Clinician observations show that neurotypical scrolling favors consistent ramps: an initiation burst, a smooth glide, and a concise braking phase. ADHD users overshoot target anchors 2.3× more often, while ASD profiles prefer a rhythm of short micro-pauses before committing to deeper scroll depth.

Flag how the subject transitions between these phases—overshoots suggest impulsive motor initiation, while excessive micro-pauses point toward executive planning delays. Look for whether the cursor settles before the headline is centered, or if it continually oscillates around the anchor.

Record any adaptive techniques used (keyboard paging, search shortcuts, trackpad gestures). These behaviors feed into our classification engine to differentiate between excessive scanning, systematic control, and deliberate anchored navigation.
