Auditory Feedback Blocks Memory Benefits of Cueing During Sleep
ARTICLE Received 26 Feb 2015 | Accepted 25 Sep 2015 | Published 28 Oct 2015 DOI: 10.1038/ncomms9729 OPEN Auditory feedback blocks memory benefits of cueing during sleep Thomas Schreiner1,2, Mick Lehmann1,3 & Bjo¨rn Rasch1,2,4 It is now widely accepted that re-exposure to memory cues during sleep reactivates memories and can improve later recall. However, the underlying mechanisms are still unknown. As reactivation during wakefulness renders memories sensitive to updating, it remains an intriguing question whether reactivated memories during sleep also become susceptible to incorporating further information after the cue. Here we show that the memory benefits of cueing Dutch vocabulary during sleep are in fact completely blocked when memory cues are directly followed by either correct or conflicting auditory feedback, or a pure tone. In addition, immediate (but not delayed) auditory stimulation abolishes the characteristic increases in oscillatory theta and spindle activity typically associated with successful reactivation during sleep as revealed by high-density electroencephalography. We conclude that plastic processes associated with theta and spindle oscillations occurring during a sensitive period immediately after the cue are necessary for stabilizing reactivated memory traces during sleep. 1 Department of Psychology, University of Zurich, 8050 Zurich, Switzerland. 2 Department of Psychology, University of Fribourg, 1701 Fribourg, Switzerland. 3 Psychiatric University Hospital Zurich, Clinic of Affective Disorders and General Psychiatry, 8032 Zurich, Switzerland. 4 Zurich Center for Interdisciplinary Sleep Research (ZiS), 8091 Zurich, Switzerland.

The Spaced Interval Repetition Technique
The Spaced Interval Repetition Technique What is it? The Spaced Interval Repetition (SIR) technique is a memorization technique largely developed in the 1960’s and is a phenomenal way of learning information very efficiently that almost nobody knows about. It is based on the landmark research in memory conducted by famous psychologist, Hermann Ebbinghaus in the late 19th century. Ebbinghaus discovered that when we learn new information, we actually forget it very quickly (within a matter of minutes and hours) and the more time that passes, the more likely we are to forget it (unless it is presented to us again). This is why “cramming” for the test does not allow you to learn/remember everything for the test (and why you don’t remember any of it a week later). SIR software, notably first developed by Piotr A. Woźniak is available to help you learn information like a superhero and even retain it for the rest of your life. The SIR technique can be applied to any kind of learning, but arguably works best when learning discrete pieces of information like dates, definitions, vocabulary, formulas, etc. Why does it work? Memory is a fickle creature. For most people, to really learn something, we need to rehearse it several times; this is how information gets from short‐term memory to long‐ term memory. Research tells us that the best time to rehearse something (like those formulas for your statistics class) is right before you are about to forget it. Obviously, it is very difficult for us to know when we are about to forget an important piece of information. -

Unrated = - Poor = Average = Good = Very Good = Essential = Open Office http://www.openoffice.org/ Very Good = Word processor, Spreadsheet, Drawing Package, Presentation Package etc, etc. Free and open source complete office suite, equivalent to Microsoft Office. Since the takeover of this project by Oracle development seems to have ground to a halt with the departure of many of the developers. Libre Office http://www.libreoffice.org/ Essential = Word processor, Spreadsheet, Drawing Package, Presentation Package etc, etc. Free and open source complete office suite, equivalent to Microsoft Office. This package is essentially the same as Open Office however it satisfies the open source purists because it is under the control of an open source group rather than the Oracle Corporation. Since the takeover of the Open Office project by Oracle many of the developers left and a lot of them ended up on the Libre Office project. Development on the Libre Office project is now ahead of Open Office and so Libre Office would be my preferred office suite.

Learning Efficiency Correlates of Using Supermemo with Specially Crafted Flashcards in Medical Scholarship
Learning efficiency correlates of using SuperMemo with specially crafted Flashcards in medical scholarship. Authors: Jacopo Michettoni, Alexis Pujo, Daniel Nadolny, Raj Thimmiah. Abstract Computer-assisted learning has been growing in popularity in higher education and in the research literature. A subset of these novel approaches to learning claim that predictive algorithms called Spaced Repetition can significantly improve retention rates of studied knowledge while minimizing the time investment required for learning. SuperMemo is a brand of commercial software and the editor of the SuperMemo spaced repetition algorithm. Medical scholarship is well known for requiring students to acquire large amounts of information in a short span of time. Anatomy, in particular, relies heavily on rote memorization. Using the SuperMemo web platform1 we are creating a non-randomized trial, inviting medical students completing an anatomy course to take part. Usage of SuperMemo as well as a performance test will be measured and compared with a concurrent control group who will not be provided with the SuperMemo Software. Hypotheses A) Increased average grade for memorization-intensive examinations If spaced repetition positively affects average retrievability and stability of memory over the term of one to four months, then consistent2 users should obtain better grades than their peers on memorization-intensive examination material. B) Grades increase with consistency There is a negative relationship between variability of daily usage of SRS and grades. 1 https://www.supermemo.com/ 2 Defined in Criteria for inclusion: SuperMemo group. C) Increased stability of memory in the long-term If spaced repetition positively affects knowledge stability, consistent users should have more durable recall even after reviews of learned material have ceased. -

A Spaced-Repetition Approach to Enhance Medical Student Learning and Engagement in Pharmacology
A Spaced-Repetition Approach to Enhance Medical Student Learning and Engagement in Pharmacology Dylan Jape Monash University Jessie Zhou Monash University Shane Bullock ( [email protected] ) Monash University Research Article Keywords: pharmacology, spaced-repetition, ashcards, medical education Posted Date: July 12th, 2021 DOI: https://doi.org/10.21203/rs.3.rs-625499/v1 License: This work is licensed under a Creative Commons Attribution 4.0 International License. Read Full License Page 1/20 Abstract Background: Pharmacology is a cornerstone of medical education as it underlies safe prescribing practices. However, medical students have reported unease regarding their perceived prociency in clinical pharmacology. Despite the signicant impetus to improve student outcomes, there is little analysis available of the techniques used by medical students to learn, retain and apply pharmacology knowledge. Methods: A mixed methods, student-focused approach was conducted to design and rene specic resources developed to address gaps in pharmacology education. This methodology comprised an anonymised scoping survey, followed by structured focus group interviews. We developed a relevant and time ecient resource to support long-term revision for academic and clinical success. These resources were released to a cohort of 100 graduate preclinical medical students who were invited at the end of year to evaluate the intervention via a subsequent anonymous survey. Results: The scoping survey received 103 complete responses. Surveys and focus group interviews revealed that only 50% of students engage in ongoing revision. The analysis identied in-semester revision of pharmacology as a signicant predictor of strategic and deep learning methods and improved quiz performance (a 5% higher score on average), compared to supercial learning methods. -
Retrieval Practice: Which Factors Should Educators Pay Attention
ARTIGO DOI: http://dx.doi.org/10.1590/2175-35392020220284 Elocid - e220284 PRÁTICA DE LEMBRAR: A QUAIS FATORES OS EDUCADORES DEVEM SE ATENTAR? Roberta Ekuni 1 ; Sabine Pompeia 2 RESUMO A prática de lembrar (retrieval practice) ou efeito da testagem (testing-effect) é uma estratégia de estudo que envolve tentar lembrar informações às quais fomos anteriormente expostos. Embora essa prática aumente o tempo de retenção de informações comparada às formas tradicionais de estudar, dentre várias outras vantagens com ampla evidência científica, essa estratégia não costuma ser a mais usada entre alunos. Educadores devem, assim, auxiliar estudantes a utilizarem essa estratégia em seu cotidiano. Com o intuito de otimizar sua aplicabilidade, o presente artigo discute quais fatores interferem nessa prática, incluindo: a importância de feedback, a forma com que a prática de lembrar é realizada e o formato de resposta dos alunos, o número de repetições de tentativas de recordar informações e o intervalo entre essas repetições. A apropriação do conhecimento sobre esses fatores influencia positivamente a implantação da técnica em sala de aula, promovendo assim uma educação baseada em evidências. Palavras-chave: processos cognitivos; aprendizagem; memória. Retrieval practice: which factors should educators pay attention to? ABSTRACT The retrieval practice or testing - effect, is a study technique that involves trying to remember information to which we were previously exposed. Although this practice increases the long term-retention of information compared to traditional study techniques, among several other advantages with ample scientific evidence, this strategy is not usually the most used among students. Educators should help students to use this technique in their daily lives. -

MindMapping Frank Sapp Technology and Training Specialist [email protected] MindMapping MindMapping • Introduction • Defined • Brief History • Subtopic 3 • Types Defined • A mind map is a diagram used to visually organise information. A mind map is often created around a single concept, drawn as an image in the center of a blank landscape page, to which associated representations of ideas such as images, words and parts of words are added. Major ideas are connected directly to the central concept, and other ideas branch out from those. Brief History • Early • Tony Buzan • Data Visualization • Research Early • Radial Maps • Spider Diagrams Radial Maps • Spider Diagrams • Tony Buzan • Video Data Visualization • Edward Tufte • Napoleon Russian Invasion • PowerPoint Edward Tufte • Napoleon Russian Invasion • Napoleon Russian Invasion • The graph displays several variables in a single two-dimensional image: • the size of the army - providing a strong visual representation of human suffering, e.g. the sudden decrease of the army's size at the battle crossing the Berezina river on the retreat; • the geographical co-ordinates, latitude and longitude, of the army as it moved; • the direction that the army was traveling, both in advance and in retreat, showing where units split off and rejoined; • the location of the army with respect to certain dates; and • the weather temperature along the path of the retreat, in another strong visualisation of events (during the retreat "one of the worst winters in recent memory set in"[1]). • Étienne-Jules Marey first called notice to this dramatic depiction of the fate of Napoleon's army in the Russian campaign, saying it "defies the pen of the historian in its brutal eloquence"[citation needed].
