You can increase your intelligence:

5 ways to maximize your cognitive potential

By Andrea Kuszewski | March 7, 2011

One should not pursue goals that are easily achieved. One must develop an instinct for what one can just barely achieve through one’s greatest efforts.” —Albert Einstein

Andrea Kuszewski have come up with five primary elements involved in increasing your fluid intelligence, or cognitive ability. Read more…

Your brain dominance and language learning

Your brain dominance and language learning

Introduction

Some language skills involve analytical, sequential, and left-brain processing. Others involve right-brain skills such as guessing, associating, and getting the main idea.

Obviously, those with bilateral dominance have some advantages.

There are, however, good language learners with both left-brain or right-brain dominance who achieve a high degree of fluency and accuracy. They learn to use both left-brain and right-brain skills depending on what works best for the activity at hand. Read more…

Hearing Bilingual: How Babies Sort Out Language

Researchers found that at 6 months, the monolingual infants could discriminate between phonetic sounds, whether they were uttered in the language they were used to hearing or in another language not spoken in their homes. By 10 to 12 months, however, monolingual babies were no longer detecting sounds in the second language, only in the language they usually heard.

This represents a process of “neural commitment,” in which the infant brain wires itself to understand one language and its sounds.

In contrast, the bilingual infants followed a different developmental trajectory. At 6 to 9 months, they did not detect differences in phonetic sounds in either language, but when they were older — 10 to 12 months — they were able to discriminate sounds in both.

Bilingual children also develop crucial skills in addition to their double vocabularies, learning different ways to solve logic problems or to handle multitasking, skills that are often considered part of the brain’s so-called executive function.

Sleep Your Way to An ‘A’

February 19th, 2011 No comments

我们都知道,充足的睡眠有利记忆。可是为什么我们学的东西有的记住了,但很多都忘记了?特别是老师在突然袭击考试的时候,脑子一片空白,什么都想不起来了呢?德国吕贝克大学(University of Lübeck)的科学家詹•伯恩(Jan Born)和他的同事最近在《神经科学杂志》上发表的一篇论文中说:只有当我们知道,学的东西是有用的,比如老师马上要考这些内容时,睡眠才会有选择地帮助我们把白天学到的东西从短期记忆转换成长期记忆。如果我们只是学着玩儿,那睡不睡觉对记忆都没什么影响。难怪考试是老师的法宝,看来是有科学依据的;)

下面是Newsweek 2011年2月13日刊登的文章:“Sleep Your Way to An ‘A’

Getting a good night’s sleep has long been known to cement the day’s memories, moving them from short-term storage into long-term holding, but new research shows that it’s not automatic. A night of z’s is helpful only if you know a test is coming or, more generally, if you explicitly tell yourself you’ll need the information in the future. In other words, don’t expect eight hours of shut-eye to help you on a pop quiz.

The new research is the first to show how sleep works its memory magic. EEGs found that the “test is coming” group spent more time in deep, slow-wave sleep than did the group not anticipating a test. Slow electrical waves act as a replay button, causing the hippocampus to reactivate new memories and synchronizing the neocortex so that it accepts them into long-term storage. This expectant group also had more “sleep spindles,” bursts of electrical activity that prime networks in the cortex to store memories arriving from the hippocampus and to integrate them into existing knowledge, which makes retrieval easier.

Psychology Today also published a blog post on this topic by Faith Brynie, a scientific and medical writer.

CNN:Why right-brainers will rule this century

October 17th, 2010 No comments

Pink, a former chief speechwriter for former Vice President Al Gore, presents a convincing argument that the world is entering a new era — the so-called conceptual age — during which right-brained skills such as design and storytelling will become far more crucial than traditionally left-brained skills such as accounting and computer programming.

Your left brain is logical, linear, by-the-numbers; the right side is creative, artistic, empathetic. Oprah Winfrey talks with Daniel Pink about his groundbreaking book, “A Whole New Mind”, and explores how right-brain thinkers are wired for 21st-century success.

The best part: Anyone can tap into the right mind-set.
