v     What is abnormal behavior?

Ø      Behavior is abnormal when...

§         It is unusual

§         It is socially unacceptable

§         One’s perception or interpretation of reality is faulty

·        Hallucination—A perception in the absence of sensory stimulation that is confused with reality

§         One is in severe personal distress

§        It is dangerous                

v    Models of abnormal behavior

Ø      Demonological Model—The view that abnormal behavior reflects invasion by evil spirits or demons.

Ø      The Medical Model—The view that abnormal behavior is symptomatic of an underlying illness.

§        Organic Version—Abnormal behavior patterns reflect underlying biological or biochemical problems

§        Psychodynamic Version—Abnormal behavior patterns reflect underlying psychological problems or conflicts

·       Neurotic—Having a disorder theorized to stem from unconscious conflict

·       Psychosis—Disorder in which a person lacks insight and has difficulty meeting the demands of daily life and maintaining contact with reality

Ø     Learning Model—abnormal behavior not a symptom of underlying problem, rather it is the problem in itself (Learned through interaction with environment and others)

Ø     Cognitive Model—focuses on cognitive events like thought, expectations and attitudes that accompany or underlie psychological disorders

Eclectic Psychologists—those that select from various systems or theories

v     Classifying Abnormal Behavior

Ø      Diagnostic and Statistical Manual of the American Psychiatric Association

§         Sorts abnormal behavior mainly on basis of observable similarities

§         (Refer to table 12.2 on page 482 of text)

·        Axes I and II—describe abnormal behavior patterns

·        Axis III—describes physical illnesses and conditions that may affect the understanding or treatment of abnormal behavior

·        Axes IV and V—further info that can affect prognosis and treatment (severity and functioning level)

v    Anxiety Disorders

§         Anxiety—characterized by nervousness, fears, feelings of dread and foreboding, and physical signs such as rapid heartbeat and sweating

Ø      Phobias—two types

§         Simple Phobias—persistent fears of specific objects or situations

§         Social Phobias—irrational excessive fears of public scrutiny

Ø      Post-Traumatic Stress Disorder-intense and persistent feelings of anxiety and helplessness that are caused by a traumatic experience (wars, natural disasters), may include flash backs

Ø      Theoretical Views

§         Social-Learning Views

·        Fears may be acquired by observational learning

·        Obsessions and compulsions divert attention from more important and threatening issues (view shared by cognitive theorists)

§         Seligman and Rosenhan (1984)—Prepared Conditioning: The view that we are genetically predisposed to become conditioned to certain stimuli

§         Benzodiaxepines—drugs that reduce anxiety

v     Dissociative Disorders

§         Disorders in which there are sudden, temporary changes in consciousness or self-identity

§         Psychodynamic Theory—dissociative disorders use repression or avert improper impulses

§         Learning Theory—dissociative disorders: people learn not to think about disturbing acts in order to avoid guilt or shame

§         Social Learning Theory—role playing may be involved in dissociative disorders like multiple personality

v     Somatoform Disorders

§         people complain of physical problems, though there is no evidence of physical abnormality

Ø      Conversion Disorder—anxiety or unconscious conflicts are converted into physical symptoms that often have effect of helping the person with the conflict

Ø      Hypochondriasis—persistent belief that one has a medical disorder despite lack of medical findings

Ø      Theoretical Views

§         Psychodynamic Theory—conversion disorders are used for reduction of guilt or shame, and possibly even to serve a purpose

v     Eating Disorders

Ø      Anorexia Nervosa—eating disorder characterized by maintenance of an abnormally low body weight, intense fear of weight gain, a distorted body image, and amenorrhea in females

§         Amenorrhea—absence of menstruation

§         1 in 200 school-aged girls has trouble gaining or maintaining weight

§         Usually begins in adolescence (between 12 and 18)

Ø      Bulimia Nervosa—eating disorder characterized by recurrent episodes of binge eating followed by purging as well as by persistent over-concern with body shape and weight

§         Ratio women:men is about 10:1

§         Affects about 5% of population

Ø      Theoretical Views

§         Psychoanalysts—anorexia may be unconscious effort to remain prepubescent

§         Learning Theorists—anorexia may come from a phobia concerning the possibility of gaining weight

§         May be connections to biology as well

v    Mood Disorders

¨      Depressed people tend to interoperate failures through internal, stable, and global perspectives.  They feel helpless.

·        Organic Factors

¨      Mood swings tend to run in families

¨      Norepinephrine a neurotransmitter could have a role in depression is there is a minimal amount of it.

¨      Depression could be reduced by enhancing sensitivity of norepinephrine receptors.
