Cognitive Benefits of Bilingualism

In stark contrast to early suspicions that bilingual children were at risk of retardation or at best, “mentally confused” (Bialystok, 2005), recent research links bilingualism to cognitive reserve and suggests it may offer protection against dementia in old age. Cognitive reserve describes a kind of resilience which appears to mediate the relationship between brain pathology and the clinical expression of that pathology; it is thought that this resilience derives from more efficient use o...

 Bilinguals Perform Better at Non-Verbal Tests

When communicating, bilinguals must successfully manage two conflicting languages; one must be accessed whilst the other is suppressed, in order to avoid involuntary language switching. The cognitive demands of this task are thought to be the origin of the bilingual advantage in executive control. A series of studies have demonstrated that bilinguals outperform their peers on tests of non-linguistic interference. Bilingual children, middle aged adults and older adults consistently record fa...

 Studies Showing the Benefits of Exercise

Scientists are also encouraged by studies on mice with a certain genetic mutation that makes them age prematurely — complete with graying and thinning fur, cataracts, hearing loss, smaller brains, enlarged hearts, anemia and thin and weak muscles — hallmark symptoms of growing older. To test whether it was possible to slow or reverse the process in these mice, a team led by Dr. Mark Tarnopolsky, a professor of pediatrics and medicine at McMaster University in Ontario, Canada, had the ro...
