As we hit puberty, corresponding with a turbulent time of growth and learning in the rest of the body, there is another wave of synaptic proliferation in the brain. Then, as we move through adolescence, these connections are again pruned back and reorganised. Because our frontal and prefrontal cortex continue to develop in these ways during puberty and adolescence, we might expect to see a corresponding improvement in executive functions to do with memory which are associated with these frontal regions of our brain.
And indeed, this has been found to be the case: experiments have shown that our performance on complex working memory tasks continues to improve in adolescence, as does our prospective memory our ability to remember to do things in the future.

Memory in the teenage years While early childhood has long been recognised as an important time for brain development, it used to be thought that it was all over long before we hit puberty.

I didn't watch the news that day, but I know the in the newspapers — and especially the Sunday Mail ,which I read two days before — Kevin Rudd had Rebecca Sharrock: The 21st July was a Saturday, and that was a major event of my life personally, because it was the very last day that a book from the Harry Potter series was released.
It's when Harry Potter and the Deathly Hallows was released as a book. Rebecca Sharrock: That day…I didn't go to the shops myself, because due to my autism I couldn't deal because the shops were mayhem and everyone was rushing trying to get that book. So, my stepdad went and got us all a copy from Big W. So, when he came home, he brought in the book, and that's what I did for the rest of the day.
I just And it didn't take long as well because I have insomnia, because of the memories going through my mind, and my mind's always so busy and active and I can't sleep well at night because of it, but I found the if I could read Harry Potter, it would put me to sleep as a nine-year-old. So I thought to myself, I'm going to have to find a way where I can read Harry Potter but have my eyes closed. So I thought, I'll have to learn to recite the books, and that's when I taught myself — and I learnt in a rote-learning way — to learn different chapters of the books.
Donna Lu: That's incredible. So if I started reading some passages from different Harry Potter books Indeed by next morning Harry and Ron thought that meeting the three-headed dog had been an excellent adventure, and they were quite keen to have another one.
Donna Lu: That's amazing. Donna Lu: Yes it is. That is just incredible. How long did that take you to learn it all? Rebecca Sharrock: It depends. I'm now learning the new Harry Potter books — I'm learning to recite those as well.
I find to do three pages of a chapter…well, I call a page, you know, one side. So, technically that's six pages. But I find on average to do six regular book-sized pages, that takes me an hour. Rebecca Sharrock : Yeah. And I just I break it up too. I just remember a chunk of it, and it helps if I just have something — a ball in my hand — and just close my eyes, trying to remember.
If I'm distracted I can't do it, but if I'm just in silence with a ball, just a little stress ball or something, I can I find a can do it. Donna Lu: Incredible. Rebecca, how would you describe how your memory works? Rebecca Sharrock: Naturally, the memories come unprompted, or it seems unprompted because I'll just get a scent or I'll see something and subconsciously I'll relive a memory, but I can consciously make myself relive positive memories.
Negative too, but who wants to consciously relive negative memories. But I can consciously make myself relive positive memories, but the season has to match for it to work effectively, because there's no point trying to relive a sum of memory today.
Donna Lu: What kinds of memories do you have? Is it just, for example, is it conversations, or does it extend as well to physical things? Rebecca Sharrock: Just anything I've experienced through my five senses and also emotions, too.
So, any smell I get, any sight I see, also physical sensations, too. I can relive the pain of injuries and I can also relive pleasant tastes of food I like. Donna Lu: So, in thinking about a memory about a certain meal for example you can actually taste that meal again? Donna Lu: That's a pretty handy trick to have if you're eating something you don't really want to be.
Donna Lu: Do you link memories to specific dates consciously, or does it just happen? If I was too young, I still remember the day but I can't date it, as I didn't know about calendars then. It's opposite to recalling memories from dates.
It's more a case of recalling dates from memories. I know the earliest dated one, and I know the date because mum told me it was the day I was born. I remember just being held in a blanket and having something clipped to my ankle, and mum said that was the day I was born. There are memories of emotions before then and also just lying, you know, hunched up like this [hunches]. Rebecca Sharrock: Yeah. And I know whenever I feel stressed, because it was so comforting being in that position…I find I just grab myself like this [hunches in foetal position].
I've never mentioned that before. But it just reminds me of the sensation, just squeezing together like this. Donna Lu: It seems almost unbelievable that you can remember things from when you were very, very young, and I guess there's no way of verifying it. Do you have people ask you who are bit skeptical about those memories? What do you say to those people?
Now can you tell me the answer you gave two years ago? I can't even cheat and write down what I say without them knowing. So, that's something when I come across skeptics that does satisfy the most skeptical people somewhat at least. And another thing I do is that I'm drawing my memories that I saw as an infant, a child, a teenager, an adult.
I'm drawing my memories and that tends to interest a fair few people who were skeptical as well, just showing all the detail of what I saw at that age. But the one that tends to satisfy most is mentioning the video and how it's recorded and that then I 'm asked of it years later. Discover World-Changing Science. Get smart.
