Historical Perspectives on Abnormal behavior
The Ancient World China (200 BC) Chung Ching stated that
both organ pathologies & stressful psychological situations were causes of mental disorders.
GreeceHippocrates (377-460 BC) believed mental
illness was the result of natural, as opposed to supernatural, causes.
Galen (130-200 AD) divided the causes of mental disorders into physical and psychological explanations.
Middle Ages (500-1500 AD)
Islamic countries- a. mental hospitals were established (792 AD)b. Persian doctor Sina wrote the Canon of Medicine(medications).
Europe –abnormal behavior was most frequently viewed as demonic possession.
treatment entailed – prayer & exorcism.
The Renaissance AD
Spanish nun Teresa of Avila (1515-1582) established the conceptual framework that the mind can be sick.
Both Johann Weyer (1515-1588) of Germany and Scot (1538-1599) of England used scientific skepticism to refute the concept of demonic possession.
Humanitarian Reforms (18th-19th century)
In France, Philippe Pinel (1745-1826) pioneered a compassionate medical model for the treatment of the mentally ill & established a hospital in Paris.
In England, William Tuke (1732-1822) introduced trained nurses for the mentally ill & helped to change public attitudes regarding their treatment.
In US, Benjamin rush (1745-1813) founder of American Psychiatry, encouraged humane treatment of the mentally ill & hospitals.
Scientific Advances of the 20th Century
Development in technology such as MRI and PET scans have added to our knowledge of the biological bases of psychological disorder.
MRI PET Development in pscycho-pharmacology

BEHAVIOR DISORDERS PERSPECTIVES
Create Chart on back of time-line
Create Perspective Chart
PerspectiveExplanationTreatmentExampleIllustration
Medical PerspectiveExplanation:
Focus on biological and physiological factors as causes of abnormal behavior .
Treated as a disease, or mental illness, and is diagnosed through symptoms and cured
through treatment. Treatment: Hospitalization and drugs are
often preferred methods of treatment rather than psychological investigation.
Example: Schizophrenia needs medication to quiet voices, hallucinations and level dopamine.
Psychodynamic PerspectiveExplanation: Evolved from Freudian
psychoanalytic theory, which contends that psychological disorders are the consequence of anxiety produced by unresolved, unconscious conflicts(childhood).
Treatment: focuses on identification and resolution of the conflicts.
Example: Child neglected, no love will grow up to not love him/herself or others
Behavioral/Learning PerspectiveExplanation: Results from faulty or ineffective
learning and conditioning.
Treatments are designed to reshape disordered behavior and, using traditional learning procedures, to teach new, more appropriate, and more adaptive responses.
For example, a behavioral analysis of a case of child abuse might suggest that a father abuses his children because he learned the abusive behavior from his father and must now learn more appropriate parenting tactics
Cognitive PerspectiveExplanation: People engage in abnormal behavior
because of particular thoughts and behaviors that are often based upon their false assumptions. This is how the information is being decoded and retrieved (interpreted or memory issues).
Treatments are oriented toward helping the maladjusted individual develop new thought processes and new values.
Therapy is a process of unlearning maladaptive habits and replacing them with more useful ones.
Example: Anger issues from low road to high road
Social-Cultural Perspective
Explain: Abnormal behavior is learned within a social context ranging from the family, to the community, to the culture.
Treatment: Introducing and teaching the individual about in abnormal behavior within the culture by comparing and contrasting.
Example: Anorexia nervosa and bulimia are psychological disorders found mostly in Western cultures, which value the thin female body
Biological Perspective Views abnormal behavior as arising from a
physical cause, such as genetic inheritance, biochemical abnormalities or imbalances, structural abnormalities within
the brain, and/or infections Agrees that physical causes are of central
importance but also recognizes the influence of biological, psychological, and social factors in the study, identification,
and treatment of psychological disorders
Bio-Psych-Social Perspective
States Psychologists contend that ALL behavior, whether called normal or disordered arises from the interaction of nature and nurture. The bio-psycho-social perspective is a contemporary perspective which assumes that biological, sociocultural, and psychological factors combine and interact to produce psychological disorders.
