Researchers indicated parents who want to test the future intelligence of the toddlers they’re raisin’ might just need a dried grape and cup.
Michael Harthorne wrote for Newser the researchers claim they can predict an 8-year-old’s academic success when the child is a toddler by putting a raisin under a cup and telling the child not to eat it until told.
The test sounds easy, Sarah Knapton wrote for The Telegraph.
But it’s “excruciating” for youngsters — most failing.
“However, those who show enough self-discipline to wait for a whole minute are destined for greatness, according to academics,” The Telegraph’s report read. “By the age of 8, the youngsters who resist temptation will have an IQ of seven points higher than those who ate the fruit early.”
The game tests attention span and capacity to learn, Tammy Hughes wrote for the Daily Mail. Study author Dieter Wolke said it’s an “easy and effective” tool in assessing control in young children.
Researchers tested 558 children at 20 months for the study, according to the Daily Mail. Results indicated the subjects born prematurely at 25 to 38 weeks were likelier to take the raisin early than those born at 39 to 41 weeks.
