Abnormal Psychology: the scientific study of mental
disorders and their treatment
What is Abnormal Psychology?
5. 5 of 53
Subjective Discomfort: Feelings of anxiety, depression,
or emotional distress. But people we would consider
definitely abnormal may not feel subjective discomfort.
Social Nonconformity: Disobeying societal standards for
normal conduct; usually leads to destructive or self-
destructive behavior. But it doesn’t always. Is being a
nonconformist always a disorder? 1984!
Statistical Abnormality: Having extreme scores on some
dimension, such as intelligence, anxiety, or depression.
But having a numerically rare characteristic isn’t always a
disorder (e.g., having an IQ of 180)
Ways of Defining “Abnormal”
7. 7 of 53
Situational Context: Social situation, behavioral setting, or
general circumstances in which an action takes place
Is it normal to walk around strangers naked? If you are in a
locker room and in the shower area, yes!
Cultural Relativity: Judgments are made relative to the
values of one’s culture
Two Considerations
8. 8 of 53
Maladaptive Behavior: Behavior that makes it difficult to

demands
Significant impairment in psychological functioning:
Those with mental illness lose the ability to control thoughts,
behaviors, or feelings adequately
Atypical behavior: behavior that is not typical of the
majority of the population

Pharmacotherapy
40. 40 of 53
Problems with Drug Therapy
• There can be serious side-effects (tranquilizers can cause
neurological disorders; Clozaril associated with a fatal blood
disorder)
• Drugs do not cure the disorder; they only ameliorate the
symptoms.
• Reliance on drugs increase belief in the “quick fix”; belief that
any disorder can be cured with a pill.
• Generally, psychotherapy is needed in addition to medication.
