Thinking in a Foreign Language Makes Decisions More Rational
To judge a risk more clearly, it may help to consider it in a foreign language.
A series of experiments on more than 300 people from the U.S. and
Korea found that thinking in a second language reduced deep-seated,
misleading biases that unduly influence how risks and benefits are
perceived.
“Would you make the same decisions in a foreign language as you would
in your native tongue?” asked psychologists led by Boaz Keysar of the
University of Chicago in an April 18 Psychological Science study.
“It may be intuitive that people would make the same choices
regardless of the language they are using, or that the difficulty of
using a foreign language would make decisions less systematic. We
discovered, however, that the opposite is true: Using a foreign language
reduces decision-making biases,” wrote Keysar’s team.
Psychologists say human reasoning is shaped by two distinct modes of thought: one that’s systematic, analytical and cognition-intensive, and another that’s fast, unconscious and emotionally charged.
'Would you make the same decisions in a foreign language?'
In light of this, it’s plausible that the cognitive demands
of thinking in a non-native, non-automatic language would leave people
with little leftover mental horsepower, ultimately increasing their
reliance on quick-and-dirty cogitation.
Equally plausible, however, is that communicating in a learned language forces people to be deliberate,
reducing the role of potentially unreliable instinct. Research also
shows that immediate emotional reactions to emotively charged words are muted in non-native languages, further hinting at deliberation.
To investigate these possibilities, Keysar’s team developed several
tests based on scenarios originally proposed by psychologist Daniel
Kahneman, who in 2002 won a Nobel Prize in economics for his work on prospect theory, which describes how people intuitively perceive risk.
In one famous example, Kahneman showed that, given the hypothetical
option of saving 200 out of 600 lives, or taking a chance that would
either save all 600 lives or none at all, people prefer to save the 200 —
yet when the problem is framed in terms of losing lives, many more people prefer the all-or-nothing chance rather than accept a guaranteed loss of 400 lives.
People are, in a nutshell, instinctively risk-averse when considering gain and risk-taking when faced with loss,
even when the essential decision is the same. It’s a gut-level human
predisposition, and if second-language thinking made people think less
systematically, Keysar’s team supposed the tendency would be magnified.
Conversely, if second-language thinking promoted deliberation, the
tendency would be diminished.
The first experiment involved 121 American students who learned
Japanese as a second language. Some were presented in English with a
hypothetical choice: To fight a disease that would kill 600,000 people,
doctors could either develop a medicine that saved 200,000 lives, or a
medicine with a 33.3 percent chance of saving 600,000 lives and a 66.6
percent chance of saving no lives at all.
Nearly 80 percent of the students chose the safe option. When the
problem was framed in terms of losing rather than saving lives, the
safe-option number dropped to 47 percent. When considering the same
situation in Japanese, however, the safe-option number hovered around 40
percent, regardless of how choices were framed. The role of instinct
appeared reduced.
Two subsequent experiments in which the hypothetical situation
involved job loss rather than death, administered to 144 native Korean
speakers from Korea’s Chung Nam National University and 103 English
speakers studying abroad in Paris, found the same pattern of enhanced
deliberation. “Using a foreign language diminishes the framing effect,”
wrote Keysar’s team.
The researchers next tested how language affected decisions on
matters of direct personal import. According to prospect theory, the
possibility of small losses outweigh the promise of larger gains, a
phenomenon called myopic risk aversion and rooted in emotional reactions to the idea of loss.
The same group of Korean students was presented with a series of
hypothetical low-loss, high-gain bets. When offered bets in Korean, just
57 percent took them. When offered in English, that number rose to 67
percent, again suggesting heightened deliberation in a second language.
To see if the effect held up in real-world betting, Keysar’s team
recruited 54 University of Chicago students who spoke Spanish as a
second language. Each received $15 in $1 bills, each of which could be
kept or bet on a coin toss. If they lost a toss, they’d lose the dollar,
but winning returned the dollar and another $1.50 — a proposition that,
over multiple bets, would likely be profitable.
When the proceedings were conducted in English, just 54 percent of
students took the bets, a number that rose to 71 percent when betting in
Spanish. “They take more bets in a foreign language because they expect
to gain in the long run, and are less affected by the typically
exaggerated aversion to losses,” wrote Keysar and colleagues.
The researchers believe a second language provides a useful cognitive
distance from automatic processes, promoting analytical thought and
reducing unthinking, emotional reaction.
“Given that more and more people use a foreign language on a daily
basis, our discovery could have far-reaching implications,” they wrote,
suggesting that people who speak a second language might use it when
considering financial decisions. “Over a long time horizon, this might
very well be beneficial.”

Benefits of Reading
Benefits of Reading
With the popularity of computers and video games in recent times,
habit of reading has taken a backseat. Most parents and children are so
occupied in watching movies, television and addicted to computer games
that they find little or no time for reading. However those who have
developed reading as a hobby are aware of the countless advantages
associated with it. Reading broadens the thinking horizon of a person,
improves vocabulary and cultivates sensitivity towards people of
different cultures.
Benefits associated with reading
1.Exercises your mind.
Reading bends loosens and supple the mind. It helps in keeping the muscles of the brain in good shape.
2.Gives satisfaction
Reading gives immense satisfaction to a person. Nothing can be more satisfying than to sit with your child and read him a story book, or to see him grow with the fairy tales.
3.Expands the imagination
Reading expands the imagination of a person. One becomes more confident, self assured of his ability to understand and appreciate the various aspects of life. The mind is channelized to think about the different aspects and then questions and derives conclusions about them.
4.Enhances the ability to focus
The mind of a reader is more concentrated and focused about various aspects of life. When the mind is focused it has the capability to be more attentive in practical situations of life. As a result the body and mind of such people remain calm; they look at the problem objectively and are better decision makers.
5.Improves knowledge
Reading improves a person’s knowledge about various fields of life. This
knowledge base helps a person to make correct decisions in different
situations of life.
6.Helps to achieve goals in life
People who develop reading habit since childhood are better able to decide their goals in life. Reading also helps them in achieving these goals because once a person gets in love with books it is easier for him to just switch over from general reading to their course books.
7.Produces efficient orators
Only those who know something of quality can speak and gains respect and recognition from people. People with scarce knowledge about a subject cannot be good orators.
8.Teaches the art of living
Reading biographies of legendary individuals help the reader to learn the art of living.
9.Helps to accept other cultures and religions.
Just having information about other cultures might create misconceptions about their traditions and mythologies. A thorough reading gives clarity about the fundamentals of other religions. This helps the person to accept them in a better and overwhelming manner.
So instead of killing long hours watching television and playing
games on computer spend some time in reading so that you not only
refresh you mind but also develop a good hobby which you will later on
transfer to your children.

Powerful Lengevity Foods (Food Matters)
The more we learn, the clearer it is that longevity isn't just about our
genetic heritage. Instead we can control many of the factors that will
influence the quality and quantity of our years with all those small,
daily decisions we make about nutrition, fitness, sleep and other health
behaviors.
So when we saw the recent study linking vitamin D and calcium supplements to a longer lifespan, it got us thinking. What other nutrients or foods could help improve lifespan? Read on for some tasty items that may just add years to your life.
So when we saw the recent study linking vitamin D and calcium supplements to a longer lifespan, it got us thinking. What other nutrients or foods could help improve lifespan? Read on for some tasty items that may just add years to your life.
Broccoli For Cancer Protection
Broccoli and other cruciferous vegetables are full of sulforaphane and
other antioxidants that help to protect healthy cells from damage caused
by free radicals. But when it comes to the veggies, raw may be better:
recent research has found that boiling in water has a "leaching effect."
Whole Grains For Cardiovascular Health
Whole grains offer a variety of antioxidants and vitamins, and are
packed with fiber, known to help protect against high cholesterol and
regulate blood sugar levels, which can safeguard against diabetes. For
those with gluten sensitivities its important to steer clear of gluten
containing grains like wheat, barley and rye and opt for buckwheat and
rice in its whole form.
Berries For Brain, Bone And Brawn
Not only are berries good for extending life -- they improve the quality
of later years. Berries are chock full of antioxidants that help
protect against free radical damage, but as Whole Livingreported, one
antioxidant in particular -- anthocyanins -- is particularly useful for
brain function, balance and muscle retention.
Dark Chocolate For Anti-Inflammation
Dark chocolate is full of inflammation-reducing flavonoids, a compound
that also has antioxidant properties and helps prevent blood clots. But
reducing inflammation is its real longevity trick, as research shows
that molecular inflammation may be responsible for much aging and cell
death.
Tomatoes For Cancer Prevention
Tomatoes are a great source of lycopene, the fat-soluble nutrient that
helps to protect against some types of cancer, like prostate, lung and
stomach cancers.
Beets For Betaine Power
Beets are rich in betaine, a compound associated with lower markers of
inflammation, according to the latest research in the American Journal
of Clinical Nutrition.
Walnuts For Lower Cholesterol
Walnuts are a great source of alpha linolenic acid (ALA), which is a
type of omega-3 fatty acidassociated with reduced inflammation.

52. Upon what do these various effects depend?
Upon the mechanism to which electricity is attached.
53. What is the result of the action and interaction of the individual mind upon the Universal?
The conditions and experiences with which we meet.
54. How may these conditions be changed?
By changing the mechanism by which the Universal is differentiated in form.
55. What is this mechanism?
The brain.
56. How may it be changed?
By the process we call thinking. Thoughts produce brain cells, and these cells respond to the corresponding thought in the Universal.
57. Of what value is the power of concentration?
It is the very highest personal accomplishment which can be acquired, and the distinguishing characteristic of every successful man or woman.
58. How may it be acquired?
By faithfully practicing the exercises in this System.
59. Why is this so important?
Because it will enable us to control our thoughts, and since thoughts are causes conditions must be effects; if we can control the cause we can also control the effect.

Improve Brain Health Now: Easy Steps
We can summarize a lot of research by saying that there are
four essential pillars to maintaining a healthy brain that
functions better now and lasts longer. Those pillars are:
- 1) Physical Exercise
- 2) Mental Exercise
- 3) Good Nutrition
- 4) Stress Management
Great … now what?! How do you develop a healthy lifestyle that includes all four pillars? Let’s look at each one.
- - Start by talking to your doctor, especially if you are not currently physically active, have special health concerns, or are making significant changes to your current program.
- - Set a goal that you can achieve. Do something you enjoy for even just 15 minutes a day. You can always add more time and activities later.
- - Schedule exercise into your daily routine. It will be become a habit faster if you do.
- - If you can only do one thing, do something cardiovascular, meaning something that gets your heart beating faster. This includes walking, running, skiing, swimming, biking, hiking, tennis, basketball, playing tag, ultimate Frisbee, and other similar sports/activities.
- - Be curious! Get to know your local library and community college, look for local organizations or churches that offer classes or workshops
- - Do a variety of things, including things you aren’t good at (if you like to sing, try painting too)
- - Work puzzles like crosswords and sudoku or play games like chess and bridge
- - Try a computerized brain fitness program for a customized workout
- - If you can only do one thing, learn something new every day
- - Eat a variety of foods of different colors without a lot of added ingredients or processes
- - Plan your meals around your vegetables, and then add fruit, protein, dairy, and/or grains
- - Add some cold-water fish to your diet (tuna, salmon, mackerel, halibut, sardines, and herring) which contain omega-3 fatty acids
- - Learn what a portion-size is, so you don’t overeat
- - Try to eat more foods low on the Glycemic Index
- - If you can only do one thing, eat more vegetables, particularly leafy green ones
4. Stress Management
- - Get regular cardiovascular exercise
- - Try to get enough sleep each night
- - Keep connected with your friends and family
- - Practice meditation, yoga, or some other calming activity as way to take a relaxing time-out (maybe a bath)
- - Try training with a heart rate variability sensor, like the one in emWave (formerly known as Freeze-Framer)
- - If you can only do one thing, set aside 5–10 minutes to just breathe deeply and recharge

The Ten Habits of Highly Effective Brains
Let’s review some good lifestyle options we can follow to maintain, and improve, our vibrant brains.
- Learn what is the “It” in “Use It or Lose It”. A basic understanding will serve you well to appreciate your brain’s beauty as a living and constantly-developing dense forest with billions of neurons and synapses.
- Take care of your nutrition. Did you know that the brain only weighs 2% of body mass but consumes over 20% of the oxygen and nutrients we intake? As a general rule, you don’t need expensive ultra-sophisticated nutritional supplements, just make sure you don’t stuff yourself with the “bad stuff”.
- Remember that the brain is part of the body. Things that exercise your body can also help sharpen your brain: physical exercise enhances neurogenesis.
- Practice positive, future-oriented thoughts until they become your default mindset and you look forward to every new day in a constructive way. Stress and anxiety, no matter whether induced by external events or by your own thoughts, actually kills neurons and prevent the creation of new ones. You can think of chronic stress as the opposite of exercise: it prevents the creation of new neurons.
- Thrive on Learning and Mental Challenges. The point of having a brain is precisely to learn and to adapt to challenging new environments. Once new neurons appear in your brain, where they stay in your brain and how long they survive depends on how you use them. “Use It or Lose It” does not mean “do crossword puzzle number 1,234,567″. It means, “challenge your brain often with fundamentally new activities”.
- We are (as far as we know) the only self-directed organisms in this planet. Aim high. Once you graduate from college, keep learning. The brain keeps developing, no matter your age, and it reflects what you do with it.
- Explore, travel. Adapting to new locations forces you to pay more attention to your environment. Make new decisions, use your brain.
- Don’t Outsource Your Brain. Not to media personalities, not to politicians, not to your smart neighbour… Make your own decisions, and mistakes. And learn from them. That way, you are training your brain, not your neighbour’s.
- Develop and maintain stimulating friendships. We are “social animals”, and need social interaction. Which, by the way, is why ‘Baby Einstein’ has been shown not to be the panacea for children development.
- Laugh. Often. Especially to cognitively complex humor, full of twists and surprises. Better, try to become the next Jon Stewart
Now, remember that what counts is not
reading this article-or any other-, but practicing a bit every day
until small steps snowball into unstoppable, internalized habits…so,
pick your next battle and try to start improving at least one of
these 10 habits today. Revisit the habit above that really grabbed your attention, click on the link to learn more, and make a decision to try something different today!

Being bilingual 'boosts brain power' (BBC)
Learning a second language can boost brain power, scientists believe.
The US researchers from Northwestern University say bilingualism is a
form of brain training - a mental "work out" that fine-tunes the mind.
Speaking two languages profoundly affects the brain and changes how the nervous system responds to sound, lab tests revealed.
Experts say the work in Proceedings of the National Academy of Sciences provides "biological" evidence of this.
For the study, the team monitored the brain responses of 48
healthy student volunteers - which included 23 who were bilingual - to
different sounds.
They used scalp electrodes to trace the pattern of brainwaves.
Under quiet, laboratory conditions, both groups - the bilingual and the English-only-speaking students - responded similarly.
But against a backdrop of noisy chatter, the bilingual group were far superior at processing sounds.
They were better able to tune in to the important information
- the speaker's voice - and block out other distracting noises - the
background chatter.
'Powerful' benefits
And these differences were visible in the brain. The bilingualists' brainstem responses were heightened.
Prof Nina Kraus, who led the research, said: "The bilingual's
enhanced experience with sound results in an auditory system that is
highly efficient, flexible and focused in its automatic sound
processing, especially in challenging or novel listening conditions."
Co-author Viorica Marian said: "People do crossword puzzles
and other activities to keep their minds sharp. But the advantages we've
discovered in dual language speakers come automatically simply from
knowing and using two languages.
"It seems that the benefits of bilingualism are particularly
powerful and broad, and include attention, inhibition and encoding of
sound."
Musicians appear to gain a similar benefit when rehearsing, say the researchers.
Past research has also suggested that being bilingual might help ward off dementia.
