General Notes:

The distinction between high and low-level identification (or identification and association) is by no means concrete (or even agreed upon, (even the existence of such a distinction isn't particularly sure)). For our purposes, the distinction we draw is that identification is the association of an "object" (or the collection of impulses which lay-people (such as us) call an object) with the pattern which represents it, while association generally relates multiple "objects" and/or "events", so that a particular pattern, though part of one object (such as a wife), might trigger ideas of a completely different object (such as a remembered crisis). The only use we make of this distinction is to decide where to discuss each type of identification. The "identifications" gallery discusses high-level identification, while lower-level identification is left to the discussions of perception in general.
