Early Theories of Psychological Disorders
• Afflicted people were possessed by evil spirits.
• Movements of sun or moon*lunacy = full moon
Early Theories
• Music or singing was often used to chase away spirits.
•In some cases trephening was used:
Cutting a hole in the head of the afflicted to let out the evil spirit
Ancient Treatments• Another theory was to make the body extremely
uncomfortable• Ancient treatments included: exorcism, caged like
animals, beaten, burned, castrated, mutilated, blood replaced with animal’s blood
History of Mental Disorders
• In the 1800’s, disturbed people were no longer thought of as madmen, but as mentally ill.
Did this mean better treatment?
They were first put in hospitals.
Early Mental Hospitals• They were nothing more than barbaric
prisons.
•The patients were chained and locked away.
•Some hospitals even charged admission for the public to see the “crazies”, just like a zoo.
Philippe Pinel
• French doctor who was the first to take the chains off and declare that these people are sick and “a cure must be found!!!”

***Most psychologists do not pick just one perspective for their practice but pick a combination of them; this is called being eclectic.
Current Perspectives
• Medical Perspective: psychological disorders are sicknesses and can be diagnosed, treated and cured. concept that diseases have physical causes 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
Current Perspectives
• Bio-Psycho-Social Perspective: assumes biological, psychological and sociocultural factors combine and interact causing psychological disorders
Used to be called Diathesis-Stress Model: diathesis meaning predisposition; stress meaning environment
Bio-Psycho-Social Perspective:
Sane or Insane?
• Insane is a legal term to benchmark whether or not a person is capable of committing a crime. Psychologists almost never use that term (unless they are getting paid a lot of money to testify in court).
DSM IV• Diagnostic
Statistical Manual of Mental Disorders: the big book of disorders.
• DSM will classify disorders and describe the symptoms.
• DSM will NOT explain the causes or possible cures.
Two Major Classifications in the DSM

Dissociative Amnesia• Localized amnesia is present in an individual who has no
memory of specific events that took place, usually traumatic. The loss of memory is localized with a specific window of time. For example, a survivor of a car wreck who has no memory of the experience until two days later is experiencing localized amnesia.
