Dual-store models[ edit ] These models postulate that later study list items are retrieved from a highly accessible short-term buffer, i. An important prediction of such models is that the presentation of a distractor, for example solving arithmetic problems for 10—30 seconds, during the retention period the time between list presentation and test attenuates the recency effect. Since the STS has limited capacity, the distractor displaces later study list items from the STS so that at test, these items can only be retrieved from the LTS, and have lost their earlier advantage of being more easily retrieved from the short-term buffer.
This is the average daily time, so to recover the annual time spent, we simply multiply by Suppose we were interested in how much time a flashcard would cost us over 20 years. The average daily time changes every year the graph looks like an exponential decay, rememberso we have to run the formula for each year and sum them all; in Haskell: Spaced repetition can accommodate dozens of thousands of cards.
See the next section. To a lesser extent, one might wonder when one is in a hurry, should one learn something with spaced repetition and with massed? How far away should the tests or deadlines be before abandoning spaced repetition?
Quotidian uses, but all valuable to me. With a diversity of flashcards, I find my daily review interesting. Housman poetry, followed by a few quotes from LessWrong quote threadsand so on. This takes under 20 minutes, which is not too bad. By Februarythe daily reviews are in the 40s or sometimes 50s for similar reasons, but the gradual shrinkage will continue.
We can see this vividly, and we can even see a sort of analogue of the original forgetting curve, if we ask Mnemosyne 2. But because it is using spaced repetition, keeping up is easy. Other forms of memory are still more powerful.
Marcus says the other instances of hyperthymesia resemble Price. When to review When should one review? The studies demonstrating the spacing effect do not control or vary the time of day, so in one sense, the answer is: So one reviews at whatever time is convenient.
Convenience makes one more likely to stick with it, and sticking with it overpowers any temporary improvement. Memory consolidation seems to be related, and sleep is known to powerfully influence what memories enter long-term memory, strengthening memories of material learned close to bedtime and increasing creativity ; interrupting sleep without affecting total sleep time or quality still damages memory formation in mice So reviewing before bedtime would be best.
Other mental exercises show improvement when trained before bedtime; for example, dual n-back.This was the only significant effect (at 5% level) in the model, none of the factors had any effect on the ratings for the dummy wine.
Table 4. Effect of session number and contextual factors on liking for the dummy wine (results from ANOVA).
Since every physiotherapy treatment determines a specific and a contextual effect, physiotherapists should manage the contextual factors as a boosting element of any manual therapy to improve placebo effects and avoid detrimental nocebo effects. Our self-esteem, the general self evaluation one makes of oneself, can vary throughout life – particularly during major life changes.
It’s no wonder then that during the changes and challenges of adolescence there can be significant fluctuations in a teenager’s assessment of their own self-image and/or self-worth.
Contextual effect modifiers were identified when authors incidentally reported factors beyond the intervention, which may have led to differences in outcome between randomisation units (mainly health facilities) within the trial, or contributed to the overall reported trial effect size.

Hattie Effect Size Results. I first heard about John Hattie and his work on effect sizes in when he published his article Influences On Student Learning..
At the time, Hattie was at pains to point out that nearly everything we do in the classroom helps students to learn.
