Amnesia of aversive experiences may minimize chance of developing psychological trauma. To the best of our knowledge, there is no systematic review to specifically address this topic. The aim of this study was to search for scientific evidence on the amnesic effect of different sedatives in pediatric patients undergoing medical or dental procedures. Methods: Throughout October 2015, electronic databases, such as Public Medical Literature Analysis and Retrieval System Online (PubMed), Scopus and the Cochrane Library, clinical trial registries and grey literature were searched. Randomized controlled trials that assess amnesia of events that ocurred prior to or during health procedures, in children and adolescents 1–19 years old receiving sedative drugs were included. Two calibrated reviewers (Kappa≥0,8) selected articles. After confirming eligibility, data extraction was carried out and assessment of risk of bias was performed according to the 'Cochrane Collaboration's Tool for Assessing Risk of Bias in Randomized Trials'. Disagreement at all levels were resolved by consensus or by involving a third reviewer. Results: Fifty-two studies were included in this systematic review. Anterograde amnesia was observed in nearly all seventeen studies that compared sedatives with placebo. Among the twelve trials that assessed variations of the same sedative regimen, just three found greater anterograde amnesia when increased dose or different time of administration was used. Retrograde amnesia was assessed only in nine studies, and most of them found that sedatives did not affect recall of information acquired before sedative administration. Benzodiazepines are the most studied sedatives and showed greater ocurrence of anterograde amnesia. Most studies were at unclear risk of bias and the overall quality of the evidence was low. Conclusion: The scientific evidente on the amnesic effects of sedatives in children and adolescents is limited. Benzodiazepines showed to induce anterograde amnesia, but it is a weak evidence. This systematic review point out the necessity of further clinical trials that focus on memory as a primary outcome. / Proposição: Alguns medicamentos usados para sedação de crianças e adolescentes podem suprimir temporariamente a memória, o que pode ser benéfico para pacientes que, embora sedados, apresentam medo, ansiedade ou problemas de comportamento durante procedimentos médicos e odontológicos. Amnésia de experiências aversivas pode minimizar a chance de ocorrência de futuros traumas psicológicos. Não foi encontrada, na literatura, revisão sistemática que aborde especificamente esse tema. O objetivo deste estudo foi verificar as evidências científicas sobre os efeitos amnésicos de diferentes sedativos em pacientes pediátricos submetidos a procedimentos médicos e odontológicos. Métodos: Em outubro de 2015, realizou-se a busca por estudos publicados e não publicados em registros de ensaios clínicos, literatura cinzenta e bases de dados eletrônicas, como Public Medical Literature Analysis and Retrieval System Online (PubMed), Scopus e The Cochrane Library. Foram incluídos ensaios clínicos randomizados e controlados que avaliaram amnésia de eventos ocorridos antes e durante procedimentos em saúde, em pacientes de 1 a 19 anos submetidos à sedação. Os artigos foram selecionados de forma independente por dois pesquisadores calibrados (Kappa ≥ 0,8). Após confirmação da elegibilidade, foi realizada extração de dados e avaliação do risco de viés de acordo com a 'Cochrane Collaboration’s Tool for Assessing Risk of Bias in Randomized Trials'. Em todas as etapas, discordâncias foram resolvidas por consenso ou com auxílio de um terceiro pesquisador. Resultados: 52 estudos foram incluídos nesta revisão sistemática. Amnésia anterógrada foi obervada em quase todos os 17 estudos que compararam sedativos com placebo. Entre os 12 estudos que avaliaram variações do mesmo sedativo (dose, via e tempo de administração), apenas 3 encontraram maior ocorrência de amnésia anterógrada quando se utilizou maior dose (n=2) e quando se variou o tempo de administração (n=1). Amnésia retrógrada foi avaliada em apenas 9 estudos e, na maioria deles (n=7), os sedativos não afetaram a recordação de eventos anteriores à administração do medicamento. Os benzodiazepínicos foram os sedativos mais estudados e os que apresentaram maior ocorrência de amnésia anterógrada. A maioria dos estudos (n=31) apresentou incerto risco de viés, e a qualidade geral da evidência foi baixa. Conclusão: As evidências científicas sobre os efeitos amnésicos dos sedativos em crianças e adolescentes são limitadas. Os benzodiazepínicos demonstraram induzir amnésia anterógrada, mas a evidência é fraca. Esta revisão destaca a necessidade de novos ensaios clínicos que avaliem, especialmente, a memória como desfecho primário.

The hippocampal dependence of long-term declarative memory

Alvarez Svahn, Rodrigo January 2015 (has links)
Investigations into the neural correlates of memory have found the hippocampus to be a crucial structure for long-term declarative memories, but the exact nature of this contribution remains under debate. This paper covers three theories concerned with how the hippocampus is involved in long-term memory, namely the Standard Consolidation Model, the Multiple-Trace Theory, and the Distributed Reinstatement Theory. According to the Standard Consolidation Model, long-term declarative memories (both episodic and semantic) are dependent on the hippocampus for a limited time during which the memories undergo a process of consolidation, after which they become dependent on the neocortex. In contrast, the Multiple-Trace Theory argues that detailed and context-specific episodic (but not semantic) memories remain dependent on the hippocampus indefinitely. While both the aforementioned theories posit that memories are initially dependent on the hippocampus, the Distributed Reinstatement Theory does not. Advocates of this theory propose that several memory systems compete for the encoding of a memory, and that the hippocampus usually is the dominant system. However, it is also suggested that the other (unspecified) memory systems can overcome the hippocampal dominance through extensive and distributed learning sessions. In this paper, findings from both human and rodent studies focusing on the hippocampus are reviewed and used to evaluate the claims made by each theory on a systems level.

Towards Recollection

Kalle, Cornelia January 2023 (has links)
We all take the natural environment we encounter during childhood as the norm against which we measure environmental degradation later in our lives. With each ensuing generation, the amount of environmental degradation increases, but each generation in its youth takes that degraded condition as the non degraded condition - as the normal experience. This psychological phenomenon is called environmental generational amnesia, and has just recently been stated as one of the most pressing psychological problems of our lifetime. More meaningful and frequent interactions with the natural environment can clarify the confusion about what Nature really is and strengthen our relationship to it, which in turn could encourage us to preserve natural environments for the coming generations. In this way, being in Nature and appreciating it could prevent environmental generational amnesia. The BA-project Towards Recollection aims to raise the question about environmental degradation as a result of environmental generational amnesia and explore how Nature in an urbanscape could be highlighted through a group of architectural interventions and the sensory experiences of Nature, to work as a tool on our journey towards recollection and in the prevention of one of the most pressing psychological problems of our lifetime.

Amnesia and future thinking: Exploring the role of memory in the quantity and quality of episodic future thoughts

Cole, S.N., Morrison, Catriona M., Barak, O., Pauly-Takas, K., Conway, M.A. 21 August 2015 (has links)
Yes / Objectives To examine the impact of memory accessibility on episodic future thinking. Design Single-case study of neurological patient HCM and an age-matched comparison group of neurologically Healthy Controls. Methods We administered a full battery of tests assessing general intelligence, memory, and executive functioning. To assess autobiographical memory, the Autobiographical Memory Interview (Kopelman, Wilson, & Baddeley, 1990. The Autobiographical Memory Interview. Bury St. Edmunds, UK: Thames Valley Test Company) was administered. The Past Episodic and Future Episodic sections of Dalla Barba's Confabulation Battery (Dalla Barba, 1993, Cogn. Neuropsychol., 1, 1) and a specifically tailored Mental Time Travel Questionnaire were administered to assess future thinking in HCM and age-matched controls. Results HCM presented with a deficit in forming new memories (anterograde amnesia) and recalling events from before the onset of neurological impairment (retrograde amnesia). HCM's autobiographical memory impairments are characterized by a paucity of memories from Recent Life. In comparison with controls, two features of his future thoughts are apparent: Reduced episodic future thinking and outdated content of his episodic future thoughts. Conclusions This article suggests neuropsychologists should look beyond popular conceptualizations of the past–future relation in amnesia via focussing on reduced future thinking. Investigating both the quantity and quality of future thoughts produced by amnesic patients may lead to developments in understanding the complex nature of future thinking disorders resulting from memory impairments. / Institute of Psychological Sciences, University of Leeds

Adult recollections of childhood memories: What details can be recalled?

Wells, C.E., Morrison, Catriona M., Conway, M.A. 12 November 2013 (has links)
No / In a memory survey, adult respondents recalled, dated, and described two earliest positive and negative memories that they were highly confident were memories. They then answered a series of questions that focused on memory details such as clothing, duration, weather, and so on. Few differences were found between positive and negative memories, which on average had 4/5 details and dated to the age of 6/6.5 years. Memory for details about activity, location, and who was present was good; memory for all other details was poorer or at floor. Taken together, these findings indicate that (full) earliest memories may be considerably later than previously thought and that they rarely contain the sort of specific details targeted by professional investigators. The resulting normative profile of memory details reported here can be used to evaluate overly specific childhood autobiographical memories and to identify memory details with a low probability of recall.

Fictional first memories

Akhtar, Shazia, Justice, L.V., Morrison, Catriona M., Conway, M.A. 17 July 2018 (has links)
Yes / In a large-scale survey, 6,641 respondents provided descriptions of their first memory and their age when they encoded that memory, and they completed various memory judgments and ratings. In good agreement with many other studies, where mean age at encoding of earliest memories is usually found to fall somewhere in the first half of the 3rd year of life, the mean age at encoding here was 3.2 years. The established view is that the distribution around mean age at encoding is truncated, with very few or no memories dating to the preverbal period, that is, below about 2 years of age. However, we found that 2,487 first memories (nearly 40% of the entire sample) dated to an age at encoding of 2 years and younger, with 893 dating to 1 year and younger. We discuss how such improbable, fictional first memories could have arisen and contrast them with more probable first memories, those with an age at encoding of 3 years and older.

Människan som skapare, eller Den moderne Gud : Skapelseberättelsen som den skildras i Clay och Amnesia: A Machine for Pigs genom Milton och Shelley / Man as creator, or The modern God : The creation myth as it is portrayed in Clay and Amnesia: A Machine for Pigs through Milton and Shelley

Nordmark, Ida January 2018 (has links)
This thesis concerns the themes of godhood and creation in modern, secular works. Using literary analysis, the thesis examines how the creation myth and the relationship between creator and creation is written in David Almond’s novel Clay and the video game Amnesia: A Machine for Pigs, in comparison with how the same relationship is presented in Frankenstein and Paradise Lost. The thesis focuses on how the different works portray the themes of god, creation, original sin, and atonement, where the portrayals differ and where are the same. It ends with a discussion on how modern, secular stories using these themes manage to separate themselves from their religious origins while still remaining true to their inspirations. / Denna uppsats behandlar ämnena gudomlighet och skapelse i moderna, sekulära verk. Genom att använda litterär analys undersöker uppsatsen hur skapelseberättelsen och förhållandet mellan skapare och skapelse skildras i David Almonds roman Clay och datorspelet Amnesia: A Machine for Pigs i jämförelse med hur samma förhållande presenteras i Frankenstein och Paradise Lost. Uppsatsen fokuserar på hur de olika verken skildrar temana gud, skapelsen, syndafallet och försoningen, samt skillnader och likheter i skildringarna. Den avslutas med en diskussion om hur moderna, sekulära berättelsen som använder dessa teman separerar sig från sitt religiösa ursprung men ändå förblir trogna sina inspirationer.
