Very fair point, thank you! I'm not sure I entirely agree with everything, but I was definitely missing the change in the accessibility of the disruptions. You're probably right that the more immediate the notification is, the higher are the chances that it'll interfere with our attention in a way that's could introduce some undesirable effects. Definitely there's a difference between a mail arriving, phone or watch buzzing, and something instantly appearing in the visual field.

Thanks for the response, and I apologize if I came off too sharply!
