This is something I noticed with our toddlers. If they are watching something on mom's phone they will stay engrossed basically as long as we let them, regardless of who or what is around them. But if we put the same exact thing on a big TV and make them sit 3-4 meters away from it, often their attention will (eventually) wander away and they'll start playing on the various toys in the room.

My theory was that the phone/tablet device is so close it occupies all of our vision. Plus our eyes are focused on something close to us, so looking at something else requires that momentary refocusing of our lenses. We basically have tunnel vision on the device. But, assuming we're sitting at a normal distance from the TV, there's just a lot more stuff in our peripheral vision and we're not in quite the same zombie-watching state.

This is fascinating. I will have to read through some of these articles - I'm a teacher (1st and 2nd grade) and after we went 1-to-1 devices last year I noticed kids were getting to afternoon and were just fried. Unable to concentrate, whiny, not retaining anything. They acted like I feel when I've had too much phone time - so I tried reducing their interactive tech time to a maximum of 30 minutes a day (still not ideal, I know, but it was something). WOW what a difference! They were way more engaged, complained less, and were able to work through lessons with me again. Too bad I finished my Master's or it would have made a fascinating research project!
