How reading shapes your brain

Introduction Do you remember what it was like before you learnt to read? It's hard to think back that far! Scientific research has shown that learning to read changes the way our brains work. Not only that, but depending on the language you are reading, your brain changes in different ways. Becca and Georgie discuss this and teach you some new vocabulary. This week's question The longest novel in the world is widely thought to be by French author Marcel Proust. Its title has been translated into English as Remembrance of Things Past, and more recently as In Search of Lost Time. But how many words does the book contain? a) 130,000 b) 1.3 million c) 13 million Listen to the programme to hear the answer.

Welcome to 6 Minute English from BBC Learning English. I'm Becca.   Georgie And I'm Georgie. Remember, you can find all this episode's vocabulary along with a transcript and worksheet on our website, bbclearningenglish.com.  Georgie Now, Becca, do you read a lot? Becca Hmm, I don't read often. I just feel like I don't have the time, Georgie. How about yourself?   Georgie I would love to read more, but I don't read very much at the moment. I read mostly before bed because I feel like it helps me relax and go to sleep. And today we're talking all about reading. We'll be hearing from some experts about how reading can change our brains, and as usual we'll be learning some useful new words and phrases.   Becca Let's start with a quiz question. The longest novel in the world is widely thought to be by French author Marcel Proust, a book which, when translated into English, means Remembrance of Things Past. But how many words does the book contain? Is it:   a)    130,000, b)    1.3 million, or c)    13 million?   Georgie OK. The longest novel in the world. I still think 13 million words sounds too many, so I'm going to go with b) 1.3 million. Becca Alright. We'll find out at the end of the programme. Now, we might think of reading as like speaking. We're born with the potential to do it and then we learn. It's natural. If something is natural, it's something you were born with or that comes from nature.   Georgie But Maryanne Wolf, author of the book Reader Come Home, says that this isn't true.   Maryanne Wolf We think of language as natural, and reading is written language so it must be natural. But it isn't. It isn't natural at all.   Becca Scientific studies suggest that when we're born, our brains already have the networks that allow our eyes to see and our vocal cords to produce sounds, but not with the pathways we need to read.   Georgie Let's hear more from psychologist and neuroscientist Rebecca Gotlieb, speaking to the BBC World Service.   Rebecca Gotlieb From an evolutionary timescale, our brain hasn't had enough time to develop a dedicated reading brain. And so, to build a reading brain network, we co-opt parts of the brain involved in vision and auditory processing, and language, and attention and affect. Reading is really a whole brain process. It involves activation in all four lobes of the cortex. The process of developing a reading brain alters everything, from brain activity to brain structure and brain connectivity. The power of deep reading is really fundamental to our humanity. When we read deeply, we change our brains and we change who we are.   Becca Rebecca says that our brains haven't evolved to include a dedicated reading brain. Dedicated here means designed and used for one particular purpose.   Georgie So, because we don't have a part of the brain designed specifically for reading, when we learn to read, we co-opt other parts of the brain. Co-opt here means to include someone or something, often against their will. Becca Right. Learning to read means using lots of different parts of the brain that are designed for other things, and this changes our brain structure compared to someone who hasn't learned to read.   Georgie And the language we read also shapes our brain. Chinese characters, for example, use symbols instead of letters of the alphabet to represent words and ideas.   Becca Research suggests that learning to read these symbols activates different areas of the brain to reading an alphabet-based system.   Georgie Scientists studied a bilingual man who could read and speak Chinese and English. The man suffered a stroke, which affected parts of his brain, including his ability to read Chinese. But amazingly, he was still able to read English.   Becca Maryanne Wolf explains more to the BBC World Service.   Maryanne Wolf It's a beautiful example of how the brain's circuit reflects the requirements of Chinese, which inevitably means more visual memory and visual processing of those beautifully intricate symbols or characters.   Georgie Maryanne says that the brain's circuit is shaped by learning to read Chinese. A circuit is a system of connections.   Becca The visual qualities of Chinese symbols inevitably mean more visual areas of the brain are developed. Inevitably means in a way that cannot be stopped or avoided.   Georgie Maryanne describes the symbolic Chinese characters as beautifully intricate. If something is intricate, it has lots of detail. Becca And something which also has lots of detail, or certainly lots of words – I asked you, Georgie, how many words are in Marcel Proust's Remembrance of Things Past.   Georgie I said 1.3 million.   Becca And you were correct!   Georgie Yay!   Becca The book also contains lots of very long sentences, including one with over 900 words.   Georgie One sentence with 900 words? That is a lot. OK. It's time to recap the language we learned during this programme, starting with natural, which describes something you were born with or that comes from nature.   Becca Dedicated can describe something that is designed and used for one particular purpose.   Georgie If you co-opt someone or something, you involve them, sometimes against their will.   Becca A circuit is a system of connections – for example, in the brain.   Georgie Inevitably means in a way that cannot be stopped or avoided.   Becca And intricate describes something which has lots of detail.   Georgie That's it for this episode of 6 Minute English.
