THE REMINISCENCE EFFECT IN AUTOBIOGRAPHICAL MEMORY AND TESTS OF ITS PROMINENT ACCOUNTS by Justin T. Coleman A DISSERTATION Presented to the Faculty of The Graduate College at the University of Nebraska In Partial Fulfillment of Requirements For the Degree of Doctor of Philosophy Major: Psychology Under the Supervision of Professor Robert F. Belli Lincoln, Nebraska November, 2012 THE REMINISCENCE EFFECT IN AUTOBIOGRAPHICAL MEMORY AND TESTS OF ITS PROMINENT ACCOUNTS Justin T. Coleman, Ph.D. University of Nebraska, 2012 Adviser: Robert F. Belli The reminiscence effect, in which people aged 40 and over remember more autobiographical memories from between ages 10 to 30 than from adjacent periods, producing a “bump” in lifespan distributions, is a highly robust effect. When it was discovered to occur for highly positive emotional memories, but not negative ones, the cultural life script account of reminiscence was proposed. The cultural life script account asserts that individuals possess scripts for important events in the normative life that structure autobiographical recall. The reminiscence effect is explained by the fact that in life scripts, positive events have highly prescribed timings and cluster between ages 10 and 30, while negative events, which do not have prescribed timings, are more evenly distributed across the lifespan. The life story account outlines additional properties of bump memories. The life story account attributes reminiscence to the differential recall of life story events, i.e., events that provide coherence to one’s life story. Four studies are reported testing these accounts. Chapter 2 reports a test of the life script with African Americans. Research suggests that life scripts are highly stable, varying little across cultures. The findings indicate that, overall, the properties of the life script were replicated. However, minor cross-cultural differences similar to those observed in prior research were exacerbated with a minority sample. In Chapter 3, the effect of minority status on the recall of emotionally negative memories is examined. Contrary to expectations, the findings failed to contradict the predictions of either account of reminiscence. In Chapter 4, the typicality effect is tested with life scripts in an attempt to present an additional class of evidence for their existence. Finally, in Chapter 5, the life story account is tested. The findings support the life story account by showing that the bump occurs for life story, but not non-life story, events. These studies add to our understanding of the cultural life script and life story accounts and the reminiscence effect in autobiographical memory. iv Contents CHAPTER 1 ........................................................................................................................1 INTRODUCTION .......................................................................................................... 1 REVIEW OF RESEARCH ON TEMPORAL DISTRIBUTION OF AM ..................... 6 1.

  • Life Happens When You Are Young: Reminiscence Bump in Cultural Life Scripts Regardless Of
    1 RUNNING HEAD: REMINISCENCE BUMP IN CULTURAL LIFE SCRIPTS Life happens when you are young: Reminiscence bump in cultural life scripts regardless of number of events Word count Introduction and Discussion: 2000 Word count Main Text: 2951 Annette Bohn1, Jonathan Koppel2 and Celia B.

[email protected] 2 Abstract Cultural life scripts are representations of a prototypical life course within a culture, consisting of a shared understanding of culturally important transitional events and their timing. Cultural life scripts contain a “bump” for events in adolescence and early adulthood, mirroring the reminiscence bump in autobiographical memory. However, the bump in the cultural life script might be due to the typical methodology used, namely generating only the seven most important events in a prototypical life, thus prioritizing early events. Here, we tested whether expanding the number of events would level the bump in the cultural life script. Four groups of 100 participants each generated a cultural life script with four, seven, 15 or 25 events. Across groups, there was a clear bump in adolescence and early adulthood, showing that the bump in cultural life scripts is highly robust and not an artefact of methodology.

  • The Breadth and Mnemonic Consequences of the Youth Bias
    The breadth and mnemonic consequences of the youth bias Jonathan Koppel and Dorthe Berntsen Department of Psychology and Behavioural Sciences, Center on Autobiographical Memory Research, Aarhus University, Aarhus, Denmark Abstract We have recently demonstrated the existence of the youth bias, referring to a tendency to favour adolescence and early adulthood over other lifetime periods when making inferences about the timing of important public events across the lifespan of a typical individual within one’s culture. The youth bias integrates two discrete lines of research, that is, the literature on the privileged status of adolescence and early adulthood in human memory and cognition, and the literature on cognitive biases. Here we first examined whether the youth bias holds for specific categories of public events (i.e., deaths of public figures, United States presidential elections, and sporting events). We then investigated the possible role of the youth bias in structuring recall for public events, by probing, within subjects, for the relation between: (1) these expectations of the timing, in a typical person’s life, of the most important exemplar from each public event category, and (2) the age at which the cited event occurred on a recall question asking participants to cite the most important exemplar, in their own lifetime, from each category. We found a youth bias for each category. Additionally, responses to the youth bias question were correlated with the age at which the recalled event occurred, but only where particularly salient historical events did not play a central role in driving recall (i.e., for sporting events). We conclude that the youth bias holds across different types of public events and provides a default structure for organizing recall of public events.

  • Changes in Reliving and Vividness Over the Life Span Do Not Explain the Reminiscence Bump

  • Effects of Voluntary Immigration on the Distribution of Autobiographical Memory Over the Lifespan
    APPLIED COGNITIVE PSYCHOLOGY Appl. Cognit. Psychol. 15: S75±S88 2001) DOI: 10.1002/acp.835 Effects of Voluntary Immigration on the Distribution of Autobiographical Memory over the Lifespan ROBERT W. SCHRAUF1* and DAVID C. RUBIN2 1Buehler Center on Aging, Northwestern University Medical School, USA 2Department of Psychology:Experimental, Duke University, USA SUMMARY Immigration may be considered a `traumatic' event with acute phases followed by long latency effects. Ten older, Hispanic adults who immigrated to the USA at ages 20±22, 24±28, and 34±35 narrated their `life-stories' on two occasions, once in English and once in Spanish. Instead of the usual reminiscence bump they showed an increase in autobiographical recalls corresponding speci®cally to their ages at immigration. Each of the narrated life stories was independently coded for amount of detail, emotional valence, status as transitional event, and backward/forward search strategy. Memories for the time of immigration did not differ from other memories on any of these ratings. Increased recall for the period of immigration may be due to the encoding of novel events and the `effort after meaning' required to integrate these events followed by a relatively stable period settlement) marked by release from proactive interference and spaced rehearsal. Copyright # 2001 John Wiley & Sons, Ltd. Popular and psychological understandings describe trauma as a violent shock to the mental organism, which overtaxes normal abilities to assimilate and integrate the experience. Sequelae include subsequent attempts to accomplish such hermeneutic integration. The experience of immigration would be traumatic only in an analogous sense, and Grinberg and Grinberg 1989) in Psychoanalytic Perspectives on Immigration and Exile make precisely this case.

  • Why Does the Adolescence Bump Differ from the Emergent Adulthood Bump in Autobiographical Memories? Journal of Applied Research on Memory and Cognition, 4, 84-86

Adorno Platz 6, D-60323 Frankfurt a. M., Germany. Phone: +49 69 798 35405. Abstract Koppel and Berntsen (2015) discuss the differing temporal locations of the reminiscence bump arising from different instructions. We suggest that identity, life script, life story and novelty need not be discussed as alternative explanations. Rather, they may be integrated into an explanation which also includes a motivational dimension. We sustain that an exclusive use of the life script for retrieval would predict a homogenous and stable set of memories across individuals of the same subculture. An exclusive use of self-concept and explicit motives would predict a highly heterogeneous and volatile set of memories. An exclusive use of the life story schema would predict an only somewhat heterogeneous set of memories slowly changing as life is being lived. This, we suggest, may be closest to what is to be expected from longitudinal findings.

Participants over the age of 40 were presented with top-grossing films and songs, and were asked to select the five that were most personally significant. Study 1 produced reminiscence bumps for personally significant songs, when measured by both participants’ age at release (AaR) and age when songs were reported as most important (AaI). This effect was not shown for films. In Study 2, participants again selected their personally significant songs but also rated all songs for whether they were known, remembered (e.g., associated with an episodic memory), or not known.

  • A Review of Autobiographical Memory Studies on Patients with Schizophrenia Spectrum Disorders Yujia Zhang1†, Sara K
    Zhang et al. BMC Psychiatry (2019) 19:361 https://doi.org/10.1186/s12888-019-2346-6 RESEARCH ARTICLE Open Access A review of autobiographical memory studies on patients with schizophrenia spectrum disorders Yujia Zhang1†, Sara K. Kuhn2†, Laura Jobson3† and Shamsul Haque1*† Abstract Background: Patients suffering from schizophrenia spectrum disorders demonstrate various cognitive deficiencies, the most pertinent one being impairment in autobiographical memory. This paper reviews quantitative research investigating deficits in the content, and characteristics, of autobiographical memories in individuals with schizophrenia. It also examines if the method used to activate autobiographical memories influenced the results and which theoretical accounts were proposed to explain the defective recall of autobiographical memories in patients with schizophrenia. Methods: PsycINFO, Web of Science, and PubMed databases were searched for articles published between January 1998 and December 2018. Fifty-seven studies met the inclusion criteria. All studies implemented the generative retrieval strategy by inducing memories through cue words or pictures, the life-stage method, or open-ended retrieval method. The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Statement guidelines were followed for this review. Results: Most studies reported that patients with schizophrenia retrieve less specific autobiographical memories when compared to a healthy control group, while only three studies indicated that both groups performed similarly on memory specificity. Patients with schizophrenia also exhibited earlier reminiscence bumps than those for healthy controls. The relationship between comorbid depression and autobiographical memory specificity appeared to be independent because patients’ memory specificity improved through intervention, but their level of depression remained unchanged. The U-shaped retrieval pattern for memory specificity was not consistent.

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
