The time spent in sessions also ranges, with some studies being as short as fifteen minutes to other studies lasting forty minutes. Studies can take place in the lab, or even at home with researchers keeping in touch through weekly phone calls.
The effects are tested immediately after training is completed and again a few months after, or even up to a year later, to see if the training outcomes are still in place.
Testing and evaluation can be based on the measures of academic efficiency, ratings of the individual's symptoms from teachers and parents, comparing the experimental to the control groups of the study, and self-report measures.
There are many possible transfer effects from working memory training. An increase in working memory capacity could make individuals more likely to take on tasks that have a higher working memory load, such as math and other challenging academics.
Furthermore, there has been parent reported decreases of inattentive behaviours, hyperactivity, and impulsivity in children with ADHD,  in addition to a decrease in motor activity. Findings from these results vary according to which nontrained tasks the researcher chooses to use. The main general finding in these studies confirms that experimental groups improve on trained tasks in comparison to control groups, and that effects will need retraining to maintain.
The concept of working memory became widely accepted and its importance better understood across the s. At this time, a number of attempts to improve working memory were also initiated. While his capacity on this trained task had improved, his working memory: This was most clearly demonstrated when, asked to repeat letters instead of numbers, this same student with over hrs of practice at recalling digits could recall only six letters at a time: The effect of the training was not to improve the working memory system but to change the information being stored: In reality, his working memory capacity had not increased.
This study and others like it contributed to the prevailing assumption in the scientific community that working memory is a set characteristic that cannot be improved. Many clinical studies published in s and s claim that working memory training is an efficient strategy for mitigating effects of ADHD and other cognitive disorders. Georgia Institute of Technology researchers who reviewed 17 studies on WMT concluded that "the results are inconsistent" due to the fact that many studies had "inadequate controls" as well as "ineffective measurement of the cognitive abilities of interest.
In , a systematic meta-analytic review was undertaken. All studies had to have a treatment and a treated or untreated control group. By this time, some twenty-three studies met these criteria, including both clinical samples of typically developing children and adults. The results closely replicated the original finding by Ericcson et al. While the results were conclusive for ADHD population, there was no convincing evidence for transfer or generalization effects indicating improved capacity in typically developing children and healthy adults.
Other researchers have studied the effects of training on children with attention issues. In the February edition of Science , Klingberg and colleagues, led by F McNab, claimed that adaptive span training had led to changes in dopamine D1 and D2 receptors. The results were not reported.
Moreoever, research at the Wallenberg Neuroscience Center in Sweden indicates that working memory training may decrease hippocampal neurogenesis. When experimental medical scientists trained adult male rats in a working memory task for 4 or 14 days, rats trained for two weeks had fewer newborn hippocampal neurons than those that were only trained for 4 days.
The report suggests that increased stress , caused by an intense training of working memory, can reduce the production of hippocampal neurons. Lack of credible evidence of efficacy is increasingly highlighted in popular media.
From Wikipedia, the free encyclopedia. Br J Educ Psychol. Evidence of transfer and maintenance effects". If recalling a memory is like climbing a hill, then being reminded of it is like being dropped by helicopter on top of the hill. You enjoy the view, and it feels like you've accomplished something, but if you'd climbed to the top yourself, you'd have a better idea of how to get there next time. In other words, when you are tested for a memory, you actively re-create or rediscover it in a way that positively reinforces that memory.
There's an interesting correlate of this that takes place during sleep. Recent studies in neuroscience suggest the brain takes advantage of this "offline" period to repeat, and so select, what should be remembered in the long term. Principally, the brain seeks patterns that exist across different memories that have formed in the recent past.
As a result, it is often very helpful to review information you wish to remember just before you fall asleep. In the morning, what seemed complex and cloudy can appear surprisingly lucid. I recall once getting into the bizarre habit of not being able to remember Bob Dylan's name. Maybe six or seven times I'd try but fail to recall it. Each time, I'd think it would never happen again. This absurd image acted as a temporary crutch or scaffold, and in time my broken memory gradually healed.
This brings us to the question: We've all experienced the frustration of setting out confidently to find a familiar memory — the name of an actor or title of a book, for example — only to wind up empty-headed and confused. Intriguingly, this often happens with information that we know we know. The first thing to realise is that there's nothing remotely shameful or surprising about "failures" of recall.
As we've seen, a memory is never an isolated unit of information. There will always be plenty of implicit context or "components" to the memory: Think of these as routes into memory; they are ways of causing the full memory to become active and coercing your brain into reproducing the whole story.

Long term memory is the ongoing storage of unconscious and conscious information. It exists beyond your awareness but can be called into focus as needed. This type of memory can last for days - or decades. It is created from short term memories which are replayed and reconnected several times.

Exercise your working memory. Break down long items into smaller pieces. When you’re faced with a complex piece of information, try to break it down into small portions. Your short-term memory can hold between four and seven separate things at once. By leveraging this chunking technique, you can make each item carry more useful . A long-term memory is anything you remember that happened more than a few minutes ago. Long-term memories can last for just a few days, or for many years. Long-term memories aren't all of equal strength. Stronger memories enable you to recall an event, procedure, or fact on demand—for example, that Paris is the capital of France.
Episodic long term memory – This is the memory that is responsible for remembering events in your life. This is where your memory of September 11th is stored, a car accident or even your first day of school. Working memory training is intended to improve a person's working memory. Working memory is a central intellectual faculty, linked to IQ, ageing, and mental health.
