My oh my, how ever did I miss this thread? Like Denise, this is a topic close to my heart, too! This is what I’ve gotten out of it since studying the subject…
According to TweedleWink, the purpose of early EK training is to populate the right brain with knowledge - kind of like filling a library with books. If done correctly (I’ll explain more about this later), when the children are older, the information will come back to them in a manner something akin to de javu - they may not remember how they know it or when they learned it only that they know it. I guess a good example would be like the one I read from Brain Rules for Baby by John Medina:
“It just jumped out at me!†Brott exclaimed to his mother. Brott had been at the podium of a symphony orchestra, conducting a piece of music for the first time, when the cellist began to play. He instantly knew he’d heard this piece before. This was no casual reminder of some similar but forgotten work: Brott could predict exactly what musical phrase was coming next. He could anticipate the flow of the entire work during the course of the rehearsal; he knew
how to conduct it even when he lost his place in the score.
Freaking out, he called his mother, a professional cellist. She asked for the name of the piece of music, then burst out laughing. It was the piece she had been rehearsing when she was pregnant with him. The cello was up against her late-pregnancy mid-abdomen, a structure filled with soundconducting fluids, fully capable of relaying musical information to her unborn son. His developing brain was sensitive enough to record the musical memories. “All the scores I knew by sight were the ones she had played while she was pregnant with meâ€, Brott later said in an interview. Incredible stuff for an organ not even zero years old.
I kind of get what he meant because when I was in Grade 5 on piano, my teacher made me learn a piece for an exam. The way my teacher used to teach me was to get me to sight read once through first. Ordinarily, my sight reading is crappy at best, but with this one particular piece, I played better than usual and it was a hard piece for me because the fingering was tricky. My teacher immediately asked me, “Have you played this before?” I had never played the piece before and I didn’t even remember ever having heard it before but something about it felt “familiar”. Did I listen to it when I was a child? I don’t know.
Another instance was a song I learned when I was very young. I read the lyrics again in a book when I was a teenager and I could hum the music for it even though the song was “new” to me. I only discovered that I’d learned the song as a child because my cousin later told me I used to sing it when I was little.
Even if a child cannot remember the information as clearly, learning it for the second time will very likely be easier than if they were hearing the information for the first time. For instance, I had to memorise the first 36 elements of the Periodic Table for Chemistry in Year 12. Even though I cannot recite them all now, I still remember the first ten and it will definitely be easier for me to memorise the other 26 elements if I had to learn it again now.
In this respect, I agree with Dr Paddy. If you are going to do EK, it makes more sense to cover material that will be relevant and useful to the child rather than obscure information they are unlikely to ever need.
However, based on information from Professor Makoto Shichida, EK is less about the information and more about stimulating the brain. Or perhaps he wasn’t really talking about EK, but he refers to the activity of rapidly flashing vast quantities of image flashcards to young children in order to stimulate their right brains and bring out its unique ability such as its photographic memory. In fact, someone on the forum (so sorry, I forget whom) posted a link to an article about some training involving rapid flashing in a darkened room being done with fighter pilots to help them learn to quickly distinguish between friendly and enemy planes. As a result of the training, some of them developed photographic memories. The article is here:

This information seems to be in concordance with Shichida’s speed flash card activity.
Going back to EK and developing encyclopedic knowledge… How do you ensure that the child retains the information and not forget it once they are older? This is the part I have not been quite clear on. I’ve read that you only have to flash the cards once and the child will remember (but for how long?), some say, at least four times, others say, not too many times or you will be stimulating the left brain which is not what you want. Based on what I understand about the child’s brain, I think TweedleWink’s method might be the way to go. In fact, this is what they do in Heguru as well. They recommend going through the flash cards with a child a few times, then putting them away for a while, say six months or a year, depending on the child, then bringing them out and flashing them again. The first exposure opens the child’s mind to the subject and the terminology. When the child receives the second exposure (6 months or 1 year later) he/she will have had more life experiences, greater knowledge and a better understanding of the world and new connections to the information will be formed. I guess this is pretty much what Tracy and Drummerboy are saying.
However, I feel it is important to have the repeat exposures to the flashcards at set intervals - 6 months, 1 year (exactly how frequently, I don’t know but as long as it is repeated over a period of time) - to avoid synaptic pruning. I first read about this in the Science of Parenting by Margot Sunderland but since then many others say the same thing - at birth, we have more brain cells than we will ever have in our lives, but there are very few connections between them. As that baby grows, numerous connections between the brain cells will be made forming a complex network. Once the child is about two years, synaptic pruning will begin - this is when the brain cuts off connections that are deemed redundant because of disuse. My take out from this is that if you don’t do repeat exposures to the information, synaptic pruning takes place and that’s why the children cannot remember the information they learned as infants and toddlers. How much of it gets erased depends on whether you are still covering related information. For instance, if you flashed famous artists for your child but never covered any other flash cards related to art, I think it’s a safe bet that your child will most likely have no memeory of those famous artists. If, however, you went on to flash famous works of those artists and other flash cards related to art, you can expect better retention of the information. I hope that makes sense.
So does EK make sense to me? Yes, I think so. But I think parents need to be very clear on what they are trying to achieve with it - brain exercise? Knowledge retention? Because I believe that it is done will affect the future results seen in the child.
