Document Summary

Textbook: psychology tenth edition in modules authored by david g. myers. Nearly 1 in 100 people (about 60% of men) will develop schizophrenia, joining the estimated 24 million across the world. Schizophrenia means split mind not multiple-personality but rather split from reality that shows itself in disorganized thinking, disturbed perceptions, and inappropriate emotions and actions. It is the chief example of a psychosis, a disorder marked by irrationality and lost contact with reality. Disorganized thinking: delusions fragmented, bizarre, often distorted. Paranoid tendencies are prone to delusions of persecution. Disorganized thoughts may result from a breakdown in selective attention. Irrelevant, minute stimuli such as the grooves on a brick or the inflections of a oice may distract their attention from a bigger event or a speaker"s meaning. Disturbed perceptions: hallucinations (sensory experiences without sensory stimulation). May see, feel, taste, or smell things that are not there. Hallucinations are most often auditory frequently voices making insulting remarks or giving orders.
