50% improvement in learning from this sleep technique.
The quality could be related to career, parenthood, activism, religion, family ties, artistic endeavours, or many other things.
Doing this exercise for 20 minutes can improve your long-term memory by 20 percent.
Both functions are vital for the operation of memory, self-control, math, language and reading.
The spacing effect in learning was discovered over 100 years ago, but scientist are only now beginning to understand it.
Schacter’s ‘seven sins of memory’ are transience, absent-mindedness, blocking, misattribution, suggestibility, bias and persistence.

“Memory itself is an internal rumour.” –George Santayana
The word rumour captures an aspect of memory perfectly.
When we delve backwards, moments never return in their original clarity; they return as rumours of the original event.
Faces have been switched, names deleted, words edited – sometimes it’s as though we weren’t even there.
Psychologists have found that right from the moment an event occurs, is laid down in memory (or not), to the moment we try to retrieve it (or can’t), our minds are fallible.
Harvard psychologist Professor Daniel L. Schacter has classified memory’s slips, ambiguities and downright lies into the ‘seven sins of memory’: transience, absent-mindedness, blocking, misattribution, suggestibility, bias and persistence (Schacter, 1999).
But despite these ‘sins’, we still get by.
Memory is what makes us who we are.
Practically it enables us to function in everyday life.
Without it we would be lost, like those with severe amnesia who can’t remember who they are or achieve even the simplest of tasks.
So how can memory’s fallibility be reconciled with its abilities?
This series of posts explores these sins and in turn uncovers some bizarre stories as well as shedding light on everyday occurrences.
The surprise is that many sins of memory have a redeeming feature; sometimes the very sin itself is the flipside of one of memory’s saintly qualities, one we couldn’t do without.
Here are Schachter’s seven sins of memory:

The genetic treatment targets a matrix that helps ‘scaffold’ the brain’s nerve cells.
Are smartphones, computers and artificial intelligence making us stupid?
Most people’s earliest memories occurred years before they think, as confirmed by their parents.
When we try to recall something, we reach for the ‘gist’ of it first and then try to fill in the details.

The brain works in reverse to retrieve memories, research shows.
When we try to recall something, we reach for the gist of it first and then try to fill in the details.
This is the opposite to the way we lay down memories.
When we see an object, for example, it is the details — the colours and patterns — that we notice first.
It is only slightly later in the brain, that this shape registers as a ‘dog’ or a ‘spoon’.
Mr Juan Linde-Domingo, the study’s first author, said:
“We know that our memories are not exact replicas of the things we originally experienced.
Memory is a reconstructive process, biased by personal knowledge and world views—sometimes we even remember events that never actually happened.
But exactly how memories are reconstructed in the brain, step by step, is currently not well understood.”
For the study, people were shown unusual objects and asked to associate them with novel names.
Later, they had to remember and reconstruct the images they had seen as best they could.
Recordings of brain activity suggested the memory process runs in reverse when people are recalling an object, said Dr Maria Wimber, study co-author:
“We were able to show that the participants were retrieving higher-level, abstract information, such as whether they were thinking of an animal or an inanimate object, shortly after they heard the reminder word.
It was only later that they retrieved the specific details, for example whether they had been looking at a colour object, or a black and white outline.”
Mr Linde-Domingo said:
“If our memories prioritise conceptual information, this also has consequences for how our memories change when we repeatedly retrieve them.
It suggests they will become more abstract and gist-like with each retrieval.
Although our memories seem to appear in our ‘internal eye’ as vivid images, they are not simple snapshots from the past, but reconstructed and biased representations.”
The study was published in the journal Nature Communications (Linde-Domingo et al., 2019).
