Language-learning expertise

Landau, E. (2010). “From brain to language to accent.”  CNN Online. Retrieved on October 4, 2010: http://pagingdrgupta.blogs.cnn.com/2010/09/23/from-brain-to-language-to-accent/?hpt=Sbin Becoming a proficient speaker of at least one language is a hallmark of the typical human psychological development. When it comes to learning more than one language, however, our abilities seem much more widely dispersed. Why might some people display a greater “talent” for learning a second language (or more) than others? By far the best known predictor of success at foreign language learning is the learner’s age.  An increasing number of children who grow up in bilingual environments from early on may well grow up to be fluent speakers of both their native languages. But you don’t have to be natively bilingual in order to master multiple languages at the native-speaker level. In a classic study of second-language acquisition by Johnson & Newport (1989), immigrants to the USA were tested for high-level mastery of English (including phonetic and grammatical nuances), and the results were examined as a function of age at initial immersion in the English-speaking environment. People who started learning English before the age of 7 tended to achieve native-like proficiency. From there on, the older one was at arrival, the less native…

Dating by blood type in Japan

Buerk, R. (2010). “Dating by blood type in Japan.” BBC News. Retrieved on 3 October, 2010: http://news.bbc.co.uk/2/hi/8646236.stm People in most parts of the world do not think about their blood group much, unless they have an operation or an accident and need a transfusion. But in Japan, whether someone is A, B, O or AB is a topic of everyday conversation. There is a widespread belief that blood type determines personality, with implications for life, work and love. Interest in blood type is widespread in Japan, particularly which combinations are best for romance. Women’s magazines run scores of articles on the subject, which has also inspired best-selling self-help books. There are employers who are discriminating against prospective candidates by asking about their blood type. A term for such behavior in Japan is burahara, which translates as blood group harassment. The preoccupation with blood ultimately dates back to theories of eugenics during the inter-war years. Stripped of its racial overtones, the idea emerged again in the 1970s. Now, blood typecasting is as common as horoscopes in the West, with the whiff of science—although dubious—giving it added credibility. Scientists regularly debunk the blood group theory but it retains its hold—some believe because,…

Sizing Up Consciousness by Its Bits

Zimmer, C., (2010). “Sizing Up Consciousness by Its Bits.” NYTimes.com. Visited on October 3, 2010: http://www.nytimes.com/2010/09/21/science/21consciousness.html Carl Zimmer’s article “Sizing Up Consciousness by Its Bits” for The New York Times seeks to introduce and explore a relatively new area of research into human consciousness. In interviews with the medical researcher Dr. Giulio Tononi, the article discusses current and past conceptions of consciousness and its’ implications for our interactions with each other and with our environment. Given the importance of consciousness in everyday human life, one would reasonably assume that at this time science would have a detailed understanding of consciousness and how it functions. This is not the case, however. Despite centuries of philosophical debate, medical research, and technological development, humans are largely in the dark, so to speak, about what creates and maintains the spark of consciousness. In the context of our currently vague understanding, Dr. Tononi’s research proposes a novel way of conceptualizing consciousness. Dr. Tononi’s goal is to apply the theories of informational networks to the human brain, in a method he terms “Integrated Information Theory.” This theory, hereafter referred to as IIT, seeks to understand the human brain as an integrated network of nodes (neurons in…

More is always better – Or so most think!

Tugend, A., (2010). “For the Dishwasher’s Sake, Go Easy on the Detergent.” NY Times Online. Visited on November 04, 2010: http://www.nytimes.com/2010/03/13/your-money/13shortcuts.html   If dishwashers do not seem to be doing their job or if your clothes are not coming out as soft as you’d like them to, or if these machines break down easily, it is most likely due to “user error.” We throw in multiple fabric softener sheets because more is better. More isn’t better in this case! The excess sheets liquefy when the dryer gets hot and gum up the dryer. Most people use ten to fifteen times the amount of soap they need. This excess soap is detrimental to the life of the machines.   This article has some clear implications for interaction and interface design.  User errors are likely to happen. Even if you have a manual with detailed instructions, the chances of somebody reading that manual are very slim. Even if they read it, they are still likely to err. How can design inculcate the right usage in the user? In this case, what can design do to prevent errors resulting from the ‘More is better’ p-prim?    Possible Interaction Design Solutions: Solutions could be…

Intention over Outcome

BBC Staff, (2010). “Morality is modified in the lab.” BBC Online. Visited on October 02, 2010: http://news.bbc.co.uk/2/hi/health/8593748.stm. This article highlights a study that proves that human moral judgment can be modified by disrupting a specific area of the brain by applying magnetic pulses. For example, most of us would agree that it is morally unacceptable for a man to let his girlfriend walk across a bridge he knew to be unsafe. If he did not know it was unsafe, and the girlfriend did not make it safely across the bridge, we would not hold the man responsible for letting her cross the bridge. After a magnetic pulse is applied to a certain area of our brains we would think differently—Whether or not the man knew it to be unsafe, we would think it was morally acceptable for the man to let his girlfriend cross the bridge if she made it safely across. If she didn’t, we would feel it was morally unacceptable, regardless of whether or not he knew it to be unsafe. This shows how the judgment can be influenced to become outcome based rather than intention based. On Concept: If the reverse were possible, that is morally questionable…

Re “Forget What You Know About Good Study Habits”

Carey, B. (2010). “Forget What You Know About Good Study Habits.” New York Times Online. Retrieved on 26 October, 2010: http://www.nytimes.com/2010/09/07/health/views/07mind.html The main topic of this article is to dispel a few beliefs about effective study habits. According to this article, research has clearly demonstrated that we don’t have credible evidence for the utility of popular learning-style approaches that we follow. The article also outlines a few simple techniques that can reliably improve how much we learn from studying. Personally, I wish I read this article when I was a full time student as it might have helped me to be a better learner. Conceptual Design: With each of us having specific learning styles, a designer for a learning product can build a system that adopts to our learning styles. For example a system can test its users and determine their learning style and focus on a approach that might make the user learn faster and better. If the learning is tough, learners (Students) might lose interest and motivation. So effective approaches of learning such as variability in setting and materials must be used to improve learnability and retention.  Such design approaches would make learning easy and engage the users…

On “Keeping Kids Safe From the Wrong Dangers” by Belkin

Belkin, L. (2010). “Keeping Kids Safe From the Wrong Dangers” New York Times Online. Retrieved on October 6, 2010: http://www.nytimes.com/2010/09/19/weekinreview/19belkin.html?_r=1 Summary: Belkin puts the spotlight on the somewhat irrational behaviors of parents when it comes to protecting their children. With the best of intentions, they worry about kidnapping, school snipers, terrorist, dangerous strangers and drugs, while the most likely things to cause children harm are car accidents, homicide (usually at the hands of someone they know), child abuse, suicide and drowning. So why are parents constantly overestimating rare dangers while underestimating common ones? The author makes the point that evolution may have something to do with it in that our brains are not designed to process abstract or long-term risk, but rather to react to an immediate dangers for instance represented by a sound and make a determination of whether not it presents a danger. In today’s fast-paced world where we are bombarded with all kinds of worst case scenarios and sensationalism, our sense of proportions gets distorted. So, we end up driving our kids to play-dates, when a walk on their own may have been better both health and safety wise. User Groups: So how can parents make more…
