Why Bilinguals are Smarter

CCK Note: That is why it is important to teach young children multiple languages, the earlier the better. Language researches also found that children unlike adults can handle multiple languages without problem - they are highly adaptable!


Mar 19, 2012, New York TImes

Speaking two languages rather than only one has obvious practical benefits in an increasingly globalised world. But in recent years, scientists have begun to show that the advantages of bilingualism are even more fundamental than being able to converse with a wider range of people.

Being bilingual, it turns out, makes you smarter. It can have a profound effect on your brain, improving cognitive skills not related to language and even shielding against dementia in old age.

This view of bilingualism is remarkably different from the understanding of bilingualism through much of the 20th century. Researchers, educators and policymakers long considered a second language to be an interference, cognitively speaking, that hindered a child's academic and intellectual development.

They were not wrong about the interference: There is ample evidence that in a bilingual's brain, both language systems are active even when he is using only one language, thus creating situations in which one system obstructs the other.

But this interference, researchers are finding out, isn't so much a handicap as a blessing in disguise. It forces the brain to resolve internal conflict, giving the mind a workout that strengthens its cognitive muscles.


HONING OUR FOCUS

Bilinguals, for instance, seem to be more adept than monolinguals at solving certain kinds of mental puzzles.

In a 2004 study by psychologists Ellen Bialystok and Michelle Martin-Rhee, bilingual and monolingual preschoolers were asked to sort blue circles and red squares presented on a computer screen into two digital bins - one marked with a blue square and the other marked with a red circle.

In the first task, the children had to sort the shapes by colour, placing blue circles in the bin marked with the blue square and red squares in the bin marked with the red circle. Both groups did this with comparable ease.

Next, the children were asked to sort by shape, which was more challenging because it required placing the images in a bin marked with a conflicting colour. The bilinguals were faster at performing this task.

The collective evidence from a number of such studies suggests that the bilingual experience improves the brain's so-called executive function - a command system that directs the attention processes that we use for planning, solving problems and performing various other mentally-demanding tasks.

These processes include ignoring distractions to stay focused, switching attention wilfully from one thing to another and holding information in mind - like remembering a sequence of directions while driving.


ABILITY TO KEEP TRACK

Why does the tussle between two simultaneously-active language systems improve these aspects of cognition?

Until recently, researchers thought the bilingual advantage stemmed primarily from an ability for inhibition that was honed by the exercise of suppressing one language system: This suppression, it was thought, would help train the bilingual mind to ignore distractions in other contexts.

But that explanation increasingly appears to be inadequate, since studies have shown that bilinguals perform better than monolinguals even at tasks that do not require inhibition, like threading a line through an ascending series of numbers scattered randomly on a page.

The key difference between bilinguals and monolinguals may be more basic: A heightened ability to monitor the environment.

"Bilinguals have to switch languages quite often - you may talk to your father in one language and to your mother in another language," says Mr Albert Costa, a researcher at the University of Pompea Fabra in Spain. "It requires keeping track of changes around you in the same way that we monitor our surroundings when driving."

In a study comparing German-Italian bilinguals with Italian monolinguals on monitoring tasks, Mr Costa and his colleagues found that the bilingual subjects not only performed better, but they also did so with less activity in parts of the brain involved in monitoring, indicating that they were more efficient at it.


FROM BABES TO OLD FOLK

The bilingual experience appears to influence the brain from infancy to old age (and there is reason to believe that it may also apply to those who learn a second language later in life).

In a 2009 study led by Ms Agnes Kovacs of the International School for Advanced Studies in Trieste, Italy, seven-month-old babies exposed to two languages from birth were compared with peers raised with one language.

In an initial set of trials, the infants were presented with an audio cue and then shown a puppet on one side of a screen.

Both infant groups learned to look at that side of the screen in anticipation of the puppet.

But in a later set of trials, when the puppet began appearing on the opposite side of the screen, the babies exposed to a bilingual environment quickly learned to switch their anticipatory gaze in the new direction, while the other babies did not.

Bilingualism's effects also extend into the twilight years.

In a recent study of 44 elderly Spanish-English bilinguals, scientists led by neuropsychologist Tamar Gollan of the University of California, San Diego, found that individuals with a higher degree of bilingualism - measured through a comparative evaluation of proficiency in each language - were more resistant than others to the onset of dementia and other symptoms of Alzheimer's disease: The higher the degree of bilingualism, the later the age of onset.

Nobody ever doubted the power of language. But who would have imagined that the words we hear and the sentences we speak might be leaving such a deep imprint?

Great Recession of 2008 (draft)

WHERE
This crisis started in the US and spread to Europe. The whole world were affected but less so than those 2 regions.

WHY
Monetary expansion (by way of increase of credit or debt esp. in US and Europe) in early/mid 2000s caused bubbles to develop in various markets (like stock, housing, commodities) all over the world.

As prices of everything rose, more and more people used borrowed money to invest and profit from rising prices.

By 2007, shares in US and Europe for example were trading at PE of 20. Average US house prices ($230K) were more than 4 times median household income ($50K).

The US and European countries had huge amounts of private and public sector debts that were more than 200% of their countries' GDP. The UK is the worst with total debt of more than 500% GDP (85% government but 800% banks and private sector)!

Those governments used private consumption financed by debts as a way to keep their economies 'growing' but those growth were not from production.

Note: Since the start of 'modern' fractional banking system about 100 years ago, debt can be created almost unlimitedly. That is why there were so many crises in the past 100 years (one every 10 years or so).

WHAT HAPPENED

World Wide
From 1990s onwards, outsourcing and shifting of factories to lower cost countries (like China which was just admitted into WTO) reduced the number of jobs available in the US and Europe.

In addition, global economy slowed/shrank as a result of the bursting of the Internet Bubble in 2001-02. To re-inflate their economies, those governments increased public spending financed by government borrowings and lowered the cost of money to encourage their people and businesses to borrow money to spend and invest.

But because most of their productive industries had already moved out or had been decimated over the decades before that, there were fewer real investment options in the western countries. As a result, the increasing borrowings were directed into their housing and financial markets which went up in value and created the illusion of wealth.

In reality, they created ponzi-like bubbles that later burst. People who borrowed early on in the cycle made a lot of money but those that joined in late suffered huge losses.

Government debt growth were also aided by global banking 'regulations' (developed by the same governments) that encouraged banks to make loans to governments. Basel II regulations, for example, did not require banks to reserve capital for holdings of OECD government bonds because of the assumption they were 'risk-free'!


US
From 2002 onwards, their Federal Reserve lent money out at very low rates and as a result there were more money available than real business to invest them in.

(Note: the terrible state of their economy may be a reason behind 'Sept 11' where the World Trade Center buildings that house a lot of bank offices were 'attacked' and a 3rd building (Building 7) that housed many government offices from CIA, DOD to SEC were 'taken down'. Documents of those bodies including thousands of SEC cases were destroyed in Building 7. Their subsequent attack of Afghanistan and Iraq were to re-stimulate the economy - by increasing spending and employment in defense sector - and to control world oil)

Some people said the other reason for so much money floating around was because foreign governments with trade surplus were 'lending' them back to the US government (by buying US treasuries). But foreign countries had so much USD because the US were printing them to buy things from foreigners in the first place. Foreigners' fault were to stupidly accept them thinking that those USD will 'keep its value'.

Banks looking for borrowers then gave easy loans to people to buy houses. The government aided by passing new laws to promote house ownership with the idea that with people rushing to buy houses, rising prices will increase consumer 'wealth' and people will spend more thus supporting the economy. That started a bubble where rising house prices enticed more and more people (including those that cannot afford it known as 'sub-prime borrowers') to jump into the housing market in the hope of making easy money. It worked till 2006 when house prices peaked.

In 2007 the housing bubble burst & house prices fell causing US banks to start collapsing in 2008 because house owners stopped servicing and repaying their loans (many loan terms allowed people to get out by just returning the house keys without further penalty). The US government stepped in to arrange for other 'more healthier' banks to buy up the small ones like Countrywide, WaMu, Bear Stearns etc. and to help mortgage holders 'restructure' their loans to try and stop people from defaulting and abandoning their houses/loans (and thus making the problem worse).

Initially, they tried to say that it was just a 'sub-prime crisis' i.e. only people who had never been able to afford the loans that were defaulting.

But the problem worsened and the US government had to bail out the bigger 'too big to fail' banks like Citibank, BOA, etc too firstly by buying the mortgage backed securities (MBS, backed by those bad housing loans) from those banks and then outright cash injection in return for share (e.g. Citibank).

In October 2008, the Fed refused to bail out Lehman Brothers and the bankruptcy of that bank triggered a huge liquidity problem in the banking system where huge amounts were withdrawn from banks (bank run) and banks refused to lend to each other for fear of being caught by another bankrupting bank.

The 'sub-prime crisis' had morphed to 'housing loan crisis' and then 'bank solvency crisis' and after that 'liquidity crisis'. Basically, all hell broke loose!

The housing bubble and banking collapse brought on a collapse of wealth and consumption thus affecting the whole economy and businesses started retrenching people to cut costs etc. Unemployment rate jumped to 10-20% depending on which measure/source is used.

Companies like GE, GM etc were also given government bailout money. Some critics called it 'iron rice bowl for the capitalists'.

To promote consumption to re-inflate the economy the government even subsidised car purchases ('Cash for Clunkers' programme). In Q4 2011, car purchases jumped 50% because of easy loans. The country just moved from easy loans to buy houses to easy loans to buy cars (car sales is 20% of total US retail sales). 45% of borrowers were 'sub-prime' (again)!

With shrinking tax from abandoned houses (housing tax is quite high in US), high unemployment and collapsing economy, municipal, state and central government revenues collapsed resulting in their inability to service their already high public debts. Again, their Fed stepped in to 'bail out'.

They were bailing out everyone but in doing that the government had effectively transferred all the bad debts previously held by banks and companies into the 'country's books' meaning the whole country (instead of bank and company shareholders) ended up having to pay for those bad debts.

All those crises above had morphed into 'sovereign debt crisis'.

The bailing out of mortgage holders, banks, companies and state/municpal/central governments by the Federal Reserve caused the US central government debt level and the country's money base (and balance sheet) to soar. The already high US federal debt increased by $4-5T (from $9T to $14.5T) and money base grew from 800B in 2008 to 2.4T in 2012.

In addition, most of the adjustable rate or ARM housing loans (esp. those by subprime borrowers) which were issued during the boom with 'teaser rates' were due for interest rate resets starting around 2010 through 2012. To pre-empt further collapse of the housing market and banks' loan books the US government actively suppressed interest rates to lighten loan servicing costs, and the Fed even announced they will keep rates low till 2014! Banks were allowed to do away with marking-to-market their bad MBS holdings to hide their loses.

To deflect world attention from the US 'refinancing problem', their media tried to focus on talks of a 'double dip' and debt problems in EU countries (like the PIIGS) as a way to spook people to stay away from stock markets and keep their money in cash and 'safe haven bonds' (meaning US bonds) which in effect reduces their borrowing cost. As result, in 2009 and 2010 I heard many people talking/advising others to 'keep cash'.

The bail out money and low interest rates in effect is 'money printing' and caused holders of US bonds like China to express concerns about the US Dollar's value, and Brazil to raise concerns of 'currency wars' (where governments compete to devalue their currencies to gain competitive advantage).

2009: US Fed started paying interest on 'excess reserves' banks put with US Fed. This allows US banks to earn interests from banks' excess cash. Bank excess cash comes from:
 - 'loan loss reserves' (for bad loans)
 - cash they cannot lend out due to lack of demand by people deleveraging
 - cash from selling sub-prime assets to US Fed
2010 Q2-Q3: reports of US banks increasing substantially their interest rate swap (IRS) books to support low US bond interest rates and illusion of demand for US bonds and 'flight to US safety'.

2011 Q2: reports of US Fed selling put options on US bonds to support price of those bonds and keep interest rates low.


Rest of the World

In Europe and elsewhere in the world, similar housing bubbles appeared about the same time as the US housing bubble because other governments also expanded credit and money supply to 'match' the US as part of keeping their currencies from appreciating too much against USD.

In addition, the introduction of Euro in 2001 lowered cost of debt for less competitive European countries (like Portugal, Italy, Ireland, Greece and Spain) which encouraged them to borrow more.

So when the US housing bubble collapsed, the same thing happened elsewhere to varying degrees. The government responses were also very similar all round the world - bank bail outs, reduction in interest rates, subsidies to promote consumption etc.

Europe's public debts were like the US. In addition, their banks were holding a lot of the US mortgage backed securities (MBS) 'backed' by US housing loans! (a sort of double whammy). Some of those MBS were also sold to other parts of the world.

Others in the world bought those US MBS because they were rated 'AAA' by rating agencies paid to do the rating by US banks that packaged them! In addition, all the 3 top rating agencies (S&P, Fitch, Moody's) were American! See how stupid the world is?

The first country to 'fall' was Iceland. Next was Ireland and then Greece. The top topic of the 'next one to go' was the weak PIIGS countries using the Euro: Portugal, Ireland, Italy, Creece and Spain.

See separate writeup on 'Eurozone Crisis' - Europe has similar problem of over indebtedness by government and private sector as US and UK but are undertaking slightly different solutions due to their 'lack of fiscal union' and refusal to solve problem by 'money printing'.

4. Scan Titles for Big Picture: Scan titles of news or articles for new or interesting topics. Read the interesting ones. There are too many articles to read all everyday. Look out for 'Macro Economic Linkages' (how one event is related to other events elsewhere)  http://cckplanetblog.blogspot.com/2012/02/macro-economic-linkages.html

5. Know More Details (KEY MARKET INDICATORS, COUNTRY specific news): Once a while, take a look at some key economic and market indicators (for big picture view) or go to country specific sections when you need more details from/about that country.

6. Company Details: Last section provide links to sites where you can get information about individual companies around the world like share price history, company financials, etc.


Caution:
1. Remember 'Elephant and Blindmen' - never believe what is said in any one article or source from a country, always check other sources from other parts of the world and think!

2. History is the key. News reports are just snapshots of what happened yesterday. Just like a 1 second snippet from a 2 hour movie, one cannot tell the true story by just looking at the snippet. 'Daily news' are of little value for people without 'big picture' and knowledge of history.

Notes:
1. Key Economic Indicators of US listed above are just indicators on state of US economy and is not applicable to the whole world! They are watched because the US is (was) the world largest consumer and buy things from all round the world. When their economy is not doing well, others who sell to them MAY suffer along. But that will not be the case in future when the US becomes less relevant to the world.

2. Each news source is like a different window to the world, each allows you to look at the outside at a different angle. It is your responsibility to put those different perspectives together to form the best picture.

3. Powerful people use the press to manipulate public opinions to their favour. That is why all governments want to control the newspapers in their countries by either directly owning them or issuing printing licenses to people who support them.

Quotes:
Those who don't read newspapers are under-informed, those who do are mis-informed - Mark Twain
Freedom of the press is limited to those who own one - AJ Liebling
Men who do not know history will forever be boys - Tacitus (Roman Historian)
