It can be a powerful tool. Experiments have shown that if you are sent into a virtual-reality environment with a particularly good-looking “avatar,” or digital self-image, you are likely to become more sociable. Seeing your avatar exercising in a virtual world can spur you to add an hour a day to your exercise routine in the real world; people whose avatars do the dirty work of sawing down a virtual tree use less real paper later in the day. Given a taller avatar, you will act more confident and negotiate more selfishly.
How does the Proteus effect make people more willing to save? “Imagine that you just got a horrible haircut or bought a great new suit,” says Jeremy Bailenson, a virtual-reality researcher who runs the Stanford lab. “You already know that your physical appearance affects your attitudes, your emotions and your behavior even if you’re not consciously thinking about it. The same thing happens in virtual reality, when you become this person with a different body or face. Those features of your avatar affect your mind.”
Although the data from those early studies showed dismal results, I wasn’t discouraged. I still believed it was possible to significantly increase your cognitive functioning, given the proper training—since I had seen it with my own eyes through my work as a therapist.
Then in 2008, a very exciting study was published, Improving Fluid Intelligence with Training on Working Memory, by Jaeggi, Buschkuehl, Jonides, and Perrig. This study was pretty much a game-changer for those doing research on this topic. They showed for the first time, that it might actually be possible to increase your intelligence to a significant degree through training. What did they do different?
The subjects in Jaeggi’s study were trained on an intensive, multimodal (visual and auditory input) working memory task (the dual-n-back) [1] for variable lengths of time, for either one or two weeks, depending on the group. Following this training, they were tested to see how much they improved. As one would expect, after training, their scores on that task got better. But they went a step further. They wanted to see if those gains on the training task could transfer to an increase in skill on a completely different test of cognitive ability, which would indicate an increase in overall cognitive ability. What did they find?
Following training of working memory using the dual n-back test, the subjects were indeed able to transfer those gains to a significant improvement in their score on a completely unrelated cognitive task
Teaching Problem Solving
28-Mar-11
A technique is available, however, which provides prob1em-solving practice for an entire class. It is called Thinking Aloud Pairs Problem Solving (TAPPS). This method evidently was first explored by Claparede (described in Woodworth, [10]), and was later used by Bloom and Broder [2] in their study of the problem-solving processes of college students. Art Whimbey and Jack Lochhead [6, 7] have further expanded the technique in their attempts to improve the teaching of reading, mathematics, and physics. In the method a class is divided into a number of teams, each team consisting of two students, with one student being the Problem Solver (PS) and the other being the Listener (L). Each member of the team has a definite role to play, and both must adhere strictly to some rules.
In an article Lochhead [4] has elaborated some of these rules. PS reads the problem aloud and then continues to talk aloud as much as possible about everything he/she is thinking while attempting to solve the problem. L listens, and has the more difficult role. L must try to keep PS talking; a short silence should be met with, “Tell me what you’re thinking.” More, L must understand in detail every step made by PS. Thus L should ask questions whenever PS says anything that is in the least mysterious. “Why do you say that?” “I don’t understand. Would you explain that to me?” “Run that by again.” are some of the questions/comments L may use. L must avoid solving the problem herself, and must not ask questions which are actually intended as hints to PS. In fact, it isn’t necessary that L be able to solve the problem; her role is to help PS solve it. When students are first learning the method L perhaps can point out that PS has made an error, but should not tell him where it is. With more advanced students it is probably better to let PS find the error on his own. PS and L should switch roles after every problem, but they should never change roles within a problem.
How To Have A Rational Discussion
28-Mar-11
Science has finally confirmed what anyone who’s ever been in love already knows: Heartbreak really does hurt.
In a new study using functional magnetic resonance imaging (fMRI), researchers have found that the same brain networks that are activated when you’re burned by hot coffee also light up when you think about a lover who has spurned you.
In other words, the brain doesn’t appear to firmly distinguish between physical pain and intense emotional pain. Heartache and painful breakups are “more than just metaphors,” says Ethan Kross, Ph.D., the lead researcher and an assistant professor of psychology at the University of Michigan, in Ann Arbor.
The study, which was published in the journal Proceedings of the National Academy of Sciences, illuminates the role that feelings of rejection and other emotional trauma can play in the development of chronic pain disorders such as fibromyalgia, Kross says. And, he adds, it raises interesting questions about whether treating physical pain can help to relieve emotional pain, and vice versa.

Intermittent fasting preserves lean mass
25-Mar-11
Dietary restriction is an effective strategy for weight loss in obese individuals. The most common form of dietary restriction implemented is daily calorie restriction (CR), which involves reducing energy by 15-60% of usual caloric intake every day. Another form of dietary restriction employed is intermittent CR, which involves 24 h of ad libitum food consumption alternated with 24 h of complete or partial food restriction. Although both diets are effective for weight loss, it remains unknown whether one of these interventions produces superior changes in body weight and body composition when compared to the other. Accordingly, this review examines the effects of daily CR versus intermittent CR on weight loss, fat mass loss and lean mass retention in overweight and obese adults. Results reveal similar weight loss and fat mass loss with 3 to 12 weeks’ intermittent CR (4-8%, 11-16%, respectively) and daily CR (5-8%, 10-20%, respectively). In contrast, less fat free mass was lost in response to intermittent CR versus daily CR. These findings suggest that these diets are equally as effective in decreasing body weight and fat mass, although intermittent CR may be more effective for the retention of lean mass.
“Overall, body attractiveness was a better predictor of self-reported mating success than facial attractiveness. In line with our main hypothesis, we found a positive relationship between a composite measure of men’s physical fitness (PF) and men’s body attractiveness. This was obtained not only for aggregated attractiveness ratings but also for all 27 female raters individually. This finding is remarkable because individual attractiveness judgments reflect a strong idiosyncratic component, at least for faces. Attractiveness judgments were made fast and effortless. The strength of the attractiveness-fitness relation- ship obtained here suggests that signalling physical fitness may be one of the key functions of male attractiveness.”
