Problem
A dense slide remains unchanged while the narration adds new details, causing viewers to miss later points because they are still reading earlier ones.
Solution
Root Cause / Diagnostic:
Static presentation slides loaded with dense text trigger visual-auditory competition known as the redundancy effect. When viewers attempt to read ahead through static bullet points, their phonological loop becomes saturated, causing them to completely tune out subsequent spoken analysis.
Actionable Fix:
1. Progressive Text Unmasking: Configure slide animations to reveal only one conceptual bullet point at a time using a 250ms ease-in opacity fade.
2. Word-Count Constraint: Restrict on-screen slide text to a maximum of six words per bullet point and no more than four bullets per slide layout.
3. Audio-Visual Synchronization Review: Play back the timeline to confirm each visual line unmasks within 100ms of the corresponding vocal prompt.
Pro Tip:
Treat on-screen text as a mental chapter heading rather than a script; let the slide provide the memory anchor while the voiceover delivers the analytical payload.
