60秒科学:老者吐真言Elderly with Cognitive Decline Off

Elderly people with loss of executive function--lessening of inhibitions--are more likely to offer useful, but tactless, advice. Christopher Intagliata reports

上了年纪的人失去了决策的作用后——自身抑制力的减弱——更有可能提出有用的但不那么老练的建议。——Christopher Intagliata 报道

You know how grandma's always criticizing your new haircut or choice of clothing? Well, it might not hurt to listen. Because old folks who can't hold their tongues may give the best advice. That’s according to a study in the Journal of Experimental Social Psychology¹.

Researchers recruited 19 undergrads and 32 adults in their 60s and 70s. They split the older adults into two groups, based on the adults' abilities to control their behaviors and impulses—called executive function, which naturally declines with age. Then the researchers showed all three groups a photo of a visibly obese² teen, along with a list of her complaints, like trouble sleeping and lack of energy—symptoms associated with childhood obesity³.

What advice could they offer this girl? Well, only half of the higher functioning adults and a third of the college kids brought up the girl's weight as the possible source for her problems. But 80 percent of the adults with cognitive⁴ declines mentioned weight. They also gave twice as many helpful tips, like more exercise, a better diet, and delivered them with more empathy. So next time you need advice, try grandma or grandpa. But be prepared for brutal honesty
