Chapter 16 pt. 1: Perspectives on
Psychological Disorders and
Anxiety
Defining Psychological Disorder
A
Psychological Disorder is:
 a “harmful dysfunction” in which behavior
is judged to be:
1. atypical- not enough in itself
2. disturbing- varies with time &
culture
3. maladaptive- harmful; causes
suffering
4. unjustifiable- sometimes there’s a
good reason
History of Understanding
Psychological Disorders
 In
Ancient times, disorders were thought
to have been caused by movements of
the sun and moon (lunacy is full moon)
or by evil spirits.
 Treatments for people with mental illness
were very inhumane even up until the
mid 1900’s. Patients were often chained
like animals, beaten, burned, castrated,
etc.

have physical causes that can be diagnosed
based on their symptoms and be treated and in
most cases cured.

improves conditions in mental hospitals.

 Socio-Cultural?
Most Mental Health Professionals
Assume Disorders Have
Interlocking Causes

Bio-Psycho-Social
Perspective:
assume biological,
psychological,
and sociocultural factors
interact to produce
disorders.
Biological
(Evolution,
individual
genes, brain
structures
and chemistry)
Sociocultural
(Roles, expectations,
definition of normality
and disorder)
Psychological
(Stress, trauma,
learned helplessnes
mood-related perceptio
and memories)
Classifying Psychological
Disorders
 DSM-IV:

mental disorders up from 145
in the DSM-II (1968) and 60 in
DSM-I (1951).
17 categories
Does not explain
causes
Classifying Neurotic vs. Psychotic
Disorders
Neurotic disorder
 usually distressing but that allows one to
think rationally and function socially
 Freud saw the neurotic disorders as ways of
dealing with anxiety
 Psychotic disorder
 person loses contact with reality
 experiences irrational ideas and distorted
perceptions

Pros and Cons of the DSM-IV and
Labeling
 Pros?
Reliable
Need
a DSM diagnosis for insurance
 Cons?
Almost any behavior can be labeled
Distorts how we perceive others
Prejudice
Self fulfilling prophecy
Anxiety Disorders
Anxiety Disorders in general refer to
disorders that involve persistent and
distressing nervousness and apprehension
OR maladaptive behaviors which reduce
anxiety (defenses against anxiety).
 General Characteristics of Anxiety:
 Constant worrying, fear, or uncertainty
 Feels inadequate
 Oversensitive
 Difficulty concentrating
 May suffer insomnia

Anxiety Disorders
 Generalized
Anxiety Disorder:
person is tense, apprehensive, and in a
state of autonomic nervous system
arousal.
Anxiety Disorders
 Panic
Disorder:
disorder marked by
moments of intense
dread in which a person
experiences terror and
accompanying chest
pain or other
frightening sensations.
“Panic Attacks.”

Compulsive
Disorder (OCD):
disorder
characterized by
unwanted
repetitive
thoughts
(obsessions) and/or
actions
(compulsions).

Causes of Anxiety Disorders from
Learning Perspective (Behavioral)
 1.
Fear Conditioning : ex: rape victim may
develop fear of being alone in apartment.
 2. Stimulus Generalization: ex: fear of
heights leads to fear of flying even without
flying.
 3. Reinforcement (ENCOURAGES
behavior): avoiding places you have phobia
about rewards you by lessening your anxiety.
 4. Observational Learning/Modeling ex:
monkeys with snakes.
Causes of Anxiety Disorders from
Biological Perspective
1. Evolution: certain fears
help us survive.
 2. Genes: correlations with
identical twins and phobias.
 3. Physiology: brain
chemistry. Often see
increased brain activities in
brain areas involving impulse
control. Ex: picture
overactive frontal lobe
activity involved in directing
attention.
