A blind controlled experiment. You will be randomly assigned to one of 4 conditions: 474Hz, 432Hz, 528Hz, or silence. You won't know which one until the end.
Scientific Design: ✓ Blind — you don't know your frequency condition ✓ Controlled — 4 groups: 474Hz · 432Hz · 528Hz · Silence ✓ Measurable — reaction time · word latency · pattern · memory → Use headphones · Set volume comfortably · Do not change it
