Why Is Memory Considered An Active Reconstructive Process

Most Effective Way to IMPROVE MEMORY (& Memorize ANYTHING)

In cognitive biology, memory is considered to be an active reconstructive process because it is influenced by many other cognitive processes such as imagination, perception and semantic memory. It is associated with episodic encoding of several incidents as well as retrieval that helps in the reconstructive process.

Natural Ways To Improve Your Memory

Everyone has moments of forgetfulness from time to time, especially when life gets busy.

While this can be a completely normal occurrence, having a poor memory can be frustrating.

Genetics plays a role in memory loss, especially in serious neurological conditions like Alzheimers disease. However, research has shown that diet and lifestyle have a major impact on memory too.

Here are 14 evidence-based ways to improve your memory naturally.

Heuristic Processing: Availability And Representativeness

Another way that our information processing may be biased occurs when we use heuristics, which are information-processing strategies that are useful in many cases but may lead to errors when misapplied. Lets consider two of the most frequently applied heuristics: the representativeness heuristic and the availability heuristic.

In many cases we base our judgments on information that seems to represent, or match, what we expect will happen, while ignoring other potentially more relevant statistical information. When we do so, we are using the representativeness heuristic. Consider, for instance, the puzzle presented in Table9.4> Table 9.4, The Representativeness Heuristic. Lets say that you went to a hospital, and you checked the records of the babies that were born today. Which pattern of births do you think you are most likely to find?

Table 9.4 The Representativeness Heuristic.

Using the representativeness heuristic may lead us to incorrectly believe that some patterns of observed events are more likely to have occurred than others. In this case, list B seems more random, and thus is judged as more likely to have occurred, but statistically both lists are equally likely.

Strategies To Enhance Encoding And Retrieval

Learning experience designers can use strategies that enhance encoding and retrieving information and skills, as explained below.

  • Use elaboration strategies to facilitate the transfer of information into long-term memory. Some elaboration strategies include: thinking of related ideas or examples of the content, mentally tying the information together or creating a mental image of the information. Course designers and instructors can encourage this behavior.
  • Use the same type of elaboration for encoding that learners will need for retrieval.
  • Make purposeful connections and associations with prior knowledge to improve transfer to long-term memory.
  • Organize information by categorizing it into subsets to facilitate storage and retrieval. Many people do this spontaneously and instructional designers spend a great deal of effort at organizing information into meaningful chunks.
  • Provide distributed practice across multiple study sessions rather than concentrating the same amount of practice into one session. This allows information to be consolidated into memory over time, improving retention.
  • Help learners associate facts with a personal experience to improve recall. Pairing semantic memories with episodic memories facilitates learning.

    Salience And Cognitive Accessibility


    Still another potential for bias in memory occurs because we are more likely to attend to, and thus make use of and remember, some information more than other information. For one, we tend to attend to and remember things that are highly salient, meaning that they attract our attention. Things that are unique, colourful, bright, moving, and unexpected are more salient . In one relevant study, Loftus, Loftus, and Messo showed people images of a customer walking up to a bank teller and pulling out either a pistol or a chequebook. By tracking eye movements, the researchers determined that people were more likely to look at the gun than at the chequebook, and that this reduced their ability to accurately identify the criminal in a lineup that was given later. The salience of the gun drew peoples attention away from the face of the criminal.

    Box : Educational Applications

    In daily life, we can use above-mentioned techniques to facilitate learning and long-term memory formation. In general, it appears that encoding and retrieval are processes during which we can and should focus on checking our schema and adding episodic details. Conversely, memory consolidation is a process during which we, mostly unconsciously, extract commonalities and expand schemas, often at the cost of specific details. So, in order to ensure a good balance between semantic and episodic memories in educational settings, we can follow these tricks:

  • 1.

    Elaborate where you can, both during encoding and retrieval. Use a wide range of knowledge and senses to make a memory as vivid as possible, yet also connected to prior knowledge. Considering how the hippocampus uses spatial properties to learn, e.g., by using the method of loci, can help.

  • 2.

    Reactivate prior knowledge when you learn new information, not only to connect old and new information, but also to be able to apply retrieval practice strategies to strengthen already existing knowledge and find links between newly learned information and existing knowledge. This way, you can best find a balance between memory for details and gist knowledge.

  • 3.

    Use breaks wisely. Space and interleave your studying and repeat, most optimally through retrieval, information on separate days. This allows you to accommodate spacing and consolidation effects that help you to semanticize information and build strong schemas.

  • What Kind Of Retrieval Practice Questions Should I Use

    Any kind of practice question can and should be used during retrieval practice. Short answer, essay, or multiple choice would all work great as long as you also use spacing retrieval. Any of these methods will let you know what students really know.

    Some Useful Research Findings

    Research inspired by Schema Theory has shown that we do seem to be able to parameterize movements. For example, we can perform handwriting slowly or quickly, large or small, and it still looks like our handwriting.

    However, parameters can be more sophisticated than Schmidt originally suggested. For example, we can walk carrying a variety of burdens and this involves more than just increasing the strength of all muscle contractions. For example, swinging a leg forward is the same regardless of the load but pushing a leg back is harder with a heavy load.

    It also appears that we perform better in conditions where we have had a lot of practice. For example, taking a free throw in basketball is always done from the same spot and people get especially good at shooting from that spot.

    The reason for this is not known, but it is obvious that it is possible for a Recall Schema to be more accurate in some conditions than in others, and it is likely that its weaknesses are going to be in conditions where we have had little or no experience. In other words, we should expect calibration to be ‘local’, meaning that experience with a particular condition helps us most to calibrate to that condition and to conditions very similar to it.

    So, focus on form at first and forget the ball. Then introduce the ball and try to learn to vary your movements correctly for the different conditions of each shot.

    Eat Berries For Better Long

    Another diet-related effect on memory is the mounting research that eating berries can help to stave off memory decline.

    A study from the University of Reading and the Peninsula Medical School found that supplementing a normal diet with blueberries for twelve weeks improved performance on spatial working memory tasks. The effects started just three weeks in and continued for the length of the study.

    A long-term berry study that tested the memory of female nurses who were over 70 years old found that those who had regularly eaten at least two servings of strawberries or blueberries each week had a moderate reduction in memory decline. .

    More research is needed in this area, but science is getting closer to understanding how berries might affect our brains. In particular, blueberries are known for being high in flavanoids, which appear to strengthen existing connections in the brain. That could explain why theyre beneficial for long-term memory.

    Learning And Memory Schemas Build Competence

    Posted December 11, 2012

      In October I attended a memory schema symposium at the annual meeting of the Society of Neuroscience. This schema idea is that memory of prior learning provides an organized framework for new learning. That is, new information is evaluated according to pre-existing mnemonic schema, which may influence how readily new information transfers into memory.

      The notion of this kind of schema stems originally from Harry Harlows ideas back in the 1940s. Harlow showed that when a monkey learns a new kind of problem, he solves it by slow plodding trial and error. However, if he has experience with a large number of problems of a similar type or class, the trial and error is replaced by a process in which the individual problems are eventually solved insightfully. For example, if you learn how to do task A, B, and C, when presented with a new task D, you might say to yourself, I dont know how to do this task D, but it is like task B, and I do know how to do that! Thus, you have a leg up on learning how to do task D. The idea underlies how people become experts in a given field: their accumulated learning of various tasks provides them with a repertoire of what Harlow called learning sets that makes it easier to learn new things.

      What Is Retrieval Practice And Why Is It So Powerful

      So, what is retrieval practice, and why is it effective? Retrieval practice is a learning technique revolving around repeatedly recalling learned material without seeing it in front of you. There are a few ways to do this:

      • Flashcards
      • Writing Prompts
      • Elaborative Interrogation

      As teachers we know that late-night cramming sessions to study for a test is never the most effective. While students may be able to recall that information for the test, theyre likely to forget everything after the test is over.

      For real learning, we need to build retrieval practice into our lessons. This way we are training our students in the skills they need to succeed rather than just giving them the content.

      The success of retrieval practice is not anecdotal, it is based on research in cognitive science.

      Knowing how retrieval practice is defined will help you come to a deeper understanding of the practice, but that is not all you need to know.

      Knowing how retrieval practice works, how to use it, why it works, and who it works for are just a few of the things we will be talking about in this article.

      Why Does This Matter For Learning

      Connecting to SQL Server with MuleSoft AnyPoint 3.9 ...

      Learners are not blank slates waiting to be filled with knowledge they are ingrained with schemas that can both help and hinder learning. Any learning activity, if effective, is likely to result in a change to an existing schema. When you already have an existing mental model in long-term memory, cognitive load is reduced.

      Schemas can also be barriers to learning when learners hold incorrect or biased assumptions, or associate negative experiences with a topic. You can help learners connect new information to these existing mental models and anticipate misinformation by using these four simple strategies:

      1. Surface existing schemas early

      This tip applies both to the instructional design process and the learning experience itself. Always center your design around the learners schema. And, when it comes to understanding your learners lived experiences, a SME or stakeholder opinion isnt enough. First-hand, qualitative information collected from surveys, interviews, and focus groups is the best way to immerse yourself in your learners world so you can build a course that is relevant, meaningful, and contextually relatable.

      2. Keep the entire learning journey in mind

      3. Put new information into the context of existing schemas

      4. Reduce extraneous cognitive load

      Day : Schema Learning And Practice

      Figure 2. Screen shots from the learning phase of the face-to-home association task. Encoding phase: subjects observed the faces moving to their corresponding home. Retrieval phase with feedback: subjects were asked to select the home that was associated with the face. Feedback was provided by presenting the wrong home in red, and subsequently the correct home in green. Retrieval phase with confidence rating: subjects were asked to select the home corresponding to the face and to make a confidence judgment thereafter. The small pink circle is the cursor that the subjects had to move to make their choice.

      Importantly, there was no systematic relation between homes and screen locations. However, for a particular face-home association the home always appeared on the same location. Hence, the location of the home can be seen as a contextual aspect to the more central face-home association that could be implicitly learned during the task.

      At the end of the practice session, subjects needed to have a good understanding of the task layout. Subjects who did not pick the correct homes for at least 9 out of 12 schema-congruent faces and 6 out of 12 incongruent faces were excluded from the experiment. We reasoned that subjects who did not meet this criterion did not have a good understanding of the task, which required switching between schema and non-schema strategies in order to obtain maximum performance.

      Running A Proof Of Concept

      To help discover issues with your environment in early phases of your database migration, we recommend that you run a small test migration. Doing this can also help you to set a more realistic migration time line. In addition, you might need to run a full-scale test migration to measure whether AWS DMS can handle the throughput of your database over your network. During this time, we recommend to benchmark and optimize your initial full load and ongoing replication. Doing this can help you to understand your network latency and gauge overall performance.

      At this point, you also have an opportunity to understand your data profile and how large your database is, including the following:

      • How many tables are large, medium, and small in size.

      • How AWS DMS handles data type and character-set conversions.

      • How many tables having large object columns.

      • How long it takes to run a test migration.

      Schema Theory In Sports


      If youve ever wondered how your brain actually learns new skills, much of the answer has to do with Schmidts Schema Theory. Schema Theory, especially in sports, involves Generalized Motor Programs, Recall Memory, and Recognition Memory, and discusses how the brain uses them to learn and improve. In boxing, Recognition Memory is critical to improving your form and technique every time you train.

      What is Recognition Memory?

      Recognition Memory is the part of your brain that tracks a movement to ensure youre completing it correctly. If your brain decides that you didnt perform a specific movement properly, it makes a note and remembers the feeling for future reference. Recognition Memory only works if you have enough information about the performance of a specific skill.

      When it comes to boxing, you may not have all the knowledge you need for accurate memory recognition. But with the help of our coaches, you can train your body and your brain to gain an understanding of how each punch, slip, and step should be performed.

      Training the Brain

      According to Schema Theory as it applies to sports and boxing, when performing a certain punch, like the jab, you may already know that a jab is not a straight right hand, a hook, or an uppercut, but the specifics of the way you perform the move can still change.

      How Does Memory Work

      In its simplest form, memory refers to the continued process of information retention over time. It is an integral part of human cognition, since it allows individuals to recall and draw upon past events to frame their understanding of and behavior within the present. Memory also gives individuals a framework through which to make sense of the present and future. As such, memory plays a crucial role in teaching and learning. There are three main processes that characterize how memory works. These processes are encoding, storage, and retrieval .

    • Encoding. Encoding refers to the process through which information is learned. That is, how information is taken in, understood, and altered to better support storage . Information is usually encoded through one of four methods: Visual encoding acoustic encoding semantic encoding and tactile encoding . While information typically enters the memory system through one of these modes, the form in which this information is stored may differ from its original, encoded form .
    • Retrieval. As indicated above, retrieval is the process through which individuals access stored information. Due to their differences, information stored in STM and LTM are retrieved differently. While STM is retrieved in the order in which it is stored , LTM is retrieved through association .
