This　study　aims　to　analyze　the　effects　of　subliminal　stimulus　messages　delivered　by　humans　unconsciously　after　certain　sound　or　image　clips　are　played　simultaneously　at　every　25　frames　or　50　frames　or　alternatively　at　certain　intervals　in　application　of　the　Mask　Effect　Mixing　method.　As　a　result,　the　frame　rates　of　images　decreased　from　1/50　to　1/25,　and　as　the　play　of　images　and　sounds　turns　from　asynchronism　to　synchronism,　the　rate　of　human　memory　enhanced.　As　time　passed,　the　rate　of　memory　gradually　decreased.　In　the　future,　it　is　thought　that　the　findings　of　this　study　will　contribute　to　sales,　behaviors,　and　communication　effects　as　well　as　learning　efficiency　when　applied　to　advertisement　or　learning.　©　2015　Taylor　&　Francis　Group,　London.
