BBC Staff. (2004). “A coffee can make you forget.” BBC NEWS. Retrieved July 1st, 2010: http://news.bbc.co.uk/2/hi/health/3909085.stm SUMMARY: This article looks at the effects of caffeine found in coffee to the short-term memory. It proves that caffeine hinders ones ability to produce one-word answers but instead testers state that the answer is ‘on the tip of their tongues.’ To prove that caffeine does in fact affect ones short-term memory a study was conduction on two groups of 32 college students. One group was given 2oo mg of coffee, while the other was given a dummy drug. When the group with caffeine was asked to answer a question with a one-word answer they were less likely to answer correctly, while the ones without caffeine were successful. It was concluded from this study that caffeine does in fact keep one alert but unless a question is posed, pertaining to the users current train of thought it will be very difficult to produce a word. “It aids short-term memory when the information to be recalled is related to the current train of thought but hinders short-term memory when it is unrelated.” As a regular coffee drinker I found this article really interesting as I…

Response to “Is the Internet Making Us Quick but Shallow”

Carr, N. (2010). “Is the Internet Making Us Quick but Shallow,” CNN. Retrieved on 2010, June 29. http://www.cnn.com/2010/TECH/web/06/07/carr.internet.overload/index.html?hpt=C2 Nicholas Carr’s article, “Is the Internet Making Us Quick but Shallow,” demonstrates the negative consequences of the internet on the human mind. His article is in response to the media criticism President Obama received after stating that the internet and technological gadgets (i-pad, Blackberry, etc) ‘entertain,’ rather than ‘empower.’ While the media labeled Obama as anti-technology, the author defends and backups the president’s warning statement. Carr’s biggest criticism of the internet and screen gadgets is that they distract concentration, they hinder comprehension skills, and they weaken creative thought. The internet provides the user with an incredible amount of information and knowledge. However, the trouble lies within the manner in which that knowledge is transferred from the screen into the user’s brain. Links, for example, break and discombobulate information (the information is not provided in a linear and coherent format, such as found in a book) from one page of information to another, and thus causing the reader’s attention to rupture and drift. A case study done at Cornell University shows that laptops distract students in class and prevent them from absorbing information.…

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,…
