CHAPTER 14 • Psychoses – a class of psychological disorders in which reality contact-the capacity to perceive, process, and respond to environmental stimuli in an adaptive manner-is radically impaired, with the result that the person sometimes cannot meet even the most ordinary demands of life. 3 main groups:  Mood Disorders – disturbances in mood.  Schizophrenia – disturbance of thought.  Delusional Disorder – limited system of delusions. • Schizophrenia – the label given to a group of psychoses in which deterioration of functioning is marked by sever distortion of thought, perception, and mood, by bizarre behavior, and by social withdrawal. Men are more likely to develop. Symptoms of Schiz: 1) Delusions 4) Disorganized or Catatonic Behavior. 2) Hallucinations 5) Negative Symptoms - reduction of normal 3) Disorganized speech functions such as language or goal- directed behavior. Must show 2 of these for at least 6 months in order to be diagnosed as schizophrenia. Delusions – firmly held beliefs that have no basis in reality. Categories of Delusions: 1) Delusions of Persecution – one is being plotted against, spied upon, threatened, interfered with, etc. 2) *Delusions of Control (aka Influence) – other people, forces, or perhaps extraterrestrial beings are controlling one’s thoughts, feelings, and actions, often by means of electronic devices. 3) Delusions of Reference – one is being referred to by events or stimuli that in fact have nothing to do with one. 4) Delusions of Sin and Guilt – one has committed ‘the unpardonable sin’ 5) Hypochondriacal Delusions – one is suffering from a hideous physical disease. 6) Nihilistic Delusions – one or others or the whole world has ceased to exist. 7) Delusions of Grandeur – one is an extremely famous and powerful person.
