How many times can you use the walk-through-your-house technique without reducing the strength of the associations ? I can see how useful it would be to use it once - milk on your front doorstep, steaks attacking you in the foyer, it makes sense, but what about the next time you want to remember something? Perhaps, the next time I want to remember a sequence of numbers starting with zero and I will have Ozzy Ozborne on my front door step. After that maybe I want to remember something else and I might have something random on my front doorstep like a mental image of Jack Bauer with a gun .. After a few goes at doing this how will I remember what is supposed to go on my front doorstep at all ?? Does anyone have experience of this ?
