Final exam (Chapters 13, 14, 15 and some review) Flashcards
Psychopathology:
The study of abnormal thoughts, feelings, and behaviors
biological model
Disordered behavior and thinking are caused by biological changes
in the chemical, structural, or genetic
systems of the body.
Cognitive perspective
Maladaptive functioning comes from irrational beliefs and illogical patterns of thought.
Biopsychosocial model
Disordered thinking or behavior is the result of the combined and interacting forces of biological, psychological, social, and cultural influences.
Psychodynamic model
Abnormal thinking and behavior stem from repressed conflicts and urges that are fighting to become conscious.
Behaviorism
Abnormal behavior is learned.
Cultural relativity:
Need to consider norms and customs of another culture when diagnosing person from that culture with a disorder
- Cultural syndromes
Sociocultural perspective:
Abnormal/normal thinking or behavior is product of behavioral shaping within context of:
- Family influences
- Social group to which one belongs
- Culture within which family and social group exist
Diagnostic and Statistical Manual of Mental Disorders (DSM)
- First published in 1952
- Revised multiple times as knowledge and ways of thinking about psychological disorders has changed.
- Most recent edition published in 2013, the DSM-5
Phobia:
Irrational, persistent fear of an object, situation, or social activity
Social anxiety disorder (social phobia):
Fear of negative evaluation in social situations
Specific phobias:
Fear of particular objects, situations, or events
Agoraphobia:
Fear of place/situation from which escape is difficult or impossible
Panic disorder:
Frequent, disruptive panic attacks
Panic attack:
Sudden, intense panic; multiple physical and emotional symptoms
Generalized Anxiety Disorder
- Feelings of dread/doom and physical stress lasting at least six months
- Source of anxiety often cannot be pinpointed
- Worry about things most people would not worry about
Obsessive-Compulsive Disorder
- With DSM-5, this disorder is no longer classified as an anxiety disorder.
- Now falls in the category of “Obsessive-Compulsive and Related Disorders.”
- Obsessive, recurring thoughts create anxiety.
- Compulsive, ritualistic, repetitive behavior or mental acts reduce that anxiety.
Acute stress disorder (ASD)
Occur immediately after a traumic event
Posttraumatic stress disorder:
Symptoms include persistent ASD lasting longer than a month or can emerge as late as six months after trauma
Acute stress disorder (ASD)
and
Posttraumatic stress disorder
Both disorders are no longer classified as anxiety disorders in the DSM-5
Causes of Anxiety Disorders
- Psychodynamic:
Repressed urges and desires trying to come into consciousness, create anxiety that is controlled by the abnormal behavior or thinking
Causes of Anxiety Disorders
- Behavioral
Disordered behavior learned through operant and classical conditioning techniques
Causes of Anxiety Disorders
- Cognitive
Excessive anxiety comes from illogical, irrational thought processes
Causes of Anxiety Disorders
- Biological
Nervous system dysfunction, genetic transmission
Bipolar and Related Disorders and Depressive Disorders
Affect: An emotional reaction
Disorders of mood: Disturbances in emotion ranging from mild to moderate, or can be extreme
Major Depressive Disorder:
Severe depression, sudden, no apparent external cause
Most common of the diagnosed disorders of mood
1.5 to 3 times more likely in women as it is in men
Bipolar I Disorder:
Mood spans from normal to manic, with or without episodes of depression
Bipolar II Disorder:
Normal mood with episodes of major depression and episodes of hypomania
Bipolar Disorder and ADHD
Possible connection between ADHD and adolescent onset of bipolar disorder.
Significantly higher rates of ADHD among relatives of individuals with bipolar disorder.
Irrational thinking and mania are common in bipolar not present in ADHD.
Hyperactivity can be present in both disorders.
Causes of Disordered Mood
- Behavioral
Link depression to learned helplessness
Causes of Disordered Mood
- Cognitive
See depression as the result of distorted, illogical thinking
Causes of Disordered Mood
- Biological
Variation in neurotransmitter levels or specific brain activity; genes and heritability play a part
Anorexia Nervosa
BMI less than 18.5 in adults
Vomiting, laxative abuse, food restriction, and excessive exercise used to control food intake
Bulimia Nervosa
Binging large quantities of food with attempts to rid self of food through inappropriate means
Binge Eating Disorder
Uncontrolled binge eating, but no attempts to purge or use inappropriate methods to avoid weight gain
Causes of Eating Disorders
- Adolescents and young adults are most at risk.
- Eating disorders have been observed in non-Western cultures that are not focused on thinness.
- Genetic components for eating disorders account for 40 to 60 percent of the risk for anorexia, bulimia, and binge-eating disorder.
Dissociative disorders:
Break in conscious awareness, memory, and/or sense of identity
Dissociative amnesia:
Memory loss for personal information, either partial or complete
- Can occur with or without dissociative fugue, sudden travel away from home with amnesia for trip and possibly personal identity
Dissociative identity disorder:
Person seems to have two or more distinct personalities
Causes of Dissociative Disorders
- PSYCHODYNAMIC:
Point to repression of memories, seeing dissociation as a defense mechanism against anxiety
Causes of Dissociative Disorders
- COGNITIVE AND BEHAVIORAL
Trauma-related thought avoidance is negatively reinforced by reduction in anxiety and emotional pain
Causes of Dissociative Disorders
- BIOLOGICAL:
Lower than normal activity levels in areas responsible for body awareness; depersonalization disorder
Schizophrenia:
Severely disordered thinking, bizarre behavior, inability to separate fantasy from reality
Symptoms of Schizophrenia
- POSITIVE
Excesses of, or additions to, normal behavior
Delusions: Unshakeable, false beliefs
Hallucinations: Seeing or hearing things that don’t exist
Symptoms of Schizophrenia
- NEGATIVE
Less than, or an absence of, normal behavior
Poor attention
Flat affect: A lack of emotional responsiveness
Poor speech production
Causes of Schizophrenia
- Positive symptoms appear to be associated with overactivity of dopamine areas of the brain; negative with lower dopamine activity
- Stress-vulnerability model: Suggests people with genetic markers for schizophrenia will not develop the disorder unless they are exposed to environmental or emotional stress at critical times in development
Causes of Schizophrenia
- Genetics, brain structural defects have been implicated
- Genetics supported by twin and adoption studies
Causes of Schizophrenia
- Biological roots supported by universal lifetime prevalence across cultures of approximately 7–8 people out of 1,000
Causes of Schizophrenia
Stress-vulnerability model: Suggests people with genetic markers for schizophrenia will not develop the disorder unless they are exposed to environmental or emotional stress at critical times in development
Personality disorders:
Persistent, rigid, maladaptive behavior interfering with normal social interaction
Borderline personality disorder:
- Moody
- Unstable sense of identity
- Clings to others
- More common in women
Antisocial personality disorder:
- Disorder is more common in men.
- Symptoms:
- May habitually break the law, disobey rules, or tell lies with no regard for others’ feelings.
- Indifferent, or able to rationalize taking advantage of or hurting others.
- Disorder is more common in men.
Causes of Personality Disorders
- COGNITIVE-BEHAVIORAL:
Specific behaviors learned over time, associated with maladaptive belief systems
Causes of Personality Disorders
- GENETIC FACTORS:
Biological relatives of people with personality disorders more likely to develop similar disorders
Causes of Personality Disorders
- STRESS TOLERANCE:
Individuals with antisocial personality disorder are emotionally unreactive to stress or threat, and have lower than normal levels of stress hormones
Causes of Personality Disorders
- FAMILY RELATIONSHIPS:
Linked to disturbances in family communications and relationships
Therapy

- Action
- Goals
