Whether infants at five months of age look mostly at faces or non-social objects such as cars or mobile phones is largely determined by genes. The findings suggest that there is a biological basis for how infants create their unique visual experiences and which things they learn most about.
Oh boy, this is kind of scary. Not that we have differences. But if you for some reason are in contact with social services, I’ve seen on a TV documentary, that they use this as a significant parameter to judge whether the infant is properly cared for.
I bet practices differ, but it seemed like if the infant didn’t seek eye contact, that was something that was universally accepted as a very negative sign.
The documentary I saw, there was actually a couple that had their infant child taken away, partially based on this issue! I’m not saying they made a mistake, but there definitely is a potential for it.
