our results highlight the role of emotional associations among AMs in old age.

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.

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.
RESUMO
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.

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.

Investigating the recall process of autobiographical memories (AMs) and, particularly, the order in which AMs are recalled has the potential to shed light on the organisation of autobiographical memory. However, research on order effects in the recall of AMs is relatively rare. Moreover, to date, no study addressed the question of where emotion fits into the organisation. The present study aimed to close this gap by examining whether emotional valence serves as one organising principle. Data come from 117 older adults (M = 74.11; SD = 7.06) who reported up to 39 AMs. The use of a multivariate multilevel model with autoregressive effects allows us to analyse the order effect within one person, as well as how the order effect differs between persons. The results replicated a temporal first-order effect that has been shown in previous studies and moreover, demonstrated a temporal second-order effect. Furthermore, our results indicated an emotional first-order effect that was even stronger than the temporal first-order effect and an emotional second-order effect. In addition, both first-order effects differed reliably between persons. Thus, the present study emphasises the need for considering emotion in current theoretical formulations of autobiographical memory and also of considering individual differences in the order of AMs recalled.

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).

We present a Bayesian nonlinear mixed-effects location scale model (NL-MELSM). The NL-MELSM allows for fitting nonlinear functions to the location, or individual means, and the scale, or within-person variance. Specifically, in the context of learning, this model allows the within-person variance to follow a nonlinear trajectory, where it can be determined whether variability reduces during learning. It incorporates a sub-model that can predict nonlinear parameters for both the location and scale. This specification estimates random effects for all nonlinear location and scale parameters that are drawn from a common multivariate distribution. This allows estimation of covariances among the random effects, within and across the location and the scale. These covariances offer new insights into the interplay between individual mean structures and intra-individual variability in nonlinear parameters. We take a fully Bayesian approach, not only for ease of estimation but also for inference because it provides the necessary and consistent information for use in psychological applications, such as model selection and hypothesis testing. To illustrate the model, we use data from 333 individuals, consisting of three age groups, who participated in five learning trials that assessed verbal memory. In an exploratory context, we demonstrate that fitting a nonlinear function to the within-person variance, and allowing for individual variation therein, improves predictive accuracy compared to customary modeling techniques (e.g., assuming constant variance). We conclude by discussing the usefulness, limitations, and future directions of the NL-MELSM.

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.

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.

Typically, subjective memory assessments (be it in form of single items or questionnaires) in old age only weakly correlate with the performance in objective memory tests at cross-section. It thus appears as if individual differences in subjective memory assessments hardly reflect individual differences in memory in old age. A shortcoming of cross-sectional studies, however, is that subjective assessments may rely on different individual standards, which are not taken into account. One solution to this problem has been to investigate subjective and objective memory longitudinally, thereby focusing on individual differences in intraindividual changes. Results from studies using this approach have been mixed, with some studies showing a significantly stronger relation between changes than between levels, and other studies showing no such significant difference. Using data from the Zurich Longitudinal Study on Cognitive Aging (n=236), we find that 5-year changes in subjective assessments of memory capacity and memory changes correlate with objective memory changes of 0.54 and -0.44, respectively. These correlations are significantly stronger than at cross-section. After controlling for age, depressive affect, and subjective health at the first measurement occasion, correlations are slightly attenuated, but the basic findings remain the same.

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.

UNLABELLED: BACKGROUND/STUDY CONTEXT: Previous research has shown an increase of subjective organization of stimuli and of recall performance across learning trials. However, up to date, it has not been examined whether subjective organization and recall performance are positively related also at the level of the individual. To close this gap, parameters of verbal learning were regressed on growth parameters of subjective organization. METHODS: The sample for this investigation involved N = 205 subjects (65 to 80 years old). Participants learned a word list containing 27 unrelated words, presented randomly across five trials. Subjective organization was measured by using the Paired Frequency measure. RESULTS: Overall, there were reliable individual differences with regard to both subjective organization and verbal learning. RESULTS showed that the learning parameters were positively correlated with the initial level and linear slope of subjective organization. Furthermore, growth parameters of subjective organization turned out to be reliable predictors of verbal learning. CONCLUSION: The present study emphasized the role of analyzing individual differences in subjective organization. Implications are discussed, in particular, regarding the interdependency of subjective organization and verbal learning in old age.

The present study examined trajectories of trait positive and trait negative affect as measured by the Positive and Negative Affect Schedule across the lifespan. Increasing levels of measurement invariance of the Positive and Negative Affect Schedule were tested across a wide age range (18-99 years of age; 10 age groups) in a large sample (N = 3,309; 65.82% women; 74.22% with a university entrance diploma; 92.23% with German as their mother tongue). Strong invariance was established so that the latent factor means of positive and negative affect could be meaningfully compared across age groups. Age had a small effect on positive affect, which showed a reversed U-shaped function with a maximum between the ages of 40 and 50. For negative affect, there was a strong cubic age effect. Specifically, negative affect decreased until about the age of 70 and then increased again. We also found a negative covariance between positive and negative affect, which first increased slightly and then decreased across age groups until becoming positive in the oldest age group. In summary, the present study supports previous findings on age trajectories of positive and negative affect but also highlights the importance of testing for measurement invariance.

Introduction: Some events are remembered as more central to a person's identity than others. However, it is not entirely clear what characterizes these autobiographical memories central to one's identity. In this study, we examined the effects of various characteristics on centrality to identity of positive and negative memories. Characteristics such as emotionality, vividness, and how frequently a memory is retrieved and shared with others as well as ruminative and reflective self-foci were studied. Methods: The sample included 356 participants (18-92 years of age). First, participants responded to demographic questions and individual difference questionnaires. Next, they recalled memories in response to 12 emotional cue words. The cue words were balanced for emotional valence (i.e., six positive and six negative) and presented in a random order. After retrieving all memories, participants rated them regarding centrality, using the short seven-item Centrality of Event Scale and other memory characteristics, on a seven-point Likert scale. Multivariate multilevel regression was used for data analyzes, to consider multiple characteristics at the same time and account for data dependency within individual. Results: The results showed that emotionality, vividness, and frequency of memory retrieval contributed to higher centrality of memories, and employing a reflective self-focus resulted in rating memories as more central. In specific cases, these characteristics were associated differently with centrality of positive and negative memories. Discussion: Central memories can be perceived as markers in a person's life story. The findings of this study suggest that these marker events are also highly available in a person's memory system, by being actively emotional, visually rich, and frequently retrieved. Moreover, not only memory characteristics but also individual's features are important to fully understand the autobiographical memory centrality.
RESUMO
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.
RESUMO
The present study examined measurement invariance in the three anger expression subscales of the STAXI (Spielberger, 1988) with respect to gender. In a sample of 576 male and 531 female students, strict measurement invariance was found. For all three anger expression factors, no differences in variances or factor correlations were found. A large negative relation between Anger-Out and Anger-Control emerged. Girls reported significantly lower levels in Anger-Out and Anger-Control than boys. Results suggest that the questionnaire functions the same way across gender. Also, boys and girls exhibited the same range of interindividual differences in anger expression. The negative relation between Anger-Out and Anger-Control suggests that high levels of Anger-Out might be an obstacle in controlling anger. Lower levels of Anger-Out and -Control in girls suggest that girls might need less control because they express anger less outwardly.

UNLABELLED: BACKGROUND/STUDY CONTEXT: Typical intellectual engagement has been postulated as a trait-like construct that can explain interindividual differences in the extent of engaging in cognitively challenging tasks. Although formulated within the framework of cognitive development, the developmental aspects of typical intellectual engagement itself have not been studied yet. METHODS: Three hundred thirty-four participants from the Zurich Longitudinal Study on Cognitive Aging (73 years on average, ranging from 60 to 85) and 468 graduate students (21 years on average, ranging from 18 to 25) were administered a self-rating scale on typical intellectual engagement. Structural equation modeling was used to study differences in factor means, differences in factor variances, and differences in factor covariances between the two groups. RESULTS: Significant mean-level differences between age groups exhibit both decline and increase in old age. An increase in factor variances was shown in the old. Factor correlations were higher in old age compared to young adults. CONCLUSION: Both higher and lower mean levels in the old group imply that typical intellectual engagement is a variable that contributes incremental information compared to well-known measures of basic personality traits. Larger variances in the old imply greater heterogeneity in the old sample, which fits into literature on fan-spread phenomenon. Higher factor covariances in the old imply dedifferentiation of typical intellectual engagement in the old.
