I grew up with unlimited screen time starting at age 2 and used the majority of it to play 3d video games. I score very high on the VVIQ.

My story is antidotal, but your hypothesis is also not backed by data. I'd like to purpose a counter hypothesis: spending time in interactive 3d worlds requires building internal maps of the environment. Exercising these portions of the brain improves Visual Imagery Vividness.

There are lots of unforeseen consequences of screen time. I suspect this isn't one of them.

I'll second this hypothesis. Also unlimited 3d world time: I have _vivid_ recollections of very large maps, spaces, etc.

I can remember every WoW raid environment, every detail of every CS map I played, etc.
