Psychopathology
• In other words mental disorder or mental
illness
• According to the National Institutes of
Mental Health 15.4% of the population
suffers from a diagnosable mental health
problems
• Another study found that the behaviors of
over 56 million Americans meet the criteria
for a diagnosable psychological disorder
Changing Concepts of
Psychological Disorder
Different Perspectives:
Demonological
• The view that abnormal behavior reflect
invasion by evil spirits or demons.
• Stone Age humans developed trephiningthe practice of putting holes in the skull to
provide a passage for demons to get out of
the head
continued
• Trephining actually worked- today most
would agree b/c people were so afraid they
conformed to society.
• Ancient Greeks believed gods punished
people by causing confusion and madness
except Hippocrates (said Abnormal Behavior
caused by something in brain)
continued
• Massachusetts- Many believed ab. Behavior
was caused by possession of devil-called
these people witches( held responsible for
many things ranging from a neighbor’s
infertility to a poor yield of crops).
Cures
• An exorcist would pray for you and wave a
cross over you at night to send the devil
elsewhere…if that didn’t work you were
beaten, killed
• In Europe over 200,000 “witches” were
killed due to a publishing of manual of how
to recognize a witch.
• Salem witch trials
Witch testing
• Water-float test
• (pure metals sink to the bottom, impurities
float to surface) suspects who sank were
considered pure, those who kept their heads
above water were impure.
Historical Roots
• 400 B.C.- Hippocrates declared abnormal
behavior had physical causes.
• He taught symptoms of mental disorders
were a result of an imbalance among bodily
fluids (called humors)

Middle Ages
• Superstition eclipsed Hippocrates ideas
• Under the influence of the church,
physicians and clergy reverted back to
blaming abnormal behavior on demons,
witches, and the devil.
• The cure: torture, trephining, execution
The Medical Model
• Ab. Behavior is symptomatic of an
underlying illness.
• 2 version of model
*biological
*psychodynamic
The medical model
• Reemerged (from Hippocrates ideas) in the
late 18th century
• Diseases of the mind are like any other
disease
• Mental diseases have specific causes and
therefore must have specific treatments
How did this change view of
mental illnesses?
• Torture, executions, etc.. No longer made
sense
• Implemented asylums for the insaneinitially very therapeutic, later became
overcrowded and used as human
storehouses
Biological Version
• Ab. behavior reflects biological or
biochemical problems
• Term- mental illness
• Today- abnormalities in neurotransmitters,
the chemical that “conduct’ messages from
one cell in the nervous system to another.
continued
• Syndrome- a cluster or group of symptoms
suggestive of a particular order.
• Each mental illness presumably has specific
outcome and response to appropriate
therapy.
• DNA
continued
• Major advance over demonological
perspective—compassion over hatred
• Problem- mental hospital not always best
“cure”
• Today- receive treatment while staying in
society
Psychodynamic (Freud)Version
• Neuroses(neurotic behavior)- groups of
disorders theorized to stem from
unconscious conflict
• Abnormal behavior is a symptom of
unconscious childhood conflict
continued
• Psychosis- major disorder in which a
person lacks insight and has difficulty
meeting the demands of daily life and
maintaining contact with reality.
• Cure- resolve unconscious conflicts
Criticism of the medical
approach
• Too much reliance on doctor
• Patients became too passive/dependent on
doctor and/or drug treatments
• Little encouragement for the patient to take
part in ‘getting better”
Learning Perspectives
• Ab. Behavior may be caused by the fact that
one never got the chance to observe
“normal” behaviors and interactions.
• Inconsistent punishments
• Subculture reinforces behavior that is not
accepted by majority of population.
The Cognitive Perspective
• Ab. behavior caused by disturbances in how
one inputs, stores,manipulates, and retrieves
info.
• Disturbances caused by blocking input,
faulty storage, retrieval, or manipulation
Social-Cognitive-Behavioral
Perspective
• The alternative to the medical model that
view psychological disorders as a
combination of the social, cognitive, and
behavioral perspective.
