Video narration
Why can an instruction for a new app vanish seconds after you hear it? Sights and sounds briefly enter sensory memory: a fleeting trace of incoming information. Attention selects what continues; some is held briefly in short-term memory. Working memory overlaps with it: it's the active workspace where you hold and use an instruction, like finding a menu. These aren't four rigid boxes; they describe information being noticed, held, used, and stored. The turn: attention and active use matter-not information passing through a pipeline. Connect the menu to something familiar, use it, and retrieve the steps instead of rereading. That supports long-term memory: knowledge and skills available later. Forgetting is not proof you're bad at learning; information can be lost when attention drops. So, why did it vanish? When attention and active use drop. It sticks when you connect it, use it, and retrieve it again.
