Supernatural view, where mysterious behavior
was attributed to supernatural powers, likely
dominated early societies
Naturalistic View, where abnormality is
attributed to medical problems.
Mental hospitals and asylums were used more
like prisons to keep the afflicted away from
society
Church dominance over culture in Middle
Ages and lack of scientific knowledge caused
the supernatural view to dominate through the
17th century.

One in four adults−approximately 61.5million
Americans−experiences mental illness in a given year. One in
17−about 13.6 million−live with a serious mental illness such as
schizophrenia, major depression or bipolar disorder.1
Approximately 20 percent of youth ages 13 to 18 experience
severe mental disorders in a given year. For ages 8 to 15, the
estimate is 13 percent.2
Approximately 1.1 percent of American
In 2005, 26.2 % of the U.S. population 18 and over had
experienced a mental disorder in the last year
› 6% suffered “serious” mental disorder
› According to 2004 census, that is over 50 million people

Most common disorders were anxiety, phobias, and mood
disorders
Anxiety Disorders
Defining Anxiety:
Anxiety is a general
feeling of fear and
apprehension that may be
related to an object or
event and is often
accompanied by increased
physiological arousal.

Conditioning
› For example, phobias can be learned through
classical conditioning
Feelings of not being in control can lead to
anxiety
 Predisposition to anxiety disorders may be
inherited (genetic)
 Displacement or repression of
unacceptable thoughts or impulses can
lead to anxiety

Prolonged vague but intense fears not
attached to any particular object or
circumstance
 Often results from Free-Floating Anxiety –
anxiety not attached to any particular
event or object
 Difficult to treat

Recurrent panic attacks in which the
person experiences intense terror without
cause
 Person is often left with fear of having
another panic attack
 Can lead to agoraphobia



Intense fear of specific
situations or objects
Agoraphobia
› Intense fear of crowds and public
places or other situations that
require separation from source of
security, such as the home

Social Anxiety Disorder
› Excessive fear of social situations
› Fear of scrutiny of others

Specific Phobia
› Common phobias include
animals, heights, closed places,
needles
Driven to disturbing
thoughts (obsessions)
and/or performing
senseless rituals
(compulsions)
 Individual recognizes
behavior is excessive but
cannot stop without
experiencing anxiety.
 “Washers” and “Checkers”
 Touching

Hoarding is now a
separate diagnosis
Psychologically distressing
experience (direct,
witnessed, indirect)
continues to plague
individual after the fact
and causes anxiety.
 Could result from either
personally experiencing or
witnessing a lifethreatening situation
 Often linked with combat
or rape


Somatoform Disorders
› Physical symptoms without any physical
cause
› Person experiences symptoms as real

Contrast with Psychosomatic Disorders…
› Real physical illness with psychological
causes such as stress or anxiety
› Tension headaches, for example
› Research indicates that most, if not all,
illnesses may have a psychosomatic
component

Freud
› Symptoms related to traumatic experience
in the past

Cognitive-behavioral
› Examines ways in which the behavior is
being rewarded, either tangibly or mentally

Biological perspective
› May be real physical illnesses that are
misdiagnosed or overlooked

Somatization Disorder– vague, recurrent physical
symptoms; plentiful and unrelated and
unresponsive to medical treatment (back pain, dizziness,
stomach pains, etc.)



Conversion Disorder – sudden but temporary loss of
physical functions triggered by psychological
factors.
› La belle indifference – apathy over loss of
functioning.
› Glove anesthesia – lack of feeling in hand only –
neurologically impossible.
› Hysterical blindness
Hypochondriasis – without physical evidence,
individual believes they have a serious illness
Body Dysmorphic Disorder – preoccupation with a
minor physical anomaly to the point of dysfunction.
Dissociative Disorders
Disorders in which conscious awareness
becomes separated from previous
memories, thoughts and feelings.
 Dissociative disorders are characterized
by a sudden but temporary alteration in
consciousness, identity, sensory/motor
behavior, or memory.
 These disorders are relatively rare, but
quite noticeable.

Seems to involve unconscious processes
 Memory impairments may also include
biological factors such as normal aging
and Alzheimer’s disease
 Dissociation is common with use of some
drugs such as LSD
 Trauma is often involved


Dissociative amnesia
› Loss of memory without a
physical cause (Freudian Rep?)

Dissociative fugue
› Flight from home and adoption
of a new identity and amnesia
for past events (Asnel Bourne)

Depersonalization disorder
› Person suddenly feels strangely
changed or different; “outside
self”

Dissociative identity disorder
› Person has several distinct
personalities that emerge at
different times
› Previously called multiple
personality disorder
Sexual Disorders

Include a range of sexual problems typically divided
into two categories
› sexual dysfunctions
› sexual desire disorders, known as paraphilias.

Difficult to diagnose!
› Sexuality is a private thing
› Difficult to label acts as “abnormal” or “normal”
› Kinsey’s research?
Additionally, must people be diagnosed for desire
or for acts or both? (Cannibal Case- Ex-NY Cop)
 Key factor in definition of sexual disorders: it causes
the individual stress and anxiety. This is a sign that
something is wrong, no matter how acceptable or
unacceptable the desire or behavior may be to the
rest of society.

Sexual dysfunctions involve an impairment
of “normal” sexual functioning.
 This can refer to an inability to perform or
reach an orgasm, painful sexual
intercourse, a strong repulsion of sexual
activity, or an exaggerated sexual response
cycle or sexual interest.
 A medical cause must be ruled out prior to
making any sexual dysfunction diagnosis
and the symptoms must be hindering the
person's everyday functioning.


Erectile disorder

› Inability of a man to
› Inability to reach
achieve or maintain an
erection

Female sexual
interest/arousal
disorder
orgasm in a person who
has sexual desire and
can maintain arousal


Sexual aversion
disorders
› Lack of sexual interest or
active distaste for sex
Premature ejaculation
› Male’s inability to inhibit
orgasm as long as
desired
› Inability of a woman to
become sexually
aroused or reach
orgasm
Orgasmic disorders

Vaginismus
› Involuntary muscle
spasms in the outer part
of the vagina making
intercourse impossible




Paraphilias all have in
common distressing and
repetitive sexual fantasies,
urges, or behaviors.
Must occur for a significant
period of time
Must interfere with either
satisfactory sexual relations or
everyday functioning if the
diagnosis of Paraphilic
Disorder to be made.
There is also a sense of
distress within these
individuals
› Typically recognize the
symptoms as negatively
impacting their life
› Feel as if they are unable to
control the symptoms

Pedophilic Disorder
› Preferred desire to have
sex with children
Involves a desire to become, or
insistence that one really is, a member of
the other sex
 Usually begins in childhood
 Most develop normal gender identity in
adulthood
 Gender correction surgery is an option
for adults who have this disorder
 Causes are not known

Mood Disorders
Mood disorders are characterized by
ongoing, dysfunctional emotional patterns
 Mood disorders are also referred to as
affective disorders
 An affect is another word for an emotion
 Mood disorders come in two general
categories, depressive disorders and
bipolar disorders


Biological factors
› Twin studies suggest genetic factors play a role
› Mood disorders may be linked to chemical imbalances in
the brain

Psychological factors
› Cognitive distortions: Maladaptive response to early
negative life events that leads to feelings of
incompetence and unworthiness
› These responses are reactivated whenever a new
situation arises that resembles the original events

Social factors
› Depression is linked to troubled close relationships
› May explain greater incidence of depression in women,
who tend to be more relationship-oriented
› Depressed people can evoke anxiety and hostility in
others, who then withdraw, which in turn can intensify
feelings of depression
In most cases, mood disorders are treated
with a combination of drug therapy and
talk therapy.
 In some extreme cases when these
methods do not work, ECT has been
effective.

› used rarely – if all other treatments fail
› Use if person is a serious harm to themselves or
others
› Not as heinous as depicted in films
Many more women are diagnosed with
mood disorders than men- Why?
 Psychologists have been researching both
biological and cultural causes for this.


General Symptoms:
› Overwhelming feelings of sadness
› Lack of interest in activities
› Excessive guilt or feelings of worthlessness

Types:
› Major depressive disorder
 Intense symptoms that may last for several months
› Dysthymic Disorder
 Less intense, but may last for periods of two years or
more
› Seasonal Affective Disorder (SAD)
 symptoms of depression triggered by weather patterns
(melatonin hypersensitivity)
› PPD (Postpartum depression)
 Depression with onset within 4 weeks of childbirth
Characterized by alternating between
depression and mania
 Manic-Depressive Disorder (Kelsey and
Chase)

› Periods of normal mood may come between
bouts of depression and mania
› Symptoms of Mania include




Feelings of euphoria
Extreme physical activity
Excessive talkativeness
Grandiosity
› Mania rarely occurs alone – it is typically part of
manic-depressive disorder
› Much less common than depression
› Stronger biological component than depression

Cyclothemia – less intense mood swings





Disorders in which maladaptive ways of
thinking and behaving learned early in life
cause distress in the person and/or conflicts
with others
Axis II in DSM
Rate among prisoners is close to 50%
They are often easy to identify in others, but
difficult to treat
Personality disorders are grouped by the
DSM into three groups or clusters
 Cluster
A: Odd or
Eccentric Behavior
› Paranoid
 Very suspicious of
others
› Schizoid
 Withdrawn and lacks
feelings for others
 Do not want or seek
social relationships

Cluster B: Dramatic or
Erratic Behavior
› Histrionic (Hysterical)
 Attention-hungry
 “drama-queen”
› Narcissistic
 exaggerated sense of
self-importance
› Antisocial - Ted Bundy
 Violates social norms
 Enjoys harming others
 Conduct Disorder
› Borderline
 Unpredictable, impulsive
and sometimes
destructive behavior
 Chaotic relationships

Cluster C: Anxious or Inhibited Behavior

 Wants relationships, but feels inferior
› Dependent
 Uncomfortable being alone
 Uncomfortable making decisions
› Obsessive-Compulsive
 Obsessed with order, lists, organizing
 Need for control over all aspects of life
Combination of biological
predisposition, adverse
psychological experiences,
and an unhealthy social
environment
 Also possible link to damaged
frontal lobe during infancy
 Emotional deprivation during
childhood may lead to
antisocial tendencies

I enjoy long walks on the
beach, soft music, oh,
and killing people.
Schizophrenia


Schizophrenia is the most debilitating and
complex of all the psychological disorders.
Diverse symptoms; one common denominator:
psychoticism
› Being psychotic means that the individual is suffering
from a break with reality that inhibits their ability to
function.


Additionally, there is ongoing evidence of
deteriorating social and intellectual
functioning.
The diagnosis must be made before age 45
and symptoms must persist for at least 6
months.
› One of: hallucination, delusion, disorganized speech
for classification

The Schizophrenic Experience

Most cases of schizophrenia are treated with
antipsychotic medication (dopamine ant.)
› Neuroleptics, Antipsychotics
› When these medications first were introduced,
they only treated some of the symptoms of the
disorder
› Tardive dyskinesia in long-term patients

Medications used now better treat both the
positive and negative symptoms of the
disease.
› Positive symptoms are symptoms people with
schizophrenia experience, but normal people do not
 Hallucinations, delusions, disorganized thought, movements
› Negative symptoms are behaviors that occur
normally, but do not in schizophrenics
 Flat affect, minimal speech


Symptoms have further been categorized by the effect they
have on functioning: disturbances of thought, perception,
and emotions
Thought Disturbances
Delusions - False beliefs about reality
› Language Disturbances (Word Salad- Unintelligible speech or language)
 Clang – rhyming speech pattern (The run sun done the gun; don't
drink drown down, brown gown." )
 Neologism – making up new words (Watch out for the flagoports)
 Loose Association – words don’t hold together; language does not
make sense ("I need to go to the store to buy some band-aids. I read
an article about how expensive AIDS drugs are. People take too many
street drugs. The streets should be clean from the rain today, etc" )
 Echolalia – repeating words over and over (also seen in autism)
›

Perceptual Disturbances
›

Hallucinations - Sensory experiences without external stimulation
Emotional Disturbances
Flat Affect – having no emotion
› Ambivalent Affect – having erratic emotional responses
›






Biological predisposition to schizophrenia may be
inherited
Twin studies show genetic link
Excessive levels of dopamine lead to psychotic
symptoms (hence, dopamine antagonists)
Abnormalities of brain structures (enlarged, fluidfilled ventricles)
Abnormal patterns of connections between
brain cells
May involve family relationships and social class
