2 Defining Abnormality To study the abnormal is the best way of understanding the normal. William James (1842-1910)
4 Defining Psychological Disorders Is being abnormal enough to call something a disorder?
7 Medical Model physicians discovered that syphilis led to mental disorders 1.Etiology 2.Diagnosis 3.Treatment 4.Prognosis
8 The Biopsychosocial Approach
9 Classifying Psychological Disorders
10 Multiaxial Classification Note 16 syndromes in Axis I
11 Goals of DSM 1.Describe (400) disorders. 2.Determine how prevalent the disorder is. Disorders outlined by DSM-IV are reliable.
12 Labeling Psychological Disorders 1.Critics of the DSM-IV argue that labels may stigmatize individuals. Asylum baseball team (labeling) Elizabeth Eckert, Middletown, NY. From L. Gamwell and N. Tomes, Madness in America, 1995. Cornell University Press.
13 Labeling Psychological Disorders 2.Labels may be helpful for healthcare professionals when communicating with one another and establishing therapy.
14 Labeling Psychological Disorders 3.How should the label affect responsibility? http://www.radiolab.or g/2010/jun/28/ Theodore Kaczynski (Unabomber) Elaine Thompson/ AP Photo
15 Anxiety Disorders Feelings of excessive apprehension and anxiety. Often includes the symptom of panic attacks. 1.Generalized anxiety disorder 2.Panic disorder 3.Phobias 4.Obsessive-compulsive disorder 5.Post-traumatic stress disorder
16 Generalized Anxiety Disorder Symptoms
17 Panic Disorder Symptoms
19 Obsessive-Compulsive Disorder
20 A PET scan of the brain of a person with Obsessive-Compulsive Disorder (OCD). High metabolic activity (red) in the frontal lobe areas are involved with directing attention. Brain Imaging Brain image of an OCD
21 Post-Traumatic Stress Disorder Four or more weeks of the following symptoms 1.Haunting memories 2.Nightmares 3.Social withdrawal 4.Jumpy anxiety 5.Sleep problems Bettmann/ Corbis
22 Resilience to PTSD Only about 10% of women and 20% of men react to traumatic situations and develop PTSD.
23 Explaining Anxiety Disorders Freud suggested that we repress our painful and intolerable ideas, feelings, and thoughts, resulting in anxiety.
24 The Learning Perspective fear conditioning observational learning John Coletti/ Stock, Boston
25 The Biological Perspective Natural Selection Genetic inheritance
26 The Biological Perspective Generalized anxiety, panic attacks, and even OCD are linked with brain circuits like the anterior cingulate cortex.
27 Dissociative Disorders Conscious awareness becomes separated (dissociated) from previous memories, thoughts, and feelings. Symptoms 1.Having a sense of being unreal. 2.Being separated from the body. 3.Watching yourself as if in a movie.
32 Bipolar Disorder Multiple ideas Hyperactive Desire for action Euphoria Elation Manic Symptoms Slowness of thought Tired Inability to make decisions Withdrawn Gloomy Depressive Symptoms

34 Explaining Mood Disorders Lewinsohn et al., (1985, 1998) note that a theory of depression should explain the following: 1.Behavioral and cognitive changes 2.Common causes of depression
35 Theory of Depression 3.Gender differences
36 Theory of Depression 4.Depressive episodes self-terminate. 5.Stressful events often precede depression. 6.Depression is increasing, especially in the teens. Post-partum depression Desiree Navarro/ Getty Images
38 Biological Perspective Genetic Influences: Mood disorders run in families. The rate of depression is higher in identical (50%) than fraternal twins (20%).

43 Schizophrenia 1.Disorganized and delusional thinking. 2.Disturbed perceptions. 3.Inappropriate emotions and actions.
Types of Schizophrenia
45 Symptoms of Schizophrenia Positive symptoms versus Negative symptoms
46 Disorganized & Delusional Thinking Does selective attention failure play a part?

48 Inappropriate Emotions & Actions
49 Onset and Development of Schizophrenia Nearly 1 in a 100 suffer from schizophrenia (WHO, 2002). Usually diagnosed between age 18-24
50 Chronic and Acute Schizophrenia When schizophrenia is slow to develop (chronic/process) recovery is doubtful. Such schizophrenics usually display negative symptoms. When schizophrenia rapidly develops (acute/reactive) recovery is better. Such schizophrenics usually show positive symptoms.
51 Understanding Schizophrenia Schizophrenia is a disease of the brain exhibited by the symptoms of the mind. Dopamine Overactivity Brain Abnormalities
52 Abnormal Brain Activity Brain scans show abnormal activity in the frontal cortex, thalamus, and amygdala of schizophrenic patients. Paul Thompson and Arthur W. Toga, UCLA Laboratory of Neuro Imaging and Judith L. Rapport, National Institute of Mental Health

57 Personality Disorders inflexible and enduring behavior patterns that impair social functioning. Antisocial Personality Disorder Borderline Personality Disorder Narcissistic Personality Disorder
Symptoms – Trouble regulating emotions – Quick to anger – Fear of abandonment – Impulsiveness – Rocky relationships – Suicidal thoughts and attempts Understanding Borderline Personality Disorder

61 Understanding Antisocial Personality Disorder PET scans of 41 murderers revealed reduced activity in the frontal lobes. In a follow-up study, repeat offenders had 11% less frontal lobe activity (Raine et al., 1999; 2000). Normal Murderer Courtesy of Adrian Raine, University of Southern California
