This filing system is ..temporal in nature, that is, it files by date. -milum
I rather question this hypothesis. From my experience, the mind constructs "search trees" by association, weighted by emotional loading. -wsieber

Dear wsieber,

Yes I fear my remarks were poorly stated. What I think is that -events in time have a commonality that the mind stores by that association, so associated thoughts can be said to be packaged in Time Units. This is one way to enhance recall.
Of course, there are many other ways as well.

Now will you please explain what you mean by "emotional loading"?
