I haven’t read the paper. But if the researchers were bringing in children regularly for testing involving eye tracking equipment, why not also test their ability to manipulate physical objects, recognize faces, and track faces? That all seems like low hanging fruit.

I often have this thought about research and usually assume that the answer is cost/resources.

Research seems poorly directed, like lots of ad hoc studies without cooperation and planning for how it will be used for the sector overall.

Not a research scientist; probably a very naive view. Maybe there's more higher level cooperation/symbiosis/planning/whatever than I perceive?
