EXAMINING THE INFLUENCE OF TIME AND REPETITION ON RECENT AND REMOTE AUTOBIOGRAPHICAL MEMORY RETRIEVAL USING fMRI

Campbell, Jennifer Lynn January 2009 (has links)
Repetition and the passage of time influence the consolidation of long-term episodic memories. The experiments presented here have explored the influence of repetition on recent and remote autobiographical memories both behaviorally with regard to qualitative and quantitative measures of content, and neuroanatomically, focusing on changes within the hippocampus and adjacent structures. The first experiment tested the prediction made by MTT that hippocampal memory traces expand and strengthen as a function of repeated memory retrievals. An fMRI paradigm was used to compare the effect of memory retrieval versus the mere passage of time on hippocampal activation. Participants retrieved remote autobiographical memories that had been previously retrieved either one month earlier, two days earlier, or multiple times during the preceding month. Behavioral analyses revealed that the number and consistency of memory details retrieved increased with multiple retrievals but not with the passage of time. Hippocampal activation did not change as a function of either multiple retrievals or the passage of time. The second behavioral investigation was a follow-up to the first experiment, examining the retrieval of those same memories one year later in order to determine whether the level of detail remained stable or whether the memories returned to their original state. Participants reported even more details than they had recalled at least one year earlier, including new details. This finding was consistent across both multiple and single retrieval conditions. These findings together with those of the first study suggest that both repetition and the passage of time are important factors that may result in an increase in recall. The third and final experiment explored the behavioral and neural influences of repeated reactivation of both recent and remote autobiographical memories. Participants were interviewed a total of five times throughout one month and retrieved 20 significant life event memories, from either within the past several months or more than five years ago. Additionally, two fMRI scan sessions were collected, which enabled a direct comparison of the same 20 memories before and after a series of repetitions. Activation increased with repetition in several brain regions including bilateral posterior cingulate and precuneus. Behaviorally, repetition resulted in increased accessibility as suggested by decreased reaction times between the initial and final retrieval sessions, and a general maintenance of the level of recall resulted with repetition.

Towards an understanding of tradition in Cree women's narratives, Waskaganish, James Bay

Garrard, Margaret January 2004 (has links)
This thesis examines the ways in which Cree women of Waskaganish, James Bay use and understand the concept of tradition in narratives about their lives and changes in their community. The fieldnotes of anthropologist Regina Flannery, completed in the 1930's, serve to orient this research, and provide a starting point for discussion. / As northern communities continue to adapt in the face of social and economic changes, cultural categories such as tradition have concurrently undergone reevaluation. It is argued here that the meanings of tradition have become more complex as Cree women adjust to their changing environment. / It is demonstrated that tradition is used as a narrative tool in descriptions of the past, and a means by which women can discuss change and the future of their community. In addition, tradition currently occupies a significant symbolic space in women's individual cultural identities, and is incorporated in daily life in various ways. Furthermore, tradition has also become an important component of Cree political discourse. Finally, it is apparent that tradition remains a contested category among women themselves, and dissent exists as to the future transmission of traditional practices, language and values. / From this analysis, tradition emerges as a nuanced term that has a number of conceptual modalities. It is suggested that a more comprehensive grasp of complex concepts such as tradition is made possible through the prioritization of personal narratives, and the exploration of the ways in which individuals utilize, comprehend and expand on cultural categories.

Mining experience : the ageing self, narrative, and social memory in Dodworth, England

Degnen, Cathrine January 2003 (has links)
In response to the anthropological literature on old age and ageing that remains largely isolated from more contemporary anthropological theory, this thesis re-focuses anthropological attention on the experiences of ageing. Towards this end, I examine the way macro- (history, politics, economics) and micro-level processes (social relations, intergenerational relations, local contexts, individual histories) intersect to frame the cultural construction of old age, personal experiences of "being old", and the self. A central point of intersection between these processes comes from the recent history of social transformation in my fieldsite, Dodworth, a former coal-mining village. Since the late 1980s, this is an area that has been grappling with the rupturing effects of the closure of the coal-mining industry. Attending to these conditions and how they inform the everyday reality and the experiences of ageing and of the self are critical concerns in this thesis. My approach to the ageing self is one that privileges narrativity and temporality as key constitutive elements and which considers the potentially different position of older people in relation to time and to the self. Growing older is a complicated mixture of bodily and social change, and negotiating these shifts has crucial implications for one's sense of self and subjectivity. While "old age" is a category which is readily used in daily discourse and living, what old age is and who is old nevertheless resists anchoring. What old age, being old and ageing meant to my research participants are key questions in order to understand the experience of growing older in Dodworth. Throughout the thesis, I focus on the dialectics of interpersonal interactions in order to speak meaningfully about how the experience of old age is organised and constructed. Emerging in tandem with these issues is another major topic of this thesis: social memory. Talk in Dodworth about places, absences, and relations continually brought the past and present together and was involved in how a sense of self is created. What emerged was a three-dimensionality of memory, an individual and collective way of placing oneself and others in relation to spatial aspects of the villagescape.

Priklausomų nuo narkotinių medžiagų vyrų autobiografinės atminties ypatumai reabilitacijos metu / Autobiographical memory features of drug addicted men during their reabilitation process

Selmistraitytė, Lina 26 June 2014 (has links)
Šiuo tyrimu siekta atsakyti į klausimą, ar priklausomų nuo narkotinių medžiagų asmenų autobiografiniai prisiminimai reabilitacijos metu skiriasi nuo nepriklausomų savo konkretumu, dominuojančiais kontekstais bei subjektyviu vertinimu. Tikslui pasiekti buvo atliekamas pusiau struktūruotas interviu individualiai su 16 Vilniaus priklausomybės ligų centro ilgalaikės reabilitacijos skyriuje esančių nuo priklausomybės narkotikais besigydančių asmenų bei 15 sveikų panašaus amžiaus vyrų. Priklausomų asmenų amžiaus vidurkis buvo 26,56 metai (SD=2,73), o kontrolinės grupės amžiaus vidurkis – 24,06 (SD=1,75). Iš viso buvo surinkti 186 prisiminimai, kurie kiekvienas buvo nepriklausomų vertintojų užkoduotas pagal parengtą kodavimo schemą. Kodavimo schema buvo sudaryta iš keturių kontekstų kategorijų, joje taip pat buvo prašoma įvertinti prisiminimų konkretumą/ neapibrėžtumą, taisyklių laikymąsi. Klinikinės ir kontrolinės grupės buvo lyginamos pagal polinkį atgaminti neapibrėžtus bei konkrečius prisiminimus, polinkį juos vertinti neigiamai arba teigiamai, dominuojančius kontekstus. Abiejų grupių papasakoti ankstyvieji prisiminimai buvo lyginami pagal jų subjektyvų vertinimą bei išsiskiriančius kontekstus. Neapibrėžtumo/ konkretumo savybė buvo lyginama tarp grupių pateiktų prisiminimų į emocinius raktinius žodžius. Iš šių prisiminimų taipogi buvo siekiama išskirti dominuojančius kontekstus, palyginti jų subjektyvų vertinimą bei patikrinti kitas jų ypatybes. Nustatyta, jog priklausomų asmenų... [toliau žr. visą tekstą] / This study was conducted to answer the question weather the specificity, dominating contexts or subjective valency of autobiographical memories of drug addicted men during rehabilitation process differ from the ones of non addicted individuals. For this purpose the half structured interview was made with 16 drug addicted patients in Vilnius Center for Addictive Disorders in long-term rehabilitation department and with 15 non addicted men of the same age. Averagely drug addicted men were 26.56 years old (SD=2.73). The mean age of control group was 24.06 (SD=1,75) years. 186 memories were collected. Independent experts coded these memories using the coding scheme. The coding scheme was made of 4 contexts groups, memories’ specificity/ over-generality assessment, assessment weather they are according to instructions or not. The clinical and the control groups were compared according to the tendencies to remember more specific memories; according to more positive or negative memory assessment tendencies and the tendencies to remember the particular things, themes. The early memories of both groups were compared according to subjective emotional assessment and the contexts dominating. Also the specificity/ over-generality feature of the memories recalled to the key words was compared between the two groups. Also it was important to distinguish dominant contexts, compared to their subjective assessment, and verify the other of their characteristics. It was found that drug addicted... [to full text]

The Implications of autobiographical memory style for the deficits associated with borderline personality disorder

Reid, Tamar January 2008 (has links)
Research Doctorate - Doctor of Philosophy (Clinical Psychology) / Overgeneral autobiographical memory is thought to be a clinically meaningful phenomenon which is related to affect regulation, problem solving ability, and treatment outcome in clinical populations (see J. M. G. Williams et al., 2007, for review). Individuals with Borderline Personality Disorder (BPD) are thought to be particularly prone to developing an overgeneral style of memory due to their temperamental difficulties in controlling affect (J. M. G. Williams, 1996). However, research in this population has so far yielded inconsistent findings. In a series of three studies, this thesis addresses the question whether overgeneral memory is associated with BPD, as well as exploring the relationship between memory specificity, affect regulation, problem solving ability, and response to treatment in this population. Findings indicate that individuals with BPD display reduced autobiographical specificity relative to controls, however, this appears to be a reflection of differences in cognitive ability as IQ and education mediated the association between specificity and diagnosis. Reduced specificity was not associated with Borderline traits in a non-clinical sample. Results failed to confirm the hypothesis that autobiographical memory specificity would be related to affect regulation in individuals with BPD, although there was some indication that memory specificity is associated with reduced rates of deliberate self-harm. Specificity was related to problem solving performance in individuals with BPD, although this relationship did not extend to self-reported problem solving ability. Memory specificity also appeared to change significantly over the course of treatment in a year-long Dialectical Behavior Therapy program, however, there was little indication that change in memory specificity was associated with the observed improvement in symptomatology, affect regulation or problem solving ability. Lastly, an experimental study with university students found no relationship between memory specificity and affect dysregulation, although low specific students reported greater reductions in positive affect following a negative event than individuals with a specific style of autobiographical recall. The assimilation model is considered as a framework for conceptualising these results.

The Role Of Code-Switching In Emotional Expression And Autobiographical Memory Recall: Implications For Bilingual Counseling

Pang, Lan-Sze 01 January 2009 (has links)
The purpose of the study was to gain an in-depth understanding of the emotional expression in the narration of autobiographical stories of Chinese international students in their respective languages (i.e., Mandarin and English). It addressed the methodological limitations of previous research on bilinguals' emotional expression and autobiographical memory recall. A phenomenological approach with Conversation Analysis was used to examine the bilingual lived experience of 8 graduate students from mainland China through an individual 60-minute bilingual semi-structured interview. The participants were asked to share stories before and after their arrival in the United States, as well as to self-reflect on their use of their respective languages during the interview and in their daily life. Several strategies were employed to establish four areas of trustworthiness in the qualitative data. Four major themes and related sub-themes emerged from the bilingual interview data including Mandarin as the Base Language, Affective Repertories of Mandarin (Use of Chinese Idioms and Proverbs, Use of Analogy, and Use of Repetition), Code-Switching as an Additional Communication Resource (Mixed Attitudes Towards Code-Switching, Non-Affective Functions of Code-Switching, and Affective Functions of Code-Switching), and Emotional Representation of the Bilingual Self (Open versus Reserved and Formal versus Casual). Finally, research limitations, future directions, and implications for bilingual counseling are discussed.

Relações entre estilo cognitivo verbal-visual, recordação e expressão narrativa de eventos autobiográficas

Alencastro, Luciano da Silva January 2009 (has links)
A presente dissertação investigou a relação entre estilo cognitivo verbal-visual, recordação e expressão narrativa de eventos autobiográficos. Cento e quatro estudantes universitários realizaram as seguintes tarefas: 1) Relato de Evento Autobiográfico; 2) Questionário de Memória Autobiográfica (QMA); 3) Questionário Verbalizador-visualizador (QVV); e 4) versão reduzida do Bett´s Questionnarie Upon Mental Imagery. A análise fatorial do Estudo I distinguiu dois níveis da recordação de eventos pessoais: 1) processos cognitivos pouco dependentes de recursos reflexivos e concomitantes ao ato de recordar, como a vivacidade de imagens; e 2) processos reflexivos, nos quais se destacam as avaliações e juízos acerca da importância do evento. O Estudo II indicou a inconsistência empírica do fator visual do QVV e a adequação psicométrica do fator que avalia preferências cognitivas verbais. O Estudo III não confirmou a expectativa de correlação entre preferências cognitivas (por palavras ou por imagens) e memória autobiográfica (tanto na recordação quanto no relato de eventos pessoais). No entanto, o teste t revelou diferenças significativas (p>0,01) entre dois grupos (Psicologia e Letras versus Odontologia e Biomedicina) quanto às variáveis: escore em estilo verbal, número de palavras e coerência narrativa. O grupo Psicologia e Letras apresentou os maiores escores nas três variáveis. Os resultados sugeriram a existência de um construto que abarca tanto estilo cognitivo verbal quanto características narrativas: perfil cognitivo verbalnarrativo. A análise quantitativa/qualitativa do Estudo IV apontou a proporção equilibrada entre descritores objetivos e subjetivos como condição para a obtenção de alta coerência narrativa. Além disso, verificou-se que características verbais e narrativas estavam alicerçadas em habilidades imaginativas. Este achado contradiz a freqüente concepção de que preferências verbais e imaginativas seriam polaridades excludentes, indicando interação entre estes dois processos cognitivos. / This research investigated the relationship among verbalizer-visualizer cognitive style, recall, and narrative expression of autobiographical events. One hundred and four undergraduate students were asked to complete four tasks: 1) Report of an Autobiographical Event; 2) Autobiographical Memory Questionnaire (AMQ); 3) Verbalizer-visualizer Questionnaire (VVQ); 4) Bett´s Questionnarie Upon Mental Imagery – Short Version. Factorial Analisys of Study I distinguished two factors in recalling of personal events: 1) pre-reflexive cognitive processes (poorly dependent on reflexive resources, such as imagery vivacity); 2) reflexive cognitive processes (such as evaluations concerning the event significance). Outcomes of Study II highlighted an empirical inconsistency of the visual factor of VVQ and appropriate psychometric properties of its verbal scores. In Study III the expected correlation between cognitive preferences (for words or images) and autobiographical memory (for recall and report of personal events) was not confirmed. However, a t test analysis indicated significant difference (p>0,01) between two groups (Psychology and Languages versus Odontology and Biomedicine) concerning the following variables: verbal scores, narrative coherence and narrative volume. Psychology and Languages students presented higher scores in such variables. A new construct is suggested in order to explain both verbal cognitive style and narrative characteristics: the verbal-narrative cognitive profile. Qualitative/quantitative analysis in Study IV indicated that a similar balance between objective and subjective narrative descriptors is needed to achieve high levels of narrative coherence. Moreover, it was observed that verbal and narrative characteristics depend upon imaginative skills. Thus, outcomes contradict the ordinary assumption that verbal and imaginative preferences should be taken as excluding polarities: an interaction between these two cognitive processes was found.

Emoção, prevalência e relevância pessoal de eventos em roteiros de vida em uma amostra brasileira

Felinto, Tuíla Maciel January 2017 (has links)
Roteiros de vida são um protótipo de trajetória de vida construído socialmente e com partilhado pelos membros de uma cultura e pode influenciar como indivíduos avaliam experiôncias anteriores e projetam seu futuro. Os participantes (384 brasileiros univcr sitú.rios) responderam quais sete eventos mais importantes acontecerão na vida de uma criança hipotética de sua cultura. A análise mostrou um roteiro de vida com alta coin cidência dos eventos citados, cúrnulo de eventos positivos esperados para acontecer entre 15 e 30 anos, além da predominância. de eventos positivos. Comparando os resultados com estudos realizados na Dinamarca, Estados Unidos: Turquia e Holanda, encontrou se uma estrutura semelhante em todos, mas também diferenças no conteúdo referentes a particularidades culturais O roteiro de vida brasileiro ó mais semelhante ao americano Apenas categorias de eventos relacionadas à morte foram consideradas negativas nessa amostra. Estudos futuros podem investigar variações nos roteiros de vida para diferentes grupos na população. / Life scripts are schcrnatic reprcscntations of the lifc history that are socially built and shared by the members of a cultnre and inflnences the way people evaluate their previons and prcsent cxperiences, and how thcy plan their future, A samplc of 384 Brazillians undergnuinates, answered which seven most important events are expected to happen in the life of a newborn in their own culture. Data showed a life script with an overlap of the evcnts: an a.ccurnulation of positivc cvents cxpected to happen bctween thc 15 and 30 ycars of age, anel a prcdominance of positive cvcnts.

Methodological issues of quantifying everyday memory phenomena with paper and electronic diaries

Laughland, Andrew January 2017 (has links)
Capturing life as it is lived is an important goal in psychology, and diary methods are commonly used for this purpose. They capture events near the time of their occurrence and are less prone to retrospective biases associated with questionnaire, interview and survey methods. However, participants in diary studies must remember to carry the diary with them, and find it convenient to make entries in timely fashion. New approaches, replacing paper diaries with technology (e.g. personal digital assistants), can overcome forgetting to make entries and retrospective filling of data. However, until recently technology had its own problems (e.g. unreliability and cost of devices, the need for training, biases of technical competence, etc.). The research described in this dissertation arose from the anticipation that the rapid, worldwide growth of smartphone ownership would overcome many of these limitations since participant-owned smartphone diaries can eliminate associated costs and facilitate increased rates of compliance. Six diary studies were conducted on two transient cognitive phenomena. Initially, a smartphone app was developed and compared with a paper diary in the study of involuntary autobiographical memories. Although participants in the smartphone-diary condition demonstrated significantly better compliance than those in the paper-diary condition by reliably carrying their smartphones, and promptly completing diary entries in the app, they recorded significantly fewer events than paper diary users. To test that this unexpected finding was not specific to involuntary autobiographical memories, the method was tested with everyday memory failures, and the same unexpected finding was obtained. Further studies manipulated the length of diary-keeping period and demonstrated a diary entry rate reduction effect with longer diary keeping periods, an effect seen in both paper- and participant-owned smartphone-diaries. For involuntary autobiographical memories, the effect was demonstrated by comparing 1-day and 7-day diaries, and also by using a 30-40 minutelong digital audio recording method. With everyday memory failures, the effect was demonstrated by comparing 7-day and 28-day diaries. The audio recording method was used to capture involuntary autobiographical memories while driving. It was also used on a campus walk and compared with a 1-day paper diary within-subjects, finding a higher rate of recording in the shorter period, and consistency of memory counts across two modes of recording. This novel audio-recording method facilitated much more detailed analysis of involuntary memory cues and chaining and enabled the evaluation of potential instances of priming. Finally, a telephone and postal-based diary study of everyday memory failures demonstrated the feasibility of recruitment and measurement of participants remotely, which can be particularly useful with older adults. Taken together, the results of this research make a significant methodological contribution to research on transient everyday cognitive phenomena by showing that (1) care is needed when using participant-owned smartphone diaries, (2) paper diaries may be more reliable than currently given credit, and (3) diary-recording periods can be substantially reduced without compromising the quantity and the quality of data obtained. In addition, results increase our theoretical understanding of two specific phenomena studied in this dissertation: involuntary autobiographical memories and everyday memory failures. The findings indicate that involuntary memories are much more frequent than previously thought, may represent a stable characteristic of a person and, in addition to immediately present cues, can be elicited by internal memory chaining process and more distant priming of events and thoughts. Finally, the absence of age effects in the frequency and nature of recorded everyday memory failures, together with significant negative age effects in laboratory tests of memory and cognition, is a novel finding that has significant implications for research on cognitive ageing.
