Many people, particularly as they get older, have concerns about short-term memory problems: going to another room to do something and then forgetting why you’re there; deciding to do something, becoming distracted by another task, and then forgetting the original intention; uncertainty about whether you have just performed a routine task; forgetting things you’ve said or done seconds after having said or done them; thinking of something you want to say during a conversation, then forgetting what it was by the time it’s your turn to speak, and so on.

The Proto-Indo-European language (PIE) is the ultimate ancestor of many European and Indian languages. The word "proto" indicates it was spoken thousands of years in the past and we have no direct record of it. What we do have is the clear evidence in its descendant languages, from the consistent patterns in the way their words vary, that there was such an ancestor. Following these patterns, scholars have deduced a quite extensive vocabulary — but they are still reconstructed, not ‘real’ words. We can never know exactly how these words were pronounced, or precisely how they were used.
This is the last part in my series on understanding scientific text. In this part, as promised, I am going to talk about the difficulties novices have with scientific texts; what they or their teachers can do about it; and the problems with introductory textbooks.
Children learn. It’s what they do. And they build themselves over the years from wide-eyed baby to a person that walks and talks and can maybe fix your computer, so it’s no wonder that we have this idea that learning comes so much more easily to them than it does to us. But is it true?
There are two particular areas where children are said to excel: learning language, and learning skills.
A perennial topic in the arena of memory improvement is the question of “food for the brain”, and in particular, whether there are dietary supplements that can improve your mental abilities. While my own emphasis is improvement through development and practice of skills, I don’t dismiss the possibility of improvement through more physical means. I myself am a great fan of the “you are what you eat” principle. This is mainly because I suffer from multiple food sensitivities, so the consequences of food are very much a reality for me.
Back in 2010, I read a charming article in the New York Times about a bunch of neuroscientists bravely disentangling themselves from their technology (email, cellphones, laptops, …) and going into the wilderness (rafting down the San Juan River) in order to get a better understanding of how heavy use of digital technology might change the way we think, and whether we can reverse the problem by immersing ourselves in nature.
Here’s an interesting study that’s just been reported: 72 seven- and eight-month-old infants watched video animations of familiar fun items being revealed from behind a set of colorful boxes (see the 3-minute YouTube video).
Compulsory Education: When it starts and how long it lasts
Around the world, for the most part, compulsory schooling starts at 6, although some start at 7, and a very few at 5 or even younger. There is less consensus about how long compulsory education should last, but 9 years is the most common length, with 10 years running a close second.
The more hyped and less plausible passive Mozart Effect
The so-called "Mozart effect" refers to two quite different phenomena. The one that has received the most media play concerns the almost magical (and mythical) effect of Mozart's music on intelligence. It is the result of a misrepresentation of the research results. Rauscher, Shaw, and Ky's 1993 study found that 10 minutes of exposure to Mozart's Sonata for Two Pianos in D Major K. 448 temporarily enhanced performance on three spatial reasoning tasks.
