Document Summary
A linear model may hold that schizophrenia, for example, is caused by a chemical imbalance or by growing up surrounded by conflict: still encounter this, but most agree on multiple sources of behaviour. His behaviour may be an unconditional response to a movie with graphic, bloody scenes. Got so bad that saying cut it out left him queasy. Experienced a vasovagal syncope thus, causing his fainting. Increased hr and bp in film so, body compensated by lowering these, and amount of blood reaching his brain decreased significantly until he fainted: this seems to be inherited, which could be related to phobia in family history. Rapid increases in hr caused by emotions may have trigged a stronger, more intense, broreflex: this will increase or decrease bp in an effort to maintain homeostasis. Also made him avoid any situation related to blood and how he thought about certain situations. Principal rejected and dismissed his problem; may increase the effect.
