Amnestic Occlusion is an effect that may lock a set of information behind a meme (perhaps a word, a phrase or image) which has an amnestic property to it, preventing the associated information from being recorded in a viewers mind. These "amnestic locks" may only be circumvented by a viewer inoculated to that specific meme- that is, typically, possessing meta-knowledge of the meme such that its effects are less pronounced. This could, for instance, take the form of a word with inherent amnestic properties, a word that could go overlooked by a viewer despite its presence in apparently plain sight. It is difficult to provide a tangible example.
Consider perhaps how the mind processes an article like "the" constantly in everyday speech, without ever taking much time to consider the word's meaning or properties. It is a similar concept to this. Once attention has been drawn to the word, the brain may process it differently for a time, rendering the apparent innocuousness negated.
