Thinking You’re Too Old to Learn a New Language? Think Again

I’m not sure what the sample size is, or how old the adults in the study are, but:

Ferman and Avi Karni from the University of Haifa, Israel, devised an experiment in which 8-year-olds, 12-year-olds and adults were given the chance to learn a new language rule. In the made-up rule, verbs were spelled and pronounced differently depending on whether they referred to an animate or inanimate object.

Participants were not told this, but were asked to listen to a list of correct noun-verb pairs, and then voice the correct verb given further nouns. The researchers had already established that 5-year-olds performed poorly at the task, and so did not include them in the study. All participants were tested again two months later to see what they remembered.

“The adults were consistently better in everything we measured,” says Ferman. When asked to apply the rule to new words, the 8-year-olds performed no better than chance, while most 12-year-olds and adults scored over 90 per cent. Adults fared best, and have great potential for learning new languages implicitly, says Ferman. Unlike the younger children, most adults and 12-year-olds worked out the way the rule worked – and once they did, their scores soared. This shows that explicit learning is also crucial, says Ferman, who presented the results at the International Congress for the Study of Child Language in Montreal, Canada, this week.

After Middle Age, People Get Happier As They Get Older

U-Curve

Via the MetaFilter discussion on the happiest man in America:

Ask a bunch of 30-year-olds and another of 70-year-olds as Peter Ubel, of the Sanford School of Public Policy at Duke University, did with two colleagues, Heather Lacey and Dylan Smith, in 2006 which group they think is likely to be happier, and both lots point to the 30-year-olds. Ask them to rate their own well-being, and the 70-year-olds are the happier bunch. The academics quoted lyrics written by Pete Townshend of The Who when he was 20: “Things they do look awful cold / Hope I die before I get old”. They pointed out that Mr Townshend, having passed his 60th birthday, was writing a blog that glowed with good humour.

Mr Townshend may have thought of himself as a youthful radical, but this view is ancient and conventional. The “seven ages of man”—the dominant image of the life-course in the 16th and 17th centuries—was almost invariably conceived as a rise in stature and contentedness to middle age, followed by a sharp decline towards the grave. Inverting the rise and fall is a recent idea. “A few of us noticed the U-bend in the early 1990s,” says Andrew Oswald, professor of economics at Warwick Business School. “We ran a conference about it, but nobody came.”

Since then, interest in the U-bend has been growing. Its effect on happiness is significant—about half as much, from the nadir of middle age to the elderly peak, as that of unemployment. It appears all over the world. David Blanchflower, professor of economics at Dartmouth College, and Mr Oswald looked at the figures for 72 countries. The nadir varies among countries—Ukrainians, at the top of the range, are at their most miserable at 62, and Swiss, at the bottom, at 35—but in the great majority of countries people are at their unhappiest in their 40s and early 50s. The global average is 46.

A Healthy Lifestyle May Not Affect Your Longevity

Centenarians

SCIENTISTS have discovered the “Methuselah” genes whose lucky carriers have a much improved chance of living to 100 even if they indulge in an unhealthy lifestyle.

The genes appear to protect people against the effects of smoking and bad diet and can also delay the onset of age-related illnesses such as cancer and heart disease by up to three decades.

No single gene is a guaranteed fountain of youth. Instead, the secret of longevity probably lies in having the right “suite” of genes, according to new studies of centenarians and their families. Such combinations are extremely rare — only one person in 10,000 reaches the age of 100.

Also, an active social life beyond one’s own family contributes to one’s longevity, happiness, and intelligence in later life.
