David Rosenhan suspected that terms such as sanity, insanity, schizophrenia, mental illness, and abnormal might
have fuzzier boundaries than the psychiatric community thought.
He also suspected that some strange behaviors seen in mental patients might originate in the abnormal
atmosphere of the mental hospital, rather than the patients themselves.

Dangers of LabelingDavid RosenhanBeing Sane in Insane Places
In 1973 sociologist David Rosenhan
designed a clever study to examine the difficulty that people have shedding the
"mentally ill" label. He was particularly
interested in how staffs in mental
institutions process information about
patients.
Rosenhan & seven associates had themselves committed to different mental hospitals complaining of hearing voices. All but one were diagnosed as schizophrenic.
•Once admitted, they acted totally normal.
•Remained hospitalized for average 19 days (9 to 52)
•Only the patients detected their sanity
•When discharged their chart read, “schizophrenia in remission”
No professional staff member at any of the hospitals ever realized
that any of Rosenhan’s pseudopatients was a fraud.
According to a study conducted by the National Institute of mental health:
*15.4% of the population suffers from diagnosible mental health problems
*56 million Americans meet the criteria for a diagnosible psychological disorder (Carson 1996, Regier 1993)
*Over the lifespan, +/- 32% of Americans will suffer from some psychological disorder. (Regier1988)
Normal or Abnormal?Normal or Abnormal?
Not easy task:
*Is Robin Williams normal? Anna Nicole Smith? Marilyn
Manson? Karl Rove?
*Is a soldier who risks his life or her life in combat normal?
*Is a grief-stricken woman unable to return to her
routine three months after her husband died normal?
Is a man who climbs mountains as a hobby
normal?
Some abnormalities are easy:
Hallucinations (false sensory experiences)
Delusions (extreme disorders of thinking)
Affective problems (emotion: depressed, anxious, or lack of emotion)
CORE CONCEPT:
Medical model: takes a “disease” view
Psychology model: interaction of biological, mental, social, and behavioral factors
SHOW:
Psych in Film, Ver.2, #33, Patch Adams
Psychological Disorder– a “harmful dysfunction” in which
behavior is judged to be:• atypical- (not enough in itself)• disturbing- (varies with time & culture)• maladaptive- (harmful)• unjustifiable- (sometimes there’s a good
reason)

THE WORLD OF AbNORMAL BEHAVIOR:
#1 Looking at Abnormal Behavior
#2 The Nature of Stress
Carol D. Ryff argues that we must define mental illness in terms of the positive. She names 6 core dimensions:
1)1) Self-acceptanceSelf-acceptance:
positive attitude towards self
multiple aspects of self
positive about past life
2)2) Positive self relations with other peoplePositive self relations with other people:
warm, trusting, satisfying interpersonal relationships
capable of empathy, affection, intimacy
3) Autonomy3) Autonomy
independent, self-determined
able to resist social pressures
4) Environmental mastery4) Environmental mastery:
sense of mastery and competence
makes good use of opportunities
creates contexts that support their personal needs
5) Purpose of Life5) Purpose of Life:
has goals and directedness
feels there is meaning to past and present life
6) Personal Growth6) Personal Growth:
see oneself as growing and expanding
open to new experiences
change in ways that reflect self-knowledge and effectiveness

Psychological Disorders
Medical Model*concept that diseases have physical causes*can be diagnosed, treated, and in most
cases, cured*assumes that these “mental” illnesses can
be diagnosed on the basis of their symptoms and cured through therapy, which may include treatment in a psychiatric hospital
Psychological DisordersBio-psycho-social
Perspective*assumes that biological,
sociocultural, and psychological factors combine and interact to produce psychological disorders
Biological(Evolution, individual
genes, brain structures
and chemistry)
Psychological(Stress, trauma,
learned helplessness, mood-related perceptions
and memories)
Sociocultural(Roles, expectations, definition of normality
and disorder)
Psychological Disorders- Etiology
DSM-IV-TR*American Psychiatric Association’s
Diagnostic and Statistical Manual of Mental Disorders (Fourth Edition)
*a widely used system for classifying psychological disorders
*presently distributed as DSM-IV-TR (text revision)
*today used as “convenient shorthand”“convenient shorthand” to avoid labeling.
DSM-IV-TR organizes each psychiatric diagnosis into five levels (axes) relating to different aspects of the disorder or disability:
1)1) Axis 1Axis 1 -- Clinical disorders including major mental disorders, as well as developmental or learning problems. Common disorders in this category include depression, bipolar, anxiety, ADHD, and schizophrenia.
2)2) Axis 2Axis 2 -- Pervasive or personality disorders, including mental retardation. Common disorders in this category include borderline PD, schizotypal PD, narcissistic PD, antisocial PD, paranoid PD.
DSM-IV-TR continued:
3) Axis 33) Axis 3 -- Acute medical conditions and physical disorders. Common disorders in this category include brain trauma, brain injury, brain disease..
4) Axis 44) Axis 4 -- Psychosocial and environmental factors contributing to the disorder. Common factors in this category include a man suffering from depression after losing his job, or his wife dying, et. al.
5) Axis 55) Axis 5 -- Global Assessment of Functioning or Children’s Global Assessment Scale (under 18)
Psychological Disorders- Etiology
Neurotic disorder (term seldom used now)*usually distressing but that allows one to think
rationally and function socially
*Freud saw the neurotic disorders as ways of dealing with anxiety
Psychotic disorder*person loses contact with reality
*experiences irrational ideas and distorted perceptions
PREPAREDNESS HYPOTHESIS:
Suggests that we have an innate biological tendency, acquired through natural selection, to respond quickly and automatically to stimulti that posed a survival threat to our ancestors. (Ohman & Mineka, 2001)
This explains why we develop phobias for snakes and lightening more easily than others.

1) Depressive Disorders 1) Depressive Disorders *most common disorders”*most common disorders” a mood disorder in which a person, for no apparent reason, experiences
two or more weeks of depressed moods, feelings of worthlessness, and diminished interest or pleasure in most activities

appetite changes, insomnia, inability to concentrate, worthlessness, hallucinations
b) Dysthymia Unhappy for over 2 years
He believed that:
•depressed people draw illogical conclusions about themselves.
•Created the BECK SCALES for labeling clinical depression.
Aaron Beck is called the
FATHER OF COGNITIVE THERAPY
Aaron Temkin Beck (1921-?)
Professor, Univ Pennsylvania
PhD: Brown, Yale
Beck believed that depressed people blame themselves for normal problems and consider every minor failure a
catastrophe.
DRUG TREATMENTS for depression:
*tricyclic antidepressants:
*first to be used--not used as much today.
*affect 2 neurotransmitters: norepinephrine & serotonin
*side affects: drowsiness & weight gain, increased heart rate, decrease in blood pressure, blurred vision, dry mouth, confusion
*SSRI (Selective Serotonin Reuptake Inhibitor)
*side effects: nausea, diarrhea, tremors, weight loss, headache
*less likely to affect the heart
*some people feel more agitated and anxious on SSRIs, and can become increasingly suicidal if not detected and treated.
Mood Disorders2) Bipolar Disorder2) Bipolar Disorder
*a mood disorder in which the person alternates between the hopelessness and lethargy of depression and the overexcited state
of mania*formerly called manic-depressive disorder
a) Manic Episode a mood disorder marked by a hyperactive, wildly optimistic state, excessive excitement, silliness, poor judgment, abrasive, rapid flight
of ideas
b) Major depression Lethargic, sleepy, social withdrawal, irritability
Symptoms of Mania
1)1) Mood or emotional symptomsMood or emotional symptoms: euphoric, expansive, and elevated. In some cases, dominant mood is irritability. Even when euphoric, manic people are close to tears and if frustrated, will burst out crying.
2)2) Grandiose cognitionGrandiose cognition: manics believe no limits to their abilities and do not recognize the painful consequences of trying to carry out their
plans. May be delusional about themselves.
3)3) Motivational symptomsMotivational symptoms: hyperactivity has intrusive, dominating, domineering quality. Some engage in compulsive gambling, reckless driving, or poor financial investment.
4)4) Physical symptomsPhysical symptoms: lessened need for sleep. After a few days, exhaustion settles in.
•Between .6 and 1.1 percent of
U.S. population will have bipolar disorder in their
lifetime.
•It affects both sexes equally.
•Onset is sudden.
•First episode occurs between ages 20 and 30.

Aaron Beck’s work with depressed patients convinced him that depression is primarily a disorder of thinking rather than of mood. He argued that depression can best be described as a cognitive triadcognitive triad or negative thoughts about oneself, the situation or the future.
Cognitive errors included the following:
1) overgeneralizing: drawing global conclusions about worth, ability, or performance on basis of single fact
2) Selective abstraction: focusing on one insignificant detail and ignoring others
3) Personalization: incorrectly taking responsibility for events in the world
4) Magnification & minimization: bad events magnified and good events minimized.
5) Arbitrary inference: drawing conclusions without sufficient evidence
6) Dichotomous thinking: seeing everything in one extreme or its opposite.

DISSOCIATIVE DISSOCIATIVE DISORDERSDISORDERS
Dissociative Disorders
Dissociative Disorders– conscious awareness becomes separated
(dissociated) from previous memories, thoughts, and feelings
Dissociative Disorders
1) Psychogenic Amnesia– Sudden inability to recall important
information--NOT as a result of physical “blow” or drug-related.
2) Psychogenic Fugue– Loss of memory--flees to a new location and
establishes new lifestyle– After recovery, events during fugue are not
remembered
DUE TO EXTREMESTRESS!!
Dissociative Disorders3) Dissociative Identity Disorder
– rare dissociative disorder in which a person exhibits two or more distinct and alternating personalities
– formerly called multiple personality disorder*often history of child or sex abuse
In 2008, Herschal Walker, the 1982 Heisman Trophy winner from the University of Georgia, released his book “Breaking Free” which related his experiences with DID. He reported not being able to remember winning the Heisman in 1982 or darker events, such as threatening his then-wife.
4) Depersonalization Disorder– Persistent, recurring feelings that one is not
real or is detached from one’s own experience or body.
depression,
mood swings,
suicidal tendencies,
sleep disorders (insomnia, night terrors, and sleep walking),
panic attacks and phobias (flashbacks, reactions to stimuli or "triggers"),
alcohol and drug abuse,
compulsions and rituals,
psychotic-like symptoms (including auditory and visual hallucinations),
eating disorders
headaches,
amnesias,
time loss,
trances, and "out of body experiences."
self-persecution,
self-sabotage
violence (both self-inflicted and outwardly directed).
People with Dissociative Disorders may experience any of the following:
Dissociative Disorders are now understood to be fairly common effects of severe trauma in early severe trauma in early childhoodchildhood, most typically extreme, repeated physical, sexual, and/or emotional abuse.
Posttraumatic Stress Disorder (PTSD), widely
accepted as a major mental illness affecting
8% of the general population in the United States, is closely related to Dissociative Disorders.
In fact, 80-100% of people diagnosed with a
Dissociative Disorder also have a secondary
diagnosis of PTSD
Recent research
suggests the risk of suicide
attempts among
people with trauma
disorders may be even higher than
among people who have major depression.
There is evidence that people with
trauma disorders have higher rates of
alcoholism, chronic medical
illnesses, and abusiveness in
succeeding generations.
TREATMENTS:TREATMENTS:
*Medical model:*Medical model: therapy to recall the memories, hypnosis or a medication called Pentothal (thiopental) can sometimes help to restore the memories
*Psychoanalysis: *Psychoanalysis: help an individual deal with the trauma associated with the recalled memories. Fugue--Hypnosis. Dissociative identity disorder-- long-term psychotherapy that helps the person merge his/her multiple personalities into one.
*Learning Theories:*Learning Theories:
*Behaviorists:*Behaviorists:
*Cognitive Therapies:*Cognitive Therapies: irrational interpretations
*Humanistic:*Humanistic: client-centered therapies, responsibility, active-listening.
SCHIZOPHRENIC SCHIZOPHRENIC DISORDERSDISORDERS
(also called Psychotic Disorders)(also called Psychotic Disorders)
Schizophrenia literally means “split mind,” meaning a split from reality that shows itself in disorganized thinking, disturbed
perceptions and inappropriate emotions and actions.
PSYCHOTIC: split from reality
The term coined by Emil KraepelinEmil Kraepelin, who
established the diagnostic category
“dementia praecox” and Eugen BleulerEugen Bleuler, who introduced the term
“schizophrenia.”1874, Medicene, Leipzig & Wurtzburg,
Germany
(1857-1939) Medicene, University
of Bern
Possible symptoms of psychotic illnesses include:
*Disorganized or incoherent speech
*Confused thinking
*Strange, possibly dangerous behavior
*Slowed or unusual movements
*Loss of interest in personal hygiene
*Loss of interest in activities
*Problems at school or work and with relationships
*Cold, detached manner with the inability to express emotion
*Mood swings or other mood symptoms, such as depression or mania
CAUSES:
•chemical imbalances (“mad as a hatter”)
•excess D4 dopamine receptors (in autopsies) (drugs that block dopamine receptors lessen the symptoms)
•now researching neurotransmitter glutamate (direct neurons to pass along an impulse)
•abnormal brain activity: low in frontal lobes
•research shows (during hallucinations) increased activity in thalamus, amygdala, and cortex
•greater than normal cerebral cortex tissue loss between ages 13 and 18.
•genetics: enlarged, fluid-filled cranial cavities
Identical Twin studies show:
*48% probability of having schizophrenia if your twin does.
*single placenta: 6 in 10 chance
*separate placentas: 1 in 10 chance
*one study showed the older the father, the greater risk of schizophrenia in offspring
The GENAIN QUADRUPLETS (b.1930) were monozygous woman all suffered from schizophrenia, demonstrating a large genetic component to the disease. The girls (Nora,
Iris, Myra, Hester) were fictitiously named for NIMH (National Institute of Mental Health). Both parents had
mental disorders during their lifetime.
A common finding in the brains of
people with schizophrenia is
larger than normal lateral
ventricles.
DIATHESIS-STRESS HYPOTHESIS:
The idea that biological factors may place the individual at risk for schizophrenia (or
others), but environmental stressors transform this potential into an actual
disorder.
1) DISORGANIZED
2) CATATONIC
3) PARANOID
4) UNDIFFERENTIATED
5) RESIDUAL
*6) PARANOID DELUSIONAL DISORDER
1) DISORGANIZED SCHIZOPHRENIC
• confused and incoherent,
• jumbled speech
• emotionless or flat or inappropriate, even silly or childlike. (flat affect or lack of affect)
• disorganized behavior that may disrupt their ability to perform normal daily activities (showering or preparing meals)
• hallucinations and delusions
Disorganized speech is of two types:
NEOLOGISMS: “new words”
WORD SALAD: “disorganization”
“I had belly bad luck and brutal and outrageous.” (I have
stomach problems and don’t feel good) “I gave all the work money. (I paid tokens for my meal) I was raised in packs (with
other people) and since I was in littlehood (little girl) she blamed a few people with minor words (she scolded people).
The lion will have to change from dogs into cats until I can meet my father and mother and we depart some rats. I live on the front part of Whitton’s head. You have to work hard if you don’t get into bed. She did. She said, “Hallelujah, happy landings.” It’s all over for a squab true tray and there ain’t not squabs, there ain’t no men, there ain’t no music, there ain’t no nothing besides my mother and my father who stand alone upon the Island of Capri where there is no ice, there ain’t no nothing but changers, changers, changers…….
2) CATATONIC SCHIZOPHRENIC
•Physical symptoms
• immobile and unresponsive to the world around them
• very rigid and stiff, unwilling to move
• waxy flexibility
• occasional grimacing or bizarre postures.
• might repeat a word or phrase just spoken by another person.
• increased risk of malnutrition, exhaustion, or self-inflicted injury.
Catatonic excitement: patients become agitated and hyperactive.
3) PARANOID SCHIZOPHRENIC
• preoccupied with false beliefs (delusions) about being persecuted or being punished by someone
• thinking, speech and emotions, however, remain fairly normal.
•the paranoid delusions of persecution or grandiosity (highly-exaggerated self-importance) are less well organized--more illogical--than those of the patient with purely delusional disorder.
•delusions are usually auditory
4) UNDIFFERENTIATED SCHIZOPHRENIC
* diagnosed when the person's symptoms do not clearly represent one of the other three subtypes.
5) RESIDUAL SCHIZOPHRENIC
* suffered from schizophrenia in the past but no hallucinations or delusions
• mildly disturbed thinking
• emotionally impoverished
**6) PARANOID DELUSIONAL DISORDER
• characterized by non-bizarre delusions in the absence of other mood or psychotic symptoms
•delusions involving real-life situations that could be true, such as being followed, being conspired against or having a disease
• delusions persist for at least one month.
• non-bizarre refers to situations such as: being followed, being loved, having an infection, or being deceived by one’s spouse
• needs to be evaluated with respect to religious and cultural differences.

Personality DisordersPersonality Disorders
*disorders characterized by inflexible and enduring behavior patterns that impair social functioning
*usually without anxiety, depression, or delusions
**In contrast to other psychological problems, PDs do NOT want to change. They believe the problem lies with the
“other” person.15% of the American population are affected with personality disorders (Mayo
Clinic)….46.5 million people
About one in seven U.S. adults has at least one personality disorder, and many have more than one.

Personality Disorder Types
1) Paranoid Personality Disorder * Belief that others are lying, cheating, exploiting or trying to
harm you
* Perception of hidden, malicious meaning in benign comments
* Inability to work collaboratively with others
* Emotional detachment
* Hostility toward others
CAUSES:*Might be learned…. might be traced back to childhood experiences. *Studies of identical and fraternal twins suggest that genetic factors may also play an important role in causing the disorder. Twin studies indicate that genes contribute to the development of childhood personality disorders.
