I hereby wish to present in a condensed form the ideas put forward in the three part Novelty Perception & the schizautistic spectrum essay, in particular those of its second part. The motivation of that essay was to postulate the ‘novelty perception threshold,’ a mechanism that solves the cognitive puzzle of having a functionally stable perception which is yet capable of adapting to new ideas, a puzzle that I suspect is not intuitively seen as a problem at all. A second motivation was to present this threshold as a personal variable which characterizes autism and schizophrenia as extreme ends of a single continuum that includes neurotypical individuals in the middle. This here text puts the ideas in a more concise form. For brevity I excluded the examples down to the footnotes.
