What this video covers
Think-aloud is a usability-testing method where participants speak their thoughts as they complete a task - what they’re looking for, expecting, or uncertain about. It turns silent actions into spoken commentary, revealing not just where someone struggles but why, exposing hesitation and flawed mental models that a screen recording alone can’t capture.
Watch in silence and you see a cursor wander and a wrong click - but not why. Switch the narration on and suddenly there's a reason: "I'm looking for a basket icon… is that it? No…" The hesitation, the wrong assumption, the moment it clicked - all of it spoken aloud. That "why" is the difference between knowing something went wrong and knowing how to fix it.
