Do children see darkness as “blacker” than adults?
Plinth: Thanks, both for explaining why the noise occurs, and providing what, I think, might explain my situation, which is that most of the absolute dark conditions I am in now are self-imposed and very brief (turning off all the lights for a second to see just how dark the room is with the new thick curtains, etc), while when I was a kid, they were probably longer (playing in the dark), which means that perhaps the rhodopsin response slowness results in more noise during my brief testing than during my more extended darkness testing as a kid.
