Models
of abnormal behavior
Ø Demonological Model—The view that abnormal behavior reflects invasion by
evil spirits or demons.

underlying illness.
§
Organic Version—Abnormal behavior patterns reflect
underlying biological or biochemical problems

·
Neurotic—Having a disorder theorized to stem
from unconscious conflict
·
Psychosis—Disorder in which a person lacks
insight and has difficulty meeting the demands of daily life and maintaining
contact with reality
Ø
Learning Model—abnormal behavior not a symptom of
underlying problem, rather it is the problem in itself (Learned through
interaction with environment and others)
Ø
Cognitive Model—focuses on cognitive events like
thought, expectations and attitudes that accompany or underlie psychological
disorders
Eclectic Psychologists—those that select from various systems or theories
v Classifying Abnormal

§
(Refer

Axes I and II—describe abnormal behavior
patterns
·
Axis III—describes physical illnesses and
conditions that may affect the understanding or treatment of abnormal behavior

v
Anxiety
Disorders
§
Anxiety—characterized by nervousness,
fears, feelings of dread and foreboding, and physical signs such as rapid
heartbeat and sweating

anxiety and helplessness that are caused by a traumatic experience (wars,
natural disasters), may include flash backs
Ø Theoretical Views
§
Social-Learning Views
·
Fears
may be acquired by observational learning
·
Obsessions
and compulsions divert attention from more important and threatening issues
(view shared by cognitive theorists)
§
Seligman and Rosenhan
(1984)—Prepared
Conditioning: The view that we are genetically predisposed to become
conditioned to certain stimuli
§
Benzodiaxepines—drugs that reduce anxiety
v Dissociative Disorders
§
Disorders
in which there are sudden, temporary changes in consciousness or self-identity

Ø Theoretical Views
§
Psychodynamic Theory—dissociative disorders use
repression or avert improper impulses
§
Learning Theory—dissociative disorders: people
learn not to think about disturbing acts in order to avoid guilt or shame
§
Social Learning Theory—role playing may be involved in
dissociative disorders like multiple personality
v Somatoform Disorders
§
people
complain of physical problems, though there is no evidence of physical
abnormality
Ø Conversion Disorder—anxiety or unconscious conflicts are converted into
physical symptoms that often have effect of helping the person with the
conflict

binge eating followed by purging as well as by persistent over-concern with

about 5% of population
Ø Theoretical Views
§
Psychoanalysts—anorexia
may be unconscious effort to remain prepubescent
§
Learning
Theorists—anorexia may come from a phobia concerning the possibility of gaining
weight
§
May
be connections to biology as well
