Really neat article. I'd probably change the title to "How Kids Scan..." I was expecting something more about the inner model folks build for what makes up the world.

It would be interesting to me if this was somehow a physical characteristic of the eye. I'd also be interested to know if there are somehow more "optimal" methods of scanning than others.

Tangentially, I do worry about the emphasis on eye contact in children. It is almost like we punish kids for not wanting to look at us. It certainly seems to help know they are listening, but it is worrying to have tension just because someone doesn't want to make eye contact.

Just give your child a mobile device. You won't have to worry about making eye contact again, until you take it away :^) Really, not worrying whether your kids learn to pay attention to eyes and faces to understand other people around them, is about like not worrying whether they learn to speak or read. These things might just happen, but if they don't you will both be really miserable by the time they are 10.

Cool study, but it is my understanding that twin studies have a tendency to erroneously assume genetic causation since they fail to control for conditions the twins share in prenatal environments, which can (and do) affect behavior.

In this particular study, identical twins are compared against fraternal twins, which do share the prenatal environment.

They controlled for that by having about as many fraternal twins in this study, though.

It's particularly surprising to me that they got very similar results with regards to discrepancy between fraternal and identical twins when testing again at a later age.

High School teacher here. I generally try not to take offense when I am talking to a student and they don't make much eye contact. Some of my coworkers take great offense when students don't make eye contact but I think it's just something that teenagers don't do (with adults/uthoroty figures). Also, some of my students are giving you the most attention when they are NOT looking at you.

Doesn't help that student desks are too damn short so talking to a sitting student forces you to loom over them like some cartoonesque evil authority figure. No one likes making eye contact in that kind of situation.

It's not clear from the summary or a very quick glance at the articles whether the researchers controlled for sex differences or impact on parent attitudes towards fraternal twins. It is sensible to assume that one sex will imitate dad while the other will imitate mom, or that one toddler receives more attention than another from either parent. Might anyone familiar with the topic have some insights on this?
