"the experience of anomalous perceptions, beliefs and behaviors"
"this is simply a term pointing to the experience of anomalous perceptions, beliefs and behaviors ..."
The only thing that I have found that most people can really agree on with regard to what gets called "psychosis" is that this is simply a term pointing to the experience of anomalous perceptions, beliefs and behaviors (i.e., perceptions, beliefs and behaviors that are not in line with those that are generally experienced, believed or condoned/understood within the individual's broader culture). These kinds of experiences can vary radically between individuals, suggesting that what we call "psychosis" is highly heterogeneous in its manifestation, ... I personally believe that certain core existential dilemmas or themes (or "problems in living," as some like to call them) very often come to the fore when people are having such experiences, but that the manifestation is highly individualized depending upon the person's particular history, past traumas, current situation/culture, etc. I discuss this extensively in my book, "Rethinking Madness," and my other articles here: http://www.rethinkingmadness.com
