  1. Abnormal Psychology Chapter 10 The scientific study of mental disorders and their treatment Prepared byJ. W. Taylor V

  2. Abnormal Psychology • College reading: • 363 – 365 general info about disorders and DSM 5 – • 375 – 380 schizophrenia • READING QUIZ SOON….

  3. This unit is about… • The Diagnosis and Classification of Mental Disorders • Three Major Categories of Mental Disorders • The Treatment of Mental Disorders

  4. What is abnormal behavior? • Write 3 characteristics

  5. Criteria for a Behavior/Thought Process to be a “Disorder” 1. Is the behavior/thought process atypical? 2. Is the behavior/thought process maladaptive? 3. Is the behavior/thought process personally distressing? 4. Is the behavior/though process irrational?

  6. Perceptual Bias of Labeling Problem: when we classify mental disorders we label people, and this biases our perception of these people in terms of the labels • Ex: the word “crazy” has strong connotations

  7. Mental disorders fall into 4 major categories • Anxiety disorders:highly anxious or fearful behaviorEx: • Mood disorders:emotional extremes Ex: • Schizophrenic disorders:disorganized thinking, disturbed perceptions, inappropriate actions/emotionsEx: • personality disorders: inflexible, long-standing personality traits, impaired social functioning, deviate from cultural norms • Ex:

  8. Diagnostic and Statistical Manual: Official book of mental disorders • The DSM-IV, published in 1994 by the American Psychiatric Association, is the most widely used diagnostic system for disorders • First appeared in 1952. At that time, 60 disorders. • Now contains more than 300 disorders • DSM-IV classification required by health insurance companiesbefore they will pay for therapy

  9. Three Major Categories of Clinical Disorders

  10. By the way… • Be wary of the medical school syndrome: the tendency to think that you have a disorder when you read about its symptoms • It’s normal to feel depressed, spazz out, have occasional OCD etc… • Remember, to be abnormal your behavior must be: • Atypical • Maladaptive • Personally distressing • Irrational

  11. Schizophrenic disorder • http://www.youtube.com/watch?v=2QJMWk4bnMo • What are 3 of Jani’s symptoms/behaviors? • Describe how her behavior fits the definition of “abnormal”. • Do you feel her parents are responding appropriately? Why/not? • http://www.youtube.com/watch?v=VuBps0Fnawg

  12. Schizophrenic disorder • Is NOT multiple personality disorder • Schizophrenics have one personality, but it is disorganized and irrational • They typically • Have hallucinations (hear voices) • Are delusional (irrational beliefs, ex: “I am a messenger of God”) • Are paranoid (“the government is spying on me”) • Have erratic emotional responses/violent outbursts

  13. Many homeless people are schizophrenic

  14. How does the prevalence of schizophrenia compare to other disorders?

  15. Create a profile • http://www.schizophrenia.com/szfacts.htm

  16. Pair assignment – profile of a schizophrenic • Make a detailed profile of a person who is schizophrenic • Include their name, age, living conditions, personality and other personal identifying information • Describe their schizophrenic symptoms. Be descriptive, and realistic (base on research) • Describe any treatment, relapses, family response etc

  17. Grading criteria • BEST poster: all members get 11 points! • Second best: all members get 10 • Third: 9 • And so on • It’s a competition!!

  18. Schizophrenic Disorders • More people are institutionalized with schizophrenia than any other disorder • About 1% of the population suffers from schizophrenia • The onset tends to be in late adolescence or early adulthood • Tends to strike men earlier and more severely, though both sexes are equally vulnerable • Higher incidence in lower socioeconomic groups and for people who are single, separated or divorced rather than married

  19. What does this graph tell us about schizophrenia?

  20. Schizophrenia • Is a psychotic disorder because it is characterized by a loss of contact with reality • Schizophrenia means “split mind,” as mental functions do indeed become split from each other and detached from reality

  21. Symptoms of Schizophrenia • Positive symptoms are abnormal behaviors that exist, but should not. Added symptoms. • Hallucinations(false sensory perceptions) • Hallucinations tend to be auditory, such as hearing voices that are not real • Delusions (false beliefs) • Delusions of persecutions involve thoughts of conspiracy against you • Delusions of grandeur involve believing that you are a person of great importance, such as Jesus Christ

  22. Symptoms of Schizophrenia • Negative symptoms refer to things that have been removed • Loss of emotion, energy, social activity, even drives like hunger • Disorganized symptoms include disorganized speech, disorganized behavior, and inappropriate emotion • When the person’s speech is disorganized, it might be like a “word salad,” with unconnected words incoherently spoken together

  23. Technical Definition • According to the DSM-IV, schizophrenia is defined as the presence, most of the time during a one-month period, of at least two of the following symptoms • Hallucinations • Delusions • Disorganized speech • Disorganized or catatonic behavior • Any negative symptoms (such as loss of emotion)

  24. Catatonic schizophrenia • This person might sit frozen in this position for hours • Is this a positive, negative or disorganized symptom?

  25. Five Subtypes of Schizophrenic Disorder

  26. Schizophrenics • What type of schizophrenic are these people? What are their symptoms? https://www.youtube.com/watch?v=bWaFqw8XnpA

  27. Type I and Type II • Another distinction is between Type I and Type II schizophrenia • Type I schizophrenia is characterized by positive symptoms • Type II schizophrenia is characterized by negative symptoms • Type I is more acute, as the person functioned normally before the disorder strikes and has a better chance of recovery because Type I can usually be alleviated with drugs, whereas Type II tends to stem from more permanent brain abnormalities

  28. Causes of Schizophrenia • Concordance rate is about 50%, although no particular genes have been identified, and it is possible different genes might be involved in the different types of schizophrenia • One hypothesis involves prenatal viral infections • People are at increased risk if there was a flu epidemic during the middle of their fetal development • In the northern hemisphere, people born in the winter/spring months, January through April, following the fall/winter flu season, are more at risk than people born other months of the year

  29. Causes of Schizophrenia • A second hypothesis involves neurotransmitters • Schizophrenics have elevated levels of dopamine activities in certain areas of their brains • A third hypothesis involves various brain abnormalities, especially among those with Type II schizophrenia • Shrunken cerebral tissue and enlarged fluid filled areas • The thalamus seems to be smaller and the frontal lobes less active in many schizophrenic brains

  30. Causes of Schizophrenia • A popular bio-psycho-social explanation is the vulnerability-stress-modelthat contends that genetic, prenatal, and postnatal biological factors render a person vulnerable to schizophrenia, but environmental stress determines whether it develops • A person’s level of vulnerability interacts with the stressful social-cognitive events in their live to determine the likelihood of schizophrenia • The disorder does tend to strike in late adolescence and early adulthood, periods of unusually high stress levels

  31. Perspectives • The causes of abnormal behavior and thinking can be found in the four major research perspectives • Biological • Behavioral • Cognitive • Sociocultural • However, no one perspective adequately explains even one disorder • The biopsychosocial approachto explaining abnormality examines the interaction between biological, behavioral, cognitive, and social/cultural factors

  32. Treatment • Fortunately, schizophrenia can be successfully treated with antipsychotic medications • If the patient continues to take them, the disorders stays away • If they stop, the symptoms return • Problem: many schizophrenics don’t identify as such, or are too paranoid to swallow pills

  37. Anxiety Disorders Disorders in which excessive anxiety leads to personal distress and atypical, maladaptive and irrational behavior Specific Phobia Social Phobia & Agoraphobia Panic Disorder Generalized Anxiety Disorder Obsessive-Compulsive Disorder

  38. Phobia: irrational fear • A strong and persistent fear of specific objects/situations that is excessive or unreasonable (irrational)

  39. Specific Phobia • For example, there was woman with a specific phobia of birds. • She became housebound because of her fear of encountering a bird. Any noises she heard within the house she thought were birds that had broken in to get her. • When she did leave the house, she was careful not drive near any birds, because if she hit a bird, they would take revenge on her. • She knew her fears were irrational, but she could not control their effects on her behavior and thinking.

  40. Causes of Specific Phobias • Classical conditioning • In Little Albert study, the infant was conditioned to fear white rats by pairing together a loud startling noise (an unconditioned stimulus) with a white rat (a conditioned stimulus) • CREATE ANOTHER EXAMPLE:Biological predispositions • Some people are naturally more nervous and scared • Certain associations (such as taste and sickness) are easy to learn, while others (such as taste and electric shock) are much more difficult to learn

  41. Phobia treatment • Systematic desensitization • Slow, progressive exposure to the stimulus that causes fear • Gradual exposure leads to lessening of fear • Start with “safe” stimulus and build up

  42. Social Anxiety/Phobia • Fear or anxiety of social interaction • Hard time making eye contact • Nervous at parties, social events • Feels extremely self conscious, awkward • AVOIDS social interaction because too difficult to deal with • Much stronger than introverted personality

  43. http://www.youtube.com/watch?v=gmEJEfy5f50 Start at 5.55

  44. Agoraphobia • A fear of being in places or situations from which escape might be difficult or embarrassing • Includes crowds, standing in line, traveling in a crowded bus, stuck in heavy traffic • People avoid such situations, won’t leave home

  45. Panic Disorder • A condition in which a person experiences recurrent panic attacks • Sudden onsets of intense fear • Can be triggered by stressful event (giving a speech) or NO apparent reason • Symptoms: • Difficulty breathing • Chest pain • Feel like going to faint • FEAR!! And PANIC!

  46. Generalized Anxiety Disorder • Excessive, global anxiety and worry • General sense of dread, fear, anxiety • Cannot control • Period of at least 6 months • Anxiety not tied to any specific object or situation (not a phobic disorder) • May be related to low GABA, a calming neurotransmitter • People with generalized anxiety disorder may have problems with activation of GABA, allowing more and more neurons to get excited

  47. Obsessive-Compulsive Disorder • recurrent obsessions (thoughts) and/or compulsions (behaviors) • cause significant distress and disruption in the person’s daily life • An obsession is a persistent intrusive thought, idea, impulse, or image that causes anxiety • A compulsion is a repetitive and rigid behavior that a person feels compelled to perform to reduce anxiety
