Exercise Your Brain, or Else You’ll … Uh

Article: Hafner, K. (2008). “Exercise Your Brain, or Else You’ll…Uh..” The New York Times. Retrieved 3 May, 2008. http://www.nytimes.com/2008/05/03/technology/03brain.html This article refers to our brain plasticity and interferences that can occur in our long term and working memories. Plasticity, or neuroplasticity, is the lifelong ability of the brain to reorganize neural pathways based on new experiences, in other words, the ability of the brain to change with learning (Hoiland, 2008). According to the article, our brains contain more plasticity than originally thought. The argument is that if we do not exercise our brains, the lack of their use can lead to interferences in long term or working memories. For example: forgetting a good friends name or even our address. – According to Werby the working memory can be defined as, the thinking space [of the brain]- writing requires the author to keep in mind and monitor words spelling, rules of composition etc. The long term memory is defined as, the vast storage of information that we accumulate throughout our lives, and it includes data, procedures, algorithms, and anything else we can think of. This is the type of memory we usually speak of when we refer to our memory (Werby,…

Mobile phones expose human habits.

Article: Fildes, J. (2008). “Mobile phones expose human habits.” BBC News. Retrieved 4 June, 2008. http://news.bbc.co.uk/go/pr/fr/-/2/hi/science/nature/7433128.stm Summary: As the title suggests this article concerns the discovery of human mobility habits via the use of mobile phones. In other words over 100, 000 mobile phones were tracked in an attempt to build a comprehensive picture of human movements. The study showed, that humans are creatures of habit, mostly visiting the same few spots time and time again, and that most people move less than 10km on regular basis. The study is seen as important as it can help when assessing the situation during a viral outbreak such as the Avian Flu and in the forecasting of traffic. Previously similar studies had been performed with GPS which proved to expensive, surveys which proved unreliable and dollar bills. Dollar bills were tracked in order to reconstruct human movements however this seemed only to prove random patterns and did not give a complete picture of people s movements. The phone tracking worked differently. Each time a participant made or received a call or text message, the location of the mobile base station relaying the data was recorded. The results showed that people moved around…
