Why Bilinguals Are Smarter

SPEAKING two languages rather than just one has obvious practical benefits in an increasingly globalized 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 policy makers 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.

Bilinguals, for instance, seem to be more adept than monolinguals at solving certain kinds of mental puzzles. In a 2004 study by the 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 color, 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 color. The bilinguals were quicker at performing this task.

Upper class people more likely to cheat: study

In two field studies on driving behavior, upper-class motorists were found to be four times more likely than the other drivers to cut off other vehicles at a busy four-way intersection and three times more likely to cut off a pedestrian waiting to enter a crosswalk. Another study found that upper-class participants presented with scenarios of unscrupulous behavior were more likely than the individuals in the other socio-economic classes to report replicating this type of behavior themselves.

Participants in the fourth study were assigned tasks in a laboratory where a jar of candy, reserved for visiting children, was on hand, and were invited to take a candy or two. Upper-class participants helped themselves to twice as much candy as did their counterparts in other classes.

In the fifth study, participants each were assigned the role of an employer negotiating a salary with a job candidate seeking long-term employment. Among other things, they were told that the job would soon be eliminated, and that they were free to convey that information to the candidate. Upper-class participants were more likely to deceive job candidates by withholding this information, the study found.

In the sixth study, participants played a computerized dice game, with each player getting five rolls of the dice and then reporting his or her scores. The player with the highest score would receive a cash prize. The players did not know that the game was rigged so that each player would receive no more than 12 points for the five rolls. Upper-class participants were more likely to report higher scores than would be possible, indicating a higher rate of cheating, according to the study.
