Menschen blinzeln weniger, wenn sie in lauten Umgebungen intensiver daran arbeiten, Sprache zu verstehen. Dies legt nahe, dass das Blinzeln die mentale Anstrengung widerspiegelt, die hinter dem Zuhören steckt, während die Blinzelmuster bei unterschiedlichen Lichtverhältnissen stabil bleiben

Consistency across lighting environments makes sense due to pupil dilation. So that’s no surprise.
The relationship to mental concentration is more interesting but also seems fairly intuitive? If you think of concentration as a survival mechanism, like an extension of fight or flight, perhaps, it makes sense that a momentary blink could result in a critical failure to react to a momentary change in stimuli. Same reasoning could explain why you might find yourself holding your breath when you’re on the very cusp of completing a complex task, like the last multiple choice question of an exam, or why you might let out a sigh when you resign for a moment after determining that you don’t know the solution and need to change strategies. It could also be a manifestation of an adapted FoF stress response. Don’t move. Don’t blink. Don’t breathe. Just focus.
I think we blink less because in noisy environments we use visual aids to understand speech better, such as facial expressions and mouth movement. The more the voice is lost in noise, the more we rely on help from other cues.
Hold on, I can’t read this. Let me turn down my music first.
people blink less when they are concentrating. nothing new here.
