I never knew there would be a good use for raisins, I mean this is a fruit which disguises itself as a chocolate chip so that people will actually eat a raisin cookie. Don't tell me you haven't accidentally picked up a raisin cookie when you wanted chocolate chip. It's one of the most disappointing food surprises out there. Anyway, researchers in child intelligence testing have found a way to have raisins predict how well a toddler will do in school. I know. This is crazy talk.
Researchers tested hundreds of 20-month-old children by placing a raisin under a cup and telling them to wait until they were told to eat the raisin. The Telegraph reports the test seems simple enough but can be "excruciating" for a young child and many will fail. In the end, researchers found that toddlers who successfully waited to eat the raisin had an IQ seven points higher when they were 8.
This test assesses inhibitory control in young children and later attention span issues.
Frankly, if I were given this test, I'd sit there forever before someone made me eat that raisin. But if parents want to try this on their own young pre-schoolers, they could probably get away with using a fruit kids actually like.
