In experiments, a newborn of a few hours will reflexively dodge/cower from a quickly growing shape circle on a screen (something is approaching and about to collide!). It has no experience at that point of being struck by any moving object or anything like that.

New borns can barely hold their heads up.

Shine a light in their eyes, and yes they react. As does everything else with eyes.

Some animals (and people) with eyes are blind and so probably don't react when you shine a light at them.

Couldn't you control for that by showing a shrinking circle on a screen? I'd be amazed if the experiment didn't do something like that.

Or the experimenter interprets any reflex according to his theory.
