OLYMPUS DIGITAL CAMERAYou never know what you’ll find at Andrew Sullivan’s blog.

Today he notes research on the memory of toddlers. A new study has demonstrated that three-year-olds have memories of  seeing someone once, back when they were one.

Danish researcher Osman “Kingo and his team first renewed contact with parents and their children who’d taken part in an earlier study when the children were age one. That earlier research involved the infant children interacting with one of two researchers for 45 minutes – either a Scandinavian-Caucasian man or a Scandinavian-African man.

“Now two years on, 50 of these parents and children – the latter now aged three – were invited back to the exact same lab (hopefully cueing their earlier memories). Here the children were shown two simultaneous 45-second videos side by side. One video was a recording of the researcher – either the Scandinavian-Caucasian or Scandinavian-African man – interacting with them two years earlier; the other video showed the other researcher (the one they hadn’t met) interacting with a different child in the exact same way. …

“The children spent significantly more time looking at the video that featured the researcher they’d never met. … This result provides strong evidence that the children had some recognition of the researcher they’d met, and were drawn more strongly to look at the unfamiliar researcher.”

I am especially delighted that there’s a bit of proof for what I have long insisted was true. (No one ever believes that I remember taking my first steps.)

“Elizabeth S. Spelke,” writes Natalie Angier in today’s NY Times, is a “professor of psychology and a pre-eminent researcher of the basic ingredient list from which all human knowledge is constructed.” She studies babies  to learn how much knowledge humans start out with. And perhaps not surprising, she finds that babies are intensely focused on … other people.

“Dr. Spelke studies babies not because they’re cute but because they’re root. ‘I’ve always been fascinated by questions about human cognition and the organization of the human mind,’ she said, ‘and why we’re good at some tasks and bad at others.’

“But the adult mind is far too complicated … ‘too stuffed full of facts’ to make sense of it. In her view, the best way to determine what, if anything, humans are born knowing, is to go straight to the source, and consult the recently born. …

“Dr. Spelke is a pioneer in the use of the infant gaze as a key to the infant mind — that is, identifying the inherent expectations of babies as young as a week or two by measuring how long they stare at a scene in which those presumptions are upended or unmet. …

” ‘Why did it take me 30 years to start studying this? … All this time I’ve been giving infants objects to hold, or spinning them around in a room to see how they navigate, when what they really wanted to do was engage with other people!’ ”

John sent me this heavenly video from a Public Broadcasting show called “The Human Spark.” Do watch it. It isn’t long.

It highlights research with both chimps and toddlers, showing what is apparently an innate impulse to help others. Interestingly, whereas the chimp will pass you something you are reaching for and stop at that, a toddler will go above and beyond — and seem to enjoy it.

All of which suggests to me that if you want to be around people who are truly human, hang out with the ones who like to help others.

In a recent study of professions that involve intensive memorization, London cab drivers were found to have brains with swollen hippocampi. Not even doctors or so-called memory champions show that effect. Andrews Sullivan has the story.

Says researcher Eleanor Maguire, “We’re in a situation where people are living longer and often have to retrain or re-educate themselves at various phases in their lives. It’s important for people to know that their brains can support that. It’s not the case that your brain structure is fixed.”

A cabbie competes against a satellite system in a really cool video.
