Nostalgia,reflection, brooding: Psychological benefits and autobiographical memory functions

We sought to clarify the psychological profile of experimentally induced nostalgia, compared to two other modes of thinking about one’s past—reflection and brooding—also experimentally induced. We tested both British and Chinese participants. Our main hypothesis was that nostalgia’s profile is more positive in terms of six psychological benefits and seven autobiographical memory functions. The results were consistent with the hypothesis. In regard to psychological benefits, nostalgia (vs. reflection and brooding) increased positive affect, self-esteem, self-continuity, social connectedness, and meaning in life. Furthermore, nostalgia increased optimism relative to brooding (but not reflection). In regard to autobiographical memory functions, nostalgia (vs. reflection and brooding) led to higher boredom reduction, conversation, intimacy maintenance, and death preparation, as well as lower bitterness revival. Nostalgia also elevated teach/inform relative to brooding (but not reflection). The findings were similar for British and Chinese participants.     

Two routes toward optimism: how agentic and communal themes in autobiographical memories guide optimism for the future

Autobiographical memories are particularly adaptive because they function not only to preserve the past, but also to direct our future thoughts and behaviours. Two studies were conducted to examine how communal and agentic themes of positive autobiographical memories differentially predicted the route from autobiographical memories to optimism for the future. Across two studies, results revealed that the degree to which participants focused on communal themes in their autobiographical memories predicted their experience of nostalgia. In turn, the experience of nostalgia increased participants’ levels of self-esteem and in turn, optimism for the future. By contrast, the degree to which participants focused on agentic themes in their memories predicted self-esteem and optimism, operating outside the experience of nostalgia. These effects remained even after controlling for self-focused attention. Together, these studies provide greater understanding of the interrelations among autobiographical memory, self-concept, and time, and demonstrate how agency and communion operate to influence perceptions of one’s future when thinking about the past.     

Not all semantics: Similarities and differences in reminiscing function and content between Indigenous and non-Indigenous Australians

This study explored why and how Indigenous and non-Indigenous Australians remember the past. Indigenous Australians traditionally share a strong oral tradition in which customs, personal and cultural histories, and other narratives are passed across groups and between generations by word of mouth. Drawing on this tradition, in which inherent value is placed on sharing knowledge and maintaining connectedness with others, we hypothesised that Indigenous Australians would be more likely than non-Indigenous Australians to report reminiscing to fulfil social functions (but not self or directive functions). Furthermore, we hypothesised that Indigenous Australians would recall personal past experiences more elaborately than would non-Indigenous Australians. In Study 1, 33 Indigenous Australians and 76 non-Indigenous Australians completed Webster's Reminiscence Functions Scale. As predicted, Indigenous participants reported higher scores on subscales related to social functions than did non-Indigenous Australians: particularly “Teach/Inform” and “Intimacy Maintenance”. They also scored higher on the “Identity” subscale. In Study 2, 15 Indigenous and 14 non-Indigenous Australians shared three memories from the distant and recent past. While Indigenous and non-Indigenous narratives did not differ in either emotion or elaboration, Indigenous Australians provided more memory context and detail by including a greater proportion of semantic memory content. Taken together, these findings suggest differences in both why and how Australians remember.     

Reminiscence Functions Across Adulthood: A Replication and Extension

Reminiscence, a naturally occurring process of recalling personally experienced events from our past, has been investigated primarily from a clinical, gerontological perspective. A total of 268 participants (100 male, 168 female) ranging in age from 17 to 88 years (M age = 40.02, SD = 20.32) completed the Reminiscence Functions Scale (RFS), the Memorial University of Newfoundland Scale of Happiness (MUNSH), and a single-item question assessing the perceived importance of shared family memories. Results indicated neither age nor gender differences on the total RFS score, indicating that men and women of all ages reminisce equally frequently. However, there were gender and age differences on specific dimensions of reminiscence. Specifically, women scored higher on the RFS factor of Identity (Idn) and lower on Bitterness Revival (BiR). Younger adults tended to score higher on the RFS factors of Boredom Reduction (BoR), BiR, Problem-Solving (PS), and Idn compared to older adults. In contrast, older adults tended to score higher on the RFS factors of Teach/Inform (T/I) and Death Preparation (DP). BoR, BiR, and PS correlated negatively with happiness, whereas Conversation (C) and T/I correlated positively with happiness. Finally, T/I, Intimacy Maintenance (IM), Idn, and C all correlated positively with the measure of the perceived importance of shared family memories. The results replicate earlier work with the RFS and suggest that examining reminiscence from a contextual, lifespan perspective is an important research area.     

Role of anxiety and brooding in specificity of autobiographical recall

Overgeneral schemas and lack of autobiographical memory (AM) specificity about our past experiences can predict mood disturbance. Rumination, functional avoidance and executive processes are the main explanatory variables of such overgenerality. However, in non‐clinical samples, rumination predicts overgenerality most consistently after the induction of dysphoric mood. Anxiety also activates rumination. Furthermore, anxiety predicts memory performance and has effects on mood which are independent of the effects of rumination. So, what might be the role of anxiety in autobiographical memory performance? A sample of 210 voluntary participants reported measures of autobiographical memory, anxiety, rumination (brooding and reflection), functional avoidance and executive functions (semantic and phonetic verbal fluency task). Autobiographical performance (specificity) was negatively associated with brooding and age and positively with phonetic verbal fluency but not with functional avoidance and anxiety. However, anxiety and brooding were positively correlated even after controlling for depression scores. Moreover, using structural equation modeling, anxiety showed a significant indirect effect on autobiographical specificity through brooding rumination. These results suggest a possible association of anxiety with autobiographical recall through brooding rumination.     

沉思和分心对负情绪和自传体记忆的影响

探讨在诱发了抑郁、焦虑、悲伤等负性情绪后,沉思和分心对正常成人的情绪主观报告、生理变化和自传体记忆的作用。64名被试被随机分为两组,用故事和电影短片分别诱发了负性和中性（控制组）两种情绪状态。然后进行随机分组,分别进行分心和沉思的反应任务。测量四组被试的情绪主观报告、生理变化以及多种形式和性质的自传体记忆。结果表明：（1）沉思和分心对这些负情绪的调节作用不显著;（2）沉思引起更多的负性记忆,正性复合指数更小,自传体记忆的具体性更弱。结论：沉思导致更多负性记忆,维持了概括性记忆,更有可能加重已经激活的负情绪     

Associations between components of rumination and autobiographical memory specificity as measured by a Minimal Instructions Autobiographical Memory Test

Clinical studies have shown that rumination functions as a mediator between overgeneral memory—the tendency to retrieve autobiographical memories in a non-specific format—and depression. Recently, rumination has been dismantled into two distinct subcomponents: reflection, which is more adaptive, and brooding, which is more maladaptive. In the present study we examined the differential relationships of these two rumination subcomponents with autobiographical memory specificity and their mediational role for the relationship between reduced memory specificity and depression in a non-clinical sample. In addition, we investigated the usefulness of a “minimal instructions” version of the Autobiographical Memory Test (AMT) to measure memory specificity in non-clinical populations. Results indicated that the use of minimal instructions can increase the AMT's sensitivity to detect reduced autobiographical memory specificity in non-clinical individuals. Further it was found that brooding, and not reflection, is significantly associated with reduced autobiographical memory specificity and functions as a mediator between reduced memory specificity and depression.     

Rumination and overgeneral autobiographical memory

Two studies investigated the effects of rumination on the retrieval of autobiographical memories in high-depressed and low-depressed individuals. Experiment 1 administered either a rumination or distraction task prior to a cued autobiographical memory task. High-depressed participants recalled more overgeneral memories following rumination relative to distraction, whereas experimental inductions did not influence low-depressed participants. Experiment 2 administered either a positive or negative rumination task prior to a cued autobiographical memory task. Negatively valenced rumination led high-depressed participants to recall more overgeneral memories than positively valenced rumination; this effect was not observed in low-depressed participants. These findings accord with the proposal that rumination is a mediating mechanism in the retrieval of overgeneral memories, and extends this proposal by indicating that negatively valenced ruminative content is particularly instrumental in inducing overgeneral retrieval.     

Ruminative self-focus and autobiographical memory

Many studies have shown a positive relationship between elevated dispositional self-focus and emotional disorder. Trapnell and Campbell (1999) proposed that this relationship was only true for ruminative forms of self-focus, reflective self-focus being associated with psychological health. The present study aimed: (1) to examine the replicability of Trapnell and Campbell's (1999) questionnaire-based differentiation of reflective and ruminative dispositional self-focus; (2) to see whether reflection and rumination could also be differentiated using measures of autobiographical memory; (3) to see whether such memory measures could elucidate mechanisms underlying different forms of dispositional self-focus. 130 volunteers retrieved autobiographical memories to neutral cue words and completed questionnaires. Questionnaires differentiated reflection and rumination: reflection correlated with openness to experience, whereas rumination correlated with neuroticism, replicating previous findings that it is specifically ruminative self-focus that is maladaptive. Memory measures also differentiated reflection and rumination: reflection was unrelated to the affective qualities of memories, whereas rumination correlated with measures of the happiness, unhappiness and at-oneness of memories. Dispositional ruminative self-focus, like neuroticism, was specifically related to increased accessibility of memories of events where individuals felt “not at all at-one with things”. This style of memory access could underpin dispositional ruminative self-focus, which is closely linked to neuroticism.     

Nostalgia for Communist Times and Autobiographical Memory: Negative Present or Positive Past?

Twenty‐five years after the fall of communism in Poland, a considerable number of citizens manifest nostalgia for the communist times. In this article, we approach this phenomenon within the framework of autobiographical memory and decide between two sets of hypotheses, one predicting that postcommunist nostalgia is experienced mostly by people who are dissatisfied with the present time (transformation “losers”) and the other predicting that it is the memory of the happy and most recollected past, and memories of particular decades of communism, that mostly trigger nostalgia. The study, carried out on a representative sample of Poles who remembered communism, provided stronger confirmation of the “negative present” hypothesis, but the positive past is also shown to matter. The decade of communism whose memory turned out to predict nostalgia the best was the 1980s and not, as predicted, the 1970s.     

Characterisation of music-evoked autobiographical memories

Despite music's prominence in Western society and its importance to individuals in their daily lives, very little is known about the memories and emotions that are often evoked when hearing a piece of music from one's past. We examined the content of music-evoked autobiographical memories (MEAMs) using a novel approach for selecting stimuli from a large corpus of popular music, in both laboratory and online settings. A set of questionnaires probed the cognitive and affective properties of the evoked memories. On average, 30% of the song presentations evoked autobiographical memories, and the majority of songs also evoked various emotions, primarily positive, that were often felt strongly. The third most common emotion was nostalgia. Analyses of written memory reports found both general and specific levels of autobiographical knowledge to be represented, and several social and situational contexts for memory formation were common across many memories. The findings indicate that excerpts of popular music serve as potent stimuli for studying the structure of autobiographical memories.     

Investigating whether maternal memory specificity is indirectly associated with child memory specificity through maternal reminiscing

Maternal reminiscing and remembering has a profound influence on the development of children’s autobiographical remembering skills. The current study investigated the relationships between maternal memory specificity, maternal reminiscing and child memory specificity. Participants consisted of 40 mother–child dyads. Children’s age ranged between 3.5 and 6 years. Mothers and children participated in individual assessments of autobiographical memory specificity. Dyads participated in a joint reminiscing task about three past emotional (happy, sad, stressful) events. A positive moderate association was found between maternal autobiographical memory specificity and child autobiographical memory specificity. Maternal autobiographical memory specificity was significantly correlated with mothers’ focus on the task, involvement and reciprocity, resolution of negative feelings, and structuring of narratives in the mother–child reminiscing task. Moderate positive associations were found between maternal focus and structuring and child memory specificity. There was no evidence to suggest maternal elaborative reminiscing style was significantly positively correlated with mother or child memory specificity. Finally, there was support for an indirect pathway between maternal memory specificity and child memory specificity through quality of support and guidance provided by the mother in maternal reminiscing. Theoretical and clinical implications are considered.     

Influence of outcome valence in the subjective experience of episodic past, future, and counterfactual thinking

Recent findings suggest that our capacity to imagine the future depends on our capacity to remember the past. However, the extent to which episodic memory is involved in our capacity to think about what could have happened in our past, yet did not occur (i.e., episodic counterfactual thinking), remains largely unexplored. The current experiments investigate the phenomenological characteristics and the influence of outcome valence on the experience of past, future and counterfactual thoughts. Participants were asked to mentally simulate past, future, and counterfactual events with positive or negative outcomes. Features of their subjective experiences during each type of simulation were measured using questionnaires and autobiographical interviews. The results suggest that clarity and vividness were higher for past than future and counterfactual simulations. Additionally, emotional intensity was lower for counterfactual simulations than past and future simulations. Finally, outcome valence influenced participants' judgment of probability for future and counterfactual simulations.     

Autobiographical memory functions and posttraumatic stress symptoms across adulthood

Previous research has documented robust individual differences in the functions served by autobiographical memories, and shown that different autobiographical memory functions are related to both positive and negative indicators of psychological well-being, and that their frequency varies with age. In this study, we examined the unique relationship between autobiographical memory functions and posttraumatic stress symptoms (PTSS) and whether such relationships varied with age across adulthood. A representative sample of 1040 adult Danes (20–70 years old) reported the frequency with which they recall autobiographical memories for different purposes as well as their level of posttraumatic stress disorder (PTSD) symptoms. Higher reflective and ruminative functions, as well as lower social function, predicted higher levels of PTSS. There were no moderating effects of age. The results suggest that although the frequency of various autobiographical functions varies throughout the adult years, their association with PTSS is similar across adulthood.     

The functions of autobiographical memory: An integrative approach

Recent research in cognitive psychology has emphasised the uses, or functions, of autobiographical memory. Theoretical and empirical approaches have focused on a three-function model: autobiographical memory serves self, directive, and social functions. In the reminiscence literature other taxonomies and additional functions have been postulated. We examined the relationships between functions proposed by these literatures, in order to broaden conceptualisations and make links between research traditions. In Study 1 we combined two measures of individual differences in the uses of autobiographical memory. Our results suggested four classes of memory functions, which we labelled Reflective, Generative, Ruminative, and Social. In Study 2 we tested relationships between our four functions and broader individual differences, and found conceptually consistent relationships. In Study 3 we found that memories cued by Generative and Social functions were more emotionally positive than were memories cued by Reflective and Ruminative functions. In Study 4 we found that reported use of Generative functions increased across the lifespan, while reported use of the other three functions decreased. Overall our findings suggest a broader view of autobiographical memory functions that links them to ways in which people make meaning of their selves, their environment, and their social world more generally.     

Going global: Functions of autobiographical remembering world tour

This special issue showcases research from around the world that takes a functional approach to autobiographical remembering. In doing so, it inspires researchers to reach out to new populations. This commentary begins with a brief history of the functional approach. Person–environment interactions, in this case how individuals use memory in their current cultural context, are at the core of that approach. Based on current theoretical thinking in this area, I review the papers in this issue with the aim of exploring: (1) where culture and function might fit in current conceptualisations of autobiographical memory, (2) the relation of culture to socio-structural variables such as gender and life phase in shaping the functions of memory and (3) differences in cultural tendencies to use autobiographical memory as a resource to fulfil universal human needs.     

A longitudinal study of processes predicting the specificity of autobiographical memory in the adolescent offspring of depressed parents

Deficits in specific autobiographical memory retrieval are closely associated with depression. The ability to retrieve specific autobiographical memories develops throughout childhood and adolescence and is associated with adolescent depression within and across time. Studying young samples before they first experience depression provides an approach for testing processes that underlie reduced autobiographical memory specificity. This study is the first to examine the longitudinal association of rumination and executive function with autobiographical memory specificity in a sample of adolescents at elevated risk for future depression. A total of 259 adolescents (aged between 10 and 18 years) completed the Autobiographical Memory Test at baseline and 1-year follow-up. Measures of rumination, executive function, and depressive symptoms were obtained at baseline. The interaction between rumination and executive function predicted autobiographical memory specificity over time. Whereas rumination in the context of low executive function predicted reduced specificity, this was not the case in the context of high executive function. The interaction between rumination and executive function was independent of the effects of age, gender, IQ, baseline levels of memory specificity, and depressive symptoms.     

The effect of the order in which episodic autobiographical memories versus autobiographical knowledge are shared on feelings of closeness

Autobiographical memories (AMs) can be used to create and maintain closeness with others [Alea, N., &; Bluck, S. (2003). Why are you telling me that? A conceptual model of the social function of autobiographical memory. Memory, 11(2), 165–178]. However, the differential effects of memory specificity are not well established. Two studies with 148 participants tested whether the order in which autobiographical knowledge (AK) and specific episodic AM (EAM) are shared affects feelings of closeness. Participants read two memories hypothetically shared by each of four strangers. The strangers first shared either AK or an EAM, and then shared either AK or an EAM. Participants were randomly assigned to read either positive or negative AMs from the strangers. Findings suggest that people feel closer to those who share positive AMs in the same way they construct memories: starting with general and moving to specific.     

Overgeneral past and future thinking in dysphoria: the role of emotional cues and cueing methodology

Overgeneral memory, where individuals exhibit difficulties in retrieving specific episodes from autobiographical memory, has been consistently linked with emotional disorders. However, the majority of this literature has relied upon a single methodology, in which participants respond to emotional cue words with explicit instructions to retrieve/simulate specific events. Through the use of sentence completion tasks the current studies explored whether overgenerality represents a habitual pattern of thinking that extends to how individuals naturally consider their personal past and future life story. In both studies, when compared with controls, dysphoric individuals evidenced overgeneral thinking style with respect to their personal past. However, overgeneral future thinking was only evident when the sentence stems included emotional words. These findings highlight the importance of investigating the overgenerality phenomenon using a variety of cueing techniques and results are discussed with reference to the previous literature exploring overgenerality and cognitive models of depression.
