Spaced repetition

When should one review? In the morning? In the evening? Any old time? The studies demonstrating the spacing effect do not control or vary the time of day, so in one sense, the answer is: it doesn’t matter – if it did matter, there would be considerable variance in how effective the effect is based on when a particular study had its subjects do their reviews.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.If one is not satisfied with that answer, then on general considerations, one ought to review before bedtime & sleep. 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
