Parents and teacher who were complaining about the concentration of children do not need to be worried anymore. After a research scientist have discovered that teenagers' brains continue developing far longer into adulthood than previously thought. Adolescents may look like young adults but their brain structure resembles that of much younger children. Dr Iroise Dumontheil of University College London's Institute of Cognitive Neuroscience claims that it is not the fault of the teenagers that they cannot concentrate on school, it is because of the brain structures. Using MRI scans, the brain activity of adolescents were monitored as they tried to solve a problem in their heads while ignoring environmental distractions. The scans revealed an unexpected level of activity in the prefrontal cortex, a large region at the front of the brain involved in decision-making and multitasking. This indicated that the brain was working less effectively than that of a gown up person. This means that the research has found out that there is too much going on in the brains of teenagers.
I think it is right that they have done research to find out how the brain of a teenagers works. ALthough, I am convinced that a lot of teenager who will read this news will use this as an excuse. I think that teenagers have a lot on their minds and that we could expect this results. Teenagers need time to develop themselves and their brain, this is why I think that people from 18 our 19 years cannot be seen as adults. They are still between being a teenager and an adult. Earlier research has point out that the age were people learn to the care of themself is when they are 23 years old. This is why I think that we should motivate young people to learn and to concentrate more, but we should not expect too much of them.

Haha this is quite interesting. I think it is good that they have done this research. But I am also afraid that students but also teachers will use it as an excuse and will be treated as small children. I mean it also depends on you motivation and the subjects that you like or dislike. And it is interesting to find out that we equally can learn just as much when we are older then as we are teenagers. So never give up. You should be motivated now as later in your older years.
BeantwoordenVerwijderenI always knew it wasn't my fault that I lacked concentration. I am surprised that it took untill know for scientists to discover. It has been a problem as long as children go to school, so I would have expected this reasearch to be done earlier. But nonetheless, it is still important for teachers to know. Maybe they can adept their lessons so they get more attractive, and maybe there are certain ways of dealing with this problem in a teacher's lessons.
BeantwoordenVerwijderenI think that teenagers are just going to use this as an excuse not to concentrate. I think that it isn't just up to teachers to make the lessons more interesting to keep students motivated but that students should be motived themselves even if the lessons are boring sometimes. I agree with Manon about not seeing 18 year olds as adults. I think there should be a period of transition between being a teenager and being an adult rather than to expect 18 year olds to carry the same level of responsibility as adults. I think the age for carrying that responsibility should be 19/20 so there is a transition.
BeantwoordenVerwijderenI also think that teenagers might use this news as excuse. It is probably true that this developing brain causes a lack of concentration, but I don’t think that’s all. I think you can also concentrate by motivating yourself to do that, you cannot just blame your brain developments for that.
BeantwoordenVerwijderenps. wow, many reactions on this topic!
